The theoretical foundations, methods, and algorithms developed to analyze the stability and postbuckling behavior of thin elastic axisymmetric shells are discussed. The algorithm for numerically studying the processes of nonlinear deformation of thin-walled axisymmetric shells by the solution parametric continuation m…
For the first time, the power deposition of lower hybrid RF waves into the edge plasma of a diverted tokamak has been systematically quantified. Edge deposition represents a parasitic loss of power that can greatly impact the use and efficiency of Lower Hybrid Current Drive (LHCD) at reactor-relevant densities. Throug…
Abstract Oxygen evolution reaction has attracted extensive attention in energy conversion and storage technology (e. g. water splitting and rechargeable metal–air batteries). Its sluggish kinetics demands effective electrocatalysts to minimize the reaction barrier. Transition metal (oxy)hydroxides with a layered struc…
Abstract BACKGROUND Surface water possesses numerous microbial pathogens due to domestic disposal and poor sanitation. Most of the available conventional disinfection techniques are cost intensive and energy consuming. Being cost effective and environmentally friendly, membrane separation proves to be a better disinfe…
The kinetics of the polymer cross-metathesis reaction in a mixture of polynorbornene and polycyclooctene catalyzed by the Grubbs first-generation ruthenium catalyst at room temperature is studied. The structure of the reaction product, a multiblock copolymer of norbornene and cyclooctene, is determined by a number of…
A new hard X-ray beamline for CATalysis and ACTinide research has been built at the synchrotron radiation facility ANKA. The beamline design is dedicated to X-ray spectroscopy, including 'flux hungry' photon-in/photon-out and correlative techniques with a special infrastructure for radionuclide and catalysis research.…
The temperature distribution in the transformer interior is a significant parameter governing a transformer's performance and life expectancy. In the perspective of the user, temperatures in a transformer are important to determine the amount and duration of over load it can sustain, and to estimate the effects on the…
Thin films Cu2ZnSnS4 (up to 0.9 μm thick) with p-type conductivity and band gap E g = 1.54 eV have been prepared by the spray pyrolysis of 0.1 M aqueous solutions of the salts CuCl2 · 2H2O, ZnCl2 · 2H2O, SnCl4 · 5H2O, and (NH2)2CS at a temperature T S = 290°C. The electrophysical properties of the films have been anal…
Bandgap engineering has been a powerful technique for manipulating the electronic and optical properties of semiconductors. In this work, a systematic investigation of the electronic properties of [0001] GaN nanowires was carried out using the density functional based tight-binding method (DFTB). We studied the effect…
Biomaterials are continually being designed that enable new methods for interacting dynamically with cell and tissues, in turn unlocking new capabilities in areas ranging from drug delivery to regenerative medicine. In this review, we explore some of the recent advances being made in regards to programming biomaterial…
We consider a class of kinetically constrained interacting particle systems on $\mathbb{Z}^{d}$ which play a key role in several heuristic qualitative and quantitative approaches to describe the complex behavior of glassy dynamics. With rate one and independently among the vertices of $\mathbb{Z}^{d}$, to each occupat…
Wireless communications in complex environments are constrained by lossy media and complicated structures. Magnetic Induction (MI) has been proved to be an efficient solution to extend the communication range. Due to the small coil antenna's physical limitation, however, MI's communication range is still very limited.…
Supercapacitors or Electrochemical Double Layer Capacitors, briefly named EDLC, are very promising energy storage components for applications in automotive industry where are intended to be parallel connected to lead-acid or Li-ion batteries or fuel cells. At the beginning of development are the applications in green…
The radiation resistance of nanostructured TiN, TiAlN, and TiAlYN coatings is studied after 500-keV He + ion irradiation in the fluence range 5 × 10 16 –3 × 10 17 ions/cm 2 . The radiation-induced changes in the phase composition, the structure, the lattice parameters, the morphology, and the mechanical properties of…
The nature of the processes that occur when electrodes modified with complexes [M(Schiff)] (M = Ni, Pd, Pt; Schiff denotes four-dentate Schiff base ligands) are irradiated with visible light for the potential use of these electrodes in photoelectrochemical energy conversion devices is considered. The factors responsib…
The aim of this study was to evaluate four different platinated bioconjugates containing a cisplatin (cis-diamminedichloroplatinum [cis-DDP]) fragment and epidermal growth factor receptor (EGFR)-targeting moieties as potential therapeutic agents for the treatment of brain tumors using a human EGFR-expressing transfect…

Apart from its use in hair dyes, resorcinol is \nalso used in several other topical…
The original purpose of the Re-Distribution Layers(RDL) was to assist in the adaption of metal bumping and flip chip packaging technologies, by the addition of the metal and dielectric layers onto the wafer surface to re-route the legacy designed irregular peripheral I/O layout, into a new area array bond pads layout…
In this paper, the generation and steering of beams carrying orbital angular momentum utilizing a custom-designed circular antenna array has been demonstrated at 28 GHz. A steering angle as large as 30 degrees for an orbital angular momentum (OAM) beam has been achieved. The effect of number of antennas and the distan…
