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.

Atomic structure of ultrasound material not what anyone expected

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.
In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...
A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.
By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
