Enhancing Plateau Capacity of Binder‐Free and Self‐Supported Napkin‐Based Hard Carbon Anodes for Sodium‐Ion Batteries Via a Pre‐Oxidation Modulation Strategy

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Precise regulation of preoxidation time and carbonization temperature in biomass napkin‐derived hard carbon generates abundant closed pores and ultramicropores, significantly enhancing the capacity in the low‐potential plateau region (the high plateau capacity of 266 mAh g−1) and thereby achieving highly reversible sodium‐ion storage (395 mAh g−1 at 30

Boosting Photocatalytic H2O2 Synthesis Over HKUST‐1 MOFs‐Derived Hollow HKUST‐1@CuFePBA@CuS Heterojunctions

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Photoelectron transfer mechanism and photocatalytic O2‐to‐H2O2 reduction process over hollow HS@CuFe@CuS heterojunction photocatalysts. Recently, photocatalytic synthesis of H2O2 has received much attention. However, the photocatalytic activity of photocatalysts is generally limited due to multiple factors, such as insufficiency of photoelectrons, low ...

Sustainable Upcycling of Office Waste Paper Into Cobalt/Carbon Aerogels for Highly Efficient Microwave Absorption

open access: yesElectron, EarlyView.
Co/C aerogels (Co/CAs) are successfully fabricated with office waste paper (OWP) as the raw material by loading ZIF‐67 crystals. The optimal sample exhibited an effective absorption bandwidth of 5.6 GHz, which outperforms many biomass‐derived microwave absorbing materials.

Beeswax: Food and beyond

open access: yesFood Biomacromolecules, EarlyView.
Abstract Honeybees (Apis mellifera L.) are an important class of insects that are the most beneficial in terms of economy. Beeswax is the second most important bee products after honey. Its commercial importance is due to its antimicrobial, antioxidant, anti‐inflammatory and antiseptic as well as regenerative properties.

Structural design and property regulation of organic polymers for photocatalytic synthesis of H2O2

open access: yesInfoScience, EarlyView.
Photocatalytic synthesis of H2O2 offers a sustainable approach. Photocatalytic efficiency depends critically on interfacial electron transfer kinetics and spatial charge separation. Herein, we systematically analyze key factors governing photogenerated carrier dynamics and propose engineered strategies to optimize performance, thereby providing design ...

Interplay of plasma-induced and fast thermal nonlinearities in a GaAs-based photonic crystal nanocavity

open access: yes, 2009
We investigate the nonlinear response of GaAs-based photonic crystal cavities at time scales which are much faster than the typical thermal relaxation rate in photonic devices.

Application Research of Microstructured Flexible Sensors in Rehabilitative Wearable Sensing

open access: yesiNew Medicine, EarlyView.
ABSTRACT Flexible sensors enable the continuous, real‐time monitoring of the physiological and movement signals of patients, providing data support for precise rehabilitation strategies and playing a crucial role in rehabilitation medicine. However, traditional rigid sensors are often incompatible with dynamic body contours due to their high material ...
