3. Some of the A*STAR innovations showcased also include:
A) TECHNOLOGIES FOR GREEN BUILDINGSNanoimprint Technology
B) TECHNOLOGIES FOR THE CONSTRUCTION INDUSTRY
Using sensors combined with signal processing and data mining techniques, this system will allow manufacturing plants to know its equipment’s health and energy consumption profile. This gives manufacturing operations visibility. By providing awareness of equipment availability and energy consumption profiles, companies can also then optimise their energy usage. This monitoring system can be applied in construction and prefab manufacturing plants, and steel mills encompassing varied equipment etc.
Details of all nine technologies on showcase are appended in the Annex.
4. These technologies benefits the industry in a timely fashion as Singapore moves towards achieving its target of greening at least 80% of its buildings by 2030.

A*STAR Technologies for Green Buildings and Construction Industry at BEX Asia 2010
1. Environmentally-friendly fire retardant and fire-proof additive
Many fire retardants, initially based on halogenated organic compounds classified as Persistent Organic Pollutants, are banned now in developed countries because of their environmental effects and other toxicity issues. These also require toxic heavy metal oxides as catalysts to function as fire retardants. Although phosphates and nitrogen containing compounds were developed to replace these halogenated organic compounds, these compounds also generate toxic gases upon exposure to flames and act as plasticisers enhancing the dripping hazard posed by plastics.
There is a demand for fire retardant which does not emit toxic gases and also do not act as a plasticiser.
One such example is the A*STAR-developed eco-friendly fire retardant and fire-proof additive which prevents the spread of fire by the intense formation of char at low temperatures, does not emit any toxic gases nor plasticise.
Since the char formation occurs around the temperature at which most of the organic compounds begin to generate volatile components, it effectively protects the flammable surfaces from burning. The char formation is through chemical reactions that are induced by the heat generated upon fire and does not require any external agents or catalysts. The fire retardant additive is used in coating formulations, foams, plastic, and fibres coating formulations. As a fire-proof additive, it is used in structural steel, shipping pallets, automotive applications like fire shield in various parts of the vehicle, aircraft, boats.For more information, please contact:
The concept of nanoimprinting resembles conventional hot embossing of the polymers – much like making a waffle! The strength of NIT lies in that once the mould has been made it can be used repeatedly to make simple, uniform patterns. The A*STAR team was one of the first to pioneer new methods to make complex, 3-D, nanostructures using a new method that was developed in Singapore - a technique called combinatorial-mould imprinting. The A*STAR team also has much experience in fabricating complicated 2D and 3D micro- and nanostructures on a variety of substrates for numerous applications.
Recently, A*STAR together with the Singapore Economic Development Board (EDB), International Enterprise(IE) Singapore and SPRING Singapore launched an Industrial Consortium On Nanoimprint (ICON). The goal is to open up NIT’s many benefits to industries to adopt this versatile technique into some of their existing processes. Partners in the ICON currently include A*STAR’s Institute of High Performance Computing, EDB, IE Singapore, SPRING, and Singapore’s DSO National Laboratories and Solves Innovative Technology Pte Ltd, Nypro, Inc. (US), Innox Co Ltd (Japan), NTT-Advanced Technology Corporation (Japan) and Youngchang Chemical Co., Ltd. (South Korea).For more information, please contact:
Multi-functional materials were printed on flexible and transparent plastic films using roll-to-roll processing. Printing of light emitting materials on plastic substrates enables ultra-thin, flexible and bendable films with surface area lighting. There is broad industry applications including ambient lighting, advertising, automotive, building, etc.For more information, please contact:
Under sunlight, the solar-driven self-cleaning coating has two functions, strong oxidation power and super-hydrophilicity. The strong oxidation power is able to oxidise away dirt and the super-hydrophilicity allows rain water to wash away dirt attached to the coated surface.
Self-cleaning coating can be applied on a wide variety of surfaces commonly found on buildings, such as painted building surfaces, walls, glass panels and windows. Buildings with self-cleaning abilities significantly reduce the need to wash, clean and maintain, thus saving maintenance costs, labour and time. The resultant reduction in the usage of cleaning agents, soaps or detergents will also save the environment from unnecessary water pollutants.For more information, please contact:
These methods may consume more energy, or use materials which are unfriendly to environment. An alternative technology has been developed.
A hand-held glass inspection device has been invented for inspecting glass panels mounted in high-rise building for NiS inclusion. The main feature of the inspection method is the illumination technique. Light is introduced into a glass panel and propagates along the glass by total internal reflection. An inclusion in the glass will cause the light to scatter. As such, inclusions and defects can be easily detected.For more information, please contact:
Thermal signatures emitting from a composite component housing a heated conductive network can allow the detection of sub-surface defects. Change in reflective index of embedded polymer optic-fibres can also be used to monitor the cure processes of fibre-reinforced composites. The sensors may be introduced into the composites via single-step, low pressure, low temperature processing techniques, with little additional processing costs. The application of polymer fibre optic sensors for cure monitoring in natural fibre composites is also a new area under development.
The other research partners are Delft University of Technology, Nanyang Technological University and the National University of Singapore.For more information, please contact:

Machine availability to produce parts reliably and without consuming excessive amount of energy is a challenge to manufacturers of pre-fabricated structures and steel components. Faulty machines and unplanned machine downtime creates havoc to the execution of job orders in manufacturing plants. Increasing energy prices forced manufacturers to reduce energy consumption without sacrificing on quality of parts produced. There is a need to develop technologies that can enable high visibility of equipment availability and increase manufacturing productivity.
The assimilation of sensing and data processing technologies combined will give plant owners and manufacturers a visibility of manufacturing operations. This will provide a full awareness on the equipment availability and energy consumption based on actual production throughout. Manufacturing operations can become more lean and energy efficient given reliable data collection and information extraction.
The technology can be used in most equipment for the construction and prefab manufacturing plants and steel mills. This will enable high manufacturing uptime and guaranteed production. Energy wastage can be significantly reduced without sacrificing on the quality of production and throughput. Product carbon footprint can be calculated in a realistic manner with increased accuracy.
Partners of the collaboration are Prof Jay Lee (University of Ohio Cincinnati) and Prof Frank Lewis (University of Texas Arlington)For more information, please contact:

The building blocks of matter in our universe were formed in the first 10 microseconds of its existence, according to the currently accepted scientific picture. After the Big Bang about 13.7 billion years ago, matter consisted mainly of quarks and gluons, two types of elementary particles whose interactions are governed by quantum chromodynamics (QCD), the theory of strong interaction. In the early universe, these particles moved (nearly) freely in a quark-gluon plasma.

Thin-film solar cells made of crystalline silicon are inexpensive and achieve efficiencies of a good 14 percent. However, they could do even better if their shiny surfaces reflected less light. A team led by Prof. Christiane Becker from the Helmholtz-Zentrum Berlin (HZB) has now patented a sophisticated new solution to this problem.
"It is not enough simply to bring more light into the cell," says Christiane Becker. Such surface structures can even ultimately reduce the efficiency by...
