Glass transition temperatures for sucrose, trehalose, and water have been determined by numerous studies in the past. Literature values appear to be fairly scattered and compromise the applicability of the Gordon–Taylor equation for aqueous solutions. This work deals with the effect of the sample history and heating process on the values. Consistent estimates for the glass transition temperature of both disaccharides in aqueous solution can be made from these observations.
Improved Critical Compilations of Selected Atomic Transition Probabilities for Neutral and Singly Ionized Carbon and Nitrogen36(2007); http://dx.doi.org/10.1063/1.2740642View Description Hide Description
We have undertaken new critical assessments and tabulations of the transition probabilities for important lines of neutral and singly ionized carbon and nitrogen. Our updates primarily address the persistent lower transitions as well as a greatly expanded number of forbidden lines (M1, M2, and E2 lines). For these transitions, sophisticated multiconfiguration Hartree–Fock calculations have been recently carried out, which have yielded data considerably improved and often appreciably different from our 1996 NIST compilation.

This review serves to update previously published evaluations of equilibrium constants and enthalpy changes for enzyme-catalyzed reactions. For each reaction, the following information is given: the reference for the data, the reaction studied, the name of the enzyme used and its Enzyme Commission number, the method of measurement, the conditions of measurement [temperature, , ionic strength, and the buffer(s) and cofactor(s) used], the data and their evaluation, and, sometimes, commentary on the data and on any corrections which have been applied to the data or any calculations for which the data have been used. The review contains data from 119 references which have been examined and evaluated. Chemical Abstract Service registry numbers are given for the substances involved in these various reactions. There is also a cross reference between the substances and the Enzyme Commission numbers of the enzymes used to catalyze the reactions in which the substances participate.

Recommended liquid-liquid equilibrium (LLE) data for 12 binary ether-water systems have been obtained after the critical evaluation of all data (168 data sets) reported for 17 systems in the open literature up to the end of 2006. An equation for the prediction of the ether solubilities in water was developed. The predicted ether solubilities were used for the calculation of watersolubility in the ether-rich phase. The LLE calculations were done with the equation of state appended with a chemical term (EoSC) proposed by Góral [Fluid Phase Equilib.118, 27 (1996)]. The recommended data are presented in the form of individual tables with references. Using these recommended data, predictive ability has been tested for several UNIFAC and ASOG group-contribution methods.

This volume presents the solubility of inorganic compounds of actinides except for carbonates, which are included in Volume 74 of this series, and nitrates, which are covered in Volume 55. Also included are solubility data of compounds such as organosulfates, phosphates, and arsenates, which are not covered in Volume 74. The predominant part of this volume covers solubility data of thorium,uranium, neptunium, and plutonium compounds. Fewer data have been published for americium compounds and very few for compounds of actinium, protactinium, and transamericium elements. The literature has been covered up to the end of 2004. Documents which remained unavailable to the editor, and could not be included in the volume are listed in the Appendix. For some compounds it was not possible to show the Chemical Abstracts registry numbers since these have not been assigned.
