The practice of the zircon typomorphism studies using IR microscopy as applied to forecasting and prospecting for base and precious metals deposits

open access: yesРуды и металлы
A potential effectiveness of IR microscopy in application to forecasting and prospecting for base and precious metals deposits is demonstrated on examples of studying zircon crystals collected at the Mechiveem area (Okhotsk-Chukotka volcanoplutonic belt),

Ab Initio Simulation of the IR Spectrum of Hydrated Kaolinite

open access: yesCrystals, 2021
The hydration of the basal surfaces of kaolinite is studied by theoretical methods. The cluster method was used to simulate the positions of atoms. The positions of the atoms of the basal surfaces of dry and hydrated minerals are optimized by minimizing ...

Effect of Calendering and Surface Treatment on the Thermochromic Response of Cholesteric Liquid Crystals on PET Nonwovens

open access: yesAdvanced Engineering Materials, EarlyView.
This study explores the influences of calendering and surface treatment during direct ink writing (DIW) of thermochromic cholesteric liquid crystal (CLC) on PET nonwovens. For the PVA‐coated nonwovens, calendering reduces pore size leading to reduced ink absorption and enhanced spreading. The NeverWet‐coated nonwovens improve thermochromic responses by

The Radiance Differences between Wavelength and Wavenumber Spaces in Convolving Hyperspectral Infrared Sounder Spectrum to Broadband for Intercomparison

open access: yesRemote Sensing, 2019
Converting the hyperspectral infrared (IR) sounder radiance spectrum to broadband is a common approach for intercomparison/calibration. Usually the convolution is performed in wavenumber space.

Laser‐Induced Graphene from Waste Almond Shells

open access: yesAdvanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

The Post-outburst Spectrum of L1415-IRS

open access: yesResearch Notes of the AAS
Abstract We present near-infrared spectroscopic observations of L1415-IRS, a Class I type young stellar object (YSO) that underwent a factor of >30 photometric outburst in the early 2000s. Ours is the first reported spectroscopy of this deeply embedded source. Both components of L1415-IRS present continuum plus

Some empirical correlations between the thermodynamic properties of hydrogen cyanide, water and acetylene molecules and their infrared spectra [PDF]

open access: yesTrakia Journal of Sciences, 2018
A new method for calculating vibrational modes in the infrared region of the spectrum is proposed. The method is based on the thermodynamic parameters of the molecules- standard molar Gibbs free energy change of molecular formation ΔGf0 (kJ/mol ...
