Tantalum(IV) iodide. Tantalum(IV) iodide is an inorganic compound with the chemical formula TaI4. It dissolves in water to give a green solution, but the color fades when left in the air and produces a white precipitate.

Preparation 

Tantalum(IV) iodide can be prepared by the reduction reaction of tantalum(V) iodide and tantalum. If pyridine is used as the reducing agent, there is an adduct TaI4(py)2.

Tantalum(IV) iodide can also be obtained by reacting tantalum(V) iodide with aluminum, magnesium or calcium at 380 °C. Ta6I14 is also formed. This makes it difficult to produce a very pure crystallized tantalum(IV) iodide.

Properties 

Tantalum(IV) iodide is a black solid. It has a crystal structure isotypic to that of niobium(IV) iodide. Single-crystalline tantalum(IV) iodide was first obtained in 2008 by Rafal Wiglusz and Gerd Meyer as a chance product of a reaction in a tantalum ampoule that was supposed to lead to the product Rb(Pr6C2)I12. The single crystal has a triclinic crystal structure with space group P1 (space group no. 2) with two formula units per unit cell (a = 707.36 pm, b = 1064.64 pm, c = 1074.99 pm, α = 100.440°, β = 89.824° and γ = 104.392°). The crystal structure differs from that of other transition metal tetraiodides, which usually have a MI4/2I2/1 chain structure, as it consists of TaI6 octahedra bridged over a common surface to form a dimer. Two such dimers bridge over a common edge to form a tetramer.

Technetium(III) iodide. Technetium(III) iodide is an inorganic compound with the chemical formula TcI3. It is the first iodide of technetium discovered and was first reported in 2013. Theoretical studies have shown that a single layer of TcI3 is ferromagnetic.

It can be obtained by the reaction of Tc2(CH3COO)4Cl2 and hydrogen iodide at 150 °C, or by the reaction of technetium and iodine at 300~400 °C. It decomposes in a vacuum at 450 °C to produce the metal technetium.

Edward Elwell Ltd. Edward Elwell Ltd was a company in Wednesbury (now in the county of West Midlands), England, that manufactured edge tools at Wednesbury Forge. The company was founded in 1817, and the forge closed in 2005.

History 
Edward Elwell (1783–1869), son of an ironfounder in Walsall, leased a forge in 1817 in Wood Green, Wednesbury, powered by water from the River Tame. There had been a water-powered forge in Wednesbury since at least 1597, when William Whorwood leased a forge owned by William Comberford. It may have been the same site as the forge at Wood Green, which by 1785 was one of four forges in the town.

Edward Elwell became known as a maker of quality edge tools, such as axes, hoes, shovels and spades. The machinery was powered by water and by steam engines. By 1851 Edward Elwell's son Edward (1814–1857) had taken over management of the company, but he resumed control on his son's death; his grandson Alfred took over when he died in 1869.

The company exported to many countries, including America, where it sold large quantities of edge tools during the American Civil War. The company was interested in the welfare of its workforce, converting former workshops into housing, and developing sports facilities. St Paul's Church, Wood Green, completed in 1874, was built by the Elwell family.

After Alfred Elwell's death in 1902 the business became a private limited company. The water wheels were replaced in 1904 by water turbines. In 1967, the company became one of the amalgamated firms of a newly formed company Spearwell Tools Ltd, and this was later taken over by Spear & Jackson. Wednesbury Forge closed in 2005, and the buildings were demolished in 2007.

Frederick Blakeslee. Frederick Blakeslee (December 4, 1898 – March 5, 1973) was an American illustrator.

Biography 
He was born in Buffalo, New York, to Bertha and Harland Manley Blakeslee, and had a younger sister, Helen, born in 1908.

When Blakeslee was 12 years old, Glenn Curtiss started a flying school in Buffalo, and in 1915 opened an aeroplane factory near Blakeslee's home.  Blakeslee worked for Curtiss as an assistant draughtsman in the design department, and was able to join test flights and learn more about the planes. He took night classes at Albright Art School in draughting and design skills, and also learned color theory and composition from teachers Lucius W. Hitchcock and Edward Dufner. Blakeslee's goal was to become an aviation designer, but he had to take introductory classes in drawing human figures.

He registered for the national draft on September 12, 1918, but the war ended soon afterwards and he was never inducted. Curtiss reorganized his business once the war was over, and Blakeslee became a designer for the Curtiss-Sperry Company. Being transferred to a Brooklyn factory in 1921, he then studied at the Pratt Institute of Brooklyn and then qualifying in 1926 as a professionally certified draftsman. While there he studied under Harold Winfield Scott, and made friends with several others who became well-known illustrators, including Walter M. Baumhofer and Rudolph Belarski. While a student at Pratt, he met and became engaged to Lorna Jones, a pupil in the librarian program and they married June 21, 1930. By 1927 he began taking on freelance art work, and then was commissioned to create the book jacket for Ernest Miltion's first novel, To Kiss the Crocodile.

By 1929 Blakeslee was painting pulp covers. His first was a cover for War Stories.   At around this time he got engaged to Lorna Jones, but she contracted tuberculosis and the wedding had to be delayed until after two years of treatment. They were married on Jun 21, 1930.

During the 1930s Blakeslee was creating covers for most of the pulp magazines that focused on aviation. His closest business relationship was with Henry Steeger, and from the mid 1930s most of Blakeslee's work was sold to Popular. From 1943, when Popular acquired Railroad Magazine, Blakeslee also began painting steam trains. In WWII, he served in the U.S. Coast Guard Reserve as a Seaman 1st Class on routine coastal patrols for Nazi U-Boats.

After the war, Blakeslee returned to his earlier occupation as a technical drawer of engineering specifications for the gyroscope division of Sperry-Rand Corporation at nearby Lake Success, New York, where he worked for 15 years, then retiring in 1963, where he and his wife moved to Danville, Vermont, where he painted landscapes of the White Mountains until his death of a heart attack on March 5, 1973. He was survived by Lorna, who died on March 29, 1978. They had no children.
