(1)H2O:One day the science teacher asked the class,“What's the chemical formula for water?“A boy put up his hand, and the teacher said,”“Yes?”the boy said“HIJKLMNO”.“Are you trying to be funny?”asked the teacher angrily.“No, sir.”said the boy.“You said the formula ...
He suggested that the true acid really consisted of theoldoxideacidand “basic” water together. 他认为真正的酸实际上是由旧的氧化酸和“碱性”水一起组成的。 and that its basicity depended on the number ofreplaceablehydrogenatomsrather than the number of replaceable H2O molecules. 其碱性取决于可取...
a classical text on Chinese medicine, associates the ear with the brain and suggests that damage to the brain can result in damage to the ear [160]. Furthermore, the Chinese medical text ‘Suwen-Xuanji-original disease Formula’ contains records of acupuncture and magnetic...
2). Leaf area is one of the most reliable parameters reflecting the growth of the plant. A significant increase of leaf area under CM20 in comparison to OB suggests a direct positive correlation with the total biomass production of the plants, being maximal under the same amended treatment (...

Natural products (NPs) are a consistent source of antimicrobial metabolites and drug leads and are largely produced by soil-dwelling microorganisms10,11. Pseudomonas species are gram-negative bacteria that persist in soil, water, animals, and the plant rhizosphere. Pseudomonads produce many antimicrobial...
process using water as solvent proves a success. The optical resonances from TA remarkably alter the excited state of Cu ions by means of a strong or weak coupling regime between them and this was further analysed using optical intrinsic Urbach energy. Such behavior led to the overall changes ...
The available data on heat-flow and seismic wave speeds suggests that the chemical composition of the lower crust in many regions mainly is close to andesitic and dacitic (Gao et al., 1998; Hacker et al., 2011, 2015; Rudnick and Gao, 2003; Wang et al., 2018). The lithology of the...
Preparation of the dye solution The cationic dye MG (Fig.1; chemical formula: C46H50N42C2HO4C2H204, MW: 927.1 g/mol) was purchased from MERCK Pvt. Ltd(England). A 1 g sample of the appropriate MG was dissolved in 1000 mL of distilled water to produce an MG stock solution of 1000 ...
(TG) indicated that the mass loss occurs at temperatures below 100 °C, being attributed to the presence of unbound water. The same was observed for Al2O3AP. The mass losses below 100 °C were ignored in thermodynamic modelling calculations since the raw meals were dried in an oven at ...
