The basic features and most salient examples of flow-through chemical and biochemical sensors based on the integration of derivative analytical reactions, separation processes (dialysis, gas diffusion, sorption, liquid-liquid extraction) and detection (optical, electroanalytical, mass, thermal) are presented and discussed, and critically compared with those of probe-type sensors and conventiona...
متن کاملIntroductory lecture: nonadiabatic effects in chemical dynamics.
Recent progress in the theoretical treatment of electronically nonadiabatic processes is discussed. First we discuss the generalized Born-Oppenheimer approximation, which identifies a subset of strongly coupled states, and the relative advantages and disadvantages of adiabatic and diabatic representations of the coupled surfaces and their interactions are considered. Ab initio diabatic represen...

متن کاملHighs and lows in the peripheral vasculature.
In recent years, we have come a long way from categorizing all ankle-brachial indices (ABIs) above 0.90 as normal. Both borderline low and high ABIs present significant risk (1). In this issue of the Journal, Arain et al. (2) at the Mayo Clinic document the risk of a high ABI with the largest such study to date. The authors provide us with remarkable data, presented clearly and concisely, on pa...
