Cathode Materials for Proton Exchange Membrane Fuel Cells: From Metal and Metal Composite Catalysts to Carbon‐Supported Hybrids in Oxygen Reduction Reaction

ChemElectroChem, Volume 12, Issue 16, August 20, 2025.
This review highlights recent progress in the development of electrocatalysts for the oxygen reduction reaction in proton exchange membrane fuel cells (PEMFCs). Particular focus is given to structure–activity relationships, active site identification, and the role of noble and non‐noble metals, with insights into synthetic strategies and performance in

Exact solution of the zero-range process: fundamental diagram of the corresponding exclusion process

, 2009
In this paper, we propose a general way of computing expectation values in the zero-range process, using an exact form of the partition function. As an example, we provide the fundamental diagram (the flux-density plot) of the asymmetric exclusion ...

Collective traffic-like movement of ants on a trail: dynamical phases and phase transitions

, 2004
The traffic-like collective movement of ants on a trail can be described by a stochastic cellular automaton model. We have earlier investigated its unusual flow-density relation by using various mean field approximations and computer simulations. In this

Facile Synthesis of Nanolayered Manganese Oxide for the Efficient and Selective Removal of Strontium(II) from Nuclear Wastewater

Advanced Science, Volume 12, Issue 30, August 14, 2025.
A novel nanolayered manganese oxide material (Na‐NLMO) is prepared using a rapid and straightforward method for efficient adsorption of Sr(II) in both simulated waste liquid and natural water systems. Its excellent adsorption performance of Na‐NLMO could be attributed to the accessible layered structure and negatively charged framework.

Enhanced ZRP Protocol for Mobile Ad-hoc Networks

International Journal of Wireless & Mobile Networks, 2011
Mobile Adhoc Network(MANET) is the collection of independent mobile nodes that can communicate to each other via radio waves. The mobile nodes that are in radio range of each other can directly communicate, whereas others need the aid of intermediate nodes to route their packets.

Nonequilibrium phase transition in a non integrable zero-range process

, 2006
The present work is an endeavour to determine analytically features of the stationary measure of a non-integrable zero-range process, and to investigate the possible existence of phase transitions for such a nonequilibrium model.
