Summary: This study investigated an efficient and inexpensive method for the removal of EtBr using chromatin extracted from common carp testis. The results showed that chromatin had a high removal efficiency and adsorption capacity for EtBr. The adsorption process followed pseudo-second-order kinetics and Langmuir isotherm model. Thermodynamic analysis revealed that the adsorption of EtBr by chromatin was a spontaneous process dominated by hydrogen bonding and van der Waals forces. This work offers a potential solution for the decontamination of EtBr and removal of analogs.

Summary: Development of an important and easy analytical method for screening silver ore samples is crucial for resource exploration and mining. A selective Ag+-promoted photosensitization colorimetric assay was developed, which allowed highly sensitive colorimetric detection of Ag+ with a visual limit of quantification as low as 0.2 ng/mL. The accuracy of the method was verified through analyzing certified reference material and real ore samples, showing good agreement with the results obtained by electrothermal atomic absorption spectrometry (ET-AAS).

Summary: A facile method for preparing a gold nanostar-graphene quantum dot composite was reported, which resulted in highly active surfactant-free gold nanostars. The composite was used in a new sensing strategy for colorimetric detection of cysteine by studying its etching reaction with Na2SO3. Larger gold nanostars showed greater activity in the etching reaction, and pre-added cysteine protected the nanostars from etching, allowing for sensitive detection of cysteine with a detection limit of 0.35 nM.

Summary: This study focused on the use of pine rosin as a natural antibacterial chemical and analyzed the weathering of melt-spun polyethylene (PE) and poly lactic acid (PLA) polyfilaments. The results showed that adding a copolymer surfactant can help achieve a high content of rosin in the fibers while reducing total emissions. PE fibers were found to be more durable throughout the aging study, and fibers containing rosin showed similar antibacterial effects to commercial silver-containing antimicrobial.

Summary: Transparent, flexible, and chemically stable conducting electrodes are crucial for optoelectronic device fabrication. This study explores metal-semiconductor (MS) junctions utilizing two-dimensional (2D) MXene nanosheets and Al-doped ZnO nanoparticles. The heterojunctions were formed by layer-by-layer self-assembly on an indium tin oxide (ITO) substrate and characterized using scanning tunneling microscopy (STM) and spectroscopy. The results demonstrate the ability to manipulate the MS junction properties, such as rectification ratio and contact resistance, by functionalizing the 2D-metal MXene and doping the ZnO nanoparticles.
