The purpose of the study was to determine chemical composition and dry matter yield of cowpea haulms (Sejwaleng, Lebudu and Morathathane) grown in Limpopo Province, South Africa. Randomized complete block design was used as an experimental design and plant material was harvested at 14 weeks ...
Are elastic and flexible materialTensile strength between 1 and 4 MPa, there silane modified based epoxy that can reach 8 Mpa.Maximum elongation of 100% to 300%.Chemical properties:Very good resistance to ultraviolet.They can be painted, even shortly be applied (wet on wet).Adhere to a wide...
If the chemical elements’ composition of the formula is against the formula of the “Unknown ion”, this fragment is considered as an unreasonable fragment and will be removed from the spectrum. Once this cleaning step is completed, the similarity of all spectra to the original chimeric ...
英文摘要: OBJECTIVE:To compare the che mical composition differences of raw and fried processed Glycyrrhiza uralensis , and provide reference for clarifying the regularity of chemical composition change before and after processing and material basis of differential use of raw and fried G. uralensis . ...

In this study, UPLC-QTOF-MS technology combined with UNIFI software was used for the first time to characterize the chemical composition of the WDD material reference. The performed research showed that the established method could quickly identify the chemical composition of WDD and quickly evaluate...
For the HPLC-Q Exactive-Orbitrap-MS analysis, the raw material (brown powder; 0.4 g) of the LHQW capsule was accurately weighed, dissolved in 60% methanol (V/V; 20 mL), and sonicated for 30 min. The solution was centrifuged at 12,000 r/min and the supernatant was filtered through a...
This standard covers the mechanical properties, chemical composition, weldability, cleanability, and surface requirements for low carbon mild steel products. This standard also provides substrate requirements for coated mild steels covered under material standard MS-6000<D>. Continuously cold rolled flat...
