Abstract:
Provided is a technique for fabricating a novel thin membrane with a starting material such as a biocompatible compound that is not easily processible into a membrane, particularly a technique for fabricating a novel thin membrane of a composition that is gradually polymerized from a membrane surface into the membrane in the cross sectional direction of the membrane, and having, for example, different structures on the front and back of the membrane. The technique includes the steps of preparing a solution of a starting material compound; forming a thin membrane of the solution on a base material surface; and forming the organic polymer thin membrane through a polymerization reaction caused by irradiating the exposed surface of the thin membrane with a plasma or an electron beam.
Abstract:
An ammonia synthesis catalyst having high activity is obtained by having a two-dimensional electride compound having a lamellar crystal structure such as Ca 2 N support a transition metal. However, since the two-dimensional electride compound is unstable, the stability of the catalyst is low. In addition, in cases where a two-dimensional electride compound is used as a catalyst support, it is difficult to shape the catalyst depending on reactions since the two-dimensional electride compound has poor processability. A composite which includes a transition metal, a support and a metal amide compound, wherein the support is a metal oxide or a carbonaceous support; and the metal amide compound is a metal amide compound represented by general formula (1). M(NH 2 ) x ···(1) (In general formula (1), M represents at least one metal atom selected from the group consisting of Li, Na, K, Be, Mg, Ca, Sr, Ba and Eu; and x represents the valence of M.)
Abstract:
An object is to provide a flow pattern regular expression creating method, a regular expression creating apparatus, and a program enabling provision of a new representation method enabling one-to-one correspondence to a flow pattern. A regular expression creating method of creating a regular expression of a flow pattern in a multiply connected exterior domain with N (N is an integer equal to or larger than 1) holes topologically includes a graph representation creating step of creating a graph representation having one-to-one correspondence to the flow pattern; and a regular expression creating step of creating a regular expression from the graph representation that is created at the graph representation creating step.

Further, a method for producing oils, comprising the steps of culturing the IPM33-18 strain or the like in a medium containing a carbon source to allow oils to accumulate in a culture, and collecting the oils from the culture is provided. According to this production method, the oils can be collected from a liquid fraction of the culture.
Abstract:
It is intended to provide: a compound useful as an amyloid oxidation catalyst which is applicable in vivo and is applicable not only to Aβ peptides but to other amyloids; and a prophylactic or therapeutic drug for an amyloid-related disease, comprising the same. The present invention provides a benzothiazole compound represented by the following formula (1) wherein X represents a halogen atom; R 1 represents an optionally substituted hydrocarbon group; R 2 represents a hydrogen atom or an optionally substituted hydrocarbon group; R 3 and R 4 are the same or different and each represent a hydrogen atom, an optionally substituted hydrocarbon group, an alkoxy group, a halogen atom, an amino group, a nitro group, or a cyano group; R 2 and R 4 optionally together form an alkylene group; and R 5 represents an anion.
Abstract:
A DNA sensor is provided which is capable of identifying unknown DNA with enhanced detection sensitivity of the hybridization. A p-channel field-effect transistor having an electrolyte solution gate 8 and having as a p-channel 5 a diamond surface 2 which contains a mixture of at least a hydrogen-terminated surface and a surface terminated with an amino group or a molecule with an amino group is configured along with a probe DNA 11 constituted of a single-stranded DNA with known nucleotide sequence which is directly immobilized by a linker to the diamond surface 2 and with a target DNA constituted of an unknown single-stranded DNA which is dropped on the diamond surface 2. When the target DNA is in complementary relationship to the probe DNA 11, negative electric charge of the phosphate group of a double-stranded DNA produced by the hybridization of the probe DNA 11 with the target DNA both constituted of a single-stranded DNA is doubled, thereby resulting in increase of the hole density in the p-channel and shift of the threshold voltage of the p-channel field effect transistor toward positive direction. By detecting this shift of the threshold voltage toward positive direction, an identification can be made on whether or not the target DNA is in complementary relationship to the probe DNA 11.
