Finding out whether you have been infected with dengue may soon be as easy as spitting into a rapid test kit. A paper-based disposable device will allow dengue-specific antibodies to be detected easily from saliva within 20 minutes. Unlike blood samples, saliva can be collected easily and painlessly for rapid point-of-care diagnostics

The SPIE Photomask Technology Symposium, organized by SPIE and BACUS, the International Technical Group of SPIE, provides the world’s largest forum to discuss the latest mask technologies and how they can meet the needs of the rapidly moving semiconductor industry. It will be held Sept. 29-Oct. 1, 2015.
The EOS/ESD Annual Symposium will be held from Sept. 27-Oct. 2, 2015 in Reno, Nev. Founded in 1982, the ESD Association is a professional voluntary association dedicated to advancing the theory and practice of electrostatic discharge (ESD) avoidance.
SPIE Advanced Lithography is the premier conference for the lithography community. For 40 years, SPIE has brought together this community to address challenges presented in fabricating next-generation integrated circuits. It will be held February 22-26, 2015.
The semiconductor technology event SEMICON Korea will be held from Feb. 4-6, 2015.
Real-time testing of product packaging provides 100%, non-destructive monitoring. Ensuring package sealing integrity has long been an industry challenge, one in which the stakes are exceedingly high. Hanging in the balance are quality control standards that not only mandate pharmaceutical manufacturers’ adherence to strict guidelines and low tolerances, but also define their incalculably priceless reputations.
Controlling and monitoring particles is important for every type of cleanroom, be it semiconductor, pharmaceutical, food and beverage manufacturing, or biotech. While there is no perfect solution for detecting viable particles, understanding the options available can help determine the best solution for a specific cleanroom.
The Institute for Electronics and Nanotechnology is one of the founding NSF interdisciplinary academic research centers dedicated to nanotechnology discovery and development. The IEN evolved from its original focus as a NSF Microelectronics Research Center at Georgia Tech’s Atlanta campus. In 2009, the name was changed to the Nanotechnology Research Center.
Some of the most popular news stories on the Controlled Environments website in recent months have been about graphene, which has been dubbed as a “wonder material.” At one atom thick, this two-dimensional form of carbon is the thinnest material known — one million times thinner than a human hair. It is the world’s most conductive material and, at 200 times stronger than steel, it may very well be the strongest.
Researchers are covering soap bubbles with biomaterials that act as a disguise, tricking the body’s cells into mistaking the capsule for a bacterium, a cancer cell, or almost any other disease-causing cell. The flexible, cost effective technology is poised to change the way drugs and vaccines fight against bacteria, viruses, and cancer.
Photoelectrochemical water splitting, in which molecular hydrogen and oxygen are directly dissociated from water molecules using semiconductor electrodes, dates back to 1972. Certain factors have, however, delayed developments in this field over the last few decades. Photoelectrochemical water splitting using semiconductor electrodes with rough surfaces represents a promising route to the production of alternative fuels from sunlight.
Researchers have developed a comprehensive model to explain how electrons flow inside new types of solar cells made of tiny crystals. The model allows for a better understanding of such cells and may help to increase their efficiency. Compared with silicon in today’s solar cells, nanocrystals can be designed to absorb a larger fraction of the solar light spectrum. However, the development of nanocrystal-based solar cells is challenging.
A new signal amplification process developed by researchers is “now poised to fuel new generations of electrical and photonic devices – transforming communications, imaging, and computing.” The researchers have discovered a mechanism to amplify signals in optoelectronic systems that is far more efficient than the process long used by the semiconductor industry based on impact ionization.
The idea of computing systems based on controlling atomic spins just got a boost from new research. By constructing tiny "mirrors" to trap light around impurity atoms in diamond crystals, the researchers dramatically increased the efficiency with which photons transmit information about those atoms' electronic spin states, which can be used to store quantum information.
Swedish researchers have discovered that the insulation plastic used in high-voltage cables can withstand a 26 percent higher voltage if nanometer-sized carbon balls are added. This could result in enormous efficiency gains in the power grids of the future, which are needed to achieve a sustainable energy system.
New battery technology should be able to prevent the kind of fires that grounded Boeing 787 Dreamliners in 2013. The innovation is an advanced barrier between the electrodes in a lithium-ion battery. Made with nanofibers extracted from Kevlar, the tough material in bulletproof vests, the barrier stifles the growth of metal tendrils that can become unwanted pathways for electrical current.
