A Termite‐Inspired Alternative to Cement

open access: yesAdvanced Functional Materials, EarlyView.
A termite‐inspired composite of clay, cellulose, and lignin forms a dense fibrous network with concrete‐like strength (32 MPa) and superior elasticity, processed at ambient temperature. Abstract Clay combined with organic materials is used by termites as a strong and durable construction material for their mounds with minimal environmental impact. Here,

A Scalable, Durable, Fire‐Safe All‐Day Passive Radiative Cooling Coating for Sustainable Buildings

open access: yesAdvanced Functional Materials, EarlyView.
This study reports a scalable, durable coating that combines a fire‑retardant copolymer adhesive, hollow glass microspheres, and boron oxide to achieve passive radiative cooling with over 94% solar reflectance and >95% mid‑infrared emissivity. The coating maintains performance after UV and rain exposure and exhibits UL‑94 V‑0 fire resistance, enabling ...

Full‐Spectrum Solar Harvesting and Desalination Enabled by Supra‐Nano Amorphous Ruthenium Dioxide – Mineral Composites

open access: yesAdvanced Functional Materials, EarlyView.
A mineral‐based supra‐nano amorphous ruthenium dioxide composite (a‐Ru0.5‐AM) was designed, achieving 97% broadband solar absorption. Under one sun, it reaches 87.91 ± 0.32 °C with a distinct thermal buffering effect that favors thermal confinement.

Forestry Economics: Principles and Practice [PDF]

open access: yes
This review discusses bioeconomic models of the forest and uses them to explore policy options for forest management. The main type of bioeconomic model used is based on a biomass model of the growth of the forest, similar to the biomass model widely ...

Highly Stable Ion‐Exchange Doping of Organic Semiconductor Single Crystals for Reliable Flexible Sensors

open access: yesAdvanced Functional Materials, EarlyView.
Stable ion‐exchange doping of organic semiconductor single crystals is demonstrated using bulky hydrophobic anions. Electrical conductivity is significantly enhanced and maintained under ambient air and elevated temperatures, while intrinsic strain sensitivity remains intact over 100 000 strain cycles. The approach highlights the critical role of anion

The Plasticizing Mechanism and Effect of Aluminium Chloride and Glycerin on Poly(vinyl alcohol) Films [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 2016
Poly(Vinyl Alcohol) (PVA) films were prepared with AlCl3·6H2O/glycerin and AlCl3·6H2O/poly glycerin as two kinds of complex plasticizer. The micromorphology of pure PVA film and PVA films plasticized with complex plasticizer was observed by Scanning ...
