Summary: Molybdenum disulfide (MoS2) sheets were obtained by exfoliating bulk powders in a solution containing tryptophan, and then drop-casted onto a glassy carbon electrode (GCE) to form GCE/MoS2. Electrodeposition of amorphous MoSx onto the GCE was used for comparison. Both electrodes were employed for the electrochemical detection of metronidazole (MTZ), but GCE/MoS2 showed superior performance due to its larger surface area, lower charge-transfer resistance, and the presence of edges and defects that facilitated the electron transfer reaction. Impressive linear calibration curves were obtained for GCE/MoS2, with a wide concentration range and high sensitivity.

Summary: In this study, a white light emitting hydrogel with multi-stimuli responsive properties was prepared by doping Eu3+ and Tb3+ into a blue emission low molecular weight gelator. The hydrogel showed excellent responsiveness to pH, temperature, and chemicals, and could be used for temperature sensing and Cu2+ detection. It could also be used to construct soft materials of a full-color system and anti-counterfeiting materials. This study provides a new approach for preparing smart white light emitting hydrogels with multiple functions.

Summary: The study investigated the photocatalytic performance of CuS/S-C3N4 photocatalyst under visible and near-infrared light irradiation, showing that 2%wt of CuS/S-C3N4 had the highest efficiency in degrading tetracycline (TC) and maintained high photocatalytic stability. Excessive CuS loading led to inactive sites on S-C3N4, decreasing its light absorption ability.

Summary: The potential of Bi2MoO6 nanoparticles as a photocatalyst for decomposing organic pollutants has been widely explored, but their potential for photodynamic therapy (PDT) has not been investigated. In this study, a novel nanocomposite based on Bi2MoO6/ MoS2/AuNRs was designed to overcome the limitation of UV absorption. The nanocomposite exhibited high photodynamic ability and POD-like activity under NIR-II light irradiation.

Summary: A multimodal synergistic antibacterial hydrogel based on dopamine-modified oxidized hyaluronic acid was developed, showing good antibacterial activity against E. coli and S. aureus with an antibacterial rate of 99.99%. The hydrogel was constructed by mixing dopamine-modified oxidized hyaluronic acid with cationic antimicrobial peptide polylysine via Schiff base and coordination complexation, and loading glucose oxidase-loaded MoS2 nanosheets into the hydrogel. This research demonstrates the potential of the developed hydrogel in antibacterial applications.

Summary: This study investigates the inverse-gelation process of methylcellulose in an aqueous medium using dynamic light scattering. The results show that methylcellulose can form an entangled network at specific temperatures. Computational studies also reveal that the entanglement of cellulose molecules is affected by molecular orientation and hydrogen bonding.

Summary: In this study, we introduce carbon monoxide-photoreleasable compounds (photoCORMs) comprised of heptamethine cyanine and flavonol chromophores, which are activated by near-infrared light. These compounds exhibit excellent CO-release yields and uncaging cross sections in aqueous solutions, and their water solubility is enhanced through polar substituents or a host-guest approach using cucurbit[7]uril. Additionally, these hybrids demonstrate outstanding biocompatibility as well as diverse, structure-dependent cell penetrability and internalization.

Summary: The visible-light-induced photoredox carbon radical formation from aqueous sulfoxonium ylides has been demonstrated for the first time. Direct reduction of sulfoxonium ylides by H2O generates hydrocarbon compounds efficiently, while the use of additional alkenes as radical acceptors changes the chemical reactivity to achieve alkene carboarylation of N-arylacrylamides. Mechanistic studies reveal two different reaction pathways involved in the carbon radical formation from aqueous sulfoxonium ylides resulting in reduction to release dimethyl sulfone and carboarylation to form DMSO.

Summary: MoS2 nanoflowers were used as a substrate for the deposition of AuAg or Au nanoparticles, resulting in photothermal-assisted catalysts with different nanostructures. The catalytic reduction of 4-nitrophenol to 4-aminophenol was evaluated. The hydrothermal synthesis of MoS2 nanoflowers provided a material with broad absorption in the Vis-NIR region. Alloyed AuAg and Au nanoparticles were grafted onto MoS2 nanoflowers, leading to nanohybrids with photothermal properties. The AuAg-MoS2 nanohybrid showed better catalytic activity than the Au-MoS2 nanohybrid.

Summary: Through a systematic study on the gelation behavior of carbon-based 0D quantum dots, 1D carbon nanotubes (CNTs), and 3D fullerenes, acidified 1D CNTs are found to be an alternative building block for constructing purely inorganic biomimetic soft materials. The resulting CNT gels exhibit pH- or photothermal-triggered mechanical and tribological adaptivity, simulating the behaviors of sea cucumbers, peacock mantis shrimps, mammalian muscles or cortical bones, and possessing a unique damping property similar to spider's cuticular pad. These CNT gels can also function as smart lubricants, with controllable friction and wear regulated by internal pH changes or near-infrared (NIR) light irradiations.

Summary: In this article, a novel catalytic reaction using Pd(0) and Bronsted acid is reported for the synthesis of biologically important imidazolidinone-fused N-heterocycles through redox-neutral intramolecular N-allylation of indoles and pyrroles with alkynes. This atom-economical method is applicable to a wide range of substrates and eliminates the need for leaving groups or oxidizing agents commonly used in traditional allylation reactions.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.

Summary: In this study, the synthesis of functionalized benzo[a]phenazines and indazolo[2,3-a]quinolines was achieved through Rh(III)-catalyzed oxidative annulation of 2-arylquinoxalines and 2-aryl-2H-indazoles with allyl alcohols. The method showed a wide substrate scope, excellent functional group tolerance, good to high yields of annulated products, and the capability for scaled-up synthesis. A tentative mechanism of the annulation reaction was proposed based on a preliminary mechanistic investigation.
