We show theoretically that it is possible to trap light in a microresonator structure by use of four-wave mixing. The efficiency of the parametric process is substantially increased by the high group delay of light inside the structure. The energy that is trapped has a half-life of approximately 500 ps in the presence of both linear and nonlinear loss in the channel waveguides and resonators. We also demonstrate that the energy can be extracted from the cavity with a similar process.

Cardiac amyloidosis (CA) is an infiltrative disease that results from the deposition of amyloid fibrils in the myocardium, resulting in restrictive cardiomyopathy. The amyloid fibrils are predominantly derived from two parent proteins, immunoglobulin light chain (AL) and transthyretin (ATTR), and ATTR is further classified into hereditary (ATTRv) and wild-type (ATTRwt) based on the presence or absence, respectively, of a mutation in the transthyretin gene. Once thought to be a rare entity, CA is increasingly recognized as a significant cause of heart failure due to improved clinical awareness and better diagnostic imaging.

Multifunctional devices based on van der Waals heterojunctions have drawn significant attention owing to their portable size, low power consumption and various application scenarios. However, high fabrication equipment requirements, complex device structures and limited operating conditions hinder their potential value. Herein, multifunctional UV photodetect-memristors based on GaS/graphene/GaN van der Waals heterojunctions area selective deposition have been proposed for the first time.

Accurate determination of dielectric properties and surface characteristics of two-dimensional (2D) perovskite nanosheets, produced by chemical exfoliation of layered perovskites, is often hindered by exfoliation agent residues such as tetrabutylammonium (TBA). This study investigates the effect of ultraviolet (UV) light exposure duration on the removal of TBA residues from 2D Ca2NaNb4O13- nanosheets deposited on silicon substrates via Langmuir-Blodgett method using atomic force microscopy (AFM). Nanoscale adhesion forces between silicon AFM tips and nanofilms exposed to UV light for 3, 12, 18, and 24 hours were measured.

One of the primary challenges is how to suppress light reflections across an entire metasurface. Such reflections are the source of undesirable noise, so their suppression is especially critical in imaging and optical communication applications.

In this study, novel polyaniline-coated perovskite nanocomposites (PANI@CoTiO and PANI@NiTiO) were synthesized using an in situ oxidative polymerization method and evaluated for the photocatalytic degradation of Rhodamine B (RhB) a persistent organic pollutant. The nanocomposites displayed significantly enhanced photocatalytic efficiency compared to pure perovskites. The 1%wt PANI@NiTiO achieved an impressive 94% degradation of RhB under visible light after 180 min, while 1wt.
