INTRODUCTION: A practical, inexpensive and reliable method is needed for assessment of volume status in hemodialysis (HD) patients. In this study the effi ciency of bioimpedance spectroscopy (BIS) for detection of hyperv...

Surface-enhanced Raman spectroscopy (SERS) has been widely investigated and employed as a powerful optical analytical technique providing fingerprint vibrational information of molecules with high sensitivity and resolu...

IntroductionAlzheimer’s disease (AD) is strongly associated with cerebrovascular dysfunction and impaired glymphatic clearance. These dysfunctions may precede, contribute to, and interact bidirectionally with AD pathol...

Cu2ZnSnS4 (CZTS) is one of the promising materials for absorber layers of new-generation thin film solar cells. Various synthetic routes of materials preparation and structural characterization have been explored so far....

Abstract The objective of this study was to explore the potential of front face fluorescence spectroscopy (FFFS) as rapid, non-destructive and inclusive technique along with multi-variate analysis for predicting meat adu...

IntroductionMalodors in the human body can diminish comfort in living and working environments, potentially increasing stress and dissatisfaction levels. Therefore, there is a growing need to objectively characterize the...

The ancient records about herbal medicine show traditional healing practices are deeply rooted in Indonesian culture. The medical use of plants decreased because of inheritance customs combined with the lack of written d...

Sensing the scattered fields of single metallic nanostructures is a crucial step towards the applications of isolated plasmonic antennas, such as for the sensing of single molecules or nanoparticles. In the past, both ne...

Abstract This manuscript presents the feasibility of designing a digital Lock-In Amplifier (LIA) for measuring experimental sys-tems through optical measurement techniques, from 32-bit micro-controller platforms, derived...

Scattering-type scanning near-field optical microscopy (s-SNOM) and Fourier transform infrared nanospectroscopy (nano-FTIR) are emerging tools for physical and chemical nanocharacterization of organic and inorganic compo...

In this study, the conformational behavior of N-benzyl-N-(furan-2-ylmethyl) acetamide in chloroform was addressed by using a combined experimental/theoretical strategy using NMR spectroscopy and quantum chemical calculat...

Spectroscopy of shallow donors is a tool to test theoretical models and to reveal properties of semiconductors. In this work we consider intra-shallow impurity transitions by studying a CdTe/(Cd, Mg)Te structure grown by...

Dental caries requires remineralizing agents to restore the dentin. Mauli banana stem gel is predicted to be an alternative material for mineral deposition during the remineralization process. Fourier transform infrared ...

The Hualfin Valley presents a long occupation period from the first agropastoralist societies (BC 200) to the Inka occupation (AD 1400). Ceramic production has played a fundamental role, being an important indicator of s...

This study investigates size-controlled, quantum-confined CdSe/ZnS core–shell quantum dots using core-hole clock spectroscopy in combination with post-collision interaction (PCI) line shape analysis, providing insights...

In this work, a quantitative analysis of heavy metals Cr and Cu in fluvial sediments was carried out by Laser-induced breakdown Spectroscopy (LIBS) to assess the anthropogenic. To perform the analysis, different sediment...

Copper metal nanoparticles (Nps) have received increasing interest during the last years due to their potential applications in several fields of science and technology. Their optical properties depend on the characteris...

Abstract Antlers are the fastest-growing osseous tissue in mammals, undergoing periodic regeneration associated with the mating season. Their high strength and resistance to fracture have made them a valuable material fo...

Background Lupus nephritis (LN) is a leading cause of mortality in patients with systemic lupus erythematosus (SLE), and the accurate classification of renal pathological subtypes is crucial for reducing mortality rates ...

The microhydration of rock salt (NaCl) molecules was investigated theoretically by density‐functional theory and force field calculations and experimentally by high‐resolution Penning ionization electron spectroscopy...

The widely distributed pollutant tributyltin (TBT) was analyzed in different environmental samples (waters and sediments) combining preconcentration on a nylon membrane, excitation–emission fluorescence matrices direct...

The resonant Raman spectra of the H2O⋯Cl2 and H2O⋯Br2 halogen-bonded complexes have been studied in the framework of a 2-dimensional model previously used in the simulation of their UV-visible absorption spectra usin...

In this work granular activated carbon has been chosen as an absorbent in order to investigate theCr(VI) reduced by adsorption experiments. Several batch chromium-sorption experiments were carried out using 0.25 gof gran...
