Pure and europium (Eu)-doped zinc sulfide (ZnS) nanoparticles were synthesized by the solvothermal method and characterized by powder x-ray diffraction (PXRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and photoluminescence (PL). The XRD pattern showed that as-prepared samples…
Magnetic nanoparticles with functionalized surfaces have recently found numerous applications in biology, medicine and biotechnology [1,2]. Some application concern in vitro applications such as magnetic tweezers and magnetic separation of proteins and DNA molecules. Therapeutic applications include hyperthermia [3],…
The synthesis of halide-substituted Mg(BH 4 ) 2 by ball-milling, and characterization with respect to thermodynamics and crystal structure, has been addressed. The ball-milled mixture of Mg(BH 4 ) 2 and MgX 2 (X = Cl, Br) has been investigated by in situ/ex situ synchrotron powder X-ray diffraction (SR-PXD), different…
The mechanical properties of amorphous, degradable, and highly porous poly(lactide-co-caprolactone) structures have been improved by using a 3D fiber deposition (3DF) method. Two designs of 3DF scaffolds, with 45° and 90° layer rotation, were printed and compared with scaffolds produced by a salt-leaching method. The…
Among the distinctive features of quasicrystals-structures with long-range order but without periodicity-are phasons. Phasons are hydrodynamic modes that, like phonons, do not cost free energy in the long-wavelength limit. For light-induced colloidal quasicrystals, we analyze the collective rearrangements of the collo…
Abstract The effect of accumulated deformation and deformation routes in the course of equal‐channel multiple angular extrusion (ECMAE) on physical and mechanical properties of polyethylene (PE) differed in molecular mass (MM) has been studied. As deformation routes, route C (shear planes are parallel, and the simple…
Adipose-derived stem cells (ADSCs) have great potential as a cell source for tissue engineering and regenerative medicine because they are easier to obtain, have lower donor-site morbidity and are available in larger numbers than stem cells harvested using bone marrow aspiration. Until now, little has been known about…
Abstract This study examined the effect of three compatibilizers, namely, a hybrid compatibilizer composed of polypropylene‐maleic anhydride (PP‐ g ‐MAH) and polyethylene‐glycidyl methacrylate (PE‐ g ‐GMA), a single compatibilizer composed of PP‐ g ‐MAH, and a single compatibilizer composed of PE‐ g ‐GMA, on the mecha…
Abstract Poly(melamine‐urea‐formaldehyde) (MUF) microcapsules used as self‐healing component of composites were prepared by in situ polymerization. The surface of MUF microcapsules was modified by 3‐aminopropyltriethoxy silane‐coupling agent (KH550). The interfacial interactions between MUF microcapsules and KH550 wer…
The growth of cooperatively rearranging regions was invoked long ago by Adam and Gibbs to explain the slowing down of glass-forming liquids. The lack of knowledge about the nature of the growing order, though, complicates the definition of an appropriate correlation function. One option is the point-to-set (PTS) corre…
As tissue engineering products move toward the clinic, nondestructive methods to monitor their development and ensure quality are needed. In this study, high-resolution spectral ultrasound imaging (SUSI) was used to noninvasively characterize mineral content in collagen hydrogels. SUSI was used to generate three-dimen…
A general technique for efficient surface modification of silicon nanocrystals is highly desirable for the development of silicon quantum dots (SiQDs) as fluorescent probes for biological applications. Herein, a facile microwave-assisted hydrosilylation process for the preparation of stable SiQDs in a single step is p…
Experimental restrictions imposed on the collection and detection of shortwave-infrared photons (SWIR) have impeded single molecule work on a large class of materials whose optical activity lies in the SWIR. Here we report the successful observation of room-temperature single nanocrystal photoluminescence at SWIR wave…
Polyhexamethylene biguanide (PHMB), a broad spectrum disinfectant against many pathogens, was used as a stabilizing ligand for the synthesis of fairly uniform silver nanoparticles. The particles formed were characterized using UV-visible spectroscopy, FTIR, dynamic light scattering, electrophoretic mobility, and TEM t…
Summary With the advance of new exploration and production technologies, oil and gas production has gone to deeper and tighter formations than ever before. These developments have also brought challenges in scale prediction and inhibition, such as the prevention of scale formation at high temperatures (150–200°C), pre…
Iron oxide magnetic nanoparticles (MNPs) are widely used as diagnostic and therapeutic agents for biomedical applications. Quantitatively analyzing biodistribution, pharmacokinetics and organ clearance of MNPs in mouse models is important for understanding their in vivo behavior. In this study, we developed a novel hi…
Surface nanostructuration was successfully achieved by binding the polyoxometalate (POM) (NBu 4 ) 3 [PW 11 O 39 {(SiC 6 H 4 NH 2 ) 2 O}] covalently onto planar gold surfaces. To do so, POMs functionalized with two terminal amino groups were synthesized and reacted with a mercaptoundecanoic acid self-assembled monolaye…
By means of first-principles calculations, we investigate the effect of halogens on the electronic properties of two-dimensional tin. We found the following: (1) In contrast to the currently accepted view that the Dirac cone characteristic would be deformed upon chemisorption, a new Dirac conelike characteristic of ha…
Continuous fibre-reinforced all-cellulose composite (ACC) laminates were produced in the form of a dimensionally thick (>1 mm) laminate using an easy-to-use processing pathway termed solvent infusion processing (SIP) from a rayon (Cordenka™) textile using the ionic liquid 1-butyl-3-methylimidazolium acetate. SIP facil…
Dendrimers provide many exciting opportunities for potential biomedical applications. However, owing to their positively charged surfaces, poly(propyleneimine) (PPI) dendrimers show toxic and haemolytic activities. One of the methods for masking the peripheral cationic groups is to modify them using carbohydrate resid…
