Silicon isotopes indicate enhanced carbon export efficiency in the North Atlantic during deglaciation.
Today's Sargasso Sea is nutrient starved, except for episodic upwelling events caused by wind-driven winter mixing and eddies. Enhanced diatom opal burial in Sargasso Sea sediments indicates that silicic acid, a limiting nutrient today, may have been more available in subsurface waters during Heinrich Stadials, millennial-scale climate perturbations of the last glacial and deglaciation. Here we...
متن کاملEffect of Silicon Nanowire on Crystalline Silicon Solar Cell Characteristics
Nanowires (NWs) are recently used in several sensor or actuator devices to improve their ordered characteristics. Silicon nanowire (Si NW) is one of the most attractive one-dimensional nanostructures semiconductors because of its unique electrical and optical properties. In this paper, silicon nanowire (Si NW), is synthesized and characterized for application in photovoltaic device. Si NWs are ...
متن کاملEvidence for a major change in silicon cycling in the subarctic North Pacific at 2.73 Ma
[1] The initiation of Northern Hemisphere glaciation in the subarctic North Pacific at 2.73 Ma was marked by an abrupt cessation of high opaline accumulation, considered to result from an increased stratification of the water column that should have led to higher utilization of nutrients in the surface ocean. We present a new stable Si isotope-based record of Si utilization that is hard to reco...
متن کاملEffects of Aluminum, Silicon And Ferro Silicon Anti Oxidants in MgO C Refractories
Three different materials (aluminum, ferro -silicon and silicon) were used as antioxidants in order to prevent the decarburization process and to keep and/or increase the final properties in MgO-C refractories. Their effects were compared by measuring the physical and mechanical properties as well as oxidation and the resultant phases and microstructures, in the temperature range of 200-1600 ...
