Advanced Science, EarlyView.Stable radicals are attractive for photonic and quantum information technologies but are often limited by instability. We stabilize intrinsic radicals in graphene quantum dots via 2D polymerization of perylene derivatives, where bilayer defect confinement suppresses quenching (100–500 K).

RESEARCH ON THE CALCULATION MODEL OF DENT WITHOUT CONCAVE ANGLE ON OIL AND GAS PIPELINE
Jixie qiangdu, 2017 The most common type of pipe mechanical damage is dent defect,which is a major cause of leading to pipeline fatigue rupture. For further research on the security of the pipelines,it is necessary to establish a calculation model serving actual conditions.

Improvement of volume estimation of stockpile of earthworks using a concave hull- footprint [PDF]
Micro, Macro & Mezzo Geoinformation, 2015 In the estimation of volume of stockpiles of earthworks, the question is no longer whether the data collected is dense and accurate (equipment and techniques capable of accurate data measurement are available), but how to manipulate the data to yield ...

Environmental Effects on RRAM Cells Based on 2D Halide Perovskite Materials
Advanced Electronic Materials, EarlyView.RRAM offers high speed, scalability, and low power, positioning it as a next‐generation non‐volatile memory. Two‐dimensional halide perovskites show promise due to tunable optoelectronic properties and flexible processing but suffer from environmental sensitivity. This review examines degradation from humidity, temperature, light, and strain, discusses

Advanced Energy Materials, EarlyView.A combination of discrete and finite element method models for the current collector deformation and electrochemical performance analysis, respectively. The models are calibrated and validated with electrochemical and imaging data of hard carbon electrodes. These electrodes were manufactured with different parameters (slurry solid contents of 35 and 40
