摘要: In order to appreciate the impact of the properties of liquid sulphur dioxide and liquid sulphur trioxide on future technology, it is important that an in-depth analysis of their properties be understDOI: 10.1007/978-3-319-22641-5_2 被引量: 2 ...
The influence of hydrochloric or sulphuric acid treatment on the electro-physical properties of superthin basalt fiber (STBF) made from Armenian basalt rocks was studied. Specific electric resistance for direct and alternating currents, dielectric parameters of εand εwere measured. It is shown that...
This acid is named disodium salicylate, which upon undergoing further reaction with sulphuric acid leads to the formation of salicylic acid. Physical Properties of Salicylic Acid Salicylic acid is a colourless, odourless and needle-shaped crystals at room temperature. The taste of salicylic acid is ...
The processes of humification occur mainly under aerobic conditions. Animals that live in the soil may initially reduce the size of the fresh organic residues. Further transformations are promoted by the activity of the enzymes of bacteria and fungi living in the soil. Cellulose, proteins and fats...
A filed experiment was conducted at Bahtim agricultural research station, Kalubia Governorate, Egypt, during two successive seasons, summer 2019 and winter 2019/2020 to study the effect of acid and base compost pretreatment on some soil physical properties and sorghum (Sorghum bicolor, cv. Giza 15...

The chemical composition of the different ALE extracts was characterized by several different and complementary analytical methods: biochemical colorimetric assays (polysaccharides, proteins, humic substances), FTIR, Raman spectroscopy and enzymatic tests. The mechanical properties of hydrogels were quantified ...

1.4 friction properties Yak hair is less resistant to wear than cashmere and wool, but better than camel hair and seahorse hair. The friction coefficient of yak hair is higher than that of 70 wool, but it is better than cashmere. It is not easy to tear off with hand, and it is also...
The Eyjafjallajökull aerosol plume was sampled and characterised in terms of physico-chemical properties as it descended into the boundary layer. During the initial intensive explosive phase of the eruption, with low SO2 emissions, the submicron modal diameter was of the order of 185 nm, while...
