Light deflection and convection in diffusion experiments using holographic interferometry

, 2001
A study of the effect of light deflection during diffusion studies of ethanol into agarose gel using holographic laser interferometry is presented. Furthermore it also demonstrates how a diffusive flux could give rise to a convective flux in holographic ...

Reduced Graphene Oxide Transparent Electrodes Enabling Compact Soft Tunable Lenses

Advanced Functional Materials, EarlyView.
By spray‐coating an elastomeric membrane with reduced graphene oxide (rGO) at various surface densities, elastomeric actuators are manufactured. Electro‐mechano‐optical characterizations show the suitability of rGO as an effective material for compliant, semi‐transparent electrodes, enabling soft electrically tunable lenses with a compact form factor ...

Time-averaged cantilever deflection in dynamic force spectroscopy

, 2009
We theoretically and experimentally study a hitherto neglected effect in dynamic force spectroscopy. The time-averaged deflection of the cantilever and the frequency shift of its second flexural mode were measured for 11 oscillation amplitudes between 12.

Improving Predictive Accuracy in Surrogate Modeling of Plate Deflection through Physics-Informed Feature Engineering

Modeling, Control and Information Technologies
This work proposes a physics-informed feature engineering approach to improve the predictive accuracy of surrogate models for problems in solid mechanics. The prediction of the maximum deflection of a thin square plate under a uniform load is considered as a case study.

Conformal Metallosaccharide Hybrid Films for Protecting Wood Surfaces From Environmental Damage

Advanced Functional Materials, EarlyView.
Ti‐ribose hybrid films fabricated by molecular layer deposition form a conformal and uniform coating on wood surfaces, which provides water repellence, dimensional stability, and resistance to acidic and alkaline environments, while preserving the natural appearance.

Low‐Profile, High‐Gain GRIN RF Lenses via Multi‐Material Vat Photopolymerization

Advanced Functional Materials, EarlyView.
We investigate the opportunity of leveraging multi‐material vat photopolymerization printing to manufacture intricate lenses exhibiting permittivity gradients that can increase signal gain in transmitted radiofrequency signals in the X‐ and Ku‐bands. Lenses produced with more distinct low‐loss materials (up to 5) can deliver an 18 dB signal gain with a

El experimento de Rutherford en el contexto de la Historia y Filosofía de la Ciencia y sus implicaciones para los textos de Física

Revista de Enseñanza de la Física, 2016
This article has evaluated the presentation of Rutherford's experiment in 35 university level general physics textbooks, within a History and Philosophy of Science context. In general the textbooks ignore the importance of rivalry between two conflicting

Machine learning assisted prediction of dynamics in current-driven nested skyrmion bags

Communications Physics
Nested skyrmion bags are topological magnetic structures with tunable topological charge, offering potential for spintronic applications. Predicting their current-driven dynamics, particularly the skyrmion Hall angle, across diverse structural and ...

Long‐Term Hydrophilic, Anti‐Clotting, and Anti‐Fibrotic Dynamic Covalent Silicone‐Based Biomaterials

Advanced Healthcare Materials, EarlyView.
Dynamic covalent crosslinking of a Schiff‐base silicone elastomer with hydrazide‐functionalized polymers is demonstrated to improve the long‐term hydrophilicity as well as the anti‐fouling and anti‐clotting properties of PDMS implants. The hydrazone‐functionalized material prevents hydrophobic recovery, resists clotting, and significantly reduces ...
