For the first time,scientists catch water molecules passing the proton baton
first time scientists water molecules proton baton
2016/12/13
Water conducts electricity, but the process by which this familiar fluid passes along positive charges has puzzled scientists for decades.But in a paper published in the Dec. 2 issue of the ...
Clustering, Reorientation Dynamics, and Proton Transfer In Glassy Oligomeric Solids
imidazole proton transfer reorientation
2014/11/20
We have modelled structures and dynamics of hydrogen bond networks that form from imidazoles tethered to oligomeric aliphatic backbones in crystalline and glassy phases. We have studied the behavior o...
Performance evaluation of platinum-based catalysts for the development of proton exchange membrane fuel cells
Methanol catalysts cyclic voltammetry PEM fuel cell
2010/10/15
Platinum-based catalysts are considered the most efficient catalysts for triggering electrochemical reactions in proton exchange membrane (PEM) fuel cells. In the present study, commercial catalysts c...
Shape coexistence of high-spin isomeric states in proton-rich A~190 nuclei
high-spin isomer shape coexistence configuration-constrained calculation
2009/8/14
High-spin isomeric states in proton-rich A~190 nuclei have been investigated using configuration-constrained calculations of potential-energy surfaces. The calculations reproduce reasonably the experi...
Proton Conduction in PVPA --Benzimidazole Hybrid Electrolytes
Poly(vinylphosphonic acid) benzimidazole proton conductivity thermal properties
2010/4/20
Proton conducting properties of benzimidazole (BnIm) doped poly(vinylphosphonic acid) (PVPA) were studied. The doping ratio, x, which is the number of moles of BnIm per mole of polymer repeat unit, va...
Anhydrous Proton Conductive Polystyrene Sulfonic Acid Membranes
Polystyrene sulfonic acid benzimidazole thermal properties proton conductivity
2010/4/20
A novel anhydrous proton conducting polymer electrolyte based on polystyrene sulfonic acid, PSSA and benzimidazole (BnIm) was synthesized. The PSSA-BnIm interactions were studied by FT-IR. The thermal...
Application of Proton Conducting Polymer Electrolytes to Electrochromic Devices
Electrochromic Window Poly(diallyldimethylammonium dihydrogenphosphate) Proton Conductor
2010/4/22
Electrochromic display devices have been fabricated using Polydiallyldimethylammonium dihydrogenphosphate (PAMA+ H2PO4-) blended with H3PO4 as the electrolyte and WO3 as the electrochromic film. The W...
