Little to Protect Persian Gulf Construction Workers
Nearly all the workers come from other countries, drawn by plentiful work in recent years due to the fast pace, high volume and large scale of construction on some of the world’s tallest skyscrapers.
Campus Heated with Vegetable Oil Waste
The college says the waste vegetable oil, with renewable energy incentives, is available at a cost that is comparable to that of the fuel previously used to meet all of its heating needs.
Fine-Grained Microstructure Could Toughen Coatings
If chromium nitride-based coatings are made with very fine grains, the force required to deform such materials increases dramatically.
Energy-Related CO2 Emissions Low
EIA attributes the decline to mild weather, a changing fossil fuel mix and increasing renewable energy consumption.
Cellulosic Jet Fuel for Use on Commercial Flights
The company has adapted its processes for converting cellulosic sugars derived from wood waste into renewable isobutanol to produce alcohol-to-jet fuel.
3D-Printed Elastomer Could Support Flexible Electronics
Traditional 3D printing is typically associated with rigid plastic structures made of polylactic acid or acrylonitrile butadiene styrene, created one thin layer at a time.
Wave Splash Model Could Improve Seawall Design
Use of the model could help inform the design of seawalls that, until now, have not taken into account the pattern of spray produced by waves.
Wirelessly Powered Drone Technology Demonstrated
The technology uses inductive coupling, a concept initially demonstrated by inventor Nikola Tesla over a century ago.
With Chicken Litter, Sometimes Less Is More
A new study by the USDA Agricultural Research Service has calculated how much chicken litter farmers need to apply to cotton crops to maximize profits.
Marine Squadron Tests 3-D Printing for Possible Field Use
The working group agreed on a Humvee door handle, since the handles that come with the vehicles tend to break easily, and a door handle would be a relatively low-risk vehicle part to start with.
New System Leads to Shorter Production Times
Aztalan took four machines that were used for long-term production runs and combined them into a dedicated short-run rapid prototyping cell.
Data Centers Cause Buildings' Electricity Use to Spiral
Cooling electricity intensity in buildings with data centers was found to be almost double that of other buildings in both the smallest and largest categories of office buildings surveyed.
Common Drugs Could Damage Aquatic Environments
Although studies of pharmaceuticals in surface waters have been carried out for several decades, there remains little systematic understanding of their transport, fate and impact.
Chemical Record of Fish Could Help Fight Food Fraud
Chemical tests were able to accurately link scallops and herring to their true locations and could be used to test if the chemical composition of an animal matches a claimed area of origin.
CellPod Grows Fresh Food in Your Kitchen
The idea of the CellPod concept is based on growing the undifferentiated cells of a plant rather than a whole plant.
Bacteria Could Make Nuclear Waste Repositories Safer
Researchers discovered a microbial community that lives hundreds of meters underground in the very rock layers that have been chosen to host Swiss nuclear waste.
Using Big Data to Solve Bus Woes in Brazil
The system incorporates analysis of two years of data from the Fortaleza bus system, used by an estimated 90% of the city's 3 million residents, who collectively take 30 million trips a month.
A Nontoxic Alternative to Ship Antifouling Paint?
Current antifouling coatings function by releasing biocidal copper, essentially killing everything in the waters around a ship.
Smartwatch Prototype Uses Wrist as a Joystick
The device provides a method for one-handed continuous gestural input for smartwatches.
Mediterranean's First LNG Passenger Ferry
Compared to standard marine diesel fuel, the LNG solution will reduce CO2 emissions by 25%, nitrogen oxide emissions by 85% and sulfur and particulate matter almost entirely.
