In the crystal of the title compound, 2C(5)H(7)N(2) (+)·C(4)N(4)S(6) (2-)·H(2)O, inter-molecular N-H⋯S and N-H⋯N hydrogen bonds link four cations and two dianions into a centrosymmetric cluster. The crystal packing is further consolidated by π-π inter-actions between the five- and six-membered rings of neighbouring clusters [centroid-centroid distances = 3.692 (3), 3.718 (3), 3.660 (3) and 3.696 (3) Å] and via O-H⋯N, O-H⋯S and N-H⋯O hydrogen bonds involving the uncoordinated water mol-ecules.

In this paper, cellulose-lignin films containing Fe were prepared by the codissolution-precipitation method, and the films have high transparency as well as high UV absorption. In this process, kraft lignin chelates with Fe and then bonds with cellulose through hydrogen bonding, evenly distributing within the film. The morphological results showed that the kraft lignin chelated with Fe bound tightly linked to cellulose within the Fe@cellulose-lignin composite films.

This study addresses the need for sustainable fruit preservation packaging by developing biodegradable films from nonconventional starch sources. The purpose was to enhance film properties and antioxidant capabilities using fatty acid-modified Artocarpus lakoocha starch films incorporated with thymol. The objective is to evaluate the impact of fatty acid modification on film characteristics and the antioxidant potential of thymol-unfused films.

Steroids are organic compounds found in all forms of biological life. Besides their structural roles in cell membranes, steroids act as signalling molecules in various physiological processes and are used to treat inflammatory conditions. It has been hypothesised that in addition to their well-characterised genomic and non-genomic pathways, steroids exert their biological or pharmacological activities an indirect, nonreceptor-mediated membrane mechanism caused by steroid-induced changes to the physicochemical properties of cell membranes.

This study investigates the structural and dynamic properties of ternary mixtures composed of NaPF, ethylene carbonate (EC), and the ionic liquid choline glycine (ChGly), with a focus on their potential as electrolytes for supercapacitors. The combination of NaPF-EC, known for its high ionic conductivity, with the biodegradable and environmentally friendly ChGly offers a promising approach to enhancing electrolyte performance. Through molecular simulations, we analyze how the inclusion of small concentrations of ChGly affects key properties such as density, cohesive energy, and ion mobility.

In the face of advancements in microrobotics, intelligent control and precision medicine, artificial muscle actuation systems must meet demands for precise control, high stability, environmental adaptability and high integration miniaturization. Carbon materials, being lightweight, strong and highly conductive and flexible, show great potential for artificial muscles. Inspired by the butterfly's proboscis, we have developed a carbon-based artificial muscle, hydrogen-substituted graphdiyne muscle (HsGDY-M), fabricated efficiently using an emerging hydrogen-substituted graphdiyne (HsGDY) film with an asymmetrical surface structure.
