Controlled Growth of Boron Nitride in Various Phases

Advanced Materials Interfaces, EarlyView.
Phase‐selective boron nitride growth is presented as a unified materials‐design problem across hexagonal, rhombohedral, cubic, and amorphous phases. By linking synthesis routes to thermodynamic stability, kinetic accessibility, surface diffusion, interfacial templating, and energetic activation, this review clarifies how bonding and stacking are ...

Experimental study on combustion characteristics of coal/NH3 in a flat flame burner

Meitan xuebao
To meet the “peak carbon and carbon neutrality” targets, the gradual reduction of coal-fired electricity generation through the co-firing of coal and NH3 has emerged as a new pathway to achieve carbon reduction.

Emission characteristics of a lean-premixed ammonia/natural-gas gas-turbine combustor and effect of secondary ammonia injection

Mechanical Engineering Journal, 2019
To develop an NH3/natural gas-fired gas-turbine combustor with minimal modifications to a natural gas-fired combustor, the effect of co-firing NH3 with natural gas on emission characteristics and combustion efficiency is investigated experimentally under

Probing the Architecture of Organic Heterojunctions Based on Zn(Salen)‐Type/Lu(Bis‐phthalocyanine) Complexes and Their Potential Application as Gas Sensors

Advanced Materials Interfaces, EarlyView.
Planar bilayer heterojunctions are fabricated from two molecular materials and compared to solution‐processed bulk heterojunctions. Raman spectroscopy and conductive AFM studies reveal the formation of conductive pillar‐like structures within a poorly conductive matrix.
