AI Article Synopsis

  • Deformable spherical aggregates of metal nanoparticles connect through long-chain dithiol ligands to form macroscopic nanostructured materials that can be shaped and molded.
  • These materials can be thermally hardened into metal structures with adjustable porosity and maintain electrical conductivity in both their plastic and hardened forms.
  • The self-assembly technique is versatile, suitable for creating materials from pure metals as well as bimetallic compositions.

Article Abstract

Deformable, spherical aggregates of metal nanoparticles connected by long-chain dithiol ligands self-assemble into nanostructured materials of macroscopic dimensions. These materials are plastic and moldable against arbitrarily shaped masters and can be thermally hardened into polycrystalline metal structures of controllable porosity. In addition, in both plastic and hardened states, the assemblies are electrically conductive and exhibit Ohmic characteristics down to approximately 20 volts per meter. The self-assembly method leading to such materials is applicable both to pure metals and to bimetallic structures of various elemental compositions.

Mandibular Prognathism Correction in a Juvenile Umbrella Cockatoo () With the Use of an Orthosis.

J Avian Med Surg

January 2025

Stahl Exotic Animal Veterinary Services, Fairfax, VA 22030, USA.

A 9-week-old male umbrella cockatoo () presented with mandibular prognathism. The rostral rhinothecal tomial length appeared subjectively shorter than the rostral gnathothecal length, which was subjectively rostrally elongated. After an initial orthosis failed, a second orthosis was designed that employed the use of an orthopedic wire anchor in the rostral end of the rhinotheca, leaving the premaxillary bone undisturbed.

A Moldable, Tough Mineral-Dominated Nanocomposite as a Recyclable Structural Material.

Small

January 2025

School of Chemical Engineering and Technology, State Key Laboratory of Chemical Engineering, Tianjin University, Tianjin, 300072, P. R. China.

Flexible hybrid minerals, primarily composed of inorganic ionic crystal nanolines and a small amount of organic molecules, have significant potential for the development of sustainable structural materials. However, the weak interactions and insufficient crosslinking among the inorganic nanolines limit the mechanical enhancement and application of these hybrid minerals in high-strength structural materials. Inspired by tough biominerals and modern reinforced concrete structures, this study proposes introducing an aramid nanofiber (ANF) network as a flexible framework during the polymerization of calcium phosphate oligomers (CPO), crosslinked by polyvinyl alcohol (PVA) and sodium alginate (SA).

Injection-molded thermoplastic cassava starch modified with single and mixed polyol plasticizers.

Int J Biol Macromol

November 2024

Department of Packaging and Materials Technology, Faculty of Agro-Industry, Kasetsart University, Bangkok 10900, Thailand; Center for Advanced Studies for Agriculture and Food (CASAF), Kasetsart University Institute for Advanced Studies (KUIAS), Kasetsart University, Bangkok 10900, Thailand. Electronic address:

Increasing interest in biodegradable and cost-effective materials derived from renewable resources has led to the development of injection-moldable thermoplastic starch (TPS). Plasticizers constitute an indispensable additive for manufacturing TPS, influencing both its thermomechanical processability and performance. The aim of the current work is thus to study the effect of single and mixed polyol plasticizers on the performance of injection-molded TPS.

Self-healing, stretchable, and moldable hydrogels have a great potential application in tissue engineering and soft robotics. Despite great success in reported hydrogels, it is still a great challenge to construct the moldable hydrogels with an ultrafast self-healing performance. Herein, the composite hydrogels (PBLH) with ultrafast self-healing, stretchable, and moldable properties were successfully constructed by poly (vinyl alcohol) (PVA), borate (B), ε-poly-l-lysine (EPL), and hyaluronic acid (HA) based on an efficient one-pot method.
