“…Thermal decomposition of the dihydrate to the anhydrous MoO 3 under N 2 /H 2 gas leads to a delamination into platelet-like particle shapes by two processes. Firstly, crack initiation by loss of crystallization water with increasing temperature and subsequent crack propagation by the stress from a nonuniform thermal lattice expansion (Sotani 1986;Boudjada et al 1993;Shafaei et al 2016c). As a consequence, the surface area of MoO 3 particles was substantially increased due to the observed delamination.…”

“…aeruginosa. Furthermore, we found that the potentials of the molybdenum oxides to reduce the number of live bacteria are directly affected by the annealing temperature and time in different crystalline structures (Lorenz et al 2011;Zollfrank et al 2012;Gutbrod and Zollfrank 2013;Shafaei et al 2013bShafaei et al , 2016c.

In this study, development of a novel thermoplastic bio-based composite with excellent antimicrobial surface properties is investigated. To the best of our knowledge, this is the first report to evaluate the antimicrobial properties of molybdenum trioxide embedded into a cellulose acetate as biopolymer matrix. The developed composites might step up to innovative applications used in modern medical and public environments.

Molybdenum Oxides – From Fundamentals to Functionality

et al. 2017

View full text Add to dashboard Cite

The properties and applications of molybdenum oxides are reviewed in depth. Molybdenum is found in various oxide stoichiometries, which have been employed for different high-value research and commercial applications. The great chemical and physical characteristics of molybdenum oxides make them versatile and highly tunable for incorporation in optical, electronic, catalytic, bio, and energy systems. Variations in the oxidation states allow manipulation of the crystal structure, morphology, oxygen vacancies, and dopants, to control and engineer electronic states. Despite this overwhelming functionality and potential, a definitive resource on molybdenum oxide is still unavailable. The aim here is to provide such a resource, while presenting an insightful outlook into future prospective applications for molybdenum oxides.

Functional Enzyme Mimics for Oxidative Halogenation Reactions that Combat Biofilm Formation

et al. 2018

View full text Add to dashboard Cite

Transition-metal oxide nanoparticles and molecular coordination compounds are highlighted as functional mimics of halogenating enzymes. These enzymes are involved in halometabolite biosynthesis. Their activity is based upon the formation of hypohalous acids from halides and hydrogen peroxide or oxygen, which form bioactive secondary metabolites of microbial origin with strong antibacterial and antifungal activities in follow-up reactions. Therefore, enzyme mimics and halogenating enzymes may be valuable tools to combat biofilm formation. Here, halogenating enzyme models are briefly described, enzyme mimics are classified according to their catalytic functions, and current knowledge about the settlement chemistry and adhesion of fouling organisms is summarized. Enzyme mimics with the highest potential are showcased. They may find application in antifouling coatings, indoor and outdoor paints, polymer membranes for water desalination, or in aquacultures, but also on surfaces for food packaging, door handles, hand rails, push buttons, keyboards, and other elements made of plastic where biofilms are present. The use of natural compounds, formed in situ with nontoxic and abundant metal oxide enzyme mimics, represents a novel and efficient "green" strategy to emulate and utilize a natural defense system for preventing bacterial colonization and biofilm growth.
