The dynamic relations on the phase interface are derived in the isothermal approximation for liquids in which the dependence of the surface energy on the mass flux across the phase interface must be taken into account. The criterion of stability of subsonic phase-transition fronts with plane waves with respect to smal…
This work studies the surface characteristics, the antimicrobial activity and the aging effect, of plasma pre-treated polyamide 6,6 fabrics (PA66) coated with silver nanoparticles (AgNPs), with the aim to identify the optimum size of nanosilver exhibiting antibacterial properties suitable for manufacturing of hospital…
In order to research the mechanical properties of concrete under impact load, a splitting tensile test of concrete cubes was carried out under the impact load by using the drop test machine. A high-speed camera was used in test to record the crack development process of each specimen. According to box dimension algori…
We perform first-principles calculations on the momentum densities in Fe. The ridge and valley appear on the ∑ and Δ lines, respectively, on the (001) plane. This anisotropic distribution of the momentum densities is found to originate from the difference between symmetries of the ∑( C 2 v ) and Δ( C 4 v ) lines. The…
The present research is dealing with the comparative study of inelastic/elastic behavior of reference ∼12%Cr steel ZL3 and three new trial steels ZU1, ZU2, ZU3, with different ratio of alloying elements and equal content of Cr, using internal friction measurements. The samples were examined in “as-received” condition…
This paper shows the possibility of using the plasmodynamic method for synthesizing ultrafine powders of the Ti–C–N system using different techniques for introducing a precursor. The synthesized powder is analyzed by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, and Raman spectrosc…
Elastomers are necessary materials in building materials. Mouldy materials will not only influence the surface view but also mechanical properties. In this paper, maleoyl chitosan (MCS) was selected as antimicrobial for improving natural rubber (NR) materials' antimicrobial properties together with mechanical and agei…
Hydrogels have attracted much attention for their biocompatibility and tunable properties for use in tissue engineering and regenerative medicine. Cellular adhesion and organization can be controlled by the microstructure of the scaffold. Here, we describe a new cellulose-based bundled hydrogel fiber fabricated by a d…
In recent years, there has been an intense interest in understanding the microscopic mechanism of laser induced ultrafast magnetization dynamics in picosecond time scales. Magnetization switching on such a time scale has potential to be a significant boost for the data storage industry. It is expected that the writing…
Atomically thin two-dimensional nanomaterials such as graphene and transition metal dichalcogenides (TMDCs) have seen a rapid growth of exploration since the isolation of monolayer graphene. These materials provide a rich field of study for physics and optoelectronics applications. Many applications seek to combine a…
A water soluble naphthalenediimide (NDI) selectively interact with small diameter single-walled carbon nanotubes (SWCNTs), as demonstrated by Raman, along with absorption and emission spectroscopies.
Recent studies showed that positron annihilation methods can provide key insights into the nanostructure and electronic structure of thin film solar cells. In this study, positron annihilation lifetime spectroscopy (PALS) is applied to investigate CdSe quantum dot (QD) light absorbing layers, providing evidence of pos…
近年来，多孔配位聚合物在气体储存、分离以及复合光、电、磁等多功能领域具有诱人的前景而备受关注。本文主要采用1-三氮唑-4-四氮唑苯有机配体分别与铜(I)、银(I)离子自组装得到2个新颖的配位聚合物，并对其组装规律和构效关系进行探索。 Recently, porous coordination polymers (PCPs) have attracted great interest on account of their potential application in gas storage and separation, and as optoelectronic and magnetic materials. In this…
This investigation deals with the magneto-optical properties of pure and manganese doped ZnO thin films in the spectral region 600 – 1200 nm. The spectra of Verdet constant (V) are determined in the same spectral region for these thin films. The magneto-optic anomaly factor γ has been expressed. The spectral dependenc…
Unsubstituted phthalocyanines of Co, Fe and Mn supported on zinc oxide nanoparticles were prepared and were well characterized with X-ray diffraction and scanning electron microscopy. The oxidation of alcohols with tert-butylhydroperoxide, in the presence of metallophthalocyanines supported on zinc oxide nanoparticles…
Electricity generation by single-chamber air cathode fuel cells (MFCs) is considerably influenced by power management system(PMS). This study showed that application of PMS connected with a single-chamber air cathode MFC significantly improved its columbic efficiencies (CEs), current, and power output. In MFC tests ba…
The paper presents a solution of the analysis concerning the behavior of the steel lattice girder under a cycle of dynamic impulse I=P·τ 0 . In this analysis I usethe theory of shakedown. I assume that this load causes anon elastic reaction which it contain dissipation of energy, so we have to continue the deformation…
The effects of two thermal annealing steps on the crystallographic orientation, film stress and crystal domain size in RF-magnetron sputtered ZnO thin films for ultrasonic transducers were investigated. As-grown films contained high levels of compressive stress introduced by the sputtering process, as well as low (002…
The physicochemical, thermomechanical, and elastic-strength characteristics of samples based on an oligoetheracrylate binder cured both under the action of only coherent UV radiation and with subsequent aftercuring in a UV oven were studied. It was established by differential scanning calorimetry that full curing of t…
