By means of full electrodynamic simulations, we investigate structures that can totally absorb light minimizing all reflections. Such efficient absorbers of visible and infrared light are useful in photovoltaic and sensor applications. Our study provides a simple and transparent analysis of the optical properties of s…
Lanthanide bioprobes and bioconjugates are ideal luminescent stains in view of their low propensity to photobleaching, sharp emission lines and long excited state lifetimes permitting time-resolved detection for enhanced sensitivity. We show here how the interplay between physical, chemical and biochemical properties…
Optical properties of thin gold films evaporated on glass substrates were studied with the method of spectroscopic ellipsometry in both external and internal reflection configurations as well as with the UV–visible absorption spectroscopy. Here, we discussed how ellipsometric functions Psi and Delta in the spectral re…
Fatigue crack growth (FCG) tests were performed to evaluate the fatigue behaviour of forged Ti–6Al–4V in air and high-pressure gaseous hydrogen (15 MPa) at room temperature. The results indicate that the effect of gaseous hydrogen is dependent on the stress intensity factor (ΔK). The FCG rate was unaffected by hydroge…
The morphology and electronic structure of Cu and Au clusters deposited via thermal evaporation onto ZnO(101̅0) substrates have been studied via scanning tunneling microscopy (STM) and X-ray photoelectron spectroscopy (XPS). The initial stages of nucleation and growth (∼0.2 ML) of both Cu and Au are compared with dens…
The advanced composite materials are increasingly being used in the automotives for their ultralight physical properties and super strong mechanical properties. This research examines the cost‐effective single‐step liquid resin infusion manufacturing process for developing all composite car body as the generally used…
We study the temperature and frequency dependence of the dielectric constant and the ac conductivity in the dimer Mott insulator family ${\ensuremath{\beta}}^{\ensuremath{'}}$-type $\mathrm{Pd}{(\mathrm{dmit})}_{2}$ (where dmit denotes 1,3-dithiole--2-thione--4,5-dithiolate). We find that all compounds within this fam…
Ever increasing use of engineered nanodiamond (ND) into the human blood for various biomedical studies and applications has increased the demand to thoroughly understand the interaction of NDs with blood and its effect on blood coagulation. Here, we report on the study of adsorption of human blood plasma on various si…
The possibility to fabricate marine collagen porous structures crosslinked with genipin under high pressure carbon dioxide is investigated. Collagen from shark skin is used to prepare pre-scaffolds by freeze-drying. The poor stability of the structures and low mechanical properties require crosslinking of the structur…
A better understanding of the essential interaction of semiconductor nanocrystals with their adsorbates and surrounding media can be used for controlling and optimizing the energy or charge transfer reactions found in these systems and also for comparing a diverse assortment of photoexcited charge transfer systems fou…
By virtue of their distinctive electronic properties (including linear energy dispersion, large velocity, and potentially ultra-high mobility even at room temperature), charge carriers in single-layer graphene are uniquely suited to radiation mechanisms that so far have been the primary domain of electron beams in vac…
The grain structure of coarse-grained Cu of different degrees of purity was modified by plastic deformation by , 4 and 8 passes of equal channel angular pressing (ECAP) at an ambient temperature with and without back pressure. The effect of this modification on deformation resistance was tested in rate change tests in…
An organotellurium chain transfer agent (CTA) bearing a triethoxysilyl group at one end and a 2-methyltellanyl-2-methylpropionate group at the other was prepared and immobilized on the surface of a silicon wafer and silica nanoparticle (SiP). Surface-initiated organotellurium-mediated living radical polymerization (SI…
Composite multiferroics are a new class of material where magneto‐electric coupling is achieved by creating an interface between a ferromagnetic and a ferroelectric compound. The challenge of understanding the chemical and magnetic properties of such interface is a key to achieve good magneto‐electric coupling. The un…
Gold nanoparticles on Al 2 O 3 -coated gold films are presented as a chemically and thermally robust platform for molecular sensing. Single particle spectroscopy as a function of Al 2 O 3 coating thickness shows reproducible gold nanoparticle scattering spectra in the range from 690 to 610 nm as the Al 2 O 3 thickness…
Analyses of unipolar charge transport phenomena in series, two-region composite dielectric systems are presented for planar, coaxial cylindrical, and concentric spherical electrode geometries. Space charge limited condition is applied at the charge emitting electrode for steady state and transient. Method of character…
In a recent editorial (Proc. Natl. Acad. Sci., 2013 110, E2144-E2146) and elsewhere, questions have been raised regarding the experimental practices in relation to the proteomic analysis of organic matrices associated to the biomineralized CaCO3 skeletons of metazoans such as molluscan shells and coral skeletons. Inde…
Directed enzyme/prodrug therapy (DEPT) has promising application for cancer therapy. However, most current DEPT strategies face shortcomings such as the loss of enzyme activity during preparation, low delivery and transduction efficiency in vivo and difficultly of monitoring. In this study, a novel magnetic directed e…
2-Methoxyestradiol (2ME), a natural metabolite of estradiol, has antiproliferative and antiangiogenic activity. However, its clinical success is limited due to poor water solubility and poor pharmacokinetic parameters suggesting the need for a delivery vehicle. In this study we evaluated cathepsin B degradable star-sh…
Abstract Two-dimensional boron nitride (BN) nanosheets have attracted increasing attention owing to their diverse functionalities. Here, we developed, for the first time, a solid exfoliation method to prepare few-layer BN nanosheets by ball milling of hexagonal BN (h-BN) with ammonia–borane. We believe this facile and…
