LNG spill. A liquefied natural gas (LNG) spill can happen during an accident or an intentional act. LNG is normally stored and transported in liquid form at a temperature of approximately . If this cooled liquid is released from a storage facility, pipeline, or LNG transport ship, then it begins to warm. As LNG warms above its storage temperature, the liquid begins to vaporize. The resulting gas produced by this warming is typically methane, which is the major component (with some ethane) of natural gas and one of the most potent and hazardous greenhouse gases. 

If a spill occurs and the vapor does not ignite, it would build to higher concentrations. At higher concentrations, the vaporized methane will cause an asphyxiation hazard to anyone exposed. If a spill or leak followed by a vaporization event were to occur in or near water, then water in contact with the spilled LNG can accelerate the vaporization process and increase the concentration of vapor in the immediate area. According to the 2004 Sandia report, this is of special concern to ship and pilot-boat crews, emergency response personnel or others who are exposed in a marine environment.

An ignition source close to the origin of the spill is likely to cause ignition and result in rapid burn off of natural gas vapors, rather than an explosion. No cargo explosions have ever been reported.

Comper Aircraft Company. The Comper Aircraft Company Ltd was a 1930s British light aircraft manufacturer. It was based at Hooton Aerodrome, Cheshire (1929–1933), and Heston Aerodrome, Middlesex (1933–1934).

History
In April 1929, after leaving the Royal Air Force, Nicholas Comper formed the Comper Aircraft Company Ltd, based at Hooton Park Aerodrome near Ellesmere Port in Cheshire. Company directors included his brother Adrian Comper, his colleague Flt Lt J. Bernard Allen, George H Dawson, the owner of Hooton Park Aerodrome, and others. The company's first product was the Comper Swift, a single-seat sporting monoplane. After the prototype flew in January 1930, 40 production examples were built at Hooton. In 1932, in a joint venture, the company produced a prototype of the Cierva C.25 autogyro, using major elements of a Comper Swift.

In March 1933, after producing about 41 aircraft, the company moved to Heston Aerodrome near London. The first aircraft built at Heston was the Mouse, that first flew in September 1933. Other single examples produced at Heston were the Comper Streak and Comper Kite.

After an expensive move in a financial depression, and new aircraft designs but few sales, the company ceased trading in August 1934. Most of the directors resigned, including Nick Comper, and a new board was formed, headed by Sir Norman J Watson and Brindley 'Bryn' R.S. Jones. The company was renamed Heston Aircraft Company Ltd, effective 10 August 1934.

Li Shouheng. Li Shouheng (; 1898–1995), also known as S. H. Li, was a Chinese educator, chemist and chemical engineer. Li founded the first chemical engineering department in China, thus is regarded as the Father of Modern Chinese Chemical Engineering. Li is also regarded as the first President of current Zhejiang University of Technology.

Biography

Li was born on 21 Feb 1898 in Yixing, Jiangsu, Qing Dynasty China. Li's courtesy name was Qiaonian ().

Aug 1920, Li went to study in United States. At beginning, Li studied at University of Michigan, Ann Arbor. Later he transferred to the University of Illinois at Urbana-Champaign. In 1923, Li obtained his MS, and PhD in May 1925 under S. W. Parr.

In July 1925, Li went back to China. In early April 1927, Li became a lecturer at Zhejiang Industrial School (one of early roots and technical schools of current comprehensive Zhejiang University). Li founded and led the Department of Chemical Engineering at Zhejiang University, which is the first chemical engineering department in China. The first BEng of Chemical Engineering students graduated from his department in 1928.

In May 1938, Li was designated the acting dean of the engineering faculty of Zhejiang University, by then university president Coching Chu. In Aug 1947, Li became the Provost of Zhejiang University. In 1950, Li became the head of Zhejiang University School of Engineering. In 1952, Li was repointed as the Provost of Zhejiang University, by the Ministry of Education of the People's Republic of China Centerial Government. From 1956 to 1958, Li was the Vice-president of Zhejiang University.

Later, the new Zhejiang Chemical Engineering School (the pre-existence of current Zhejiang University of Technology) was established, mainly based on the technical resources of Zhejiang University. Li was pointed as the president of the school, thus nowadays Li is also regarded as the first President of the Zhejiang University of Technology.

Li died on 18 Feb 1995 in Hangzhou.

Cobalt(II) hydroxide. Cobalt(II) hydroxide or cobaltous hydroxide is the inorganic compound with the formula , consisting of divalent cobalt cations  and hydroxide anions . The pure compound, often called the "beta form" (β-) is a pink solid insoluble in water.

The name is also applied to a related compound, often called "alpha" or "blue" form (α-), which incorporates other anions in its molecular structure.  This compound is blue and rather unstable.

Cobalt(II) hydroxide is most used as a drying agent for paints, varnishes, and inks, in the preparation of other cobalt compounds, as a catalyst and in the manufacture of battery electrodes.

Preparation
Cobalt(II) hydroxide precipitates as a solid when an alkali metal hydroxide is added to an aqueous solution of Co2+ salt.  For example,
Co2+  + 2 NaOH   →   Co(OH)2  +  2 Na+

The compound can be prepared by reacting cobalt(II) nitrate in water with a solution of triethylamine  as both the base and a complexing agent. It can also be prepared by elecrolysis of a solution of cobalt nitrate with a platinum cathode.

Reactions
Cobalt(II) hydroxide decomposes to cobalt(II) oxide at 168 °C under vacuum and is oxidized by air. The thermal decomposition product in air above 300 °C is Co3O4.

Like iron(II) hydroxide, cobalt(II) hydroxide is a basic hydroxide, and reacts with acids to form cobalt(II) salts.  It also reacts with strong bases to form solutions with dark blue cobaltate(II) anions, [Co(OH)4]2− and [Co(OH)6]4−.

Structure
The (β) form of cobalt(II) hydroxide has the brucite crystal structure, i.e. the arrangement of the atoms in the crystal are the same as the arrangement of the atoms in Mg(OH)2.  The Co(II) centers are bonded to six hydroxide ligands.  Each hydroxide ligand bridges to three Co(II) sites.  The O-H bonds are perpendicular to the planes defined by the oxygen atoms, projecting above and below these layers. Ignoring the H atoms, the packing of the anion and cations is also described as the cadmium iodide structure, in which the cobalt(II) cations have octahedral molecular geometry.

The beta form can be obtained as platelets with partial hexagonal geometry, 100-300 nm wide and 5-10 nm thick.

Alpha form
The so-called "alpha form" (α-Co(OH)2) is not a polymorph of the pure (β) form, but rather a more complex compound in which hydroxide-cobalt-hydroxide layers have a residual positive charge and alternate with layers of other anions such as nitrate, carbonate, chloride, etc. (the hydrotalcite structure).  It is usually obtained as a blue precipitate when a base like sodium hydroxide is added to a solution of a cobalt(II) salt.  The precipitate slowly converts to the beta form.

Nanotubes
Cobalt hydroxide can be obtained in the form of nanotubes, which may be of interest in nanotechnology and materials science.

Greenbird. Greenbird is a wind-powered vehicle that broke the land speed record for sail-powered vehicles at the dry Ivanpah Lake on March 26, 2009. It was built by the British engineer Richard Jenkins. Greenbird reached a peak speed of 126.1 mph (202.9 km/h).

Construction 
Greenbird, sponsored by Ecotricity, was described as being "a very high performance sailboat". It uses a rigid vertical wing, instead of the conventional sail, to generate thrust, in the same manner that the wing of an aeroplane generates lift. The only metal in the vehicle is in the wheels and the wing bearings; the remainder is made of carbon composite materials. The vehicle weighs about six hundred kilograms. According to Jenkins, the light weight and aerodynamic shape of the vehicle allows it to attain speeds three to five times faster than the speed of the wind. Greenbird is the fifth in a series of wind-powered land vehicles that Jenkins had constructed in his efforts to break the speed record. Jenkins said he had been trying to break the record for the past ten years in different locations, such as Australia, Britain, and the United States, but weather conditions were not suitable for him to reach maximum speeds.
