Green synthesis, characterization and functional validation of bio-transformed selenium nanoparticles

Selenium, an essential micronutrient with potent anticancer and antioxidant properties, the inorganic form of selenium is highly toxic, while organic and elemental nanoforms are more bioavailable and less toxic and have gained attention owi...

Dielectric Properties of Phosphatidylcholine Membranes and the Effect of Sugars

Simple carbohydrates are associated with the enhanced risk of cardiovascular disease and adverse changes in lipoproteins in the organism. Conversely, sugars are known to exert a stabilizing effect on biological membranes, and this effect is...

Investigating the performance of the fluorescent sensor g-C3N4/Fe/Cu in detecting the Tenofovir drug

Abstract Tenofovir is an antiviral drug that prevents the replication of AIDS and hepatitis B viruses. To minimize the harmful side effects of the drug on the body, it is essential to determine its precise concentration in the blood. Fluore...

Synthesis and properties of fluorene based small molecule acceptors containing aromatic malononitrile functionalities

Four novel small molecule acceptors (SMA) with fluorene-based cores were synthesized with terminal phenyl, thienyl, and furyl malononitrile groups in good yields. The products were obtained from a two-step reaction of 2,2′-(9,9-dioctyl-9H-f...

Transient measurement of phononic states with covariance-based stochastic spectroscopy

Volcanic Pozzolan from the Phlegraean Fields in the Structural Mortars of the Roman Temple of Nora (Sardinia)

In this paper, we discuss the presence of volcanic pozzolans in the structural mortars of the Roman Temple of Nora in Sardinia (3rd c. AD), represented by pyroclastic rocks (pumices and tuffs) employed as coarse and fine aggregates. The pro...

Computational analysis of visible frequency plasmonic properties of graphene on wide band gap heterostructures

Abstract Control over plasmonic properties and local electric field enhancement has become an essential aspect of many modern technologies. Here we investigate these phenomena in graphene / hexagonal boron nitride (G/h-BN) heterostructures ...

Phosphopeptide binding to the N-SH2 domain of tyrosine phosphatase SHP2 correlates with the unzipping of its central β-sheet

SHP2 is a tyrosine phosphatase that plays a regulatory role in multiple intracellular signaling cascades and is known to be oncogenic in certain contexts. In the absence of effectors, SHP2 adopts an autoinhibited conformation with its N-SH2...

Correlating single-molecule rupture mechanics with cell population adhesion by yeast display

Here, we present a method based on yeast surface display that allows for direct comparison between population-level cell adhesion strength and single-molecule receptor-ligand rupture mechanics. We developed a high-throughput yeast adhesion ...

Controlled Plasmonic Coupling in Silver Nanoplate Dimers for Enhanced Plasmonic Sensing

Noble metal nanostructures provide versatile platforms for light manipulation through localized surface plasmon resonances (LSPRs). Among them, triangular silver nanoplates (AgNPTs) exhibit strong field-enhancement and spectral tunability, ...

Mechanism analysis of mechanical extraction of Pleioblastus amarus fibers by saturated steam pretreatment

Abstract Currently, bamboo fibers (BFs) are commonly processed through alkali boiling softening pretreatment, which generates wastewater that poses environmental pollution risks. This process is also complex and requires significant human a...

From mid-infrared luminescence to laser gain in chalcogenide glasses and glass-ceramics

Mid-infrared (MIR) lasers operating in the 2–6[Formula: see text][Formula: see text]m region are important for spectroscopy, sensing, communications, medicine, lidar, and electro-optical applications. Chalcogenide glasses and glass–ceramics...

Measurement of the Filling Degree and Droplet Size of Individual Double Emulsion Droplets Using Raman Technologies

Double emulsions arouse great interest in various industries due to their ability to encapsulate value-adding ingredients. However, they tend to be unstable due to their complex structure. Several measurement techniques have already been de...

Application of the linear method of discriminant analysis of reflectance spectra in the near infrared region for the species identification of fish of the Salmonidae family

It is well known that fish belonging to the Salmonidae family differ in their nutritional value. Anatomical and morphological features of different salmon species have a certain similarity; therefore, representatives of this family are most...
