Abstract:
... Diamond thin films are known to have properties similar to bulk diamond and have applications in both industry and fundamental studies in academia. The high surface energy of diamond makes it extremely difficult to grow diamond films on foreign substrates. Hence, to grow diamond films on non-diamond substrates, a nucleation step is needed. In this review various techniques used for diamond nucleat ...

Abstract:
... The nursery stages of mussel aquaculture are highly inefficient with most juvenile mussels being lost within the first few months after seeding, although the precise timing of losses is largely unknown. One possibility is that many juveniles are lost at seeding because they are either impaired or killed by the process of transporting juveniles from collection sites to coastal nursery farms, or bec ...

Understanding connectivity between abalone populations and residence times for pelagic larvae within suitable settlement habitats is critical for sustainable management of wild abalone stocks and ranching schemes. In the Eastern Cape region of South Africa, poaching has severely depleted wild abalone Haliotis midae populations. Rebuilding stock through larval seeding is being considered as a poten ...

However, despite this ample literature, clear guidelines about the effectiveness and feasibility of the different restoration techniques in environmental contexts showing variable responses still lack. Furthermore, postfire hydrolog ...
