Nb2C‐Reinforced Hydrogel Microneedle as Dual ROS‐Scavenging Platform to Promote Diabetic Wound Healing

Advanced Healthcare Materials, EarlyView.
An advanced microneedle patch integrating niobium carbide nanosheets and curcumin is engineered for diabetic wound healing. The system enables dual ROS scavenging and NIR‐enhanced antimicrobial activity, effectively rebalancing the oxidative microenvironment, promoting macrophage repolarization and angiogenesis, and accelerating full‐thickness wound ...

Cr2AlC: A High‐Temperature Transparent Conducting Ceramic

Advanced Materials Interfaces, EarlyView.
The high‐quality epitaxial Cr2AlC(0001) layer combines a low resistivity of 42.5 µΩcm, 84% optical transmittance at 900 nm, and thermal stability up to 800–1100°C. It stands out as an excellent high‐temperature transparent conductor with a negligible resistivity size effect, exceptional scaling (ρoλ < 3 × 10−16 Ωm2), and a figure of merit of 0.004 Ω−1.

NIOBIUM CARBIDE COATING OF GRAPHITE TUBES [PDF]

, 1958
Graphite tubes having a length-to-bore-diameter ratio of 430 were coated on the inside with uniform adherent layers of niobium carbide in thicknesses of 0.002 and 0.004 in. Intimate conformity to the graphite surface and improved uniformity were obtained by reacting NbCl/sub 5/ vapor with the graphite under pressuretemperature conditions ...
