Advanced plasma-based etching is a key enabler of Moore's Law that observes that the number of transistors on integrated circuits doubles nearly every two years. It is the plasma's ability to reproduce fine patterns on silicon that makes this scaling possible and has made plasma sources ubiquitous in microchip manufacturing.
Invisibility cloaking is no longer the stuff of science fiction: two researchers in The Edward S. Rogers Sr. Department of Electrical & Computer Engineering have demonstrated an effective invisibility cloak that is thin, scalable and adaptive to different types and sizes of objects.
With the rise of online open course platforms such as Khan Academy, MIT OpenCourseWare and iTunes U, it has never been easier to teach yourself everything from American history to semiconductor manufacturing. These courses enable students to advance at their own pace while accessing the limitless resources available on the internet for supplemental material.
When the Mars Atmosphere and Volatile Evolution Mission launches in November to study why the Red Planet is losing its atmosphere, one of its instruments will look to electrically charged particles called electrons for answers.
As scientists develop the next wave of smartwatches and other wearable computing, they might want to continue focusing their attention on the arms and the wrists. According to a recent Georgia Tech study, portable electronic devices placed on the collar, torso, waist or pants may cause awkwardness, embarrassment or strange looks.
Tiny self-assembling transport networks, powered by nano-scale motors and controlled by DNA, have been developed by scientists at Oxford University and Warwick University. The system can construct its own network of tracks spanning tens of micrometres in length, transport cargo across the network and even dismantle the tracks.
OLEDs are already used in the displays of smart phones or digital cameras today. They offer an especially bright image with high contrast, but come with a serious drawback: typically, only one quarter of the electrical energy invested in running the device is actually converted into light.
Using inexpensive materials configured and tuned to capture microwave signals, researchers at Duke University's Pratt School of Engineering have designed a power-harvesting device with efficiency similar to that of modern solar panels.
Would-be donors skip giving when offered the chance to show public support for charities in social media, a new study from the University of British Columbia's Sauder School of Business finds.
Researchers have created a mechanism whereby human waste can be digested by microbes leading to a process of generating power from electricity. The first test involved using urine in microbial fuel cells to charge a mobile phone.
Solid Concpets, a Texas based 3D printing services company, has a Federal Firearms License (FFL) and legitimacy. Based on over 30 printed components, its 3D printed gun has fired 50 rounds in tests.
Carnegie Mellon University computer scientists have developed a new password system that incorporates inkblots to provide an extra measure of protection when, as so often occurs, lists of passwords get stolen from websites.
Tricking algae's biological clock to remain in its daytime setting can dramatically boost the amount of valuable compounds that these simple marine plants can produce when they are grown in constant light.
In research meant to highlight how the destruction of the Amazon rainforest could affect climate elsewhere, Princeton University-led researchers report that the total deforestation of the Amazon may significantly reduce rain and snowfall in the western United States, resulting in water and food shortages, and a greater risk of forest fires.
Researchers from Georgia Tech, the University of Tokyo and Microsoft Research have developed a novel method to rapidly and cheaply make electrical circuits by printing them with commodity inkjet printers and off-the-shelf materials. For about $300 in equipment costs, anyone can produce working electrical circuits in the 60 seconds it takes to print them.
Physicists at the National Institute of Standards and Technology (NIST) have demonstrated a compact atomic clock design that relies on cold rubidium atoms instead of the usual hot atoms, a switch that promises improved precision and stability.
Using the world's most brilliant X-ray source, scientists have for the first time peered into molten magma at conditions of the deep Earth mantle. The analysis at DESY's light source PETRA III revealed that molten basalt changes its structure when exposed to pressure of up to 60 gigapascals (GPa), corresponding to a depth of about 1400 kilometres below the surface.
A breakthrough in quantum cryptography demonstrates that information can be encrypted and then decrypted with complete security using the combined power of quantum theory and relativity - allowing the sender to dictate the unveiling of coded information without any possibility of intrusion or manipulation.
Nitric oxide (NO) is one of the most important signaling molecules in living cells, carrying messages within the brain and coordinating immune system functions. In many cancerous cells, levels are perturbed, but very little is known about how NO behaves in both healthy and cancerous cells.
As transistors get smaller, they also become less reliable. So far, computer-chip designers have been able to work around that problem, but in the future, it could mean that computers stop improving at the rate we’ve come to expect.
