MOFs and COFs in Electronics: Bridging the Gap between Intrinsic Properties and Measured Performance

Advanced Functional Materials, EarlyView.
Metal‐organic frameworks (MOFs) and covalent organic frameworks (COFs) hold promise for advanced electronics. However, discrepancies in reported electrical conductivities highlight the importance of measurement methodologies. This review explores intrinsic charge transport mechanisms and extrinsic factors influencing performance, and critically ...

Rapid Sintering of Porous Organic Polymer Powders Into Mechanically Strong Monoliths for Efficient CO2 Capture

Advanced Functional Materials, EarlyView.
Spark plasma sintering enables rapid processing of porous organic polymer (POP) from fine powders to a freestanding and mechanically robust monolith. The sintering process retains the CO2 adsorption capacity and CO2/N2 selectivity, making the monolith more suitable as a solid sorbent for practical carbon capture applications.

Hydraulic drive boom lifting mechanism

IOP Conference Series: Materials Science and Engineering, 2019
The paper presents the calculation of the pressure of the hydraulic cylinder of the boom at the inlet to the throttle, which regulates the speed of lowering the boom with a load, which provides a non-cavitation operation mode of the hydraulic drive. The pressure calculation takes into account the change in the angular acceleration of the boom with a ...

GeAl2‐2xFe2xO3(OH)4 Nanotubes: New Electrocatalyst for Oxygen Evolution Reaction

Advanced Functional Materials, EarlyView.
Fe‐doped imogolite nanotubes are synthesized via a one‐step hydrothermal method with varying Fe substitution ratios x. Structural and spectroscopic analyses confirm homogeneous Fe incorporation while preserving tubular shape. Optimal doping at x = 0.05 enhances optical absorption, narrows band gap, reduces charge transfer resistance, and significantly ...

Hydraulic Stepper Drive - Conceptual Study, Design and Experiments

, 2016
Positionsgeregelte hydraulische Antriebe werden eingesetzt, wenn eine hohe Kraftdichte, schnelles Ansprechverhalten und ein kompaktes Design gefordert sind. Die dynamischen Anforderungen und hohen Genauigkeiten können zurzeit nur über Servo-Ventile in Kombination mit einer Regelung erreicht werden. Die Nachteile dieser Technologie sind die hohen Kosten
