Hydrogen cyanide

• These restrictions were expected to further disrupt the hydrogen cyanide market by limiting imports or exports from the region affected by the conflict.
• Based on product, the hydrogen cyanide liquid segment held the highest market share in 2022, accounting for around three-fifths of the global hydrogen cyanide market revenue and is expected to maintain its lead position throughout the forecast period.
• However, the hydrogen cyanide gas segment is projected to manifest the highest CAGR of 2.2% from 2023 to 2032.
• In addition, the growing adoption of hydrogen cyanide in mining applications and the expanding chemical manufacturing sector contribute to the market growth in the region.

The science of smell

• For humans, too, being able to smell is not just for the enjoyment of pleasant odours.
• When we smell a scent, gas molecules enter our nose and stimulate specialised nerve cells called olfactory sensory neurons.
• When this is the case, more molecules enter the gaseous state and the smell is more intense.

What makes things smell good though?

• Fish and decaying animal cells, for example, release chemicals called amines, which don’t smell appealing.
• Chemists have been able to identify the specific chemical smells released by substances we encounter in everyday life.

Smells different

• However, some perfumes also contain unusual ingredients that don’t smell nice on their own.
• 5 perfume – the iconic 100-year-old favourite – contains civet as one of its base chemical notes.
• It is traditionally extracted from the anal glands of civet cats but Chanel has used a synthetic form of civet since 1998.

Tips for choosing and using perfumes

• This will help to give molecules more energy and increase the number of molecules entering the gaseous state.
• Specific perfumes will not smell the same on different people’s skin because the chemicals in them can be affected by the skin’s type and condition (dry or oily, acidic or base) and even their diet.
• That’s also why it’s better to moisturise skin before spraying perfume, so perfume chemicals stay on the skin for longer.
• To keep perfumes lasting longer in the bottle, keep them in the fridge or cool dark place and tightly sealed to prevent your expensive, heat-sensitive scent evaporating into thin air.

• "Since the Hayabusa2 spacecraft collected two samples directly from asteroid Ryugu and delivered them to Earth in sealed capsules, contamination can be ruled out."
• The team hypothesizes that the difference in concentrations in the two samples, collected from different locations on Ryugu, is likely due to the exposure to the extreme environments of space.
• While these were not detected in the Ryugu samples, they are known to be present in cometary ice—and Ryugu could have originated as a comet or another parent body which had been present in low temperature environments.
• "The discovery of uracil in the samples from Ryugu lends strength to current theories regarding the source of nucleobases in the early Earth," Oba concludes.

• Draslovka Holding a.s. (Draslovka or the Company), a Czech-based, global leader in cyanide-based chemical specialties and agricultural chemicals including next generation fumigants and biocides, has temporarily reduced production of sodium cyanide (NaCN) to a minimum level at its facility in Koln, Czech Republic.
• Draslovka Mining Solutions plant in Memphis, Americas largest sodium cyanide production facility, is unaffected by this decision, and will be fully utilized to ensure the ongoing seamless supply to Draslovkas customers.
• Draslovka recognizes the mining industrys critical need for a reliable supply of sodium cyanide and we will continue working diligently to support our customers operations.
• Draslovka Mining Solutions, a fully owne subsidiary of Draslovka Holding, is the world leader in solid sodium cyanide (NaCN) production headquartered in the United States.
