Navy developing ship coatings to reduce fuel, energy costs — ScienceDaily

It can repel water, oil, alcohol and even peanut butter. And it might save the U.S. Navy millions of dollars in ship fuel costs, reduce the amount of energy that vessels consume and improve operational efficiency. The Office of Naval Research (ONR) is sponsoring work by Dr. Anish Tuteja, an associate professor of materials science and engineering at the University of Michigan, to develop a new type of “omniphobic” coating. This chemical coating is clear, durable, can be applied to…

A promising new material has the right properties to capture solar energy and split water into hydrogen and oxygen — ScienceDaily

Solar energy is clean and abundant. But when the sun isn’t shining, you must store the energy in batteries or through a process called photocatalysis — in which solar energy is used to make fuels. In photocatalytic water splitting, sunlight separates water into hydrogen and oxygen. The hydrogen and oxygen can then be recombined in a fuel cell to release energy. Now, a new class of materials — halide double perovskites — may have just the right properties to split…

The End of Video Coding? – Netflix TechBlog – Medium

In the IEEE Signal Processing Magazine issue November 2006 article “Future of Video Coding and Transmission” Prof. Edward Delp started by asking the panelists “Is video coding dead? Some feel that, with the higher coding efficiency of the H.264/MPEG-4 . . . perhaps there is not much more to do. I must admit that I have heard this compression is dead argument at least four times since I started working in image and video coding in 1976.” People were postulating that video coding…

Electrons take one step forward without two steps back — ScienceDaily

Researchers at the University of California, Riverside, have, for the first time, successfully used electric dipoles to completely suppress electron transfer in one direction while accelerating in the other. The discovery could aid development of improved solar cells and other energy-conversion devices and hasten the design of new and superb energy and electronic materials. It is not a stretch to say that life depends on strictly regulated electron transfer. Electron transfer is among the most fundamental processes for sustaining life…

E. coli tailored to convert plants into renewable chemicals — ScienceDaily

What does jet fuel have in common with pantyhose and plastic soda bottles? They’re all products currently derived from petroleum. Sandia National Laboratories scientists have demonstrated a new technology based on bioengineered bacteria that could make it economically feasible to produce all three from renewable plant sources. Economically and efficiently converting tough plant matter, called lignin, has long been a stumbling block for wider use of the energy source and making it cost competitive. Piecing together mechanisms from other known…

Ultrasound scans for damage to concrete bridges

Credit: Phillipe Olivier The concrete Pantheon in Rome is in excellent condition after 2,000 years. Steel reinforcement can dramatically reduce lifespan of concrete structures however and deterioration can begin after only 10 years. Infrastructures such as bridges and roads are usually reinforced concrete, which need continuous monitoring for regular operation and safety. Large concrete structures pose various challenges mainly due to the wide range of aggregates, fragments compacted together, in the material. ‘On a roll’—non-destructive testing (NDT using ultrasound…

Project Jengo Celebrates One Year Anniversary by Releasing Prior Art

Today marks the one year anniversary of Project Jengo, a crowdsourced search for prior art that Cloudflare created and funded in response to the actions of Blackbird Technologies, a notorious patent troll. Blackbird has filed more than one hundred lawsuits asserting dormant patents without engaging in any innovative or commercial activities of its own. In homage to the typical anniversary cliché, we are taking this opportunity to reflect on the last year and confirm that we’re still going strong. Project…

How automation will make oil rigs safer

Automation could help us avoid future disasters. Credit: US Coast Guard Offshore oil rigs can be extremely dangerous places to work. Over the last few decades, several offshore explosions have led to environmental disasters and the death of workers. Regulations have so far failed to stop fatal accidents from occurring. But with developments in technology, particularly the rise of automation, we’re hoping that future accidents can be reduced. Small offshore rigs are the subject of research for automated monitoring systems,…

One of North America’s rarest bees has its known range greatly expanded — ScienceDaily

The Macropis Cuckoo Bee is one of the rarest bees in North America, partly because of its specialized ecological associations. It is a nest parasite of oil-collecting bees of the genus Macropis which, in turn, are dependent on oil-producing flowers of the genus Lysimachia. In fact, the cuckoo bee — which much like its feather-bearing counterpart does not build a nest of its own, but lays its eggs in those of other species instead — is so rare that it…

Documentation Details Matter – Square Corner Blog – Medium

Not too long ago I joined the Developer Platform team at Square as a product designer. One of the first things I was tasked with was addressing some quick-hit, tactical improvements we could make to our existing site to improve the developer experience. A designer on a developer team? Working on documentation? “Oil and water,” you might say, but quite the opposite. I’ve waded through my fair share of documentation, Stack Overflow posts, and random blogs, teaching myself various languages…
