Effects of salinity changes on the photodegradation and ultraviolet–visible absorbance of terrestrial dissolved organic matter
We performed laboratory studies to determine the effects of salinity on the photodegradation of dissolved organic matter (DOM) from the Great Dismal Swamp, Virginia, an important source of terrestrial DOM to the lower Chesapeake Bay. Samples were created by mixing Great Dismal Swamp water (ionic strength < 0 mol L21) with modified artificial seawater solutions of differing salinities while keep...
متن کاملHigh-throughput on-the-fly scanning ultraviolet-visible dual-sphere spectrometer.
We have developed an on-the-fly scanning spectrometer operating in the UV-visible and near-infrared that can simultaneously perform transmission and total reflectance measurements at the rate better than 1 sample per second. High throughput optical characterization is important for screening functional materials for a variety of new applications. We demonstrate the utility of the instrument for...
متن کاملVisible and near-ultraviolet absorption spectrum of liquid water.
The optical absorption of pure liquid water in the 300-700-nm region has been measured by use of a long (1.5-m) path-length cell. The absorption spectrum coincides well with the edge of previous data in the 200-320-nm region and provides reliable data in the 320-420-nm region that has until now been a region of considerable unreliability. The data obtained for the 420-700-nm region agree quite ...
متن کاملInvestigations on Optoelectronic Properties of New low Gap Compounds Based on Pyrrole as Solar Cells Materials
In this paper theoretical study by using DFT method on three conjugated compound based on 2-styryl-5-phenylazo-pyrrole is reported. These dyes contain one carboxy, two carboxy and one sulfonic acid anchoring groups, the aim is to investigate their effects on the electronic structure. The theoretical knowledge of the HOMO and LUMO energy levels of the components is cannot be ignored in investiga...
متن کاملInvestigations of New Low Gap Conjugated Compounds Based on Thiophene-Phenylene as Solar Cells Materials
The research in new organic π-conjugated molecules with specific properties has become one of the most interesting topics in fields of materials chemistry. These materials are promising for optoelectronic device technology such as solar cells. On the other hand, the use of low band gap materials is a viable method for better harvesting of the solar spectrum and increasing its efficiency. The co...
