Recruitment of mesenchymal stromal cells (MSC) into the field of tissue engineering is a promising development since these cells can be expanded vivo to clinically relevant numbers and, after expansion, retain their ability to differentiate into various cell lineages. Safety requirements and the necessity to obtain hi…
Abstract To understand the oxidation state, coordination geometry, and physicochemical behavior of the Eu3+ complex with dihexyl N,N‐diethylcarbamoylmethylphosphonate (DHDECMP) in the ionic liquid (IL) 1‐butyl‐3‐methylimidazolium bis(trifluoromethylsulfonyl)imide ([bmim][NTf2]), the spectroscopic and electrochemical p…
Nanofiber formation of a mixture of Fe 0 , oxyhydroxides and oxides iron formed after water remediation processes to reduce cadmium concentration.
Carbon nanotubes (CNTs) were coated TiO 2 nanoparticles via sol–gel process using titanium tetra-isoproxide Ti[OCH(CH 3 ) 2 ] 4 (TTIP). The structure of TiO 2 /CNT hybrid samples was determined by x-ray diffractometer D5005 (Siemen) with CuK α radiation. Their morphology and sizes were investigated with FE-SEM and HR-…
Phase change nanofibers based on polyamide 6 and polyethylene glycol, in which polyethylene glycol acted as a model phase change material and polyamide 6 acted as a supporting material, were successfully prepared via electrospinning. Morphology, compatibility, thermal stability, thermo-regulated performance and physic…
In this paper, we propose a surface acoustic wave (SAW) sensor with a Ag-doped ZnO nanoparticle film for low-intensity ultraviolet (UV) light detection. With this sensor, Ag doping is shown to effectively enhance ZnO thin film conductivity, thereby improving the SAW sensor sensitivity. Furthermore, it also enlarges th…
Porous coordination polymers (CPs) with partially uncoordinated pyridyl rings based on rationally designed polypyridyl linkers are appealing from the point of view of their application as nucleophilic catalysts. A D2d -symmetric tetradentate organic linker L, that is, 2,2',6,6'-tetramethoxy-3,3',5,5'-tetrakis(4-pyridy…
A biocompatible and biodegradable hydrogel based on a natural polysaccharide was prepared, characterized and confirmed to be an effective and “smart” carrier for controlled protein delivery.
Although polymer solar cells (PSCs) have received a tremendous amount of attention in recent years, a number of criteria must be met in order for them to be suitable as practical and commercially feasible power sources, including high performance, good air stability and inexpensive manufacturing. In this contribution,…
Abstract The potential for expanding the variety of catalytic methods for siloxane bond formation is explored. Alkoxysilanes react with methylallylsilanes in the presence of scandium(III) trifluoromethanesulfonate to yield disiloxanes and isobutene. The reaction proceeds through one‐pot hydrolysis/ O ‐silylation of al…
We discuss the well-posedness of a new nonlinear model for nematic elastomers. The main novelty in our work is that the Frank energy penalizes spatial variations of the nematic director in the deformed, rather than in the reference configuration, as it is natural in the case of large deformations.
In the present work, it is shown that the friction stress of ethylene glycol can decrease by an order of magnitude to achieve superlubricity if there are hydrogen ions attached on the friction surfaces. An ultra-low friction coefficient (μ = 0.004) of ethylene glycol between Si3N4 and SiO2 can be obtained with the eff…
Gold nanoparticles (AuNPs) have been deposited on n-type Ge photodetectors to improve the responsivity. Two different coverage ratios, including 10.5 and 30.3% of AuNPs have been prepared, and the fabricated photodetectors are compared with the control sample. The 1,310-nm responsivities at -2 V of the control, 10.5%…
Geopolymer composites reinforced with different layers of woven flax fabric are fabricated using lay- up technique. Mechanical properties, such as flexural strength, flexural modulus and fracture toughness of geopolymer composites reinforced with 2.4, 3 and 4.1 wt% flax fibres are studied. The fracture surfaces of the…
Three new structurally diverse zinc(II) complexes of formula [H3O][ZnL2]ClO4 (1), [Zn2(μ-L)2(NCS)2] (2) and [Zn3(μ-L)2(μ-N3)4]n (3) have been synthesized using the same furan-based tridentate ONO-donor Schiff base ligand HL (2-hydroxybenzyl-2-tetrahydrofurylmethyl)imine and characterized by X-ray structural analysis.…
An issue in the application of nano-enabled products is how can we evaluate sustainable solutions to current system problems based on performance criteria? This work describes the application of an Input–Process–Output (IPO) model as a framework for a life-cycle analysis approach to identify performance metrics and cr…
Several Na–S solid phases have been considered to be produced in low-temperature Na/S batteries during charge–discharge reactions. We study structural and electronic properties of α-S and Na2Sx (x = 1, 2, 4, and 5) crystals using first-principles calculations. Calculated structural properties are in good agreement wit…
In this study, a photoelectrochemical glucose biosensor is presented, comprising electropolymerized hematoxylin film on poly-amidoamine (PAMAM) dendrimers adsorbed on glassy carbon electrode (poly-HT/PAMAM/GCE).
We numerically demonstrate that a broadband electromagnetically induced transparency–like (EIT-like) effect can be achieved in an all-dielectric microstructure consisting of a dielectric bar and six dielectric bricks. With proper excitations, the dielectric bar and bricks serve as bright and dark elements via the Mie…
Donor-acceptor molecules (D-π-A) built by connecting a diphenylhydrazone block to a dicyanovinyl acceptor group via various thiophene-based π-conjugating spacers (1-5) were synthesized from mono- or dialdehydes by a simple metal-free procedure. Cyclic voltammetry and UV/Vis absorption spectroscopy show that the extens…
