  • Synthesis of Cu3N and Cu3N-Cu2O multicomponent mesocrystals: Non-classical crystallization and nanoscale Kirkendall effect

    Nanoscale, 2021
    By combining the non-classical crystallization with the nanoscale Kirkendall effect, Cu3N mesocrystals are synthesized by a surfactant-assisted method and transformed into heterostructured Cu3N–Cu2O mesocrystals and Cu2O nanocages.

    ACS Energy Letters, 2020
    Direct conversion of methane to methanol has been a long-sought objective. Partial oxidation by thermal catalysis is possible but suffers from a rapid loss in methanol selectivity with increasing m...
  • Single Nanoparticle Magnetic Spin Memristor
    Hammam Al-Bustami, Guy Koplovitz, Darinka Primc, Shira Yochelis, Eyal Capua, et al.
    Small, 2018
    There is an increasing demand for the development of a simple Si-based universal memory device at the nanoscale that operates at high frequencies. Spin-electronics (spintronics) can, in principle, increase the efficiency of devices and allow them to operate at high frequencies. A primary challenge for reducing the dimensions of spintronic devices is the requirement for high spin currents. To overcome this problem, a new approach is presented that uses helical chiral molecules exhibiting spin-selective electron transport, which is called the chiral-induced spin selectivity (CISS) effect. Using the CISS effect, the active memory device is miniaturized for the first time from the micrometer scale to 30 nm in size, and this device presents memristor-like nonlinear logic operation at low voltages under ambient conditions and room temperature. A single nanoparticle, along with Au contacts and chiral molecules, is sufficient to function as a memory device. A single ferromagnetic nanoplatelet is used as a fixed hard magnet combined with Au contacts in which the gold contacts act as soft magnets due to the adsorbed chiral molecules.
  • Synthesis and Formation Mechanism of Multicomponent Sb-Nb:TiO2 Mesocrystals
    Darinka Primc, Markus Niederberger
    Chemistry of Materials, 2017
    The synthesis of multicomponent mesocrystals represents an emerging strategy for obtaining nanomaterials with unique functionalities as a result of combining porosity and crystallographic order. This study presents the first synthesis of multicomponent Sb–Nb:TiO2 mesocrystals (Sb-mesoNb/TO) by using a microwave-assisted nonaqueous sol–gel method. Structural and chemical analyses, carried out using various transmission electron microscopy techniques, show that Sb-mesoNb/TO are 25–35 nm in size and composed of crystallographically aligned Nb:TiO2 subunits, embedded in a porous amorphous Sb-rich scaffold (Sb-scaffold). On the basis of the characterization of the intermediate products, the formation mechanism is proposed, involving a kinetically controlled particle-based assembly process. The latter is triggered by the occurrence of the Sb-scaffold in the early reaction stages, acting as a support for heterogeneous nucleation of Nb:TiO2 subunits. Subsequently, Nb:TiO2 subunits grow and assemble in a mutual cr...
  • Magnetic Nanoplatelet-Based Spin Memory Device Operating at Ambient Temperatures
    Guy Koplovitz, Darinka Primc, Oren Ben Dor, Shira Yochelis, Dvir Rotem, et al.
    Advanced Materials, 2017
    There is an increasing demand for realizing a simple Si based universal memory device working at ambient temperatures. In principle, nonvolatile magnetic memory can operate at low power consumption and high frequencies. However, in order to compete with existing memory technology, size reduction and simplification of the used material systems are essential. In this work, the chiral‐induced spin selectivity effect is used along with 30–50 nm ferromagnetic nanoplatelets in order to realize a simple magnetic memory device. The vertical memory is Si compatible, easy to fabricate, and in principle can be scaled down to a single nanoparticle size. Results show clear dual magnetization behavior with threefold enhancement between the one and zero states. The magnetization of the device is accompanied with large avalanche like noise that is ascribed to the redistribution of current densities due to spin accumulation inducing coupling effects between the different nanoplatelets.
  • Doping of TiO2 as a tool to optimize the water splitting efficiencies of titania-hematite photoanodes
    Darinka Primc, Mario Bärtsch, Davide Barreca, Giorgio Carraro, Chiara Maccato, et al.
    Sustainable Energy and Fuels, 2017
    Doping of TiO2 enables tailoring of the phase composition, microstructure and topography of titania–hematite photoanodes during annealing, resulting in remarkable photocurrents.
  • Chemical Substitution - Alignment of the Surface Potentials for Efficient Charge Transport in Nanocrystalline TiO2 Photocatalysts
    Darinka Primc, Guobo Zeng, Richard Leute, Michael Walter, Leonhard Mayrhofer, et al.
    Chemistry of Materials, 2016
    Anatase TiO2 is among the most studied photocatalytic materials for solar energy conversion and environmental cleanup. However, its poor visible light absorption and high facet-dependent performance limits its utilization. In this study chemical substitution (doping) of TiO2 nanoparticles with metal ions (Sb, Cr, or Sb/Nb and Cr/Nb) is presented as an alternative strategy to address both issues simultaneously. Highly crystalline doped and codoped TiO2 nanoparticles were successfully synthesized by a microwave-assisted nonaqueous sol–gel synthesis. The structural and compositional analysis done by X-ray diffraction (XRD), high resolution transmission electron microscopy (HRTEM), and X-ray photoelectron spectroscopy (XPS) showed that depending on the doping applied, variations in particles size and morphology were observed. Doped and codoped samples showed improved absorption in the visible range and in comparison to the undoped TiO2 displayed improved photocatalytic (PC) activity. The variations of the PC ...
  • Size-Dependent Luminescence in HfO2 Nanocrystals: Toward White Emission from Intrinsic Surface Defects
    Irene Villa, Anna Vedda, Mauro Fasoli, Roberto Lorenzi, Niklaus Kränzlin, et al.
    Chemistry of Materials, 2016
    Defect engineering operated on metal oxides by chemical and structural modifications may strongly affect properties suitable for various applications such as photoelectrochemical behavior, charge transport, and luminescence. In this work, we report the tunable optical features observed in undoped monoclinic HfO2 nanocrystals and their dependence on the structural properties of the material at the nanoscale. Transmission electron microscopy together with X-ray diffraction and surface area measurements were used to determine the fine structural modifications, in terms of crystal growth and coalescence of crystalline domains, occurring during a calcination process in the temperature range from 400 to 1000 °C. The fit of the broad optical emission into spectral components, together with time-resolved photoluminescence, allowed us to identify the dual nature of the emission at 2.5 eV, where an ultrafast defect-related intrinsic luminescence (with a decay time of a few nanoseconds) overlaps with a slower emissi...

  • Multiscale anode materials in lithium ion batteries by combining micro-with nanoparticles: Design of mesoporous TiO2 microfibers@nitrogen doped carbon composites
    Wei Cheng, Felix Rechberger, Darinka Primc, Markus Niederberger
    Nanoscale, 2015
    TiO2 has been considered as a promising anode material for lithium ion batteries. However, its poor rate capability originating from the intrinsically low lithium ion diffusivity and its poor electronic conductivity hampers putting such an application into practice. Both issues can be addressed by nanostructure engineering and conductive surface coating. Herein, we report a template-assisted synthesis of micron sized TiO2 fibers consisting of a mesoporous network of anatase nanoparticles of about 7.5 nm and coated by N doped carbon. In a first step, an amorphous layer of TiO2 was deposited on cobalt silicate nanobelts and subsequently transformed into crystalline anatase nanoparticles by hydrothermal treatment. The N doped carbon coating was realized by in situ polymerization of dopamine on the crystalline TiO2 followed by annealing under N2. After removal of the template, we obtained the final mesoporous TiO2 fibers@N doped carbon composite. Electrochemical tests revealed that the composite electrode exhibited excellent electrochemical properties in terms of specific capacity, rate performance and long term stability.
