The optimal conditions to prepare the ultrafine silver powder were obtained by studying the effects of following factors, such as the selection of dispersant, the doses of dispersant and pH, on the dispersibility of silver powder under other constant conditions. The pure ultrafine silver powder with quasi-spherical shape and mean size of 1.15 m was synthesized under the optimal conditions of polyvinyl alcohol (PVA) as disperser, PVA/AgNO 3 mass ratio of 4:100 and pH 7 while maintaining other conditions exactly in the same circumstances, such as AgNO 3 concentration of 0.20 mol L −1 , ascorbic acid concentration of 0.15 mol L −1 and reaction temperature of 40 • C. The ultrafine silver powder was characterized by SEM and XRD. And a PVA dispersive mechanism for preparing highly dispersive ultrafine silver powder, proved by the ultraviolet spectra, is that PVA absorbed on the surface of silver particles by coordination bond preventing the silver particles from diffusion and aggregation. In addition, the steric effect may help to reduce aggregation.

Surface plasmon resonance sensor for femtomolar detection of testosterone with water-compatible macroporous molecularly imprinted film

The MIF was synthesized by photo copolymerization of monomers (methacrylic acid [MAA] and 2-hydroxyethyl methacrylate [HEMA]), cross-linker (ethylene glycol dimethacrylate, EGDMA), and polystyrene nanoparticles (PS NPs) in combination with template testosterone molecules. The PS NPs and template molecules were subsequently removed to form an MIF with macroporous structures and the specific recognition sites of testosterone. Incubation of artificial urine and human urine on the MIF and the non-imprinted film (NIF), respectively, indicated undetectable nonspecific adsorption. Accordingly, the MIF was applied on a surface plasmon resonance (SPR) sensor for the detection of testosterone in phosphate-buffered saline (PBS) and artificial urine with a limit of detection (LOD) down to 10(-15)g/ml. To the best of our ...

Effect of dispersibility of silver powders in conductive paste on microstructure of screen-printed front contacts and electrical performance of crystalline silicon solar cells

Two different dispersed degree silver powders were experimented. It is found that the dispersibility of the silver powders strongly affects the microstructure of thick film and electrical performance of solar cells and highly dispersed silver powders can form even compact thick film and exhibit higher open-circuit voltage (V oc ), short-circuit current (I sc ), shunt resistance (R sh ), maximum power (P max ), optimum operating voltage (V mp ), optimum operating current (I mp ), fill factor (FF) and photoelectric conversion efficiency (Eff) than seriously agglomerated silver powders under otherwise identical conditions.

Age at onset of recurrent major depression in Han Chinese women – A replication study

However, larger sample studies are needed to replicate and extend earlier findings. Methods: We re-examined the relationship between AAO and the clinical features of recurrent MD in Han Chinese women by analyzing the phase I (N¼ 1848), phase II (N¼ 4169) and total combined data (N¼ 6017) from the CONVERGE project. Linear, logistic, multiple linear and multinomial logistic regression models were used to determine the association of AAO with continuous, binary and categorical variables. Results: The effect size of the association between AAO and clinical features of MD was quite similar in the phase I and phase II samples. These results confirmed that MD patients with earlier AAO tended to suffer more severe, recurrent and chronic illness and cases of MD with earlier AAO showed increased neuroticism, greater family history and psychiatric comorbidity. In addition, we showed that earlier AAO of MD in Han Chinese women was associated with premenstrual symptoms, postnatal depression, a highly authoritarian or cold childhood parental rearing style and a reduced probability for having melancholia. Limitations: Data were collected retrospectively through interview and recall bias may have affected the results. Conclusions: MD with earlier AAO in Han Chinese women shows a distinct set of clinical features which are similar to those reported in Western populations.

The prevalence, clinical correlates and structure of phobic fears in Han Chinese women with recurrent major depression

We know little about the prevalence, clinical correlates, and structure of phobic fears in Chinese women with MD. We assessed 22 phobic fears in 6017 Han Chinese women with MD. We used exploratory factor analysis to examine the structure of these phobic fears. We examined the relationship between individual phobic fears and the severity of MD, neuroticism, comorbid panic disorder, generalized anxiety disorder and dysthymia using logistic regression models. The frequency of phobic fears ranged from 3.0% (eating in public) to 36.0% (snakes). Phobic fears were significantly associated with more severe MD, high neuroticism, and co-morbid panic disorder, generalized anxiety disorder and dysthymia. Our factor analysis suggested four underlying subgroups of phobic fears which differed in their clinical correlates, severity and patterns of comorbidity. Data were collected retrospectively through interview and recall bias may have affected the results. Phobic fears are correlated with comorbid MD and more severe MD. These phobic fears clearly subdivide into four subgroups that differ meaningfully from each other.

Epithelial sheet movement requires the cooperation of c-Jun and MAP3K1

Here we show that MAP3K1 associates with the cytoskeleton, activates Jun N-terminal kinase (JNK) and actin polymerization, and promotes the eyelid inferior epithelial cell elongation and epithelium protrusion. Following epithelium protrusion, c-Jun begins to express and acts to promote ERK phosphorylation and migration of the protruding epithelial cells. Homozygous deletion of either gene causes defective eyelid closure, but non-allelic non-complementation does not occur between Map3k1 and c-Jun and the double heterozygotes have normal eyelid closure. Results from this study suggest that MAP3K1 and c-Jun signal through distinct temporal-spatial pathways and that productive epithelium movement for eyelid closure requires the consecutive action of MAP3K1-dependent cytoskeleton reorganization followe...
