Do we live in a 2-D hologram?

August 26, 2014 1:16 pm | by Fermi National Accelerator Laboratory | News | Comments

A unique experiment at the Fermi National Accelerator Laboratory called the Holometer has started collecting data that will answer some mind-bending questions about our universe—including whether we live in a hologram. Much like characters on a television show would not know that their seemingly 3-D world exists only on a 2-D screen, we could be clueless that our 3-D space is just an illusion.

Vision problems for older adults can dim life expectancy

August 26, 2014 11:28 am | by Amy Patterson Neubert, Purdue Univ. | News | Comments

Older adults losing vision as they age are more likely to face an increased mortality risk, according to new research from Purdue Univ. The researchers analyzed data from the Salisbury Eye Evaluation study that tracked the vision health of 2,520 older adults, ages 65 to 84. The research was funded by the National Eye Institute.

Symphony of nanoplasmonic and optical resonators leads to laser-like light emission

August 26, 2014 11:20 am | by Rick Kubetz, Engineering Communications Office | News | Comments

By combining plasmonics and optical microresonators, researchers at the Univ. of Illinois at Urbana-Champaign have created a new optical amplifier (or laser) design, paving the way for power-on-a-chip applications. The speed of currently available semiconductor electronics is limited to about 10 GHz due to heat generation and interconnects delay time issues.

Nanofactory in a Box

August 26, 2014 11:06 am | Award Winners

Growing, harvesting and characterizing nanowires sounds like a job for an experienced researcher in a high-end laboratory. It often is. But EChem Nanowires Education Foundation Inc. has partnered with Argonne National Laboratory to bring nanowire fabrication to the classroom: The NanoFab Lab … in a Box! kit gives any student the ability to create nanowires and includes everything needed for the process, except the chemicals.

Resistance is Not Futile

August 26, 2014 10:52 am | Award Winners

In lithography, polymer “resists” are applied as a thin, continuous layer over material that is to be patterned. The resist is patterned, then removed after the pattern is duplicated on the silicon underneath. However, smaller patterns demand thinner resists, which can’t survive plasma patterning. Sequential Infiltration Synthesis (SIS) Lithography, developed by Argonne National Laboratory and implemented in industrial settings by several industry leaders, gives the resist the ability to withstand plasma etching.

Low-cost Solar through Fast Production

August 26, 2014 10:41 am | Award Winners

Crystalline silicon has continued to lead the market in the worldwide adoption of solar energy with over 85% market share. Much of this growth has happened in the past few years. Photovoltaic modules have dropped in price to below $1/W due to massive vertical integration largely driven by Chinese manufacturers. However, the cost to manufacture panels has not scaled down, resulting in losses for manufacturers. Crystal Solar Inc.’s Direct Gas to Wafer Epitaxial System, developed with the National Renewable Energy Laboratory, is designed to help reduce these costs by increasing throughput.

Fast Vacuum for Next-Gen Processes

August 26, 2014 10:20 am | Award Winners

The semiconductor industry is starting to adopt rapid processes that require pressure values processed in as little as 0.5 msec, yet produce low noise. This performance is needed to build chips that generate less heat, run cooler and need less cooling resources. Speed and noise improvements, available in INFICON’s new Stripe CDG capacitive diaphragm gauge, fulfill the requirements of this next level of structure reduction in the process industry.

Laser pulse turns glass into a metal

August 26, 2014 10:06 am | News | Comments

For tiny fractions of a second, when illuminated by a laser pulse, quartz glass can take on metallic properties. The phenomenon, recently revealed by large-scale computer simulations, frees electrons, allowing quartz to become opaque and conduct electricity. The effect could be used to build logical switches which are much faster than today’s microelectronics.

Accurate, Repeatable LED Metrology

August 26, 2014 9:58 am | Award Winners

The key step in the LED manufacturing process is the epitaxial growth of quantum well active layers on a wafer substrate using technology such as metal-organic chemical vapor deposition (MOCVD). The characterization of the resulting “epi” wafer is typically done by the “indium dot” method, a slow and largely manual method that involves injecting current into dot electrodes that test the wafer, but also damages it. Bruker Nano Surfaces has an alternative.

Visual Observation of Materials in Supercritical Fluids

August 26, 2014 9:02 am | Product Releases | Comments

Supercritical Fluid Technologies’ SFT Phase Monitor II is a tool for determining the solubility of various compounds and mixtures in supercritical and high-pressure fluids. It provides direct, visual observation of materials under conditions precisely controlled by the researcher.

Fraction Collection Storage Solution

August 26, 2014 8:58 am | Product Releases | Comments

Porvair Sciences has introduced a complete storage solution for HPLC fractions comprising its 2-mL round deep well microplate and high-integrity cap mat seals. The design of the 2-mL deep well plate, which provides scientists with a 2-mL working volume in a 45-mm height plate, is now coupled with a choice of specially designed cap mats.

Materials scientists, mathematicians benefit from newly crafted polymers

August 26, 2014 8:55 am | News | Comments

Polymers come with a range of properties dictated by their chemical composition and geometrical arrangement. Yasuyuki Tezuka and his team at Tokyo Institute of Technology have now applied an approach to synthesize a new type of multicyclic polymer geometry. While mathematicians are interested because these structures have not been realized before, the geometry studies also provide insights for chemists.

C2D2 fighting corrosion

August 26, 2014 8:48 am | by Anna Maltsev, ETH Zurich | News | Comments

Bridges become an infrastructure problem as they get older, as de-icing salt and carbon dioxide gradually destroy the reinforced concrete. A new robot called C2D2 (Climbing Corrosion Detecting Device) is now in use in Switzerland and can check the condition of these structures, even in places that people cannot reach.

New project is the ACME of addressing climate change

August 26, 2014 8:40 am | News | Comments

Eight U.S. Dept. of Energy national laboratories are combining forces to use high performance computing to build the most complete climate and Earth system model yet devised. The project, called Accelerated Climate Modeling for Energy, or ACME, is designed to accelerate the development and application of fully coupled, state-of-the-science Earth system models for scientific and energy applications.
