Corrosion-resistant cobalt phosphide electrocatalysts for salinity tolerance hydrogen evolution

Nature Communications, 2023
Seawater electrolysis is a viable method for producing hydrogen on a large scale and low-cost. However, the catalyst activity during the seawater splitting process will dramatically degrade as salt concentrations increasing.

Mitigating the Effects of Maternal Loss on Harbour Seal Pups in Captive Care

Animals
Stranded newborn “orphan” harbour seal pups entering captive care are often maintained for some weeks in isolation, mainly as a precaution against the spread of infection. However, this practice raises concerns for the welfare and normal socialisation of

High-Throughput Calculation of Interlayer van der Waals Forces Validated with Experimental Measurements

Research, 2022
Interlayer van der Waals interactions play an important role in two-dimensional (2D) materials on various occasions. The interlayer binding force is often directly measured and is considered more closely related to the exfoliation condition.

Tumor‐stromal crosstalk and macrophage enrichment are associated with chemotherapy response in bladder cancer

FEBS Open Bio, EarlyView.
Chemoresistance in bladder cancer: Macrophage recruitment associated with CXCL1, CXCL5 and CXCL8 expression is characteristic of Gemcitabine/Cisplatin (Gem/Cis) Non‐Responder tumors (right side) while Responder tumors did not show substantial tumor‐stromal crosstalk (left side). All biological icons are attributed to Bioicons: carcinoma, cancerous‐cell‐
