Vacancy engineering of TiO with low Pt content for efficient hydrogen generation.

Titanium dioxide (TiO) supported with low content precious metals is a crucial strategy for attaining optimal performance in the hydrogen evolution reaction (HER), but the synthesis route is usually energy-consuming and complicated. In this work, an ultra-fast (70 s) and simple microwave strategy is proposed to prepare black TiO with low load Pt (Pt/TiO) for the HER. The created oxygen vacancies facilitate electron transfer and enhance the metal-support interactions.

A hybridization chain reaction-based electrochemical sensor for rapid detection of respiratory pathogens.

Respiratory viral infections continue to pose a significant challenge to global public health. Electrochemical nucleic acid sensors, with their high sensitivity and ease of miniaturization, demonstrate great diagnostic potential.

Research Progress on Electrode Structure of Transparent Supercapacitor.

Supercapacitors are a crucial part of electronic equipment, the development of smart devices such as LEDs, touchscreens, and portable electronics, prompt supercapacitors with new features such as transparency and flexibility. The construction of transparent electrodes includes two main ways: i) electrode material is intrinsically transparent, and ii) networks with controllable distribution of voids or discontinuous regions (multi-gap network structures) increase the transmittance to achieve transparency. Few types of transparent materials, high costs, and complicated preparation limit the development of transparent supercapacitor (TSCs).

Characteristics of intracellular/extracellular antibiotic resistance genes and microbial community in sludge compost under sulfadiazine stress.

The accumulation of emerging antibiotics in sewage sludge, which serves as a repository for antibiotic resistance genes (ARGs) and mobile genetic elements (MGEs), is raising growing concern.

However, the impact of sulfadiazine (SDZ) on iARGs and eARGs, and the mechanisms involved in the composting process remain under further investigation.

Mining robust in situ phosphorus-accumulating organisms via single-cell RACS-Culture for rational ecosystem engineering.

Rational engineering of ecosystems is often hindered by the inability to rapidly identify, profile, culture and apply the microbes that underlie target metabolic activity in situ. Here, we developed an In-situ Metabolism driven Sorting, Culture and Augmentation (IMSCA) strategy via Raman-activated Cell Sorting coupled to single-cell culture (scRACS-Culture), and demonstrated it through the mining of in situ polyphosphate-accumulating organisms (PAOs) for wastewater treatment. Single-cell polyphosphate-accumulating activities in situ were quantitatively assessed directly from environmental samples via the polyphosphate band in Raman spectrum, revealing their remarkable distinction from those from pure cultures.
