  • MOF-Enhanced Aluminosilicate Ceramic Membranes Using Non-Firing Processes for Pesticide Filtration and Phytochrome Removal.: This research utilizes sodium hydroxide in the development of MOF-enhanced aluminosilicate ceramic membranes. These membranes are crafted through non-firing processes, highlighting their utility in filtering pesticides and removing phytochromes, offering substantial benefits for environmental management and agricultural applications (Zhao L et al., 2024).

  • Assessing the Acidic and Alkaline Recalcitrance of Covalently Modified Surface Amines on Ordered Mesoporous Carbon.: The study examines the resistance of covalently modified surface amines on mesoporous carbon to acidic and alkaline environments, where sodium hydroxide is used to test alkaline recalcitrance. This work is pivotal for applications in catalysis and material science (Kovach NC et al., 2024).

  • Formation of plasmonic core/shell nanorods through ammonia-mediated dissolution of silver(i)oxide for ammonia monitoring.: This article discusses the role of sodium hydroxide in synthesizing plasmonic core/shell nanorods. The process involves ammonia-mediated dissolution, which is critical for developing sensors for ammonia detection in environmental monitoring (Ghorbanian E et al., 2024).

  • High temperature corrosion and oxide scale formation of nickel in molten NaOH at various basicity levels.: Investigates the corrosion behavior and oxide scale formation on nickel in molten sodium hydroxide. This study is crucial for understanding material degradation in high-basicity environments, which has implications for industrial processes involving caustic substances (Stoffersen B et al., 2024).

  • Long-term durability of discarded cork-based composites obtained by geopolymerization.: Focuses on the durability of cork-based composites treated with sodium hydroxide and geopolymerized. This research is significant for waste management and recycling processes, providing insights into sustainable material usage (Poggetto GD et al., 2024).

The extended synaptotagmins (E-Syts) are ER proteins that act as Ca(2+)-regulated tethers between the ER and the plasma membrane (PM) and have a putative role in lipid transport between the two membranes. Ca(2+) regulation of their tethering function, as well

During termination of translation in eukaryotes, a GTP-binding protein, eRF3, functions within a complex with the tRNA-mimicking protein, eRF1, to decode stop codons. It remains unclear how the tRNA-mimicking protein co-operates with the GTPase and with the functional sites on

Rhythmic motor patterns underlying many types of locomotion are thought to be produced by central pattern generators (CPGs). Our knowledge of how CPG networks generate motor patterns in complex nervous systems remains incomplete, despite decades of work in a variety

A key step in the process of metastasis is the epithelial-to-mesenchymal transition (EMT). We hypothesized that epigenetic mechanisms play a key role in EMT and to test this hypothesis we analyzed global and gene-specific changes in DNA methylation during TGF-β-induced

Although label-free biosensors comprised of optical microcavities inherently possess the capability of resolving molecular interactions at individual level, this extreme sensitivity restricts their convenience for large scale applications by inducing vulnerability towards non-specific interactions that readily occur within complex media.
