A Method for Optimizing Technical Parameters of the Vacuum Freeze-Drying Process [PDF]

open access: yesKemija u Industriji, 2014
Vacuum freeze-drying is a technique that makes a material dehydrate at low temperature and low pressure, and it has many merits. A control system is designed and developed based on a certain area freeze-drying machine.

Test stand system for vacuum chambers [PDF]

open access: yes, 1973
A test stand system for supporting test items in a vacuum chamber is described. The system consists of a frame adapted to conform to the inside of the vacuum chamber and supporting a central vertical shaft.

Thermodynamics of Fuzzy Spheres in PP-wave Matrix Model

open access: yes, 2004
We discuss thermodynamics of fuzzy spheres in a matrix model on a pp-wave background. The exact free energy in the fuzzy sphere vacuum is computed in the \mu -> \infty limit for an arbitrary matrix size N.

Matrix metalloproteinase‐9 regulates cell adhesion and membrane protrusive activity of ovarian cancer cells

open access: yesFEBS Open Bio, EarlyView.
Matrix metalloproteinase‐9 (MMP9) drives ovarian cancer progression. Using MMP9‐null cells (M9‐KO) created from ovarian cancer cells, we found MMP9 loss did not block Epidermal Growth Factor (EGF)‐driven E‐cadherin dissolution or EMT but delayed and reduced EGF‐driven membrane protrusions. Transient MMP9 re‐expression drove membrane protrusion.

Simulation of thermal and flow field in a large-scale vertical roll-to-roll PECVD chamber [PDF]

open access: yesAIP Advances
The distribution of gas flow and temperature fields plays a crucial role in influencing the uniformity and deposition rate of PECVD (plasma enhanced chemical vapor deposition) coating deposition processes.

Axial Casimir Force

open access: yes, 2019
Quantum fluctuations in vacuum can exert a dissipative force on moving objects, which is known as Casimir friction. Especially, a rotating particle in the vacuum will eventually slow down due to the dissipative Casimir friction.

YlmG1 is localized exclusively to the chloroplast envelope membrane and is involved in preprotein translocation in Arabidopsis thaliana

open access: yesFEBS Open Bio, EarlyView.
Cytosolically synthesized chloroplast preproteins are translocated across the outer and inner envelope membranes through translocons called TOC and TIC, respectively. In green algae and plants, the TIC core is composed of essential membrane proteins, Tic12, Tic20, and Tic214.

Construction and performance of high barrier films with SiOX/TPGDA/SiOX “sandwich” structure for water-oxygen barrier properties

open access: yesJournal of Aeronautical Materials
SiOX/TPGDA/SiOX sandwiched films are fabricated by roll-to-roll plasma vapor deposition (roll-to-roll PECVD) and roll-to-roll evaporation coating technology.
