The continuous growth of nanotechnology has brought challenging innovations in medicine, revolutionising the eld of diagnosis and therapy. Indeed, in the eld of the synthesis and functionalisation of inorganic nanoparticles (NPs) for biomedical applications, most researches aim at developing multifunctional theranos…
DNA-templated fluorescent silver nanoclusters (Ag NCs) composed of several or tens of atoms are gaining much interest because of their unique properties and convenient emission tunability by DNA sequence and length. However, the modulation by other factors other than DNA is also dependent on the special DNA secondary…
Tarbagataite, (K,□) 2 (Ca,Na)(Fe 2+ ,Mn) 7 Ti 2 (Si 4 O 12 ) 2 O 2 (OH) 4 (OH,F), is a new Ca- and Fe 2+ -dominant astrophyllite-group mineral discovered in a pegmatite in the Verkhnee Espe deposit, Akjailyautas Mountains, Kazakhstan. Tarbagataite occurs as intimate intergrowths of tarbagataite and astrophyllite flake…
In order to create new biodegradable systems for the targeted transport of drugs, poly(3-hydroxy-butyrate) films containing the antibiotic rifampicin in an amount of 5–15 wt % as a model drug are prepared. Film surfaces are studied via scanning electron microscopy, and various structural elements (globules and fibrils…
Silicon carbonitride layers have been obtained by chemical deposition from the gas phase with thermal (LPCVD) and plasma (PECVD) activation of the gas mixture of helium with the new volatile siliconorganic compound tris(diethylamino)silane (Et 2N)3SiH (TDEAS) in the temperature region 373–1173 K. Thermodynamic simulat…
We investigate the lattice dynamics in both nonmagnetic and striped antiferromagnetic states of “111”-type iron pnictides using the density-functional perturbation theory. The anisotropic spin-phonon effects lead to the softening of phonon frequencies and the renormalization of electron-phonon matrix elements, so as t…
The effect of mutual inductance on the performance of a pair of Metglas/Pb(Zr,Ti)O3 laminate magnetoelectric (ME) sensors has been studied. The effective value of the ME coefficient (αME) for the laminates was reduced when the distance between was < 40 mm. Separating the two laminates by distances of > 4…
A facile method is presented for the electrospinning of multiple polymer jets into nanofibers. The experiments in this study electrified 7 wt% polyethylene oxide (PEO) and 10 wt% poly(vinylidene fluoride) (PVDF) solutions and adopted porous materials (bars with various dimensions) to enhance the productivity of the el…
Films of Er 2 O 3 grown on Si(111) substrates by rf-magnetron sputtering were characterized by synchrotron radiation X-ray diffraction and photoluminescence spectroscopy in spectral and time domains. We measured the photoluminescence and the intensity ratio of the peaks in the photoluminesence as a function of tempera…

In this study, starch/polyvinyl alcohol (PVA)/titanium oxide (TiO2) nanocomposite films were synthesized using a casting method. The characteristics of the starch/PVA nanocomposite films were evaluated by a scanning electron microscope (SEM), and X-ray diffraction (XRD). The physical properties such as tensile strengt…
In today's state-of-the-art designs, bulky magnetic components pose major barriers to integrate a DC/DC converter into a single chip. One of the promising technologies to integrate the magnetic component with the active component is three-dimensional (3D) integration, using a low-profile inductor as the substrate. In…
A new electrochromic copolymer of 2,2′:5′,2″-terthiophene (TT) with 3,4-ethylenedioxythiophene (EDOT) was synthesized in 0.1 M tetrabutylammonium perchlorate as supporting electrolyte and characterizations of the resulting copolymer P(TT-co-EDOT) performed by cyclic voltammetry, UV–vis spectroscopy, scanning electron…
Abstract Summary: Linear olefin block copolymers (OBCs) are novel polyolefins with unique properties developed using the chain shuttling polymerization technology. Typically, OBCs are made in a single reactor with two catalysts having different 1‐olefin reactivity ratios and a chain shuttling agent (CSA), producing li…
Abstract A series of Keggin‐type polyoxometallates, M 3 (PW 12 O 40 ) 2 [M=Ni, Zn, Co, Mn, Cu], FePW 12 O 40 , Ni 3 (PMo 12 O 40 ) 2 and Ni 2 SiW 12 O 40 , were prepared and used as catalysts for selective oxidation of benzyl alcohol into benzaldehyde with H 2 O 2 as an oxidant under solvent‐free condition. Ni 3 (PW 1…
Abstract. We investigate transport in a three-terminal graphene quantum dot. All nine elements of the conductance matrix have been independently measured. In the Coulomb blockade regime accurate measurements of individual conductance resonances reveal slightly different resonance energies depending on which pair of le…
A series of B 3 core-terminated highly branched siloxane–urethane polymers was synthesized through the A 2 + B 3 route. Isophorone diisocyanate (IPDI)-terminated polydimethylsiloxane (PDMS) was used as the A 2 unit and triethanol amine as the B 3 core. Size exclusion chromatography (SEC) studies revealed decreasing nu…
Metal-free and copper(II) tetra-β-polyethyleneoxide-substituted phthalocyanine derivatives, TDEO6-MPc, where polyethylene oxide derivative is hexaethyleneglycolmonododecylether (DEO6), were synthesized. Those compounds are soluble in both lipophilic and hydrophilic solvents. By taking advantage of this amphiphilic pro…
Nanostructured multilayer alloy or composition modulated multilayer alloy coatings of Zn–Co have been developed, and their corrosion behaviours were studied by potentiodynamic polarisation and electrochemical impedance spectroscopy methods. The coatings were developed galvanostatically using square, triangular and saw…
