Speaking at the White House Summit on Nuclear Energy on November 6, physicist Christina Back of General Atomics (GA), San Diego, highlighted the urgency of developing next-generation fast-gas reactors with new materials to enhance safety and ensure energy security.
As GA's Director of Nuclear Technologies and Materials, Back specializes in developing new heat-resistant ceramics to enable delivery of cost-competitive clean energy with unprecedented safety via the innovative gas-cooled reactor, the Energy Multiplier Module or EM2.
She participated as one of five expert panelists at a forum spotlighting the Obama Administration's commitment to advanced nuclear energy and maintaining U.S. technology leadership in the industry. Back emphasized during her remarks that nuclear energy is the dominant energy source that is sustainable, compatible with 21st century power grids and free of greenhouse gases.
Panelists featured nuclear energy industry leaders including John Kotek, Acting Assistant Secretary for Nuclear Energy in the Department of Energy. The invited audience included leaders in academia, government, labor, environmental organizations, the nuclear industry, non-governmental organizations, think tanks and the investment community.
The panel focused on innovations in nuclear energy, with Back explaining that the design of EM2 draws on GA's 60 years of experience in designing and building safe reactors and aims to solve four big challenges: safety, waste, economics, and nonproliferation.
"Nuclear energy is important for the security of our country," says Back, noting that to turn new technology innovation into clean-energy reality, "We need investment and support from the DOE and Congress and the nation to understand what the challenges are, but also to understand what the huge payoff and benefits are for our country."
EM2 is a gas-cooled fast reactor designed to deliver low-cost nuclear energy by using a high-efficiency system, a "convert-and-burn" fuel cycle able to produce 265 megawatts-electric, in a compact modular design. It incorporates industry-leading safety and nonproliferation features and can run on nuclear waste.
The White House Summit on Nuclear Energy was billed by officials as a forum for highlighting the Administration's commitment to nuclear energy as a clean energy solution and "for maintaining U.S. leadership in nuclear energy to realize economic competitiveness, national security and nonproliferation objectives."
GA continues to be a leader in fission and fusion focused on a wide range of energy solutions. The DIII-D National Fusion Facility, operated by GA for the U.S. Department of Energy, is the largest magnetic fusion device in the nation and one of the largest in the world. GA is also a leading manufacturer of precision technology for inertial confinement fusion.

Ambrell launches Ekoheat with VPA for improved induction processes
Source:
Ambrell, Scottsville, N.Y., has launched a line of Ekoheat products featuring Versatile Performance Architecture (VPA), which enables a product to integrate into manufacturing systems, or to function as a stand-alone induction heating solution. The Autoscan capability includes easy-to-use functionality to scan a new application and auto-set the starting frequency, and then recommend RF setup parameters.
The products include soft-start circuitry, a safety feature that eliminates the risk of tripping up other equipment when a power supply is turned on. System power is tightly controlled on start-up to minimize transient spikes and electrical noise.
Ekoheat VPA includes a universal printed circuit board that can be used across the entire product line. This means fast availability of service repair and replacement parts, assuring business continuity and long-lasting product life. Regardless of system size and frequency, common PCBs are integrated into the designs. A single board-set addresses multiple systems, thereby minimizing inventory and eliminating model-specific versions.
These products are enabled for remote diagnostics and data collection with industrial Ethernet communication capabilities. In the industrial and automation environment, networking is fully supported using Ekoheat VPA's chosen gateway and includes CIPs (Common Industrial Protocols) such as EthernetIP, Modbus/TCP, and PROFINET protocols.

Lockheed Martin, Bethesda, Md., has closed its acquisition of Sikorsky Aircraft, a world leader in military and commercial rotary-wing aircraft. Aligned under the Lockheed Martin Mission Systems and Training (MST) business segment, Sikorsky Aircraft is now known as Sikorsky, a Lockheed Martin company.
"Today we are proud to welcome the Sikorsky team to Lockheed Martin," said Marillyn Hewson, Lockheed Martin chairman, president, and CEO. "Lockheed Martin and Sikorsky share a legacy of innovation and performance that has shaped the history of aviation for more than a century. Together, we are even better positioned to provide the best value for our customers, employees, and shareholders."
The acquisition advances Lockheed Martin's commitment to provide its customers with mission-ready solutions that are affordable and efficient, while expanding its core business into the growing areas of helicopter production and sustainment. Sikorsky's ability to leverage Lockheed Martin's scale will ensure that it remains a technology leader at the forefront of vertical lift.
Dan Schultz has been named president of Sikorsky, a Lockheed Martin Company. Mr. Schultz led the integration efforts for Lockheed Martin leading up to the closure, and he previously served as the vice president for Lockheed Martin's Ship & Aviation Systems line of business within MST.
"Dan is a former Marine helicopter pilot and has decades of experience in the rotary-wing segment, including leading Lockheed Martin's helicopter system integration business," Ms. Hewson said. "He brings a wealth of leadership experience and a deep understanding of our international customer base. I am confident he is the right person to lead Sikorsky at this pivotal time."
Sikorsky, a Lockheed Martin company, will retain its headquarters in Stratford, Connecticut. The line of business employs nearly 15,000 employees in 11 countries. Its helicopters are used by all five branches of the U.S. armed forces, along with military services and commercial operators in 40 nations.

Silver nanoparticles in polymer coating prevent infections in dental implants
November 8, 2015
Source:
Researchers at the Fraunhofer Institute, Germany, have reportedly developed DentaPlas, an antimicrobial coating for dental implants that consists of three layers, with two plasma polymer layers surrounding a center layer of silver nanoparticles. Within this structure, a biocide reservoir is formed, and the outermost layer releases the ions.
Scientists can tailor the silver concentration as well as the thickness of the layers and their porosity. This allows the silver ions to penetrate the outermost plasma polymer layer over a set period of time. When the silver reservoir is exhausted, no more silver ions are released, thus avoiding any long-term toxic effects.
In trials of finished implants and titanium test samples, the team demonstrated that the DentaPlas coating is not only anti-microbial, but also fully biocompatible and sterilizable. They confirmed the mechanical stability and robustness of the DentaPlas coating in trials using the lower jawbones of pigs taken from butcher shops. Here, they subjected the DentaPlas-coated implants to the rigors of being screwed into place with instruments in modern dental practice.
The DentaPlas coating passed this stress test with no problems. Project partner and Fraunhofer spinoff Bio Gate AG successfully transferred the processes of coating the test samples and titanium screws to its own production facilities. This medical technology company is also the manufacturer of the DentaPlas three-layer coating system.
A demonstration unit of the plasma polymer coating is currently available. Researchers will be presenting a dental implant featuring the DentaPlas coating at the MEDICA trade fair in Düsseldorf from November 16 -19 at the joint Fraunhofer booth (Hall 10, Booth G05).

Interactions Among Variables during Heat Treatment of Tool Steels
The diagram shows an overview of the main interactions during the heat treatment of steel alloys. Some of the main interactions take place between temperature, microstructure, and stress/strain. Especially for tool steels, these interactions are mainly influenced by the carbon content in the steel matrix, the types and relative amounts of the alloying elements, and the carbide formation/transformation/precipitation characteristics of the alloy system.
