Green-emitting strontium thiogallate doped with Eu(SrGaS:Eu)thin film phosphors were prepared by the multi- source deposition technique using two electron beam evaporation sources and a thermal annealing at higher than 800℃ or both low temperature annealing and laser annealing using krF excimer laser in atmosphere of 1% HS diluted with Ar. The film annealed at 850℃ showed a luminance of around 2.7×10cd/m under excitation with 5kV and 60μA/cm. Moreover,In this study,preparation of green-emitting SrGaS:Eu thin film phosphors by thermal annealing at tempera- tures lower than 600° was also tried with an assist with a laser annealing technique with 248nm due to krF excimer laser. It was shown that the film annealed at 500℃ consisted of SrGS single phase and showed about 2000cd/m under excita- tion with 4 kV,60μA/*** results indicate that the process of the laser annealing is useful for the realization of FEDs with high performance.

＜正＞In order to obtain the basic knowledge needed for an efficient flat membrane filtration system for the wastewater from chemical-mechanical polishing （CMP）, we have investigated the formation mechanisms of silica gel from a colloidal silica slurry using a membrane filtration system. And besides, for recycling the wet silica gel as a fine silica powder, the experimentally formed wet silica gel was heat-dried and also freeze -dried, and then the micromorphology, specific surface area and pore size distribution of the obtained powders were investigated. The basic mechanisms of slurry filtration, including the effects of vacuum pressure and slurry volume, can be explained by Darcy’s Law. The freeze-dried gel sample was transformed to a fine powder, however the heat-dried one became a sintered solid. Our results indicate that, in the plant, the recovered wet silica gel can be recycled as a fine silica powder by a freeze-dry treatment. The specific surface area and the pore size distribution of the powders were significantly affected by the slurry pH.

Background:We investigated potential disparities in health-related quality of life,particularly concerning urinary function,between patients with preserved and those with impaired sexual function after robot-assisted radical prostatectomy(RARP).Materials and methods:BetweenDecember 2012 and April 2020,704men underwent RARP in our *** study included 155 patients with a preoperative 5-item International Index of Erectile Function(IIEF-5)of≥12 points and an assessable IIEF-5 at 12 months ***-related quality of life was assessed using the 8-item Short-Form Health Survey and Expanded Prostate Cancer Index Composite(EPIC)preoperatively and at 3,6,and 12months postoperatively.A logistic regression analysis andWilcoxon rank sum tests were ***:Patients were grouped according to the median IIEF-5 score 12 months after surgery:those with preserved sexual function(n=71)and those with impaired sexual function(n=84).The mental component summary of the 8-item Short-Form Health Survey was better in the group with preserved sexual function at 6 months postoperatively than in the group with impaired sexual function(p<0.01).In the EPIC,the group with preserved sexual function performed better not only in the sexual domain but also in the urinary domain at all time points comparedwith the groupwith impaired sexual function(p<0.01).In the comparison of the urinary subdomains of the EPIC,there were no significant differences in urinary function or incontinence,but there were significant differences in urinary distress and irritative/obstructive scores(p<0.01).Conclusions:Patients with preserved postoperative sexual function after RARP showed better urinary function than those with impaired sexual ***,preserved sexual function is closely associated with urinary function.
