Microalgae are exceptional organisms from a nutritional perspective, boasting an array of bioactive compounds that have long justified their incorporation into human diets. In this study, we explored the potential five microalgae species: Nannochloropsis sp., Tetraselmis chuii, Chaetoceros muelleri, Thalassiosira weissflogii, and Tisochrysis lutea. We conducted comprehensive analyses profiles, encompassing protein content, individual amino acid composition, mineral trace element levels,...
AbstractAbstractChemical vapor generation (CVG) offers several significant advantages for analyses, including efficient matrix separation, which often leads to a reduction of interferences and better detection limits; high transport efficiency analyte into the atomic spectroscopic detector; in some cases, selectivity permit differentiation chemical species particular element enable use gas-phase separation methods speciation elements.The development CVG techniques from Marsh test (arsine...
Bioengineered spider silk is a biomaterial that has exquisite mechanical properties, biocompatibility, and biodegradability. Iron oxide nanoparticles can be applied for the detection analysis of biomolecules, target drug delivery, as MRI contrast agents therapeutic hyperthermia-based cancer treatments. In this study, we investigated three bioengineered silks, MS1, MS2 EMS2, their potential to form composite material with magnetic iron (IONPs). The presence IONPs did not impede self-assembly...
The growing human population renders challenges for the future supply of food products with high nutritional value. Here, we enhanced functional and value biscuits, a popular sweet snack, by replacing wheat flour 2%, 6%, or 10% (w/w) cricket powder. Consumer acceptance ratings reference 2% augmented cookies were comparable, whereas higher levels enhancement received inferior consumer scores. This relatively small change in biscuit recipe provided significant nutritionally desirable...
The growing interest in chemical and photochemical generation techniques results from a number of advantages for analysis, including high transport efficiency the analyte into atomization/excitation/ionization sources efficient matrix separation, often leading to reduction interference improvement limits detection.
The analytical potential of a coupled continuous-microflow ultrasonic nebulizer triple-mode micro capillary system (μ-USN/TCS)-Ar/He mixed gas microwave induced plasma-optical emission spectrometry (MIP-OES) has been evaluated for the purpose determination metal volatile species (Au, Ag, Pd, Pt, Rh). An extremely short reaction time between sample, acid and reductant rapid separation products is obtained by mixing sodium borohydride solution at quartz oscillator, converting liquids into...
To counterbalance the growing human population and its increasing demands from ecosystem, impacts on it, new strategies are needed. Use of organic fertilizers boosted agricultural production, but further increased ecological burden posed by this indispensable activity. One possible solution to conundrum is development application more environmentally neutral biofertilizers. The aim study was compare effectiveness two doses Hermetia illucens frass (HI frass) with commercial cattle manure in...
Threats connected with contamination of environment heavy metals include negative influence on human and animal health also negatively the biodiversity ecosystems. While applying various techniques metal remediation from soils, an important problem is adsorption ions solid particles. In this respect, composition properties soil strongly affect efficiency process. Therefore, aim study was to determine copper(II) zinc(II) leaching soils different types (luvisols, podzols, chernozem) by means...
Agriculture is faced with the need to reduce mineral fertilizers in order costs but also meet political goals. Resilience-enhancing climate change, especially face of increasingly frequent and prolonged droughts, has become another issue. The dynamically increasing production insects for feed food purposes one answers this challenge. This study assesses fertilizing efficacy effect frass derived from Black Soldier Fly (Hermetia illucens) on lettuce (Lactuca L.) growth, including aspects such...
ABSTRACT The commercial ultrasonic nebulizer NOVA-DUO (Optolab, Warsaw, Poland) has been evaluated for the simultaneous determination of transition (Au, Ag, Cd, Cu, Mn, Ni, Pb, Zn) and noble (Pd, Pt, Rh) volatile metal species by microwave induced plasma–optical emission spectrometry (MIP-OES). Simultaneous mixing nebulization two solutions (acidified sample reductant) on piezoelectric transducer, with possibility flow rate adjustment, permits a wide variation sensitivity. vapor-phase were...
ABSTRACT A novel synergic effect of ultrasonic nebulization (USN) and ultraviolet (UV) radiation (photolysis) when used in combination has been exploited for efficient generation conventional hydride elements (As, Bi, Sb, Se, Sn), Hg vapor, volatile molecular Cd species. Several UV-based systems were studied, the most advantageous design being an nebulizer fitted with a 6 W mercury pen lamp supplying microliter sample to quartz oscillator, converting liquid into aerosol at entrance UV spray...
Three different micronebulizers, the micro3 (M3), flow focusing pneumatic nebulizer (FFPN) and microcapillary array (NAR-1), were compared with a conventional Meinhard concentric (PN) working at low liquid rates for elemental analysis of samples by microwave induced plasma optical emission spectrometry (MIP-OES). nebulizers (M3, FFPN, PN) operated in conjunction same cyclonic spray chamber.
