Tetrachloroferrate. Tetrachloroferrate is the polyatomic ion having chemical formula . The metallate can be formed when ferric chloride () abstracts a chloride ion from various other chloride salts. The resulting tetrachloroferrate salts are typically soluble in non-polar solvents. The tetrachloroferrate anion, with iron(III) in the center, has tetrahedral geometry. It is useful as a non-coordinating anion comparable to perchlorate. Several organoammonium salts have been studied for their novel material properties. 1-Butyl-3-methylimidazolium tetrachloroferrate is one of several ionic liquids that are magnetic. Trimethylchloromethylammonium tetrachloroferrate is a plastic crystal that can behave as a molecular switch in response to several different types of inputs.

Niels Steenberg. Niels George Steenberg (31 November 1839 – 6 February 1915) was a Danish engineer who played an important role in the development of Denmark's chemical industry. He was professor of technical chemistry at the Technical University of Denmark from 1894 and president of the Danish Association of Engineers from 1907 to 1910.

Early life and education
Steenberg was born in Copenhagen, the son of military surgeon Frederik Steenberg (1802–1859) and Johanne Caroline Tengstedt (1811–1901). He attended Melchior's School before enrolling at the College of Advanced Technology in 1855 from where he graduated in applied sciences in 1861.

Career
Steenberg worked as factory manager for Jacob Holm & Sønner from 1865. He was responsible for the construction of the company's new glue factory in Sundbyøster as well as for modernizing its soap production. He was also responsible for the creation of a new laboratory which resulted in the introduction of new instruments and production methods. In 1890 he visited England to buy machinery for a new string factory at the company's ropewalk on Amager.

Steenberg succeeded August Thomsens as teacher of technical chemistry at the College of Advanced Rechnology in 1784 and he was the following year appointed as professor.

Steenberg was a board member of numerous companies, including A/S Hertz' Garveri og Skotøjsfabrik (1897–), A/S Københavns Fodtøjsfabrik (1906–), A/S H. E. Gosch & Co. (1902–), A/S Kbh.s Tændstikfabrikker, Fabrikken Merkur and A/S Det Danske Moler-Selskab (1909–).

He was a member of Industriforeningen's board of representatives from  1896 to 1908 and a board member of Den tekniske forening from 1898 until his death. He was president of the Danish Association of Engineers from 1907 to 1910.

Personal life
On 27 July 1869 in Mårum, Steenberg married Anna Dorothea Holten (1847–1884), daughter of forester Nicolai Holten (1815–1888) and Sophie Margrethe Ulrich (1820–1903). After her death, in Copenhagen on 20 May 1893 he married Anna Dorothea Cecilia Mogensen (1857–1916), daughter of iron foundry-owner Jens Frederik Frantz Mogensen (1823–1900) and Anna Dorothea Schou (1829–1917).

He died on 6 February 1915 and is buried in Copenhagen's Western Cemetery. He was created a Knight in the Order of the Dannebrog in 1903 and awarded the Cross of Honour in 1910. He is one of the men depicted in Peder Severin Krøyer's monumental group portrait painting Men of Industry.

ACFA-8. The ACFA-8 (Affordable Computers for All-8) was a microcomputer based on the Motorola 6808. It was released in 1979 by Andrew M. Veronis, a doctorate of computer science more well-known for his books on computer engineering.

Description and history
The ACFA-8 was a single-board microcomputer running the Motorola 6808. The board's memory layout comprised an array of eight chip sockets, onto which 3 KB or 6 KB DRAM chips can be populated, for a maximum of 48 KB of RAM. As stock it came with 16 KB of RAM. The computer's cassette interface supports the Kansas City standard, and the computer came shipped with 8-KB BASIC on cassette. The board features a built-in color RF modulator; American buyers got shipped a color video display for the price of the computer. Both American and overseas buyers however both got the board with an enclosure, a keyboard, and the power supply unit.

The ACFA-8 was one of the few microcomputers based on the 6808 microprocessor, being a lesser-cost component in the Motorola 6800 family. It was more popular with embedded processing systems in industrial environments. The computer came shipped with manuals describing the principles of operation, which Electronics Today International described as "really a computer course on their own". ACFA, Inc. (Affordable Computers for All), was founded by Andrew M. Veronis, a doctorate of computer science more well-known for his books on computer engineering. In the United States, the computer sold for $695 as an assembled kit or $595 unassembled. Computer journalist Fred Ruckdeschel felt that it needed an additional $300 in hardware on top of the cost of the unassembled kit to bring it on par with its contemporaries. To that end the ACFA-8 came with a RS-232C serial port for peripherals including teletypes.

ACFA, Inc. was incorporated at 130 Main Street in Annapolis, Maryland. This location was previously the home of Wicker Basket Ltd., a seller of wicker furniture, cookware, and fine china. Veronis bought that company in 1977 and was the proprietor of the store for a few years. Veronis forfeit ACFA shortly after its incorporation. He continued working in the computer industry in the following decades while also teaching computer science at the University of Maryland, College Park.

Butyl propionate. Butyl propionate is a butyl ester of propionic acid. This ester has the chemical formula .

Occurrence in nature
Butyl propionate is a plant metabolite, a human metabolite and an insect attractant. Butyl propionate is a natural ester found in Armenian apricot.

Preparation
Butyl propionate is derived by esterification of propionic acid with butanol.

Properties
Butyl propionate is a colorless liquid with a pear drops-like or apple-like odor. The liquid is less dense than water. Its vapor is 4.5 times denser than the air at the mean ocean level.

Uses
Butyl propionate is used to make fragrances, perfumes and as a flavoring. It is also used in paints and primers for auto body or engine, appliance coatings (paints designed specifically for painting household items and vehicles like microwave ovens, refrigerators and automobiles), enamels, lacquers, and printing inks, as a solvent for adhesives and nitrocellulose, and in polymerization reactions for acrylic resins.

Hazards and toxicity
Butyl propionate may irritate skin and eyes. Exposure to its vapor may cause eye and respiratory system irritation. Upon ingestion, causes abdominal pain and nausea. This chemical is very flammable. It may ignite even at ambient temperatures. Above , explosive mixtures with air may be formed. Strong oxidizing acids may cause a violent reaction that is sufficiently exothermic to ignite this chemical and the reaction products. Upon catching a fire, irritating, toxic and suffocating gases may be produced, such as carbon dioxide and carbon monoxide.

SibNIA TVS-2DTS. The SibNIA TVS-2DTS () is a utility aircraft developed by the Siberian Aeronautics Research Institute () under the program ljogki mnogozelevoi samoljot (Перспективный лёгкий многоцелевой самолёт) program for a light multi-role aircraft successor to the An-2 was developed. The abbreviation TVS stands for Turboprop Airplane (Turbovintowoy самолёт).

History 
The TVS-2DTS is a comprehensively modernized derivative of the twelve-seat An-2 biplane. The aircraft made its first flight on July 10, 2018, in Novosibirsk. It was planned to build five test aircraft to achieve certification in 2020.

In September 2019, it was announced that the SibNIA TVS-2DTS would not become the replacement of the An-2 aircraft type, rather the Ministry of Industry and Trade asked the government procurement portal for research and development for a design of a monoplane aircraft. The avoidance of non-Russian components and the engine played a significant role.

In October 2019 UZGA (Ural Works of Civil Aviation) won the tender from the Russian Ministry of Industry and Trade for the development of a replacement for the AN2 with the alternative UZGA LMS-901 Baikal aircraft.

Construction 
Unlike the aluminium biplane An-2, the TVS-2DTS is constructed of composites, has a turboprop engine and glass cockpit. It is based on the TVS-2MS, which has been in production since 2011. Unlike its predecessor, the fuselage and wings of the TVS-2DTS are made entirely of composite materials reinforced with carbon fibre. The lower wings have winglets that reach up to and are connected to the upper wings (closed wing). The STOL capabilities make the aircraft particularly suitable for military and civilian supply flights in areas with poor infrastructure. Other possible uses are firefighting or medical rescue flights.

Orders and deliveries 
In July 2017 there were 50 orders. The TVS-2DTS is to be built in the Novosibirsk region, initially at a production rate of 20 units per year.

Aberfeldy Footbridge. Aberfeldy Footbridge is a pedestrian bridge crossing the River Tay in Aberfeldy, Perth and Kinross. Built in 1992 and is the world’s first all-plastic bridge. Today the bridge still holds the Guinness World Record for the longest span plastic bridge, with an impressive 63m.

The bridge was initially used as a crossing for golfers at the Aberfeldy Golf Club to access the section of the course on the other side of the river, however when the Golf Course was downsized the bridge was no longer needed by golfers. The bridge is now used by walkers and cyclists to cross the river.

In 2016 the Golf Club decided the bridge needed work and put up barriers to stop people crossing. The bridge was later reopened after locals broke the barriers down, and although parts of the bridge are still held together with cable ties, the plastic bridge remains open.

BMW i Vision Dee. The BMW i Vision Dee is an electric concept car marketed by the German car manufacturer BMW. It is a model of the BMW i sub-brand. It is expected to reach production by 2025.

History
On 4 January 2023, BMW presented the i Vision Dee at the Consumer Electronics Show in Las Vegas.

According to BMW CEO Oliver Zipse, the car "demonstrates the possibilities that the combination of hardware and software opens up". This allows the driver to use the digital potential. According to the CEO, the design was inspired by an old chessboard from 1967. The central control is a mixed reality slider that transforms the windshield into a portal of digital experiences periodically. Shy-Tech technology touch sensors allow the vehicle owner to set digital content levels. In terms of dimensions, the model is close to the BMW 3 Series. To communicate with the driver, a voice assistant is built into the car. He expresses emotions not only with his voice, but also with lighting equipment. Instead of touch screens, there is a head-up display on the windshield. The car also changes color.

The i Vision Dee is planned to mass-produced in 2025.
