Thermal Behavior of Iron Arsenides Under Non-Oxidizing Conditions.
Fe2As has been studied in situ by synchrotron powder X-ray diffraction (PXRD) over the range of temperatures 25-850 °C and under a neutral atmosphere to understand its thermal behavior, which is potentially important for gold...
Route to high-energy density polymeric nitrogen t-N via He-N compounds.

A scaling law for distinct electrocaloric cooling performance in low-dimensional organic, relaxor and anti-ferroelectrics.
Electrocaloric (EC) materials show promise in eco-friendly solid-state refrigeration and integrable on-chip thermal management. While direct measurement of EC thin-films still remains challenging, a generic theoretical framework...
Pressure-Induced Superionicity of H- in Hypervalent Sodium Silicon Hydrides.
Tianxiao Liang, Zihan Zhang, Hongyu Yu, Tian Cui, Xiaolei Feng, Chris J Pickard, Defang Duan, Simon AT Redfern
Jul 23, 2021
Superionic states simultaneously exhibit properties of a fluid and a solid. Proton (H+) superionicity in ice, H3O, He-H2O, and He-NH3 compounds is well-studied. However, hydride (H-) superionicity in H-rich compounds is rare...

Design of Metal-Free Polymer Carbon Dots
Songyuan Tao, Siyu Lu, Yijia Geng, Shoujun Zhu, Simon AT Redfern, Yubin Song, Tanglue Feng, Weiqing Xu, Bai Yang
Mar 28, 2018
Polymer carbon dots (PCDs) are proposed as a new class of room-temperature phosphorescence (RTP) materials. The abundant energy levels in PCDs increase the probability of intersystem crossing (ISC) and their covalently...
Selecting Rotation Constants on SIMON-Type Ciphers
In 2013, a lightweight block cipher SIMON is proposed by NSA. This paper tries to investigate this design criterion in terms of resisting against impossible differential cryptanalysis. On one hand, starting from all the possible...
