High temperature thermoelectric efficiency in Ba8Ga16Ge30 [PDF]

open access: yes, 2008
The high thermoelectric figure of merit (zT) of Ba8Ga16Ge30 makes it one of the best n-type materials for thermoelectric power generation. Here, we describe the synthesis and characterization of a Czochralski pulled single crystal of Ba8Ga16Ge30 and ...

High‐Efficiency CO2 Electrolysis Enabled by Interface‐Engineered Composite Electrolytes in Ni‐Based SOEC

open access: yesAdvanced Science, Volume 13, Issue 14, 9 March 2026.
This study addresses the critical issue of delamination between YSZ and GDC electrolytes in SOECs, which is caused by Thermal deformation disparity. A novel YSZ‐GDC composite interlayer, fabricated using a simple dip‐coating method, is introduced to solve this problem. This layer effectively suppresses delamination by mitigating thermal stress.

Method to Evaluate the Kinetics of Bainite Transformation in Low-Temperature Nanobainitic Steel Using Thermal Dilatation Curve Analysis

open access: yesMetals, 2017
The aim of this work was to develop a method to evaluate the kinetics of bainite transformation by theoretical deduction and thermal dilatation curve analysis. A Gleeble-3500 thermomechanical simulator and dilatometer (DIL805A) were employed to study the

Beyond Imperfect Match: Silicon/Graphite Hybrid Anodes for High‐Energy–Density Lithium‐Ion Batteries

open access: yesAdvanced Energy Materials, Volume 16, Issue 10, 11 March 2026.
Silicon/graphite (Si/Gr) hybrid anodes are limited by Si's large volume change and mismatch with Gr. This review offers mechanistic insights into imperfectly matched Si/Gr hybrid anodes, elucidating heterogeneous lithiation behavior and interfacial failure pathways, and thereby informing the design of durable, high‐energy–density lithium‐ion batteries.

Spectral Evidence for Emergent Order in Ba$_{1-x}$Na$_x$Fe$_2$As$_2$

open access: yes, 2018
We report an angle-resolved photoemission spectroscopy study of the iron-based superconductor family, Ba$_{1-x}$Na$_x$Fe$_2$As$_2$. This system harbors the recently discovered double-Q magnetic order appearing in a reentrant C$_4$ phase deep within the ...

Low-temperature structural investigations of the frustrated quantum antiferromagnets Cs2CuCl(4-x)Br(x) [PDF]

open access: yes, 2014
Powder X-ray diffraction (PXRD) and single-crystal neutron scattering were used to study in detail the structural properties of the Cs2CuCl(4-x)Br(x) series, good realizations of layered triangular antiferromagnets.

Entropy Profiling of Hard Carbon/Na Metal Cells with Stepwise Temperature Changes: Influence of the Sodiation Kinetics on the Cell Voltage Response

open access: yesBatteries &Supercaps, Volume 9, Issue 3, March 2026.
The cell reaction entropy of hard carbon/Na metal cells at different states of charge was derived from the cell voltage variation caused by stepwise temperature changes. The magnitude of the cell reaction entropy indicated complete desolvation of the sodium ions upon the sodiation of hard carbon.
