Post-grafting preparation of large-pore mesoporous materials with localized high content titanium doping

A new post-grafting process, consisting of two steps of substrate preparation and sol - gel post-grafting, has been developed to prepare titanium-doped mesoporous SBA-15 material with a double-layered structure and locally concentrated titanium content at the inner pore surface. With this novel technique, the single phased and originally ordered mesostructures can be well conserved; in the conventional direct synthesis they can be partially damaged when the frameworks are doped with high content heteroatoms. Titanium species exist in an isolated, tetrahedral structure and are localized at the pore surface; this is beneficial to both reactant access and product release. Characterization with XRD, N-2 adsorption/desorption isotherms, HREM/ EDS, ICP, UV - Vis, and the newly developed UV - Raman spectroscopy confirm these results. Preliminary catalytic tests with the selective epoxidation of cyclohexene show good catalytic activity. Among them, sample TiSBA-15-10 with a Si : Ti molar ratio of 10 shows a TON value of 75 and a highest product ( epoxide) yield of 55%.

Gut microbiota modification: Another piece in the puzzle of the benefits of physical exercise in health?

Regular physical exercise provides many health benefits, protecting against the development of chronic diseases, and improving quality of life. Some of the mechanisms by which exercise provides these effects are the promotion of an anti-inflammatory state, reinforcement of the neuromuscular function, and activation of the hypothalamic–pituitary–adrenal (HPA) axis. Recently, it has been proposed that physical exercise is able to modify gut microbiota, and thus this could be another factor by which exercise promotes well-being, since gut microbiota appears to be closely related to health and disease. The purpose of this paper is to review the recent findings on gut microbiota modification by exercise, proposing several mechanisms by which physical exercise might cause changes in gut microbiota.

Rola Francji i Niemiec w procesie integracji europejskiej w latach 1992-2007

Francja i Niemcy przez stulecia walczyły o zdobycie władzy i przejęcie wpływów na kontynencie europejskim i traktowały siebie nawzajem jako największe zagrożenie. Jednak tragiczna pierwsza połowa XX wieku przyniosła z jednej strony pragnienie zapewnienia, iż okropności wojny już nigdy się nie powtórzą, a z drugiej strony poczucie, że nieodzowna jest zmiana dwustronnych stosunków panujących między Berlinem a Paryżem. Konieczność stworzenia przestrzeni wolności i współpracy doprowadziła niegdysiejszych wrogów do stworzenia idei integracji najważniejszych części gospodarki. Pomysł zjednoczenia krajów Europy Zachodniej przekształcił się w kolejnych latach w symbol zaangażowania francusko-niemieckiego. Dwie republiki stały się rdzeniem europejskiej współpracy i spiritus movens zmian politycznych, ekonomicznych i instytucjonalnych w powojennej Europie. Po upadku komunizmu w 1989 roku ich rola zyskała nowy wymiar w odmiennych warunkach geopolitycznych - od momentu podpisania Traktatu z Maastricht w 1992 roku francusko-niemiecki duet powiększył swe znaczenie i wpływ na politykę nowej Unii Europejskiej. Realizacja zapisów Traktatu z Maastricht i kolejnych dokumentów, w tym Traktatu z Lizbony, koncentracja na kwestiach reform instytucjonalnych, jak również przygotowania do wschodniego rozszerzenia UE mogą być rozpatrywane jedynie w odniesieniu do wspólnych działań prowadzonych przez nadreński tandem. Realizacja trzech filarów integracji: współpracy w wymiarze ekonomicznym i społecznym, wspólnej polityki zagranicznej i bezpieczeństwa, jak również współpracy policyjnej i sądowej w sprawach karnych, podkreślają znaczenie couple franco-allemand i zwracają uwagę na rolę lidera, jaką Paryż i Berlin odgrywają w dziedzinie integracji.

The Arab Spring as a Test of post-Lisbon Capabilities and Strategies of the European Union in North Africa

This study aims to present the conditions related to the European Union’s involvement in the Arab Spring, as well as examine the extent of this capability-based involvement in the first months of 2011 against the background of competence disputes between institutions and inter-governmental contentions. These considerations will be the basis for conclusions on the theoretical and practical viability of the European Union’s action in the region of North Africa, in terms of both interests defined in Brussels and representation of a jointly agreed position and undertaking practical actions in the international arena. These assumptions can facilitate a new perspective for the EU’s strategic approach framework in the region of North Africa.

O naruszaniu podstawowych zasad postępowania naukowego. “Wzgórze przeznaczenia archeologii” górą skandalu

„We are paying a high price for the increasingly unequivocal equation drawn between knowledge and science and ordinary market product. The ideal of perfectly unrestrained cognition, the true mother of science, is threatened by the mass drive towards practical use and application of knowledge, a looming departure into nothingness. Politicians and managers of scientific life are guilty of considerable contribution in corrupting respectable university structures, and thus undermining culture of science and scholarly ethics. (…). Acquisition of funds, sponsorship, media presence, popularisation or even striving for commercial gain are recognised by politicians and scientific consultants, but most of all they are accepted by the university management as objectives worthy of effort, not to say the foremost goals of science. University rectors are nowadays interested primarily in the amounts of acquired moneys. The outcomes of research thus financed is subject to virtually no control, nor does it arouse any interest, unless it turns out to be fit to be announced in the media as a sensation, thereby serving the ‘prestige’ of the university”.
