3,3-Bis(azidomethyl)oxetane. 3,3-Bis(azidomethyl)oxetane (BAMO) is a oxetane monomer used in energetic propellant binders and plasticizer. It is frequently used as a copolymer to improve the physical properties of more commonly used polymers and to give them energetic properties.

Preparation 
BAMO is made by reacting BCMO with sodium azide in an alkaline solution. Tetrabutyl ammonium bromide is used as a phase-transfer catalyst in the reaction.

PolyBAMO can be made by mixing boron trifluoride diethyl etherate and BAMO in trimethylolpropane. The polymerization of BAMO destroys the oxetane ring, but the azide groups remain intact.

NESS Energy Project. The NESS Energy Project is an incinerator currently in full operation in Aberdeen, UK. It is situated in East Tullos Industrial Estate on a site formerly used for gas storage.

History 
In February 2022, construction workers staged a walkout in a dispute over unpaid wages.

Operation 
The facility is designed to burn up to 150,000 tonnes of material per year, consisting of non-recyclable waste from Aberdeen City Council, Aberdeenshire Council, and Moray Council.

The facility will be operated by Acciona, who were awarded a contract worth approximately 400 million euros (£371 million) for the construction of the facility and its operation over 20 years. The incinerator bottom ash produced by the facility will be transported to a state of the art processing facility, where many of the metals which would have been lost to landfill will be recovered and sent for further processing before resmelting into recycled materials. The remaining cleaned sand, gravels and aggregates are suitable for re-use in certain construction projects throughout Eastern Scotland and off set the carbon generated from quarrying the equivalent volume of raw materials. .

Gadolinium(III) hydroxide. Gadolinium(III) hydroxide is a chemical compound with the formula Gd(OH)3. Its nanoparticles has a potential use for layering various drugs, such as diclofenac, ibuprofen, and naproxen.

Production and properties
Gadolinium(III) hydroxide can be produced in various ways such as the reaction of gadolinium(III) nitrate and sodium hydroxide:
Gd(NO3)3 + NaOH → Gd(OH)3 + NaNO3
If this compound is heated to 307 °C, it decomposes to gadolinium(III) oxide-hydroxide(GdOOH), which in turn decomposes to gadolinium(III) oxide if continually heated.

Uses
Gadolinium(III) hydroxide has no commercial uses. However, gadolinium(III) hydroxide nanoparticles have gained interest as a coating agent for various anti-inflammatory drugs such as diclofenac, ibuprofen, and naproxen due to their property to be non-cytotoxic. The nanoparticles are produced by adding base anion exchange resin to gadolinium(III) nitrate.

Purulia Pumped Storage Power Station. The Purulia Pumped Storage Project is a pumped storage hydroelectric power plant, located at Purulia district of West Bengal, India. The Ajodhya Hills offered suitable terrain for construction of upper and lower reservoirs. The scheme can supply a maximum power of .

Construction 
The project is constructed on Kistobazar nullah which is a tributary of Sobha nullah in Ajodhya Hills. The project was planned to be commissioned in 2002-03, but litigations during tender stage and difficulties in getting clearance for forested land caused delays to the project. Japan International Cooperation Agency (JICA) provided  of loan assistant for the project.

The local villagers protested against the project, as the villagers alleged massive loss of vegetation in the area and hundreds of villagers allegedly lost their livelihoods.

Purpose 
The objective of project is to meet load demand by producing power through the turbines at the peak load time and utilize surplus power available of the system during off peak time by pumping the water to upper reservoir, thus achieving the flatter load demand curve and maintaining the frequency.

It is operated not only to help meet the peak loads but also as a short term operating reserve (STOR), providing a fast response to short-term rapid changes in power demand, both hike and drop, or sudden loss of power generating stations. On 5 April, 2020 when people switched off their lights at 9 PM by request of Prime Minister Narendra Modi for solidarity in fight against COVID-19 pandemic, the West Bengal grid load was expected to dropped by 1 GW. While the national grid load was estimated to drop by 12 - 14 GW, far from the estimate the national grid power demand was dropped 31 GW in a span of 25 minutes. Out of 31,089 MW of power drop 17,543 MW of power was adjusted by hydro power facility across the country, While Purulia pumped storage adjusted about 700 MW of power drop by ramping down its generation to zero, Hydropower facility across the country played vital role for maintaining grid frequency.

Due to the increase in renewable power like solar and wind, the intermittency of power generation is increasing in India. Considering the future prospects another pumped storage projects at Turga (Purulia district, West Bengal) and Nilgiris (Tamil Nadu) are in planning phase.

Capacity 
The installed capacity is 900 MW (4*225 MW).

2-Ethylhexyl glycidyl ether. 2-Ethylhexyl glycidyl ether is a liquid organic molecule with formula C11H22O2 an industrial chemical used to reduce the viscosity of epoxy resins. These are then used in adhesives, sealants, and paints or coatings. It has the CAS Registry Number of 2461-15-6. It has the IUPAC name of 2-(2-ethylhexoxymethyl)oxirane. It also finds use in other polymer based applications.

Synthesis
2-Ethylhexanol and epichlorohydrin are reacted in the presence of a Lewis acid catalyst in a condensation reaction to form a halohydrin. This is followed by a caustic dehydrochlorination, to form 2-ethylhexyl glycidyl ether. The waste products are water and sodium chloride and excess caustic soda. One of the quality control tests would involve measuring the Epoxy value by determination of the epoxy equivalent weight.

Commercial
The material is produced domestically in the United States and is also produced in other parts of the world. Over 13 million kg were exported from China in 2019.

Uses
As an Epoxy modifier it is classed as an epoxy reactive diluent. As well as being used as an epoxy resin diluent, it maybe further reacted to produce cosmetics. It is also used to synthesize other molecules. The use of the diluent does effect mechanical properties and microstructure of epoxy resins.

Safety
The safety of the product is fairly well understood. It is classed as a skin sensitizer.

Deweighting. Deweighting, deweighing or weight reduction, is a chemical treatment that peels the surface of polyester fibers and makes them softer and finer. It also reduces the fiber weight and hence weakens the strength. Additionally, the treatment enhances the absorbency of the treated substrates. Deweighting is an alkaline hydrolysis treatment that affects the surface fibers of the polyester and reduces the decitex or denier of fibers, weight loss of between 10% and 30% is possible during the treatment. Polyester and cotton blends can be treated with an alkali process to make them look and feel like silk.

Process of deweighting 
When Sodium hydroxide (5~10 grams per litre) is applied to polyester in hot conditions, the chemical reaction peels off the surface of the polyester fibers and changes the surface of the finished product, making it softer and finer in texture. During treatment, it is necessary to consider the loss of strength and the degree of softness. Treatment may be carried out by the exhaust method in a dyeing vessel such as an overflow, HT, or winch dyeing machine. The addition of a cationic accelerator and the use of a HT (high temperature) vessel can accelerate the alkalization process. Finally, an anionic surfactant is applied to prevent further deweighting and to aid in the dispersion of the peeled fibers.

Alkali deweighing of polyester 
Alkali deweighing treatment of polyester fiber is a complicated process that includes treatment with caustic at a hot temperature. The hydraulic action peels the surface, resulting in a weakening of the fiber and an increase in its softness and fineness. Hence, care should be taken while treating. The deweighting rate of the fabric can be changed by manipulating the temperature and time.

Alkali deweighting of polyester fiber with imidazole ionic liquid is helpful in accelerating the deweighing action. The processing with imidazole ionic liquid can improve alkali deweighting efficiency and increase alkali agent usage rate while using less alkali agent.

One-bath alkali deweighting and dyeing process 
Deweighting and simultaneously dyeing with disperse dye is also possible, which avoids the two-step process of deweighting and then dyeing in another bath.

Bicomponent 
Alkali deweighting of bicomponent containing polytrimethylene terephthalate/polyamide 6 separates the PTT and nylon components of the yarns, resulting in superfine filaments with a change in fiber diameter and shape.

BornHack. BornHack (a portmanteau of "Bornholm" and "hack") is an annual hacker camp on the Danish island of Funen, near Gelsted. From 2016 to 2018, it was organized on Bornholm.

History 
In 2021, the BornHack electronic badge was based on a perfboard due to the chip shortage. The 2021 camp was also captured in Google Maps' aerial pictures.

In 2022, Thomas Flummer developed a badge based on the RP2040, for which software can be developed in CircuitPython.

During BornHack there is a field specifically designed for loud noise, with a noise barrier made from soil. A Dutch hacker brought an old civil defense siren for testing purposes. Within a few minutes, four separate phone calls were made to the Danish police from houses located a large distance from BornHack.
