9,10-Dibromoanthracene. 9,10-Dibromoanthracene is an organic chemical compound containing anthracene with two bromine atoms substituted on its central ring. It is notable in that it was the first single molecule to have a chemical reaction observed by an atomic force microscope and scanning tunneling microscopy.

Production
Ian M. Heilbron and John S. Heaton were the first to synthesize this in 1923 in England.

Properties
9,10-Dibromoanthracene is electroluminescent, giving off a blue light.

Reactions
The carbon–bromine bonds can be fragmented in two successive steps by voltage pulses from tip of a scanning tunneling microscope. The resulting carbon radicals are stabilized by the sodium chloride substrate on which the 9,10-dibromoanthracene reactant was placed. Further voltage pulses cause the diradical to convert to a diyne (or back again) via a Bergman cyclization reaction.

K9 glass. K9 glass, sometimes referred to as K9 crystal, is a variety of optical borosilicate crown glass.  The letter "K" is a reference to the German word for "crown" (Krone) and the number 9 refers to the lead oxide content of the glass (9%).  K9 glass has high optical clarity, and is used in many contexts requiring this characteristic.  It has been regarded as a difficult-to-cut material because of its superior mechanical properties.  It has an elastic modulus per pascal of 8x1010, a Poisson's ratio of 0.21, and a density of 2510 kilograms per cubic meter (less dense than most other leaded glass).  Its refractive index is 1.517 at 590 nm wavelength (compared to 1.523 for crown glass (soda-lime)  and 1.618 for 45% leaded glass) Its clarity (90% transmission at 590 nm), combined with low cost have made it desirable for chandeliers, lasers, telescopes, etc.

K9 is produced in large quantities by China, which sells it at a price far below higher-quality well-known glass manufacturers such as Swarovski.  A similar product to K9 (but without lead) is BK7.

London Power Tunnels. London Power Tunnels is a project by National Grid to reinforce the electricity transmission network in London, UK, by constructing more than 60 km of new deep-level tunnels carrying high-voltage cables.

The new network of tunnels replaces a series of ageing power cables, most of which were buried directly beneath roads. These were becoming unreliable, difficult to maintain without disrupting traffic and were unable to meet future demand for electricity. The new tunnels allow the power cables to be upgraded and maintained without disruption to traffic and residents on the surface.

The project is divided into two phases: the first phase involved constructing tunnels connecting substations at Wimbledon, Hackney and Willesden and was completed in 2018. The second phase involves linking Wimbledon substation with Crayford and is expected to be completed in 2026.

Phase 1 

The first phase involved constructing 32 km of tunnels linking substations from Wimbledon in the south west to Hackney in north east of London, at a cost of £1 . The 3–4 m diameter tunnels were dug by tunnel boring machines and run 20–60 m below street level. The tunnels were constructed by a joint venture between Costain Group and Skanska.

This phase linked Wimbledon and Hackney to substations at Willesden, St John's Wood, St Pancras, and Islington. It also involved the construction of two new substations at Seven Sisters Road in Highbury, and at Kensal Green, to feed traction power to Crossrail.

As well as the main  power transmission circuits for the National Grid, the tunnels also carry  circuits from Islington substation to St Pancras and Seven Sisters Road, forming part of the London power distribution network operated by UK Power Networks.

Construction began in February 2011 and the first section was energised five years later in February 2016. The project was officially opened by Charles III (then Prince of Wales) in February 2018.

Phase 2 
Construction of the second phase (known as LPT2) started in spring 2020 and will span 32.5 km from Wimbledon to Crayford in south-east London, connecting to existing substations at New Cross, Kidbrooke, and Hurst. Access shafts will be constructed at King's Avenue in Brixton and at Eltham, and a new substation will be constructed at Bengeworth Road in Lambeth.

The tunnels will be between 3–3.5 m in diameter, 10–63 m below street level, with most being around 30 m deep. The project was initially planned to cost £750m, and is now expected to cost £1 billion.

The contract for the second phase was awarded to a joint venture between Murphy Group and Hochtief in December 2019. Construction on this phase started in May 2021, tunnelling was completed in October 2023, and the project is expected to become operational in 2026.

Elstree to St. John's Wood Cable Tunnel. The Elstree to St. John's Wood Cable Tunnel, known as The London Connection during construction, is a 20 km long, 3m wide tunnel beneath northwest London. Constructed between 2001 and 2005, the tunnel carries high voltage transmission lines from Elstree substation in Hertfordshire to Lodge Road sub station in Westminster at a depth of 20m below street level.

The tunnel runs beneath the A5 road for the majority of its length, and houses a single 400 kV power transmission circuit with a rated capacity of 3700 A. There is provision for a second circuit to be installed in the future.

A remotely operated, battery powered monorail system runs along the tunnel, allowing the cables to be inspected remotely using infrared cameras.

Scaling of innovations. Scaling of innovations is an industrial and social process that leads to widespread use of an innovation.  The potential of a production system to undergo this process is called its "scalability".  Scaling is regarded the last step after the discovery, proof of concept and piloting of an innovation. In business it is often used as maximizing operational scale of the product. This technology, or project-focused scaling takes products and services as the point of departure and wants to see those to go scale. In the public sector, and for example in development aid, the desired impact is the point of departure and whatever leads to more impact is scaled (usually in the form of a range of innovations). However, some authors recognize that the public sector often uses the business way of scaling to reach impact, leading to disillusionment and doing more harm than good. Sometimes, scaling is seen as a process towards sustainable systems change at scale, where sustainability, systems change and responsible scaling are just as important as “reaching many”.

Dimensions 
Although scaling is often associated only with “more, better, bigger” it is important to consider that it has three dimensions:
 Scaling out involves expanding the geographical spread, or reach, of a technology or practice over time. It is associated with quantitative processes like replication, expansion, extension, adoption, dissemination, transfer of technology, mainstreaming, and multiplication .
 Scaling up entails creating the necessary social and institutional preconditions for scaling out to happen efficiently. It is associated with qualitative processes like transition, institutionalizations, transformation, integration, evolution, and development.
 Scaling deep deals with the notion that sustainable and transformative impact is achieved only “when people´s hearts and minds, their values and cultural practices and the quality of relationships they have are transformed”, to make the use of the innovation the new routine.

Tools 
The first toolkit on scaling innovations was made available for practitioners in 2006 by Cooley and Kohl. It was called the Scaling Up Management (SUM) Framework, it was subsequently refined and expanded in Editions 2 and 3, both of which include the MSI Scalability Assessment Tool. USAID adapted the latter in 2018 to the Agricultural Scalability Assessment Tool (ASAT). Other donors such as the International Fund for Agricultural Development (IFAD), the World Health Organization (WHO), and GIZ have also developed toolkits. Most recently, the International Maize and Wheat Improvement Center (CIMMYT) and the PPPLab developed the Scaling Scan. All these frameworks assign the difficulty of scaling innovations to a lack of clarity about what is required to achieve sustained results beyond smaller pilot programs. The tools help simplify and explain the complexities of scaling and guide users to systematically think through key elements, ingredients, or success factors.

Thames Cable Tunnel. The Thames Cable Tunnel, also known as the Tilbury – Gravesend Cable Tunnel, is a tunnel carrying high-voltage electrical transmission lines beneath the lower River Thames between Tilbury and Gravesend. It remains the furthest tunnel downstream on the Thames.

Completed in 1970 at a cost of around £3 million (equivalent to £ million in ) by the Central Electricity Generating Board, the tunnel carries 400 kV transmission cables between substations at Tilbury and Kingsnorth as part of the National Grid. The tunnel is approximately  deep, and was one of the first tunnels in the UK to be lined with pre-cast concrete segments rather than cast iron. A tunnel was chosen due to the high costs of building an overhead transmission line at this point in the river.

In September 2023, National Grid announced that they were planning to retire the Thames Cable Tunnel, as it was approaching the end of its useful life. The Grain to Tilbury project aims to construct a new tunnel to replace it.

2-Picolylamine. 2-Picolylamine is an organic compound with the formula H2NCH2C5H4N.  A colorless liquid, it is a common bidentate ligand and a precursor to more complex multidentate ligands such as tris(2-pyridylmethyl)amine.  It is usually prepared by hydrogenation of 2-cyanopyridine.  One such complex is Baratta's catalyst RuCl2(PPh3)2(ampy) (ampy = 2-picolylamine) for transfer hydrogenation.  Salts of the complex [Fe(pyCH2NH2)3]2+ exhibit spin crossover behavior, whereby the complex switches from high to low spin configurations, depending on the temperature.

Safety
The oral  in quail is low, being 750 mg/kg.
