Robert Fan. Robert Fan Wenzhao (1893-1979) was an important figure among first-generation twentieth century Chinese architects, specifically for Shanghai’s architectural modernist movement in the 1930s.

Biography 
Born in Shanghai, Fan got a degree in engineering from St John's University in 1917. After working at St John's as engineering professor for two years, Fan pursued a Bachelor's degree in architecture from the University of Pennsylvania, graduating in 1922. There, he studied under Paul Philippe Cret, who had been trained in the Beaux-Arts style. Fan travelled extensively in Europe and America, acquiring a taste for modern, Western architectural styles, such as Art Deco.

Upon his return to Shanghai in 1922, Fan joined the Sino-American engineering venture Lam, Glines & Company (允元公司) of Von-Fong Lam  (1891–1987). Three years later he opened one of the first Chinese architectural practices in Shanghai with fellow University of Pennsylvania alumnus Zhao Chen. Fan and Zhao designed the Nanking Theater in 1930 (now called the Shanghai Concert Hall), near People’s Square, before parting ways to start separate firms.

The following year, Fan also designed the Chinese YMCA (now the Marvel Hotel Shanghai), combining typical elements of Chinese architecture with Modern lines. He is also responsible for the Art Deco Majestic Theatre on Jiangning Lu in Jingan, built in 1941. Beyond his own firm, Fan worked with the government on several occasions. He served as a member of the Committee of the Nanjing City Planning Bureau in 1929, and was a technical consultant for the Ministry of Railways in Nanjing in 1932; where he was responsible for both the Railway and Health Ministries.

Eventually, Fan abandoned his Beaux-Arts training to embrace Modernist thinking. In 1933, he completed the Yafa Court apartment complex (253 – 267 Wuyuan Road). These apartments were advertised as having “modern sanitation, central heating, hot and cold water, Westinghouse refrigerators, and garages”. Fan also designed, in 1942, the Georgia Apartments on Hengshan Road in a late Art Deco style.

His also worked in Hong Kong on several buildings of the Chinese University's Chung Chi College (1956), Shek Kip Mei Police Station (1960), North Point Methodist Church (1961), Silver Capitol Cinema in Kwun Tong (1964), Hoover Theatre in Causeway Bay, Hong Kong Spinners Factory in Cheung Sha Wan and the Vitasoy Bottling Plant in Kwun Tong.

After the Communists took control of China in 1949, Fan fled with his wife to Hong Kong, at the age of 56.

Sphinx (home automation system). The Sphinx () was an experimental Soviet project for a home automation system, commissioned by the State Committee for Science and Technology and designed by Dmitry Azrikan, in collaboration with A. Kolotushkin and V. Goessen, in 1987. Sphinx, an acronym for Super Functional Integrated Communication System (), was intended to be an ensemble of modules that would allow consumers to easily interact with information systems.

The home environment, as described in a 1987 issue of Soviet magazine Technical Aesthetics (), would be composed of "spherical speakers, a detachable monitor, headphones, a handheld remote control with a removable display, a diskette drive, a processor with three memory blocks and more". The modules were designed to be used collectively, or individually by family members, and the number of memory blocks was supposed to be possibly increased endlessly according to the needs of the household so different family members could activate different programs simultaneously.

According to Sergey Moiseyev, Head the VNIITE (Russian design research institute):

The configuration of the Sphinx station, with detachable monitors and speakers, prefigured the environment of computer stations with peripheral touch pads and accessories that characterises informatics systems in the beginnings of the 21st century.

Pentachlorobenzenethiol. Pentachlorobenzenethiol is a chemical compound from the group of thiols and organochlorine compounds. The chemical formula is .

Synthesis
Pentachlorobenzenethiol can be obtained from hexachlorobenzene.

Properties
Pentachlorobenzenethiol is a combustible gray solid with an unpleasant odor, practically insoluble in water. It has a monoclinic crystal structure. The compound is not well-biodegradable and presumably bioaccumulable and toxic for aquatic organisms. 
Pentachlorobenzenethiol is itself a metabolite of hexachlorobenzene and is found in the urine and the excretions of animals receiving hexachlorobenzene. Pentachlorobenzenethiol has a high potential for long-range transport via air as it is very slowly degraded in atmosphere.

Applications
Pentachlorobenzenethiol is used in the rubber industry. The compound is added to rubber (both natural and synthetic) to facilitate processing (mastication).

1,2-Dibromoethylene. 1,2-Dibromoethylene, also known as 1,2-dibromoethene and acetylene dibromide, is a dihalogenated unsaturated compound with one bromine on each of the two carbon atoms. There are two isomers of this compound, cis and trans. Both isomers are colorless liquids.

Synthesis
1,2-Dibromoethylene can be synthesized by halogenation of acetylene (CH) with bromine (Br). In order to prevent the formation of tetrahalogenated compounds, acetylene is used in excess, with Br as the limiting reagent.

Alternately, halogenation of this kind could also be achieved through the use of two equivalents of N-bromosuccinimide and lithium bromide (LiBr). N-Bromosuccinimide provides Br as an electrophile, which is followed by Br from LiBr.

Hexadecanethiol. 1-Hexadecanethiol is a chemical compound from the group of thiols. Its chemical formula is .

Synthesis
1-Hexadecanethiol can be obtained by reacting 1-bromohexadecane with thiourea.

Properties
1-Hexadecanethiol is a combustible colorless liquid with an unpleasant odor, which is practically insoluble in water.

Applications
1-Hexadecanethiol is used as a synthesis chemical. The compound is also used for the production of nanoparticles and hydrophobic self-assembling monolayers. The high affinity of the thiol group to the elements of the copper group causes the thiols to spontaneously deposit in a high-order layer when a corresponding metal of a 1-hexadecanethiol solution is exposed.

Toxicology and safety
The substance decomposes upon combustion with the formation of toxic gases, including sulfur oxides. It reacts violently with strong oxidizing agents, acids, reducing agents, and metals.

ARL Tracteur C. The "ARL Tracteur C", or ARL Char C, was a French super-heavy tank design. It was developed during the late Interbellum, by the Atelier de Construction de Rueil (ARL) company. A full-scale wooden mock-up was part produced, but the project was terminated in favor of FCM F1 (a directly competing design, which proved to be superior). The vehicle was meant to be extremely heavy and for that time period, very heavily armored. ARL C was intended to be very long to meet the requirement to cross trenches up to 7 meters wide. The tank was multi-turreted like FCM F1; however, unlike FCM F1, ARL C had the main turret in front of the very long hull right behind the secondary turret, not in the back of vehicle. The development path of the ARL C was extremely complex, due to the existence of a number of parallel super-heavy tank projects with overlapping design goals, the specifications of which were regularly changed. For each project in turn several companies submitted one or more competing proposals.

Second World War 

In September 1938, the ARL company was granted a development contract for the char maximum, the first proposal for which was presented by ARL in May 1939. It had a proposed weight of 120 tons, consisted of two detachable modules, armor up to 120 mm thick and could be armed with either a gun or a flamethrower. The commission decided that only the guntank would be considered, however.

In 1940, the specifications of ARL's tank, now named as "Tracteur C" to keep the project secrecy for outsiders, were changed: the tank was designed to have two turrets, 47 mm gun on front and on new larger turret, a 90 mm gun. ARL on 17 January 1940 ordered four turrets from the Schneider company, but it agreed only to build two 105 mm gun turrets and refused the two 90 mm gun turrets, as there was simply no capacity to manufacture them. In April 1940, after AMX's AMX Tracteur C programme was terminated, the subcommission advised to go ahead with both the FCM F1 and the ARL prototypes and immediately place an order for ten or fifteen of the former. That advice was given to a new overarching Commission of Tank Study, to which ARL presented a wooden mock-up on 11 April 1940; FCM presented one the next day. It transpired that the FCM project was far more advanced and could show the new tank in every detail. Due to this, the ARL's project was terminated. Only partially finished full-scale wooden mockup was produced.

After Fall of France, in July 1940, the wooden mockup was captured by German forces. However, as the French super-heavy designs were absolutely unnecessary for the Wehrmacht, the mockup was soon dismantled and design documentation was apparently destroyed.
