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 )

Scott J Grunewald for 3DPrint.com: A team of engineers from the University of Bristol — comprising Thomas M. Llewellyn-Jones, Bruce W. Drinkwater and Richard S. Trask — have developed a new hybrid type of 3D printing that can both assemble and print with composite materials using a combination of desktop 3D printer technology, light-curable resins and ultrasonic waves. This new process can allow super strong and lightweight composites like the variety used to produce tennis rackets, golf clubs, professional bicycles or even airplane parts to be used with additive manufacturing technology. Needless to say these new material options will offer entire new industries the ability to incorporate 3D printing into their manufacturing workflow. And the best part is that for the most part the process was made using existing 3D printing technology. Composite materials are made by combining micro-structures of glass or carbon fibers with a plastic material. The carefully arranged fibers lock together and give the new material its strength and durability, while the plastic ensures that the resulting material will be lightweight. Currently, composite materials are manufactured as thin sheets that are then layered and cut into the desired shape and thickness. The problem with using this as a 3D printing material is the small fibers in the composite materials. In order to produce the desired strength the fibers need to be aligned in a very precise structure, which is currently not possible to reproduce using a 3D printer. Cont'd.. .
From Hanchen Huang of Northeastern University: MesoGlue is our revolutionary joining solution that lets you attach items together with a metal bond, at room temperature. This is like welding or soldering, but without the heat! The patented process gives you the strength and thermal/electrical conductance of a metal bond, with the ease of attachment of glue or tape. Surfaces are merely pressed together to form a very strong connection. Our MesoGlue technology can be applied to nearly any flat surface. The surface can be rigid or flexible, and roll-to-roll processing is possible. We currently offer coating of two joining surfaces at our state of the art processing facility. Items of up to approximately 1 cubic foot can be accommodated. MesoGlue Silver: A pure silver bond offering the highest electrical and thermal conductivity. Formation of the bond requires moderate pressure. MesoGlue Eutectic: A bond made of primarily copper with other metals added to help the process. Formation of the bond requires only fingertip pressure. (MesoGlue Homepage)
by Zacks Equity Research: Technology giant and Dow component Cisco Systems, Inc. recently entered into a strategic alliance with a robotics company Fanuc America, thereby stepping up its efforts to make itself a key player in the Internet of Things (IoT) space. Per the alliance, Fanuc and Cisco have built an IoT system that enables Fanuc to monitor every robot on the factory floor. This way it can be determined whether a robot is likely to fail, so that a service technician can fix the equipment before it stops working. This could save companies hundreds of dollars of fixing cost. Per Cisco CEO Chuck Robbins, downtime for these robots can cost a business $16,000 per minute. Therefore, the new system that offers predictive maintenance can be a big thing for some operations. The companies are currently testing the system in a channel that comprises around 1,800 robots and includes Fanuc customer, GM. In this testing period, Fanuc says its customer has saved $38 million. Fanus has plans to expand the system to 2,500 robots by the end of the year. Cont'd...
BY GERRY SHIH for Reuters: In a cavernous showroom on the outskirts of this port city in northeastern China, softly whirring lathes and svelte robot arms represent Dalian Machine Tools Group's (DMTG) vision of an automated future for Chinese manufacturing. On closer inspection, however, most of the machines' control panels bear the logos of Japan's FANUC Corp or the German conglomerate Siemens. The imported control systems in DMTG's products – used in the assembly of everything from smartphones to cement trucks – are symbolic of the technology gap between Chinese and foreign industrial automation firms, just one of several challenges facing China's ambition to nurture a national robotics industry. Chinese robotics firms are also grappling with a weakening economy and slumping automotive sector, and industry insiders already predict a market bubble just three years after the central government issued policies to spur robotics development. "Last year everybody thought they could produce a robot," said Alan Lee, director of Asia sales and business development at Boston-based Rethink Robotics. "When you have market saturation you'll have filtering and M&A. These guys will be the first layer to suffer." It is a storyline familiar from other new industries such as solar panels: Beijing's policies and subsides trigger a wave of low-margin, low-cost contenders to rush into the market, where, with no meaningful technology of their own, they struggle to compete on price alone.

by Patrick Davison, Director of Standards Development, Robotic Industries Association: Last week, an unfortunate fatality involving an industrial robot and a worker occurred at a Volkswagen plant in Baunatal, Germany. The Robotic Industries Association (RIA) and its member companies express its deepest sympathies to the victim’s family, friends, and colleagues. According to news sources, the worker was part of a contracting crew responsible for setting up the robot, and was working inside the safeguarded space when the incident occurred. A second member of the contracting crew was standing outside of the safeguarded space and was not harmed. The international media response to the incident was aggressive, swift, and expounded on topics that were not relevant to the incident. AWashington Post article referenced the dangers of Artificial Intelligence and posed the question, “Should the world kill killer robots before it’s too late?” In another story, a Financial Times journalist with a name similar to a popular character in The Terminator franchise started a social media frenzy with a tweet. A video from Ireland expounds on random tweets regarding the incident with backdrop footage of the Honda ASIMO robot and manual automotive operations. Also, according to this article on an automotive news and gossip site, a Times of India article posted a photo of a gun-wielding toy robot beside the story. Cont'd...
