Spectroscopy in Sustainable Soil Management

Posted on: November 21st, 2019

Agricultural research of today goes into feeding the world’s population tomorrow. Year after year, farmers try to produce more food out of the same resources, and rapidly changing climate conditions only heighten the pressure on the world’s food supply. Changing weather patterns means droughts deepen, floods are more frequent, extremes of heat and cold swing…

Spectra Feature: Electrochemical Response

Posted on: September 26th, 2019

Background This spectra feature was provided by Pine Instruments as an example of a spectroelectrochemistry application that measures electrochemical response over a range of applied electrical potential and correlated against energy absorption by wavelength. Researchers Greenlee, et al. were measuring the electrochemical response of PMDI’s that were functionalized with 4-(dimethylamino) pyridinium (DMAP+) groups.  The functionalization…

Spectroelectrochemistry Applications and Instrumentation

Posted on: September 26th, 2019

Electrochemistry is an extremely valuable tool for examining the kinetics of a wide range of oxidation-reduction reactions.  In these types of reactions, electrons are exchanged between atoms spontaneously,  which forms the basic physical principle behind chemical batteries.  Just as specific oxidation-reduction reactions can cause electron flow, i.e. current, the same process can also work in…
