The Romanian Orthodox Church

At first glance, the nationalist ideology of the French Revolution seems to have had little impact on the Orthodox Church in Romanian-speaking territories. Romanians were the predominant inhabitants of the principalities of Wallachia and Moldavia and the neighboring territories of Transylvania (including Crişana, Maramureş and Banat), Bukovina, Bessarabia, and Dobrudja. The majority of ethnic Romanians belonged to the Orthodox faith while their communities were at the intersection of geopo liti cal interests of the Rus sian, Ottoman, and Habsburg empires. In 1859 the Principalities of Wallachia and Moldavia (known as the Old Kingdom between 1866 and 1918) united into a single state under the rule of a local prince. The term "Romania" began to be used by the new state in its of cial documents in 1862. Two years later, the state supported the declaration of a Romanian autocephalous (in de pen dent) church that was recognized by the Ecumenical Patriarchate in 1885. As an integrative part of the Orthodox commonwealth, the church was situated between the competing jurisdictions of the Ecumenical Patriarchate and the Rus sian Orthodox Church, while its declaration of autocephaly followed a pattern in the spread of national churches in Southeastern Europe. From the Treaty of Kuchuk Kainardji of 1774 to the beginning of the Greek War for In de pen dence in 1821, the Romanian principalities were under the suzerainty of the Ottoman Empire, which had full control of their po liti cal and economic affairs. The sultan appointed princes, and the Porte determined their po liti cal and judicial status. The princes were drawn from the "Phanariots," and were directly appointed by the Porte from preponderantly Greek elite rather than the Romanian local elite, the boyars (boieri).1 In each principality, the church was headed by a metropolitan who was under the direct jurisdiction of the Ecumenical Patriarchate. That religion mattered to local population as a means of social cohesion was suggestively depicted by Anatole de Demidoff, an En glish traveler in the region in 1837. Arriving in Bucharest, the capital of Wallachia, he claimed that: I know of no city in Europe in which it is possible to find more agreeable society, or in which there is a better tone, united with the most charming gaiety⋯. Religion, which is here of the schismatic Greek creed, does not, properly speaking, hold any great empire over the minds of the Wallachian people, but they observe its outward forms, and particularly the austerities of fasting, with scrupulous exactitude. The people are seen to attend divine ser vice with every sign of respect, and the great number of churches existing in Wallachia, bear witness to the ardent zeal with which outward worship is honored.2 The Romanian Orthodox Church was a national institution, closely linked to social, economic, and po liti cal structures. In most cases, Orthodox hierarchs were appointed from the families of boyars, thus ensuring a close relationship with the state authorities and its policies. As one of the largest landowners in the principalities, the church had a prime role in administrating healthcare and education. Although the majority of the clergy was uneducated, it dispensed both ecclesiastical and civil justice and in many cases worked closely with boyars in local administration.3 The lower clergy not only contributed directly to the economy but also benefited from tax privileges. Some small villages had an unusually high proportion of clergy in comparison to the overall population. For example, in 1810, Stənisləveşti, a village in the south of Wallachia, was composed of eleven houses and had two priests, five deacons, and three cantors; similarly, the Frəsinet village of nineteen houses had two priests and five deacons.4 Although these cases were exceptional, they indicate both the economic value of being a member of the clergy and the wider canonical dimension of church jurisdiction. The special status of the clergy was reflected not only at lower but also at higher levels. Bishops and metropolitans engaged with state policy and in many cases opposition to the authorities led to the loss of a spiritual seat. The metropolitan of each principality worked with the prince and was president of the divan, the gathering of all boyars. He held the right to be the first person to comment on state policy and to make recommendations when the prince was absent. The metropolitan replaced the prince when the principality had no political ruler, such as in the cases of Metropolitan Veniamin Costachi of Moldavia in 1806 and Metropolitan Dositei Filitti of Wallachia, while the bishops of Buzəu and Argeş were members of the provisional government during the Rus sian occupation of the principalities in 1808. The higher clergy had both religious and political prerogatives in relation to foreign powers as evident in their heading of the boyars' delegation to peace negotiation between the Rus sian and Ottoman empires at Focşani in 1772 and addressing memoranda to the Austrian and Rus sian governments in 1802.5 The primary role of the church in the principalities of Moldavia and Wallachia was paralleled by the national mobilization of Orthodox communities in the neighboring territories that had Romanian inhabitants. Although throughout the region Orthodox communities were incorporated into church structures as part of the Habsburg, Austrian or Rus sian empires, the nineteenth century was characterized by the leadership's search for political autonomy and the building of a Romanian national identity. The Orthodox communities outside the Old Kingdom maintained relations with the faithful in principalities across the Carpathian Mountains and the Dniester River and sought support in their struggle for political and religious rights.

Orthodox Christianity and Nationalism:an introduction

On the morning of January 5, 1859, at the end of the liturgy in the Orthodox cathedral in Iaşi, the capital of the principality of Moldavia, Father Neofit Scriban addressed the congregation. He had given many sermons in the cathedral; however, on this par tic u lar date Father Neofit faced an unusual audience. Among the faithful who regularly worshipped at the relics of Saint Parascheva, the protector of Moldavia, were the members of the assembly who would decide the future of the principality. They had a specific mission: to elect a new prince, a key figure in their plan to unite Moldavia with the neighboring principality of Wallachia. Father Neofit, a supporter of the unionist cause and fully aware of the significance of the moment, stated: Brethren, Jesus Christ has said that "For where two or three have gathered together in My name, I am there in their midst." You, Brethren, are not two, or three, but a real gathering in the name of God. God is in your midst. You are here in the name of the Romanian nation [and] the Romanian nation is in your midst. On the flag under which you have assembled, the flag of the Romanian nation, great events, the Romanian faith, unity, are written in large letters. The church, which is founded on faith, blesses the flag of this faith⋯. You, Brethren, through the faith of the Romanian nation, by remaining faithful to this flag, will find the same strength as the church [finds] in its own saints. The faith of the Romanian nation was not, is not, and will not be anything else, but the unity of all Romanians in a single state, the only anchor of salvation, the only port in which the national boat could be saved from surrounding waves. You, Brethren, have gathered here in the church of Stephen the Great; looking at the altar that he raised to the God of your parents, I think that, through this [altar], you will be able to enter into the wishes of this hero of our nation. You, [remember that] by leaving this place, you are leaving [in order to fulfill] a great gesture that for many centuries has been lost for us; you are about to elect a successor to this great hero; therefore, as his true sons, you could not be anything other than the true expression of his wishes. Myself, [as] last year, from this altar, I said and I will continue to say that this great hero has told us that "the God of our parents will send us a Redeemer who will heal our wounds and accomplish our wishes." May your chosen leader today be the redeemer expected by the Romanian nation. May he heal its wounds and achieve its wishes. Therefore, Brethren, may your election today be that of a real Messiah of Romania. God and the world are looking at you, the church is blessing you and the whole Romanian nation is waiting for you!1 A few hours after Father Neofit's sermon, the assembly elected Alexandru Ioan Cuza to be the prince of the principality of Moldavia; a few days later, on January 24, 1859, the assembly of the neighboring principality of Wallachia decided that Cuza should also be their prince, thus confirming the unification of the two states. A new country was inscribed on the map of Southeastern Europe, titled "The United Principalities of Wallachia and Moldavia," also known as "The United Romanian Principalities".

Base-free, one-pot chemocatalytic conversion of glycerol to methyl lactate using supported gold catalysts

We report an efficient one-pot conversion of glycerol (GLY) to methyl lactate (MLACT) in methanol in good yields (73 % at 95 % GLY conversion) by using Au nanoparticles on commercially available ultra-stable zeolite-Y (USY) as the catalyst (160 °C, air, 47 bar pressure, 0.25 M GLY, GLY-to-Au mol ratio of 1407, 10 h). The best results were obtained with zeolite USY-600, a catalyst that has both Lewis and Brønsted sites. This methodology provides a direct chemo-catalytic route for the synthesis of MLACT from GLY. MLACT is stable under the reaction conditions, and the Au/USY catalyst was recycled without a decrease in the activity and selectivity. From glycerol to green building blocks and solvents! An efficient, base-free conversion of glycerol to methyl lactate in methanol is reported, achieving good yields (73 % at 95 % glycerol conversion) using Au/ultra-stable zeolite-Y (USY) as the catalyst and environmentally benign oxygen as the oxidant by combining two separate reaction steps efficiently in a one pot procedure. The Au/USY catalyst can be recycled without a decrease in the activity and selectivity. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Hot-spots during the calcination of MCM-41:a SAXS comparative analysis of a soft mesophase

The phenomenon of microscopic hot-spots, during the calcination of MCM-41, was investigated by quantifying the magnitude of the temperature increase during the calcination of a soft MCM-41 mesophase using a SAXS comparative study. This was performed by thermally treating a soft material that was detemplated via Fenton chemistry followed by equilibrating and drying in a low-surface-tension solvent (n-butanol or N,N-dimethylformamide); these samples have limited structural shrinkage. The resulting samples were thermally treated at increasing temperatures, and the structural shrinkage was compared with that of the directly calcined material. By comparing the structural shrinkage, it was found that the microscopic temperature increase would fall between 190 and 250 C, as deduced from N,N-dimethyl-formamide and n-butanol. The order of magnitude of the temperature increase appears to be consistent with the well-known glow effect. It is, however, substantially higher than the experimentally determined macroscopic temperature increase. Several aspects are discussed to interpret this difference. © 2013 Elsevier B.V.

Detemplation of soft mesoporous silica nanoparticles with structural preservation

A mild protocol that allows the template removal of soft un-aged silica nanoparticles was investigated. After oxidizing the organic template by Fenton chemistry, a good structural preservation is only achieved when the material is equilibrated and dried in a low-surface tension solvent. This avoids excessive capillary stress induced by the high surface tension of water, a major component in the Fenton reaction medium. The Fenton reaction should be carried out under mild conditions as well; otherwise the sample deteriorates by extensive hydrolysis, and capillary stress, and the structural ordering diminishes severely. We propose employing 10 ppm Fe concentration at 70 °C for 24 h for the cetyltrimethylammonium bromide template. The proposed protocol involves 2 steps resulting in an overall significantly higher pore volume attributed to the wider pores and limited particle agglomeration, while the calcined counterpart evidences aggregation and loss of the hexagonal ordering. n-BuOH exchange is unnecessary when the mesophase is stabilized by ageing, as the structure resists the water capillary stress. © The Royal Society of Chemistry 2013.

Direct activation of microcrystalline zeolites

In this work a direct activation route of zeolites is assessed. It consists of NH4-exchanging the as-synthesized solids before removing the organic template. Calcination afterwards serves to combust the organic template and creates the Brønsted sites directly; thus applying merely a single thermal step. This method simplifies their activation and the material suffers less thermal stress. The approach was particularly effective for microcrystalline beta and ferrierite zeolites. Thorough investigation of the template content and materials' texture points out to three relevant effects that can explain the effective exchange process: partial removal of the template during exchange creates substantial microporosity (ferrierite), the remaining template is reorganized within the pores (ferrierite) and finally, void space can exist due to the non-perfect matching between the network and template (beta). This shorter method appears suited for microcrystalline zeolites; it was ineffective for crystalline MFI types. © 2013 Elsevier B.V. All rights reserved.

Condensation-enhanced self-assembly as a route to high surface area α-aluminas

High surface area nanosized α-alumina has been obtained by thermally treating a sol-gel-derived mesophase at 1200 C; the mesophase was synthesized by a sol-gel route involving evaporation induced self-assembly (EISA) of a hydrolyzed gel from Al-tri-sec-butoxide in s-BuOH in the presence of a nonionic surfactant (EO20PO70EO20), HCl as catalyst, and water (H2O/Al = 6). The activated material renders moderate surface areas of about 8.4-10 m2 g-1, associated with significant crystallite coarsening. The key aspect to produce smaller crystallites is making the mesophase more resistant to coarsening. This was achieved by enhancing the condensation step by treating the hydrolyzed gel with tetrabutyl ammonium hydroxide (TBAOH) before evaporation. The characteristics of the mesophase indicate condensation of the primary particles with less AlO5 unsaturated sites, at the expense of a lower solid yield due to small crystallites dissolution. The activated TBAOH condensed EISA material is composed of α-alumina aggregated crystallites of about 60-100 nm, and the material possesses surface areas ranging from 16 to 24 m2 g -1 due to the improved resistance to coarsening. At least two aspects are suggested to play a role in this. The worm-hole morphology of the mesophase aggregates yields high particle coordination, which favors densification rather than coarsening. Furthermore, the decrease of the AlO5 defect sites by the TBAOH condensation makes the mesophase less reactive and consequently more resistant to coarsening. © 2013 American Chemical Society.

Thermal detemplation of SBA-15 mesophases. Effect of the activation protocol on the framework contraction

The potential use of the solvothermal extraction (SE) as a preliminary step to calcination for detemplating SBA-15 mesophases is investigated; aiming to reduce the amount of organics to be burnt and thereby the corresponding structural shrinkage. A systematic study was carried out by soxhlet extraction on mesophases hydrothermally aged between 90 and 130 C. The mesophases containing variable amounts of template were then treated by calcination or pyrolysis/calcination. TGA was applied to quantify the template amount after the various treatments. The as obtained materials were characterized by SAXS and Ar ad/desorption for structural and textural information while 1H NMR gave information about the integrity of the as-recycled template. The study shows that solvothermal conditions remove considerably the template, typically from 50 to 10-20 wt.%, mainly extracted from the primary mesopores. Possible reuse of the extracted template is questionable as it is poor in polyethyleneoxide compared to the synthesis block-copolymer, Pluronic P123. For all thermal protocols applied (direct calcination, calcination after solvent-extraction or pyrolysis/calcination after solvent extraction), the thermal shrinkage decreases with the aging temperature; that is consistent with the condensation degree of the silica. For each mesophase, it was found that the thermal shrinkage becomes less pronounced when the material is fully templated; thus the template can serve as structural support or can control the mass transfer of O2 and thereby the oxidation rate of the template burning. © 2013 Elsevier Inc.

Oxidative dehydrogenation of ethylbenzene to styrene over alumina:effect of calcination

Commercially available γ-Al2O3 was calcined at temperatures between 500 and 1200 °C and tested for its performance in the oxidative ethylbenzene dehydrogenation (ODH) over a wide range of industrially-relevant conditions. The original γ-Al2O 3, as well as η- and α-Al2O3, were tested. A calcination temperature around 1000/1050 °C turned out to be optimal for the ODH performance. Upon calcination the number of acid sites (from 637 to 436 μmol g-1) and surface area (from 272 to 119 m 2 g-1) decrease, whereas the acid site density increases (from 1.4 to 2.4 sites per nm2). Less coke, being the active catalyst, is formed during ODH on the Al-1000 sample compared to γ-Al 2O3 (30.8 wt% vs. 21.6 wt%), but the coke surface coverage increases. Compared with γ-Al2O3, the EB conversion increased from 36% to 42% and the ST selectivity increased from 83% to 87%. For an optimal ST selectivity the catalyst should contain enough coke to attain full conversion of the limiting reactant oxygen. The reactivity of the coke is changed due to the higher density and strength of the Lewis acid sites that are formed by the high temperature calcination. The Al-1000 sample and all other investigated catalysts lost ODH activity with time on stream. The loss of selectivity towards more COX formation is directly correlated with the amount of coke. © The Royal Society of Chemistry 2013.

Catalyst studies on the ring opening of tetrahydrofuran-dimethanol to 1,2,6-hexanetriol

The metal catalyzed hydrogenolysis of the biomass-derived THF-dimethanol to 1,2,6-hexanetriol using heterogeneous catalysts was investigated. Bimetallic Rh-Re catalysts (4 wt% Rh and a Re/Rh (mol. ratio of 0.5) on a silica support gave the best performance and 1,2,6-hexanetriol was obtained in 84% selectivity at 31% conversion (120 C, 80 bar, 4 h); the selectivity reaches a maximum of 92% at 80 C. The product distribution at prolonged reaction times or higher temperatures or both shows the formation of diols and mono-alcohols, indicating that the 1,2,6-hexanetriol is prone to subsequent hydrodeoxygenation reactions. Different silica supports were investigated and optimal results were obtained with an amorphous silica featuring an intermediate surface area and an average mesopore size of about 6 nm. TPR and XPS surface analysis support the presence of mixed Rh and Re particles. The redox Reδ+/ReTotal surface ratio correlates with the conversion in a volcano type dependency. Both gas phase as well as Rh200Re1OH cluster DFT calculations support an acid-metal bifunctional mechanism and explain the products distribution. © 2013 Elsevier B.V. All rights reserved.

Stabilization of self-assembled alumina mesophases

An efficient route to stabilize alumina mesophases derived from evaporation-induced self-assembly is reported after investigating various aspects in-depth: influence of the solvent (EtOH, s-BuOH, and t-BuOH) on the textural and structural properties of the mesophases based on aluminum tri-sec-butoxide (ATSB), synthesis reproducibility, role of nonvolatile acids, and the crystallization and thermal stability of the crystalline counterparts. Mesophase specific surface area and pore uniformity depend notably on the solvent; s-BuOH yields the highest surface area and pore uniformity. The optimal mesophase synthesis is reproducible with standard deviations in the textural parameters below 5%. The most pore-uniform mesophases from the three solvents were thermally activated at 1023 K to crystallize them into γ-alumina. The s-BuOH mesophase is remarkably thermally stable, retaining the mesoscopic wormhole order with 300 m2/g (0.45 cm3/g) and an increased acidic site density. These features are not obtained with EtOH or t-BuOH, where agglomerated γ-Al2O3 crystallites are formed with lower surface areas and broader pore size distributions. This was rationalized by the increase of the hydrolysis rate using EtOH and t-BuOH. t-BuOH dehydrates under the synthesis conditions or reacts with HCl, situations that increase the water concentration and rate of hydrolysis. It was found that EtOH exchanges rapidly, producing a highly reactive Al-ethoxide, thus enhancing the hydrolysis rate as well. Particle heterogeneity with random packing of fibrous and wormhole morphologies, attributed to the high hydrolysis rate, was observed for mesophases derived from both solvents. Such a low particle coordination favors coarsening with enlargement of the pore size distribution upon thermal treatment, explaining the lower thermal stability. Controlled hydrolysis and formation of low-polymerized Al species in s-BuOH are possibly responsible for the adequate assembly onto the surfactant. This was verified by the formation of a regular distribution of relatively size-uniform nanoparticles in the mesophase; high particle coordination prevents coarsening, favors densification, and maintains a relatively uniform pore size distribution upon thermal treatment. The acid removal in the evaporation is another key factor to promote network condensation in this route. © 2013 American Chemical Society.
