Rationally Designed Bilayer Passivation Strategy for High‐Performance Vacuum‐Processed Perovskite Solar Cells

Advanced Functional Materials, EarlyView.
A bilayer “Anchor‐and‐Seal” passivation strategy using EDAI2 and 4MeO‐PEAI effectively mitigates surface defects in vacuum‐processed perovskite films through synergistic hydrogen bonding and Lewis base coordination. This approach optimizes interfacial energy alignment and suppresses non‐radiative recombination, enabling vacuum‐deposited p‐i‐n ...

Solution‐Processed Two‐Dimensional Indium Oxide on Sodium‐Embedded Alumina for Reconfigurable Optoelectronic Synaptic Transistors

Advanced Functional Materials, EarlyView.
Wafer‐scale two‐dimensioanl In2Se3 oxidized into InOx on sodium‐embedded beta‐alumina enables multifunctional reconfigurable electronics. Sodium ions accumulate within distinct spatial distribution under drain‐controlle and gate‐controlled operation. Drain‐control operation gives controllability of ultraviolet‐driven optoelectronic synaptic conductance

Contact Force Decomposition Using Contact Pressure Distribution

IEEE Robotics and Automation Letters, 2017
Many robotics applications involving contact with objects require the decomposition of an external force measured by a force sensor into its normal and shear components. In this paper, we present a general and effective contact force decomposition method based on the contact pressure distribution.

The Contact Patch Test for Linear Contact Pressure Distributions in 2D Frictionless Contact

, 2011
It is well known that the classical one-pass node-to-segment algorithms for the enforcement of contact constraints fail the contact patch test. The situation is particularly critical when using the penalty method. In a recent study, the authors proposed a modified one-pass node-to-segment algorithm able to pass the contact patch test also in ...

Endolaryngeal contact pressures

Journal of Voice, 1998
In this work, we present a new method for in vivo endolaryngeal contact pressure measurement with a miniature pressure transducer. Using this methodology, contact pressures can be measured during videoendoscopy at different locations between the artyenoids and also at various locations along the membranous vocal folds.

Steady State Contact Pressures in Electrical Contacts

IEEE Transactions on Components, Hybrids, and Manufacturing Technology, 1988
The development of a numerical analysis is outlined for the thermoelastic effects in stationary electrical contacts. The steady-state pressure distribution at the contact, the change of contact area, and the separation of the contacting bodies are calculated. The temperature field obtained by Y.G. Yune and M.D.

Pressure Dependence of the Contact Angle

The Journal of Physical Chemistry B, 2007
When a liquid and its vapor contact a smooth, homogeneous surface, Gibbsian thermodynamics indicates that the contact angle depends on the pressure at the three-phase line of an isothermal system. When a recently proposed adsorption isotherm for a solid-vapor interface is combined with the equilibrium conditions and the system is assumed to be in a ...

Effects of pressure on contact dermatitis

American Journal of Industrial Medicine, 1985
AbstractIn human volunteers, firm pressure was applied to deformable plastic chambers containing (1) chemical irritants, (2) glass fibers, and (3) selected allergens to which the subjects were sensitive.Pressure variably intensified irritant dermatitis and strikingly enhanced fiberglass dermatitis. Pressure did not influence allergic contact dermatitis.

Contact Pressure in Honing

Russian Engineering Research, 2020
Contact in the honing of cylindrical holes is simulated. Nonlinear behavior of the mean contact pressure and the transfer coefficient is observed. These factors depend on the applied force and the surface relief, as well as the materials used in the tool and workpiece.
