A corrosion inhibiting coating includes a primer layer having incorporated therein corrosion inhibitor-loaded containers which release a corrosion inhibitor in response to electromagnetic irradiation; and a container-free protective top layer which, when intact, prevents spontaneous opening of the containers in the primer layer induced by electromagnetic irradiation, wherein the coating-releases an inhibitor in response to electromagnetic irradiation if the protective top layer contains defective areas which enable direct exposure of the containers to the electromagnetic irradiation.

The invention relates to a radiation detector (1) for detecting low-intensity radiation, especially for detecting individual photons. The radiation detector includes a plurality of rows of image cells (5) with respective pluralities of image cells (5) disposed one after the other and respective signal outputs (6). The radiation to be detected generates signal charge carriers in the individual image cells (5), the charge carriers being transported along the rows of image cells to the respective signal output (6). A plurality of output amplifiers (7) are connected in parallel to one of the signal outputs each of the individual image cell columns and amplify the signal charge carriers. The invention is characterized in that the output amplifiers (7) include respective avalanche amplifiers (8).

The invention relates to a semiconductor detector, in particular a pnCCD detector, for radiation detection, including a guard ring (12, 14) and a readout anode (3, 4) arranged inside the guard ring (12, 14) for reading out radiation-generated signal charge carriers (e−), and also including a clearing contact (9) arranged outside the guard ring (12, 14) for removing the collected signal charge carriers (e−) from the readout anode (3, 4). According to the invention, the semiconductor detector furthermore includes a gap (15, 16) in the guard ring (12, 14) and also a controllable gate (17, 18) which is arranged over the gap (15, 16) in the guard ring (12, 14) and makes the gap (15, 16) in the guard ring (12, 14) permeable or impermeable to the signal charge carriers (e−) to be removed, depending on an electrical actuation of the gate (17, 18).

The present invention relates to a method of preparing porous solids, which method comprises polymerizing, in a salt melt or a eutectic mixture of salt melt containing at least one Lewis acidic salt, cyano monomers having at least one or at least two cyano groups in their molecule, wherein the at least one or at least two cyano groups are bonded to a rigid linking group in the cyano monomer, as well as to the porous solids obtainable by that method. Owing to their porosity and the associated extremely high specific surface area, the porous solids are useful as sorbents, filtering and insulating materials, as well as catalyst carriers.

摘要:
In Caenorhabditis elegans, lin-4 and let-7 enclode 22- and 21-nucleotide RNAs, respectively, that function as key regulators of developmental timing. Because the appearance of these short RNAs is regulated during development, they are also referred to as “small temporal RNAs” (stRNAs). We show that many more 21- and 22-nt expressed RNAs, termed microRNAs, (miRNAs), exist in invertebrates and vertebrates, and that some of these novel RNAs, similar to let-7 stRAN, are also highly conserved. This suggests that sequence-specific post-transcriptional regulatory mechanisms mediated by small RNAs are more general than previously appreciated.
