A Specifying Engineer’s Guide to Water Treatment
Project developers often do not fully understand the importance of water treatment and steam generation chemistry. Here’s what you need to know.
The Maker Revolution Gains Traction
The step toward individual fabrication represents something of a revolution that has the potential to rival earlier revolutions in digital communication and computation.
DOE to Explore Nuclear Waste Disposal at North Dakota Site
The test will provide insight into challenges such as drilling techniques, subsurface characterization and wellbore stability and sealing.
Partial Water Pipe Replacement Ups Health Risk: Study
If pipe replacements are to be done in response to lead contamination, half measures can create a greater problem than doing nothing, researchers say.
Sensors Counter Humidity-Caused Biofouling
Biofouling can impact the performance and service lifetimes of materials and devices that operate in high-humidity environments.
Fuel Cell Could Take on Aircraft Taxi Tasks
The hybrid plane concept uses a hydrogen fuel cell stowed in the aircraft's hold.
Public Exposed to High Ultrasound Levels, UK Researcher Says
The public is routinely exposed to VHF/US levels over 20 kHz in areas such as railway stations, museums, libraries, schools and sports stadiums.
Lower-Cost Solar Cells Without Doping
The study demonstrated a dopant-free silicon cell with an average efficiency above 19%.
Marine Worm Inspires Wet Glue
Sandcastle worms secrete an adhesive to build a tube reef in intertidal environments where wind and wave velocity often exceed 25 meters per second.
NIST Looks to Overcome Robots' Agility Limitations
Improving agility, so that robots can perform a diverse set of tasks and be re-tasked on the fly, would eliminate obstacles to wider adoption of automation by small and medium-size manufacturers.
Hydrogen Plasma Achieved in German Stellarator
The initial experimentation phase will last till mid-March.
GTI, Ricardo to Develop Low-NOx Natural Gas Engine Technologies
According to the California Air Resources Board, by 2031 the South Coast Basin will exceed mandatory air quality standards unless NOx emissions are reduced 90% from current levels.
3D-Printed Hypersonic Engine Combustor Successfully Tested
A scramjet combustor is one of the mission-critical components of the propulsion system, responsible for housing and maintaining stable combustion within an extremely volatile environment.
Dump Truck Design Increases Payload
The unit can increase payload capacity by up to 10 percent from older models.
A Rising Call for Responsible Artificial Intelligence
As AI becomes more sophisticated and embedded in society, researchers, tech leaders and governmental agencies are laying the groundwork for its responsible design and use.
Standing Up to the Perfect Storm
Place a 1/50th scale model in the test basin at the University of Maine, and engineers can simulate winds of more than 200 mph and waves as high as 115 ft.
Technique Takes the Blur Out of Digital Microscopy
The wavelength scanning approach uses a device that captures a stack of digital images, each with a slightly different wavelength of light.
Removing Landing Gear Raises UAVs' Payload, Uses
Ultralight solar-powered aircraft can fly at altitudes in excess of 20 kilometers and stay airborne for several weeks; weight is crucial for long-duration flights.
Bio-Inspired Self-Cleaning Window Is Developed
The window uses nanostructures that amplify the thermochromic properties of a coating applied to the glass to cut glare, save energy and enable self-cleaning.
Floating Wetland Treats Storm Runoff
The system uses plants to mitigate the impacts of stormwater runoff by drawing excess nutrients and pollutants from the surrounding water.
