Carbon paste electrode. A carbon-paste electrode (CPE) is made from a mixture of conducting graphite powder and a pasting liquid. These electrodes are simple to make and offer an easily renewable surface for electron exchange.  Carbon paste electrodes belong to a special group of heterogeneous carbon electrodes. These electrodes are widely used mainly for voltammetric measurements; however, carbon paste-based sensors are also applicable in coulometry (both amperometry and potentiometry).

Advantages
In general, CPEs are popular because carbon pastes are easily obtainable at minimal costs and are especially suitable for preparing an electrode material modified with admixtures of other compounds thus giving the electrode certain pre-determined properties. Electrodes made in this way are highly selective sensors for both inorganic and organic electrochemistry.
Carbon paste, glassy carbon paste, glassy carbon etc. electrodes when modified are termed chemically modified electrodes. Chemically modified electrodes have been employed for the analysis of inorganic and organic species.

Disadvantages
The biggest disadvantage of CPEs, which limits their applicability in practical analysis, is that success in working with carbon paste-based electrodes depends on the experience of the user. While this is true for any type of solid electrodes, CPEs are rather an exceptional case. In contrast to commercially available solid electrodes for which basic electrochemical characteristics are comparable for almost all products from each manufacturer, each carbon paste unit is an individual, where the physical, chemical and electrochemical properties may differ from one preparation to another. For this reason each probe must be calibrated individually. While this may not be an issue in a research environment, it would be a considerable burden in production service.

Applied Digital Data Systems. Applied Digital Data Systems, Inc. (ADDS), was a supplier of video display computer terminals, founded in 1969 by Leeam Lowin and William J. Catacosinos. Lowin simultaneously founded Solid State Data Sciences (SSDS). SSDS was one of the first developers of the MOS/LSI integrated circuits that were key to ADDS's product line.

It became a subsidiary of NCR Corporation in 1980, which sold the Mentor 2000 professional computer in the United States in 1986.

The Mentor 2000 ran at 5 MHz using a Zilog processor, 640 KB RAM, and included one 60MB hard disk. It used the Pick operating system and database management system. It was able to manage 16 or 32 video terminals at once.

ADDS (along with NCR) was later part of AT&T,
then independent briefly before being acquired by SunRiver Data Systems.

However, their version of the Pick operating system was acquired by Pick Systems Inc, now called TigerLogic.  That version is now called mvBase.  MvBase was sold to Rocket Software in 2013.

RSS-DEV Working Group. The RSS-DEV Working Group was the outgrowth of a fork in RSS format development. The private, non-commercial working group began with a dozen members in three countries, and was chaired by Rael Dornfest, researcher and developer of the Meerkat RSS-reader software.

History
RSS-0.90 was released by Netscape circa March 1999, at which point the acronym implied RDF Site Summary. The functionality was remarkably different from what is now known as RSS, or Really Simple Syndication. The former simply provided a website summary, while the latter was designed for syndication. July 1999 saw the release of RSS-0.91, an improvement on its predecessor; the latter was XML-based, as opposed to the use of RDF (or Resource Description Framework) by the earlier version, which was then deprecated by Netscape. The new version also provided support for DTD, allowing for additional HTML-like functionality.

Development fork
The following year, UserLand Software released its own RSS-0.91, circa June 2000. Unlike the Netscape version, this variant had no support for DTD. A team of developers, which would become members of the core development team of the RSS-DEV Working Group, broke away from the project. This group released its own set of specifications called RSS-1.0, on December 6, 2000.

RSS-1.0 marked a return to the use of the Netscape-deprecated RSS-0.90; the group also created its own interpretation of the RSS acronym — RDF Site Summary. This version, which was developed in parallel to the UserLand version, was incompatible with all other versions.

Short Sarafand. The Short S.14 Sarafand was a British biplane flying boat built by Short Brothers. It was planned as a general reconnaissance aircraft for military service. When it was built in 1932 it was the largest aeroplane in the United Kingdom.

The Sarafand was first proposed by Oswald Short in 1928 as an enlarged development of the Singapore II, to provide transatlantic range capability. Short managed to persuade first his chief designer Arthur Gouge and then the Chief of the Air Staff, Sir Hugh Trenchard (later Viscount Trenchard) of the feasibility of such a large aircraft and Air Ministry specification R.6/28 was drawn up to define the project. It was conducted as a public/private joint venture, the Air Ministry funding it with £60,000 and Short Brothers providing the rest. The aircraft was originally designated the Short R6/28 before being named the Sarafand.

Design
The Sarafand was a six-engined biplane flying boat with equal span wings. Due to the high wing end loads, Gouge specified corrugated steel spars for both upper and lower wings. The six engines, in tractor/pusher pairs, were housed in monocoque nacelles mounted between the wings on integral girders; the central nacelle was further supported by two pairs of splayed struts to the lower wing-roots. The hull, largely constructed of anodised Alclad, had a stainless-steel planing bottom. It had a monoplane tail unit with one large fin and two small auxiliary fins on the tailplane.

Operational history
The Sarafand prototype was built at No. 3 Shop at Rochester, but the shop did not have enough height to fit the upper wing. The semi-completed flying boat was launched into the river on 15 Jun 1932 and moved to a new slipway, originally called the Barge Yard, for final assembly. The maiden flight, with Shorts' chief test pilot John Lankester Parker at the controls and Oswald Short as co-pilot, was made at Rochester on the River Medway on 30 June 1932. Only one S.14 was built (serial S1589); it was later used for experimental flying at the Marine Aircraft Experimental Establishment at Felixstowe. The Sarafand was scrapped there in 1936.

Zinc nitride. Zinc nitride (Zn3N2) is an inorganic compound of zinc and nitrogen, usually obtained as (blue)grey crystals. It is a semiconductor. In pure form, it has the anti-bixbyite structure.

Chemical properties
Zinc nitride can be obtained by thermally decomposing zincamide (zinc diamine) in an anaerobic environment, at temperatures in excess of 200 °C. The by-product of the reaction is ammonia.
3 Zn(NH2)2 → Zn3N2 + 4 NH3

It can also be formed by heating zinc to 600 °C in a current of ammonia; the by-product is hydrogen gas.
3 Zn + 2 NH3 → Zn3N2 + 3 H2 The decomposition of Zinc Nitride into the elements at the same temperature is a competing reaction. At 700 °C Zinc Nitride decomposes. It has also been made by producing an electric discharge between zinc electrodes in a nitrogen atmosphere. Thin films have been produced by chemical vapour deposition of Bis(bis(trimethylsilyl)amido]zinc with ammonia gas onto silica or ZnO coated alumina at 275 to 410 °C.

The crystal structure is anti-isomorphous with Manganese(III) oxide. (bixbyite).  The heat of formation is c.  per mol. It is a semiconductor with a reported bandgap of c. 3.2eV, however, a thin zinc nitride film prepared by electrolysis of molten salt mixture containing Li3N with a zinc electrode showed a band-gap of 1.01 eV.

Zinc nitride reacts violently with water to form ammonia and zinc oxide.
Zn3N2 + 3 H2O → 3 ZnO + 2 NH3

Zinc nitride reacts with lithium (produced in an electrochemical cell) by insertion. The initial reaction is the irreversible conversion into LiZn in a matrix of beta-Li3N. These products then can be converted reversibly and electrochemically into LiZnN and metallic Zn.

Yttrium(III) chloride. Yttrium(III) chloride is an inorganic compound of yttrium and chloride. It exists in two forms, the hydrate (YCl3(H2O)6) and an anhydrous form (YCl3).  Both are colourless salts that are highly soluble in water and deliquescent.

Structure
Solid YCl3 adopts a cubic structure with close-packed chloride ions and yttrium ions filling one third of the octahedral holes and the resulting YCl6 octahedra sharing three edges with adjacent octahedra, giving it a layered structure. This structure is shared by a range of compounds, notably AlCl3.

Preparation and reactions
YCl3 is often prepared by the "ammonium chloride route," starting from either Y2O3 or hydrated chloride or oxychloride. or YCl3·6H2O. These methods produce (NH4)2[YCl5]:

10 NH4Cl  +  Y2O3  →  2 (NH4)2[YCl5]  +  6 NH3 + 3 H2O

YCl3·6H2O + 2 NH4Cl → (NH4)2[YCl5] + 6 H2O

The pentachloride decomposes thermally according to the following equation:
 (NH4)2[YCl5]   →   2 NH4Cl  +  YCl3
The thermolysis reaction proceeds via the intermediacy of (NH4)[Y2Cl7].

Treating Y2O3 with aqueous HCl produces the hydrated chloride (YCl3·6H2O). When heated, this salt yields yttrium oxychloride rather than reverting to the anhydrous form.

Chichester Bell. Chichester Alexander Bell (1848 – 11 March 1924) was an Irish audio engineer and inventor. He was a cousin of Alexander Graham Bell and was instrumental in developing the graphophone.

Life 

Bell was born in Dublin, Ireland, in 1848 to Professor David Charles Bell (1817–1903) and Ellen Adine Highland. David Charles was an elder brother to Professor Alexander Melville Bell, the renowned British authority on elocution and speech.

Bell received his Baccalaurei in Medicinâ degree in Medicine and Surgery from Trinity College Dublin on 30 June 1869. Prior to moving to Washington, D.C. to join his cousin Alexander Graham Bell's Volta Laboratory, Chichester was assistant professor of chemistry, University College London. In 1881 Chichester Bell began working with Alexander and their associate Charles Tainter on addressing the drawbacks to Thomas Edison's phonograph.

The three men created the Volta Laboratory Association to be the holder of their patents. Their successful development of the graphophone led to the formation of the Volta Graphophone Company of Alexandria, Virginia in February 1886 by the principals, along with Chichester's brother, lawyer and banker, Charles B. Bell (born 1858). While living in Washington, D.C., Chichester Bell was one of the founding members of the Chemical Society Washington Chapter.

He then returned to University College, London to continue his scientific research. In 1887, he published "Sympathetic Vibration of Jets" in the Philosophical Transactions of the Royal Society. Chichester Bell also helped establish the Edison Bell company. The Edison Bell company was established on 30 November 1892 in London to sell phonographs produced by the Edison United Phonograph Company.

Bell was awarded the John Scott Medal of the Franklin Institute in 1900. He married Antoinette Ives in 1889, in Montreal, Quebec, Canada and died at Radcliffe Infirmary, St Giles, Oxford, Oxfordshire, England, on 11 March 1924.

Vanadium(III) fluoride. Vanadium(III) fluoride is the chemical compound with the formula VF3. This yellow-green, refractory solid is obtained in a two-step procedure from V2O3.
Similar to other transition-metal fluorides (such as MnF2), it exhibits magnetic ordering at low temperatures (e.g. V2F6.4H2O orders below 12 K).

Preparation
The first step entails conversion to the hexafluorovanadate(III) salt using ammonium bifluoride:
V2O3 + 6 (NH4)HF2 → 2 (NH4)3VF6 + 3 H2O

In the second step, the hexafluorovanadate is thermally decomposed.
(NH4)3VF6 → 3 NH3 + 3 HF + VF3

The thermal decomposition of ammonium salts is a relatively common method for the preparation of inorganic solids.

VF3 can also be prepared by treatment of V2O3 with HF.
VF3 is a crystalline solid with 6 coordinate vanadium atoms with bridging fluorine atoms. The magnetic moment indicates the presence of two unpaired electrons.
