Based on the TiN square-ring structure, a spectrally selective absorber for solar thermal absorption is proposed announcing an average of 95.69% in major spectral region (280 nm∼2500 nm). When wavelength exceeds 2500 nm, declines rapidly and decreases to 40.4% at 4000 showing excellent selectivity. As incident angle TE or TM polarized wave varies range 0∼60 degrees, maintains more than 90% effi...

Laser micro-Raman spectroscopy is an ideal tool for assessment and characterization of various types of carbon-based materials. Due to its special optical properties (CrN) coated stainless steel substrates. NCD films have been investigated by laser micro-Raman spectroscopy. The fingerprint of diamond based materials is in the spectral region of 1000-1600 cm-1 in the first order of Raman scatter...

Abstract We report generation of spectrally bright vacuum ultraviolet (VUV) and deep UV (DUV) coherent radiations at the wavelengths 192 nm, 198 nm 204 nm. These DUV/VUV originate from resonant four-wave mixing assisted by quantum coherence in tunnel-ionized CO molecules. The electronic is created when pump pulses resonantly excite transitions + . technique allows for selective switch provided ...

Abstract This study investigated the feature importance of near-infrared spectra from random forest regression models constructed to predict carbonization characteristics hydrochars produced by hydrothermal kraft lignin. The model achieved high coefficients determination 0.989, 0.988, and 0.985 with root mean square errors 0.254, 0.003, 0.008 when predicting carbon content, atomic O/C ratio, H/...

Wavelength-selective nanoantenna emitters have attracted considerable attention due to their widespread applications ranging from thermal radiation management thermophotovoltaics. In this paper, we design a wavelength-selective emitter based on the excitation of gap-surface plasmon modes using metal–insulator–metal configuration (silicon dioxide (SiO2) sandwiched between silver (Ag) layers) for...

Coded aperture snapshot spectral imaging (CASSI) provides a mechanism for capturing a 3D spectral cube with a single shot 2D measurement. In many applications selective spectral imaging is sought since relevant information often lies within a subset of spectral bands. Capturing and reconstructing all the spectral bands in the observed image cube, to then throw away a large portion of this data,...

A common feature of evening near-range ionospheric backscatter in the CUTLASS Iceland radar ®eld of view is two parallel, approximately L-shellaligned regions of westward ̄ow which are attributed to irregularities in the auroral eastward electrojet region of the ionosphere. These backscatter channels are separated by approximately 100±200 km in range. The orientation of the CUTLASS Iceland rada...

Objective(s): Oxytocin is involved in modulation of many brain-mediated functions. In the present study, we investigated the central effects of oxytocin and its receptor antagonist, atosiban on inflammatory pain. The contribution of opiate receptors was explored using non-selective and selective antagonists. Materials and Methods: The fourth ventricle of the brain of anesthetized rats was impla...
