Zinc diphosphide. Zinc diphosphide (ZnP2) is an inorganic chemical compound. It is a red semiconductor solid with a band gap of 2.1 eV. It is one of the two compounds in the zinc-phosphorus system, the other being zinc phosphide (Zn3P2).

Synthesis and reactions
Zinc diphosphide can be prepared by the reaction of zinc with phosphorus.
2 Zn  +  P4   →  2 ZnP2

Structure
ZnP2 has a room-temperature tetragonal form that converts to a monoclinic form at around 990 °C. In both of these forms, there are chains of P atoms, helical in the tetragonal, semi-spiral in the monoclinic.

This compound is part of the Zn-Cd-P-As quaternary system and exhibit partial solid-solution with other binary compounds of the system.

Safety
ZnP2, like Zn3P2, is highly toxic due to the release of phosphine gas when the material reacts with gastric acid.

HMS Erica (K50). HMS Erica was a  that served in the Royal Navy and was built by Harland and Wolff in 1941. She was named after Erica. Commissioned in 1940 and sunk by a mine on 9 February 1943.

Design and description
In early 1939, with the risk of war with Nazi Germany increasing, it was clear to the Royal Navy that it needed more escort ships to counter the threat from Kriegsmarine U-boats. One particular concern was the need to protect shipping off the east coast of Britain. What was needed was something larger and faster than trawlers, but still cheap enough to be built in large numbers, preferably at small merchant shipyards, as larger yards were already busy. To meet this requirement, the Smiths Dock Company of Middlesbrough, a specialist in the design and build of fishing vessels, offered a development of its 700-ton,  whale catcher Southern Pride. They were intended as small convoy escort ships that could be produced quickly and cheaply in large numbers. Despite naval planners' intentions that they be deployed for coastal convoys, their long range meant that they became the mainstay of Mid-Ocean Escort Force convoy protection during the first half of the war. The original Flowers had the standard RN layout, consisting of a raised forecastle, a well deck, then the bridge or wheelhouse, and a continuous deck running aft. The crew quarters were in the foc'sle while the galley was at the rear, making for poor messing arrangements.

The modified Flowers saw the forecastle extended aft past the bridge to the aft end of the funnel, a variation known as the "long forecastle" design. Apart from providing a very useful space where the whole crew could gather out of the weather, the added weight improved the ships' stability and speed and was retroactively applied to a number of the original Flower-class vessels during the mid and latter years of the war.

Construction and career
Erica was laid down by Harland and Wolff at their shipyard at Belfast, on 22 February 1940 and launched on 18 June 1940. She was commissioned on 9 August 1940.

On 9 February 1943 a convoy of five empty merchant ships sailed from Benghazi at 0200 hours for Tobruk and Alexandria under escort by the corvette HMS Erica, the armed trawlers HMS Burra and HMSAS Southern Maid and two M.Ls. At 1550 hours, in position 32°48'5 N, 21°06E, off Derna, Libya, HMS Erica, who was investigating an A/S contact, struck a mine and sank. It was at first thought to have been a torpedo but ML's from Tobruk and Benghazi carried out an A/S search of the area but without result, and from subsequent investigation it is evident that she struck a mine in a field laid by HMS Rorqual some time ago. HMSAS Southern Maid picked up all officers and seventy-one ratings. Casualties were one rating missing and another who died of wounds.

Pipistrel Nuuva V300. The Pipistrel Nuuva V300 is an unmanned hybrid-electric VTOL cargo aircraft currently under development by Pipistrel and projected to be released in 2023. The aircraft has eight electric motors driving propellers providing lift as well as a single internal combustion engine driving a propeller providing thrust. The company claims that the aircraft will be able to operate with a typical cargo weight of  and a typical range of . In October 2020 the company announced that the aircraft would implement a Honeywell fly-by-wire system.

Design and development
The aircraft is a tandem wing design, with the rear wing of a larger wingspan than the front one. Both wings are attached to a fuselage, which features a large front door on the nose to access the internal  cargo hold and an internal combustion engine with a pusher propeller at the rear end.

A pair of booms, one at each side of the aircraft, connect both wings and serve primarily to support eight electric engines intended for vertical propulsion. Each electric engine turns a 2-blade propeller.

In October 2020 the company announced that the aircraft would implement a Honeywell fly-by-wire system with triple redundancy for the autonomous flight control of the vehicle. The flight itself would be autonomous but managed remotely by a ground-based operator. In January 2025, the company announced the ground control station was developed in collaboration with Textron Systems.

Pipistrel is planning for the Nuuva V300 to enter service in the second half of 2023. A smaller variant, the Nuuva V20, is expected to start operating as early as 2021 and would carry payloads of up to .

On 31 January 2025 Pipistrel announced the first hover flight of the Nuuva V300 in Gorizia, Italy.

Cadmium phosphide. Cadmium phosphide (Cd3P2) is an inorganic chemical compound. It is a grey or white bluish solid semiconductor material with a bandgap of 0.5 eV. It has applications as a pesticide, material for laser diodes and for high-power-high-frequency electronics.

Synthesis and reactions
Cadmium phosphide can be prepared by the reaction of cadmium with phosphorus:
6 Cd  +  P4   →  2 Cd3P2

Structure
Cd3P2 has a room-temperature tetragonal form.

The crystalline structure of cadmium phosphide is very similar to that of zinc phosphide (Zn3P2), cadmium arsenide (Cd3As2) and zinc arsenide (Zn3As2). These compounds of the Zn-Cd-P-As quaternary system exhibit full continuous solid-solution.

Applications 
Over the last decade, interest in cadmium phosphide as a source for fast, near-IR emission has grown due to the development of cadmium phosphide quantum dots. Literature has demonstrated that these quantum dots possess tunable emission between 700 nm to 1500 nm.  A recent paper investigated the effect of surface passivation on these quantum dots and showed that cadmium phosphide quantum dots may have an intrinsic band-edge relaxation time less than 100 ns.

Safety 
Like other metal phosphides, it is acutely toxic when swallowed due to the formation of phosphine gas when it reacts with gastric acid. It is also carcinogen and dangerous for the skin, eyes and other organs in a large part due to cadmium poisoning.

Tokyo Koku Aiba-Tsubame. The Tokyo Koku Aiba-Tsubame or Tokyo Aviation Aiba-Swallow  was a 1930s Japanese civil transport with seats for three passengers. It was intended to be cheap to produce so, although its fuselage was a new design, its wings and undercarriage were those of another Japanese aircraft. Two were built and flew taxi services and joyrides.

Design and development

Tokyo Aviation was formed in 1936 from the 1935 Tokyo Air Transport Co., founded by Tamotsu Aiba. It aimed to produce low cost civil transport and trainer aircraft. The Aiba-Tsubame, its first design, was a three passenger aircraft with a new fuselage and a Japanese engine, married to the wings, tail and undercarriage of the Yokosuka Navy Type 3 Primary Trainer, a Japanese update of the Avro 504 with revised empennage and undercarriage. It was funded by the Imperial Flying Association.

A biplane, its two bay wings were rectangular in plan out to rounded tips, braced by two parallel pairs of interplane struts on each side and supported over the fuselage with near-vertical, parallel pairs of short cabane struts. There were externally interconnected ailerons on upper and lower wings, reaching from near the wingtips across the outer bay.

Its  Gasuden Jimpu Kai-1 seven cylinder radial engine was mounted in the nose of a deep, flat-sided, fuselage with curved upper decking. Structurally the fuselage was entirely wooden. It was flown from an open cockpit under the leading edge of the upper wing. The cabin seated three passengers who, in the prototype (Aiba-Tsubame 6), had windows over the wing. The second aircraft, the Aiba-Tsubame 7, had a longer cabin with an extra window behind the trailing edge.

The Aiba-Tsubame had a tail with a cropped, triangular profile fin which carried a full, rounded, balanced rudder very distinct from the comma form of most 504s' rudders. The broad, rectangular plan horizontal tail was very similar to that of the 504.

Its undercarriage was of the single axle type, with landing legs to the inner wing and rearward drag struts meeting at the fuselage centre-line.

The Aiba-Tsubame 6 was completed in September 1936, followed by the Aiba-Tsubame 7 in December. They were the only examples built. Despite the similarities of name, the Aiba-Tsubame 8 Trainer was a different design, a two seat, single bay biplane.

Operational history

Based at Haneda Airport, the two Swallows were used as taxis and for sight-seeing flights. They proved reliable, safe in flight, stable and easy to control, becoming the most familiar of Haneda's aircraft.

Variants
Aiba-Tsubame 6 First airframe.
Aiba-Tsubame 7 As Aiba-Tsubame 6 but with an internally extended cabin and slightly (about ) heavier.
