Dichlorooctylisothiazolinone. Dichlorooctylisothiazolinone, DCOIT or  DCOI, is the organic compound with the formula SC(Cl)=C(Cl)C(O)NC7H15.  It is a white solid that melts near room temperature. It is an isothiazolinone, a class of heterocyclic compounds used as biocides. DCOIT has attracted attention as an antifouling compound.  It is a replacement for organotin compounds that have been largely banned for causing environmental damage. DCOIT however is itself controversial.

Safety

Isothiazolinones are highly bioactive and have attracted scrutiny for causing contact dermatitis.

The building has received a LEED Gold energy label.

Design
Situated by the Keelung River in the fast-emerging southeastern district of Nangang in Taipei, Lè Architecture aims to convey traditional Taiwanese culture of roundness, strength and elegance with a modern twist by using an egg-shaped exterior design, which was inspired from the small pebbles in the Keelung River. Aiming to minimise energy demands, the building employs several sustainable features, such as a green façade that can lower the interior temperature by acting as a shade to reduce heat gain. Furthermore, natural light is allowed to enter the building by the use of vertical aluminium fins to control the amount of sunlight streaming through the windows. The trees planted in the exterior aims to act as air filters for the building.

Itoh Emi 30. The Itoh Emi 30 was a small, single-engined, sports biplane built in Japan in 1922. Though it attracted attention by being the smallest Japanese aircraft of its time, the sole example was mostly used as an aerobatics trainer.

Design and development

When it was first displayed in 1922 the Emi 30, a single seat civil sports aircraft, was the smallest aircraft in Japan. After World War I Itoh had followed design developments in both Europe and the US and had explored these trends with their own designs. The Emi 29, which enclosed its two passengers in a cabin, was the first Japanese design to follow the limousines of the west. The Emi 30 was the first Japanese aircraft influenced by a western interest in small sports aircraft.

The Emi 30 had a wooden structure and was fabric-covered.  It was a single bay biplane with wings braced by parallel pairs of streamlined interplane struts. The lower wing, which had a slightly greater span than the upper one, was mounted on the lower fuselage longerons and the centre section of the upper wing was held over the fuselage by outward leaning, parallel cabane struts from the upper longerons. The two spar wings had thick airfoil profiles compared to most contemporary biplanes. There were inset ailerons on the upper wing.

It was powered by an Itoh built,  radial engine. The Itoh 11 used the cylinders and pistons from a Japanese-built Renault engine, joined to a new crankshaft and crankcase. Its two-bladed propeller had a domed spinner. The Emi 30 was flown from an open cockpit under the upper wing, with a streamlined headrest which merged into a slender rear fuselage. The tail was conventional, with a tailplane mounted on top of the fuselage and braced from below, and a generous fin and balanced rudder with an overall rounded but pointed profile.

The Emi 30's landing gear had wheels on a single axle, its ends supported by V-struts from the lower fuselage longerons.

Operational history

It was first seen in public at an exhibition in July 1922, where it was awarded a silver plaque for innovation. The date of the first flight is not known but it was developed in a program flown by Seizo Okhura and later used as an aerobatics trainer by the newly renamed Itoh Aeroplane Manufacturing Works.  In March 1924 it was displayed on the roof of a Tokyo department store where it was on sale for 5,000 yen but its later history is not known. There is no firm evidence that more than one was built.

Background
ULAQ, a derivation of  for government official envoy, is the first of a series of AUSVs of Turkey, which was developed for the Turkish Navy by Ares Shipyard and Meteksan Defense Systems. The design studies completed by August 2020, and the prototype was launched on 12 February 2021 in Antalya. It was planned that firing tests with guided missiles of Roketsan would be carried out by March 2021. On 25 May 2021, the vessel successfully completed its first firing test. The Roketsan Cirit missile fired from the vessel destroyed the target with pinpoint accuracy.

Characteristics
The vessel can be deployed from combat ships. She can be controlled remotely from mobile vehicles, headquarters, command centers and floating platforms. It serves in missions such as reconnaissance, surveillance and intelligence, surface warfare, asymmetric warfare, armed escort and force protection, and strategic facility security. It is planned that the vessel will operate jointly with other AUSVs, armed UAVs and aircraft, and instantly transmit images and other data she obtains to provide major benefits to the operational capability of the Turkish Armed Forces.

The ULAQ AUSV will come in 6 different variants each with its own type of mission and armament

Made of advanced composite material, the boat is  long and has a payload capacity of . She has a range of  and a cruise speed of . She is operable at rough sea (sea state 5:  wave height).

Materials Project. The Materials Project is an open-access database offering material properties to accelerate the development of technology by predicting how new materials–both real and hypothetical–can be used. The project was established in 2011 with an emphasis on battery research, but includes property calculations for many areas of clean energy systems such as photovoltaics, thermoelectric materials, and catalysts. Most of the known 35,000 molecules and over 130,000 inorganic compounds are included in the database.

Dr. Kristin Persson of Lawrence Berkeley National Laboratory founded and leads the initiative, which uses supercomputers at Berkeley, among other institutions, to run calculations using Density Functional Theory (DFT). Commonly computed values include enthalpy of formation, crystal structure, and band gap.  The assembled databases of computed structures and properties is freely available to anyone under a CC 4.0 license and was developed with ease of use in mind.  The data have been used to predict new materials that should be synthesizable, and screen existing materials for useful properties.

The project can be traced back to Persson's postdoc research at MIT in 2004, during which she was given access to a supercomputer to do DFT calculations. After joining Berkeley Lab in 2008, Persson received the necessary funding to make the data from her research freely available.

Plutonium(III) bromide. Plutonium(III) bromide is an inorganic salt of bromine and plutonium with the formula PuBr3. This radioactive green solid has few uses, however its crystal structure is often used as a structural archetype in crystallography.

Crystal structure

The PuBr3 crystal structure was first published in 1948 by William Houlder Zachariasen. The compound forms orthorhombic crystals, a type of square antiprism, within which the Pu atoms adopt an 8-coordinate bicapped trigonal prismatic arrangement. Its Pearson symbol is oS16 with the corresponding space group No. 63 (in International Union of Crystallography classification) or Cmcm (in Hermann–Mauguin notation). The majority of trivalent chloride and bromide salts of lanthanide and actinides crystallise in the PuBr3 structure.

Jean-Philippe Ansermet. Jean-Philippe Ansermet (; born ) is a Swiss physicist and engineer and a professor at École Polytechnique Fédérale de Lausanne. His research focuses on the fabrication and properties of nanostructured materials as well as spintronics.

Career 
Jean-Philippe Ansermet graduated from École Polytechnique Fédérale de Lausanne with a degree in physics in 1980. He then pursued a PhD at the University of Illinois at Urbana-Champaign, developing NMR spectroscopy for catalysis research and defending his thesis in 1985. He then continued his research on surface NMR as a postdoc at the same institution until 1987, when he was named group leader for the Swiss chemical company Ciba-Geigy, working on composite materials and charge-transfer salts. In 1992, he was named professor of experimental physics at EPFL, where he was promoted to full professor in 1995 and named head of the physics section in 2007. There, he teaches classical mechanics as well as thermodynamics to undergraduate and graduate students.

He was a member of the executive committee of the European Physical Society from 1993 to 1998, and the president of the Swiss Physical Society from 2002 to 2006.

Research 
Ansermet heads the Laboratory of the Physics of Nanostructured Materials at the Institute of Physics of EPFL. Research in his lab focuses on spintronics and novel magnetic resonance methods, including sub-THz instrumentation.

The laboratory of Ansermet characterized giant magnetoresistance with current driven perpendicular to the interfaces of Co/Cu multilayers before large collaborations could achieve the same through lithography. It also participated in the discovery that a current can flip the magnetization of a nanostructure via the spin-transfer torque. The lab demonstrated the concept of a heat-driven spin torque in ferromagnetic metals. Using thermodynamics, the laboratory also predicted and demonstrated a heat-driven spin torque in insulating ferromagnet.

The laboratory of Ansermet studies Dynamic Nuclear Polarization (DNP) as a way to enhance signals in surface-NMR experiments, requiring excitation in the sub-THz domain. This constraint led to the development of DNP instruments by the LPMN and its collaborators and the creation the Swiss start-up Swissto12. Collaboration between the Swiss Plasma Center at EPFL and the LPMN led to the construction of a gyrotron. The laboratory further showed that this equipment can induce resonance in antiferromagnets, thus expanding the field of spintronics.

Kevin Escoffier. Kevin Escoffier is a French professional sailor born on 4 April 1980 in Saint-Malo, France and a resident of Lorient. He is an offshore sailor who has won the 2018 Volvo Ocean Race as a bowman onboard DongFeng and competed in the 2020–2021 Vendée Globe aboard PRB. In 2022-23, he initially skippered Holcim-PRB in The Ocean Race, before leaving the team amid a sexual misconduct probe. He is a member of the yacht club SN Baie St. Malo.

Biography
He studied Engineering for 3 years at EPF in Paris, 2 years at the École Polytechnique de Montréal and 8 months at the University of Maryland and now specializes in composite engineering. One of his first projects was being involved in the development of Multi 50 class "Crêpes Whaou! 2", which was built for his father Franck-Yves Escoffier, also an offshore sailor. This boat was launched in April 2005 and in November of that year Escoffier and his father won class in the Transat Jacques Vabre. We was involved in various IMOCA projects for other skippers, and has headed up Team Banque Populaire's design office.

2020–2021 Vendée Globe Rescue 
While competing in the 2020–2021 Vendée Globe his IMOCA 60 PRB hull broke in half, sinking quickly in the Southern Ocean. Describing the speed of the incident he said “I didn’t have time to do anything, I just had time to send a message to my team. I’m sinking, I’m not joking. MAYDAY.” He later recalled how the boat folded in half.

The race director sent fellow competitor Jean Le Cam to the area who found Escoffier in his life raft, but lost contact while preparing to recover him. More competitors were sent to help with the search but Jean Le Cam found Escoffier for the second time several hours later and took him on board.

The rescue got extensive coverage with French President Emmanuel Macron getting in contact with Escoffier and Jean Le Cam. Escoffier later described the way the boat folded in 90 degrees and the very limited time he had to abandon ship, and how him carrying a personal AIS beacon helped save his life.

Blazer 23. The Blazer 23 is a Canadian trailerable sailboat that was designed by Bruce Kirby as racer-cruiser and first built in 1988.

The Blazer 23 is a cruising development of the Sonar, using the same hull design, but with a larger cabin with ports and a commensurately smaller cockpit, but slightly more sail area. It is very similar to the Kirby 23.

Production
The design was built by Ontario Yachts in Canada, starting in 1988, but it is now out of production.

Design
The Blazer 23 is a recreational keelboat, built predominantly of fibreglass, with wood trim. It has a fractional sloop rig, a raked stem, a slightly reverse transom, a skeg-mounted rudder controlled by a tiller and a fixed fin keel. It displaces  and carries  of lead ballast.

The boat has a draft of  with the standard keel.

The boat is normally fitted with a small  outboard motor for docking and manoeuvring.

The design has sleeping accommodation for four people, with a double "V"-berth in the bow cabin and two straight settees in the main cabin. The galley is located on both sides, just aft of the bow cabin. The galley is equipped with a two-burner stove on the starboard side and a sink on the port side. The head is located under the bow cabin "V"-berth. Cabin headroom is .

For safety the design is equipped with foam flotation.

The design has a PHRF racing average handicap of 180 and a hull speed of .

Operational history
In a 2010 review Steve Henkel wrote that the boat provides, "exceptionally spritely performance in light and moderate air. Foam flotation for safety is also a plus. Worst features: Low profile and an extra-long cockpit result in a short, low cabin with significantly less accommodation space than the Blazer's comp[etitor]s. Due to her deep draft and deep, nonfolding rudder, using a hoist rather than a ramp for launching is a virtual necessity."

1-O-Acetyl-2,3,5-tri-O-benzoyl-β-D-ribofuranose. {{DISPLAYTITLE:1-O-Acetyl-2,3,5-tri-O-benzoyl-β-D-ribofuranose}}

1-O-Acetyl-2,3,5-tri-O-benzoyl-β-D-ribofuranose, also called β-D-ribofuranose 1-acetate 2,3,5-tribenzoate, is a ribose-derived compound used in nucleoside synthesis.

Industrial synthesis 
In the patented formation of 1-O-acetyl-2,3,5-tri-O-benzoyl-β-L-ribofuranose, a reactor containing thionyl chloride (5 ml) and methyl alcohol (100 ml) is stirred at 0–5 °C for 10 to 15 minutes. After this period, 10 g (ratio-wise) of ribose is added to the flask. The flask is then stirred and maintained at its temperature for 8 hours. During this period, a methylation reaction will occur on the ribose. After the 8-hour period of methylation, the flask will be filled with 150 ml of ethyl acetate, 5 ml pyridine, and 30 g potassium carbonate. The flask will then be heated to 60–70 °C. Over 99 minutes at this temperature, 30 ml of the chemical benzyl chloride will be intermittently dripped into the flask to react with the ribose directly. After this period, the flask will be left for 4 to 8 hours to continue reacting. The subsequent solid nonacetylated ribose benzyl glycoside will be isolated by neutralizing the flask liquid by addition of sulfuric acid, then suction of the precipitate (the non-acetylated ribose benzyl glycoside). The benzyl ribose glucoside will then be put into a separate flask. In this flask, glacial acetic acid and acetic anhydride will be mixed with the benzyl glycoside under a maintained temperature from −5 to 5 °C for 5 hours. The 1-O-acetyl-2,3,5-tri-O-benzoyl-β-L-ribofuranose will be the product yielded after recrystallization with ethyl alcohol and isolation by known filtering methods.

Use in artificial nucleotide synthesis 
1-O-Acetyl-2,3,5-tri-O-benzoyl-β-D-ribofuranose is further reacted with trimethylsilyl trifluoromethanesulfonate (TMSOTf) under the silyl-Hilbert–Johnson reaction and deprotected by an acid or base to form a pure artificial nucleotide.
