Team of 25 researchers from 7 institutes in Europe, USA and China (Linköping University, Sweden: Shula Chen, Xiao-Ke Liu, Liangqi Ouyang, Yingzhi Jin, Galia Pozina, Irina A. Buyanova, Weimin M. Chen, Olle Inganäs, Fengling Zhang, Feng Gao; Georgia Institute of Technology, USA: Zilong Zheng, Veaceslav Coropceanu, Jean-Luc Brédas; Chinese Academy of Sciences, China: Deping Qian, Huifeng Yao, Sunsun Li, Bowei Gao, Jianhui Hou; École Polytechnique Fédérale de Lausanne, Switzerland: Wolfgang Tress; Imperial College, UK: Thomas R. Hopper, Artem A. Bakulin; The Hong Kong University of Science and Technology, Hong Kong: Jing Liu, Shangshang Chen, He Yan; University of Cambridge, UK: Jiangbin Zhang) have come together to develop rules for designing high-efficiency organic solar cells. Their research, 'Design rules for minimizing voltage losses in high-efficiency organic solar cells', was published in Nature Materials. Lead researcher, Prof. Feng Gao of Linköping University, says, 'We have formulated some rational design rules to minimize energy losses in organic solar cells. Following these rules, we present a range of examples with low energy losses and high power conversion efficiencies.' The research provides two fundamental rules to minimize energy losses in organic solar cells - (1) Minimize the energy offset between donor and acceptor components. (2) Make sure that the low-gap component in the blend has a high photoluminescence yield. According to researchers, theoretically the limit for the fraction of the sun's energy that can be obtained in solar cells is around 33%, but laboratory experiments with silicon-based solar cells have achieved 25% at best. Prof. Olle Inganäs of Linköping University, 'But we now know that there is no difference - the theoretical limit is the same for solar cells manufactured from silicon, perovskites, or polymers.'

Collaborative partnerships between local government, community, nonprofit organizations, academia and businesses can do wonders to enhance the various aspects of localities, cities and regions. An old factory site being rehabilitated as a business park in Lackawanna (New York, USA) is an example of sustainable redevelopment and the impact a local government can have on climate change. Erie County Executive Mark Poloncarz, Deputy Executive Maria Whyte and others officials visited Conrnell Universuty campus and discussed the redevelopment project with faculty and shared county initiatives focused on sustainability and economic growth, quality of life and building strong communities. Mr. Poloncarz says, 'Strong partnerships and sustainable practices are essential to progress, giving more people a say in their community and making responsible use of our resources to effect change that benefits generations yet to come.' Basil Safi, Executive Director of the Office of Engagement Initiatives at Cornell, says, 'The event was organized as a launching point to further community-engaged research and learning collaborations with Erie County', seeding ideas for potential projects involving Cornell students and faculty.' Initiatives for a Smart Economy (I4SE) is an economic development strategy Erie County enacted in 2013 and updated last year as I4SE 2.0. It contains 71 initiatives and is focused on inclusion and creating shared opportunities for all residents, to address persistent poverty and underemployment. Max Zhang, associate professor of mechanical and aerospace engineering at Cornell, says, 'I can envision that students team up with community partners to address specific challenges they are facing.' Rebecca Brenner, a lecturer at the Cornell Institute for Public Affairs, began a project in spring 2017 in Buffalo (NY) on improving communications during an emergency for that city's diverse, multilingual refugee population, and creating an emergency notification plan with nonprofit resettlement agencies as community partners. Erie County has about 300 current strategic initiatives led by county departments with community partners. They include fostering hiring of disadvantaged residents in high-poverty areas for construction jobs amid Buffalo's building boom; exploring the feasibility of a new convention center to spur tourism; creating an agribusiness park in rural southern Erie County; supporting health and human services agencies and energy programs targeting low-income households; and infrastructure and environmental remediation in county parks. Shorna Allred, associate professor of natural resources at Cornell, says, 'I was quite impressed and intrigued by what they are doing in Buffalo...We are similarly trying to bring together a partnership of people to work on sustainability issues across the city...'

Researchers at The University of British Columbia (Okanagan, Canada), Prof. Abbas Milani and graduate student Armin Rashidi, are working to solve the issue of wrinkling when it comes to making textile composites. Their research, 'A multi-step biaxial bias extension test for wrinkling/de-wrinkling characterization of woven fabrics: Towards optimum forming design guidelines', was recently published in Materials & Design Journal. According to Prof. Milani, wrinkling is one of the most common flaws in textile composites, which are widely used for prototypes, as well as mass production within prominent aerospace, energy, automotive and marine applications. Researchers have investigated several de-wrinkling methods and have discovered that they can improve their effectiveness by pulling the materials in two directions simultaneously during the manufacturing process. Mr. Rashidi says, 'The challenge was to avoid unwanted fibre misalignment or fibre rupture while capturing the out-of-plane wrinkles. Manufacturers who use these types of composites are looking for more information about their mechanical behaviour, especially under combined loading scenarios.' Prof. Milani, who is director of Materials and Manufacturing Research Institute at UBC Okanagan, says, 'Composite textiles are changing the way products are designed and built in advanced manufacturing sectors. As we continue to innovate in the area of composite textiles to include more polymer resin and fibre reinforcement options, this research will need to continue in order to provide the most up-to-date analysis for manufacturers in different application areas.'

Design as a separate field is getting more recognition in India. Policy initiatives like 'Design in India' and 'Make in India' will give design further impetus and assist in creating a thriving design ecosystem. India now have 30 to 35 design schools, most of them came up in the last few years. Prof. Anirudha Joshi of Industrial Design Centre at IIT-Bombay explores the condition of design education in India and suggests ways to make it better and more in tune with industry. He lists prevalent gaps between academia and industry - what is taught in design schools and what a professional designer need to do - (1) Uninentional gaps: Things that left out in design curriculums. Course duration is shorter than what is needed to become a good designer. (2) Lack of industry/hands-on environment: Certain things are best taught in industry setup and academic setup doesn't suit them. (3) Intentional gaps: Design school is not supposed to prepare students only for industry. Focus is on developing thought leaders having theoretical concepts and not just skills and training. (4) Limited availability of design teachers. (5) Lack of strong tradition in design research. (6) Lack of design education infrastructure. There is demand/supply gap in terms of skilled human resources. As the industry is growing, at least five million designers are required as compared to the current approximately 20000 designers. Many sectors like manufacturing, small scale industries, small printing and publishing houses etc, although have need for designers but can't afford one in the present scenario. Moreover, the focus of current designs is more global and there are few instances of designs that are specific to the Indian market. More emphasis should be given to designers that specifically focus on India. Read on...

According to the website tate.org.uk, 'Emotional architecture is a style of modernist architecture conceived in the 1950s that embraced space, colour and light, creating buildings that encouraged meditation and reflection. It was conceived by the Mexican architect Luis Barragán and the sculptor and painter Mathias Goéritz who were frustrated by the cold functionalism of modernism. In 1954 Barragán and Goéritz published 'The Emotional Architecture Manifesto' in which they argued that architecture needs to be spiritually uplifting.' Emotional architecture emphasises and respects human wants and needs. Researchers Ann Sussman (architect), Janice M. Ward (designer) and Justin B. Hollander (academic at Tufts University), are developing a scientific approach to this strategy, gleaning useful insights on how people look at structures and spaces. According to them the best way to understand what factors catch the eye is to literally study its movements through biometrics. Researchers used the same eye-tracking and facial-expression analysis software used by advertisers, software developers, and automotive designers to study our near-subconscious reactions to what we see. Ms. Sussman says, 'At the moment, biometrics are predominantly used to get people to purchase things. We'd like to use them to improve public welfare, health, and well-being. We want to promote better place-making in the world and ease of walkability.' Read on...

Richard J. Weller, professor of landscape architecture at University of Pennsylvania, and team of academics have created an online project called 'Atlas for the End of the World', a collection of maps and graphics to help viewers see where and how urbanization is in conflict with biodiversity. According to Prof. Weller, 'We mapped that interface between urban growth and the world's most valuable diversity...That conflict is bloody, it's disastrous, it's happening all over the world.' The project is an answer to Ortelius's 'Theatrum Orbis Terrarum' (Theatre of the World), printed in 1570 and thought to be the first modern atlas. Prof. Weller hopes that by 'mapping the intricacies of ecological conflict...architects, designers, and others can help create more ecologically sustainable relations between people and the planet.'

Norimasa Nishiyama of German Electron Synchrotron DESY, and international team of researchers from Germany and Japan (Ryo Ishikawa, Hiroaki Ohfuji, Hauke Marquardt, Alexander Kurnosov, Takashi Taniguchi, Byung-Nam Kim, Hidehiro Yoshida, Atsunobu Masuno, Jozef Bednarcik, Eleonora Kulik, Yuichi Ikuhara, Fumihiro Wakai, Tetsuo Irifune), have created a 2mm diameter disc of transparent silicon nitride, one of the hardest material known. The scientific report titled, 'Transparent Polycrystalline Cubic Silicon Nitride', was recently published in Nature. The transparent ceramic could be used for ultra-tough windows able to withstand extreme conditions. Windows that let users peer into engines and industrial reactors, or protect optical sensors from high pressures or heat are usually made of diamond, an expensive material that becomes unstable at 750°C. On the other hand, transparent silicon nitride ceramic can withstand temperatures upto 1400°C and is much cheaper. Read on...

Team of researchers from IIT-Kharagpur, Prof. Sudip Misra, Prof. N. S. Raghuwanshi, Anandarup Mukherjee and Arijit Roy, has designed India's first indgenous drone, BHIM, that can create a Wi-Fi zone within a nearly 1 km radius when it flies overhead. It is specifically designed for emergency and conflict situations. It has a battery backup of 7 hours, can fly into a disaster zone and create a seamless communication network for those involved in the operation. The automated drone has an actual vision-based guidance with built-in intelligence that helps it identify if an area is crowded or not. It will then fly away and land in a safer place. According to Prof. Sudip Mishra, 'Such advanced built-in intelligence is not available in drones now. The design is completely in-house. The controlling and guiding algorithms of the drone have been developed in our lab.' Internet of Things (IoT) is an important component of the drone. Read on...

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.
