Investigation on tunnel stability considering pipe‐roof support with transparent soil technology

Deep Underground Science and Engineering, EarlyView.
This study integrates transparent soil technology, 3D reconstruction and numerical simulation to captures the full‐field deformation of shield tunnel instability. Results demonstrate that pipe‐roof support enhances stability via the “soil‐arching barrier effect,” effectively restraining failure wedge development by extending stress transfer paths ...

Multi-criteria ranking of indoor air quality in non industrial environments [PDF]

, 2005
\ud Relative to other western nations, there is a paucity of information on indoor air organic pollutants in Australia. While some data are available on the indoor levels of volatile organic compounds in Australian dwellings, corresponding information on

Polyelectrolyte Layer as a Work Function Modifier for Transparent Electrodes Enabling Efficient Perovskite Solar Cells With Superior Low‐Light Performance

EcoEnergy, EarlyView.
Polyelectrolytes represent a low‐cost and effective platform for tailoring charge extraction interfaces in inverted perovskite solar cells (PSCs). In this work, we introduce a protonated polyethyleneimine (PEI) layer (pH = 2) between the ITO electrode and the PTAA hole transport layer to increase the apparent work function of ITO by 0.066 eV and reduce

Fluorescent Colored Passive Radiative Cooling Based on Carbon Dots for Cooling Power Recovery

EcoEnergy, EarlyView.
We demonstrate colored passive radiative coolers consisting of a highly reflective porous ceramic base covered by an eco‐friendly luminescent carbon dot‐polymer composite, with two types of carbon dots enabling conversion of either ultraviolet or visible light, respectively.

Origin of Physicochemical and Mechanical Stability of Low‐Temperature Prepared TiO2‐Based Photocatalytic Films: Surface Hydroxyl Density Matching

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Material science advances show how surface chemistry improves low‐temperature prepared TiO2‐SiO2 composite films. Using a colloidal‐based synthesis method instead of a powdered‐based one, researchers exploit hydroxyl groups' interfacial interactions to create nanoscale structures with superior physicochemical and mechanical stability.

A Body‐Coupled Electronic Skin With Branch‐Enhanced Grid Architecture for Fine Tactile Sensing

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Ambient power‐frequency electric fields, commonly regarded as harmful environmental exposure, are converted into a usable energy source for self‐powered tactile sensing. A branch‐enhanced grid electronic skin based on body‐coupled electric‐field sensing is developed, where branched conductive networks enlarge the effective sensing area and enable ...
