Ultrathin Cellulose Nanofiber Assisted Ambient‐Pressure‐Dried, Ultralight, Mechanically Robust, Multifunctional MXene Aerogels

Advances in Materials, 2022
Ambient‐pressure‐dried (APD) preparation of transition metal carbide/nitrides (MXene) aerogels is highly desirable yet remains highly challenging. Here, ultrathin, high‐strength‐to‐weight‐ratio, renewable cellulose nanofibers (CNFs) are efficiently ...

Pressure-induced boron clathrates with ambient-pressure superconductivity

Journal of Materials Chemistry C, 2021
A pressure-induced boron clathrate LaB8 structure exhibits potential superconductivity of 20 K at ambient pressure. This current result provides a new route to find high-Tc cage superconductors at low-pressures.

Ambient-pressure synthesis of ethylene glycol catalyzed by C60-buffered Cu/SiO2

Science, 2022
Bulk chemicals such as ethylene glycol (EG) can be industrially synthesized from either ethylene or syngas, but the latter undergoes a bottleneck reaction and requires high hydrogen pressures.

Microstructure of cement paste subject to ambient pressure carbonation curing

, 2021
This study investigated the microstructure of ordinary Portland cement paste subject to early age ambient pressure carbonation curing in a flexible enclosure. The high-pressure carbonation at 5 bar and the normal hydration were used as references.

Mixed elastohydrodynamic analysis of a coupled journal-thrust bearing system in a rotary compressor under high ambient pressure

Tribology International, 2021
The hermetic rotary compressor’s bearings, including the thrust bearing, the main and sub bearings, work together under high ambient pressure. The thrust bearing works under light axial loads, but sever wear is found, which may be related to the ...
