Using the strong reduction potential of the liquid NaK-78 alloy, we present a new versatile template-free approach to the synthesis of porous metal- and metalloid-based nanomaterials. With this novel approach, NaK can be simultaneously used as an agent for reduction, structure directing, and pore formation without the use of additional reagents.

Phase change materials that can absorb or release large amounts of heat during phase transition, play a critical role in many important processes, including heat dissipation, thermal energy storage, and solar energy utilization. In general, phase change materials are usually encapsulated in passive modules to provide assurance for energy management. The shape and mechanical changes of these materials are greatly ignored.

By overcoming all conventional limitations associated with the synthesis of metalloid micro- and nanoparticles in aqueous media, we present a new one-step approach to the synthesis of highly crystalline metalloid hollow architectures. The liquid metal-mediated synthesis of Ge- and Sb-based hollow structures with satisfactory reaction kinetics at room temperature and normal pressure is presented.

Magnetic nanoparticles are a prospective class of materials for use in biomedicine as agents for magnetic resonance imagining (MRI) and hyperthermia treatment. However, synthesis of nanoparticles with high efficacy is resource-intensive experimental work. In turn, the use of machine learning (ML) methods is becoming useful in materials design and serves as a great approach to designing nanomagnets for biomedicine.

Active controlling of optical properties of metallic particles holds great promise for nonlinear nanophotonics and compact optoelectronic devices. Except for the electronic and chemical tuning of their properties, active control through fast and reversible shape modulation remains a significant challenge. Here, we report on the concept for changing the color and brightness of single particles by reversible/irreversible tuning of their shapes.
