Infrared nanospectroscopy of single Aβ42 oligomers and fibrils We first applied conventional bulk IR spectroscopy to investigate the chemical binding between Aβ42 fibrils formed at the end of the aggregation reaction (plateau phase, 4 h) and bexarotene (Supplementary Fig.4). However, with bulk...
Using a simple drop of serum, the mid-infrared spectrum captures a patient’s metabolic fingerprint. • A model based on mid-infrared spectroscopy provides efficient NASH screening for patients with severe obesity. Background & Aims There is an urgent medical need to develop non-invasive tests ...
Infrared spectroscopy:A powder of M(bdc)(ted)0.5 2 mg)was pressed onto a KBr pellet(~1 cm diameter,1-2 mm thick)and placed into a high pressure high temperature cell purchasedfrom Specac (product number P/N 5850c) at the focal
IR emission spectroscopya′3Σ+ -a3Π band of CSPerturbation analysisThe infrared emission spectrum of the CS a′ Σ - a Π transition has been observed with a FT spectrometer in the 1800–10,500 cm region. Thirteen bands were analyzed to obtain molecular constants in 4 (v = 0–3) ...
to increase the response, volume of EAA is maintained at low level while increasing that of sulfuric acid. Regression Table2reveals the values of regression coefficients and their associatedp-values, which are used to determine which of the effects in the model are statistically significant. It ...
The HEGS exhibits a much broader infrared absorption than common glass systems, which can be attributed to be high-frequency optical branch phonons or allowable multi-phonon processes caused by phonon broadening in the system. A broadened phonon-assisted wideband radiation (BPAWR) is induced if the...

Table 2 Main parameters of MODTRAN to be configured for Martian atmosphere Full size table Observational parameters for dust retrieval Spectral irradiance/radiance of DSR/SSR in the visible and near infrared spectral regions is to be measured with an environmental monitor camera onboard a Mars lander...
we present spectroscopic studies of Betelgeuse using high-resolution and high signal-to-noise ratio near-infrared spectra obtained at Weihai Observatory on four epochs in 2020 covering the phases of during and after dimming. We show that the dimming episode is caused by the dropping of its effecti...
Mid-infrared spectroscopy is a sensitive and selective technique for probing molecules in the gas or liquid phase. Investigating chemical reactions in bio-medical applications such as drug production is recently gaining particular interest. However, moni
