  • Fabrication and characterization of flexible composite material based on Aerographite/InP micro-nanostructures 
    PLESCO, Irina; STROBEL, Julian; SCHÜTT, Fabian; GORCEAC, Leonid; CINIC, Boris; HIMCINSCHI, Cameliu; MISHRA, Yogendra Kumar; KIENLE, Lorenz; ADELUNG, Rainer; TIGINYANU, Ion (Technical University of Moldova, 2017)
    The goal of this work is to extend the class of flexible hybrid nanomaterials based on aerographite scaffolds. For this purpose, we developed the technological conditions for the deposition of InP:Zn micro- and nanostructures ...
  • Fabrication of Porous Nanostructures by Design 
    MONAICO, Eduard; MONAICO, Elena; URSAKI, Veaceslav; TIGINYANU, Ion (Technical University of Moldova, 2017)
    We report on the application of special design of masks for the purpose of electrochemical etching of InP single crystals which enables one to change in a controlled fashion the direction of propagation of pores, including ...
  • Gas sensors based on optical fiber coated with nanocrystalline TiO2 and nanofibrous ZnO 
    GHIMPU, Lidia; PLESCO, Irina; URSACHI, Veaceslav; TIGINYANU, Ion; ZARRELLI, Mauro; ZOTTI, Aldobeneddetto; BORRIELLO, Anna (Technical University of Moldova, 2017)
    The paper is divided into two main sections: first, we report on magnetron sputtering of zinc oxide and titanium dioxide; second, the results of the investigation of the morphology and sensing characteristics of the optical ...
  • Hydrogen detection by individual Pd-modified ZnO nanowire 
    LUPAN, Oleg; PAUPORTÉ, Thierry; POSTICA, Vasile; VIANA, Bruno; ADELUNG, Rainer; CHOW, Lee; TIGINYANU, Ion (Technical University of Moldova, 2017)
    In this work an individual Pd-modified ZnO nanowire (Pd/ZnO NW) was integrated into a nanosensor device using focused ion beam (FIB)/scanning electron microscopy (SEM) system. The Pd/ZnO arrays were synthesized by ...
  • Influence of Metal Deposition on Electrochemical Impedance Spectra of Porous GaP and GaN Semiconductors 
    ANICAI, Liana; GOLGOVICI, Florentina; MONAICO, Eduard; URSAKI, Veaceslav; PRODANA, Mariana; ENACHESCU, Marius; TIGINYANU, Ion (Technical University of Moldova, 2017)
    A comparative analysis of electrochemical impedance spectroscopy (EIS) characterization is performed in porous GaN and GaP templates with and without metal nanostructured layers deposited by pulsed electroplating. The ...
  • Pulsed Electroplating of Metal Nanoparticles form DODUCO Electrolytes 
    MONAICO, Eduard; BRINCOVEANU, Oana; MESTERCA, Raluca; URSAKI, Veaceslav; PRODANA, Mariana; ENACHESCU, Marius; TIGINYANU, Ion (Technical University of Moldova, 2017)
    The mechanisms of Au deposition on InP porous substrates during a pulsed electroplating process are investigated by means of Topography imaging and Current Mapping measurements. The obtained results confirm the formation ...
