MXene‐Based Electrocatalysts for Sustainable Nitrogen Conversion: From Ammonia Oxidation to Nitrogen and Nitrate Reduction

Advanced Materials Interfaces, EarlyView.
This review compares MXene‐based electrocatalysis for ammonia oxidation, nitrogen reduction, and nitrate reduction, highlighting reaction‐dependent differences in catalytic performance and stability. MXenes are generally more compatible with cathodic nitrogen and nitrate reduction, whereas anodic ammonia oxidation raises stability concerns.

Study on development and properties of ceramic metal bond CBN block

Jin'gangshi yu moliao moju gongcheng, 2020
Resin bond wheels are mainly used for rail grinding, which have problems such as low material removal rate and high grinding temperature. Therefore, a new ceramic-metal bond CBN block was developed by using brazed super-hard abrasive technology.

Wood‐Derived Nanocellulose‐Biocarbon Fresnel‐Zone Plate Lenses for Sub‐THz Frequency Applications

Advanced Materials Technologies, EarlyView.
Wood‐derived nanocellulose and lignin‐based biocarbon were combined to fabricate fully bio‐based Fresnel zone plate (FZP) lenses for sub‐terahertz frequencies. These sustainable FZP lenses exhibit low dielectric loss and high directivity, achieving performance comparable to that of metallic references, and remain functional under environmental stress ...

Zero‐Waste Manufacturing of Ophthalmic Lenses by Direct Fluidic Shaping in Arbitrary Domains

Advanced Materials Technologies, EarlyView.
Conventional ophthalmic lens manufacturing discards up to 97% of material through subtractive processes. The Cookie Cutter algorithm extends Fluidic Shaping to arbitrary rim geometries. The framework prescribes a spatially varying boundary height that, under neutral buoyancy and surface tension, shapes curable polymer into spherocylindrical lenses that
