Polarizable Vanadium Dipoles Promote Water Dissociation on Vanadium‐Based Metal Organic Framework
Advanced Functional Materials, EarlyView.The polarization of unpaired V 3d electrons weakens the H─O bond to improve water dissociation by the dual Vδ+:O─H and Pλ−:H─O coupling hydrogen bonds formation and relaxation. P@V‐MOF electrocatalyst shows low overpotentials (94 mV in acid, 178 mV in neutral, and 77 mV in alkaline solutions) with excellent stability for effective overall water ...

Experimental analysis of noise reduction properties of sound absorbing foam [PDF]
, 2001 Plan BWood dust deposition had both positive and negative effects on the sound absorption properties of acoustical foam. Three layers of wood dust were deposited on acoustical foam in a 2.44 meter by 2.44 meter by 2.44 meter Plexiglas test chamber.

, 2014 The spin foam framework provides a way to define the dynamics of canonical loop quantum gravity in a spacetime covariant way, by using a path integral over histories of quantum states which can be interpreted as `quantum space-times'. This chapter provides a basic introduction to spin foams aimed principally at beginning graduate students and, where ...
