In recent years acenaphthene has been found to cause polyploidy in plants. Shmuck (1938), Kostoff (1938a, 1938b), Navaskin (1938), and Shmuck and Gusseva (1939) have indicated that acenaphthene may be superior to colchicine for inducing mutations in higher plants. Ark (1946) reported that induced, permanent mutations were formed in broth saturated with acenaphthene in Phytomonas michigatiensis ...

Poly (urea-formaldehyde) (PUF) shelled dicyclopentadiene (DCPD) microcapsules were prepared by in-situ polymerization technology for self-healing concrete applications. It’s found, during the process, sodium dodecyl benzene sulfonate (SDBS) behaves better in emulsification of DCPD than other surfactant of sodium lauryl sulfate (SLS) and styrene maleic anhydride copolymer (SMA), and the addition...

A binary copolymer water treatment agent was synthesized by using maleic anhydride and sodium allyl sulfonate as raw materials ammonium persulfate initiator. The scale inhibition dispersion properties of the were studied through static experiments. results show that has excellent performance. Moreover, polymer is an environment-friendly with good application prospects.

The hyper-eutrophic conditions in impoundments used for irrigation around South Africa’s major cities promote the co-existence of linear alkylbenzene sulfonate (LAS) and other pollutants such as metals. combined effects LAS metals, when water is to irrigate crops, has not been properly investigated light human health risks prevailing local conditions. To understand potential risks, pot-culture ...

Tuning the physical-chemical properties of Polypyrrole (PPy) opens up potentially exciting new applications, especially in the area of bacterial adhesion. Polypyrrole is electrochemically synthesised under various conditions and the physical properties of the films and their effects on bacterial adhesion characterised. Five types of dopants, chloride (Cl), Perchlorate (ClO4), pToluene-sulfonate...
