Abstract: “Quantum dot (QD)” or, other name, “quantum box”, represents an ultimate case of size quantization in solids, where the motion of the charge carriers is restricted in all three dimensions (3D). The critical condition for the formation of truly atom-like density states is a high quality of interfaces surrounding such nano-objects. [..] Read more

Abstract: Term and concept of a new branch of science and technology, namely, “nanoionics”, were formulated in IMT RAS (1991-1992). It was the article "A step towards nanoionics". [..] Read more

Abstract: Advanced superionic conductors (AdSICs) have the best ion-transport properties. These properties are determined by the AdSIC crystal structure that is close to optimal for fast ionic transport (FIT). [..] Read more

Abstract: Lead sulfide (PbS) quantum dots (QDs) have been covalently attached to reduced graphene oxide (rGO). Thin films from a hybrid rGO-PbS nanomaterial have been formed by a Langmuir-Blodgett technique. [..] Read more

Abstract: This study addresses the effects of atmospheric-pressure plasma on the properties of methylammonium lead halide perovskite thin films. Plasma-treated films then were used to fabricate an inverted p-i-n perovskite solar cell. [..] Read more

Abstract: Prevailing modes of the manufacture of modern energy-harvesting systems and other electronics based on silicon fail to meet the requirements of the steps involved in low-cost fabrication. Rapid and low-cost roll-to-roll manufacture – the future of commercialization for flexible and printed electronics – requires flexible and low-cost substrates such as polyethylene terephthalate, polyethylene naphthalate and, more recently, green materials such as nano-paper.

Abstract: Laser surface processing is an established method to introduce surface functionalities on solid surfaces with the required throughputs for a commercial process. Fabrication of laser induced surface structures in an effective matter is done by laser interaction studies, which reveal the best processing parameters (laser wavelength, fluence, repetition, together with the processing speed and environment).

Abstract: Solid solutions La0.5Ca0.5Mn1-xFexO3 synthesized by the method of polymer-salt compositions at a temperature of 900° C with the perovskite structure were tested in the methane oxidation reaction. It was shown that at 600° C, complete conversion of methane occurs for all compositions, however, the nature of the dependence of the degree of conversion for lower temperatures is not linear and depends on the chemical composition.

Abstract: Li-rich oxides of different phase compositions xLi2MnO3·(1-x)LiMO2 are synthesized by coprecipitation of mixed transition metal carbonates followed by solid-state reaction with lithium hydroxide. X-ray powder diffraction, scanning electron microscopy, and magnetic studies are used to characterize the pristine structure of the oxides with different compositions. [..] Read more

Abstract: Lithium-rich oxides with different compositions are synthesized by coprecipitation method and tested as cathode materials for lithium-ion batteries (LIBs). The paper presents research into the degradation processes: capacity and voltage fade during cycling life. [..] Read more

Abstract: The recent progress in the field of immunoassays has been driven by introduction of various kinds of nanomaterials. In particular, photon-upconversion nanoparticles (UCNPs) proved to be excellent immunoassay labels due to their ability to emit light of shorter wavelengths under near-infrared excitation (anti-Stokes emission), which prevents autofluorescence, minimizes light scattering, and thus reduces the optical background interference.

Abstract: Photon-upconversion nanoparticles (UCNPs) are lanthanide-doped nanocrystals that can be excited by near-infrared light and emit photon-upconversion luminescence of shorter wavelengths. Advantages of UCNPs include near-infrared excitation, multiple and narrow emission bands, negligible autofluorescence and high stability, which make UCNPs ideal luminescence label for use in biological and chemical assays.

Abstract: In this paper photoluminescence properties of aqueous suspensions of carbon nanoparticles (nanodiamonds, carbon dots and complexes on their basis) with different ratio of surface carbon in sp3- and sp2-hybridizations were studied by methods of Raman, fluorescence and IR absorption spectroscopy. It was found that intensity of photoluminescence correlates with amount of carbon in non-diamond phase on the surface of nanoparticles. [..] Read more

Abstract: Zinc oxide nanoparticles (ZnO NP) have shown great potential as a novel antibacterial material at a time when resistance towards conventional antibiotics is becoming more prevalent. We report bacteria inactivation by ZnO NP with novel hedgehog-like morphology using model gram-negative (E. [..] Read more

Abstract: Copper oxide nanoparticles (CuO NPs) have a widespread use in industry, chemistry, in production of electronic devices and as an antimicrobial agent. Although copper is an important biogenic element, CuO NPs are toxic with the ability to induce oxidative stress, apoptosis, cell cycle arrest or DNA damage. [..] Read more

Abstract: We introduce a straightforward mathematical method for improving the AFM image resolution, applied to image analysis of helicene-based macrocycles adsorbed on HOPG. The method reveals structural details from insufficiently resolved AFM images and attributes them to internal structure and ordering of the macrocycles. [..] Read more

Abstract: For investigation of the influence of temperature of nanopowder calcination on adsorption properties of zirconiananoparticles, the pH-metry method was used.

Abstract: Scanning electron microscopy was used to determine physical properties of microwave plasma synthesized graphene nanosheets such as size and shape under various electron beam parameters (accelerating voltage, electron beam current, working distance). The stability and amount of defects of graphene nanosheets structure was investigated in dependence on these parameters and the results were compared to data obtained by TEM and Dynamic light scattering (DLS).
