Nature‐Inspired Functional Aerogel Fibers with Engineerable Core–Shell Morphology

Advanced Materials Technologies, EarlyView.
Nature‐inspired core–shell aerogel fibers are fabricated through coaxial wet‐spinning, which combines a polyimide shell with MXene core. The fibers exhibited absorption‐dominant EMI shielding, low thermal conductivity, and mechanical robustness, demonstrating multifunctional potential for wearable electronics and advanced smart textiles.

Hundreds of Nanocoulomb Electron Acceleration Driven by Multipetawatt Laser in Subcritical Density Plasmas

Advanced Photonics Research, EarlyView.
Electron acceleration using multipetawatt femtosecond lasers and subcritical density plasmas achieves a maximum charge of 245 nC, with an injection rate of up to 100 nC per picosecond. The charge variation with plasma density, initially increasing and then decreasing, arises from the competition between the injection of multiple plasma waves and laser ...

Effect of biofuel E85 combustion on fuel consumption in spark-ignition engines

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2012
Biofuels represent an alternative source of energy that should gradually decrease our dependence on crude oil. A rapid development of their use in combustion engines is above all the consequence of their very positive balance of emissions.

A Skin‐Adherent Magneto‐Inertial Wearable for Real‐Time Joint Motion Analysis

Advanced Sensor Research, EarlyView.
An imperceptible magneto‐inertial wearable couples a skin‐adherent PDMS‐NdFeB patch with a 9‐DoF IMU to track joint kinematics in real time and classify range‐of‐motion (Limited/Normal/Hypermobile) via a 1D‐CNN (95.3% accuracy). Wireless BLE streaming and a mobile app enable feedback.

Transformation of a Silicate Material for Carbon Negative Magnesia‐Based Cement via Electrochemistry

Advanced Science, EarlyView.
The transformation of a magnesium trisilicate material via water electrolysis into precursor phases necessary for magnesium‐based M‐S‐H cement is explored. The dissolution of the material mediated electrochemically is monitored, and the analysis of the resulting phases indicate their suitability as effective precursors for M‐S‐H cement.

Storage Potential of Soil Functional Carbon Fractions in the World's Largest Plantations

Advanced Science, EarlyView.
Climate warming and drying increase the loss of mineral‐associated and particulate organic carbon during the conversion of natural forests to plantations. Based on a survey of the world's largest plantations, the study quantifies the soil carbon deficit in plantations and assesses benchmarks and targets for functional soil organic carbon, highlighting ...
