The particle size distribution film solutions and Fourier-transform infrared spectroscopy, X-ray diffraction, photoelectron spectroscopy films indicated that there were hydrogen bonds coordinate between SPI nano-SiO2. Scanning electron microscopy images an appropriate increase in nano-SiO2 content improved morphology Finally, effect SPI-based nanocomposite on preservation Flammulina velutipes at 4...

A cascade oxidation/Pictet–Spengler condensation/annulation process has been developed for the one-pot total synthesis of nitramarine, nitraridine, and their analogues. The procedure proceeded with easily available quinolines tryptophan derivatives. simple metal-free approach, wide substrate scope, functional group tolerance make it applicable diverse bioactive Furthermore, bioactivity evaluation identified two promising leading compounds 5d 5e potent antitumor proliferative activity against...

Abstract Compared with conventional intensity imaging, 3D and full Stokes polarization imaging can obtain higher‐dimensional information about the objects. Here, a simultaneous method using an all‐dielectric metalens network (ADMN) has been proposed experimentally demonstrated. The ADMN is composed of three sub‐metalenses simultaneously working for 0°/90°, 45°/135° linear (LP), left/right‐handed circular (L/RCP), respectively, from which images be obtained. Simultaneously, object constructed...

Abstract The development of bionanocomposite materials for packages has received increasing attention due to environmental pollution issues. However, storage results in many undesirable properties films. This study evaluated the effects on simple layer and bilayer soy protein isolate/nano‐silica (SPI/nano‐SiO 2 ) films, which may reduce migration nanoparticles, (mechanical, barrier, optical) parameters (moisture content, sulfhydryl glycerol rate) Compared SPI SPI/nano‐SiO films had a higher...

Surface morphology, electrical mechanical properties analysed. analysis result before could be regarded a reference condition to achieve high

Abstract Antimicrobial films were prepared by incorporating nano-titanium dioxide (TiO 2 ) modified silane into soy protein isolate (SPI) films. The effects of different concentrations nano-TiO 2- NM) on the physical properties, antimicrobial and microstructure SPI-based investigated. Attenuated total reflectance Fourier-transform infrared spectroscopy indicated that interaction between SPI TiO -NM was via hydrogen bonds. Scanning electron microscopy atomic force both showed with compact....

Rationale Hypercholesterolemia is an important risk factor for cardiovascular diseases and death. This study performed pseudo‐targeted lipidomics to identify differentially expressed plasma lipids in hypercholesterolemia, provide a scientific basis the diagnosis pathogenesis of hypercholesterolemia. Methods Pseudo‐targeted lipidomic analyses from 20 patients with hypercholesterolemia normal control subjects were using liquid chromatography–mass spectrometry. Differentially identified by...

Poly(N-isopropylacrylamide) (PNIPAM) microgels with a unique thermosensitive swelling and deswelling behavior in water may be capable of sensing the frictional heat sliding interfaces altering performance water-lubricated contacts accordingly. However, rheological properties PNIPAM formation mechanism tribofilms at interface during friction are currently unclear. In present study, variation behaviors kinetic characteristics phase transformation was investigated using temperature-controlled...

Recently, increasing interest to improve food safety and extend their shelf-life has led the development testing of edible films with antimicrobial properties. The soy protein isolate (SPI) were made Nisin (N), sodium lactate (NaL), EDTA (E) optical combination (C). C film showed a significant (p<0.05) effect on three pathogens, E.coli, Salmonella Bacillus cereus, which inhibitory zone is 32mm, 33.33mm 32.33mm, respectively. addition N NaL SPI reduced its mechanical properties, that is,...

As a type of promising lubricating additive, carbon nanomaterials can realize ultralow friction with diamond-like films in water. However, the long-term dispersion stability their aqueous solution remains challenge. Herein, we found that poly(N-isopropylacrylamide) (PNIPAM) microgel, which has been extensively used nanodrug delivery, considerably improve graphene oxide and hydroxylated multiwalled nanotubes solutions, while achieving an coefficient 0.02. On basis structural...

Soy protein isolate (SPI) film is a newly developed material used for packaging. However, its application has long been quite limited due to poor mechanical property stability during storage. In our study, biological glycerol-based polyester (bio-poly glycerol: adipic acid = 1:2 (BGP I), 1:1 II), and 2:1 III); w/w) as plasticizer enhance properties. These films were evaluated tensile strength (TS), elongation at break (EB), water vapor permeability (WVP), moisture content (MC), glycerol...

In this paper, the flame pyrolysis method to synthesize self-oriented carbon nanotubes (CNTs) with Fe/Mo/Al2O3 as catalyst is studied. The outcome arrays are well aligned and relatively good in morphology. Furthermore, after electric field being applied synthesis, become straighter longer significantly, higher yield.

This study reports the shear-responsive gelation of an aqueous solution polyacrylic acid-co-polyacrylamide (PAA-co-PAM). Microstructure characterization and molecular dynamics simulation reveal that shear action results in ordering polymer chains, thus increasing strength hydrogen bonds between chains forming gel. Friction tests PAA-co-PAM effectively reduces friction wear Si3N4 pairs via situ formation a colloidal lubrication film which could cooperate with silica gel layer generated on...
