Real‐Time Self‐Optimization of Quantum Dot Laser Emissions During Machine Learning‐Assisted Epitaxy

Advanced Science, EarlyView.
This work presents a machine learning‐driven approach integrated with in situ high‐energy electron diffraction (RHEED) monitoring to automate the optimization of quantum dot (QD) growth for lasers. A 3.2‐fold increase in photoluminescence intensity is achieved alongside a narrow spectral linewidth.

Influence of secondary gas on control characteristics of ICP-RF plasma torches [PDF]

arXiv, 2013
Thermal plasma characteristics inside an atmospheric pressure Radio-Frequency Argon plasma torch have been studied by numerically solving axis-symmetric 2-D Magnetohydrodynamics equations, energy transport equations and species conservation equation coupled with 2D Maxwell equations in the vector potential form.

Ecofriendly Upcycling of Poly(vinyl chloride) Waste Plastics into Precious Metal Adsorbents

Advanced Science, EarlyView.
Poly(vinyl chloride) waste plastics are simply transformed into high‐performance precious metal (PM) adsorbents via a facile and green hydrazine‐functionalization process. The resultant adsorbent effectively and selectively recovers PM from real‐world leachates via its combined chemisorption and reduction mechanisms.

The ‘caged torch procession’: Celebrities, protesters and the 2008 Olympic torch relay in London, Paris and San Francisco [PDF]

, 2010
Along with the opening and closing ceremonies, one of the major non-sports events associated with the modern Olympic Games is the torch relay. Although initiated in 1936, the relay has been subject to relatively little academic scrutiny.

Twin Toughening‐Driven Martensitic Transformation Strategy Synergistic Improvement for Plasticity‐Thermal Shock Resistance of (Hf─Zr─Ti)C Ceramic Coating in Severe Thermal Environments

Advanced Science, EarlyView.
A “ceramic self‐toughening strategy” is introduced for enhancing the plasticity and thermal shock resistance of (Hf─Zr─Ti)C coatings through twin toughening‐driven martensitic transformations in oxide scales. It facilitated the formation of stable, dense, and high‐toughness oxide scales after repeat ablation, and endowed prepared coatings with superior

Bandgap‐Dependent Doping of Semiconducting Carbon Nanotube Networks by Proton‐Coupled Electron Transfer for Stable Thermoelectrics

Advanced Electronic Materials, EarlyView.
Proton‐coupled electron transfer doping with benzoquinone is applied to p‐dope dense films of semiconducting single‐walled carbon nanotubes. The doping efficiency depends on the pH of the doping solution and the bandgap of the nanotubes. The highest conductivities and power factors are achieved for small‐bandgap nanotubes, remaining stable for over 120

Literary reading and eating disorders: survey evidence of therapeutic help and harm

Journal of Eating Disorders, 2018
Background There is growing evidence for the efficacy of self-help bibliotherapy as a treatment for eating disorders, although little understanding of how specific linguistic characteristics may enhance or constrain its effects.
