Abstract New schiff base bis (salicylidene) tetramethylbenzidine (bstmb) was prepared via the condensation of salicylaldehyde with 3, 3−, 5,5−-tetramethylbenzidine in an ethanol solution. Four complexes were prepared by reaction of schiff base with metal acetat where m(ii),[co, ni, cu, and zn]. The schiff base ligand…
The reactions of tetraorganylphosphonium and trimethylammonium chlorides with hexachloroplatinic acid hydrate in an acetonitrile–diethyl sulfoxide solution produced [Ph 3 PCH=CHCH 3 ] 2 [PtCl 6 ], [Ph 3 PCH 2 OCH 3 ] 2 [PtCl 6 ], and [Me 3 NH] 2 [PtCl 6 ] complexes. The structure of the resultant platinum complexes wa…
Geopolymer samples prepared through alkali activation of metakaolin under varying conditions of synthesis (100°C (14 h); 130°C (3 h); clinoptilolite filler) are employed as formaldehyde sorbents from aqueous solutions. The structure and physicochemical properties of geopolymer sorbents are studied using XRD, XRF, SEM,…
This paper presents a reconfigurable band of operation from 5G to 4G for radio frequency energy harvesting (RF-EH) in the different wireless communication bands. The designed antenna with steerable beam pattern based on tunable of the graphene pads. The proposed antenna consists of printed CPW-fed circular monopole sh…
Abstract The work reports on the interaction of the photo electrodes with the electrolytes and dyes since it is imperative to investigate the degradation behavior of the transparent conducting electrodes in terms of structural, optical and electrical properties along with the corrosion resistance behavior. Three elect…
General information about ice-wind accidents on overhead transmission lines (OHL) in distribution electric networks is given/ The authors point to the need for an ice melting system on OHL wires which is confirmed by operating experience and regulatory documents. Innovative solutions for the ice melting system on the…
Due to the excessive use of chemical agents in agriculture, numerous problems have arisen, such as contamination of the environment, intoxication of non-target organisms and the development of resistance mechanisms by pests. To overcome these challenges, several sustainable technological approaches are being explored,…
Abstract We studied the surface morphology and biocompatibility of hydrogenated amorphous silicon-germanium (a-Si1-xGex:H) thin films prepared by Low Frequency Plasma Enhanced Chemical Vapor Deposition (LF-PECVD). These films were deposited on a Corning 2947 glass substrate having a thickness of 3 μm, the electrical p…
Abstract Pericarps of Algerian Quercus ilex ( Q. ilex ) and Quercus suber ( Q. suber ) were used as copper adsorbents in artificially contaminated solutions. Exposing accessible lignocellulosic binding sites enhanced adsorption. The lignocellulosic fractions of Q. suber and Q. ilex (36.47±9.1 and 47.66±9.3, respective…
Abstract The main task of any vascular stent is the mechanical support of the re-opened vessel. This support function may be quantified by the compressive properties of the stent in radial outer loading conditions. Different test methods are standardized and are accepted to provide relevant data. Six commercially avai…
Abstract— We have studied the effect of hydrostatic pressure on the galvanomagnetic properties of a Cd3As2 + 20 mol % MnAs alloy in a transverse magnetic field of up to 4 kOe. The pressure dependences of the Hall coefficient and resistivity for the alloy provide evidence of reversible phase transitions. The observed n…
Abstract In this work, a low-priced smart fabric forcesensing glove is developed which is able to measure the total amount and direction of the force a person applies on a patient in a physiotherapeutic context. A device like this would be beneficial for the education of physiotherapists, to measure the progress of a…
Abstract We have developed a new low-cost method for fabrication of an enhanced porosity ultra-low noise silver-silver chloride (Ag-AgCl) reference electrode with dramatically high stability, useful in precise electrochemical and biomedical measurements. Low noise level and high stability are the most important featur…
ABSTRACT In this study, Fe@Fe 2 O 3 nanowires were applied in combination with electro Fenton (EF) process to decompose of carbamazepine (CBZ) drug in an electrochemical reactor using a graphite rod cathode and Ti/PbO 2 anode. Response surface methodology (RSM) based on central composite design was used to optimize va…
Abstract The results of experiments aimed at the observation of split 1s states in Mg-doped Si are reported. From the results, it is possible to determine the chemical shift and exchange interaction energy of a neutral Mg donor in Si. The position of the 1s(E), 1s(T2), and 2s(A1) parastates determines the possibility…
The suitability of natural ester oils as an insulating medium in power transformers is discussed in this paper. Owing to environmental concerns, natural ester oils have great potential as mineral oil substitutes in power transformers. In this paper, the aging behaviors of palm and rapeseed natural ester oils were comp…
Abstract In this paper, we discuss the possibility of unexplored behaviours for the entanglement entropy in extended quantum systems. Namely, we study the Rényi entanglement entropy for the ground state of long-range Kitaev chains with slow decaying couplings. We obtain that, under some circumstances, the entropy grow…
The radiation qualification of a complex space system made out of multiple commercial electronic components and modules is a non-standardized task with certain limitations, but also wide potentialities. This paper delves into the features of a system-level test methodologies and explains how to use the data retrieved…
Background: To evaluate the efficacy and safety of liposome-paclitaxel (L-PTX)/L-PTX plus S-1 in advanced gastric cancer patients with poor performance status (PS). Methods: We performed this retrospective study on 17 advanced gastric cancer patients with poor PS [rated as ≥2 based on the Eastern Cooperative Oncology…
