“…Copper and copper oxide nanoparticles have been used and investigated for a large number of applications, such as oxidation catalysts and as a component of solar cells [ 10 ], as well as being the major element of conductive inks and pastes used in inkjet-printed electronics [ 11 ]. Other applications are being developed due to their anti-microbial, anti-biotic and anti-fungal properties when incorporated in coatings, plastics and textiles and for biomedical applications [ 12 , 13 ].…”

BackgroundIncreasing numbers of individuals may be exposed to nanomaterials during pregnancy. The overarching goal of this investigation was to determine if prenatal inhalation exposure to copper nanoparticles (Cu NPs) has an effect on dams and offspring, including an analysis of inflammatory markers (Th1/Th2 cytokine profiles).MethodsPhysicochemical characterization of Cu NPs was performed. Pregnant and non-pregnant mice (C57Bl/6 J) were exposed to Cu NPs or laboratory air in the whole-body chamber for 4 hrs/day on gestation days (GD) 3–19 (3.5 mg/m3). Animals were euthanized on GD 19 (0 week) or 7 weeks later. Bronchoalveolar lavage (BAL) fluid was analyzed for total and differential cells. Cytokine/chemokine concentrations were determined in the BAL fluid and the plasma of dams/non-pregnant mice and pups. Cu content was determined in the lungs and the blood of dams/non-pregnant mice and pups, in the placentas as well as in the whole bodies of pups immediately after delivery. Lungs and placentas were evaluated for histopathological changes. Gene expression of the Th1/Th2 profiles were analyzed in spleens of pups.ResultsThe survival rate of 7 week old pups exposed to Cu NPs was significantly lower than control pups (73 vs. 97 %). The average litter size, male/female ratio, body weight and lenght at birth were not different between Cu NP-exposed and control mice. Both pregnant and non-pregnant mice exposed to Cu NPs had significant pulmonary inflammation with increased number of neutrophils in the BAL fluid compared to controls. Perivascular lymphoplasmacytic cuffing was found in the lungs of exposed mice and was more pronounced in the non-pregnant group. Similarly, levels of inflammatory cytokines/chemokines IL-12(p40), G-CSF, GM-CSF, KC, MCP-1, MIP-1α, MIP-1β, RANTES and TNF-α in BAL fluid were significantly higher in non-pregnant than pregnant exposed mice. Histopathology evaluation of placentas did not identify any pathological changes. No translocation of Cu into the placenta or the fetus was found by inductively coupled plasma-mass spectroscopy. Expression of several Th1/Th2 or other immune response genes in pups’ spleens were found to be significantly up- or down-regulated.ConclusionsPrenatal exposure to Cu NPs caused a profound pulmonary inflammation in dams and strong immunomodulatory effects in offspring. There was no clear polarization of genes expressed in pups’ spleens towards Th1 or Th2 type of response.Electronic supplementary materialThe online version of this article (doi:10.1186/s12989-015-0105-5) contains supplementary material, which is available to authorized users.

“…Inseok et al researched the enhancement of dye adsorption on TiO 2 surface through hydroxylation process for dye sensitized solar cells [12]. Generally, preparation of the working electrode was done by initially depositing TiO 2 paste on the substrate through doctor blade method [13] and then, sintered subsequently. Then working electrode is soaked in dye.…”

Dye-sensitized solar cell (DSSC) is a photoelectrochemical solar cell that is able to convert solar energy into electrical energy. Sintering of TiO2film and soaking process of TiO2film in the dye solution have significant effect on the DSSC performance. The TiO2film was sintered at varied temperature from 200 °C to 500 °C for 60 minutes. From the efficiency test, it is found that the optimum performance of DSSC was produced when the TiO2film was sintered at 450 °C. In addition, the dye soaking temperature was evaluated from the temperature 40 °C to 50 °C for 6 hours. The optimum soaking temperature was 50 °C of DSSC with maximum efficiency at 2,621 %.

Thin-film solar cells have the potential to substantially reduce the material cost of photovoltaic devices. However, to increase the amount of light absorbed in the thin active layer, light trapping is a critical concern in developing thin-film solar cells. In this study, we investigated the suitability of using localized surface plasmons of indium nanoparticles (In NPs) on TiO 2 space layers of various thicknesses to enhance the absorption of silicon (Si) thin-film solar cells. The experimental results demonstrated how the combined effects of the incident light plasmonics scattering, surface passivation, and antireflection of In NPs affect the photovoltaic performance of the TiO 2 space layer. The optical reflectance, dark current, photocurrent, and external quantum efficiency were measured and compared. Compared with bare-type Si thin-film solar cells, the proposed cells with In NPs on a 59.5-nm-thick TiO 2 space layer demonstrated a short-circuit current enhancement of 45.7% (from 2.56 to 3.73 mA) and a conversion efficiency enhancement of 36.2% (from 7.56 to 10.3%).
