High-Entropy Alloy-Coated Nanolattice Structures

From Advanced Science News, October 9, 2017 by Sandra Kalveram:
 
"Periodic three-dimensional (3D) structures with nanoscale constituents, often referred to as ''nanolattices'', are of extensive interest recently due to the rapid advances in additive manufacturing (such as 3D printing) at the micro/nano-scale. High-entropy alloy (HEA) is a new kind of alloy constructed with equal or nearly equal quantities of five or more metals, showing unprecedented properties owing to their unique alloy design concept, tunable composition/microstructure, and adjustable mechanical properties as compared to conventional metal/alloys. By altering the design and material composition of these micro/nanolattices, it is possible to produce a wide variety of materials with unprecedented properties that defies traditional mechanics, such as strong yet ultra-lightweight structures. Researchers at the City University of Hong Kong microfabricated three-dimensional polymeric nanolattices which were conformably coated with a thin layer of high-entropy alloy (CoCrFeNiAl0.3) film via physical vapor deposition. The resulting structures demonstrate structural uniformity and desirable mechanical strength upon various characterizations. READ FULL ARTICLE.

 

New Optical Method Pinpoints Weak Spots in Jet Engine Thermal Coatings

From The Optical Society (OSA),  August 9, 2017:
 
" Researchers at Heriot-Watt University have demonstrated, for the first time, that an optical analysis method can reveal weak areas in ceramic thermal barrier coatings that protect jet engine turbines from high temperatures and wear. The technique could be used to predict how long coatings would last on an airplane and might eventually lead to new thermal barrier coatings, making engines more efficient and cutting both the cost and pollution of air travel.

Freeze-Dried Foam Soaks up Carbon Dioxide

From Rice University, August 16, 2017 by Mike Williams:

"Rice University materials scientists have created a light foam from two-dimensional sheets of hexagonal-boron nitride (h-BN) that absorbs carbon dioxide. They discovered freeze-drying h-BN turned it into a macro-scale foam that disintegrates in liquids. But adding a bit of polyvinyl alcohol (PVA) into the mix transformed it into a far more robust and useful material.The foam is highly porous and its properties can be tuned for use in air filters and as gas absorption materials. Blocks of hexagonal-boron nitride foam treated with polyvinyl alcohol proved able to adsorb more than three times its weight in carbon dioxide." READ FULL ARTICLE.
 

Superconductivity Found in Thin Films of Titanium Oxide


From EurekAlert!, October 2, 2017 by Tokyo Institute of Technology:
 
" Many of us are familiar with titanium dioxide (TiO2), a whitener commonly used in sunscreens and paints such as the white lines seen on tennis courts. Less well known are other higher titanium oxides -- those with a higher number of titanium and oxygen atoms than TiO -- that are now the subject of intensifying research due to their potential use in next-generation electronic devices. Researchers at Tokyo Institute of Technology have reported superconductivity in two kinds of higher titanium oxides prepared in the form of ultrathin films. They succeeded in growing thin films of Ti4O7 and γ-Ti3O5 for the first time using pulsed-laser deposition. Until now, the two materials had only been studied in bulk form, in which they behave as insulators. The formation of electrically conductive thin films is therefore seen as a big advance for fundamental physics. "   READ FULL ARTICLE.
  
 

IBM Sets New Storage Record for Roll-to-Roll Sputtered Magnetic Tape 

From  IBM, August 2, 2017:
 
" Research scientists have achieved a new world record in tape storage. The new record of 201 Gb/in2 (gigabits per square inch) in areal density was achieved on a prototype sputtered magnetic tape developed by Sony Storage Media Solutions. This new record areal recording density is more than 20 times the areal density used in current state of the art commercial tape drive, and it enables the potential to record up to about 330 terabytes (TB) of uncompressed data on a single tape cartridge that would fit in the palm of your hand. The results of the collaboration between IBM and Sony have led to various improvements in the media technology, such as advanced roll-to-roll technology for long sputtered tape fabrication and better lubricant technology, which stabilizes the functionality of the magnetic tape.

Atomic Layer Deposition (ALD) Coating of High-Precision Components Produced by Selective Laser Melting (SLM)


From Tech Briefs, August 1, 2017, by Marshall Space Flight Center, Alabama:

" The technology necessary to develop a state-of-the-art, low-cost method of polishing and coating a one-piece combustion device using electro-polishing (EP) and ALD was demonstrated in work by Summit Information Solutions, Inc., and Old Dominion University for the Marshall Space Flight Center. By combining material components made using Selective Laser Melting (SLM) with the process of EP and the application of uniform thin-film coatings using ALD, a complete, scalable manufacturing process can be developed by which high-precision, complex components can be produced at a fraction of their current cost. SLM technology has shown the potential to reduce production costs by 70% or more for complex propulsion component fabrication compared to traditional manufacturing techniques. " READ FULL ARTICLE.

2D Spectroscopy Simplified

From Photonics Spectra, September 2017 by Marco Arrigoni and Joseph Henrich (Coherent Inc.):

" Two-dimensional spectroscopy is now yielding findings on two material systems of particular interest to the photonics industry, namely molybdenum disulfide (MoS2) monolayers and perovskite films. At the University of California, Berkeley, Professor Graham Fleming's group's work has revealed that 2D spectroscopy is a powerful technique that delivers unique information that justifies its experimental complexity. While there are several different approaches to building a 2D spectrometer, they all require a femtosecond amplifier with at least one broadband optical parametric amplifier (OPA). The development of one-box integrated ultrafast amplifiers provides turnkey sources that eliminate virtually all the complexity formerly associated with generating femtosecond pulses for these experiments. This, in turn, is enabling scientists across numerous disciplines to use 2D spectroscopy to probe material systems for important applications in energy, light sources and other disciplines.

"Fizzy" Soda Water Could Be Key in Clean Manufacture of Graphene

From University of Illinois, August 17, 2017 by Mike Koon:

" As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. Graphene is synthesized by using chemical vapor deposition onto a metal substrate, typically copper foil. One particularly tricky aspect of producing graphene is how to separate this atomically thin material from its native metal substrate for integration into useful devices. The research group at the University of Illinois, has developed a cleaner and more environmentally friendly method to isolate graphene using carbon dioxide (CO2) in the form of carbonic acid as the electrolyte solution. The chemical vapor deposition synthesized graphene is easily transferred via under-etching delamination, allowing for multiple reuse of the metal catalyst substrate. READ FULL ARTICLE.
  
 

Beating The Heat with Nanoparticle Films

From Sandia National Laboratories, August 31, 2017:
 
" Supported by NMSBA grants and a Cooperative Research and Development Agreement, or CRADA, a team of researchers at Sandia National Laboratory spent several years trying to develop easy-to-apply polymer films with thermochromic nanoparticles.  Nelson Bell, a Sandia materials chemist, was primarily responsible for designing and implementing a multistage process to make nanoparticles. He also determined the best way to disperse the nanoparticles in a spray-paint-like mixture. By tweaking the "recipe" and adding tiny amounts of different metals, the team was able to make nanoparticles that could switch at any temperature from 200 degrees F to minus 40 degrees F. The first product they hope to get to market is a film to retrofit windows in late 2018. READ FULL ARTICLE.

A Novel and Practical Fab-Route for Superomniphonic Liquid-Free Surfaces


From Korea Advanced institute of Science and Technology (KAIST), September 8, 2017:
 
" A research team in the Department of Chemical and Biomolecular Engineering at KAIST has developed a fabrication technology that can inexpensively produce surfaces capable of repelling liquids, including water and oil. Mushroom-shaped surface textures, also called doubly re-entrant structures, are known to be the most effective surface structure that enhances resistance against liquid invasion, thereby exhibiting superior superomniphobic (repels all liquids) property. The existing procedures for their fabrication are highly delicate, time-consuming, and costly. Instead, the team used the photofluidization of azobenzene molecule-containing polymers to generate a superomniphobic surface which can be applied for developing stain-free fabrics, non-biofouling medical tubing, and corrosion-free surfaces. Azopolymer becomes fluidized under irradiation, and the fluidization takes place locally within the thin surface layer of the azopolymer. READ FULL ARTICLE.

Society of Vacuum Coaters Foundation

Founding Principle: The Society of Vacuum Coaters recognizes that in order to sustain its growth, it is important to attract young, well trained individuals to the field of Vacuum Coatings.

The SVC Foundation pursues this principle by providing scholarships to well qualified students planning to enter fields related to vacuum coatings, and/or providing stipends for travel expenses to attend the annual SVC Technical Conference, usually to present technical papers. The Society of Vacuum Coaters (SVC), the SVCF's founder, and AIMCAL, an organization committed to advancing vacuum roll-coating technology, and their members, provides support for the Foundation to pursue these goals.

Since its inception in 2002, the SVCF has awarded more than 50 scholarships and travel awards totaling over $180,000 to students from 18 countries. Our support can really have an impact in the life of these students; quoting a recent award recipient:

"Not only does the scholarship give the gift of financial support and the possibility to continue learning, it also gives those that have a passion for vacuum coating the blessing of attending such a wonderful program [SVC TechCon] to network and further their knowledge."

Inviting scholarship recipients to the SVC TechCon is an important element of the overall strategy for attracting new talent to our industry. Scholarship beneficiaries carry a special identification on the TechCon badge and we encourage you to meet them and make them feel welcome.

Scholarship Applications must be postmarked by November 30th of each year.
