Advanced Functional Materials, EarlyView.Monolithic UV‐ozone oxidation of Ta forms an ultrathin Ta2O5/TaOx bilayer enabling resistive switching with a vertical defect gradient. A stoichiometric surface layer over an oxygen‐deficient sublayer promotes localized filament nucleation near the top interface, enabling low‐voltage operation, and reduced cycle‐to‐cycle variability.

Advanced Functional Materials, EarlyView.Hierarchical coordination engineering redistributes Li+ from anion‐dominated pairing toward polymer‐mediated binding. Strong primary sites promote salt dissociation, while distributed secondary sites sustain dynamic hopping pathways. This coordination landscape couples ion flux with polysulfide conversion, suppresses transport‐conversion decoupling ...

Distribution of contact pressure in wheel–rail contact area
Wear, 2002Abstract The authors have recently assessed the feasibility of applying an ultrasonic technique for investigating contact problems between the wheel and rail. In particular, the size and shape of the contact area have been determined, obtaining good agreement between the experimental data and Hertz’s theory.

Contact area of the trapeziometacarpal joint
The Journal of Hand Surgery, 1999Eighteen cadaver hands were studied to determine the contact area of the trapeziometacarpal joint by using silicone rubber casts. Casting material was introduced into the trapeziometacarpal joint during several motions of the thumb and the contact location was observed. The ratios of the contact area to the total joint area were calculated. The contact

Area-Contact Haptic Simulation
2003This paper presents the haptic interaction method when the interaction occurs at several points simultaneously. In many virtual training systems that interact with a virtual object, the haptic interface is modeled as a point. However, in the real world, the portion interacting with real material is not a point but rather multiple points, i.e., an area.

The actual contact area in viscoelastic contact problems
Polymer Mechanics, 1972The effect of the viscoelastic properties of polymers on the formation of the actual contact area is analyzed with reference to a rod model of the rough surface. The proposed time dependence of the actual contact area has been verified experimentally by an optical method for surfaces with different finishes (▽ 4, ▽ 8) and for different materials ...

Contact Area and Thermal Contact Resistance in an Ideal Bolted Joint: Part 1 — Study of Contact Area
CAE/CAD and Thermal Management Issues in Electronic Systems, 1997Abstract The contact area at the interface of a bolted joint was investigated analytically, experimentally and numerically. Consideration was restricted to an ideal two-plate model for which the interface was perfectly flat. The two plates made circular contact under uniform axisymmetric normal loading.
