Studies on the use of supercritical ammonia for ceramic nitride synthesis and fabrication [PDF]

open access: yes
The extractability of ammonia halides (including ammonium thiocyanate) formed as byproducts from the synthesis of Si(NH)2 via ammonolysis of the corresponding silicon tetrahalides using supercritical NH3 as the extraction medium was investigated.

Photosystem II‐Carbon Nitride Photoanodes for Scalable Biophotoelectrochemistry

open access: yesAdvanced Materials, EarlyView.
A spray‐freeze method is developed to fabricate large‐area (up to 33 cm2) macroporous carbon nitride photoanodes integrated with photosystem II enzymes for biophotoelectrochemical systems. The photoanodes reach a Faradaic efficiency of 93.5% for O2 evolution.

Temperature structure and emergent flux of the Jovian planets [PDF]

open access: yes
Long path, low temperature, moderate resolution spectra of methane and ammonia, broadened by hydrogen and helium, are used to calculate non-gray model atmospheres for the four Jovian planets.

Full Crystallographic Imaging of Hexagonal Boron Nitride Monolayers with Phonon‐Enhanced Sum‐Frequency Microscopy

open access: yesAdvanced Materials, EarlyView.
A nonlinear optical microscopy technique is introduced that enables rapid imaging of hexagonal boron nitride monolayers, which are usually optically invisible. The nonlinear mixing of mid‐infrared and visible laser pulses enables full crystallographic imaging through phase‐resolved sum‐frequency generation microscopy, where the resonant excitation of a

Revealing How Acid Sites Enhance the Electrocatalytic Glycerol Oxidation Performance on Pt Loaded Zeolite‐Carbon Composite Materials

open access: yesAdvanced Materials, EarlyView.
In the work reported herein, the catalytic effects of acid sites on electrocatalytic glycerol oxidation reaction are investigated by using a novel catalytic material system that integrates Pt metal sites with acidic Al sites. Abstract The catalytic role and function of acid sites in solid acid catalysts, such as zeolites, are well understood in the ...
