The Vegan Villain Sets Out to The End of Summer: Functionalized Coatings as Biohybrid UV‐Sensors

Advanced Materials Interfaces, EarlyView.
This study introduces biohybrid coatings incorporating E. coli biomass expressing photoconvertible fluorescent proteins as UV‐A responsive elements. Upon irradiation at 400 nm, the coatings exhibit an irreversible fluorescence shift from green to red within 15 min. Notably, the photoconversion capability is retained after >1 year of storage.

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

Laser‐Based Solidification of Cermets/Cemented Carbides: Processing‐Microstructure‐Property Relationships

Advanced Materials Technologies, EarlyView.
Recent research on laser‐processed cermets and cemented carbides highlights significant advancements, yet a notable paucity of studies and persistent challenges remain. Efforts are increasingly focused on developing low‐cost, environmentally friendly cermets as alternatives to conventional materials.

TADF‐Emitting Dendrimers for Scalable Bar‐Coating Fabrication of Light‐Emitting Electrochemical Cells

Advanced Materials Technologies, EarlyView.
TADF‐emitting dendrimers promise to enable scalable solution‐based fabrication of efficient electroluminescent devices by the virtue of an attractive set of properties. Here, we report on how light‐emitting electrochemical cells, comprising the TADF‐dendrimer tBuCz2m2pTRZ, can be fabricated by scalable bar‐coating under ambient air and deliver uniform ...

Mine disaster and mine rescue training courses in modern academic mining engineering programmes

, 2014
The mining industry worldwide is currently facing a significant restructuring process. In most underground mines, widespread mechanization of the mining processes increases production while reducing staff numbers. At the same time, mining depths as well as the lateral spread of the mine workings are increasing.

Digital Mine Research and Practice Based on Mining and Metallurgy System Engineering [PDF]

Frontiers of Engineering Management, 2016
Iron ore is necessarily basic raw material for industrialization and urbanization and related to the industrial distribution and development programming. The lean iron ore resource in our country is high-cost and low-efficiency, which cannot meet the demand of iron and steel industry, and even endanger the safety of industrial economy.
