CHARACTERIZATION AND SIMULATION OF MACROSCALE MOLD-FILLING DEFECTS IN MICROMINIATURE POWDER INJECTION MOLDING

open access: yes, 2019
While micromolding with polymers has met with success, material homogeneity remains a critical issue in powder injection molding (PIM) because separation of the powder and binder results in defects in metal or ceramic microparts.

Gradient p‐p Orbital Hybridization in Bismuth‐Doped Crystalline Carbon Nitride for Dual‐Functional Carbon‐to‐Carbon Valorization

open access: yesEcoEnergy, EarlyView.
Schematic illustration comparing the charge transfer dynamics and catalytic reaction over the (left) pristine carbon nitride and (right) Bi‐doped carbon nitride photocatalysts. In the pristine system, random charge diffusion and rapid recombination limit catalytic efficiency. In contrast, the Bi‐doped system establishes a robust internal electric field

One‐Step Synthesis of Si–Graphene Heterostructures via in‐Flight Gas‐Phase Mixing for High‐Capacity Silicon‐Rich Anodes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A one‐step gas‐phase synthesis directly assembles amorphous Si nanoparticles with few‐layer graphene heterostructures via in‐flight mixing. Compositions with only 15 wt.% FLG deliver ~2800 mAh g−1 (Si + FLG) at 0.05 C and retain ~1400 mAh g−1 after 100 cycles at a high cycling rate of 1 C, enabled by a percolated, strain‐buffering graphene network that
