This study introduces a back filter installed at the end of the exhaust pipe of city buses. The impact of the metal type used in its construction on the absorption of suspended particles and the reduction of sulfides in diesel engine exhaust gases is investigated. The back filter is constructed from three metals: copper, zinc, and nickel.

A CoO/AgMoO/CeOternary nanocomposites photocatalyst was successfully synthesized through a straightforward ethanol-assisted chemical method. Comprehensive characterization of its structural and optical properties was conducted using X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), Raman spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM), UV-Vis diffuse reflectance spectroscopy (UV-DRS), and photoluminescence (PL) analysis. XRD analysis confirmed the presence of CoO, AgMoO and CeO in the ternary composite sample.

The electrolyte-electrode interface serves as the foundation for a myriad of chemical and physical processes. In battery chemistry, the formation of a well-known solid-electrolyte interphase (SEI) plays a pivotal role in ensuring the reversible operations of rechargeable lithium-ion batteries (LIBs). However, characterizing the precise chemical composition of the low crystallinity and highly sensitive SEI presents a formidable challenge.

The development of analytical techniques applicable to powdered pharmaceutical co-crystals, including those containing excipients, represents a comprehensive strategy for quality control in both drug development and regulatory settings. This study investigates the structural characterization of indomethacin-nicotinamide co-crystals using a combination of microcrystal electron diffraction (microED), solid-state NMR (SSNMR), Raman spectroscopy, and powder X-ray diffraction (PXRD). MicroED analysis revealed the crystal structure of the co-crystal, while SSNMR measurements provided insights into the molecular interactions within the structure.

The abnormal expansion of GGGGCC (G4C2) repeats in the noncoding region of the C9orf72 gene is a major genetic cause of two devastating neurodegenerative disorders, amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). These G4C2 repeats are known to form G-quadruplex (G4) structures, which are hypothesized to contribute to disease pathogenesis. Here, we demonstrated that four DNA G4C2 repeats can fold into two structurally distinct G4 conformations: a parallel and an antiparallel topology.
