Porous Iridium Oxide Inverse Opal Catalysts Enable Efficient PEM Water Electrolysis

open access: yesAdvanced Materials, EarlyView.
Porous iridium‐based inverse opal (IrOx‐IO) structures are introduced as high‐performance, unsupported PEM‐WE anode catalysts. Their electrochemical behavior is analyzed through porosity/surface area tuning, voltage breakdown, and circuit modeling.

Structural-Phase Transformations of an fcc-Alloy During Thermal Cycling

open access: yesRussian Physics Journal, 2015
Using an intermetallic compound of the Ni–Al system as an example, it is shown by the Monte Carlo technique that the processes developed during thermal cycling in the course of structural phase transformations in FCCalloys are irreversible. As a result of a heating–cooling cycle, a certain hysteresis is observed, whose presence suggests an ...

Dynamic, Reconfigurable, and Hierarchical Biosynthetic Composites via Collagen Self‐Assembly within Highly Crowded Microgel Pastes

open access: yesAdvanced Materials, EarlyView.
A new approach to extracellular matrix‐mimetic, hierarchical biomaterials is presented. Soft gels composed of overpacked hydrogel microparticle arrays present a biomolecularly crowded environment permissive to the self‐assembly of collagen networks.

Searching for high magnetization density in bulk Fe: the new metastable Fe$_6$ phase

open access: yes, 2014
We report the discovery of a new allotrope of iron by first principles calculations. This phase has $Pmn2_1$ symmetry, a six-atom unit cell (hence the name Fe$_6$), and the highest magnetization density (M$_s$) among all known crystalline phases of iron.

High‐Performance Zero‐Gap Glycerol‐Fed Electrolyzer for C3 Chemicals and Hydrogen Production

open access: yesAdvanced Materials, EarlyView.
This work presents a dynamic, self‐regulating operation strategy that enables selective glycerol electrooxidation in the OER‐free regime, co‐producing C3 chemicals and hydrogen at cell voltages below 1.25 V. Voltage‐ and temperature‐resolved analyses define optimal operating conditions, achieving a sustained current density of 500 mA cm−2 at ∼1.21 V ...

Metastable cubic and tetragonal phases of transition metals predicted by density-functional theory

open access: yes, 2015
By means of density-functional calculations, we systematically investigated 24 transition metals for possible metastable phases in body-centered tetragonal structure (bct), including face-centered cubic (fcc) and body-centered cubic (bcc) geometries.
