Finite element modeling (FEM), microscopy, X-ray computed tomography (CT) and mechanical property tests were used to study the microstructure, porosity properties of an AlSi10Mg alloy produced by selective laser melting (SLM). The simulation melt pool thermal history under different energy densities optimized result with density 44.5 J·mm−3. high cooling rate during SLM process significantly refined previous α-Al dendrites. growth direction network-like Al-Si eutectic structure at...
Bisphenol S (BPS) and bisphenol F (BPF) are increasingly used in manufacturing consumer products to replace the use of A (BPA), but exposure data limited, particularly among pregnant women. Here, we measured BPA, BPS, BPF levels urine samples, collected from 941 women over three trimesters. We examined correlations, coexposure patterns, variability, predictors bisphenols using Spearman's correlation coefficient, percentile analysis, intraclass linear mixed models, respectively. assessed...
Silk has poor antibacterial and UV protection properties which limit its application fields. Silver nanoparticles (AgNPs) have attracted great attention due to their excellent activity. This work proposed a green efficient way prepare AgNPs from silver nitrate using the aqueous extract tea stem waste, functional finishing of silk material with resulting by an immersion technique. prepared at pH 9 40 ℃ exhibited ultra-fine particle size (<20 nm), good dispersibility storage stability. When...
Grape skins and seeds rich in polyphenolic compounds are low-value byproducts from the wine-making. The valorization of such is great significance. This work presented a novel application grape seed proanthocyanidins (GSPs) dyeing flame-retardant antibacterial treatment silk. study on adsorption isotherms revealed that multiple interactions occurred between GSPs silk, including electrovalent bonding, hydrogen van der Waals forces. color depth silk mainly depended temperature GSP...
Uncovering the molecular changes at site where Aβ is deposited plays a critical role in advancing diagnosis and treatment of Alzheimer's disease. However, there currently lack suitable label-free imaging method with high spatial resolution for brain tissue analysis. In this study, we propose modified desorption electrospray ionization (DESI) mass spectrometry (MSI) method, called segmented temperature-controlled DESI (STC-DESI), to achieve high-resolution high-sensitivity metabolomics...
Rationale Bisphenols, such as bisphenol A (BPA) and S (BPS), are widely used in industrial products, although they have been demonstrated to be environmental contaminants with toxicity. However, few studies on the mass spectrometric fragmentation pathway of these compounds reported using high-resolution spectrometry (HRMS). Methods The MS/MS fragmentations nine bisphenols, together several corresponding isotope-labeled compounds, were studied by Orbitrap MS electrospray ionization (ESI)...
Natural bioactive compounds have received increasing attention in the functional modification of textiles. In this work, tannic acid was used to impart antibacterial and antioxidant functions silk using an adsorption technique, properties on were studied. The quantity increased with decreasing pH range 3-7. rates uptake by well correlated pseudo-second-order kinetic model, calculated activation energy 93.49 kJ/mol. equilibrium isotherms followed Langmuir model. rate isotherm studies...
A copper-catalyzed aerobic oxidative C-C single bond cleavage of acyclic unstrained oxime acetates is reported, providing various aryl nitriles and ketones in good yields. Mechanistic studies indicate a radical procedure involved this transformation, the oxygen atom ketone products originated from O2 air. Oxime as an internal oxidant have been proved to be initiator, which may promote discovery novel protocol for dioxygen activation.
Recently, there is a growing trend towards the fabrication of bioactive materials by using natural extracts, which can achieve diverse functionalities and environmental benefits simultaneously. This study presents facile approach preparation UV protective silk extract from red radish (an edible root vegetable). The adsorption mechanism on was studied. results showed that displayed higher exhaustion rate at lower pH. equilibrium indicated Langmuir Freundlich isotherms were suitable to...
We report evidence for fluorescence resonance energy transfer (FRET) of gas-phase ions under ultra high vacuum conditions (10−9 mbar) inside a mass spectrometer as well ambient an electrospray plume. Two different FRET pairs based on carboxyrhodamine 6G (donor) and ATTO590 or Bodipy TR (acceptor) dyes were examined their optical properties studied. Our measurements indicate behavior the two pairs, which can be attributed to conformations in gas phase. Upon desolvation via ionization, one...
Cotton has the shortcomings of having no antibacterial, antioxidant and ultraviolet (UV) protection properties, which are great importance for health purposes. In present study, grape seed extract (GSE) mainly composed proanthocyanins (tannins) was employed to simultaneously import pale colors three aforementioned functions cotton fabric. The tests on application conditions GSE showed that pH concentration had impact color depth fabric, hue dyed fabric could be controlled in absence...
Cholesterol is a critical molecule whose dysregulation in certain brain regions related to multiple neurological disorders. It of pathological importance map the distribution cholesterol brain. Matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) has been widely used molecular imaging metabolites at high spatial resolution. However, it challenging analyze by MALDI-MS due its difficulty ionization. Herein, we present for first time type reactive matrix cholesterol....
