Potassium trichloridocuprate(II). Potassium trichloridocuprate(II) is a salt with chemical formula , more properly .

It is a member of the "halide" sub-family of perovskite materials with general formula  where  is a monovalent cation,  is a divalent cation, and  is a halide anion.

The compound occurs in nature as the bright red mineral sanguite.

The compound is also called potassium trichlorocuprate(II), potassium copper(II) trichloride, potassium cupric chloride and other similar names.  The latter is used also for potassium tetrachloridocuprate(II) .

Preparation and properties
The compound can be obtained by evaporation of a solution of potassium chloride  and copper(II) chloride  in 1:1 mole ratio.

The anhydrous form is garnet-red. It can be crystallized from a molten mixture of potassium chloride  and copper(II) chloride . or by evaporation from a solution of the salts in ethanol. It is very hygroscopic, and soluble in methanol and ethanol. It is antiferromagnetic below 30 K, and pleochroic, with maximum visible absorption when the electric vector is parallel to the Cu–Cu vector of the dimer.

Structure

Anhydrous

The anhydrous mineral form (sanguite) has the monoclinic crystal structure, with symmetry group P21/c and lattice parameters a = 402.81 pm, b = 1379.06 pm, c = 873.35 pm, and β = 97.137°,  cell volume V = 0.48138 nm3, and formulas per cell Z = 4.  The measured density is 2.86 g/cm3, close to the calculated one 2.88 g/cm3.  It contains discrete almost planar anions , each with the two copper atoms connected by two bridging chlorine atoms.  These anions are arranged in columns consisting of distorted edge-sharing  octahedra, stacked in double chains parallel to the a axis. The columns
occupy the edges and the centre of the cell's projection on the bc plane. The potassium atoms are located between these columns; each  cation is surrounded by nine chlorine atoms.  The mineral is optically biaxial (negative), with α = 1.653, β = 1.780, γ = 1.900', 2V= 85°. The mineral is named from the Latin sanguis (blood), alluding to its color.

Theoretical calculations for this topology give the lattice parameters as a = 1388.1 pm, b = 427.7 pm, c = 896.5 pm, α = 79.855°, cell volume V = 0.523891 nm3, calculated density 2.65 g/cm3.

Theoretical
An alternative theoretical structure for the compound has a cubic crystal system, symmetry group Pm3m[221], with the copper atoms arranged as corners of a cubic grid, a potassium atom at the center of each cube and a chlorine atom at the midpoint of each edge. The latice parameters are a = b = c = 485.8 pm, V = 0.114684 nm3, predicted density 3.03 g/cm3.

Friedrich Trautwein. Friedrich Trautwein ( August 11, 1888 in Würzburg – December 20, 1956 in Düsseldorf ) was a German engineer. Trautwein developed the Trautonium and is considered a pioneer of electronic music in Germany.

Life 
As a child, Friedrich Trautwein learned to play the organ in church. He studied electrical engineering at the Technical University of Karlsruhe, followed by law and physics in Berlin and Heidelberg. In 1906, he joined the Teutonia fraternity in Karlsruhe. 

He passed the traineeship examination for the higher postal service in 1911.  During WWI, he was a lieutenant in charge of a mounted radio squad.  After passing the assessor exam in 1919, he went on to study physics in Heidelberg and Karlsruhe, where he earned his doctorate in engineering.  He began working as a postal clerk at the Telegraphentechnisches Reichsamt the following year.  In this capacity, he was involved in the establishment of the first German radio station, which was based in Berlin's Vox building.  He was also dealing with electrical sound generation at the time, where he received his first patent for his research in 1922.

In 1929, he accepted a lectureship at Berlin's Academy of Arts and started the development of the Trautonium, which it would be finished in 1930. Trautwein was involved in the instrument's further development until around 1933, after which Oskar Sala continued to work on it independently. In 1933, he joined the NSDAP, which later became the SA. 

Trautwein started working at the Image and Sound Academy BIKLA in Düsseldorf in 1949, but it quickly closed down. Subsequently, Trautwein went to the Düsseldorf Conservatory (now the Robert Schumann Hochschule) with his students and established the foundation for a degree in audio and video technology that still exists today. Another musical instrument, the electronic Monochord, was developed in Cologne in 1952 as a further development of the Trautonium and allowed dynamic variations in the shape of the sound envelope.

Ruth Begun. Ruth Begun (née Weltmann) (3 April 1912 in Berlin, Germany - 11 November  2014 in Ohio, US). was the first woman to be awarded a physics PhD from the University of Berlin for her thesis on boundary layers of non-compressible fluids. She worked as rheologist and an Aerospace Engineer.

Scientific work 
She migrated to the United States in 1937 with her soon-to-be husband Semi Joseph Begun whom she married a year later. In the same year of her migrating, she started working at Interchemical corporation in New York City. In 1941 (or 1948) she moved to Ohio where she joined the NASA Glenn Research center as an Aerospace Engineer and co-developed the spacecraft ion engine before she was discharged of her duties in 1973. In 1976 she filed a lawsuit against NASA claiming she was unlawfully discharging her from her job claiming systemic sex discrimination.

Although women published before her, due to her well documented publications she is considered the 'first woman industrial rheologist'. During her work at Interchemical Corporation she met Henry Green, whom she worked with closely. In 1944, when Green developed an improved Couette-type rotational viscometer she developed and patented an accompanying recorder in 1945.  The flow curves recording mechanism allowed immediate interpretation and calculation of several values plastic viscosity, the yield value, and study the thixotropic behaviour. In her published work she proposed new analysis methods of rotational measurements and studied the properties of colloidal suspensions

Charitable work 
In 1972, the Beguns founded the Society for the Prevention of Violence (SVP) followed by 2001  the 'Begun Foundation' a supporting Foundation of the Jewish Federation of Cleveland, the foundation was dedicated to addressing the increased violence in society.

The Mandel School in Case Western University celebrated The Beguns social work in 2000 by establishing an endowed chair position to support a faculty member working in anti-violence research and education.

Other 
Begun wrote her first of book series 'Social Skills: Lessons and Activities for Pre-K' in 1990. Later she co-authored 'Ready-to-Use Violence Prevention Skills Lessons and Activities for Secondary Students' 1998 and 'Ready-to-Use Violence Prevention Skills Lessons and Activities for Elementary Students' in 1999 with Frank J. Huml.

HMS Falcon (1704). HMS Falcon was a 32-gun fifth rate built at Deptford Dockyard in 1703/04. Her initial assignment was with Sir Cloudesley Shovell's Fleet. She was then assigned to the Mediterranean where she was taken by the French in 1709.

Falcon was the thirteenth vessel to bear this name since it was used for a ballinger dating from 1343 and sold in 1352.

Construction and specifications
Falcon was ordered on 16 March 1703 to be built at Deptford Dockyard under the guidance of Master Shipwright Fisher Harding. She was launched on 2 December 1704. Her dimensions were a gundeck of  with a keel of  for tonnage calculation with a breadth of  and a depth of hold of . Her builder's measure tonnage was calculated as 411 tons (burthen).

The gun armament initially was four demi-culverins on the lower deck (LD) with two pair of guns per side. The upper deck (UD) battery would consist of between twenty and twenty-two 6-pounder guns with ten or eleven guns per side. The gun battery would be completed by four 4-pounder guns on the quarterdeck (QD) with two to three guns per side.

Commissioned service 1702-1709
Falcon was commissioned on 1 December 1704 under the command of Captain Charles Stewart then assigned to Sir Cloudesley Shovell's Fleet. Captain Bartholomew Candler was assigned as her commander on 27 January 1706. On 30 April 1706 Captain Robert Delvall assumed command for service in the Mediterranean. Captain Delvall dies on 29 January 1708. Captain William Massam took command on 17 May 1708 and held this command until his suicide on 2 October 1708. Captain Charles Constable took command after Captain Massam's death.In consort with Pembroke. they were detached to cruise between Toulon and Corsica.

Loss
Falcon was taken along with Pembroke by a French squadron off Toulon on 29 December 1709. She struck her colours when only 16 members of her crew were left unwounded.
