  • Charge transport and gaz sensing peculiarities of nanocrystalline and amorphous tellurium films 
    TSIULYANU, Dumitru; CIOBANU, Marina; MOCREAC, Olga; AFANASIEV, Andrei (Tehnica UTM, 2020)
    Nanocrystalline and amorphous tellurium thin films have been prepared and their both DC and AC electrical conductivity was investigated to receive the information concerning mechanisms of charge transport at different ...
  • Gas sensitive films based on Te-SnO2 nanocomposite on flexible substrate 
    TSIULYANU, Dumitru; MOCREAC, Olga; AFANASIEV, Andrei; MONAICO, Eduard (Technical University of Moldova, 2022)
    Flexible films based on novel Te-SnO2 nanocomposites were fabricated for detection of toxic gases at room temperature. The Te-SnO2 nanocomposites were obtained via solvohermal recrystallization of pure crystalline tellurium ...
  • Senzor de gaze toxice 
    ŢIULEANU, Dumitru; CIOBANU, Marina; MONAICO, Eduard; AFANASIEV, Andrei (Agentia de Stat pentru Proprietatea Intelectuala a Republicii Moldova (AGEPI), 2021-04-30)
    Invenţia se referă la dispozitive sensibile la gaze, în particular la senzori de gaze toxice din material calcogenic pe bază de telur sau aliajele lui, şi poate fi utilizată la detectarea rapidă a gazelor toxice în ...
  • A simple fabrication route of tellurium nanocomposites via solvothermal recrystallization in nitric acid 
    AFANASIEV, Andrei; MOCREAC, Olga; TSIULYANU, Dumitru (Trans Tech Publications Ltd, 2025)
    Nanocomposites of tellurium and sodium nitrate were synthesized via a simple thermal dissolution of polycrystalline tellurium powder in nitric acid, followed by tellurium reduction in the presence of sodium dithionite ...
