Synergistic W and V Doping Induce Defects and Thus a High Catalytic Surface Area in MoS2 for the Hydrogen Evolution Reaction

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
Double doping with V and W of hydrothermal microwave‐grown MoS2 enhances the density of structural defects. It improves the ECSA and shifts the surface chemistry to an oxysulfide‐rich environment. The resulting VW‐doped MoS2 nanoflowers thus demonstrate robust electrocatalysis of hydrogen evolution.

Studies on the Nutritional, Functional, Textural, and Sensory Characteristics of Finger and Barnyard Millet‐Incorporated Nuggets

open access: yesFood Chemistry International, EarlyView.
The graphic illustrates the development of nuggets traditionally known as “wari” prepared with whole green grams and composite flour barnyard millet var. (PRJ‐1) and finger millet var. (VL‐M‐380) in a 1:1 ratio. The addition of millet significantly improved the nutritional value of nuggets, providing higher levels of protein, carbohydrates, fiber ...
