Developing nonprecious metal-based electrocatalysts with exceptional activity and durability for water electrolysis remains a significant challenge. Herein, we report a highly efficient bifunctional electrocatalyst composed of sulfur-doped vanadium metal-organic frameworks (S@V-MOF) integrated with multiwalled carbon nanotubes (MWCNTs) to promote the synergistic effect between S@V-MOF and MWCNTs and modulate the electronic structure of the catalyst, which eventually enhanced its electrocatalytic performance. The S@V-MOF/MWCNT catalyst loaded at the Ni foam electrode exhibits remarkable activity for both the hydrogen evolution reaction (HER) in acidic media and oxygen evolution reaction (OER) in alkaline media, requiring overpotentials of 48 and 227 mV, respectively, to reach a current density of 10 mA cm.

The COVID-19 pandemic, caused by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), is in its sixth year and is being maintained by the inability of current spike-alone-based COVID-19 vaccines to prevent transmission leading to the continuous emergence of variants and sub-variants of concern (VOCs). This underscores the critical need for next-generation broad-spectrum pan-Coronavirus vaccines (pan-CoV vaccine) to break this cycle and end the pandemic. The development of a pan-CoV vaccine offering protection against a wide array of VOCs requires two key elements: (1) identifying protective antigens that are highly conserved between passed, current, and future VOCs; and (2) developing a safe and efficient antigen delivery system for induction of broad-based and long-lasting B- and T-cell immunity.

Deep eutectic solvent (DES)-based conductive hydrogels have attracted great interest in the building of flexible electronic devices that can be used to replace conventional temperature-intolerant hydrogels and expensive ionic liquid gels. However, current DES-based conductive hydrogels obtained have limited mechanical strength, high hysteresis, and poor microdeformation sensitivity of the assembled sensors. In this work, a rubber-like conductive hydrogel based on -acryloylglycinamide (NAGA) and DES (acetylcholine chloride/acrylamide) has been synthesized by a one-step method.

The adhesion of raindrops on car rearview mirrors poses a significant threat to traffic safety due to the resulting blurred vision. Transparent superhydrophobic coatings have emerged as a potential solution to this problem. However, the development of transparent superhydrophobic coatings is often hampered by complex preparation procedures, high costs, and limited substrate compatibility, rendering them unsuitable for practical applications.

Due to the high configuration entropy, unique atomic arrangement, and electronic structures, high-entropy materials are being actively pursued as bifunctional catalysts for both the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) in rechargeable zinc-air batteries (ZABs). However, a relevant strategy to enhance the catalytic activity of high-entropy materials is still lacking. Herein, a hole doping strategy has been employed to enable the high-entropy perovskite La(CrMnFeCoNi)O to effectively catalyze the ORR and OER.
