Simultaneously Engineering the Amorphous Phase and Branch Morphology of High‐Entropy Alloy Nanomaterials for Enhanced Ethylene Glycol Oxidation

open access: yesAdvanced Materials, EarlyView.
Amorphous PdCuNiCoFe high‐entropy alloy nanobranches were developed through a versatile wet‐chemical synthetic strategy enabling simultaneous control of composition, phase, and morphology. The resulting amorphous PdCuNiCoFe nanobranches exhibit outstanding electrocatalytic performances for ethylene glycol oxidation (EGOR), delivering high selectivity ...

Advanced Design for Weakly Coupled Resonators by Automatic Active Optimization

open access: yesAdvanced Materials Technologies, EarlyView.
An Automatic Active Optimization (AAO) strategy integrates machine learning predictors and genetic algorithms in a closed‐loop workflow. By iteratively expanding its dataset with new discoveries, AAO overcomes the limits of conventional methods. This approach finds superior microstructural designs beyond the initial sample space. We demonstrate this on

Nuclear coalescence from correlation functions

open access: yes, 2019
We derive a simple formula relating the cross section for light cluster production (defined via a coalescence factor) to the two-proton correlation function measured in heavy-ion collisions.

Passive Shape‐Adaptive Fluidic Interface for Enhanced Skin‐Sensor Coupling in Wearable Devices

open access: yesAdvanced Materials Technologies, EarlyView.
This study presents a passive fluidic interface for wearable biosensors that adapts to static and dynamic body shape changes to maintain consistent skin contact. Flexible, fluid‐filled pouches redistribute pressure from high‐load areas to regions requiring improved contact, enhancing signal quality and comfort in a compact, low‐energy design for ...

Partial normalizations of coxeter arrangements and discriminants [PDF]

open access: yes, 2011
We study natural partial normalization spaces of Coxeter arrangements and discriminants and relate their geometry to representation theory. The underlying ring structures arise from Dubrovin’s Frobenius manifold structure which is lifted (without unit)

Understanding the Structural Scaling Relations of Early-Type Galaxies [PDF]

open access: yes, 2014
We use a large suite of hydrodynamical simulations of binary galaxy mergers to construct and calibrate a physical prescription for computing the effective radii and velocity dispersions of spheroids.

Tunable Extraordinary Optical Transmission in the Long‐Wavelength Infrared Range Using Electrostatic MEMS Actuation

open access: yesAdvanced Materials Technologies, EarlyView.
A MEMS‐integrated metamaterial filter enables continuous, low‐voltage spectral tuning in the long‐wavelength infrared (LWIR). The device employs extraordinary optical transmission in a dual suspended metasurface stack, where electrostatic actuation precisely controls the intermembrane air gap.

Mongolian-Chinese economic cooperation as an important factor in NEA economic regionalism

open access: yesОлон улс судлал, 2007
Mongolian-Chinese economic and trade relations went through a dramatic expansion in fifteen years from frozen relations during the Sino- Soviet cold war to all round partnership during 1990-2006.

On the normalization of a priority vector associated with a reciprocal relation. [PDF]

open access: yes
In this paper we show that the widely used normalization constraint SUM(i=1,n) wi = 1 does not apply to the priority vectors associated with reciprocal relations, whenever additive transitivity is involved.

Non-relativistic bound states in a finite volume

open access: yes, 2011
We derive general results for the mass shift of bound states with angular momentum l >= 1 in a periodic cubic box in two and three spatial dimensions. Our results have applications to lattice simulations of hadronic molecules, halo nuclei, and Feshbach ...
