Here we report a new three-dimensional nickel-based hybrid structure [Ni3(BTB)2(BPE)4(H2O)2]·2DMF·2H2O, 1 [where BTB = 1,3,5-tris(4-carboxyphenyl)benzene and BPE = 1,2-bis((4-pyridyl)ethane)], which exhibits long-range ferromagnetism and semiconductor behavior. The dipolar interaction between the magnetic spins is suggested to explain the development of long-range ferromagnetic ordering, where the superexchange interaction can be unwanted due to the large distance between the magnetic spins. Optical band gap and resistance vs. temperature measurements reveal the semiconductor nature of this compound. The density of states calculations shed light towards the origin of the low band gap value.

A series of metal-organic frameworks based on alkaline earth metal ions (Ca, Sr and Ba) and 1,3,5-benzenetribenzoic acid (BTB) have been synthesized and characterized. These are [H2N(CH3)2][Ca7(BTB)5(H2O)8(DMF)4]·4H2O (1), [H2N(CH3)2]2[Sr5(H2O)6(BTB)4] (2) and [H2N(CH3)2][Ba(H2O)(BTB)] (3). All the structures are three-dimensional in nature with different secondary building units. Compound 1 contains one-dimensional Ca-O-Ca zigzag chains while compound 2 contains Sr5O28 pentameric clusters and compound 3 contains one-dimensional Ba-O-Ba chains. Both compounds 1 and 3 form (3,6)-net connectivity while compound 2 forms (3,12)-net connectivity. Optical band gap energy measurements show that compound 1 (2.65 eV) has low band gap energy compared to 2 (3.22 eV) and 3 (3.32 eV). This variation in band gap energy may be due to the difference in structural arrangement. Compound 3 crystallizes in a non-centrosymmetric space group (Pna21), which belongs to the polar point group C2v. This compound displays a strong SHG response and good ferroelectric and piezoelectric properties.

Over the past decade, there is excellent evidence in the scientific literature that contaminated environmental surfaces and noncritical patient care items play an important role in the transmission of several key health care?associated pathogens including methicillin-resistant Staphylococcus aureus, vancomycin-resistant enterococci, Acinetobacter, norovirus, and Clostridium difficile. Thus, surface disinfection of noncritical environmental surfaces and medical devices is one of the infection prevention strategies to prevent pathogen transmission. This article will discuss a bundle approach to facilitate effective surface cleaning and disinfection in health care facilities. A bundle is a set of evidence-based practices, generally 3-5, that when performed collectively and reliably have been proven to improve patient outcomes. This bundle has 5 components and the science associated with each component will be addressed. These components are: creating evidence-based policies and procedures; selection of appropriate cleaning and disinfecting products; educating staff to include environmental services, patient equipment, and nursing; monitoring compliance (eg, thoroughness of cleaning, product use) with feedback (ie, just in time coaching); and implementing a ?no touch? room decontamination technology and to ensure compliance for patients on contact and enteric precautions. This article will also discuss new technologies (eg, continuous room decontamination technology) that may enhance our infection prevention strategies in the future.

VANOL and VAPOL ligands are known to react with three equivalents of B(OPh)3 to form a catalytic species that contains a boroxinate core with three boron atoms, and these have proven to be effective catalysts for a number of reactions. However, it was not known whether the closely related BINOL ligand will likewise form a boroxinate species. It had simply been observed that mixtures of BINOL and B(OPh)3 were very poor catalysts compared to the same mixtures with VANOL or VAPOL. Borate esters of BINOL have been investigated as chiral catalysts, and these include meso-borates, spiro-borates, and diborabicyclo-borate esters. Borate esters are often in equilibrium, and their structures can be determined by stoichiometry and/or thermodynamics, especially in the presence of a base. The present study examines the structures of borate esters of BINOL that are produced with different stoichiometric combinations of BINOL with B(OPh)3 in the presence and absence of a base. Depending on conditions, pyro-borates, spiro-borates, and boroxinate species can be generated and their effectiveness in a catalytic asymmetric aziridination was evaluated. The finding is that BINOL borate species are not necessarily inferior catalysts to those of VANOL and VAPOL but that, under the conditions, BINOL forms two different catalytic species (a boroxinate and a spiro-borate) that give opposite asymmetric inductions. However, many BINOL derivatives with substitutents in the 3- and 3?-positions gave only the boroxinate species and the 3,3?-Ph2BINOL ligand gave a boroxinate catalyst that gives excellent inductions in the aziridination reaction. BINOL derivatives with larger groups in the 3,3?-position will not form either spiro-borates or boroxinate species and thus are not effective catalysts at all.

Searching for new chemically durable and radiation-resistant absorbent materials for actinides and their fission products generated in the nuclear fuel cycle remain highly desirable, for both waste management and contamination remediation. Here we present a rare case of 3D uranyl organic framework material built through polycatenating of three sets of graphene-like layers, which exhibits significant umbellate distortions in the uranyl equatorial planes studied thoroughly by linear transit calculations. This unique structural arrangement leads to high beta and gamma radiation-resistance and chemical stability in aqueous solutions within a wide pH range from 3 to 12. Being equipped with the highest surface area among all actinide compounds known to date and completely exchangeable [(CH3)2NH2]+ cations in the structure, this material is able to selectively remove cesium from aqueous solutions while retaining the polycatenated framework structure.

Metal-organic frameworks (MOFs) represent a class of crystalline coordination compounds with periodic structures composed of metal cations or clusters connected by organic linkers. In recent years, increasing interest has been attracted to the synthesis and study of MOFs based on oxophilic cations of early transition metals, first of all, ZrIV, HfIV, TiIV and ScIII, and also main group AlIII cations. The carboxylate complexes of these metals possess high stability, which ensures the chemical robustness of the corresponding coordination polymers. The MOFs based on scandium(III) and oxygen-containing ligands are promising for the design of porous materials possessing high specific surface areas, high hydrolytic and thermal stabilities of the coordination framework and diverse functional properties. This review addresses the chemistry of metal-organic frameworks based on scandium(III). Published data on the synthesis and crystal structure characterization of scandium-containing coordination polymers available before 2018 are discussed. The properties of these compounds are considered.
