摘要:The present invention is directed to a method for the synthesis of a bi-functional complex comprising a molecule part and an identifier oligonucleotide part identifying the molecule part. A part of the synthesis method according to the present invention is preferably conducted in one or more organic solvents when a nascent bi-functional complex comprising an optionally protected tag or oligonucleotide identifier is linked to a solid support, and another part of the synthesis method is preferably conducted under conditions suitable for enzymatic addition of an oligonucleotide tag to a nascent bi-functional complex in solution.

摘要:The invention relates to an ultrahigh contrast photographic material comprising a support bearing a silver halide emulsion layer, containing a hydrazide nucleating agent in the emulsion layer or a hydrophilic colloid layer, characterised in that the nucleating agent of formula (I) comprises (a) two nicotinamide moieties, which may be the same or different, which are linked by a linking group, and (b) a hydrazide moiety linked to only one of the nicotinamide moieties. The nucleator of formula (I) may be in combination with a nucleator of formula (II) which comprises a dimeric molecule comprising two monomers linked by a linking group, each monomer of which (a) may be the same or different and (b) comprises a hydrazide moiety and a nicotinamide moiety.The photographic material provides unexpectedly good nucleation in the absence of, or with reduced amounts of, booster and in a developer whose pH is variable, and further with lower chemical spread and pepper fog. When the synthesis provides both a compound of formula (I) and (II), the products can be used directly without a separation step, providing a cost advantage.

摘要:A herbicidal composition comprising a pyrimidine formyl oxime derivative and a use thereof. The composition comprises an herbicidal effective amount of an active ingredient A and an active ingredient B, wherein the active ingredient A is (aa) or a salt thereof; and the active component B is selected from one or more of the following compounds and acids/salts/esters thereof: an HPPD inhibitor, a PDS inhibitor, a DOXP inhibitor, an ALS inhibitor, an ACCase inhibitor, a PPO inhibitor, a PSII inhibitor, a microcosmic assembly inhibitor, a synthetic hormone inhibitor, a VLCFA inhibitor, a lipid synthesis (non-acetyl coenzyme A carboxylase) inhibitor, an EPSPS inhibitor, a GS inhibitor, and the like. The composition can effectively control/prevent various weeds and the like, and has the characteristics of expanding an herbicidal spectrum, reducing an application rate, producing a synergistic effect, getting rid of herbicide resistance weeds, and so on.
