“…2 The decline of pH during the fermentation process was an essential condition for the accumulation of PL. To enhance the productivity, a twostep cultivation was investigated and 4-5 g / L P L could be produced for 8 or 9 days.4 P L showed antimicrobial activity against Gram-positive and -negative bacteria a t concentrations of [1][2][3][4][5][6][7][8] ~g / m L .~ The activity of the antiphage of P L was also reported. 6 As a modification of poly (amino acid), hydrogel preparation by y irradiation was It was found that poly ( y-glutamic acid) (PGA) , which is another poly (amino acid) produced by Bacillus strains,'-" converted to a transparent hydrogel with high water sorption ability on y irradiation.…”

SYNOPSISPoly(c-lysine) (PL) hydrogels have been prepared by means of y irradiation of P L produced by Streptomyces albulus in aqueous solutions. When the dosage of y irradiation was 70 kGy or more and the concentration of P L in water was 1-7 wt %, transparent hydrogels (opaque hydrogels for 1-3 wt % P L concentration) could be produced. In the case of 70 kGy of y irradiation and 5 wt % P L concentration, the specific water content (wt of absorbed water/wt of dry hydrogel) of the PL hydrogel was approximately 160. Specific water contents of P L hydrogels decreased markedly with an increase in the dosage of y irradiation. The specific water contents were increased with an increase in P L concentration in the irradiated solution. This result indicates the presence of a radical scavenger in the P L solution. Swelling equilibria of P L hydrogels were measured in water or in aqueous solutions of various pHs or concentrations of NaC1, Na2S04, and CaC1,. Under acid conditions, the P L hydrogel swelled due to the ionic repulsion of the protonated amino groups in the P L molecules. The degree of deswelling in electrolyte solution was smaller than that of other ionic hydrogels [poly(y-glutamic acid), poly(acry1ic acid) etc.]. In addition, the enzymatic degradations of P L hydrogel were studied a t 40°C and pH 7.0 in an aqueous solution of the neutral protease [Protease A (Arnano)] produced from Aspergillus oryzae. The rate of enzymatic degradation of the respective P L hydrogels was much faster than the rate of simple hydrolytic degradation. The rate of enzymatic degradation decreased with the increase in y-irradiation dose during preparation of the P L hydrogel. 0 1995 John Wiley & Sons, Inc.

“…This means that the quality of the color filter has a decisive effect on the LCD's color reproduction. Thus, flat panel LCD displays are now without doubt the way of the future and their rapid development in recent years has made them one of the most important fields in high technology today [1]. The reproduction of color imagery in TFT displays is achieved through the use of color filters in conjunction with a backlighting system.…”

A new triangular-shape designed tool as a cathode in microelectromechanical etching process is a precision nanoscale production of a reclamation system of Indium tin oxide (ITO) thin-films defects removal from optoelectronic flat panel displays’ color filter surface is demonstrated in the current study. Through the ultra-precise removal of the thin-film nanostructure, the optoelectronic semiconductor industry can effectively reclaim defective products, reducing production costs. In the current experiment, a large size triangular shape cathode is accompanied by a small gap-width between the cathode and the workpiece takes less time for the same amount of ITO removal. A higher feed rate of displays’ color filter or a small end radius of the cathode combined with enough electric power produces fast machining. Pulsed direct current can improve the effect of dregs discharge and is advantageous in association with a fast workpiece feed rate. However, it raises the current rating. A large flow rate of the electrolyte corresponds to a higher removal rate for the ITO nanostructure. The electrochemical etching just needs a short time to make the ITO remove removal easy and clean.

Although the low yield rate of ITO thin-film during the production of semiconductor techniques is easily seen. Current work presents a new modus of electrochemical machining using a design rolling tool as electrodes constructs a precision recycle process offering faster performance in removing the color filter surface’s ITO thin-film. Through establishing an ultra-precise recycling process to remove the thin-film microstructure, this helps the semiconductor optoelectronic industry to reduce both production costs and pollution. The design features of the removal processes for a thin-film and the tool design of rolling electrodes are of major interest. Higher electrical current is not required when an effective feeding electrodes is used to reduce the response area. In the current experiment, the author utilizes a 5th Generation TFT-LCD. The design electrodes (rolling tool) are used with continuous and pulsed direct current in the electrochemical machining experiment. A displays’ color filter with a fast feed rate is combined with enough electric power to provide highly effective removal. High rotational speed of the rolling tool and high flow velocity of the electrolyte elevates the discharge mobility and improves the removal effect. A larger diameter of the fictitious rotation circle of the cathode and a small end radius of the cathode provide better removal effect. A precision recycling process is presented using an effective rolling tool in the electrochemical machining. It only needs a short period of time to remove the ITO thin-film easily and cleanly.
