Wetting of Cu-SiC Composite Material Modified by Nanosecond Laser Radiation and Liquid Spreading over It

open access: yesApplied Sciences, 2023
In the framework of this work, the surface properties of Cu-SiC composite material were studied when spreading micro- and nanoliter liquids. The Cu-SiC samples with a SiC content of 5 to 20 wt.% were fabricated by spark plasma sintering at temperatures ...

Study on the Navier boundary condition for flows with a moving contact line by means of molecular dynamics simulation

open access: yesNihon Kikai Gakkai ronbunshu, 2015
While the Navier boundary condition, which claims the proportionality between fluid slip velocity and wall shear stress (Qian et al., 2003, Bocquet and Barrat, 2007), was established by Thompson and Troian (1997) for a single-phase Newtonian fluid ...

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

open access: yesFEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Accumulative deformation law and control of compacted lateritic soil under coupled action of wetting and dynamic loading

open access: yesYantu gongcheng xuebao
To address the problem that the in-service lateritic soil subgrade is prone to wetting and excessive additional deformation under the combined effects of traffic loading in southern rainy areas of China, the static triaxial tests with different moisture ...

The role of the microscale contact line dynamics in the wetting behaviour of complex fluids

open access: yesArchives of Mechanics, 2015
The microscale morphology of the liquid-substrate contact line is studied experimentally in two well-known examples of dynamic wetting with complex fluids (namely, drop impact of dilute polymer solutions and spreading of superspreader surfactant ...

Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

open access: yesMolecular Oncology, EarlyView.
Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...

Shear Strength Deterioration of Compacted Residual Soils under a Wind Turbine due to Drying-Wetting Cycles and Vibrations

open access: yesAdvances in Civil Engineering, 2021
The soil beneath a wind turbine withstands not only environmental impacts but also continuous vibrations transmitted from the superstructure. This paper presents an experimental study of the deterioration characteristics of shear strengths of residual ...

Mycobacterial cell division arrest and smooth‐to‐rough envelope transition using CRISPRi‐mediated genetic repression systems

open access: yesFEBS Open Bio, EarlyView.
CRISPRI‐mediated gene silencing and phenotypic exploration in nontuberculous mycobacteria. In this Research Protocol, we describe approaches to control, monitor, and quantitatively assess CRISPRI‐mediated gene silencing in M. smegmatis and M. abscessus model organisms.

The skills required for transition to university and study in biological sciences: A student perspective

open access: yesFEBS Open Bio, EarlyView.
Bioscience students were asked for their opinions on the value and teaching of skills. 204 responded that teamwork, time management and study skills are necessary to reach University, that scientific writing, research, laboratory and presentation skills are taught effectively during their studies, while other skills are gained inherently through study ...

Simulation and evaluation method of dynamic wetting characteristics of dust suppression droplets on coal surface

open access: yesMeitan xuebao
Spraying dust suppression liquid on the coal surface is a common dust suppression method for coal-related industrial enterprises, and the wetting process of dust suppression droplets impacting the coal surface is of great significance to the dust ...
