Water Forms ‘Spine of Hydration’ Around DNA

How water relates to and interacts with biological systems – like DNA, the building block of all living things – is of critical importance, and a Cornell University group has used a relatively new form of spectroscopy to observe a previously unknown characteristic of water.

Special X-Ray Technique Allows Scientists to See 3-D Deformations

3D_Bragg_900px.jpg

In a new study published last Friday in Science, researchers at Argonne used an X-ray scattering technique called Bragg coherent diffraction imaging to reconstruct in 3-D the size and shape of grain defects. These defects create imperfections in the lattice of atoms inside a grain that can give rise to interesting material properties and effects.

Atomic Structure of Irradiated Materials Is More Akin to Liquid Than Glass

Materials exposed to neutron radiation tend to experience significant damage. At the nanoscale, these incident neutrons collide with a material’s atoms, which then collide with each other. The resulting disordered atomic network resembles those seen in some glassy materials, which has led many in the field to use them in nuclear research. But the similarities between the materials may not be as useful as previously thought, according to this week’s The Journal of Chemical Physics.

Collecting Real-Time Data About Material Microstructural Evolution During Radiation Exposure

APL012721-Dennett-heterodyne_1.jpg

It may be surprising to learn that much remains unknown about radiation’s effects on materials. To find answers, Massachusetts Institute of Technology researchers are developing techniques to explore the microstructural evolution and degradation of materials exposed to radiation. They report a dynamic option, this week in Applied Physics Letters, to continuously monitor the properties of materials being exposed to radiation during the exposure. This provides real-time information about a material’s microstructural evolution.

Effect of Internal Curing as Mitigation to Minimize Alkali-Silica Reaction Damage

Report Sheds New Insights on the Spin Dynamics of a Material Candidate for Low-Power Devices

Magnetic_Insulator_Schematic_900x553.jpg

In a report published in Nano LettersArgonne researchers reveal new insights into the properties of a magnetic insulator that is a candidate for low-power device applications; their insights form early stepping-stones towards developing high-speed, low-power electronics that use electron spin rather than charge to carry information.
