1. The scanning probe microscope (SPM) can manipulate single atoms, move them in a controlled manner and help create novel nano-sized structures with very high precision. It can also map the terrain of living cells and allows biologists to obtain high-resolution images of a cell’s surface. The uniqueness and versatility of the tool is underscored in a new book by local researchers from A*STAR’s Institute of Materials Research and Engineering (IMRE). The book covers the practical uses of SPM and Singapore’s significant contribution in this area.
2. The SPM creates extremely accurate high-resolution images of a specimen’s surface by moving an extremely fine metal probe - which is a thousand times less than a hair’s breadth - across the surface, one parallel line at a time. SPM can be used to image materials with atomic-scale resolution and can be used to study living cells in their original liquid-filled environments. SPM has also allowed A*STAR IMRE scientists to create the world’s first controllable molecular gear and secure a place in a €10million European Union (EU) project to build a molecule-sized processor chip.
3. IMRE has more than 10 SPM systems which are used across multiple disciplines, such as physics, chemistry, and biology. Data gained from SPM can be used to benefit the semiconductor industry, advance molecular electronics, control friction between two surfaces at the molecular level and help in further scaling down the size of electronics.
4. “I believe it is a good showcase of Singapore’s concerted effort in translating science into technology”, said Dr Johnson Goh, a Senior Research Engineer with IMRE and one of the editors of the book. “This book covers the latest SPM research in Singapore, with many of the works looking beyond fundamental science to applications in nanoelectronics, biology and scalable nanolithography.” IMRE also conducts annual symposiums on SPM, which involve both academic and industry partners to further promote the industry-relevant advantages of the tool.
5. The book entitled, “Scanning Probe Microscopy”, will be published by World Scientific Publishing and will be internationally available after its launch on 15 December 2010 in conjunction with the 3rd Singapore Scanning Probe Microscopy Symposium (SingSPM 2010).Encl.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
