It is a multi-luminescent dark green crystalline solid with a vapor pressure between 1-3 mmHg at 373.15 K.  is stable in a vacuum, dry air, nitrogen and helium at room temperature. It is soluble in carbon tetrachloride (). Compared to the other uranium halides, little is known about .

Structure and Bonding

Uranium hexachloride has an octahedral geometry, with point group Oh. Its lattice (dimensions: 10.95 ± 0.02 Å x 6.03 ± 0.01 Å) is hexagonal in shape with three molecules per cell; the average theoretical U-Cl bond is 2.472 Å long (the experimental U-Cl length found by X-ray diffraction is 2.42 Å), and the distance between two adjacent chlorine atoms is 3.65 Å.

Chemical properties
Uranium hexachloride is a highly hygroscopic compound and decomposes readily when exposed to ordinary atmospheric conditions. therefore it should be handled in either a vacuum apparatus or in a dry box.

Thermal decomposition 
 is stable up to temperatures between 120 °C and 150 °C. The decomposition of  results in a solid phase transition from one crystal form of  to another more stable form. However, the decomposition of gaseous  produces . The activation energy for this reaction is about 40 kcal per mole.

Uranium disilicide. Uranium disilicide is an inorganic chemical compound of uranium in oxidation state +4. It is a silicide of uranium.
There has been recent interest in using uranium disilicide as an alternative to uranium dioxide for
fuel in nuclear reactors. Advantages are higher
percentage of uranium and higher thermal conductivity. A direct replacement of UO2 with U3Si2
should enable a reactor to generate more energy from a set of fuel rods and also provide more "coping time" in the case of a LOCA (Loss of Cooling Accident).

The development of uranium disilicide, uranium nitride, or other high thermal conductivity uranium compound may be critical for the performance of "Accident Tolerant Fuel", a
development effort mandated by the US Department of Energy. This is due to zircalloy having a higher thermal
conductivity than all replacement materials being developed. In particular, SIC-SiC CMC (link), which has several superior material properties to zircalloy for this application, has about five times lower thermal conductivity (varies due to the manufacturing methods used for the fiber and for the matrix) than zircalloy.(refs on SiC-SiC and zircalloy). The lower thermal conductivity means that a reactor using fuel rods with SiC-SiC CMC cladding and conventional UO2 fuel will have to either: 1) Run at a lower power output to keep the fuel the same temperature, or 2) Run with the same power, with the fuel hotter, which means the reactor has less coping time (time to fix what is wrong before something fails). The alternative, enabled by U3Si2 which has about five times better thermal conductivity than UO2 , is expected to be a fuel rod capable of equal power output, slightly better energy output, and longer coping time.

Cao Lãnh Bridge. The  Cao Lãnh Bridge  is a cable-stayed bridge over the Tiền River, a branch of the Mekong River at Cao Lãnh in Vietnam. The bridge is one of three components of the planned Central Mekong Delta Connectivity Project (CMDCP). The other two components are the Vàm Cống Bridge at Vàm Cống and the 4 lane expressway connecting the two bridges. The Cao Lanh Bridge was inaugurated on 27 May 2018.

Design
The cable-stayed bridge is  long with a central span of  and a maximum clearance above high water level of . The total length of the bridge, including the approach viaducts, is  with spans of 17 x 40 + (150+350+150) + 17x40 (m). It has H-shape towers  high, cast in situ concrete girder superstructure with a double-plane of cables in a semi-fan type configuration. It carries four lanes for traffic. The maximum speed on the bridge will be 80 km/h.

The objective of the Central Mekong Delta Connectivity Project is to encourage the economic and social development of the Cửu Long Delta area. The project was developed with the financial assistance from the Asian Development Bank (ADB) and the Government of Australia. It is jointly funded by the governments of Australia and Vietnam, and the ADB. The bridge was the largest overseas assistance project undertaken by the Australian government costing A$160 million.

Construction
The groundbreaking ceremony for the Cao Lanh Bridge, was held on 19 October 2013 and attended by senior officials from the Vietnamese and Australian Governments and the Asian Development Bank (ADB). The bridge was expected to be completed after 43 months in mid-2017 but was delayed.

The opening of the bridge, held on 27 May 2018, was attended by Vietnam Deputy Prime Minister Trinh Dinh Dung, Australian Foreign Minister Julie Bishop, Vietnam Minister for Transport Nguyen Van The, ADB Country Director Eric Sidgwick and senior officials from ministries, cities and provinces.

Adaptiv. Adaptiv is an active camouflage technology developed by BAE Systems AB to protect military vehicles from detection by far infrared night vision devices, providing infrared stealth. It consists of an array of hexagonal Peltier plates which can be rapidly heated and cooled to form any desired image, such as of the natural background or of a non-target object. Its goal is to develop stealth ground vehicles.

Technology

In 2011, BAE Systems announced their Adaptiv infrared military camouflage technology, likening it to "a thermal TV screen". It uses about 1000 hexagonal panels to cover the sides of an armoured vehicle such as a tank or personnel carrier. Infrared cameras continuously gather thermal images of the vehicle's surroundings. The Peltier plate panels are rapidly heated and cooled to match either the temperature of the background, such as a forest, or one of the objects in the thermal cloaking system's "library" such as a truck, car or large rock. The system is able to gather and display thermal images while the vehicle is moving. The result is to "cloak" the vehicle from detection by heat-detecting night vision devices (thermographic camera systems).

For crypsis, the panels can display an infrared image of the vehicle's background; this can be updated as the vehicle moves. For mimesis, an image of a chosen object, such as a car, can be retrieved from Adaptiv's library and superimposed on the background. The illustration shows Adaptiv mimicking a four-wheel drive car, using part of the panel, while the rest of the panel is cryptic, imitating the natural background. The technology is said to reduce the range at which a vehicle would be detected to less than 500 metres.

The panels forming Adaptiv's pixels are hexagons approximately 5.5 inches (14 cm) wide. They are robust, contributing to the armour of the vehicle that carries them. The system allows its operator to "grab" a thermal image from a vehicle or other object for display.

Adaptiv was developed by BAE Systems AB's survivability programme at  Örnsköldsvik, Sweden, initially for Combat Vehicle 90 infantry fighting vehicles. The company has developed a lighter version which has been tested on helicopters. A version for ships could in principle use larger panels. A somewhat similar system was prototyped to an early stage by the Israeli company Eltics in 2010.

Bombardier Talent 2. The Talent 2 is a electric multiple unit manufactured by Bombardier Transportation. The train began production in 2008 and first entered service with Deutsche Bahn in 2011.

Despite having the same name as the original Talent, designed by Waggonfabrik Talbot and later acquired by Bombardier, for the most part it does not share technical details with that train, except for the rounded sides and doorways. The crash-optimized design of the cab ends have led to the units acquiring the nickname "Hamsterbacke" (Hamster Cheeks). The Talent 3 is the successor of the Talent 2.

Kärcher RC3000. The Kärcher RC 3000 was a robotic vacuum cleaner created by Kärcher in 2002, and manufactured until January 2015. Unlike other robotic vacuum cleaners of the time, the RC 3000 was designed with a self-service station that allows owners to keep their robots running (without human intervention) for longer periods of time. The service station, containing a paper bag, accomplishes this by acting as the collection point for the dirt and dust swept up by the robot.

Like other robots, the RC 3000 is equipped with basic sensors to aid in general operation, such as fall sensors (to prevent the robot from falling down stairs) and "jamming sensors" (to prevent the robot from getting stuck on obstacles). Designed to work on most carpets and hard floors, the manufacturer has noted that the robot may have problems operating on very high pile carpets (>20 mm).

Description

RC3000 unit 
The RC 3000 is 285x105 mm (DxH) and is two kilograms in weight. The units produced by Kärcher are yellow in coloration with IR sensors mounted beneath translucent plastic strips (used to find the service station) on the top of the unit. The unit has a bumper strip extending around the unit. A single ventilation port is visible on the back of the unit.

Turning the unit over reveals the two wheels on the underside of the unit in addition to the roller brush. A service port is accessible by lifting two levers on the underside of the unit. This service port gives access to the air filter and 0.2 litre dirt bin.

RC4000 unit 
A short lived RC4000 was manufactured from 2011 to 2015, effectively a light grey version of the RC3000.

Self Service Station 
The service station is much larger than the physical unit at 500x250x230 mm (LxBxH). The station weighs 5.8 kilograms and is designed for use with 220-240 VAC power sources. The base unit contains the collection bag and suction unit (for robot service). Additionally, the service station houses the scheduling and operation buttons for the unit, unlike other robots like the Neato and Roomba which have scheduling and operation buttons built into the robot.

Cellulose diacetate. Cellulose diacetate, sometimes called diacetate, is a synthetic polymer made by treating cellulose with acetic acid. It consists of two acetyl functional groups on each unit of D-anhydroglucopyranose of the cellulose molecule. It was first developed in the United States.

It is fragile since it is based on cellulose. When cellulose diacetate deteriorates, it shrinks and releases acetic acid causing  vinegar syndrome.

Cellulose diacetate has been used to make fabrics, membranes, filaments, and many consumer products. From 1922 to 1957 it was used to make film stock, mainly in smaller formats such as 8 mm, 16 mm, 35 mm, and 70 mm. It has also been used in seed coating applications.

In photography, a film substrate made from cellulose diacetate is called safety film.

Cellulose diacetate is hydrophilic and biodegradable.

Tetrasilane. Tetrasilane is a silane with the structure formula SiH3–(SiH2)2–SiH3. It is the silane analog of butane.

Preparation 
Tetrasilane can be prepared by reacting magnesium silicide (Mg2Si) with acids like 20% phosphoric acid in 50–60 °C.

The reaction can produce silanes up to n=15. The reaction of magnesium silicide with 25% hydrochloric acid produces 40% monosilane, 30% disilane, 15% trisilane, 10% tetrasilane and 5% higher silanes. The mixture can be separated by fractional distillation.

In addition, higher silanes can also be obtained by discharges monosilane:

Properties
Tetrasilane is a colourless, pyrophoric liquid that has a disgusting odour. Even below 54 °C, it will still spontaneous combust. It is even more unstable than trisilane, slowly decomposing at room temperature, releasing hydrogen and forming shorter chain silanes.

Reactions
Photochemical disproportionation of tetrasilane will produce 3-silylpentasilane and disilane.

With the presence of aluminium chloride, heating tetrasilane in xylene will allow isomerization to isotetrasilane.
