A combined "electrochemical-frustrated Lewis pair" approach to hydrogen activation: surface catalytic effects at platinum electrodes [PDF]

, 2014
Herein, we extend our “combined electrochemical–frustrated Lewis pair” approach to include Pt electrode surfaces for the first time. We found that the voltammetric response of an electrochemical–frustrated Lewis pair (FLP) system involving the B(C6F5)3 ...

An extremely rapid, convenient and mild coal desulfurization new process: Sodium borohydride reduction

Fuel Processing Technology, 2010
Abstract The present work describes the desulfurization of coal using mildly reductive method. Both a Yanzhou and a Yanshan coal (referred to as YZ and YS coal, respectively), were treated in an aqueous media employing sodium borohydride (NaBH 4 ) as reducing agent, which is a well known hydrogen storage.

Cell-wall polysaccharides play an important role in decay resistance of Sphagnum and actively depressed decomposition in vitro [PDF]

, 2011
Sphagnum-dominated peatlands head the list of ecosystems with the largest known reservoirs of organic carbon (C). The bulk of this C is stored in decomposition-resistant litter of one bryophyte genus: Sphagnum. Understanding how Sphagnum litter chemistry

Development of polymeric hollow fiber membranes containing catalytic metal nanoparticules. [PDF]

, 2010
Metal nanoparticles (MNPs) have unique physico-chemical properties advantageous for catalytic applications which differ from bulk material. However, the main drawback of MNPs is their insufficient stability due to a high trend for aggregation.
