Perfluoromethyldiethylamine. Perfluoromethyldiethylamine is a tertiary perfluorinated amine with the chemical formula C5F13N.  The compound consists of two pentafluoroethyl and one trifluoromethyl groups connected to nitrogen. The compound is produced for the electronics industry, along with other perfluoroalkylamines.  Unlike ordinary amines, perfluoroamines are nonbasic.

Preparation and use
Perfluoroalkylamines are prepared by electrofluorination of the parent amine using hydrogen fluoride as solvent and source of fluorine.
The compound has two commercial uses, although details are often proprietary.  It is a component in Fluosol, artificial blood.  This application exploits the high solubility of oxygen and carbon dioxide in the solvent, as well as the low viscosity and toxicity.  It is also a component of Fluorinert coolant liquids.  CPUs of some computers are immersed in this liquid to facilitate cooling.

Safety
Perfluoroalkyl amines are generally of very low toxicity, so much that they have been evaluated as synthetic blood.

Hex-Bus. The Texas Instruments Hex-Bus interface (sometimes used unhyphenated as Hex  Bus and with varying capitalization) was designed in 1982 and intended for commercial release in late 1983. It connects the console to peripherals via a high-speed serial link. Though it was prototypical to today's USB (plug and play, hot-swappable, etc.), it was never released, with only a small number of prototypes appearing in the hands of collectors after TI pulled out of the market. 

Several Hex-Bus peripherals were planned or produced. A WaferTape drive never made it past the prototype stage due to reliability issues with the tapes. The 5.25-inch floppy drive also never made it past the prototype stage, even though it worked. Prototype DSDD disk controllers and video controllers were also made. A 4-color printer-plotter, a 300-baud modem, RS-232 interface, an 80-column thermal/ink printer, and a 2.8" "Quick Disk" drive were the only peripherals released in quantity, mostly for use with the TI CC-40. All Hex-Bus peripherals could be used with a TI-99/4A when connected through the Hex-Bus Interface, through direct connection to the TI-99/8, or through direct connection to the Compact Computer 40.

Leith Corporation Tramways. Leith Corporation Tramways operated a passenger tramway service in Leith between 1904 and 1920.

History

On 23 October 1904, Leith Corporation Tramways took over operation of the Edinburgh Street Tramways routes within the corporation district. The electrification and modernisation was undertaken immediately, and the first electric service ran on 18 August 1905.

The fleet livery was munich lake and ivory.

Passengers going from Leith to Edinburgh had to change trams (from electric to cable-drawn) at Pilrig on Leith Walk at the boundary between Leith and Edinburgh. This confused exchange of passengers was known locally as "the Pilrig muddle", and lasted until the electrification of the Edinburgh Corporation Tramways system.

Takeover and closure

The services were taken over by Edinburgh Corporation Tramways on 10 November 1920 and continued to operate until 1956.

Materials genome. Materials genome is an analogy to genomes in biology, but in a conceptual sense: the many important phases, defects, and processes that make up engineered materials are the "genome" of materials science. The Materials Genome Initiative (MGI) is a federal, multi-agency effort to design, manufacture, and deploy materials and materials-based technologies significantly faster and cheaper than ever before. The MGI partially references the Human Genome Project, but only conceptually, and is a broader and less targeted effort.

History
The name "materials genome" was coined in December 2002 by Dr. Zi-Kui Liu who incorporated the company MaterialsGenome, Inc. in Pennsylvania, USA, and filed the trademark protection on March 5, 2004 (78512752). The Certificate of Registration (Reg. No. 4,224,035) was issued by the Patent and Trademark office on October 16, 2012.

In 2005, Zi-Kui Liu and Pierre Villars jointly crafted a proposal on "Materials Genome Foundation" when they met in Switzerland. In January 2006, they presented the proposal to a panel organized by ASM International.

In 2008, United States Automotive Materials Partnership (USAMP) supported by the United States Department of Energy funded a smaller version of the concept of "Materials Genome Foundation", which resulted in the development of the software package ESPEI.

In June 2011, the name "materials genome" was used in the United States National Science and Technology Council "Materials Genome Initiative"  in consent with MaterialsGenome, Inc.

In 2014, Liu published an article to reflect "Perspective on Materials Genome" in English, and in Chinese 

In early 2015, Chenxi Qian, Todd Siler and Geoffrey Ozin jointly published a paper in Small, discussing about the possibilities and limitations of a nanomaterials genome, expanding concept of the materials genome by incorporating the important parameters of nanomaterials such as size and shape information into the roadmap.

In May 2016, a group led by Sorelle A. Friedler, Joshua Schrier and Alexander J. Norquist claimed the first machine-learning-assisted materials discovery, as an example of humanity's early attempts to design and develop materials via data-driven approaches proposed by the Materials Genome Initiative.

In May 2017, progress on the Materials Genome Initiative was reviewed in 2017 at a workshop sponsored by NSF and future directions were identified.

Szekely Flying Dutchman. The Szekely Model V Flying Dutchman is a single seat sport aircraft that was built by the aircraft engine manufacturer Szekely in Holland, Michigan in 1928–29.

Development
The Flying Dutchman was designed in 1927 at the University of Detroit by professor Peter Altman. The aircraft was originally marketed by the Niles Aircraft Corporation as the Williams Gold Tip, powered by a three cylinder Anzani engine. The rights were purchased by Szekely to produce the aircraft using its own engine design. An airport was built in Holland to accommodate the company, opening on 28 August 1928, acquiring the name Szekely Airport in 1929. Szekely claimed a production capacity of 24 planes per week, though only 21 aircraft were produced in total. The Szekely company filed for bankruptcy in March 1932, and the factory assets were purchased by Michigan Bumper in 1936.

Design

The Flying Dutchman is a single place, low wing, open cockpit monoplane with conventional landing gear and a 3-cylinder Szekely engine. The fuselage was made of welded steel tubing with aircraft fabric covering.

Operational history
A Flying Dutchman was featured in the 1938 film Men with Wings.
