Team of researchers from Poland's Łódź University of Technology (ŁUT) led by Prof. Katarzyna Grabowska, the dean of the Faculty of Material Technologies and Textile Design, have developed a textile charger, which allows to charge phones, tablets, and other portable electronic devices using the power generated by their users' physical activity. Monika Malinowska-Olszowy, the vice dean of the faculty and member of the research team, says, 'The textile charger for mobile electronic devices is an inseparable part of the fabric or knitwear from which it is made, such as clothing...This invention replaces heavy, large batteries and power banks that often contain toxic substances. It is shock resistant and weatherproof. The main purpose of this technology is to ensure its users with uninterrupted access to electricity to sustain the operations of their mobile devices. As a result, this will exclude various problematic processes related to frequent charging of mobile phones or tablets.' ŁUT research has focused on the development of innovative textile inventions. Some of the latest examples include textile clothing for premature infants that is to protect them against dehydration and ensure thermal stability through special layered textile systems, and a prototype textronics solution that allows the integration of muscle-stimulating electrodes within various types of clothing, such as underwear, wristbands and socks, and use it to treat patients with various diseases that require such stimulation, among others.

Concrete is a preferred material, second-most used (about 22 billion ton annually), in the building and construction industry. But, it is also second-largest emitter of Carbon dioxide, as cement manufacturing accounts for 5-7% of annual emissions. According to Lucy Rodgers of BBC News, 'If the cement industry were a country, it would be the third-largest emitter in the world - behind China and the US.' In order to meet the requirements of the 2015 Paris Climate Agreement, annual cement emissions must fall by 16% by 2030. This situation brings concrete at the cusp of innovation, encouraging architects and scientists to experiment with concrete and help evolve its greener variants. Most innovations in this regard focus on reduction of cement in the concrete mix. MIT researchers developed an experimental method of manufacturing cement while eliminating CO2 emissions. Researchers at Lancaster University in the UK unveiled a novel approach of using nanoplatelets extracted from carrots and root vegetables to enhance concrete mixes. Dr. Sandra Manso-Blanco's approach of 'bioreceptive concrete' has structural concrete layered with materials to encourage the growth of CO2-absorbing moss and lichen. Another alternative mixture becoming mainstream in construction is GFRC (Glass Fiber Reinforced Concrete). The material consists of a mortar made of concrete, sand, alkali-resistant glass fiber and water. Plasticity is one of the main qualities of GFRC, enabling the molding of thinner and thus lighter façade pieces. Another novel approach to concrete used by Zaha Hadid Architects is 3D-knitted shell. Termed as KnitCandela, it is inspired by Spanish-Mexican architect and engineer Felix Candela's inventive concrete shell structures. The knitted fabric for KnitCandela was developed at ETH Zurich. ETH Zurich has been at the forefront of a number of innovations concerning concrete. With the intention of maximizing available space and avoiding steep construction costs, researchers from ETH Zurich's Department of Architecture have devised a concrete floor slab that with a thickness of a mere 2 cm, remains load-bearing and simultaneously sustainable. The institute also showcased the potential of robotically 3D printed concrete. Read on...

Researchers from IIT-Madras (Tamil Nadu, India), Prof. Asokan Thondiyath and research scholar Nagamanikandan Govindan, have designed and developed a multimodal robotic system, termed as 'Grasp Man', that has good grasping, manipulation and locomotion abilities. Their research, 'Design and Analysis of a Multimodal Grasper Having Shape Conformity and Within-Hand Manipulation With Adjustable Contact Forces', is recently published in ASME Journal of Mechanisms and Robotics. The robot is fitted with a pair of graspers that provide morphological adaptation, enabling it to conform to the geometry of the object being grasped, and allowing it to hold objects securely and manipulate them much like the human hand. The two graspers are equipped with a robotic platform that provides behavioural adaptation. The robot will have various industrial applications such as pipe inspection, search-and-rescue operations, and others that involve climbing, holding, and assembling. Prof. Asokan says, 'The motivation behind this research is to realise a robot with a minimalistic design that can overcome the need for task-specific robots that are capable of navigating and manipulating across different environments without increasing the system complexity.'

Research study, 'Onboard Evolution of Understandable Swarm Behaviors', published in Advanced Intelligent Systems by researchers from University of Bristol (Simon Jones, Sabine Hauert) and University of the West of England (Alan F. Winfield, Matthew Studley), brings development of a new generation of swarming robots which can independently learn and evolve new behaviours in the wild a step closer. Researchers used artificial evolution to enable the robots to automatically learn swarm behaviours which are understandable to humans. This could create new robotic possibilities for environmental monitoring, disaster recovery, infrastructure maintenance, logistics and agriculture. This new approach uses a custom-made swarm of robots with high-processing power embedded within the swarm. In most recent approaches, artificial evolution has typically been run on a computer which is external to the swarm, with the best strategy then copied to the robots. Prof. Jones says, 'Human-understandable controllers allow us to analyse and verify automatic designs, to ensure safety for deployment in real-world applications.' Researchers took advantage of the recent advances in high-performance mobile computing, to build a swarm of robots inspired by those in nature. Their 'Teraflop Swarm' has the ability to run the computationally intensive automatic design process entirely within the swarm, freeing it from the constraint of off-line resources. Prof. Hauert says, 'This is the first step towards robot swarms that automatically discover suitable swarm strategies in the wild. The next step will be to get these robot swarms out of the lab and demonstrate our proposed approach in real-world applications.' Prof. Winfield says, 'In many modern AI systems, especially those that employ Deep Learning, it is almost impossible to understand why the system made a particular decision...An important advantage of the system described in this paper is that it is transparent: its decision making process is understandable by humans.'

Team of researchers from University of Michigan at Ann Arbor (Prof. Timothy F. Scott, Prof. Mark A. Burns, Martin P. De Beer, Harry L. Van Der Laan, Megan A. Cole, Riley J. Whelan) have developed a new approach to 3D printing that lifts complex shapes from a vat of liquid at up to 100 times faster than conventional 3D printing processes. 3D printing could by highly beneficial for small manufacturing jobs without the need for a costly mold. But the usual 3D printing approach of building up plastic filaments layer by layer hasn't been usable in that aspect. Prof. Scott says, 'Using conventional approaches, that's not really attainable unless you have hundreds of machines.' The U. of Michigan innovative 3D printing method solidifies the liquid resin using two lights to control where the resin hardens - and where it stays fluid. This enables solidification of the resin in more sophisticated patterns. The process can make a 3D bas-relief in a single shot rather than in a series of 1D lines or 2D cross-sections. The printing demonstrations from this approach include a lattice, a toy boat and a block M. Prof. Burns says, 'It's one of the first true 3D printers ever made.' By creating a relatively large region where no solidification occurs, thicker resins - potentially with strengthening powder additives - can be used to produce more durable objects. The method also bests the structural integrity of filament 3D printing, as those objects have weak points at the interfaces between layers. Prof. Scott adds, 'You can get much tougher, much more wear-resistant materials.' The research paper, 'Rapid, continuous additive manufacturing by volumetric polymerization inhibition patterning', is to be published in Science Advances. Read on...

According to the report by Prof. Anne Boddington (PVC of Research, Business & Innovation at Kingston School of Art, Kingston University, UK), 'Future of design education in India', India needs to produce 65000 designs annually to satisfy the capacity of indigenous creative industry. The current production is around 5000 per year. Prof. Boddington is working on the development of arts and design education in India and collaborating with Indian Institute of Art and Design (IIAD). She says, 'Design and Art as a field is emerging in India. There is not only a huge opportunity but also a sense of enthusiasm and can-do attitude in Indians for it. But to match-up to the emerging field, there is a need to train teachers first...A design teacher needs to make the student autonomous and increase their level of creativity and understanding.' She recommends that arts and design education should not be limited to creative fields, but should also become part of all fields of learning. She considers critical listening, research, and quality assessment are part of design and art curriculum. According to her, there is a great potential to create interdisciplinary programs where creative skills will be imparted as a part of foundation courses. Read on...

The possibility of eco-friendly biodegradable paper-based batteries is now made a reality by the scientists at Binghampton University (SUNY), Prof. Seokheun 'Sean' Choi from the Electrical and Computer Engineering Department and Prof. Omowunmi Sadik from the Chemistry Department. Their research titled 'Green Biobatteries: Hybrid Paper-Polymer Microbial Fuel Cells' was recently published in Advanced Sustainable Systems. Prof. Choi engineered the design of the paper-based battery, while Prof. Sadik was able to make the battery a self-sustaining biobattery. The biobattery uses a hybrid of paper and engineered polymers. The polymers - poly (amic) acid and poly (pyromellitic dianhydride-p-phenylenediamine) - were the key to giving the batteries biodegrading properties. Prof. Choi says, 'There's been a dramatic increase in electronic waste and this may be an excellent way to start reducing that. Our hybrid paper battery exhibited a much higher power-to-cost ratio than all previously reported paper-based microbial batteries. The polymer-paper structures are lightweight, low-cost and flexible. Power enhancement can be potentially achieved by simply folding or stacking the hybrid, flexible paper-polymer devices.' Read on...

Apparel production is generally linked to environmental issues like water and air pollution, alongwith the land, water and pesticide use related to growing natural fibers. But now research points at the source of another problem created by apparels made wholly or partially from synthetic textiles. Microfibers, a type of microplastic, are shed during normal use and laundering, and remain in the environment similar to plastic packaging that coats so many of the world's beaches, and they bond to chemical pollutants in the environment, such as DDT and PCB. Moreover, the textiles from which they are shed are often treated with waterproofing agents, stain- or fire-resistant chemicals or synthetic dyes that could be harmful to organisms that ingest them. Also, microfibers are being consumed alongwith food and drink. Research review (Microplastics in air: Are we breathing it in? - Johnny Gasperi, Stephanie L. Wright, Rachid Dris, France Collard, Corinne Mandin, Mohamed Guerrouache, Valérie Langlois, Frank J.Kelly, Bruno Tassin) published last year shows that microfibers suspended in air are possibly settling in human lungs. Research led by Richard C. Thompson from the University of Plymouth (UK) in 2004 (Lost at Sea: Where Is All the Plastic? - Richard C. Thompson, Ylva Olsen, Richard P. Mitchell, Anthony Davis, Steven J. Rowland, Anthony W. G. John, Daniel McGonigle, Andrea E. Russell) documented and quantified the occurrence of microplastics in the marine environment. Research by Mark Anthony Browne, one of Prof. Thompson's graduate student, published in 2011 (Accumulation of Microplastic on Shorelines Woldwide: Sources and Sinks - Mark Anthony Browne, Phillip Crump, Stewart J. Niven, Emma Teuten, Andrew Tonkin, Tamara Galloway, Richard Thompson) found - (1) Samples taken near wastewater disposal sites had 250% more microplastic than those from reference sites and the types of microplastic fibers found in those samples were mainly polymers often used in synthetic apparel, suggesting the fibers were eluding filters in wastewater treatment plants and being released with treated effluent (which is released into rivers, lakes or ocean water). (2) A single polyester fleece jacket could shed as many as 1900 of these tiny fibers each time it was washed. Another 2016 study by researchers from UC Santa Barbara in US (Microfiber Masses Recovered from Conventional Machine Washing of New or Aged Garments - Niko L. Hartline, Nicholas J. Bruce, Stephanie N. Karba, Elizabeth O. Ruff, Shreya U. Sonar, Patricia A. Holden) has shown far higher numbers - 250000 fibers. Rosalia Project, a nonprofit focused on ocean protection, led a study of microfiber pollution across an entire watershed (from the mouth of Hudson River all the way to where the river meets the Atlantic in Manhattan). Rachael Z. Miller, group's director, was surprised to find that, outside of samples taken near treatment plants, there was no statistically significant difference in the concentration fibers from the alpine region to the agricultural center of New York state to the high population areas of Manhattan and New Jersey. This suggested to her that fibers might be entering surface waters from the air and from septic system drainfields in rural areas without municipal sewage systems. According to Textile World, demand for polyester has grown faster than demand for wool, cotton and other fibers for at least 20 years. And by 2030 synthetics are expected to account for 75% of global apparel fiber production, or 107 million tons. All textiles, including carpeting and upholstery, produce microfibers. So do commercial fishing nets. But due to the frequency with which apparel is laundered and the increasing quantities of clothing being purchased throughout the world (thanks at least in part to the so-called fast fashion trend), apparel is the microfiber source on which researchers and policy-makers are focusing attention. Krystle Moody, a textile industry consultant, says, 'Outdoor gear is heavily reliant on synthetic textiles due to their performance profile (moisture wicking) and durability.' Jeffrey Silberman, professor and chairperson of textile development and marketing with the Fashion Institute of Technology at the State University of New York, says, 'Price is the big driver behind the use of synthetics in textiles. A poly-cotton blend is generally far cheaper than a cotton one, but doesn’t look or feel appreciably different to most consumers. The motivation is to get natural-like fibers and still be able to get a price point that people are willing to pay.' Katy Stevens, sustainability project manager for the outdoor gear industry consortium European Outdoor Group (EOG), says, 'Initial research suggested that recycled polyester might shed more microfibers. Are we doing the right thing by using recycled polyester that might shed more? It has added a whole other big question mark.' Other studies have found microfibers in effluent from wastewater plants (Wastewater Treatment Works (WwTW) as a Source of Microplastics in the Aquatic Environment - Fionn Murphy, Ciaran Ewins, Frederic Carbonnier, Brian Quinn), in the digestive tracts of market fish (Ingested plastic transfers hazardous chemicals to fish and induces hepatic stress - Chelsea M. Rochman, Eunha Hoh, Tomofumi Kurobe, Swee J. Teh), throughout riversheds (Mountains to the sea: River study of plastic and non-plastic microfiber pollution in the northeast USA - Rachael Z. Miller, Andrew J. R. Watts, Brooke O. Winslow, Tamara S.Galloway, Abigail P. W. Barrows) and in air samples. Two separate studies released in March 2018 revealed that microfibers are found in bottled water sold all over the world. And a study published weeks later revealed that microplastic - chiefly microfibers - were present in 159 samples of tap water from around the word, a dozen brands of beer (made with Great Lakes water) as well as sea salt, also derived globally. Although most research has focused on synthetics textiles, but Abigail P. W. Barrows, an independent microplastics researcher who has conducted numerous studies on microfibers, says, 'Natural fibers such as cotton and wool, and semi-synthetics such as rayon should not be totally ignored. While they will degrade more quickly than, say, polyester, they may still be treated with chemicals of concern that can move up the food chain if the fibers are consumed before they degrade.' The study she led in 2018 (Marine environment microfiber contamination: Global patterns and the diversity of microparticle origins - Abigail P. W. Barrows, Sara E. Kathey, C. W. Petersen) found that in the surface water samples collected globally while 91% of the particles collected were microfibers, 12% of those were semi-synthetic and 31% were natural. Read on...
