ACS Announces Agreement with Portico ACS announces major agreement with Portico for permanent electronic archiving of journal content. View press release. ACS AuthorChoice Option ACS AuthorChoice allows authors to sponsor the open availability of their articles on the web at the time of online publication. ● Listen to Associate Editor Rajendrani Mukhopadhyay discuss the research featured on the...
INTRODUCTION To describe the relationship between analytical chemistry and automation is at the same time to describe the present position of both these fields, each of which strongly influences the other. We must give each its proper terms, and define the limits of their application. In so doing, we are considering not only the present position of analytical chemistry in its relationship to ot...
The International Congress on Analytical Chemistry was held in Japan, under the sponsorship of IUPAC and the Science Council of Japan in April 1972. This is a report on the progress of analytical chemistry in Japan which I gave as the opening lecture of the Congress, in commemoration of the 20th anniversary of the Japan Society for Analytical Chemistry. Analytical chemistry courses were first e...
During an exposure, humans and animals are most often exposed to a mixture rather than individual mycotoxins. In this study, a Human Embryonic Kidney 293 cell (HEK-293) fluorescence sensor was developed to detect and evaluate mycotoxins, deoxynivalenol (DON) and zearalenone (ZEN) compounds, produced by Fusarium culmorum that are common food contaminants. TRE-copGFP (green fluorescent protein) a...
where Ca and Cb are the analytical (starting) concentration of the acid and base, respectively. Over the past 50 years, chemists have elaborated upon Charlot’s method so that variations upon the “proton accounting” theme are plentiful. The investigators are correct to note that a properly written proton balance equation will not violate the conservation of charge and makes explicit use of charg...
A large fraction of the field of supramolecular chemistry has focused in previous decades upon the study and use of synthetic receptors as a means of mimicking natural receptors. Recently, the demand for synthetic receptors is rapidly increasing within the analytical sciences. These classes of receptors are finding uses in simple indicator chemistry, cellular imaging, and enantiomeric excess an...
nano sio2/hyperbranched polyglycerol (hpg)/so3h catalyst was readily prepared for first time from inexpensive starting materials in aqueous media which catalyzed the synthesis of benzoic acid. ftir spectra, x-ray diffraction (xrd) and transmission electron micrographs (tem) was employed to characterize the properties of the synthesized nano sio2/hpg/so3h. high catalytic activity and ease of rec...
amidoalkyl-2-naphthols as synthetic intermediates play an important role in medicinal chemistry due to their remarkable biological and many pharmacological properties. owing to the versatile biological activities, industrial and synthetic applications of these compounds, introduction of an alternative methodology is urgent in synthetic organic chemistry. low yield and harsh reaction conditions ...
