Otoconia, developed during late gestation and perinatal stages, couple mechanic force to the sensory hair cells in the vestibule for motion detection and bodily balance. In the present work, we have investigated whether compensatory deposition of another protein(s) may have taken place to partially alleviate the detri…
Abstract Various polylactic acid (PLA)/cornstarch blends, with and without the compatibilizer methylenediphenyl diisocyanate (MDI), were prepared by melt processing using a twin‐screw extruder. In the blends where it was included, MDI was distributed in either the PLA or starch phase through controlling processes cond…
AA-stacked graphite shows strong anisotropy in geometric structures and velocity matrix elements. However, the absorption spectra are isotropic for the polarization vector on the graphene plane. The spectra exhibit one prominent plateau at middle energy and one shoulder structure at lower energy. These structures dire…
Calcium alginate fibers were treated with vinyl triethoxy silane [H 2 C=CH-Si-(OC 2 H 5 ) 3 ] (5%, v/v) to reduce the strong hydrophilic nature of the fiber and also to improve the mechanical and interfacial properties of the calcium alginate fiber reinforced polypropylene (PP) composites (10 wt% fiber). The composite…
The in situ growth stress and postgrowth stress relaxation during the L1(0) chemical ordering of Fe0.54Pt0.46 thin films have been characterized. The compressive stress is reduced with an increase in order parameter. The postgrowth stress relaxation rate increased with the order parameter and is rationalized in terms…
Advanced surface characterization techniques were used to systematically investigate either the corrosion or passivation of copper after immersion in water as impacted by pH and orthophosphate water chemistries. Atomic force microscopy, depth profiling with time-of-flight secondary ion mass spectrometry, and X-ray dif…
In this work, we presented a facile approach for the preparation of three-dimensional PbS nanoflowers, which was attributed to the coexistence of two types of amines with different-length alkyl chains and different steric hindrance. These monodisperse PbS nanoflowers showed small particle sizes (∼35 nm) and narrow siz…
Abstract In this study, rice‐straw (RS) filled high density polyethylene (HDPE) composites were manufactured by extrusion and injection molding. Three compatibilizers, which are unfunctionalized ethylene/propylene copolymer (uEPR), maleic anhydride grafted EPR (EPR‐ g ‐MA) and PE‐ g ‐MA, and their combinations were in…
Abstract The aerosol‐assisted (AA)CVD reaction of titanium isopropoxide and a solution of preformed tin dioxide nanoparticles leads to the production of titanium dioxide/tin dioxide nanocomposite thin films on glass substrates. Scanning electron microscopy (SEM) studies show that film composition and morphology are li…
In the field of nanometre-sized drug-delivery systems, a wide range of colloidal systems have been created in recent decades. All of the systems have a similar global structure, that is, an inner part and an external surface/interface. In several applications, the external interface is the support for desired properti…
Owing to their scientific and technological importance, inorganic single crystals with highly reactive surfaces have long been studied. Unfortunately, surfaces with high reactivity usually diminish rapidly during the crystal growth process as a result of surface energy minimization. The crystal planes of nickel hydrox…
OBJECTIVE: To accelerate vein graft reendothelialization and reduce vein graft thrombosis by infusing human umbilical cord blood-derived endothelial cells (hCB-ECs) because loss of endothelium contributes to vein graft thrombosis and neointimal hyperplasia. METHODS AND RESULTS: Under steady flow conditions in vitro, h…
The effect of carrier multiplication (CM) in semiconductor nanocrystals is systematically treated by employing an exciton scattering approach. Using projection operators, we reduce the Coulomb coupled multiexciton dynamics to scattering dynamics in the space spanning both single- and biexciton states. We derive a clos…
Janus nanoparticles were prepared by interfacial ligand exchange reactions of octanethiolate-protected gold (AuC8) nanoparticles with 3-mercapto-1,2-propanediol (MPD) at the air/water interface. AFM and TEM measurements showed that the resulting particles formed stable aggregates in water with dimensions up to a few h…
Summary In this study, we aimed to improve the physical properties of Gelidium corneum –gelatin (GCG) film by including nano‐clay in the film‐forming solution and tested the antimicrobial properties of the thymol‐containing composite film as a packaging material for chicken breast. Addition of nano‐clay improved the p…
Bright room temperature visible emission is obtained in heterostructures consisting of approximately 3.5 nm thick ZnO ultrathin films grown on Si-nanowires produced by means of self-masking dry etching in hydrogen-containing plasma. The ZnO films were deposited on Si-nanowires by using atomic layer deposition (ALD) un…
This report describes a simple method for the direct patterning of nanofibers on a flexible, insulating film. The method allows the replication of nanofibrous patterns from a single patterned electrode and the fabrication of multilayered patterns from various electrode shapes. The architecture of the fibrous patterns…
SiCN films were produced by remote microwave hydrogen plasma CVD (RP‐CVD) from tris(dimethylamino)silane precursor using different substrate temperature in the range T S =30‐400°C. The effect of T S on the rate of RP‐CVD, chemical structure, surface morphology, density, and photoluminescence (PL) of resulting films is…
Novel tetragonal scandium orthovanadate crystals doped with neodymium ions (Nd:ScVO 4 ) have been successfully grown with the floating zone (FZ) method for applications in photonic devices. High-temperature stability studies and X-ray structural studies show that thermally induced vanadium oxide vaporization triggers…
Temperature-dependent x-ray powder-diffraction study of the tetragonal compositions of ${\text{PbTiO}}_{3}{\text{-BiFeO}}_{3}$ series has revealed that, unlike for all the known ferroelectric perovskites, the compositions exhibiting giant tetragonality is stabilized from the cubic phase via a complex transition pathwa…
