Emission of pollutants into the air during exploration of coalbed methane
, 2018 Coalbed methane is usually utilized by gas well drilled from the surface. In order to increase the coefficient of methane exploration from coal seams, in a horizontal section of the well, hydraulic fracturing operations are applied.

Tailoring Phonon‐Driven Responses in α‐MoO3 through Isotopic Enrichment
Advanced Materials, EarlyView.ABSTRACT The implementation of polaritonic materials into nanoscale devices requires selective tuning of parameters to realize desired spectral or thermal responses. One robust material, α‐MoO3, an orthorhombic crystal boasting three distinct phonon dispersions, provides three polaritonic dispersions of hyperbolic phonon polaritons (HPhPs) across the ...

Advanced Materials, EarlyView.This project developed a smart bandage‐like patch (a microneedle array) for repairing diabetic bone damage. It intelligently senses signals from infection and inflammation, then releases its medicines in a specific, timed sequence: first an antibacterial agent, then an anti‐inflammatory agent, and finally growth factors.

Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization
Advanced Materials Interfaces, EarlyView.Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery

Advanced Materials Interfaces, EarlyView.An all‐in‐fiber broadband polarization photodetector is demonstrated by integrating a PdSe2/2H‐MoTe2 van der Waals heterostructure onto a fiber endface. The device exhibits broadband response spanning 532 nm to 1630 nm, a fast response time of 59 µs, and a polarization ratio of 1.99. This work demonstrates a promising hardware strategy for polarization
