In this study, ZnTe crystal was applied to provide precise thermal sensing for cryogenic temperatures. Multiple techniques, namely Raman and photoluminescence spectroscopies, were used broaden the operating temperature range improve reliability of proposed thermometers. Raman-based could be in 20-100 K, while luminescence-based thermometry utilized a narrower 20-70 K. However, latter strategy provides better relative sensitivity resolution. The best performances based on single...
Film-based cellulose nitrate negatives are a unique class of objects that contain important information about life, historical buildings, and the natural landscapes past years. Increased sensitivity to storage conditions makes these highly flammable can lead irretrievable loss. In this regard, timely identification degradation process is necessary step towards further conservation restoration. This work studies possibility detecting based on artifact yellowing. A total 20 normal yellowed...
Deep eutectic solvents (DES) have emerged as versatile, sustainable media for the synthesis of nanomaterials due to their low toxicity, tunability, and biocompatibility. This study develops a one-step method modify commercially available screen-printed electrodes (SPE) using laser-induced pyrolysis DES, consisting choline chloride tartaric acid with dissolved nickel acetate dispersed graphene. The were patterned 532 nm continuous-wave laser in situ formation Ni nanoparticles decorated on...
In this work, we investigated individual bacteria M. tuberculosis belonging to strains of the Beijing family with different drug sensitivity (sensitive, multi and extensive drug-resistant) by surface-enhanced Raman spectroscopy (SERS) in fingerprint region. The latter is focused on spectral bands, which correspond a set glutathione bands DNA methylation patterns revealed due 5-methylcytosine biomarkers. It shown that these features can be correlated methylation. Thus, since kind diagnostics...
ABSTRACT The inherent benefits of Raman spectroscopy make it a suitable tool for the analysis complex biological objects. Detection and imaging mammalian cells is one its development areas. Plasmonic tags endowed with alkyne reporter intended bioimaging by surface‐enhanced scattering in silent region are presented. Gold nanorods covalently conjugated 4‐aminotolane were obtained using dithiobis (succinimidyl propionate) characterized UV–Vis absorbance, transmission electron microscopy,...
This paper discusses the applicability of optical and vibrational spectroscopies for identification characterization T-2 mycotoxin. Vibrational states electronic structure toxin molecules are simulated using a density-functional quantum-mechanical approach. A numerical experiment aimed at comparing predicted structural, properties with analogous characteristics structurally similar 3-deacetylcalonectrin is performed, characteristic spectral features that can be used as fingerprints...
Solid solutions Rb0.95NbxMo2-xO6.475-0.5x (x = 1.31-1.625) having a β-pyrochlore structure with an orthorhombic system were synthesized by solid-state reaction. The elemental composition was confirmed X-ray microanalysis. Rb0.95Nb1.375Mo0.625O5.79 refinement performed using the Rietveld method. crystal consists of ordered O-Mo-O chains partly occupied Nb atoms. oxygen vacancies are necessary to save electroneutrality unit cell. It predominantly appears between Mo atoms that lead form two...
Wheat has played an important role in human agriculture since ancient times. Increasing rates of processed wheat product fabrication require more and laboratory studies quality. This, turn, requires the use, production field conditions, sufficiently accurate, fast relatively low-cost quality control methods, including detection fungal diseases. One most widespread diseases world is ergot caused by fungi genus Claviceps. Optical methods are promising for this disease identification due to...
The conversion of metal-organic frameworks (MOFs) into advanced functional materials offers a promising route for producing unique nanomaterials. MOF-derived systems have the potential to overcome drawbacks MOFs, such as low electrical conductivity and poor structural stability, which hindered their real-world applications in certain cases. In this study, laser scribing was used pyrolysis Cu-based MOF ([Cu4{1,4-C6H4(COO)2}3(4,4'-bipy)2]n) synthesize Cu-CuO@C composite on surface...
At present, one of the critical problems in agriculture is identification cereals, including oats, infected by Fusarium spp. genus fungi. Timely diagnostics can prevent further disease spread and help to identify already stored grains. In this regard, aim work develop spectroscopic approaches that determine As an object investigation “Zalp” cultivar oat, both healthy grains 2020 harvest were chosen. The included FTIR mid-IR region, Raman, luminescence methods. Combination chemometric tools...
Anhydrofusarubin is a naphthoquinone pigment synthesized by number of Fusarium genus fungi. Being biologically active substance, it demonstrates promising antibiotic properties and rather good hypothetical effectiveness against certain types cancer. In this regard, an important task arises to study the structural spectral manifestation in order identify characterize substance terms synthesis application purposes. aim article was structure molecule its structure-property correlation. The...
Photographic artifacts carry important historical and cultural information. Materials used in photography at the turn of XIXth XXth centuries tend to degrade both over time if temperature humidity conditions storage are violated. In this connection, question arises determining safety degree monitoring condition photographic materials. Close attention should be paid materials that become flammable as a result decomposition. This class objects includes films based on cellulose nitrate. study...

New organic–inorganic hybrids have been synthesized by the intercalation of n-alkylamines (methylamine, ethylamine, n-propylamine, n-butylamine, n-hexylamine, and n-octylamine) into structure protonated hydrated form perovskite-like layered titanate H2K0.5Bi2.5Ti4O13·H2O (HKBT4·H2O). The possibility synthesis hybrid materials was studied in a wide range conditions. It found that interlayer water plays crucial role formation intercalated hybrids. obtained compounds were characterized with...
