The Sol-Gel Route to Nanocomposites
Nanocomposites are multiphase materials where one of the structural units, either organic or inorganic, is in a defined size range 1-100 nm. In order to prepare organic-inorganic nanocomposites either the particles or the polymers or both can be synthesized “in situ” or used in the final state.

Programmable Functional Silicification of DNA Origami Nanostructures
This work introduces additional functionality into silica‐coated DNA origami nanostructures using non‐standard silica precursors. A fluorescent precursor enables enhanced intracellular tracking, while a disulfide‐containing reagent yields redox‐responsive, degradable silica coatings.

Silica Sol-Gel Entrapment of the Enzyme Chloroperoxidase
The enzyme chloroperoxidase (CPO) was immobilized in silica sol-gel beads prepared from tetramethoxysilane. The average pore diameter of the silica host structure (~3 nm) was smaller than the globular CPO diameter (~6 nm) and the enzyme remained ...

Novel sol–gel preparation of (PO)–(CaO)–(NaO)–(TiO) bioresorbable glasses (X = 0.05, 0.1, and 0.15) [PDF]
Quaternary phosphate-based glasses in the PO–CaO–NaO–TiO system with a fixed PO and CaO content of 40 and 25 mol% respectively have been successfully synthesised via sol–gel method and bulk, transparent samples were obtained.

An investigation of the parameters effecting the agglomerate size of a PZT ceramic powder prepared with a sol-gel technique. [PDF]
This paper describes the production of Pb1.0Zr0.9Ti0.1O3 ceramic powder, by using metal organic precursors as starting materials and a polyvinylpyrrolidone (PVP) as an agglomeration control agent.

Sustainable and Multifunctional Natural Macromolecular Polymers for Aqueous Zn Metal Batteries
We comprehensively review the structure‐function relationships and regulatory mechanism of natural macromolecular polymers in stabilizing zinc anodes at the microscopic and mesoscopic scales. The interactions among polymer structures, optimization strategies, and regulatory mechanisms are discussed systematically summarizing recent related research ...

We present SCIENCE, an in‐ear multimodal physiological monitor featuring two key innovations. Water‐triggered morphological expansion (a 2‐mm cylinder to a 9‐mm spindle) achieves conformal adaptation across complex canal geometries. Simultaneously, active biofouling mitigation disrupts cerumen barriers, reducing sensor‐skin impedance by 20%.
