Mid-infrared tunable absorber based on an Ag/SiO/VO/Ag/VO multilayer structure and its molecular sensing capability.

We present a design of middle-infrared modulation absorbers based on vanadium dioxide (VO). By using the electron beam evaporation technique, the Ag/SiO/VO/Ag/VO multilayer structure can achieve double band strong absorption in the mid-infrared, and dynamically adjust the absorption performance through VO. The simulation results demonstrate a remarkable absorption rate of 91.

Thin layer chromatography coupled with surface enhanced Raman scattering for rapid separation and on-site detection of multi-components.

The separation and detection of multi-component mixtures has always been a challenging task. Traditional detection methods often suffer from complex operation, high cost, and low sensitivity. Surface enhanced Raman scattering (SERS) technique is a high sensitivity, powerful and rapid detection tool, which can realize the specific detection of single substance components, but it must solve the problem that multi-component mixtures cannot be accurately determined.

MicroRNA schizophrenia: Etiology, biomarkers and therapeutic targets.

The three sets of symptoms associated with schizophrenia-positive, negative, and cognitive-are burdensome and have serious effects on public health, which affects up to 1% of the population. It is now commonly believed that in addition to the traditional dopaminergic mesolimbic pathway, the etiology of schizophrenia also includes neuronal networks, such as glutamate, GABA, serotonin, BDNF, oxidative stress, inflammation and the immune system. Small noncoding RNA molecules called microRNAs (miRNAs) have come to light as possible participants in the pathophysiology of schizophrenia in recent years by having an impact on these systems.

An atomic-layer NiO-BaTiO nanocomposite for use in electrochemical sensing of serotonin.

The NiO films were deposited on the surface of BaTiO (BTO) by atomic layer deposition (ALD). The thickness of NiO film was controlled by the number of ALD cycles, which the optimum number of ALD cycles were 400 cycles. The morphology of NiO-BTO nanocomposite was observed by x-ray diffraction, scanning electron microscope, and transmission electron microscopy.
