X-ray structures of gold corroles, which are still rather uncommon, afford significant insights into intermolecular interactions involving Au(III), a subject that has been much less studied than aurophilic and metallophilic interactions involving Au(I). The X-ray structure of gold [Formula: see text]-octabromo-meso-tr…
For efficient conversion of light into useful energy sources, it is very important to study and describe the first steps of primary charge-transfer process in natural structures and artificial devices. The time scale of these processes in artificial photosynthetic and photovoltaic devices is on the order of femto- to…
Abstract Microbes accumulate heavy metals after adsorption or absorption. This study exhibited that Trametes versicolor can tolerate up to 5 mg/g concentration of cadmium. Change in fungus morphology due to cadmium along with its absorption were analyzed using SEM, XRD, and EDAX. Cadmium absorption usually increased w…
Mesoporous silica nanoparticles (MSNs) are exceptionally promising drug carriers for controlled drug delivery systems because their morphology, pore structure, pore volume and pore size can be well tailored to obtain certain drug release profiles. Moreover, they possess the ability to specifically transport and delive…
Flexoelectricity is thought of as a universal property of all dielectric materials that couples polarization with the inhomogeneous deformation. However, at the macroscale, this coupling is usually very weak and the direct observation of flexoelectricity always suffers from a low signal-to-noise ratio (SNR). At the mi…
Abstract A high-transparency ZnO thin film of high carrier concentration was grown by conventional RF sputtering, where the carrier concentration was continuously varied from 10 16 to 10 19 cm −3 by controlling the amounts of O 2 and H 2 sputtering gases. To prevent the formation of a Schottky junction at the contact…
It has been recently shown that in the presence of an applied voltage, hydrogen and deuterium nuclei can be separated from one another using graphene membranes as a nuclear sieve, resulting in a 10-fold enhancement in the concentration of the lighter isotope. While previous studies, both experimental and theoretical,…
Abstract: Objectives: Nanoparticles synthesis via green approach is a scorching theme of research nowadays as it minimizes the use of harmful chemicals. Not much work has been done on bio reduction of copper salts; therefore our present work was focused on green synthesis of copper oxide nanoparticles using leaf extra…
This work presents the recovery of thermal energy through the oscillation of liquid plugs induced by phase transition within the oscillating heat pipe (OHP) during the quick heat-transfer process of the OHP. Using the electrical double layer at the liquid-solid interface in the OHP, this study demonstrated that the wa…
Alternating current (ac) bipolar electropolymerization of 3,4-ethylenedioxythiophene (EDOT) was performed in the presence of hexachloroplatinate ([PtCl 6 ] 2– ) or poly(styrenesulfonate) (PSS). We demonstrated that both [PtCl 6 ] 2– and PSS were successfully incorporated into electrogenerated poly(3,4-ethylenedioxythi…
Abstract The usual way to prepare TaC‐TaB 2 ceramics by adding B 4 C to TaC leads to formation of residual C, which degrades samples’ mechanical properties. To eliminate the residual C, we suggest incorporating Si together with B 4 C into TaC ceramics, resulting in new ultrahigh‐temperature ceramics (TaC‐TaB 2 ‐SiC).…
Core-shell gallium nanoparticles (Ga NPs) have recently been proposed as an ultraviolet plasmonic material for different applications but only at room temperature. Here, the thermal stability as a function of the size of the NPs is reported over a wide range of temperatures. We analyze the chemical and structural prop…
Abstract The use of nanoparticles in nanomedicine has received increasing interest. However, in vivo detection of nanoparticles using optical techniques is still a formidable challenge. Detecting surface‐enhanced Raman scattering (SERS)‐labeled nanoparticles through thick tissue is crucial due to its large number of p…
Abstract The heterotrimetallic complexes [FeMFe(dpa) 4 Cl 2 ] (M=Ni ( 1 ), Pd ( 2 ), and Pt ( 3 ); dpa − =dipyridylamido) featuring two high‐spin iron centers linked by Group 10 metals were synthesized and their physical properties were investigated. Oxidation of 1 – 3 with suitable oxidants in CH 2 Cl 2 solution yiel…
In this paper of thermoelectric generators, metals are used as the prospective thermoelectric materials or thermoelements on flexible copper (Cu)-clad polyimide substrate. The fabricated thick film generators have planar and lateral structures with lateral heat flow and lateral thermopile layout. Hereby, two prototype…
Graphene has recently attracted particular interest as a flexible barrier film preventing permeation of gases and moistures. However, it has been proved to be exceptionally challenging to develop large-scale graphene films with little oxygen and moisture permeation suitable for industrial uses, mainly due to the prese…
Graphene is a promising two-dimensional nanomaterial for many applications due to its exciting properties. In the past decade, a variety of techniques-each with its own set of advantages and disadvantages-have been developed to prepare graphene, and there are ongoing efforts to improve these techniques and to reveal n…
Dust, which can be seen almost everywhere in real life, often dirties the building, car, cloth, and so on. Humans have come up with many ideas to wash it out for a cleaner world. While in the point of material researchers, dust is composed of particles in different scales. In this work, for the first time, we try to m…
Abstract Conventional approaches to preparing highly fluorinated multiwalled carbon nanotubes (MWCNTs) always require a high temperature. This paper presents a catalytic approach to realizing the effective fluorination of MWNCTs at room temperature (RT). Fe 3 O 4 /MWCNTs composites with Fe 3 O 4 loaded on MWCNTs were…
Novel water-dispersible hybrid iron oxide nanoparticles grafted with a polymeric analogue of dimethyl sulfoxide (DMSO) were prepared. Superparamagnetic iron oxide nanoparticles with immobilized atom-transfer radical polymerization (ATRP) initiators were prepared via an in situ method using 12-(2-bromoisobutyramido)dod…
