Nitrogen-doped carbon dots synthesized from citric acid as a precursor have recently been considered to contain fluorescent derivatives of citrazinic acid, which contribute their emission in the blue spectral range. To study impact such molecular species on optical properties dots, we three samples employing and different nitrogen sources: ethylenediamine, hexamethylenetetramine, triethanolamine. On basis analysis content its coordination by X-ray photoelectron spectroscopy, FTIR spectra,...
Abstract Impedimetric affinity biosensors are, without any doubt, among the most sensitive analytical devices available, offering low limits of detection and wide linear response ranges. There however, only a few papers detailing application impedimetric for analysis clinically relevant samples with due clinical performance. The fact that these have not found their way to commercial or use date might be surprising, since an electrochemical assay platform based on portable potentiostats is...
Recently, molecular fluorophores were shown to be formed in the bottom-up chemical synthesis, contributing emission of carbon dots (CDs), derived from a citric acid precursor. We applied an ammonothermal synthesis toward CDs, employing two reactants and supercritical ammonia functioning as both solvent The resulting nanoparticles are identified amorphous aggregates based on citrazinic derivatives, which resemble many features typically reported characteristic for CDs. absorb emit at short...
Carbon Dots (CDs), fabricated by hydrothermal bottom-up synthesis, are complex materials, whose optical properties influenced multiple factors. The presence of domains conjugated sp2 carbon, which formed upon carbonization precursors at high temperature; nitrogen doping; and as recently shown, the molecular fluorophores, contributing to emission such CDs. We conducted a series syntheses, each designed with specific reaction conditions that reveal contribution above-mentioned Specifically, we...
Two-dimensional layered nanomaterial Ti3C2TX (a member of the MXene family) was used to immobilise enzyme sarcosine oxidase fabricate a nanostructured biosensor. The device applied for detection sarcosine, potential prostate cancer biomarker, in urine first time. morphology and structures have been characterised by atomic force microscopy (AFM) scanning electron (SEM). Electrochemical measurements, SEM AFM analysis revealed that interfaced with chitosan is an excellent support immobilisation...
Abstract Boron is an essential micronutrient that has raised much interest, given the narrow balance between its necessity and toxicity. Both natural anthropogenic emissions of boron into water sources can eventually deteriorate quality endanger ecosystem. In this review, we first present a general outline importance boron, chemistry in water, contamination, consequences followed by recent progress removal methods based on adsorption. The adsorbents for deboronation generally be classified...
Hydrogen (H2) is increasingly recognized as a key player in the journey towards carbon neutrality, with ammonia (NH3) and formic acid (FA) emerging significant hydrogen vectors. This review highlights advancements catalyst efficiency for FA synthesis from CO2, particularly bismuth (Bi) tin (Sn) catalysts. It investigates diverse NH3 production methodologies, such electrochemical, thermochemical, photochemical processes, underscores integration of renewables to address their energy demands....
