Soil reinforcement with synthetic and natural fibres: a review [PDF]

open access: yes, 2020
Problematic soil is a common issue in construction activities, particularly when dealing with peat and clay soils of poor geotechnical properties. Such soils are non-homogeneous, and their properties vary greatly from place to place or, in some cases ...

Deployable 3D‐Printed Vascular Stent with Surface‐Catalysed Endogenous Nitric Oxide Generation

open access: yesAdvanced Materials, EarlyView.
A deployable 3D‐printed vascular stent was fabricated with surface‐catalyzed endogenous nitric oxide generation, representing a promising new direction for stent development. The stent can be remotely controlled by magnetic force in its compressed state and fully deployed at the target site using an untethered heat source, potentially eliminating the ...

Design of lightning protection for a full-authority digital engine control [PDF]

open access: yes
The steps and procedures are described which are necessary to achieve a successful lightning-protection design for a state-of-the-art Full-Authority Digital Engine Control (FADEC) system. The engine and control systems used as examples are fictional, but

Self‐Powered Flexible Triboelectric‐Gated Ion‐Gel Transistor for Neuromorphic Tactile Sensing and Human Activity Recognition

open access: yesAdvanced Materials, EarlyView.
A fully flexible ion‐gel‐gated graphene‐channel transistor driven by a triboelectric nanogenerator enables self‐powered tactile sensing and synaptic learning. Mimicking spike‐rate‐dependent plasticity, the device exhibits frequency‐selective potentiation and depression, supporting rate‐coded neuromorphic computation even under flex.

Approaching Carnot efficiency at maximum power in linear response regime

open access: yes, 2019
We construct an example of heat engine whose efficiency at maximum power breaks down the previously derived bounds in the linear response regime. Such example takes a classical harmonic oscillator as the working substance undergoing a finite-time Otto ...

Hydrogel Confinement Strategies for 3D Cell Culture in Microfluidic Systems

open access: yesAdvanced Materials Technologies, EarlyView.
Hydrogel confinement structures are key to organizing 3D cell cultures in microfluidic devices. This review classifies five structural strategies (micropillar, phaseguide, porous membrane, stepped‐height, and support‐free) and examines their trade‐offs alongside fabrication methods.
