Intelligent Continuum Micromachines in Complex Confined Spaces

SmartBot, EarlyView.
The cover depicts a conceptual design for an intelligent continuum micromachine entering a target capsule used in fusion‐energy research through its slender gas‐fill tube. By combining route‐adaptive deformation, embedded sensing, and a functional end effector, the robot could inspect hidden defects, assess local conditions, and support localized ...

Influence of Temperature on the Reliability of Graphene‐Based Ozone Sensors

Small, EarlyView.
The reliability and stability of inkjet‐printed graphene flake sensors are evaluated. Stress assessments take place in ozone‐rich environments and at elevated temperatures, with the observation of a change in resistance. Surface‐sensitive techniques serve to investigate the failure and degradation mechanisms of printed graphene.

Solar‐Powered Water Depollution Through a Bioinspired Device Based on ZIF‐8 Loaded Macroporous Hydrogels Prepared via Ice‐Templating

Small, EarlyView.
ABSTRACT Water pollution poses a constant threat to the environment and is one of the central causes for global shortage of clean water. Metal–Organic Frameworks (MOFs) have emerged as highly efficient adsorbents; however, their application is limited by their common production as fine powders, which hinders recovery and reuse.

Colloidal Behavior of Carbonate Particles Microbially Precipitated in Microfluidic Droplets

Small, EarlyView.
In Microbially Induced Calcium Carbonate Precipitation (MICP), ureolytic bacteria trigger calcium carbonate precipitation via pH‐increasing urea hydrolysis. This enzymatically driven reaction induces the colloidal assembly of bacteria and carbonate particles into fractal networks.

Adsorption‐Programmed Transformation of a Two‐Dimensional Cu–Imidazolate Framework into Mn‐Integrated Catalytic Nanonetwork

Small, EarlyView.
A freeze‐dried copper‐based metal‐organic framework removes more than 95% of manganese from water. Capturing the metal reorganizes the framework, giving the used adsorbent a second life as a reusable catalyst that produces valuable ester products in yields up to 84%.

The Immobilization Mechanism of Inorganic Amendments on Cu and Cd in Polluted Paddy Soil in Short/Long Term

Toxics
This study investigated the impact of soil colloidal characteristics on the transfer patterns of different Cu and Cd speciation in contaminated soil treated with three different amendments: lime (L), zero-valent iron (ZVI), and attapulgite (ATP).

Advances in research on layered double hydroxides for biomedical applications

Smart Molecules, EarlyView.
Layered double hydroxides (LDHs) are pH‐responsive nanomaterials with broad biomedical applications. This review summarizes LDH synthesis methods and compares their advantages. It highlights LDHs' progress in cancer therapy, including chemo‐photothermal, chemo‐immunotherapy, and photodynamic‐immunotherapy combinations and their potential in bone repair.

Wildfire Ash Alters Freshwater Crustacean Behavior: Disentangling the Contributions of Suspended Macroparticles and Ash‐Induced Alkalinization

Environmental Toxicology, EarlyView.
ABSTRACT Climate change and anthropogenic ignitions are intensifying wildfire frequency worldwide, elevating the risk of freshwater contamination by ash. In water, dissolved ash releases ions and other toxic constituents that increase pH and alter physicochemical conditions, while suspended ash particles may impose mechanical stress, disrupt behavior ...
