Nanotechnology is viewed by those in favor of its development in two different ways, and the divide is not recent. This article describes the origins of the differing visions of nanotechnology and examines their broader impacts. The typical history of the field tells nothing about these differing visions, which perhaps misleads. At least two…

Organic v inorganic dichotomy in chemistry has begun to disappear while a new formal research discipline, bioinorganic chemistry, is emerging. The field has been developed with the realization that a third of all proteins and bioenzymes contain an inorganic element such as a metal critical to their chemical nature. (Author/RE)

Biodiesel was synthesized by transesterification of waste vegetable oil using common glassware and reagents, and characterized by measuring heat of combustion, cloud point, density and measuring the heat of combustion and density together allows the student the energy density of the fuel. Analyzing the biodiesel can serve as a challenging and…
