Tuning interfacial charge transport Ti-O-Sn bonds for efficient CO conversion.

Chem Commun (Camb)

December 2024

Institute of Green Chemistry and Chemical Technology, School of Chemistry and Chemical Engineering, Jiangsu University, Zhenjiang 212013, P. R. China.

Here, the clever design of forming an ohmic contact between SnS and MXene can regulate interfacial electron transport through Ti-O-Sn chemical bonds. This fast directional charge transport kinetics is attributed to the built-in electric field formed by the ohmic contact. As expected, the photoreduction CO activity of the optimized SSTC-5 catalyst is 10.

Photobiomodulation (PBM), also known as low-level laser therapy, employs red or near-infrared light emitted from a laser or light-emitting diode for the treatment of various conditions. Transcranial PBM (tPBM) is a form of PBM that is delivered to the head to improve brain health, as tPBM enhances mitochondrial function, improves antioxidant responses, reduces inflammation, offers protection from apoptosis, improves blood flow, increases cellular energy production, and promotes neurogenesis and neuroplasticity. As such, tPBM holds promise as a treatment for stroke.

Laboratory for Marine Drugs and Bioproducts, Qingdao Marine Science and Technology Center, Qingdao, 266237, China; School of Medicine and Pharmacy, Ocean University of China, Qingdao, 266003, China. Electronic address:

Biosensors play a critical role in the diagnosis, treatment, and prognosis of diseases, with diverse applications ranging from molecular diagnostics to in vivo imaging. Conventional fluorescence-based biosensors, however, often suffer from aggregation-caused emission quenching (ACQ), limiting their effectiveness in high concentrations and complex environments. In contrast, the phenomenon of aggregation-induced emission (AIE) has emerged as a promising alternative, where luminescent materials exhibit strong emission in the aggregated state with good photostability, biocompatibility, large Stokes shift, high quantum yield, and tunable emission.

Physical exercise is recognized as an effective intervention to improve mood, physical performance, and general well-being. It achieves these benefits through cellular and molecular mechanisms that promote the release of neuroprotective factors. Interestingly, reduced levels of physical exercise have been implicated in several central nervous system diseases, including ocular disorders.

The position that a woman adopts during breastfeeding is important for both infant and maternal health; however, many women experience musculoskeletal pain due to poor posture during breastfeeding, which is a known factor in low exclusive breastfeeding rates. Posture monitoring is an effective intervention, but existing wearable devices do not consider the ergonomics of nursing mothers and breastfeeding scenarios. In this study, nursing underwear was developed with posture monitoring and a real-time feedback system using accelerometers and flexible bending sensors targeting the neck and upper thoracic spine.

An efficient and facile method has been developed for the construction of novel P-S-C and P-Se-C bonds by facilitating the three-component cross-coupling reaction of P-H bonds with elemental sulfur/selenium and vinylsulfonium salts, utilizing sodium bicarbonate as a base. This approach eliminates the need for the use of toxic and odorous active sulfur/selenium reagents and noble metals, thereby offering a new pathway for synthesizing -phosphinothioates and -phosphinoselenoates via the organic conversion of inorganic sources. The reaction has showcased remarkable versatility in terms of substrate applicability, particularly for organophosphorus compounds containing P-H bonds and vinylsulfonium salt derivatives.
