Electrokinetically enhanced pipe flow of coal-water suspensions using a nonintrusive helical anode-cathode geometry. [PDF]
, 2007 It has been experimentally demonstrated that the application of electrokinetic techniques in the continuous flow of coal-water suspensions within a helical anode-cathode pipe geometry effectively causes a significant reduction in the wall shear stress ...

Liquid Bismuth Catalyst Enables High‐CO‐Selectivity in CO2 Hydrogenation
Advanced Science, EarlyView.This work introduces a dynamic liquid bismuth catalyst for efficient CO2‐to‐syngas conversion. Stabilized molten Bi nanodroplets on a defective VOx support enable a reversible Bi3+/Bi0 redox cycle at moderate temperatures. Mechanistic insights reveal that Ni‐Bi dual sites synergistically activate H2 and cleave CO2, leading to high CO selectivity ...

Why Are Some Public Officials More Corrupt Than Others? [PDF]
, 2005 Using detailed Peruvian data measuring bribery, I assess which types of public official are most corrupt and why. I distinguish between the bribery rate and the size of bribes received, and seek to explain the variation in each across public institutions.

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Water is a fundamental necessity for our existence, but its rapid contamination is causing devastating effects on the environment and health of living species worldwide. Adsorptive removal of pollutants is one of the popular water treatment techniques because of its simplicity, affordability, and the broad range of available adsorbents.
