• Conference Proceeding: Synthesis and characterization of indium tin oxide and cerium dioxide thin films by sol-gel method

  A. Ciuciumis, I. Cernica
  [show abstract] [hide abstract]
  ABSTRACT: The paper presents indium tin oxide and cerium dioxide thin films obtained by sol-gel method and deposited on the different wood substrates. Films deposition was performed by immersion of the substrates into coating solution and flow-coating process. Investigation of the surface chemistry and morphology of the wood substrates before and after deposition were obtained by means of atomic force microscopy and optical microscopy. The sol-gel deposit on the wood substrates lowered the rates of water and water vapour sorption (absorption and/or adsorption).

  ABSTRACT: The use of microfluidic devices in biomedical research creates clinically useful technologies and devices (for biochemical reaction chambers, and physical particle separation), or in IC chip cooling applications has significant advantages. In the first case, because the fluid volumes within these microchannels are very small, usually several nanoliters, the amount of reagents and analytes used is quite small. In the second case, they present a negligible thermal resistance, due to direct contact with the chip dissipation surface. This paper presents some new technological methods used to prepare by surface microfabrication microchannels and other microfluidic elements, like chambers onto different substrates.

• Conference Proceeding: Honeycomb textured front surface of monocrystalline silicon and borosilicate glass substrates

  E. Manea, E. Budianu, M. Purica, I. Cernica, A. Ciuciumis, F. Babarada
  [show abstract] [hide abstract]
  ABSTRACT: We present the results of an experimental study regarding the increase of the silicon solar cells efficiency by texturing the front surface and the fabrication of microcells on borosilicate glass substrate using silicon micromachining technologies. A `honeycomb' textured front surface has been obtained using a photolithography process to generate patterns (disc hole) on the top surface followed by isotropic etching

• Conference Proceeding: Optimized methods for piezoelectric powders synthesis in microsensors applications

  A. Ciuciumis, A. Folea, I. Cernica
  [show abstract] [hide abstract]
  ABSTRACT: This paper presents the effect of heating rate on the sintering behavior and the influence amounts of dopants on the stabilization powders. Different types of powders (doped with La₂O₃) were sintered at 1100°C for 2h with a wide range of heating rate. Investigations of phase compositions, densification and microstructure were performed.

• Conference Proceeding: Unconventional processing technique for ceramic materials

  A. Ciuciumis, A. Folea, D. Radu
  [show abstract] [hide abstract]
  ABSTRACT: The paper presents the experiments developed in order to establish an improved processing technique for ceramic materials, characterized by low temperature and short heating time. The aims are the enhancement of electrical and mechanical properties, when compared to the ceramics prepared by conventional sintering process. The advantages of the new technique based on microwaves were evidenced.
