Based on the polymer and plastic analogy, the annual market for products that carry nano-components, including all computer chips, half of pharmaceuticals and half of chemical catalysts, will reach $1 trillion by 2015.
      
The gas-phase photocatalytic oxidation of aniline on a new kind of porous nano-TiO2 composite films is investigated.
      
The novel composite mainly consists of nano-hydroxyapatite (n-HA), which is the main inorganic content in natural bone tissue for the PLA.
      
Thus, it is evident that although large specific surface area is important for nano-NaH to be used as a catalyst component, high surface energy with surface defects seems to be more important.
      
Fe3O4 magnetic nano-particles were prepared by a co-precipitation method and were modified using oleic acid.

A colorimetric method for the determination of antimony in the range 0.1 to 3.0μg per milliliter blood is described. The time needed for the destruction of organic matter is shortened to 8—12 minutes. The proposed method is as follows: Accurately transfer 1 ml of blood sample to a hard glass test tube (25×150 mm.), to which 1 ml of conc. HNO_3 is then added. Heat gently with a small flame till the solution changes to amber color. Add 0.5 ml conc. H_2SO_4 and heat again carefully until dense white fume is evolved....

Heat gently with a small flame till the solution changes to amber color. Add 0.5 ml conc. H_2SO_4 and heat again carefully until dense white fume is evolved. If the solution is not clear, add a few more drops of HNO_3 and heat repeatedly till a clear colorless solution is obtained. Cool, add 1 ml NaCl solution and 0.5 ml NaNO_2 solution, shake for 2 minutes, then add 1 ml of urea solution. Transfer the mixture to a separatory funnel containing 10.0 ml benzene. Wash the test tube with three portions (5 ml) of distilled water, add 10 drops of malachite green reagent solution and shake the mixture immediately for 5 minutes. Separate the benzene layer in a centrifuge tube and centrifuge 3 minutes to separate the suspended droplets of water. Transfer the benzene solution into a 10 cm cell and measure the extinction with an Ilford 607 filter, using benzene as blank.

1. α-amylase, saccharifying enzyme, maltase and limit dextrinase have been tested in this research work. According to the results of more than 10 experiments, the following conclusions may be made: (a)Although Asp. oryzae, No. 7 possesses greatest liquifying power, the aleohol yield by using this mold as saccharifying agent is lowest among all the molds tested. It is obvious that, there is no direct relationship between α-amylase value and alcohol yield. (b) Maltase value of Asp. oryzae No.7 is much lower than...

1. α-amylase, saccharifying enzyme, maltase and limit dextrinase have been tested in this research work. According to the results of more than 10 experiments, the following conclusions may be made: (a)Although Asp. oryzae, No. 7 possesses greatest liquifying power, the aleohol yield by using this mold as saccharifying agent is lowest among all the molds tested. It is obvious that, there is no direct relationship between α-amylase value and alcohol yield. (b) Maltase value of Asp. oryzae No.7 is much lower than that of other molds, for example, mal-tase value of Asp. niger, NRRL 330 is 7.24,while that of Asp. oryzae, No.7 is only 0.06. The alcohol yield of the latter is about 20% less than that of the former. in other words, the higher the maltase value, the higher the alcohol yield. This conclusion is obviously in agreement with previous investiga- tions. When the saccharifying value is high, the limit dextrinase value is also high. But the inter-relationship between limit dextrinase and alcohol yield requires further investigation. 2. Concerning the selection of mold suitable for submerged culture, Asp. niger, No. 2 is the best one, according to the results of 1st and 2nd period of our experiments; while Asp. niger, NRRL 330 isnext to Asp. niger No. 2. 3. Concerning the selection of culture medium, 3 kinds of media: (1) potato powder 8%, NaNO_2 0.3%, HCl (37%) 0.1%; (2) maize 5%, rice bran 1%, wheat bran 1.5%; (3) distillers solubles 3.5% maize 5%,(pH 5.0) have been adopted. Among these media, No. 2 is the best, No. 1 is next and No.3 is not suitable for Asp. niger, No. 2.

酒精的用途很大,无论在国防工业上、医药卫生上以及其他有关工业上都需要大量酒精。另一方面,我国土法制酒,淀粉利用率很低,因此,浪费大量粮食。最近中央倡议“白酒酒精化”,就是用酒精配制白酒,因为新法造酒的淀粉利用率较高,可以节约很多粮食。此后酒精工业对国民经济的关系更大,我们科学工作者的任务也更繁重。

(1) According to Griess reaction, diazonium-salts formed from aromatic amines such as sulfonamides etc., react with NaNO_2 in acid medium and may be coupled with α-naphthylamine or diphenylamine to produce red colored compounds. In presence of excess NaNO_2, these red colored compounds will further Change to brownish yellow. For diazotization titration, diphenylamine is used as a good internal indicator. (2) Internal indicator may be used only in colorless solution and the end point is not sharp....

(1) According to Griess reaction, diazonium-salts formed from aromatic amines such as sulfonamides etc., react with NaNO_2 in acid medium and may be coupled with α-naphthylamine or diphenylamine to produce red colored compounds. In presence of excess NaNO_2, these red colored compounds will further Change to brownish yellow. For diazotization titration, diphenylamine is used as a good internal indicator. (2) Internal indicator may be used only in colorless solution and the end point is not sharp. (3) KBr should be added as a catalyst not only to accelerate the velocity of diazotization, but also to decrease the interaction between azo dyes and nitrous acid. (4) The indicator should be added after the addition of two-third of the amount of NaNO_2 required (the total quantities of NaNO_2 used amounted to 30ml) or before the addition of the last 5ml of NANO_2. The results thus obtained show practically no difference from these obtained by external indicator method.

(一)按Griess反应芳香族胺类的重氮化鹽,如对氨基苯磺醯胺类药物等,在酸性溶液中皆能与α-萘胺或二苯胺分别偶合成偶氮色素而显紅色,过多之亞硝酸可与氮色素再作用使紅色消失而呈棕黄色。二苯胺为較好的内指示剂。 (二)本法仅用于無色溶液。滴定至全量的三分之二以后加入指示剂較适宜。 (三)本反应宜在溴化鉀存在下进行。
