Wire-feed laser additive manufacturing is an emerging fabrication technique capable of highly automated large-scale volume production that can reduce both material waste and overall cost while improving product lead times. Quality assurance is necessary for implementation into critical...

CO2 methanation is a promising route for converting CO2 into a marketable natural gas. The major challenge of this process is to enhance CO2 methanation catalytic activity at low temperature. This work showcases a supported-catalysts phase engineering strategy to overcome the challenge. We...

Ultrathin CdS nanosheets (NSs) are intriguing in photocatalytic hydrogen evolution. Severe photo-corrosion and low visible light utilization, however, impair their applications. To solve this problem, a novel step-scheme (S-scheme) 2D CdS/W18O49 van der Waals (vdW) heterostructure with strong...

A newly-developed auxiliary braking system has been designed that integrates the heat exchange capability of a hydrodynamic retarder and the rapid response of a hybrid control system. However, developing a mathematic method for predicting the coupling relationship between control information and...
