MTM1's structure includes three domains: an N-terminal GRAM domain interacting with lipids, a phosphatase domain, and a coiled-coil domain that mediates dimerization of Myotubularin homologues. While phosphatase domain mutations of MTM1 are frequently reported, mutations in the protein's two remaining domains also occur with notable frequency in XLMTM. To ascertain the multifaceted structural and functional consequences of missense mutations in MTM1, we compiled a set of missense mutations and performed in silico and in vitro studies. A conspicuous deficiency in substrate binding, along with the elimination of phosphatase function, was observed in a small number of mutants. Mutations in non-catalytic domains were also observed to potentially have significant long-term effects on phosphatase activity. Coiled-coil domain mutants are now characterized in the XLMTM literature for the first time, as reported in this study.

Lignin, the most abundant form of polyaromatic biopolymer, is ubiquitous. A multitude of applications has arisen from the rich and varied chemical nature of the material, including the design and creation of functional coatings and films. Lignin biopolymer, in addition to replacing fossil-based polymers, can be a component of innovative material solutions. Additional functionalities, including UV shielding, oxygen absorption, antimicrobial protection, and protective barriers, can be integrated, drawing upon the unique inherent properties of lignin. Following this, a variety of applications have been introduced, encompassing polymer coatings, adsorbents, paper sizing additives, wood veneers, food packaging, biomaterials, fertilizers, corrosion inhibitors, and antifouling membranes. Technical lignin is currently produced in considerable quantities by the pulp and paper industry, yet biorefineries of the future are projected to provide a much wider selection of products. Developing new applications for lignin is, therefore, a top priority, from both a technological and an economic perspective. This review article comprehensively summarizes and analyzes the current research on functional lignin-based surfaces, films, and coatings, emphasizing the development and deployment of these solutions.

This paper reports the successful synthesis of KIT-6@SMTU@Ni, a novel heterogeneous catalyst that is both environmentally friendly and green, via a novel method for stabilizing Ni(II) complexes onto modified mesoporous KIT-6. The catalyst (KIT-6@SMTU@Ni) was characterized by using Fourier transform infrared spectroscopy (FT-IR), Brunauer-Emmett-Teller (BET) calculation, X-ray diffraction (XRD), atomic absorption spectroscopy (AAS), energy-dispersive X-ray spectroscopy (EDS), X-ray mapping, thermogravimetric analysis (TGA) techniques, and scanning electron microscopy (SEM). After a comprehensive characterization, the catalyst was successfully applied to the synthesis of 5-substituted 1H-tetrazoles and pyranopyrazoles. Sodium azide (NaN3) and benzonitrile derivatives were the starting materials for the synthesis of tetrazoles. The KIT-6@SMTU@Ni catalyst demonstrated exceptional efficiency and practicality in synthesizing all tetrazole products with high yields (88-98%), high turnover numbers (TON), and turnover frequencies (TOF) achieved within a reasonable time period of 1.3 to 8 hours. The reaction of benzaldehyde derivatives with malononitrile, hydrazine hydrate, and ethyl acetoacetate facilitated the preparation of pyranopyrazoles with high turnover numbers, high turnover frequencies, and excellent yields (87-98%) during the specified reaction time (2 to 105 hours). Five consecutive executions of KIT-6@SMTU@Ni are possible without the need for reactivation. This plotted protocol showcases substantial benefits including the implementation of green solvents, the use of readily available and affordable materials, exceptional catalyst separation and reusability, a rapid reaction time, a considerable product yield, and a facile workup procedure.

The surface of a carbon nanocone (CNC) reacting with cyanogen chloride (ClCN) was the subject of a Density Functional Theory (DFT) investigation. The outcomes of this study highlight that pristine CNC's minimal alterations in electronic properties make it unsuitable for the detection of ClCN gas. Various methods were employed to improve the characteristics of carbon nanocones. A combination of pyridinol (Pyr) and pyridinol oxide (PyrO) functionalized the nanocones, alongside metal decorations of boron (B), aluminum (Al), and gallium (Ga). Moreover, the nanocones were supplemented with the same third-group elements (boron, aluminum, and gallium) as dopants. Simulation data showed that the use of aluminum and gallium atoms as dopants generated promising outcomes. Employing a comprehensive optimization process, two stable configurations emerged for the ClCN gas interacting with the CNC-Al and CNC-Ga frameworks (S21 and S22), featuring Eads values of -2911 kcal mol⁻¹ and -2370 kcal mol⁻¹ respectively, computed at the M06-2X/6-311G(d) level.
