The present invention relates to a transition metal organic framework, comprising: a transition metal oxide having antibacterial or antifungal properties; and an organic compound having at least one hydrophilic functional group, wherein the organic compound is bound to the transition metal oxide to surround the transition metal oxide and the hydrophilic functional group is placed toward the outside of the transition metal organic framework.

Catechol metal complex compounds of formula (I)

##STR00001##

are colored and can be used to give color to surfactant compositions. Detergents containing these catechol metal complex compounds do not stain the textile even after repeated use.

A multi-component detergent, including at least two components, that is contained in a container having at least two chambers, wherein a first component K1 is a first liquid composition, containing at least one catechol metal complex compound of formula (I)

##STR00001##

and at least one free catechol compound of formula (II) or the salt thereof

##STR00002##

with the proviso that the catechol compound of formula (II) and the salt thereof are different from the compounds of formula (I), and a second component K2 is a second liquid composition, containing at least one surfactant. The present invention further relates to the use of the multi-component detergent for removing bleachable stains and a method for washing textiles using the multi-component detergent.

The present disclosure relates to a preparation method of a methionine-metal chelate, and the methionine-metal chelate, which is prepared by first reacting Ca(OH).sub.2 and methionine and adding metal chloride salts, can be used as feeds and feed additives.

Metal coordination complexes comprising at least one diazabutadiene based ligand having a structure represented by: ##STR00001## where A.sub.1, A.sub.2, A.sub.3, and A.sub.4 are atoms in a 6-membered ring and are independently selected from C, N, O, S, and P; and where R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, and R.sub.6 are independently selected from the group consisting of H, amino groups, C1-C6 alkyl groups, or C4-10 cycloalkyl groups; and further provided that alkyl groups may optionally contain silicon; and where the metal coordination complex is capable of participating in a Diels-Alder type reaction with a dienophile. Processing methods using the metal coordination complexes are also described.

The invention discloses use of a uranium-containing compound as a scintillator. The uranium-containing compound is a uranium-containing organic-inorganic hybrid compound or a uranium-containing inorganic compound. The uranium-containing organic-inorganic hybrid compound is a uranium-containing organic carboxylate or a uranium-containing organophosphate. The uranium-containing inorganic compound is a uranium-containing non-metallate, a uranium-containing metal salt, or a uranium-containing halide. The invention discloses the uranium-containing organic-inorganic compound or the uranium-containing inorganic compound having intrinsic scintillating ability, and provides a new concept and method for the development of (organic-inorganic, inorganic) scintillators of various chemical compositions and configurations with the uranium element.

Systems and methods for enhancing the stability and efficiency of perovskite materials, and devices incorporating such perovskite materials. A method of making a perovskite layer includes mixing a perovskite solution with a silica shell precursor solution to produce a perovskite-silica precursor solution, and spin casting or drop casting the perovskite-silica precursor solution on a substrate to form a perovskite material or material layer, wherein the perovskite material or material layer includes a plurality of groups of one or more perovskite grains, each of said plurality of groups wrapped in a silica shell. The silica shell precursor solution may have a chemical structure of R.sub.n—Si—(OR).sub.4-n, where “R” is an alkyl, aryl, or organofunctional group, and “OR” is a methoxy, ethoxy, or acetoxy group.
