Extracting Picosecond Time Constants from Steady-State Spectroscopy: A Physical Chemistry Experiment

Journal of Chemical Education, 2013
Femtosecond spectroscopy is a key technique in modern physical chemistry research. Thus, femtosecond techniques, as well as molecular processes occurring on femto- to picosecond time scales, should be included in a physical chemistry curriculum. Usually, experiments covering the topic are challenging due to costly equipment and laser safety issues.

Steady-State Land Cover but Non-Steady-State Major Ion Chemistry in Urban Streams

Environmental Science & Technology, 2018
Sources of many major ions in urban streams remain ambiguous, particularly for ions unrelated to deicing salt use, and temporal patterns in concentrations are unstudied. We used 16 years of water chemistry data based on weekly samples from the Baltimore, MD, USA, metropolitan area and the Weighted Regressions on Time, Discharge, and Season approach to ...

Testing the steady-state water chemistry model predictions of pre-industrial lake pH with paleolimnological data from northern Sweden☆

Science of The Total Environment, 2008
Criteria are needed for distinguishing naturally acid water from that acidified by air pollution, especially in the organic-rich waters of northern Sweden. The Steady-State Water Chemistry Model (SSWC) was augmented to include organic acidity so that it could predict pre-industrial pH in organic-rich waters.

An Efficient Wavelet Based Approximation Method to Steady State Reaction–Diffusion Model Arising in Mathematical Chemistry

The Journal of Membrane Biology, 2014
The mathematical model of Rahamathunissa and Rajendran (J Math Chem 44:849-861, 2008) in an amperometric biosensor response is discussed. In this paper, we have applied the shifted second kind Chebyshev wavelets (CW) to obtain the numerical solutions of reaction-diffusion equations containing a nonlinear term related to Michaelis-Menton kinetics of the

Critical loads and steady-state chemistry for streams in the state of Maryland

Environmental Pollution, 1992
The critical loads to streams, steady-state stream chemistry and catchment chemical weathering rate in 73 catchments has been determined in the state of Maryland, USA. It was calculated with the PROFILE model from chemical limits for biological indicators, soil mineralogy, soil texture, annual average temperature, average soil moisture, net long-term ...
