Carbon quantum dots (CDs) are a new class of fluorescent carbonaceous nanomaterials that were casually discovered in 2004. Since then, they have become object great interest the scientific community because their peculiar optical properties (e.g., size-dependent and excitation wavelength-dependent fluorescence), which make them very similar to well-known semiconductor suitable for application p...

Objectives: Despite the improvements in early-term outcomes of kidney transplantation, late-term graft failure still remained as a critical problem. De novo donor specific antibodies (DSA) developing against direct human leukocyte antigens (HLA) are significant risk factors for shortened survival previously non-sensitized cases. The purpose this study is to evaluate clinical de DSA development ...

Nanocrystalline titanium (iv) oxide paste has been deposited on Fluorine doped tin oxide glass substrate by the blade method. The deposited film was subjected to thermal treatment to obtain an electrode foe a photo-electrochemical cell. The electrode was sensitized with prophyrin dye which was a local dye extracted from carica papaya leaves. Avaspec 2.1 spectrophotometer was used to obtain the ...

two organic compounds (sc-23=(e)-2-cyano-3-(2,3-dimethoxyphenyl) acrylic acid and sc-25=(e)-2-cyano-3-(2,5-dimethoxyphenyl) acrylic acid) involving methoxy groups as the electron donor and cyanoacrylic acid group as the electron acceptor have been investigated for dye sensitized solar cells. they shows a short-circuit current density (jsc) of 2.08 and 1.81 ma cm-2, an open circuit voltage (voc)...

a  commercial  ti-nanoxide  was  deposited  on  in-doped  sno2 (ito) polymer  substrates by  tape casting  technique with different thicknesses  (7,  14  and  36μm)  to  be  used  as  photoelectrode  in flexible  dye-sensitized  solar  cells  (dsscs).  ruthenium  dye  was adsorbed on each tio2 film for 24 h. the resulting photoelectrodes were used to form flexible dsscs in combination with elec...

Co-sensitized solar cells have gained more attention due to the ability of energy conversion process by absorbing photons from wide range spectrum including visible and near-infrared region. TiO2 electrodes were co-sensitized with PbS/CdS core-shell quantum dots N719 dye. PbS/CdS/N719 dye-sensitized fabricated poly(ethylene oxide) based solid polymer electrolyte consisting iodide/triiodide redo...

Effects of intra-central amygdala administration of L-arginine, a nitric oxide precursor, and NG-nitro-L-arginine methyl-ester (L NAME), a nitric oxide synthase inhibitor, on the morphine-induced sensitization and also on the expression of morphine-induced place conditioning in rats were studied. Subcutaneous (s.c.) administration of morphine (2.5, 5 and 7.5 mg/kg) induced place conditioning. R...
