A NEW CONCEPT IN CHEMISTRY TEACHING: GREEN CHEMISTRY

Teaching Introductory Chemistry using Concept Development

Green chemistry

Since their initial appearance in the scientific literature, the terms "green" and "sustainable" have been increasingly used and are nowadays ubiquitously present in the terminology of several research areas. The seminal origin of what is considered “green chemistry” today might be ascribed to the launch of the Responsible Care® initiative by the American Chemistry Council (ACC) [1] and to the ...

Green chemistry.

Gilbert's chemistry sets, those that many of today's practicing chemists received as children, proved to be the spark that ignited many a lifelong exploration of the wonders of chemistry. While DuPont was espousing its contributions to the world with its motto, "Better living through chemistry," children were using the popular Gilbert's chemistry sets to perform the simplest experiments and vie...

Green Chemistry Metrics with Special Reference to Green Analytical Chemistry.

The concept of green chemistry is widely recognized in chemical laboratories. To properly measure an environmental impact of chemical processes, dedicated assessment tools are required. This paper summarizes the current state of knowledge in the field of development of green chemistry and green analytical chemistry metrics. The diverse methods used for evaluation of the greenness of organic syn...

Two-state reactivity as a new concept in organometallic chemistry.

It is proposed that spin-crossing effects can dramatically affect reaction mechanisms, rate constants, branching ratios, and temperature behaviors of organometallic transformations. This phenomenon is termed two-state reactivity (TSR) and involves participation of spin inversion in the rate-determining step. While the present analysis is based on studies of transition metals under idealized con...
