Enrichment of zeolite and sponge as ethylene absorbent with potassium permanganate was theidea of this study to provide an efficient way to scavenge ethylene during storage period ofthree Rosa hybrida cv. ‘Shiraz’, ‘Avalanche’, and ‘After-party’ cut flowers. A preliminaryexperiment revealed that two mL of potassium permanganate solution (1 mM) was enough toenrich two gra...
Phosphorus in water not only degrades quality but also leads to a waste of resources. In this study, adsorption thermodynamics and kinetics were used study the effect sponge iron on phosphorus removal, filtration bed was simulate removal polluted water. The results showed that maximum theoretical capacity modified increased from 4.17 mg/g 18.18 mg/g. After desorption with mol/L sodium hydroxide...
Sponge structure is a structure widely used in the design of cryptographic algorithms that reduces the design of the algorithms to the design of a permutation or pseudo-random function. The development of sponge-based algorithms and the selection of designs based on this structure in SHA3 and CAESAR competitions increase the need to examine its security against various types of attacks. In the ...
background marine sponge/nano-cuo as a natural catalyst efficiently catalyzed the sulfonylation reaction of p-chlorobenzene sulfonyl chlorides with amines in order to prepare sulfonamides. the advantages included use of a natural catalyst, ease of handling, requirement of a very small amount of catalyst, mild reaction condition and appropriateness to high yield. objectives the current study aim...
