Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

FEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Hyperosmotic stress‐induced redistribution of pre‐mRNA cleavage factor I subunits is associated with shifts in alternative polyadenylation

FEBS Open Bio, EarlyView.
Hyperosmotic stress triggers the relocation of the CFIm complex from the nucleus to the cytoplasm. This shift creates a nuclear ‘stoichiometric bottleneck’, limiting CFIm availability for mRNA processing. Consequently, specific mRNAs like NUDT21 and DICER1 undergo targeted 3′UTR shortening, demonstrating how spatial protein dynamics drive rapid ...

Influence of Platen Deformation Compensation on Motion Error of Hydrostatic Guideways

IEEE Access
The deformation of a pressure plate induced by oil film pressure is unavoidable in hydrostatic guideways, and the fluid–structure interaction between the oil film and the supporting structure significantly affects motion accuracy.

Oil Film and Pressure Characteristics of the Friction Pair

OALib, 2018
In order to improve the friction performance of the valve plate and improve the oil film bearing capacity of the valve plate, the influence of the fluid-solid coupling on the performance of the oil film of the valve plate was studied. The lubrication characteristics of the surface texture of the valve plate was studied systematically based on the ...

Experimental Evaluation of 100Cr6 Steel Microindented Surfaces Under Lubricated Nonconformal Point Contacts

Advanced Engineering Materials, EarlyView.
The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.

Dynamic Behavior of Oil Film between Piston Ring and Cylinder Liner : Visualization of Oil Film Rupture and Measurement of Oil Film Pressure Using Simulating Rig

JSME international journal. Ser. C, Dynamics, control, robotics, design and manufacturing, 1995
In order to clarify the behavior of oil film between a piston ring and cylinder liner, pressure measurement and visualization of oil film are carried out simultaneously using a simulation rig. In this rig, the piston ring is simulated by a straight glass bar test piece and the cylinder by a reciprocating flat plate.

From Food to Power: Hydrogel Thermoelectrics for Ingestible Electronics

Advanced Functional Materials, EarlyView.
We introduce a fully edible thermoelectric–electrochromic platform that harvests heat from food and converts it into a visible color change. N‐type and p‐type hydrogel thermoelectric generators connected in series power anthocyanin‐based electrochromic displays, demonstrating the feasibility of safe, biodegradable, ingestible systems for on‐food ...

INFLUENCE OF LOAD AND SPEED CHANGE ON LUBRICATION PERFORMANCE OF LOW SPEED HEAVY DUTY BEARINGS

Jixie qiangdu, 2019
In order to study the lubricating property of low-speed heavy-duty bearing under the condition of different loads and speed, such as the oil film thickness, oil film pressure and changes of oil film velocity. Building model of fluid-structure interaction
