Graphene Key to High-Density, Energy-Efficient Memory Chips
Graphene's electrical, thermal and atomically thin properties can be used to create more energy-efficient data storage.
Using Nanotechnology to Boost Capacitors' Energy Density
Key to the success of the capacitor is its interdigitated design, which decreases the distance between opposing electrodes and increases the capacitor's ability to store an electrical charge.
Engineering for the Developing World: Meeting Market Demand
Jodie Wu noticed something when she demonstrated the pedal-powered thresher for villagers: they were more interested in her solar-powered light.
Inspections Are Critical for High Energy Piping Safety
Temperature change causes a 100-yard-long pipe to expand by some 30 inches. Imagine if this pipe was not being permitted to expand or contract freely.
Sticky Hydrogel May Have Health, Marine Applications
Researchers applied a square of hydrogel between two plates of glass, from which they suspended a 55-lb. weight.
Pop-Up Sensor May Help Robotic Surgery
Inspired by origami, pop-up manufacturing fabricates micromachines by layering laser-cut materials into thin, flat plates that pop up into complete electromechanical devices.
Technology Could Make Aircraft and Ships Stealthier
Conventional radar absorbers are usually too thick or have too narrow an absorption bandwidth to cloak objects in the ultra-high-frequency regime.
Printer Generates PCB Prototypes
Voltera V-One uses rapid prototyping principles to turn design files into prototype boards.
NASA Robots Go to School for Reprogramming
Valkyrie is intended to be a semi-autonomous robot that can execute complex tasks in dangerous, degraded, human-engineered environments.
Filterless Water Desalination Achieved with Shock Electrodialysis
Researchers use water flowing through low-cost porous media, which could be relatively easy to scale up for desalination or water purification.
NREL Estimates Economically Viable U.S. Renewable Generation
NREL analysts say that at 2014 costs, renewable energy technologies combine for 820 terawatt-hours of estimated economic potential, nearly 20% of the U.S. annual electricity generation from all sources.
Fundamentals of Cooling Tower Heat Transfer – Part 3
Microbiological growth can cause the most prompt, intense fouling in cooling systems as the warm and wet environment is ideal for “bug” growth.
Managing the Data Deluge for National Security Analysts
Research in cognitive science at Sandia will help design software and tools to help make trends easier to spot.
Designing Earthquake-Resistant Wood-Framed Buildings
Researchers will study how to combine the traditional light wood frame system of construction with the emerging cross-laminated timber method.
Storage Advance May Boost Solar Thermal Energy
In comparison to existing approaches, the researchers say, the new system could allow a 10-fold increase in energy density.
Strengthening Titanium Without Sacrificing Its Ductility
The material is as strong as small-grained titanium because a surrounding layer makes it difficult for larger grains to deform.
Rice Study Outlines Storm Defense for Houston Ship Channel
A hurricane with winds 15% stronger than Hurricane Ike (2008) and making landfall on the southwestern tip of Galveston Island could result in a major environmental disaster.
Precast Concrete Could Enable Taller Wind Turbine Towers
Hexcrete can be stacked to form towers that capture winds that prevail 100 meters high.
GE Turboprop Engine to Be Manufactured in Europe
The engine has been selected by Textron Aviation to power a single-engine turboprop aircraft.
Kia to Include Autonomous Driving Tech by 2020
Automaker to invest $2 billion by 2018 to develop ADAS technologies.
