Nanophotonics, Nanoelectronics and Nanosensor (N3) is part of International Photonics and OptoElectronics Meetings (POEM), launched by Wuhan National Laboratory for Optoelectronics (WNLO). POEM is a large-scale multi-disciplinary international conference in the field of photonics and optoelectronics. It aims to focus on the key techniques of scientific frontier and industry in the field of opto...

Molecular diffusion of polymer chains and low molecular weight constituents and impurities can be an important process in the formation and application of polymer composites. Molecular diffusion in polymer systems is a complex process which can be a strong function of temperature, concentration, polymer molecular weight and polymer morphology. During the last decade, significant advances have b...

Low-bandgap diketopyrrolopyrrole- and carbazole-based polymer bulk-heterojunction solar cells exhibit much faster charge carrier recombination kinetics than that encountered for less-recombining poly(3-hexylthiophene). Solar cells comprising these polymers exhibit energy losses caused by carrier recombination of approximately 100 mV, expressed as reduction in open-circuit voltage, and consequen...

The decrease in resonant frequency (-Deltaomega(r)) of a classical cantilever provides a sensitive measure of the mass of entities attached on its surface. This elementary phenomenon has been the basis of a new class of bio-nanomechanical devices as sensing components of integrated microsystems that can perform rapid, sensitive, and selective detection of biological and biochemical entities. Ba...

Polymers are large molecules consisting of a large number of small component molecules chemically linked together. They are made from constituent monomers through polymerization process. Polymers are unique materials in that they consist of a statistical distribution of chains of varying lengths, and each chain consists of monomer residues which affect its properties hence they require several ...

crosslinked poly(acrylic acid)s were prepared using two types of crosslinker by precipitation polymerization method in a binary organic solvent. n,n’-methylenebisacrylamide (mba) and polyethylene glycol dimethacrylate (pegdma-330) were used as low-molecular weight and long-chain crosslinkers, respectively. the effect of various types of crosslinkers on polymer characteristics (i.e., gel content...

OBJECTIVES The aim of this study was to evaluate the clinical performance of posterior, metal-free polymer crowns with and without a glass-fiber framework, in comparison to metal-ceramic crowns. METHODS After randomisation, 80 single crowns, manufactured from a newly designed polymer composite, were set in posterior teeth. Half of these received a glass-fiber framework, while half were prepar...

Identification of infectious bacteria responsible for biofilm-associated infections is challenging due to the complex and heterogeneous biofilm matrix. To address this issue and minimize the impact of heterogeneity on biofilm identification, we developed a gold nanoparticle (AuNP)-based multichannel sensor to detect and identify biofilms based on their physicochemical properties. Our results sh...

In this article, the influence of various vacancy defects on the Young’s modulus of carbon nanotube (CNT) - reinforcement polymer composite in the axial direction is investigated via a structural model in ANSYS software. Their high strength can be affected by the presence of defects in the nanotubes used as reinforcements in practical nanocomposites. Molecular structural mechanics (MSM)/finite ...

We develop a novel humidity nanosensor based on intercalated graphitic carbon nitride (g-C(3)N(4)) nanosheets fabricated by a facile thermal polymerization of common urea in the presence of LiCl as the intercalated guest under air and ambient pressure. The response and recovery times of an optimal nanosensor can reach ∼ 0.9 s and ∼ 1.4 s, respectively, which are superior to most of the traditio...
