Biological Synthesis of Copper/copper Oxide Nanoparticles
Metal nanoparticles have gained significant interest in the past decade because of their unique physio-chemical properties which has a potential to be used in a wide range of applications. Recent efforts have gained success in synthesising nanoparticles with excellent shape and size control; however they are largely restricted to chemical methods. There is an increasing focus on eco-friendly ‘g...
متن کاملRack-induced bonding in blue-copper proteins.
The unique spectroscopic properties of blue-copper centers, i.e. the strong charge-transfer band at approximately 600 nm and the narrow hyperfine coupling in the EPR spectrum, are reviewed. The concept of rack-induced bonding is summarized. The tertiary structure of the protein creates a performed chelating site with very little flexibility, the geometry of which is in conflict with that prefer...
متن کاملRecent advances in understanding blue copper proteins
The type 1 (T1) or blue Cu (BC) proteins are a highly studied group of electron transfer (ET) active sites in bioinorganic chemistry. In this review, we cover several more recent results which extend the understanding of the geometric and electronic structure of these interesting Cu ET sites. Spectroscopicmethods in tandemwithdensity functional theory (DFT) and timedependent-DFT (TD-DFT) calcul...
متن کاملNMR in Copper-Oxide Metals.
The anomalous part of the NMR relaxation rate of copper nuclei in the normal state of copperoxide metals is calculated using the orbital magnetic parts of the fluctuations derived in a recent theory to explain the long wavelength transport anomalies. Oxygen and Yttrium reside on lattice sites at which the anomalous contribution is absent at all hole densities. The frequency, momentum dependence...
متن کاملUltrasonic Fabrication of Monodispersed Nano-Copper Oxide
A green environmental friendly process for preparing monodispersed cuprous oxide nanoparticles is reported. In this process, cuprous oxide is prepared using Cu(OH)42- as precursor and glucose as reducing agency in the presence of dispersant under ultrasonic radiation. Spherical, welldispersed Cu2O nanoparticles were obtained with the average size of 200 nm or 1.5 μm, respectively, with or witho...
