We have designed a novel semiconductor core/layer nanostructure of a uniform ZnO@TiO2 nanorod array modified with a ZnIn0.25Cu0.02S1.395 solid-solution on the surface via a facile hydrothermal synthesis. This novel nanostructure combines the merits of all components and meets the requirements of photovoltaic system application. An intimate PN heterojunction is formed from the ZnO@TiO2 nanorod a...

p-tert-Butylcalix[4]arene is a bowl-shaped molecule capable of forming a range of polynuclear metal clusters under different experimental conditions. p-tert-Butylcalix[8]arene (TBC[8]) is a significantly more flexible analogue that has previously been shown to form mono- and binuclear lanthanide (Ln) metal complexes. The latter (cluster) motif is commonly observed and involves the calixarene ad...

The Fule deposit is a typical Cd-, Ge- and Ga-enriched Pb-Zn located in the southeast of Sichuan–Yunnan–Guizhou polymetallic ore province China. Zoned, euhedral cubic pentagonal dodecahedral anhedral pyrites were observed, they are thought to comprise two generations. First generation pyrite (Py1) homogeneous entirely confined crystal core, whereas second (Py2) forms bright irregular rims aroun...

Exploration of copper ore in the Nepal Himalayas has been carried out by different researchers at times. The author conducted detailed geological studies and mineral exploration some polymetallic prospects also reviewed literature related to Nepal. present research is able delineate two distinct mineralization belts extending from west east identify promising sites for that could be feasible mi...

Mineralization is an essential requirement for normal skeletal development, but under certain pathological conditions organs like articular cartilage and cardiovascular tissue are prone to unwanted mineralization. Recent findings suggest that the mechanisms regulating skeletal mineralization may be similar to those regulating pathological mineralization. In general, three forms of cell-mediated...

Extracellular matrix (ECM) mineralization is a physiological process in bone and a pathological one in soft tissues. The mechanisms determining the spatial restriction of ECM mineralization to bone physiologically are poorly understood. Here we show that a normal extracellular phosphate concentration is required for bone mineralization, while lowering this concentration prevents mineralization ...

In this Perspective, we highlight the non-innocent behaviour of the bridging ligand in organometallic polynuclear metallic complexes displaying metal-carbon σ bonds between the metallic units and a strongly coupled conjugated carbon-rich bridging ligand. With the help of representative experimental and theoretical studies on polymetallic systems, but also on monometallic complexes, we point out...
