ANTE: Abstracts
in New Technologies and Engineering
ANTE: Abstracts in New
Technologies and Engineering (formerly Current
Technology Database), is an abstracting and indexing
service monitoring publications from the U.K. and the
U.S. Coverage includes new technologies such as
information technology and computing, electronics,
biotechnology, medical technology, as well as
engineering (including construction, electrical and
chemical engineering) and allied subject areas.
Abstracts are available from January 1993 to the
present.
Sources covered include over 350 periodicals,
conference proceedings, technical reports, trade
journal/newsletter items, patents, books, and press
releases.
Subject Coverage
Dates of Coverage
Approximately
1981-current. The oldest record in the database has

Abstract
A base porphyrin, etioporphyrin (EPI), was
synthesized and a number of metal-etioporphyrin
compounds were derived from EPI by metal
insertion, these being nickel, vanadyl,
palladium and platinum. The metal-etioporphyrins
were supported on silica gel with various
loadings to be employed as catalysts for
hydrocarbon cracking and to a minor extent for
hydrogenation. The porphyrins themselves were
characterized using temperature programmed
decomposition (TPD), temperature programmed
reduction (TPR), mass spectroscopy (MS) and
infra-red (IR) spectroscopy. TPD studies up to
550C indicated complete stability and TPR
studies (20-500C) showed interaction with
hydrogen, nickel-EPI and Pd-EPI especially
showing strong interaction. (Original abstract -
