Build up of the graphene materials industry has progressed a bit more slowly than originally expected a decade ago as scientists and engineers peered through their electron microscopes at single atoms of carbon and counted their many attributes.  At the time the potential to improve performance in end products like metal alloys and electronics seemed limitless.   Unfortunately, reality has not imitated early dreams.  Those companies that have brought graphene to the commercial market will attest to the challenges of jumping off the laboratory bench and into a factory. Even more frustrating is the sourcing of graphene to use in research, product development and...

by Debra Fiakas, CFA The post “Water:  Invisible Crisis” introduced a new series on water supply in Latin America, describing the lack of access to quality water despite a bountiful supply of rainfall and snow melt.  As the series has unfolded we have learned that water supply in Latin America is largely a local government undertaking.  Investment opportunities are limited to water management companies that sign on to operate government-owned infrastructure or water treatment solution providers. Water supply to the north has inched further into the commercial realm.  A discussion of water investment would not be completed without a look at private water suppliers in the...

Graphene is a one-atom thick sheet of carbon atom arranged in a honeycomb lattice.  It is an exceptional conductor of heat and electricity and its strength is unparalleled.  Although synthetic graphite can be used to produce graphene and it offers the benefit of consistency, natural graphite is far less expensive as a source material.  Synthetic graphite is made by combining petroleum coke with carbon black in a high heat process that burns up profits as it purifies the carbon. There are several methods for producing graphene.  Exfoliation of natural graphite is perhaps the most common alternative because it produces the least defects and leaves...
