In the present work, we report the synthesis of binary nano metal oxides such as Zinc /Copper Oxide via novel dry synthetic methods such as thermal decomposition of oxalate precursor. The synthesis route involves facile solid-phase mechanochemical activation of a physical mixture of simple copper/zinc salts and oxalic acid, followed by calcination of the as-ground oxalate precursors at 450◦C. X...

Leafy spurge, Euphorbia esula L. is an adventive, perennial weed that infests approximately 1.2 million ha of land in North America. It often forms dense stands that displace native vegetation and useful forage plants on rangelands and in riparian habitats. Leafy spurge is a good candidate for detection via remote sensing because the distinctive yellow-green color of its bracts is spectrally un...

We report vibrationally resolved photoelectron spectroscopy (PES) of Au(2)(CO)(n)(-) (n = 1-3), in combination with relativistic density functional theory (DFT) and ab initio calculations. The ground-state transition in the spectrum of Au(2)CO(-) is broad, containing vibrational structures both in the bending and in the CO stretching modes and suggesting a large structural change from Au(2)CO(-...

This thesis describes the construction of a versatile apparatus to study ultracold quantum mixtures capable of simultaneously cooling fermionic Li and K, as well as the bosonic K. The main features of the experimental setup are presented, in particular the addition of a new species Na, which has enabled the study of the Bose-Fermi mixture Na-K. Three main experimental benchmarks are outlined: f...

The process of vermicomposting with Eisenia fetida has been regarded as a viable solution to the frequent disposal and waste of used coffee grounds. The effects of coffee grounds on earthworms have yet to be fully understood. In a manipulative experiment with varying ratios of coffee grounds and earthworms, we investigate how the amount of coffee grounds affect total earthworm biomass and also ...

We investigate fermion pairing in the unitary regime for a mass ratio corresponding to a ;{6}Li-;{40}K mixture using quantum Monte Carlo methods. The ground-state energy and the average light- and heavy-particle excitation spectrum for the unpolarized superfluid state are nearly independent of the mass ratio. In the majority light system, the polarized superfluid is close to the energy of a pha...

Disinfection by-products were determined in 15 water treatment plants in Beijing City. The effects of different water sources (surface water source, mixture water source and ground water source), seasonal variation and spatial variation were examined. Trihalomethanes and haloacetic acids were the major disinfection by-products found in all treated water samples, which accounted for 42.6% and 38...
