Compression and water retention behavior of saline soil improved by MICP combined with activated carbon.
Sci Rep

Department of Civil and Smart Construction Engineering, Shantou University, Shantou, 515063, Guangdong, China.
Saline soil is widely distributed in China and poses significant challenges to engineering construction due to its harmful effects, such as salt heaving, dissolution collapse, and frost heaving. The Microbial-Induced Calcite Precipitation (MICP) method is an emerging environmental-friendly modification that can reduce or eliminate the environmental and engineering hazards of saline soil. To verify the feasibility of the MICP method for improving the properties of saline soil, laboratory tests were conducted to study the effects of salt content, activated carbon content and freeze-thaw cycles on the compression and water retention behavior of MICP modified saline soil.

Lubricants are pivotal in mitigating friction and wear between surfaces, ensuring seamless movement of solid objects. However, the predominant use of petroleum-based lubricants in the automotive and industrial ssectors raises substantial concerns for future energy security. The exploration of vegetable oils as an alternative lubricant in the automotive industry was motivated by the depletion of fossil fuels and escalating environmental concerns.

This study presents an innovative methane gas sensor design based on anti-resonant hollow-core fiber (AR-HCF) technology, optimized for high-precision detection at 3.3[Formula: see text]. Our numerical analysis explores the geometric optimization of the AR-HCF's structural parameters, incorporating real-world component specifications.

Department of Anatomy, Faculty of Science, Mahidol University, 272 Rama VI Road, Ratchathewi, Bangkok, 10400, Thailand.
SARS-CoV-2, the cause of COVID-19, primarily targets lung tissue, leading to pneumonia and lung injury. The spike protein of this virus binds to the common receptor on susceptible tissues and cells called the angiotensin-converting enzyme-2 (ACE2) of the angiotensin (ANG) system. In this study, we produced chimeric Macrobrachium rosenbergii nodavirus virus-like particles, presenting a short peptide ligand (ACE2tp), based on angiotensin-II (ANG II), on their outer surfaces to allow them to specifically bind to ACE2-overexpressing cells called ACE2tp-MrNV-VLPs.

Faculty of Physics and Applied Computer Science, AGH University of Krakow, al. Mickiewicza 30, 30-059, Kraków, Poland.
The concept of the symplectic covariance property of the Wigner distribution function and the symplectic invariance of the Wigner-Rényi entropies has been leveraged to estimate the interaction time of the moving quantum state in the presence of an absolutely integrable time-dependent potential. For this study, the considered scattering centre is represented initially by the Gaussian barrier. Two modifications of this potential energy are considered: a sudden change from barrier to barrier and from barrier to well.
