Molecular dynamics of a grid-mounted molecular dipolar rotor in a rotating electric field

Classical molecular dynamics is applied to the rotation of a dipolar molecular rotor mounted on a square grid and driven by rotating electric field E(ν) at T ≃ 150 K. The rotor is a complex of Re with two substituted o-phenanthrolines, one positively and one negatively charged, attached to an axial position of Rh\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \setlength{\oddsidemargin}{-69pt} \begin{document} \begin{equation*}{\mathrm{_{2}^{4+}}}\end{equation*}\end{document} in a [2]staffanedicarboxylate grid through 2-(3-cyanobicyclo[1.1.1]pent-1-yl)malonic dialdehyde. Four regimes are characterized by a, the average lag per turn: (i) synchronous (a < 1/e) at E(ν) = |E(ν)| > Ec(ν) [Ec(ν) is the critical field strength], (ii) asynchronous (1/e < a < 1) at Ec(ν) > E(ν) > Ebo(ν) > kT/μ, [Ebo(ν) is the break-off field strength], (iii) random driven (a ≃ 1) at Ebo(ν) > E(ν) > kT/μ, and (iv) random thermal (a ≃ 1) at kT/μ > E(ν). A fifth regime, (v) strongly hindered, W > kT, Eμ, (W is the rotational barrier), has not been examined. We find Ebo(ν)/kVcm−1 ≃ (kT/μ)/kVcm−1 + 0.13(ν/GHz)1.9 and Ec(ν)/kVcm−1 ≃ (2.3kT/μ)/kVcm−1 + 0.87(ν/GHz)1.6. For ν > 40 GHz, the rotor behaves as a macroscopic body with a friction constant proportional to frequency, η/eVps ≃ 1.14 ν/THz, and for ν < 20 GHz, it exhibits a uniquely molecular behavior.

Stabilization of APIs and nutraceuticals through cocrystallization and molecular confinement

Cocrystallization of the molecule of interest could be a smart and dainty way to tune solubility properties of solid phases leaving the molecule chemically unchanged, hence it is widely investigated by companies and by solid state scientists. Despite of this extremely high interest towards cocrystallization no particular emphasis has been paid to using it as a means to stabilize liquid molecules. In this work we define a benchmark of relevant molecules for human health that have been combined with suitable partners according to crystal engineering methods in order to obtain cocrystals. Solubility properties in different solvents of cocrystals new solid phases have been tested and compared to the properties of the drugs. A further approach to deal with volatile compounds is molecular confinement inside molecular scaffold. Nowadays metal organic frameworks (MOFs) are studied in many fields ranging from catalysis to trapping or storage of gases, such as hydrogen, methane, CO2 thanks to their extremely high porosity. Our goal is to confine liquid guests of biological relevance inside MOF pores, monitoring via X-ray diffraction, spectroscopy and thermal analysis the stabilization of the molecule of interest inside the cavities.

Illinois Phosphorus Effluent Limits: Minimizing the Impacts Through the Use of Non-point Controls at the Springbrook Water Reclamation Center in Naperville, Illinois

Phosphorus pollution is a major concern in Illinois. Excessive amounts of phosphorus can be detrimental to water bodies. To help control phosphorus, the Illinois Pollution Control Board has proposed phosphorus limits on wastewater treatment facility discharges. If enacted, these limits will have negative impacts on the Springbrook Water Reclamation Center in Naperville, Illinois. To minimize these impacts, Naperville can utilize various non-point controls recommended in this paper to decrease the amount of phosphorus entering into the DuPage River and the Springbrook Water Reclamation Center. While these controls will not reduce levels low enough to totally satisfy limits on phosphorus discharges, they will significantly reduce the treatment costs Naperville will need to expend to meet them and be more environmentally effective.

A report to the Illinois General Assembly pursuant to the Illinois Energy Assistance Act 305 ILCS 20 : Supplemental Low-Income Energy Assistance Fund expenditures : January 1998 through June 2003.

The Supplemental Low Income Energy Assistance Fund is the depository for energy assistance charges collected by utilities and participating municipal utilities and electric cooperatives authorized by the Electric Customer Choice and Rate Relief Act of 1997 (220 ILCS 5). The energy assistance charges provided a nonfederal funding stream to the Department for use in providing energy related assistance to low-income households under the Illinois Low Income Home Energy Assistance and Illinois Home Weatherization (LIHEAP) Programs. Since the changes were imposed in January of 1998, $406,683,769 has been deposited into the Fund through December 2003. Of this amount, the Department has spent $326,137,510 to provide energy assistance to 802,091 households; $33,845,784 to weatherize 6,584 homes; and $32,570,739 to cover administrative expenses.

Assessment of retail and wholesale market competition in the Illinois electric industry /

In this report, the Commission examines developments relevant to the competitiveness of the retail and wholesale markets. In the retail market, two key indicators of activity are examined: The first indicator is the rate of customer switching from bundled services to "delivery services." Customers taking delivery services are either purchasing power and energy from ARES or are purchasing power and energy from the host utility on an "unbundled" basis under the utility's delivery services tariffs. Currently, bundled power sales mainly consist of sales to customers under the Sec. 16-110 "Power Purchase Option" (PPO). The second indicator of retail activity presented in this report is the number of suppliers active in the State's nine service territories.
