thin films -- zinc oxide -- metallic Co nanoparticles -- magnetic properties -- magnetic circular dichroism spectroscopy -- giant magnetoresistance effect
Аннотация: ZnCoO:H and ZnCoAlO:H films were synthesized by radio frequency magnetron sputtering in a (1 − x)Ar + xH2 mixed atmosphere with x = 0.2–0.5. The films contain different amounts of metallic Co particles (from 7.6% and higher) ~4–7 nm in size. The magnetic and magneto-optical (MO) behavior of the films was analyzed in combination with their structural data. The samples exhibit high values of magnetization (up to 377 emu/cm3) and MO response at room temperature. Two situations are considered: (1) the film magnetism is associated only with isolated metal particles and (2) magnetism is present both in the oxide matrix and in metal inclusions. It has been established that the formation mechanism of the magnetic structure of ZnO:Co2+ is due to the spin-polarized conduction electrons of metal particles and zinc vacancies. It was also found that in the presence of two magnetic components in the films, these components are exchange-coupled. In this case, the exchange coupling generates a high spin polarization of the films. The spin-dependent transport properties of the samples have been studied. A high value of the negative magnetoresistance of the films at room temperature (~4%) was found. This behavior was explained in terms of the giant magnetoresistance model. Thus, the ZnCoO:H and ZnCoAlO:H films with high spin polarization can be considered as sources of spin injection.

Manganese and zinc halides -- Pefloxacin -- Ionic compounds -- Photoluminescence -- X-ray diffraction -- Thermal decomposition
Аннотация: Mn2+-based hybrid materials have become the hotspot of current research studies owing to their high photoluminescence quantum yield (PLQY), low-cost, environmental friendliness and stability. For the first time, we report the hydrothermal synthesis of two lead-free zero-dimensional luminescent organic-inorganic hybrid compounds, PefH2[MnBr4] (1) and PefH2[MnCl4] (2) (Pef = pefloxacin). They were characterized by elemental analysis, TG-DSC, single-crystal and powder XRD. Compounds 1–2 exhibit a distorted tetrahedral geometry around the manganese(II) metal center, which is isolated from the same centers by bulky pefloxacindi-ium (PefH22+) ions with a Mn···Mn distance of 7.3 Å. Their structures are stabilized by N—H···O, O—H···X (X = Br, Cl), C—H···O and C—H···X hydrogen bands and π–π stacking interaction. Thermal decomposition starts at T › 230°С for 1 and T › 210°С for 2 and proceeds for several stages. Upon UV excitation compounds exhibit a bright green emission with a moderate PLQY of 45% for 1 and 30% for 2. The influence of the halide ion and metal ion on the photoluminescence properties of isostructural compounds PefH2[MX4] (M = Mn, Zn and X = Br, Cl) is discussed.

Аннотация: The pillared layer framework DUT-8(Zn) (Zn2(2,6-ndc)2(dabco), 2,6-ndc = 2,6-naphthalenedicarboxylate, dabco = 1,4-diazabicyclo-[2.2.2]-octane, DUT = Dresden University of Technology) is a prototypical switchable MOF, showing characteristic adsorption and desorption induced open phase (op) to closed phase (cp) transformation associated with huge changes in cell volume. We demonstrate switchability strongly depends on a framework-specific critical particle size (dcrit). Superposed, the solvent removal process (pore desolvation stress contracting the framework) significantly controls the cp/op ratio after desolvation and, subsequently, the adsorption induced switchability characteristics of the system. After desolvation, the dense cp phase of DUT-8(Zn) shows no adsorption-induced reopening and therefore is non-porous for N2 at 77 K and CO2 at 195 K. However, polar molecules with a higher adsorption enthalpy, such as chloromethane at 249 K and dichloromethane (DCM) at 298 K can reopen the macro-sized crystals upon adsorption. For macro-sized particles, the outer surface energy is negligible and only the type of metal (Zn, Co, Ni) controls the DCM-induced gate opening pressure. The node hinge stiffness increases from Zn to Ni as confirmed by DFT calculations, X-ray crystal structural analysis, and low frequency Raman spectroscopy. This softer Zn-based node hinges and overall increased stabilization of cp vs. op phase shift the critical particle size at which switchability starts to become suppressed to even lower values (dcrit ‹ 200 nm) as compared to the Ni-based system (dcrit ≈ 500 nm). Hence, the three factors affecting switchability (energetics of the empty host, (Eop–Ecp) (I), particle size (II), and desolvation stress (III)) appear to be of the same order of magnitude and should be considered collectively, not individually.

Аннотация: A zinc sulfate film is deposited from aqueous solutions of zinc sulfate onto the gold surface with the aim of preparation of a sensor for electrochemical quartz crystal microbalance (EQCM). The kinetics of this process, the particles formed in solution, and the film itself are studied by the methods of electrochemical quartz crystal microbalance, X-ray photoelectron spectroscopy, transmission electron microscopy, atomic force microscopy, optical and Raman spectroscopies, and dynamic light scattering. The effect of the procedure of gold surface preparation, the reagent concentration, and the temperature on the film adhesion, the length of induction period, the kinetics of film growth, and its structure and thickness are studied. It is shown that the film formation proceeds as a result of deposition of sufficiently coarse 200-700 nm colloid particles of sphalerite. It is demonstrated that this sensor can be used in studying the electrochemical reactions of ZnS and the interface phenomena by the methods of EQCM and cyclic voltammetry.

Zinc oxide -- Amorphous carbon -- Multi-layered structures -- Composites -- Hopping conductivity -- Weak localization -- Magnetoresistance
Аннотация: ZnO- and C-based heterostructures were fabricated by the layer-by-layer deposition technique using the ion-beam sputtering process. Structure, electrical and magnetic properties of fabricated heterostructures are discussed. The two-phase (ZnO and C) films are evolved into a multilayer structure, consisting of amorphous carbon and crystalline ZnO layers when the bilayer thickness increases. When carbon is added to ZnO, its electrical resistivity reduces. The conduction mechanism changes from the variable-range hopping in a narrow energy band to the nearest neighbors hopping in ZnO–C films with a thickness of h ˂ 150 nm. The temperature dependence of conductivity changes from the Arrhenius-like to logarithmic law, indicating that the strong charge localization turns into a weak one when the film thickness is about 150 nm. The negative magnetoresistance of up to 1% was detected at 77 K. The film ferromagnetism at the temperature of 10 K was not found.

Аннотация: We demonstrate the possibility of using transparent conducting oxides [aluminum-doped zinc oxide (AZO), gallium-doped zinc oxide (GZO), indium tin oxide (ITO)] to form Tamm plasmon polaritons in the near-infrared spectral range where the permittivity of oxides is near zero. The spectral properties of the structures are investigated in the framework of the temporal coupled-mode theory and confirmed by the transfer matrix method. It is found that in the critical coupling conditions, the maximal Q-factor of a Tamm plasmon polariton is achieved when a photonic crystal is conjugated with the AZO film, while at the conjugation with the ITO films, the broadest spectral line is obtained. The sensitivity of the wavelength and spectral width of the Tamm plasmon polariton to changes in the oxide film thickness, bulk concentration of a dopant, and angle of incidence is demonstrated.

Аннотация: The present study describes the synthesis of silver and zinc oxide nanobactericides from the phytogenic source Bupleurum aureum The synthesized nanobactericides were characterized and evaluated for bio-functionalization onto bacterial cellulose membrane which was synthesized by Komagataeibactencylinus B-12068 culture strain. The synthesis of nanobacterides were initially confirmed using UV-Visible spectroscopy which indicated localized surface resonance (LSPR) peaks at 415 nm for silver nanobactericides and 280 nm for zinc nanobactericides. The nature of the capping agent for synthesized nanobactericides was predicted using FTIR which confirmed the presence of functional moieties. XRD analysis revealed their crystalline nature while morphological characteristics were studied using TEM which confirmed the polydispersity of nanobactericides with the average size in the range of 20-25 nm. The nanobactericides were tested for their antimicrobial activity against seven multi-drug resistant pathogens which were clinically isolated from patients suffering from a myriad of microbial infections. The tested pathogens had antimicrobial resistance to ten different antibiotics and have been reported to be the major cause of nosocomial infections. The nanobactericides displayed significant activity against the test pathogens. Silver nanobactericides showed the highest activity against Escherichia coli strain 55 with a 24 mm zone of inhibition while zinc oxide nanobactericides displayed the highest activity against methicillinresistant Staphylococcus aureus (MRSA) with a 20 mm inhibition zone. The bio- functionalized cellulose films (BCF) were characterized using SEM along with physicochemical analysis. The BCF's were evaluated for anti-bacterial activity against test pathogens which resulted in marked antimicrobial potential against multi-drug resistant bacteria and therefore has the potential to be utilized as an efficient alternative to counter drug resistant pathogens.

Аннотация: The theoretical and experimental substantiation of the behavior of ferrous sphalerite in magnetic separation is given in terms of the Gorevka deposit ore. In sphalerite of this deposit, the content of isomorphous iron ranges as 4-9%. The Mossbauer spectroscopy showed the singlet and two doublet lines of iron, demonstrating separate arrays of iron atoms in sphalerite lattice, with formation of Fe-Fe pairs and clusters of three or more iron atoms. It is found that distribution of iron in sphalerite into three forms coincides for magnetic and nonmagnetic products of zinc concentrate separation. It is determined that magnetic separation undivides sphalerite grains by the isomorphous iron content but is governed by the genetic features of the deposit formation-association of sphalerite with magnetic minerals (pyrrhotine and siderite) and the absence of such associations in galena.
