Title: Microbial cleaning of hydrocarbon-contaminated soil - by adding complexing agent, pref. cyclodextrin, to increase bio-availability of hydrocarbon
Inventor: MUELLER-MARKGRAF WOLFGANG DR
IPC: C12S9/00
Filed: 1992-11-13
Abstract: Microbial cleaning of soil contaminated by hydrocarbons (I), esp. aromatic (I), is improved by adding a complexing agent (II) for (I) directly to the soil or to at least part of a sepd. contaminated soil layer. (II) pref. forms an inclusion complex with polycyclic aromatic (I), monocyclic aromatics (BTX) and/or aliphatic (I). (II) is esp. cyclodextrin (IIa). (II) is added to the fines of a sepd. soil layer, after removal of coarse particles by wet classification. (II) is mixed with the soil fines in a bioreactor, and (I) are microbially degraded with controlled nutrient addn., oxygen supply and pH adjustment. Esp. (II) is added to the suspended fines with mixing for 30-60 mins. to form a suspended or colloidally dissolved (I)/(II) complex, followed by microbial degradation for several days and repeating the first stage (i.e. mixing with (II)). ADVANTAGE - By forming a complex with (II), (I) are desorbed from fine soil particles and made available to microorganisms, esp. if (I)/(II) complexes are water-soluble or form a colloidal soln. or stable suspension. The increased bioavailability of (I) accelerates degradation and improves the cleaning efficiency. Unlike surfactants, (II) are non-toxic to microorganisms and do not disrupt biological membranes.

Inventor: HAMAMOTO SATOSHI
IPC: H01L21/02
Filed: 1993-01-28
Abstract: The prodn. involves (a) forming on a heat resistant substrate, a layer having a breaking stress in the thickness direction which is less than that in a direction perpendicular to the thickness direction; (b) forming a thin semiconductor film which is high temp. heated; (c) adhering a support substrate on the surface of the film; and (d) breaking the anisotropic layer by applying mechanical stress to the two substrates so the breaking stress acts in the thickness direction of the layer and the film separates from the heat resistant substrate. The anisotropic layer is pref. a thin layer of flocculant graphite with a crystal or layer structure in the thickness direction which differs from that in the direction perpendicular to the thickness direction, the graphite layer is bonded to the heat resistant substrate by a carbon or ceramic based binder. After breakage of the graphite layer, fragments are removed (by brushing or etching) from the film, a high impurity concn. region is produced in the thin film by inward diffusion from the surface, and a back electrode is produced on the thin film above the high impurity concn. region. ADVANTAGE - The prodn. combines favourable thin film prodn. on the heat resistant substrate with simple transfer of the thin film to a support substrate e.g. of glass, so a high quality solar cell is mfd. with high reliability and low cost.
