Bio‐Inspired Ordered WO3 Nano‐Helixes Enable Multi‐Band Electrochromic Smart Windows with Ultrafast Switching and Robust Cyclability

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Biomimetic ordered nano‐helix WO3 films enable multi‐band electrochromic photothermal management across the visible, near‐infrared, mid‐ and long‐wave infrared spectra, with ultrafast switching (<3 s) and robust durability (>10 000 cycles). These findings establish new paradigms for next‐generation photothermal management systems and energy‐efficient ...

A Review of Black Phosphorus‐Based Materials: From Preparation Strategies to Characterization Techniques

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The structure, properties, preparation methods, and characterization techniques of BP. As a typical 2D layered material, black phosphorus (BP) demonstrates exceptional promise in various fields, particularly in energy storage for alkali metal‐ion batteries. However, its distinctive structure and properties, together with the compositional complexity of

Activating and Stabilizing Lattice Oxygen in Spinel NiCo2O4 through F, Mn Dual Doping for Rechargeable Zinc–Air Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study exploited the substitution doping of Mn and F in NiCo2O4 to activate and stabilize lattice oxygen, achieving a stable synergistic effect between AEM and LOM to enhance the intrinsic activity of the catalyst. The outstanding bifunctional properties enable its application as an anode catalyst in zinc–air batteries.

Desenvolvimento de nanomateriais contendo IR780 para aplicação na terapia do cancro [PDF]

open access: yes, 2018
Breast cancer is a leading cause of death among women. This reality is in part owed to the sub-optimal efficacy and non-specific toxicity of the currently available treatments. In this way, there is an urge need to develop innovative therapies for breast

Entropy‐Driven Innovations: Entropy Stabilized Oxides for High‐Performance Next‐Generation Lithium–Sulfur Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This article explores high‐entropy‐stabilized oxides (HEOs) as novel functional materials for addressing critical issues in lithium–sulfur (Li–S) batteries, including lithium polysulfide (LPS) shuttling, inadequate conductivity, and slow redox kinetics.

A Shock‐Tube Study of the HCl + M →$\to $ H + Cl + M (M = Ar) Rate Constant Using HCl Laser Absorption Near 3.3 µm

open access: yesInternational Journal of Chemical Kinetics, EarlyView.
ABSTRACT Hydrogen chlorine (HCl) is an important combustion intermediate during plastic (municipal waste) and composite propellant (aerospace) combustion, but the understanding of its high‐temperature chemistry is still evolving. In this study, the pyrolysis of 0.5% HCl in Ar was investigated behind reflected shock waves in a shock tube at temperatures
