Aerospace engines ingest small particles when operating in a particulate-rich environment, such as sandstorms, atmospheric pollution, and volcanic ash clouds. These micron particles enter their cooling channels, leading to film-cooling hole blockage and thus thermal damage to turbine blades made of...

To produce a large amount of soluble cyclophilin A (CypA) protein, the recombinant pRSET -CypA plasmid was transferred into E. coli BL21. Using the 2×YT culture medium, the medium compositions of carbon source, nitrogen source and ampicillin concentration were optimized, and the effects of inoculum...

ABSTRACT Aerobic methanotrophy, mainly carried out by methane-oxidizing bacteria (MOB) in freshwater systems, plays a crucial role in reducing methane (CH4) emissions and serves as an additional carbon source (methane-derived carbon) that supports the development of microbial food loops. However, ho...

The organic volatile compound gases (VOCs) emitted by the rubber running tracks in the park pose a threat to human health. Currently, the challenge lies in how to detect the VOC gas concentration to ensure it is below the level that is harmful to human health. This study developed a low-power aceton...

The three-cylinder valve-controlled energy recovery device (TC-ERD) employs “liquid piston” instead of physical piston, which improves operational safety but also reduces the volumetric efficiency of the pressure exchange cylinder. Herein, a method of feed seawater overflush is proposed, which can i...

Hen’s eggs are delicious in taste, have high nutritional value, are easily absorbed by the human body, being an important food source for humans and a low-cost raw material for food processing. However, eggs are one of the most common food allergens, and the incidence of egg allergy among infants an...

Overuse of tert-butylhydroquinone (TBHQ) as a food antioxidant has the potential to pollute the environment and threaten human health. Therefore, it is imperative to develop precise and rapid methods to detect TBHQ in food products. In this study, Fe- and Mn-doped Prussian blue analogs (FeMn-PBAs) w...

Unsharp measurement is a unique type of measurement which provides a tradeoff between information gain and state disturbance. Such measurement is a crucial method in quantum theory and shows potential in various applications. We propose a device-independent scheme for certifying unsharp measurements...
