ABSTRACT Nanocomposites of natural rubber (NR) and pristine clay (clay) were prepared by latex mixing, then crosslinked with phenolic resin (PhOH). For comparative study, the PhOH‐crosslinked neat NR was also prepared. Influence of clay loading (i.e., 1, 3, 5, and 10 phr) on mechanical properties and structural change…
By boosting surface roughness via devising hybrid dimensional magnetic microstructures on 3D substrates, a remote controllable, superhydrophobic/superoleophilic melamine foam (MM-RSF) was obtained, showing magnetic-driven oil sorption behavior and great potential in oil/water separation.
The aim of this study is to simultaneously improve the mechanical strength and fracture toughness properties of recycled poly(ethylene terephthalate) (r-PET). For this purpose, Joncryl ® was used as chain extender and Lotader ® was used as impact modifier. The combined effect of chain extender and impact modifier on t…
The resulting ZnO film on zeolites could effectively prevent exposing the HZSM-5 framework to steam during the reaction and regeneraton processes.
The development of Ru(II) functionalized gold nanoparticles 1–3·AuNP is described. These systems were found to be mono-disperse with a hydrodynamic radius of ca. 15 nm in water but gave rise to the formation of higher order structures in buffered solution. The interaction of 1–3·AuNP with DNA was also studied by spect…
Abstract The present research work was carried out to develop the prediction models for blended ring spun yarn evenness and tensile parameters using artificial neural networks (ANNs) and multiple linear regression (MLR). Polyester/cotton blend ratio, twist multiplier, back roller hardness and break draft ratio were us…
Hydrogel composite membranes (HCMs) are used as novel mineralization platforms for the bioinspired synthesis of CaCO3 superstructures. A comprehensive statistical analysis of the experimental results reveals quantitative relationships between crystallization conditions and crystal texture and a strong selectivity towa…
Point defects in wide bandgap semiconductors are promising candidates for future applications that necessitate quantum light sources. Recently, defect-based single photon sources have been observed in ZnO that are very bright and remain photoactive from 4.5 K to room temperature. Despite several investigations, the st…
V2AlC belongs to a family of ternary nano-laminate alloys known as the MAX phases, which exhibit a unique combination of metallic and ceramic properties. In this work V–Al–C coatings with deposited (V,Al)2C nano-crystallines and amorphous phase were magnetron sputtered from V2AlC compound target. The subsequent vacuum…
PURPOSE: Diabetic nephropathy (DN) is the leading cause of renal failure; however, current clinical tests are insufficient for assessing this disease. DN is associated with changes in renal metabolites, so we evaluated the utility of chemical exchange saturation transfer (CEST) imaging to detect changes characteristic…
Polyacrylic acid functionalized Fe3O4 nanoparticles (PAA-MNPs) of average size of 10 nm are prepared by a simple soft chemical approach. These PAA-MNPs are conjugated with folic acid through peptide bonding between the carboxylic group on the surface of PAA-MNPs and the amine group of folic acid. The good colloidal st…
A series of silver supported catalysts have been developed and proposed for mild oxidation of glycerol in the liquid phase. High selectivity to glycolic acid, stability in both continuous-flow and periodic mode of reaction, and good resistance to crude glycerol impurities have been achieved.
To explore the mechanism of graphene chemical vapor deposition (CVD) growth on a catalyst surface, a molecular dynamics (MD) simulation of carbon atom self-assembly on a Ni(111) surface based on a well-designed empirical reactive bond order potential was performed. We simulated single layer graphene with recorded size…
A facile sequential growth process is developed to synthesize uniform lanthanide-doped upconversion (UC) core–shell nanoparticles with controlled nanostructures and enhanced UC fluorescence, which provides an important tool for their extensive applications in the near future.
The electrical properties of identically fabricated PtO x Schottky contacts on -oriented gallium oxide thin films and bulk crystals were investigated using current–voltage measurements at room temperature. The homogeneous barrier height of the Schottky contacts on thin films is 1.55 ± 0.15 eV, which is significantly s…
The main topic of this paper is a focus on some non-conventional tools to preserve the microbiological and physico-chemical quality of fresh-cut fruits and vegetables. The quality of fresh-cut foods is the result of a complex equilibrium involving surface microbiota, storage temperature, gas in the headspace and the u…
AIMS: Here we report a one-step approach for reproducible synthesis of finely tuned targeting multifunctional hybrid nanoparticles (HNPs). MATERIALS & METHODS: A microfluidic-assisted method was employed for controlled nanoprecipitation of bisphosphonate-conjugated poly(D,L-lactide-co-glycolide) chains, while coencaps…
The properties of any material are fundamentally determined by its electronic band structure. Each band represents a series of allowed states inside a material, relating electron energy and momentum. The occupied bands, that is, the filled electron states below the Fermi level, can be routinely measured. However, it i…
The world-wide production of carbon nanotubes (CNTs) has increased substantially in the last decade, leading to occupational exposures. There is a paucity of exposure data of workers involved in the commercial production of CNTs. The goals of this study were to assess personal exposure to multi-walled carbon nanotubes…
Abstract Durch äußere Stimuli ausgelöste Strukturumwandlungen spielen bei vielen biologischen Vorgängen eine wichtige Rolle, oft als Teil kinetisch gesteuerter Szenarien. Licht hat sich bei supramolekularen Nachbildungen solcher Systeme als perfekter externer Trigger erwiesen. Hier berichten wir über die lichtgesteuer…
