Freestanding VS₂–sulfur hybrid cathode featuring a dual redox mechanism for high-loading and lean-electrolyte lithium–sulfur batteries

Hafiz Khurram Shahzad, Sasan Ghashghaie, Mohsen Tamtaji, Iftikhar Hussain et autres

The practical implementation of lithium‑sulfur batteries (LSBs) has long been hindered by several interlinked challenges, including low sulfur utilization, polysulfide shuttling, volumetric expansion, and high electrolyte-to‑sulfur (E/S) ratios. To address these limitations from a practical viability perspective, we designed a hybrid cathode …

Acceleration of spheroidisation in a medium carbon steel processed by equal channel angular pressing

L.W. Ma, Kenong Xia

A medium carbon alloy steel was processed using equal channel angular pressing (ECAP) with a view to accelerating the softening process during subsequent annealing. The steel was pressed at 600°C for up to four passes. The original well-aligned lamellar cementite became bent …

Three-dimensional bioprinting of artificial ovaries by an extrusion-based method using gelatin-methacryloyl bioink

Tong Wu, Y. Y. Gao, Jiansheng Su, Xiaoning Tang et autres

The aim of this study was to design and fabricate a three-dimensional (3D) printed artificial ovary. We first compared the printability of gelatin-methacryloyl (GelMA), alginate and GelMA–alginate bioinks, of which GelMA was selected for further investigation. The swelling properties, degradation kinetics and …
