Researchers from Hokkaido University (Japan) have created 'fiber-reinforced soft composites' or tough hydrogels combined with woven fiber fabric. The study, 'Energy-Dissipative Matrices Enable Synergistic Toughening in Fabric Reinforced Soft Composites' (Authors - Yiwan Huang, Daniel R. King, Taolin Sun, Takayuki Nonoyama, Takayuki Kurokawa, Tasuku Nakajima, Jian Ping Gong), was recently published in Advanced Functional Materials. Researchers combined hydrogels containing high levels of water with glass fiber fabric to create bendable, yet tough materials, employing the same method used to produce reinforced plastics. They found that a combination of polyampholyte (PA) gels, a type of hydrogel they developed earlier, and glass fiber fabric with a single fiber measuring around 10µm in diameter produced a strong, tensile material. The procedure to make the material is simply to immerse the fabric in PA precursor solutions for polymerization. The developed fiber-reinforced hydrogels are 25 times tougher than glass fiber fabric, and 100 times tougher than hydrogels. Moreover, the newly developed hydrogels are 5 times tougher compared to carbon steel. According to lead researcher, Prof. Jian Ping Gong, 'The fiber-reinforced hydrogels, with a 40 percent water level, are environmentally friendly. The material has multiple potential applications because of its reliability, durability and flexibility. For example, in addition to fashion and manufacturing uses, it could be used as artificial ligaments and tendons, which are subject to strong load-bearing tensions.' Read on...

Society continues to face challenges to construct affordable, high-quality, innovative and future-focused built environments. Many building processes are sub-standard and obsolete, with sustainability concerns. Current research on integration of digital technologies within architectural and construction processes promises substantial contributions to sustainability and productivity. Research connections between diverse fields like architecture, structural design, computer science, materials science, control systems engineering, and robotics are required. Researchers during the American Association for the Advancement of Science (AAAS) 2017 reveal latest developments in digital fabrication in architecture at 1:1 building scale. They explain successful integration of digital technologies in design, planning, and building processes to transform the building industry. (1) On Site Digital Fabrication for Architecture: Prof. Jonas Buchli, Agile and Dexterous Robotics at ETH Zurich (Switzerland), proposes a radical focus on domain specific robotic technology enabling the use of digital fabrication directly on construction sites and in large scale prefabrication. (2) The New Mathematics of Making: Prof. Jane Burry, Director of the Spatial Information Architecture Laboratory at RMIT University in Melbourne (Australia), explores how these opportunities (Digital computation; Linking of design attributes to extraneous factors; Mathematical design models etc) for automation, optimization, variation, mass-customisation, and quality control can be fully realised in the built environment within full scale construction. (3) Building Materials for 3D Printing: Prof. Ronald Rael, Architecture at University of California at Berkeley (USA), reveals the development of new materials that can overcome the challenges of scale and costs of 3D printing on 1:1 construction scale. He demonstrates that viable solutions for 3D printing in architecture involve a material supply from sustainable resources, culled from waste streams or consideration of the efficiency of a building product's digital materiality.

Team of researchers from Massachusetts Institute of Technology (USA) (Markus Buehler, Zhao Qin, Gang Seob Jung, Min Jeong Kang), has designed one of the strongest lightweight materials known, by compressing and fusing flakes of graphene, a 2-dimensional form of carbon. The new material, a sponge-like configuration with just 5% the density of steel, can have a strength 10 times more. The findings, published in the journal 'Science Advances', show that critical factor of 3-D form is their unusual geometrical figure, suggesting that similar strong, lightweight materials can be made from other materials by creating similar geometric figures. 2-D materials have exceptional strength alongwith unique electrical proberties. But they are extraordinarily thin. Prof. Buehler says, 'They are not very useful for making 3-D materials that could be used in vehicles, buildings, or devices. What we've done is to realize the wish of translating these 2-D materials into 3-D structures.' Prof. Qin adds, 'Once we created these 3-D structures, we wanted to see what's the limit - what's the strongest possible material we can produce.' According to Prof. Buehler, 'You can replace the material itself with anything. The geometry is the dominant factor. It's something that has the potential to transfer to many things.' Prof. Huajian Gao of Brown University comments, 'This is an inspiring study on the mechanics of 3-D graphene assembly. The combination of computational modeling with 3-D-printing-based experiments used in this paper is a powerful new approach in engineering research. It is impressive to see the scaling laws initially derived from nanoscale simulations resurface in macroscale experiments under the help of 3-D printing. This study shows a promising direction of bringing the strength of 2-D materials and the power of material architecture design together.' Read on...

Gifts are an important tool for initiating and enhancing relationships, and it is often challenging to give just the right gift that connects well. According to Prof. Cassie Mogilner Holmes of University of California at Los Angles, 'What we found was that the recipient feels more connected to you as the gift giver after receiving an experiential gift rather than a material one.' Prof. Holmes is a social psychologist and marketing expert, and is a world's leading authority on consumer happiness. She says, 'Everbody wants to be happy. But we don't often know the best path towards that end. I am trying in my research to understand what are the ways we can think and behave that are most conducive to our happiness and well-being.' Prof. Holmes has been exploring the relationship between happiness, time and money for almost a decade. Her studies found that when your attention is drawn subconsciously to time, you are more motivated to engage with other people, and that will make you happier than if you were thinking about money. Prof. Holmes and her UCLA colleague, Prof. Hal Hershfield, posed the question of what people want more of - time or money - to thousands of Americans representing different ages, socio-economic levels, occupations, races and genders. According to her, 'We found that those who were more likely to choose having more time over having more money were happier.' She further explains that the psychology around these choices has less to do with age than with people's outlook on their futures and on time. She adds, 'Younger people who feel their time is expansive and that they have a very long future in front of them will enjoy greater happiness from extraordinary experiences. For older people who feel their time is limited and fleeting, they feel a need to savor the moment. These people extract happiness from even mundane, ordinary experiences, like having coffee with a friend.' Read on...

Research by Prof. Ali Besharat of University of Denver, 'The Effect of Review Valence and Variance on Product Evaluations: An Examination of Intrinsic and Extrinsic Cues' (Other authors - Ryan Langan of University of San Francisco; Sajeev Varki of University of South Florida), explores how the rating and variance in reviews affect the decision process. Researchers find that the nature of products, a product's brand, reviewers' credibility, and the structure of online customer reviews all significantly impact consumer decision-making and, subsequently, a company's bottom line in terms of sales. According to Prof. Besharat, 'In the case of high online review variance, we find that when brand equity is high - Nike for example - then reviewer credibility does not influence consumers' purchase intentions. But when a consensus among reviews exists (low variance), reviewer credibility emerges as a significant diagnostic cue.' Another research by Prof. Ana Babić Rosario of University of Denver, 'The Effect of Electronic Word of Mouth on Sales: A Meta-Analytic Review of Platform, Product and Metric Factors' (Other authors - Francesca Sotgiu of Vrije Universiteit Amsterdam; Kristine De Valck of HEC Paris; Tammo H.A. Bijmolt of University of Groningen), confirms Prof. Besharat's findings and demonstrates that a wide variance in consumer opinions has a detrimental effect on product sales. According to Prof. Rosario, 'The reason why variability of reviews can harm sales more than negativity is that electronic world of mouth, in theory, is a way for consumers to reduce risk and uncertainty, which does not happen when other consumers' feedback is highly inconsistent.' Prof. Rosario's findings should be of interest to product and platform managers, internet and social media monitoring agencies. Read on...

Researchers from Stanford University [Po-Chun Hsu, Alex Y. Song, Peter B. Catrysse, Chong Liu, Yucan Peng, Jin Xie, Shanhui Fan, Yi Cui] have developed a low-cost, plastic-based textile that, when woven into clothing, has the ability to keep the body cool more efficiently as compared to the natural or synthetic fabrics that are used today. The research was published in journal 'Science' titled, 'Radiative human body cooling by nanoporous polyethylene textile'. According to Prof. Yi Cui of Materials Science and Engineering, 'If you can cool the person rather than the building where they work or live, that will save energy.' The new material cools by letting perspiration evaporate through it, as fabrics normally do. But the other most innovative characteristic of the material's cooling mechanism is that it allows heat that the body emits as infrared radiation to pass through the plastic textile. Prof. Shanhui Fan of Electrical Engineering says, '40-60% of our body heat is dissipated as infrared radiation when we are sitting in an office. But until now there has been little or no research on designing the thermal radiation characteristics of textiles.' Researchers engineered the cooling material by blending nanotechnology photonics and chemistry to give polyethylene, the material used as kitchen wrap, a number of characteristics desirable in clothing material. It allows thermal radiation, air and water vapor to pass right through, and it is opaque to visible light. Prof. Cui says, 'If you want to make a textile, you have to be able to make huge volumes inexpensively.' According to Prof. Fan, 'This research opens up new avenues of inquiry to cool or heat things, passively, without the use of outside energy, by tuning materials to dissipate or trap infrared radiation.'

Multidisciplinary team of researchers lead by Prof. Amin Salehi-Khojin from University of Illinois at Chicago (UIC) have engineered a process through a solar cell to mimic plants' ability to convert carbon dioxide into fuel, a way to decrease the amounts of harmful gas in the atmosphere and produce clean energy. According to Prof. Salehi-Khojin, 'The artificial leaf essentially recycles carbon dioxide. And it's powered entirely by the sun, mimicking the real photosynthesis process. Real leaves use the energy from the sun and convert carbon dioxide to sugar. In the artificial leaf that we built, we use the sun and we convert CO2 to (synthetic gas), which can be converted to any hydrocarbon, like gasoline.' Describing the process Prof. Salehi-Khojin said, 'The energy of the sun rearranges the chemical bonds of the carbon dioxide. So the sun's energy is being stored in the form of chemical bonds, which can be burned as fuel...Scientists around the world have been studying carbon reduction, as this type of reaction is called, for years.' Prof. Nathan Lewis of California Institute of Technology, who has been studying solar fuels and artificial photosynthesis for more than 40 years, says, 'UIC's development is only a small piece of an eventual solar fuel product that can be widely implemented. There's a lot of steps that need to occur to envision how these things would translate into a commercializable system, but it's a step for building a piece of a full system that may be useful.' Prof. Michael R. Wasielewski of Northwestern University comments, 'UIC's development could push renewable energy technology forward.' The research, 'Nanostructured transition metal dichalcogenide electrocatalysts for CO2 reduction in ionic liquid', was recently published in journal 'Science'. UIC News Center website (news.uic.edu) provides the following information about co-authors and collaborators of this research - Amin Salehi-Khojin, Mohammad Asadi, Kibum Kim, Aditya Venkata Addepalli, Pedram Abbasi, Poya Yasaei, Amirhossein Behranginia, Bijandra Kumar and Jeremiah Abiade of UIC's Mechanical and Industrial Engineering Department, who performed the electrochemical experiments and prepared the catalyst; Robert F. Klie and Patrick Phillips of UIC's Physics Department, who performed electron microscopy and spectroscopy experiments; Larry A. Curtiss, Cong Liu and Peter Zapol of Argonne National Laboratory, who did Density Functional Theory calculations; Richard Haasch of the University of Illinois at Urbana-Champaign, who did ultraviolet photoelectron spectroscopy; José M. Cerrato of the University of New Mexico, who did elemental analysis. Read on...

Team of multidisciplinary researchers from Case Western Reserve University (USA) [Victoria Webster; Roger Quinn; Hillel Chiel; Ozan Akkus; Umut Gurkan; Emma L. Hawley; Jill M. Patel; Katherine J. Chapin], have created a 'biohybrid' robot by combining sea slug materials with 3D printed parts, that can crawl like sea turtle. Scientists suggest that in future, swarms of biohybrid robots could be released for such tasks as locating the source of a toxic leak in a pond that would send animals fleeing. They could also be used to search the ocean floor for a black box flight data recorder, a potentially long process that may leave current robots stilled with dead batteries. According to Ms. Webster, PhD student and lead researcher, 'We're building a living machine - a biohybrid robot that's not completely organic - yet. For the searching tasks, we want the robots to be compliant, to interact with the environment. One of the problems with traditional robotics, especially on the small scale, is that actuators - the units that provide movement - tend to be rigid.' Researchers also explain that if completely organic robots prove workable a swarm released at sea or in a pond or a remote piece of land, won't be much of a worry if they can't be recovered. They're likely to be inexpensive and won't pollute the location with metals and battery chemicals but be eaten or degrade into compost. Read on...

Prof. Henry Chesbrough of University of California at Berkeley, coined the term 'Open Innovation' in his book "Open Innovation: The New Imperative for Creating and Profiting from Technology" that was published on 2003. According to website OpenInnovation.net, 'Open Innovation is a paradigm that assumes that firms can and should use external ideas as well as internal ideas, and internal and external paths to market, as the firms look to advance their technology.' Organizations are now more commonly adopting open innovation. As Prof. Chesbrough suggested in his research few years ago that nearly 80% of organizations were already dabbling with open innovation in some form or other. In 2015, Carlos Moedas (European Union's Commissionar for Research, Science and Innovation), outlined the goals for his organization as 'Open Innovation, Open Science and Open to the World'. Recently EU published a paper to highlight its commitment to an open and transparent approach to innovation and related policy initiatives. In terms of supporting open innovation throughout Europe, the EU's focus is in four key areas - PUBLIC SECTOR: By providing a regulatory framework that supports and incentivizes open knowledge and cooperation; FINANCIAL SECTOR: By ensuring that innovation-friendly funding is available; INNOVATIVE BUSINESSES: By reducing market fragmentation throughout Europe to help companies commercialize their work; ACADEMIA: By supporting the development of co-creation capabilities and the ease with which research finds its way into business. Supporting 'Open Science' is a key part of the EU's desire for more effective and open innovation as it facilitates the free movement of knowledge throughout the continent. In this regard, EU is focusing efforts in five key policy areas - Fostering and creating incentives for open science; Removing barriers to open science; Mainstreaming and further promoting open access policies; Developing research infrastructures for open science; Embedding open science in society as a socio-economic driver. The final component of EU's open innovation strategy is to foster international cooperation in research and innovation. Horizon 2020, is one such program in the direction of making open science a norm globally. Moreover, international cooperation is key to tackle issues like climate change, driverless technology etc. The paper concludes, 'Science and innovation are global endeavours and researchers should be able to work together smoothly across borders, particularly on large-scale common challenges. The strategic approach to EU international cooperation aims to develop common principles and adequate framework conditions for engaging in cooperation.' Read on...

Team of researchers from IIT-Madras (India) and University of Nebraska at Lincoln (USA), are developing an ingestible capsule, that can stay in human body for close to a week, with sensors that will take readings of an individual's calorie intake, that can eventually help in diagnosis of diseases like cancer and permit sustained delivery of drugs. According to Prof. Benjamin Terry of UNL, 'The capsule, made of biocompatible materials, works like a parasite by latching on to the intestinal wall.' The sensors communicate their readings to an external device through low-intensity radio waves. Prof. P. V. Manivannan of IIT-M, says, 'The device is kept a metre away from the body. We use only low intensity waves that don't harm the body.' According to experts, biosensors could help monitor factors that influence digestive health. Prof. Terry adds that the mechanism could also serve as a long-term vessel for capsule endoscopes, the ingestible pill-shaped cameras that permit physicians to record images of the gastrointestinal tract.
