Astronomers Make the Most Precise Measurement Yet of the Expanding Universe

April 8, 2014

0 Comments

Using 140,000 distant quasars, astronomers from the Sloan Digital Sky Survey have made the most precise measurement to date of the expanding Universe. The Baryon Oscillation Spectroscopic Survey (BOSS), the largest component of the third Sloan Digital Sky Survey (SDSS-III), pioneered the use of quasars to map density variations in intergalactic gas at high redshifts, […]

Scientists Use ‘Smart Window’ to Observe Lithium-Ion Battery Operation

April 3, 2014

0 Comments

By using ultrathin sheets of smart-window material, nickel oxide, as the anode in a lithium-ion battery, researchers were able to see for first time exactly what happens when the battery’s lithium ions make contact with the nickel-oxide layer and how the resulting reaction spreads out from several different points. High-tech “smart windows,” which darken to […]

Researchers Discover Natural 3D Counterpart to Graphene

January 17, 2014

0 Comments

A team of researchers has discovered that sodium bismuthate can exist as a form of quantum matter called a three-dimensional topological Dirac semi-metal (3DTDS), a natural three-dimensional counterpart to graphene with similar or even better electron mobility and velocity. The discovery of what is essentially a 3D version of graphene – the 2D sheets of […]

Berkeley Researchers Create First Soluble 2D Supramolecular Organic Frameworks

December 17, 2013

1 Comment

Berkeley Lab researchers have demonstrated the first soluble single-layer 2D honeycomb supramolecular organic framework that combines the ordering and porous features of metal-organic frameworks with the solubility of supramolecular polymers. Supramolecular chemistry, aka chemistry beyond the molecule, in which molecules and molecular complexes are held together by non-covalent bonds, is just beginning to come into […]

Researchers Use TEM to Record 3D Dynamic Imaging of Soft Materials

October 4, 2013

0 Comments

Through the use of transmission electron microscopy and a unique graphene liquid cell, Berkeley Lab researchers recorded the three-dimensional motion of DNA connected to gold nanocrystals. Autumn is usually not such a great time for big special effects movies as the summer blockbusters have faded and those for the holiday season have not yet opened. […]

Researchers Demonstrate High Temperature Superconductivity in a Topological Insulator

September 19, 2013

0 Comments

An international team of researchers has reported the first demonstration of high-temperature superconductivity in the surface of a topological insulator. Reliable quantum computing would make it possible to solve certain types of extremely complex technological problems millions of times faster than today’s most powerful supercomputers. Other types of problems that quantum computing could tackle would […]
