    Interpretarea psihologică a culorilor nu este un limbaj 100% precis. Însă alături de alţi factori asociaţi comunicării vizuale, culoarea poate fi utilizată pentru a forma mesaje vizuale clare.
  • PERCIUN, Andrei (Institutul de Istorie, 2019)
    The difficulty to objectify a picture comes from the poor identification of the image with its material support. Based on this material, it creates an object, which is often not in the ǀieǁer’s surroundings. Thus, the image ...
  • SHISHIYANU, Sergiu T.; SHISHIYANU, Teodor S.; LUPAN, Oleg I. (ELSEVIER, 2005)
    NO2 gas sensor was fabricated by successive ionic layer adsorption and reaction (SILAR) technique and rapid photothermal processing (RPP) of the Sn-doped ZnO film. The experimental results shows that tin doping of zinc ...

    This study reports on a new type of moisture protected gas sensor, which is capable to solve this problem. Sensitive nano-materials of CuO/Cu2O/ZnO:Fe heterostructures are grown and subsequently coated with an ultrathin ...
  • LUPAN, Oleg; SCHÜTT, Fabian; POSTICA, Vasile; SMAZNA, Daria; MISHRA, Yogendra Kumar; ADELUNG, Rainer (Springer Nature Limited, 2017)
    In this work, the influence of carbon nanotube (CNT) hybridization on ultraviolet (UV) and gas sensing properties of individual and networked ZnO nanowires (NWs) is investigated in detail. The CNT concentration was varied ...
  • TSIULYANU, D.; MARIAN, S.; MIRON, V.; LIESS, H.-D. (IEEE, 2001)
    The effect of propylamine (C/sub 3/H/sub 7/NH/sub 2/) on electrical conductivity of tellurium based thin films has been investigated. It is shown that the absorption of the propylamine vapor leads to reversible increase ...
  • TSIULYANU, D.; STRATAN, I.; TSIULYANU, A.; EISELE, I. (IEEE, 2006)
    Effect of O2 , N2 and H2O to electrical behaviour of tellurium-based films has been studied at temperatures between 20 degC and 70 degC. The increase of oxygen partial pressure in NO2 + O2 carrier gas results in a nearly ...
  • TSIULYANU, D.; MARIAN, S.; LIESS, H.-D. (Elsevier, 2002)
    The effect of propylamine (C3H7NH2) and carbon oxide on electrical conductivity of tellurium based thin films has been investigated. It is shown that the absorption of the propylamine vapor leads to reversible increase of ...
