In this study, microcrystalline cellulose (MCC) was isolated from walnut and apricot shells (WS AS) as agricultural wastes in order to use it reinforcement polymer composites. The extracted by alkaline treatment bleached peroxide an environmentally friendly treatment, called (WC) (AC). chemical composition of the samples set according Technical Association Pulp Paper Industry (TAPP). After trea...

Abstract To our knowledge, there are few studies on the association between carbohydrate molecular structure spectral profiles of barley grain and ruminant-relevant nutritional characteristics. This study aimed to associate processing-induced changes in with profiles. The heat processing methods included: dry roasting, autoclaving, microwave irradiation. were determined which included chemical ...

Abstract Infrared spectroscopy allows to reliably distinguish between calcites formed by different processes, e.g. geogenic and anthropogenic calcite. This approach can be used for rapid sample analysis in the radiocarbon dating of mortars. The datable component is represented calcite, that results from reaction calcium hydroxide with atmospheric CO 2 during hardening material. However, possibl...

To assess the possibility of terahertz technology for the determination of drug concentration in blood, we endeavored to apply a terahertz (THz) attenuated total reflection (ATR) method to measure the levels of theophylline in saline. A change in reflected THz wave amplitude was observed in a theophylline concentration-dependent manner. This result was obtained with simple measurements of compa...

In a recent work (J. Phys. Chem. C 2016, 120, 3350-3359), we have introduced the concept of surface-enhanced, two-dimensional attenuated total reflectance (2D ATR IR) spectroscopy with modest enhancement factors (<50) using small plasmonic noble metal nanoparticles at solid-liquid interfaces. Here, we show that employment of almost continuous noble metal layers results in significantly stronger...

The influence of shear flow of solvent past poly(methyl methacrylate) chains adsorbed onto germanium oxide from dilute carbon tetrachloride solution (a near-θ solvent) was studied at shear rates from 0 to 4 × 104 s-1 with the new apparatus described in this paper. Both the adsorbed amount and the flow-induced surface orientation (surface dichroism) were measured. The method involved measurement...
