Field trials and development of a hydrostatic pressure machine

, 2013
Hydrostatic Pressure Machines (HPM), are a class of hydropower energy converter designed to operate at sites with heads below 3 meters; sites receiving increasing interest as the demand for power from renewable energy sources grows.The HPM is a ‘Pressure

Identification of Parameters of the Hydrostatic Model of the Working Equipment Drive System of a Wheel Loader to Study the Effectiveness of the Energy Recovery System [PDF]

Problemy Mechatroniki
Research conducted on hybrid drive systems of working machines is quite often limited to simulation studies, omitting the experimental determination of the parameters of a real machine.

Pressure‐Tuned Superconducting Dome and Persistent Charge‐Density‐Wave Order in NdSeTe2

Advanced Science, EarlyView.
NdSeTe2 exhibits an unusual pressure‐tuned phase diagram in which charge‐density‐wave order does not disappear at optimal superconductivity. Instead, Raman spectroscopy reveals a transformation from long‐range to short‐range correlations that remain invisible to resistivity and persist across the entire superconducting dome.

A Novel Digitalized Hydrostatic Drive Solution for Modern Wind Turbine

, 2017
Gearbox is a concern in modern wind turbines, increasing the maintenance cost and therefore the cost of energy (COE). A hydrostatic transmission (HST) improves the turbine drivetrain reliability by using slightly compressible mineral oil as the working ...

Beyond‐Classical Ferroelectric Metamaterials: 3D‐Printed Planar Lattices With Programmable Electro–Thermo–Mechanical Coupling

Advanced Science, EarlyView.
Planar ferroelectric lattices with rationally‐tailored topology and polarization achieve programmable piezoelectric and pyroelectric properties. Analytical modeling, homogenization, and experiments collectively demonstrate enhanced and tunable longitudinal, transverse, and shear piezoelectric responses, together with substantially improved ...

Combinatorial Survey of Structural Phase Distribution and Magnetism in Fe‐Ge‐Te Composition‐Spread Thin Film Libraries

Advanced Electronic Materials, EarlyView.
ABSTRACT Magnetic 2‐dimensional (2D) van der Waals (vdW) materials have garnered tremendous attention. The vdW ferromagnet Fe5Ge1Te2 has a Curie temperature Tc of ≈ 270 K, which is tailorable by tuning the stoichiometry and the Fe deficiency to reach room temperature.

Mn‐Substituted Topological Phase Transition in Topological Insulator Pt2HgSe3

Advanced Electronic Materials, EarlyView.
ABSTRACT Topological materials have gained a significant interest in recent years due to their unique features, leading to topological insulators (TI), Dirac or Weyl semimetals, etc. The layered material Pt2HgSe3${\rm Pt}_2{\rm HgSe}_3$ is found to be a dual TI characterized by significant spin–orbit coupling and band inversion.
