Influence of Bernoulli′s Speed-reduced Oil Cavities on the Friction Characteristics of Hydrostatic Bearings

Journal of Harbin University of Science and Technology
In order to solve the problem of insufficient bearing capacity of hydrostatic thrust bearings at high speed, a pendulum shaped oil lifting structure is added in the double rectangular oil cavity and this paper takes the slope-shaped and the ordinary ...

A Versatile Engineering Platform for the Fabrication of Prosthetic Venous Valves Using Electrospinning

Advanced Healthcare Materials, EarlyView.
Percutaneous prosthetic venous valves are fabricated by embedding stents in an electrospun matrix that extends luminally to form leaflets. The design shields leaflets from hyperplastic cells, isolates struts from blood contact, and avoids discrete anchoring points.

UNIVERSAL STAND FOR STUDYING SEALING AND BEARING UNITS OF COMPRESSOR MACHINES [PDF]

Avtomobilʹnyj Transport (Harʹkov), 2018
The proposed stand is designed to test sealing and bearing units of various types, because these units, regardless of their type, require almost the same auxiliary stand systems, as well as practically the same measurement system.

UTact: Underwater Vision‐Based Tactile Sensor with Geometry Reconstruction and Contact Force Estimation

Advanced Robotics Research, EarlyView.
Embedded flexible sensing technologies advance underwater soft robotics, yet most systems still suffer from hysteresis and limited perceptiveness. Instead, vision‐based tactile sensors provide reliable and rapid feedback essential for complex underwater tasks.

Cells Dynamically Adapt Their Nuclear Volumes and Proliferation Rates During Single to Multicellular Transitions

Advanced Science, EarlyView.
It is currently not well understood how cells regulate basic properties, e.g., volume and mechanics within dense multicellular environments like tumors. Here, we show that different cell types of cancer and also normal cells largely decrease their nuclear and cellular volumes in emerging cell clusters and that this is partly driven by cell cycle shifts.

Thermohydrodynamic Lubrication Model Applicable to a Slipper of Swashplate Type Axial Piston Pumps and Motors (Effects of Operating Conditions)

Tribology Online, 2010
A thermohydrodynamic lubrication (THL) model of a hybrid (hydrostatic and hydrodynamic) thrust bearing is developed. It is applicable to a slipper of swashplate-type axial piston pumps and motors.

Methane Pyrolysis Performance in Catalytic Molten Media for Hydrogen Production From the Perspective of Bubble Column Reactor Design and Configuration

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In the hydrogen production routes from natural gas (methane), methane pyrolysis offers a cleaner option than the established steam methane reforming by producing CO2‐free hydrogen. However, in fixed bed reactors over solid catalysts, this technology experiences rapid catalyst deactivation due to carbon (coke) deposition encapsulating its ...

Dynamics of bubble absorption over porous membranes in an immersed medium

Droplet, EarlyView.
The dynamics of a bubble interacting with a flat, porous superhydrophobic membrane underwater has been illustrated. Abstract Porous superhydrophobic (SHP) membranes are gaining considerable attention due to their excellent underwater absorption and drag reduction properties. They exploit the Cassie‒Baxter state of wetting to remove the bubble in a fast

Development of rotary table grinding machine for large diameter Si wafers (1st report: Performance investigation of water hydrostatic rotary table)

Nihon Kikai Gakkai ronbunshu, 2016
Increasing of Si wafer diameter from φ300 mm to φ450 mm is required to enhance productivity of semiconductor devices. The authors developed a high stiff rotary grinding machine, which consists of a rotary table system and a wheel spindle system.

Slip versus dilation tendency parameter space as a tool for prospecting structurally controlled geothermal systems in greenfield: insights from the greater Ruhr region

Deep Underground Science and Engineering, EarlyView.
This study highlights that with the static and time‐dependent evolution of slip versus dilation tendency parameter space, structurally controlled deep geothermal systems can be selected within areas of higher permeability and lower seismic hazard. Abstract Faults play a vital role in the Earth's hydraulic system by facilitating fluid flow when dilating
