Toxic-free Coating, On the Go

August 25, 2014 1:58 pm | Award Winners

The recent development of a new class of ionic liquid electrolytes has allowed the development of the Portable Aluminum Deposition System (PADS) by Oak Ridge National Laboratory and United Technologies Research Center. The breakthrough liquid formulation was achieved, in part, by the use of hydrophobic neutral ligands, which considerably increased the air stability of the plating electrolytes.

Automated Precision Weighing Handbook

August 25, 2014 1:56 pm | Product Releases | Comments

Weighing is one of the easiest and most accurate measuring methods for filling of syringes, vials, ampoules and tubes. Mettler Toledo has issued a new Automated Precision Weighing (APW) Handbook to educate end users and machine builders about selecting and applying weigh modules for automated weighing applications.

New class of materials discovered: Protein crystalline frameworks

August 25, 2014 1:45 pm | by New class of materials discovered: Protein crystalline frameworks | News | Comments

Protein crystals are extremely fragile, highly sensitive and hard to handle. Scientists in China have worked around these downsides by linking a protein crystal to helper molecules from the sugar family. When fixated, the molecules arrange themselves symmetrically within the helper molecule framework, forming crystals in which the proteins achieve high stability and are intricately interconnected into a protein crystalline framework.

Scientist uncover navigation system used by cancer, nerve cells

August 25, 2014 1:35 pm | News | Comments

Specialized cells can break through normal tissue boundaries and burrow into other tissues and organs. This crucial step in many normal developmental processes is guided by an extracellular cue called netrin, which orients the anchor cell so that it invades in the right direction. In a new study, researchers have shown how receptors on the invasive cells rove around the cell membrane ”hunting” for a missing netrin signal.

Razor-sharp TV pictures

August 25, 2014 1:24 pm | News | Comments

The future of movie, sports and concert broadcasting lies in 4K definition, which will bring cinema quality TV viewing into people’s homes. With its 3840 x 2160 resolution, 4K Ultra HD has four times as many pixels as today’s Full HD. The new HEVC video compression standard now allows broadcasters to transmit live video in the 4K digital cinema standard, and was used recently to broadcast a soccer game in Germany.

Physicists remove outcome unpredictability of three atoms binding at ultracold temperatures

August 25, 2014 1:20 pm | News | Comments

Findings from a physics study by a Kansas State Univ. researcher are helping scientists accurately predict the once unpredictable. They looked at theoretically predicting and understanding chemical reactions that involve three atoms at ultracold temperatures. Their findings help explain the likely outcome of a chemical reaction and shed new light on mysterious quantum states.

New technique for measuring nanostructures

August 25, 2014 1:17 pm | by Robert Emmerich, Julius-Maximilians-Universität | News | Comments

A team of scientists from Germany, Canada, and the United States has now developed a promising new measurement method that works without destroying anything yet offers nanoscale resolution. The method, an enhancement of resonant x-ray reflectometry identifies the chemical elements involved and is able to determine both the magnetic order and the electron distribution.

Automated Bin-picking

August 25, 2014 12:07 pm | Award Winners

Mitsubishi Electric Corp.’s MELFA-3D Vision system for industrial robot arms completely automates bin-picking tasks. A projector creates multiple slit patterns that are projected on the piled parts, which are captured with the camera. A depth map is reconstructed by using the captured images and a structured-light decoding algorithm.

Precision Stage for Nanoscale Studies

August 25, 2014 12:00 pm | Award Winners

A deeper understanding of microstructure-mechanical property correlations to processing conditions is sought by many industries. Hysitron Inc.’s xSol High Temperature Stage is a new platform that supports this effort, allowing researchers to make high-resolution nanomechanical measurements over a broad temperature range.

Lower Emissions, More Power

August 25, 2014 11:44 am | Award Winners

By 2025, the automotive industry is required to reduce carbon dioxide (CO2) emission by at least 30% while reducing pollutant emissions by a factor of three. For decades, efforts to meet ever-increasing standards like this have depended on a thorough understanding of Otto cycle dynamics in internal combustion engines and development of ways to change emissions through exhaust gas recirculation (EGR). Toward this goal, Dedicated-EGR (D-EGR) by Southwest Research Institute (SwRI) goes to new lengths by “dedicating” a separately controlled cylinder that is allowed to run rich.

Encoder-free Servo Motors

August 25, 2014 11:21 am | Award Winners

Industrial conveying and handling machines typically use expensive permanent magnet synchronous drives (“servo”) or cheaper induction motors equipped with brakes and clutches. Induction motors, because of their design, suffer from efficiency losses. Servo drives, meanwhile, are seen as less durable because they are equipped with sensitive encoders and extra wiring. Engineers at Mitsubishi Electric Corp. have eliminated the worst features of both designs with the Sensor-less Servo Drive Unit FR-E700EX Series and Sensor-less Motor MM-GKR, which controls speed or position without the need for an encoder.

Wide-area Millimeter Motions

August 25, 2014 11:04 am | Award Winners

Applications such as silicon wafer alignment or bio‐cell manipulations require fast and accurate positioning within a few millimeters working range. Widely used piezoelectric (PZT) actuators, however, have displacement ranges limited to hundreds of micrometers. Displacement-amplification techniques such as “inchworm” clamping have been introduced, but suffer from poor motion repeatability, low payload and low speed. This has produced a challenge for the precision engineering industry that has been met by the Singapore Institute of Manufacturing Technology (SIMTech) with the introduction of its Flexure‐based Electromagnetic Linear Actuator (FELA).

Super Superelastic Alloys

August 25, 2014 10:44 am | Award Winners

Corrosion, denting, abrasive wear and fatigue often lead to life-limiting bearing and gear failure in harsh conditions. Existing materials, such as hard steels, are prone to corrosion and rust; ceramics are non-conductive, difficult to manufacture and brittle; and superalloys are soft and susceptible to wear and damage. Working with Abbott Ball Company, NASA’s Glenn Research Center has successfully developed a set of methods to create high-performance alternatives to conventional bearing materials.

Stronger with Aluminum

August 25, 2014 10:24 am | Award Winners

Thermal fatigue is one of the most important properties in materials used as automobile’s exhaust parts, particularly near the hotter manifold section. When the exhaust gas passes through these parts, they thermally expand or shrink. But they can’t do this freely because of surrounding parts, which leads them to deform or fracture. The solution has long been to add molydenum to the ferritic heat-resistant stainless steels typically used for automobile exhausts. JFE Steel Corp., however, has achieved resistance to thermal fatigue fracture without the use of high-cost molydenum in its JFE-TF1 steel.

Fire Resistant Performance Wear

August 25, 2014 9:58 am | Award Winners

Roughly one million workers today are required to wear protective, fire-resistant (FR) garments in the U.S. However, because these protective garments are often heavy and uncomfortable, workers are reluctant to wear them and burn accidents are still commonplace. The iQ Series Comfort Knit Amplitude G2 Flame Resistant Fabric from Milliken & Company and Bulwark FR was designed to combine comfort with strong FR characteristics. It provides flash fire and arc flash protection while delivering three comfort attributes: lighter weight, breathability and moisture management.
