Structural adhesive offers high-temperature stability

DELO MONOPOX HT2860 achieves up to three times the strength at a temperature of 150 C compared to previous product generations. Ideal for bonding magnets in electric motors used in cars, drilling, milling tools, washing machines, as well as in many other applications, this new adhesive has a glass transition temperature (Tg) of 168 C. It achieves a strength of 18 MPa on sand-blasted aluminum at 150 C. This is up to three times higher than standard epoxy resins. The versatile epoxy resin can be heat-cured in an oven for 40 minutes at 150 C or by induction.

How specialized coatings can make mechanical parts harder for extreme industrial applications

Although bearings, gears, rollers, and other precision components are generally made of hardened steel or metal alloys, those used in high-load applications still can fail due to excessive wear, surface fatigue, pitting, galling, and corrosion. To address this problem, product engineers and component manufacturers often turn to specialized PVD (physical vapor deposition) coatings that can further harden the surface of these parts. Oerlikon Balzers provides solid solutions.

Stainless steel multiple-joint hinges

JW Winco now offers GN 7237 Stainless Steel Multiple-Joint Hinges with internal mounting brackets and a maximum opening angle of 180 deg. These multi-joint hinges are installed on the inside of flaps, hatches, or compartment doors to save space and ensure protection against vandalism. These hinges are generally used in pairs, meaning that one type L (left-hand) and one type R (right-hand) are used per opening. For higher loads, such as from large hatches, these can be supplemented with additional hinges of either type.

New carbon fiber material for SAAM additive systems from Cincinnati Inc.

Cincinnati Inc. (CI) has released a new carbon fiber resin material for its SAAM (Small Area Additive Manufacturing) fused filament fabrication 3D-printing system. The new material is impact resistant, lightweight, and has a very high strength-to-weight ratio. Carbon fiber reinforcement makes the material stiff, durable, and very low warping -- and advanced inter-layer adhesion results in accurate, quality parts with good dimensions. The material's superior surface finish makes it perfect for custom tooling applications, as well as assembly, CMM, welding, and CNC fixtures.

World's first particle foam based on polyethersulfone

After two years of intensive research, BASF is now able to present prototypes of the world's first particle foam based on polyethersulfone (PESU). The foam is characterized by its unique combination of properties: high-temperature resistance, inherent flame retardancy, and extreme light weight coupled with great stiffness and strength. It is therefore particularly well suited for complex-shaped components in cars, airplanes, and trains.

Conserve precious liquids with patented no-drip atomizing nozzles

EXAIR's new 1/8 NPT No Drip External Mix Atomizing Spray Nozzles mix liquid and air outside the nozzle and allow the air and liquid flows to be adjusted independently. The new, patented No Drip External Mix Atomizing Spray Nozzles work in the same way the company's standard atomizing nozzles do, but have the added benefit of positively stopping liquid flow when compressed air is shut off. Post-spray drips waste precious resources such as expensive coatings, chemicals, or water.

Spinning flare nuts eliminate loose fasteners in thin metal sheet applications

PEM SFN spinning flare nuts from Penn-Engineering become permanently captivated upon installation in thin metal sheets and, when paired with a self-clinching stud or other fixed externally threaded hardware, can eliminate all loose fasteners (including flange nuts) in attachment applications. These one-piece, flanged hex nuts additionally will spin freely in a sheet enabling quick attachment to mating hardware. Their use ultimately promotes savings in assembly time and costs.

From hydrogen fuel creation to aluminum joining and copper composites, Pacific Northwest National Lab lists 12 clean technologies almost ready for commercial use

PNNL's Solar Thermochemical Advanced Reactor System uses concentrated solar power to convert natural gas into more valuable fuels, including hydrogen for fuel cell cars. The system is among 12 PNNL-developed technologies that are receiving grants from DOE's Technology Commercialization Fund to move them closer to commercial use.

 

 

 

 

One dozen clean energy technologies that enable everything from lightweight, fuel-sipping cars to the expansion of renewable energy and cleaner fossil fuel use are getting a boost at the Department of Energy's Pacific Northwest National Laboratory (PNNL).

DOE is awarding PNNL about $4.4 million to bring the 12 technologies closer to commercial use, according to an announcement from DOE's Office of Technology Transitions about the first DOE-wide grants from its Technology Commercialization Fund. Companies partnering with PNNL to advance these technologies will also provide matching support, while PNNL will provide funding from its technology licensing income to support projects not involving industrial partners. PNNL is among 12 DOE national labs receiving a total of nearly $16 million to advance 54 different lab-developed technologies through the recent grant announcement.

The funds "will help to accelerate the commercialization of cutting-edge energy technologies developed in our national labs, making them more widely available to American consumers and businesses," said Lynn Orr, DOE's undersecretary for science and energy.

PNNL's 12 winning technologies, how they could be used, the lead PNNL researchers involved, and their partner organizations are as follows:

  1. Solar system that converts natural gas into hydrogen for fuel cell vehicles: Bob Wegeng and Richard Zheng, with STARS LLC, Southern California Gas Company, Infinia Technology Corp., Barr Engineering and Diver Solar LLC.
  2. Making fertilizer from coal fly ash, a byproduct of coal-fired power plants: James Amonette and Josef Matyas.
  3. Self-powered acoustic fish-tracking tag for evaluating fish passage at dams: Daniel Deng, with Advanced Telemetry Systems Inc., Idaho Power Company and Grant County Public Utilities District.
  4. Material manufacturing techniques to make more durable, longer-lasting components for dams: Kenneth Ross.
  5. Method to join aluminum parts made of different thicknesses and alloys for car manufacturing: Piyush Upadhyay, with Honda R&D Americas and Alcoa Inc.
  6. Highly conductive copper composite made with a new manufacturing process for use in high-powered electric motors: Glenn Grant, with General Motors.
  7. Computational prediction tools to improve power grid operations: Yuri Makarov and Pavel Etingov, with California Independent System Operator and AWS Truepower.
  8. Kilowatt-scale vanadium flow battery using an enhanced electrolyte for renewable energy storage: David Reed, with ITN Energy Systems.
  9. Electrolytes for rechargeable lithium batteries: Wu Xu, with Farasis Energy, Inc. and Navitas Systems.
  10. Seals for membranes used to convert natural gas to syngas: David Reed, with Praxair.
  11. Protective coating for solid oxide fuel cells: Jeff Stevenson, with Protonex.
  12. Seals for solid oxide fuel cells: Yeong-Shyung "Matt" Chou, with LG Fuel Cell Systems, Inc.

A full list of all of the winning Technology Commercialization Fund-supported projects is available on DOE's Office of Technology Transitions website.
