Creating polymers with tunable permittivitt and loss tangent simultaneously requires precise control of the conductive filler microstructure through process optimization. Carbon coated SiO2 (C@SiO2) nanoparticles in an epoxy matrix represent a suitable system for this challenge. ... En savoir plus

Noncollinear ultrasonic wave mixing is a powerful nondestructive evaluation (NDE) technique for localizing microscale material damage, as the amplitude of the generated mixed wave is a direct measure of localized material nonlinearity. Recent experimental work combined this technique ... En savoir plus

Graphene-coated optical fibers offer a compact route to fiber-based nonlinear switching by combining guided-wave interaction with graphene’s intensity-dependent optical absorption. However, early-phase design of these devices is poorly suited to full 3D optical-frequency simulation: ... En savoir plus

High-fidelity home audio design requires strict control over cabinet resonance, especially when fitting components into modern, tightly constrained spaces. Evaluating acoustic performance based on discrete elements within a given enclosure composition with varying stiffness is critical ... En savoir plus

Almost all industrial processes produce exhaust and use chemicals potentially harmful to humans. This is even more applicable for chemical industries whose primary raw materials and products may be detrimental to people’s health. As a result, people working or living nearby chemical ...

The importance of blood glucose monitoring for diabetics cannot be overemphasized. However, all current CGM methods utilize the use of needles for inserting sensors. The use of optical sensors looks promising since it promises to become both non-invasive and reliable. However, there are ... En savoir plus

Semiconductor quantum dots (QDs) play a critical role in next-generation optoelectronic devices, including high-efficiency lasers and light-emitting diodes (LEDs). This importance arises from the discrete energy levels of QDs and their tunable emission properties. For device engineers, ... En savoir plus
