A Columbia Engineering research team has invented a prototype video camera that is the first to be fully self-powered: It can produce an image each second, indefinitely, of a well-lit indoor scene. They designed a pixel that can not only measure incident light but also convert the incident light into electric power.
The mesh coating is among a suite of nature-inspired nanotechnologies under development at Ohio State and described in two papers in Nature Scientific Reports. Potential applications range from cleaning oil spills to tracking oil deposits underground.
Imagine having your MRI results sent directly to your phone, with no concern over the security of your private health data. Or knowing your financial information was safe on a server halfway around the world. Or sending highly sensitive business correspondence, without worrying that it would fall into the wrong hands.
Additive manufacturing has been called a game changer. But new games require new instructions, and the manuals for a growing assortment of methods for building parts and products layer-by-layer, collectively known as "3D printing", still are works in progress. Manufacturing researchers at NIST have scoped out the missing sections in current guidelines for powder bed fusion, the chief method for "printing" metal parts.
More than 50 years ago, when the laser was a mere five years old, laser physicists dreamed of the development of an x-ray laser to expand the frontier of knowledge. The concept goes back to the mid-1960s, when scientists realized that laser beams amplified with ions would have much shorter wavelengths than beams amplified with gas.
Few among us may know what magnetic domains are, but we make use of them daily when we email files, post images or download music or video to our personal devices. Now a team of researchers at Lawrence Berkeley National Laboratory has found a new way of manipulating the walls that define these magnetic domains and the results could one day revolutionize the electronics industry.
Flexibility is critical when considering the future of science, research and lab environments. However, research needs down the road are difficult to predict, and flexibility is hard to define. Yet, reducing a facility’s flexibility may mean the loss of spare engineering capacities/infrastructures, services planning and space for anticipated growth and fit-out.
Most recent advances in artificial intelligence are the result of machine learning, in which computers are turned loose on huge data sets to look for patterns. To make machine-learning applications easier to build, computer scientists have begun developing so-called probabilistic programming languages, which let researchers mix and match machine-learning techniques that have worked well in other contexts.
A Univ. of New South Wales-led research team has encoded quantum information in silicon using simple electrical pulses for the first time, bringing the construction of affordable large-scale quantum computers one step closer to reality. The team has successfully realized a new control method for future quantum computers.
Univ. of Michigan scientists and students will build components of a giant camera that will map 30 million galaxies' worth of the universe in three dimensions. The camera is officially known as the Dark Energy Spectroscopic Instrument, abbreviated DESI, and it's designed to help answer one of the most puzzling scientific questions of our time: Why is the expansion of the universe accelerating?
You’re going to have to think very small to understand something that has the potential to be very big. A team of researchers developed a material that acts as a superhighway for ions. The material could make batteries more powerful, change how gaseous fuel is turned into liquid fuel and help power plants burn coal and natural gas more efficiently.
A new device developed by Univ. of California, Los Angeles, engineers and doctors may eventually help scientists study the development of disease, enable them to capture improved images of the inside of cells and lead to other improvements in medical and biological research.
Science is evolving: It’s becoming more translational and multidisciplinary in nature. Just as science evolves, so do lab environments. Most lab environments are now designed to be more open and not just meant for one discipline—today, biologists may work next to chemists, or chemists work alongside physicists, and so on.
A vest that allows the profoundly deaf to “feel” and understand speech is under development by engineering students and their mentors at Rice Univ. and Baylor College of Medicine. Under the direction of neuroscientist David Eagleman, Rice students are refining a vest with dozens of embedded actuators that vibrate in specific patterns to represent words. The vest responds to input from a phone app that isolates speech from ambient sound.
When MIT senior Emma Nelson was teaching engineering classes in China in 2013, a male student remarked of her as an instructor, “I thought we were supposed to meet engineers, not women.” As she stared out at the 100 college students before her, Nelson noticed there was just one female face looking back at her.
Light is an extremely useful tool for quantum communication, but it has one major disadvantage: it usually travels at the speed of light and cannot be kept in place. A team of scientists at the Vienna Univ. of Technology has now demonstrated that this problem can be solved—not only in strange, unusual quantum systems, but in the glass fiber networks we are already using today.
Now that most consumers download and stream their movies and music, more and more CDs and DVDs will end up in landfills or be recycled. But soon these discarded discs could take on a different role: curbing the release of greenhouse gases. In ACS Sustainable Chemistry & Engineering, scientists report a way to turn the discs into a material that can capture carbon dioxide, a key greenhouse gas, and other compounds
To design the next generation of optical devices, ranging from efficient solar panels to LEDs to optical transistors, engineers will need a 3-D image depicting how light interacts with these objects on the nanoscale. Unfortunately, the physics of light has thrown up a roadblock in traditional imaging techniques: The smaller the object, the lower the image's resolution in 3-D.
A great deal of public attention in the past couple of years has been showered on complexes of bacterial proteins known as “CRISPR-Cas” for their potential use as a tool for editing DNA. Now, researchers with the Lawrence Berkeley National Laboratory are reporting that CRISPR-Cas complexes could also serve as an engineering tool for RNA, the molecule that translates DNA’s genetic instructions into the production of proteins.
New research shows how inkjet-printing technology can be used to mass-produce electronic circuits made of liquid-metal alloys for "soft robots" and flexible electronics. Elastic technologies could make possible a new class of pliable robots and stretchable garments that people might wear to interact with computers or for therapeutic purposes.
Consumers are one step closer to benefiting from packaging that could give simple text warnings when food is contaminated with deadly pathogens like E. coli and Salmonella, and patients could soon receive real-time diagnoses of infections such as C. difficile right in their doctors' offices, saving critical time and trips to the lab.
Sometimes just reading about great lab and building design isn’t enough. Beauty is in the eye of the beholder, and the annual Laboratory Design Conference allows our attendees to view some of the most sexy, most well-planned and most sustainable labs there are in the host city.
Conduction and thermal radiation are two ways in which heat is transferred from one object to another: Conduction is the process by which heat flows between objects in physical contact, such as a pot of tea on a hot stove, while thermal radiation describes heat flow across large distances, such as heat emitted by the sun. These two fundamental heat-transfer processes explain how energy moves across microscopic and macroscopic distances.
Separating circulating cancer cells from blood cells for diagnostic, prognostic and treatment purposes may become much easier using an acoustic separation method and an inexpensive, disposable chip, according to a team of engineers from Penn State Univ.
Researchers are always searching for improved technologies, but the most efficient computer possible already exists. It can learn and adapt without needing to be programmed or updated. It has nearly limitless memory, is difficult to crash, and works at extremely fast speeds. It’s not a Mac or a PC; it’s the human brain. And scientists around the world want to mimic its abilities.
