The development of the bio-nanocomposite coating materials for eggshells has received more attention because of the decline in interior egg quality. This work evaluated the effects of weight loss, Haugh unit, yolk index, air space and albumen pH, eggshell strength, number of microorganisms on eggshells, contact angle…
Incorporating aluminum is the most widely applied and industrially relevant method to functionalize amorphous silica. However, established protocols yield predominately poorly distributed and inaccessible Al species, and as a result only ∼10–15% of the present aluminum gives rise to the acid sites, hampering the overa…
The espousal of nanotechnology is a current come-up of the present revolution. As we know that the rose aphid, Macrosiphum rosae (Hemiptera: Aphididae), is a key pest on rose plant in Kashmir Valley, India, it exhibits a worldwide distribution. In the present study, we have synthesized biologically silver nanoparticle…
We present a rigorous microscopic theory of the extrinsic spin Hall effect in disordered graphene based on a nonperturbative quantum diagrammatic treatment incorporating skew scattering and anomalous (impurity-concentration-independent) quantum corrections on equal footing. The leading skew-scattering contribution to…
The oxidation behavior of NiAl(100) by molecular oxygen and water vapor under a near-ambient pressure of 0.2 Torr is monitored using ambient-pressure X-ray photoelectron spectroscopy. O 2 exposure leads to the selective oxidation of Al at temperatures ranging from 40 to 500 °C. By contrast, H 2 O exposure results in t…
The aim of our study was to investigate the effect of newly developed silver nanoparticle aqueous suspensions NanoAg1 and NanoAg2 in the mouse models mimicking ulcerative colitis and Crohn's disease. NanoAg1 and NanoAg2 were synthesized in aqueous medium with the involvement of tannic acid. To elucidate their anti-inf…
Palladium nanoparticles supported on nitrogen-doped graphene quantum dots (NGQD) were synthesized by hydrothermal coreduction of palladium salts, citric acid, and urea at 160 °C for up to 12 h. Transmission electron microscopic studies showed that in the resulting PdNGQD nanocomposites, small palladium nanoparticles c…
Self-organization of nanocomponents was mainly focused on solid nanoparticles, quantum dots, or liposomes to generate complex architectures with specific properties, but intrinsically limited or not developed enough, to mimic sophisticated structures with biological functions in cells. Here, we present a biomimetic st…
PURPOSE: To investigate the safety of gadoterate meglumine and identify the incidence of nephrogenic systemic fibrosis (NSF). MATERIALS AND METHODS: An international prospective observational study was conducted from November 2008 to June 2013. A total of 35,499 adults and children who were scheduled to undergo contra…
Al-PTFE (Al-polytetrafluoroethene) is an important kind of Reactive Material (RM), however only limited importance was placed to the effect of crystallinity of PTFE on the mechanical and reactive behavior. This paper investigated the influence of crystallinity on the compression behavior of Al-PTFE at strain rates ran…
N, N -Dimethylamine and N, N -diphenylamine-decorated highly fluorescent imidazole borates have been synthesized and investigated as new fluorophores for the selective detection of trinitrophenol/picric acid (PA). Structural studies of a probe 1 and PA ( 1·PA ) complex revealed that the adduct formed by the deprotonat…
The (1− x )BaTiO 3 – x Bi(Zn 2/3 Nb 1/3 )O 3 ( x = 0.01–0.30) ceramics were synthesized by solid‐state reactions. The solubility limit was determined to be x = 0.20. A systematic structural transition from a tetragonal phase ( x ≤ 0.034), to a mixture of tetragonal and rhombohedral phases (0.038 ≤ x ≤ 0.20), and final…
Over the last ten years a new trend of research activities regarding the flame retardancy of polymeric materials has arisen. Indeed, the continuous search for new flame retardant systems able to replace the traditional approaches has encouraged alternative solutions, mainly centred on nanotechnology. In this context,…
The Bi 3+ /Yb 3+ -codoped gadolinium tungstate phosphor has been synthesized through a solid-state reaction method. The structural characterization reveals the crystalline nature of the phosphor. The Bi 3+ -doped phosphor emits visible radiation from the blue to red regions upon excitation with 330 and 355 nm. The add…
Flexible microsupercapacitors (fMSCs) with interdigitated electrode design are a promising platform as a power source or energy storage unit for wearable microelectronics. In this work, a facile fabrication of all‐solid‐state fMSCs is reported through a combination of simple technologies including bar coating and lase…
Elastic biomaterials are found across biology where they fulfill diverse load-bearing and energy storage and dissipation functions. This class of biomaterials comprises elastic proteins that provide materials with combinations of extensibility, stiffness, tensile strength, toughness, and viscoelastic properties. Diffe…
Gold nanoparticles have particular properties distinct from those of bulk gold crystals, and such nanoparticles are used in various applications in optics, catalysis, and drug delivery. Many reports on microbial synthesis of gold nanoparticles have appeared. However, the molecular details (reduction and dispersion) of…
The Mg97-xZn1Y2Gdx alloys were prepared by as-casting method. Corrosion performance of alloys was evaluated by using potentiodynamic polarization, hydrogen evolution rate and mass loss measurements in 3% sodium chloride solution at room temperature. The results shown that the atomic rate of the long period stacking or…
Microbial polyhydroxyalkanoates (PHA) have been produced as bioplastics for various purposes. Under the support of China National Basic Research 973 Project, we developed synthetic biology methods to diversify the PHA structures into homo-, random, block polymers with improved properties to better meet various applica…
Most commercial elastomers, typified by vulcanized natural rubber, are cross-linked polymers and as such cannot easily be reprocessed or recycled. While some are derived from renewable resources, the majority are produced from petroleum feedstocks and do not easily degrade. In this study, renewable elastomers based on…
