Tamper‐Responsive Physical Unclonable Functions via Graphene‐Interlayered Block Copolymer Random Structures

open access: yesAdvanced Materials, EarlyView.
Self‐invalidating multilayer physical unclonable functions (PUFs) integrate fingerprint‐like metal nanopattern bilayers from block copolymer templates with highly reactive reduced graphene oxide (rGO) interlayers. This tamper‐responsive architecture blocks all unauthorized physical and chemical replication attempts while autonomously deactivating ...

Generalization of a state-transition model to address degradation of Ecuador's tropical dry forest at a regional scale

open access: yesTrees, Forests and People
Understanding how chronic disturbance leads to forest degradation across an entire ecosystem is necessary to avoid the loss of ecological integrity at scale. In poorly studied ecosystems, expert-based models can help conceptualize the primary drivers and

Ti3C2Tx MXene/Silver Composite Foams For Lightweight, High‐Performance Electromagnetic Interference Shielding and Joule Heating

open access: yesAdvanced Materials Interfaces, EarlyView.
Ultrathin MXene/EMF composite foams achieve a specific shielding efficiency of 749.6 dB.dB·cm3$\mathrm{dB}\cdot {\mathrm{cm}}^{3}$/g, while the silver‐enhanced MXene/Ag/EMF reaches 81.4 dB shielding effectiveness at just 1.0 mm thickness. Both composites exhibit rapid Joule heating, retain stability up to 250∘C$^\circ{\rm C}$, and withstand 1000 ...

The Safety-net Use of Non Timber Forest Products [PDF]

open access: yes
Incompleteness of insurance markets is a crucial weakness of developing countries. In this context, the poor households of rural regions often exploit common property resources, such as forests, as insurance in case of economics stress.

Advanced MXene‐Based Multifunctional Nanoarchitecture Materials Engineered for Adsorptive Cleanup of Hazardous Radioactive Pollutants: A Comprehensive Critical Review

open access: yesAdvanced Materials Interfaces, EarlyView.
This work critically reviews MXenes as highly effective multifunctional nanomaterials for the adsorption of radio‐contaminants, demonstrating a remarkable adsorption capacity of up to 1376.75 mg/g and cyclic stability of 2–8 cycles, with complexation, electrostatic interactions, and the numerical strength of MXene active sites playing a key operational

Land use dynamics, tree diversity and local perception of dry forest decline in southern Burkina Faso, West Africa [PDF]

open access: yes, 2008
Conversion of tropical forests into cropland and pasture has risen incessantly during the last few decades. With the aim of providing evidence for informed-decision on sustainable forest management, this thesis examined the dynamics of land use change in

Adsorbent Materials for Hydrocarbons Removal by Geopolymerization of Halloysite Clay Nanotubes Filled Within Chitosan Matrix

open access: yesAdvanced Materials Interfaces, EarlyView.
Alkaline activation of halloysite clay nanotubes embedded in a chitosan matrix converts bionanocomposite films into porous geopolymeric materials with enhanced adsorption capacity toward hydrocarbons in both vapor and aqueous phases. The improved adsorption performance was demonstrated by the efficient capture of dodecane vapors and phenol from water ...
