Abiotic allosterism is most commonly observed in hetero-bimetallic supramolecular complexes and less frequently in homo-bimetallic complexes. The use of hemilabile ligands with high synthetic complexity enables the catalytic center by the addition or removal of allosteric effectors and simplicity is unusually seen in…
High Resolution Image Download MS PowerPoint Slide To identify potential low-temperature thermochemical heat storage (TCHS) materials, hydration/dehydration reactions of M 2 (SO 4 ) 3 (M = Sc, Yb, Y, Dy, Al, Ga, Fe, In) are investigated by thermogravimetry (TG). These materials have the same rhombohedral crystal struc…
Many industry applications required the use of the induction motors. In such envirenement the electrical machines are facing of many stressed operating conditions. One of the critical creteria which decide the choice of the induction motor is the thermal behaviour under different mode operation. In this paper a study…
A straightforward method for the synthesis of two dibenzo[ a, h ]anthracene-5,6,12,13-diquinone building blocks is reported. To showcase their usefulness, a series of dibenzo[ a, h ]anthracene nitrogenated derivatives have been synthesized that show different optoelectronic, redox, and charge transport properties, ill…
In this study, ex-situ Cu-TiC nanocomposites of 1, 3 and 5 vol. % TiC and in-situ Cu-TiH2-C nanocomposites (corresponding to 5 vol. % TiC) were prepared using ball milling and spark plasma sintering methods. Powder mixtures were milled for 4 h at 400 rpm. As-milled Cu-TiC composite powders were consolidated under an a…
Natural biopolymers have found success in tissue engineering and regenerative medicine applications. Their intrinsic biocompatibility and biological activity make them well suited for biomaterials development. Specifically, keratin-based biomaterials have demonstrated utility in regenerative medicine applications incl…

Methyl–ammonium lead, tin, and germanium iodide perovskites are very interesting compounds for photovoltaics because they present a high absorption capacity for solar radiation. The microscopic contributions to the absorption coefficients and efficiencies of these perovskites are analyzed and quantified. To achieve th…
A new CO 2 fixation process was highly enhanced by desilication of serpentine ore with concentrated NaOH solution and NH 3 recycling. In the process, desilicated serpentine containing up to 83 wt % MgO after leaching is treated by NH 4 Cl solution, from which MgCl 2 solution and NH 3 gas are generated and are used to…
We present a theoretical and computational study of thixotropic yield-stress materials in cylindrical Couette flows using a novel fluidity-based constitutive model introduced by de Souza Mendes et al. [J. Nonnewtion. Fluid Mech. 261, 1–8 (2018)]. The model relies on measurable rheological properties to couple the equa…
A one-step sputtering process using a quaternary target has been demonstrated to be a simple route to form Cu(In,Ga)Se 2 (CIGSe) absorber without post-selenization; however, the lack of a Ga-grading structure in the CIGSe absorber confines its efficiency. Here, we demonstrate a one-step cosputtering process to control…
Fullerene micro-/nanostructures with controllable dimensions and explicit morphologies have been widely studied, but such architectures without definitely exposed facets have rarely been reported because of the difficulties in regulating the diffusion behaviors of fullerene molecules at the interfaces. Herein, assumin…
It is well known that near-linear dependencies in the atomic orbital (AO) basis will impede electronic-structure calculations since the inverse AO overlap matrix will be ill-defined. However, small eigenvalues will also impact the locality of the virtual density matrix. The virtual density matrix is relevant for devel…
Great damages to environment will be caused once high pressure buried pipeline leakage leaks occurs. Distributed temperature sensing (DTS) is a good monitoring method of temperature change. Gas from buried pipe leaks is monitored by changes caused by the Joule-Thomson (J-T) effect. In this work, the temperature variat…
Electropulsing has been imposed on molten AISI 304 stainless steel and its effects on the inclusion size and corrosion properties have been investigated. The average size of inclusions in electropulsing-treated samples was finer than that in untreated ones. A theoretical analysis shows that the mobility of solute atom…
Accurately capturing the spatiotemporal information of surface plasmon polaritons (SPPs) is the basis for expanding SPP applications. Here, we report spatio-temporal evolution imaging of femtosecond SPPs launched from a rectangular trench in silver film with a 400-nm light pulse assisted femtosecond laser interferomet…
to the microenvironment. While investigational evidence has shown the unique ability of mEHT to elicit apoptosis in cancer cells, in vivo and in vitro, the same trait has not been observed with conventional HT. There is dissension as to what allows mEHT to elicit apoptosis despite heating to only mild temperatures, wi…
Fluconazole‐resistant Candida albicans is a big scary reality. The authors assessed the antifungal effects of magnetic iron‐oxide nanoparticles on fluconazole‐resistant colonising isolate of C. albicans and determined the expression of ERG11 gene, protein sequence similarity and ergosterol content. C. albicans isolate…
The aim of this study was to determine the activity concentrations of naturally occurring radioisotopes 226Ra, 232Th and 40K in 14 soil samples collected in the Skopje city surrounding, and to calculate the corresponding absorbed gamma dose rates. The radionuclides were measured applying a high purity Ge detector gamm…
Abstract Conventional memory elements code information in the Boolean “0” and “1” form. Devices that exceed bistability in their resistance are useful as memory for future data storage due to their enhanced memory capacity, and are also a necessity for contemporary applications such as neuromorphic computing. Here, wi…
