Advanced Functional Materials, EarlyView.This work reports the self‐assembly of a pyrene derivative into two distinct nanostructures and their application in visible‐light photocatalysis. The two nanostructures exhibit completely different yet complementary photocatalytic activities, promoting either H2 or H2O2 evolution.

Diamond growth in premixed propylene-oxygen flames [PDF]
, 1995 Diamond film growth in low-pressure premixed propylene/oxygen flames is demonstrated. Well-faceted films are grown at a pressure of 180 Torr and a fuel/oxygen ratio of 0.47. Using propylene as the fuel may greatly improve the economics of flame synthesis

Acetylene-Accelerated Alcohol Catalytic CVD Growth of Vertically Aligned Single-Walled Carbon Nanotubes [PDF]
arXiv, 2008 Addition of only 1% of acetylene into ethanol was found to enhance the growth rate of singlewalled carbon nanotubes (SWNTs) by up to ten times. Since acetylene is a byproduct of the thermal decomposition of ethanol, this suggests an alternative fast reaction pathway to the formation of SWNTs from ethanol via byproducts of decomposition.

Advanced Functional Materials, EarlyView.High‐temperature requirements and complex synthesis limit the practical use of perovskite‐based metal exsolution catalysts. This study addresses these limitations by employing bead milling, enabling efficient metal exsolution at a significantly lower temperature (300 °C) from La0.6Sr0.4CoO3‐δ nanoparticles. Consequently, the catalytic mass activity for

Developing Cathode Films for Practical All‐Solid‐State Lithium‐Sulfur Batteries
Advanced Materials, EarlyView.The development of all‐solid‐state lithium‐sulfur batteries offers higher specific energies and lower costs compared to state‐of‐the‐art Li‐ion batteries. However, a lack of mechanistic understanding hinders advancement. This review analyzes key electrode parameters, evaluates progress in enhancing ion/electron percolation, and addresses ...
