Scientists at Australian research centre CSIRO have used graphene to create a simple filtration system that could change the lives of millions in the developing world by making the process of purifying water faster and more effective. Read more
Among graphene's long list of superpowers, filtering water may be one of the most directly beneficial. Now a team of Australian scientists has demonstrated how effective a specially-designed form of graphene can be at purifying water with a pretty challenging test: the filter made water from Sydney Harbour safe to drink in one step...Continue Reading Graphene filter makes even Sydney Harbour
A Canon patent from October, 2017 resurfaced on the Canon rumor mill today, and it describes something pretty innovative from the Japanese camera giant. The patent shows a lens adapter—ostensibly designed for a mirrorless camera—that features a built-in variable-voltage ND filter.The ND filter component is "formed from an electrochromic device [or a liquid crystal element] which changes light tra
Aurora Aperture has just introduced a very interesting little piece of photography gear: the world's first variable graduated neutral density filter. Variable NDs are fairly common, as are graduated NDs, but until now nobody had thought to (or at least managed to) mix the two ideas into one.Enter the Aurora PowerGXND: a variable hard transition graduated neutral density filter with continuously v
