This article focused on 3,5-dimethyl-4-nitropyrazole (C5H7N3O2) as the subject of research for hydrogen-bonded energetic materials. It examined the characteristics and properties of this organic crystal under high pressure using a diamond anvil cell (DAC) and Raman spectroscopy. High-pressure Raman spectroscopy studies indicate that 3,5-dimethyl-4-...

We have investigated two Nueva Cádiz tubular glass beads (16th-Century) from the indigenous localities of the Tamtoc Peninsula, Huasteca Potosina (Mexico). It was part of an exceptional discovery of 96 European glass beads found in archaeological contexts of the Early Colonial period (dated 14C 1512 AD ± 30 years, before 1560 AD). They correspond t...

Osteosarcoma (OS) is the most common malignant primary bone tumor in humans and occurs in various subtypes. Tumor formation happens through malignant osteoblasts producing immature bone. In the present paper we studied two different subtypes of osteosarcoma, from one individual with conventional OS with massive sclerosis and one individual with par...

We compared the impact of alumina doping on the structure of Al2O3–SiO2 amorphous thin films and bulk glasses using Raman spectroscopy and x‐ray diffraction. In both thin films and bulk glasses, the addition of Al2O3 is accompanied by an increase in the mean Si–O–T angle and an evolution of the ring statistics with a decrease in the proportion of s...

Na-ion batteries (NIBs) with ionic liquid (IL) electrolytes are promising candidates for large-scale energy storage devices owing to the abundance of Na resources and the safety of ILs. In our previous study, we have demonstrated the improved rate capability of NIBs consisting of a hard carbon negative electrode, an NaCrO₂ positive electrode, and a...

We introduce a new application for online Raman spectroscopy to monitor adsorption breakthrough curves of aglucose and xylose mixtures. Univariate and multivariate Partial Least Squares (PLS) calibration models aredeveloped for each sugar when they are dissolved in water and in the case of the ethanol addition as a cosolvent.The models are validate...

With approximately 1 in 20 individuals experiencing tooth fractures annually, there is a pressing demand for dental restorations. However, commercially available dental restoration options force consumers to compromise between aesthetics and mechanical properties. Highly esthetic cubic yttria-stabilized zirconia (YSZ) deviates from the popularity o...

Surface-enhanced Raman spectroscopy (SERS) is a powerful optical sensing technique used in various applications, including medicine, microbiology, and environmental analysis. Planar SERS substrates are of particular interest due to their ease of integration in lab-on-chips and better reproducibility compared to colloidal SERS. The performance of th...

Here we study the Raman spectra of Barium Titanate, BaTiO3, given in the RRUFF and ROD databases. Being the Raman bands strongly asymmetric, we are deconvoluting them by means of the q-BWF functions. These functions are generalizing the Breit-Wigner-Fano line shape in the framework of the q-exponential function of Tsallis statistics. Besides the de...
