Riddle of Cement's Structure is Finally Solved
From MIT News:
Concrete is the world’s most widely used construction material, so abundant that its production is one of the leading sources of greenhouse gas emissions. Yet answers to some fundamental questions about the microscopic structure and behavior of this ubiquitous material have remained elusive.
Concrete forms through the solidification of a mixture of water, gravel, sand, and cement powder. Is the resulting glue material (known as cement hydrate, CSH) a continuous solid, like metal or stone, or is it an aggregate of small particles...
... Roland Pellenq, a senior research scientist in MIT’s department of civil and environmental engineering, director of the MIT-CNRS lab 2 hosted by the MIT Energy Initiative, and a co-author of the new paper, says the work builds on previous research he conducted with others at the Concrete Sustainability Hub (CSHub) through a collaboration between MIT and the CNRS. “We did the first atomic-scale model” of the structure of concrete, he says, but questions still remained about the larger, mesoscale structure, on scales of a few hundred nanometers. The new work addresses some of those remaining uncertainties, he says. ( full article )
Who Is Adopting IoT and Why?
We all know the Internet of Things is set to revolutionize the manufacturing industry but how will this happen? A new study of manufacturers across 12 different countries has provided quantified answers to the questions the industry is asking.
Three Reasons Why Advanced Manufacturing Institutes Matter
American manufacturing is surging with almost 900,000 new jobs created in the past six years. While thats incredible progress, how do we take manufacturing to the next level?
Industry 4.0: What businesses need to know
By Barclay Ballard for ITProPortal: In order for businesses to prepare for Industry 4.0, they first need to understand the technological driving forces behind it, including the Internet of Things. Although mainstream examples of IoT devices are relatively limited at the moment, in the future connected objects are expected to revolutionise a whole host of business sectors. In the same way that new manufacturing processes brought about huge upheaval during the Industrial Revolution, the Internet of Things is also predicted to bring wholesale changes to industry.
“The Industrial Internet of Things (IIoT) has been described as a crucial step in the Fourth Industrial Revolution or Industry 4.0,” explains Martyn Williams, managing director of industrial automation software expert, COPA-DATA UK. “Using IoT technology, organisations are developing smarter infrastructures and building connected networks across entire manufacturing processes.”
Some of the key changes predicted to emerge as the Internet of Things is adopted by industrial firms include the following: Cont'd...
Four Points You Need to Consider when Thinking About Automating or Robotizing Your Operations
If your products have regular and stable characteristics, hard automation makes sense. If however each product is different, flexible automation or robotics should be favored.
Japan Embracing Industry 4.0 And IoT To Leap Into Next Industrial Automation
The challenge ahead is that not only manufacturing technologies will change drastically but the whole business environment, in which Japan may have to strive to overcome other than IoT super next generation automation.
UK 'risks losing out in Industry 4.0 race'
By PRW: A leading trade body has warned that a lack of government planning was threatening the UK’s position at the forefront of Industry 4.0, also known as the fourth industrial revolution.
A number of plastics companies in the UK and on the Continent have begun to develop products and processes that take into account developments in and around Industry 4.0 – also known as the ‘Internet of Things’.
However research conducted by manufacturers’ organisation the EEF found that while 91% of companies surveyed believed that internet access was as important to their business as electricity and water supplies more than half reckoned connectivity was inadequate for the future.
While the awareness of how important the internet was to a company’s operation was seen as a positive, the EEF highlighted that poor digital connectivity may prove to become a drag on future growth.
Many companies were already having to pay a premium to ensure they had high-speed access, the trade body said. Cont'd...
Buildings Manufactured From A 3D Printer
With the flexibility of construction, 3D buildings will allow architects to dream up all sorts of extraordinary edifices that would be too difficult or too expensive to build, using traditional methods. A 3D-printed building would not need to coincide with our traditional ideas of what a building looks like.
Smart Factories Need Smart Machines
Industry 4.0 Smart Factories and Smart Machines continue to drive dramatic efficiency improvements across the supply chain, within the factory and inside machines.
3D printing software, sensors, and carbon nanotubes among top Advanced Materials trends of 2016

Three Things to Do Before Operating Your New Automated Equipment
Youre getting impatient to turn the main switch "on" to benefit from the enhanced productivity that it will give you. Before doing that, we recommend a few actions that should be completed before running at full production speed.
Boy, do Fanuc and Cisco have a deal for your factory
Fanuc and Cisco Systems are set to commercialize a technology this summer that promises glitch- and disruption-free factory operations. The Internet of Things-based system monitors machinery and spots signs of possible abnormalities so that parts can be replaced more smoothly and without affecting operations.
A one-minute suspension at a car factory generally costs around 2 million yen ($16,900). If, for example, a gear breaks and operations are halted for 60 minutes to replace it, the costs would be 120 million yen. Frequent line stoppages could also affect product quality.
The Fanuc-Cisco system uses sensors attached to each robot carrying or welding parts to monitor temperatures, vibration and other conditions. Data streams are sent via the Internet. A computer analyzes the data and decides which parts will likely need fixing and when. The system also places orders for replacements. The accuracy of the system's prediction and analysis functions will increase as data accumulates, representatives from the companies said. Cont'd...
Is Velo3D Plotting a 3-D Printed Robot Revolution?
Tekla S. Perry for IEEE Spectrum: Velo3D, based in Santa Clara, Calif., has $22.1 million in venture investment to do something in 3-D printing: That makes it fourth among 2015’s best-funded stealth-mode tech companies in the United States, according to CB Insights. This dollar number is about all the hard news that has come out of this startup, founded in 2014 by Benyamin Butler and Erel Milshtein. But job postings, talks at conferences, and other breadcrumbs left along Velo3D's development trail—has created a sketchy outline of this company’s plans.
Consider which 3-D printing technology is ready for disruption: metal. 3-D printing of plastics took off after 2009, when a key patent that covered the deposition technology expired; we now have desktop printers for 3-D plastic objects as cheap as $350. Printing of metal objects—done regularly in industry, particularly aerospace—uses a different, and, to date, far more expensive technology: selective laser sintering. This technology melts metal powders into solid shapes; it requires high temperatures, and far more complicated equipment than what’s found in the layering sort of printers used for plastic. The patent for this technology expired in early 2014—just before the formation of Velo3D. At the time, industry experts indicated that there wouldn’t be cheap metal printers coming anytime soon, but rather, would only come after “a significant breakthrough on the materials side,” OpenSLS’s Andreas Bastian told GigaOm in 2014. Could Velo3D’s founders have that breakthrough figured out? Cont'd...
