The Dynamics of Buprestidae (Coleoptera) in Rocky Highveld Grasslands of Ezemvelo Nature Reserve, Gauteng, South Africa

Publikováno v: The Coleopterists Bulletin. 67:7-15

Buprestidae is a large family of woodboring beetles with nearly 15,000 valid species. The family is well represented in South Africa; however, the distribution and hosts of most species are unknown. The abundance of many species is generally correlat

On the Preferential Etching of GaAs by H 2 SO 4 ‐ H 2 O 2 ‐ H 2 O

Autor: D. N. MacFadyen

Publikováno v: Journal of The Electrochemical Society. 130:1934-1941

The preferential etching of gallium arsenide in has been studied. A mechanism for the etching process is discussed drawing on observation by optical and scanning electron microscopy, published results on U H V surface analysis, and surface state mode
