Sulfate reducing bacteria (SRB) wreaks havoc in the oil industry by being an agent for oil souring and building corrosion in pipelines and thereby degrade the quality of crude oil. Palladium nanoparticles decorated silicon carbide nanomaterial (Pd-SiC) was synthesized by a facile single step syn...

Platinum group metals (PGMs) are highly demanding metals in current high-techs. However, their supply is limited due to their scarcity in natural resources and expensive mining. Solvent extraction in combination with microbial communities were employed for the recovery of palladium from aqueous ...

Palladium (Pd) has drawn worldwide attentions because its connections to industry, chemistry, biological material and public health. Quantitative and selective detection tools for Pd and its ion forms are in urgent necessity. Here an umbelliferone derivative Umb-Pd2 was provided as a small, stea...

An enantioselective palladium-catalyzed C(sp2)-H carbamoylation for the preparation of chiral isoindolines was described for the first time. With chiral monophosphorus ligand (R)-AntPhos as the ligand, a series of chiral isoindolines were prepared from diarylmethyl carbamoyl chlorides in excelle...

This paper aims at giving a historical perspective on the work made at Perugia University in the field of proton conducting materials based on layered phosphates, phosphonates and organophosphates, and at commemorating Professor Giulio Alberti, one of the most authoritative scientists who pionee...

The conductivity of a mesoporous zirconium phosphate pyrophosphate of composition Zr(P2O7)0.81(O3POH)0.38 and surface area of 215 m2/g has been determined as a function of temperature at controlled relative humidity. Ac and dc conductivity measurements carried out on pellets with platinum electr...

Heterovalent substitution in zirconium pyrophosphate (ZrP2O7) represents a particular interest due to limited theoretical knowledge in this area and technological importance of the related compounds. Our investigation is focused on Zr4+-Cu2+ substitution in the ZrP2O7 structure. The formulas Zr1...

Designing and fabricating catalysts with highly dispersed metal nanoclusters (NCs) is very crucial for achieving high activity and selectivity. In this work, all-alkynyl-protected [Ag74(C≡CPh)44](NO3)2 cluster (Ag cluster) with a well-defined structure was firstly intercalated in α-zirconium p...

The improvement of catalytic technology in oxidation of organic compounds especially renewable resources to value-added compounds is currently extended. In this work, the well-ordered mesoporous structure of KIT-6 was synthesized. Then, a mixture of vanadyl pyrophosphate and zirconium pyrophosph...

Retrieving silver from available resources, especially the electronic scraps (E-scraps), is becoming more important due to increasing demand for electronic industry and rapid growth in disposal problems of the E-scraps. Although chemical leaching has been extensively employed to retrieve the sil...

In this work, the mechanisms of chloride binding in alkali-activated slag (AAS) pastes are studied, towards a better understanding of the role of activator composition (i.e., NaOH, Na2CO3, Na2SO4, KOH, and K2CO3 solutions) on its chloride binding capacity. The impact of chloride on the mineralog...

The history of zinc chloride therapy before and including Frederic E. Mohs’ (1910-2002) early contributions to dermatologic oncology is presented. In 1932, Mohs devised a method of cutaneous surgery that employed zinc-chloride paste to devitalize basal or squamous cell carcinoma. Because zinc c...

The predominant forms of the dimeric enzyme glutathione S-transferase were purified from rat liver. Forms YbY′b and YbYb (also known as forms C and A, respectively) could be almost completely inhibited by 2,4-dichlorophenoxyacetate (2,4-D). Half-maximal inhibition was obtained at 0.5 mm 2,4-D. ...

The amino acid conjugation of the phenoxyherbicides 2,4-dichlorophenoxyacetate (2,4-D) and 2,4,5-trichlorophenoxyacetate (2,4,5-T) by animals was examined at the level of the enzymes catalyzing the reactions. The phenoxyherbicides were not substrates for the bile acid conjugating system but were...

The phenoxyacid herbicides, 2,4-dichlorophenoxyacetate (2,4-D) and 2,4,5-trichlorophenoxyacetate (2,4,5-T), inhibit all known isoenzymes of human liver and erythrocyte glutathione (GSH) S-transferase. However, the maximal inhibition and the I50 values vary significantly for different isoenzymes....

2,4,5-Trichlorophenoxyacetate (2,4,5-T) has been shown to undergo renal tubular secretion in the isolated perfused rat kidney, especially when a dextran perfusate was used to limit 2,4,5-T-colloid binding. This renal transport of 2,4,5-T led to a high concentration of 2,4,5-T in the kidney and a...

Three novel coordination complexes of copper(II) with 2,4,5-trichlorophenoxyacetate [Cu(γ-pic)3(L)2]·H2O 1, [trans-Cu(en)2(L)2]·2H2O 2 and [Cu2(H2tea)2(L)2]·2H2O 3, where L = 2,4,5-trichlorophenoxyacetate, γ-pic = γ-picoline, en = ethylenediamine, H2tea = monodeprotonated triethanolamine, ...

The levels of PBDEs, alternate BFRs and dechloranes in European Eel (Anguilla anguilla) samples (elvers, yellow and silver eels) were investigated to compare the contamination of eels from the rivers Elbe and Rhine and to estimate the BFR contamination throughout the eel’s life cycle.PBDEs were...

Dechloranes (Decs) have been recently found to occur widely in the environment even in the remote polar regions. However, the understanding of their environmental fate is rather limited. The Tibetan Plateau (TP) may be an important indicator region to study the long-range atmospheric transport a...

Dechlorane related compounds (DRCs), including Dechlorane Plus (syn-DP and anti-DP), Dechlorane-601, -602, -603 and Chlordene Plus (CP), constitute a group of polychlorinated flame retardants (FRs) that are still of industrial use. In particular, DRCs have been detected in various environmental ...
