Jul 19, 2011 zinc-finger nucleases zfns are powerful tools for producing gene knockouts kos with high efficiency. whereas zfn-mediated gene disruption has been demonstrated in laboratory animals such as mice, rats, and fruit flies, zfns have not been used to disrupt an endogenous gene in any large domestic species. here we used zfns to induce a biallelic knockout of the porcine 1,3 ...
This type is mainly used for surface cleaning and intensification, rust removing of various middle and small-size casting and workpieces. shot-blasting machine has the advantages of advanced design, reasonable structure, little energy consumption and high efficiency.
The zas project is a consortium consisting of nine european partners joining forces to develop a cost efficient zinc-air secondary battery for efficient energy storage. the consortium represents the entire value chain from material developers and producers to battery manufacturer and end user.
Thats why we work hard to perfect a process that maximizes benefits while taking advantage of in-house capabilities for simplicity and efficiency. understanding the benefits depending on the type of metal being cast, a hot-chamber conventional or hot-chamber multi-slide 4 slides machine is used for zinc die-castings, and a cold-chamber ...
