The classic Shilov-Dukhin theory of the low frequency dielectric dispersion of colloidal suspensions in binary electrolyte solutions [ Shilov , V. N. ; Dukhin , S. S. , Colloid J. 1970 , 32 , 245. ; Dukhin , S. S. ; Shilov , V. N. Dielectric Phenomena and the Double Layer in Disperse Systems and Polyelectrolytes ; Wiley : New York , 1974 ] was developed for the frequency range corresponding to the concentration polarization phenomenon: up to a few megahertz. While a few extensions to a broad frequency range including the Maxwell-Wagner-O'Konski dispersion exist, they all consist of modifications of the final results of the theory rather than modifications of its hypothesis, extending their validity to high frequencies. In this work we avoid this artificial process by providing a high frequency extension fully from within the theory.

People appreciate members of their in-group, and they cooperate with them-tendencies we refer to as in-group love. Being a member of a minority (vs. majority) is a common experience that varies both between groups in a context and within a group between contexts, but how does it affect in-group love? Across six studies, we examined when and why .

The insulating transition metal nitride CaCrN consists of sheets of triangular [CrN] units with symmetry that are connected via quasi-1D zigzag chains. Due to strong covalency between Cr and N, Cr ions are unusually low-spin, and = 1/2. Magnetic susceptibility measurements reveal dominant quasi-1D spin correlations with very large nearest-neighbor antiferromagnetic exchange = 340 K and yet no sign of magnetic order down to = 0.

Mononuclear Fe enzymes such as heme-containing cytochrome P450 enzymes catalyze a variety of C-H activation reactions under ambient conditions, and they represent an attractive platform for engineering reactivity through changes to the native enzyme. Using density functional theory, we study both native Fe and non-native group 8 (Ru, Os) and group 9 (Ir) metal centers in an active site model of P450. We quantify how changing the metal changes spin state preferences throughout the catalytic cycle.

Multicomponent reactions have long been recognized as some of the most versatile tools in organic chemistry, with extensive applications in biomedical science and the pharmaceutical industry. In this study, we explored the potential of the Passerini reaction by designing and synthesizing new low molecular mass gelators that can serve as novel formulations for prolonged anesthesia. These gelators address critical issues like poor solubility, low bioavailability, and short plasma half-life, all of which hinder therapeutic efficacy.
