#polymer — Public Fediverse posts

Recent #numismatic #news has been dominated by the European Central Bank's survey on proposed new euro #Banknote designs. But they aren't the only ones looking to update their notes. The government of #India has authorised the Reserve Bank of India (RBI) to print an initial batch of 2 billion #polymer #banknotes for field trials, the government informed Parliament on Monday.
The RBI has recently floated a tender to procure material for polymer banknotes, reviving a proposal that has been under consideration for nearly two decades.

Hey, can I get a #chemist on the line? Maybe one with #cosmetic or #polymer knowledge?

So, I have psoriatic arthritis, and a manifestation is a degradation of my nails. And I was looking into a product, which is advertised as "beneficial" to one's nails, which is not a thing associated with manicure products.

It is a #uv cured gel, but rubberized in some way.

Here's the thing, all of these "gel" or uv cured products appear to be #resin.

Am I wrong in assuming that both long term exposure to resin and UV is incredibly dangerous? When I've done resin work, I've been fully masked and gloved and all of the safety sheets say to avoid skin contact. I stopped working with it because of safety and environmental concerns.

How is nail resin any more safe?

Топ нейросетей для анализа данных: BotHub, Julius AI, Microsoft Power BI

Помните те времена, когда мы сидели в три часа ночи, пытаясь свести VLOOKUP-ами три кривых CSV-файла, выгруженных из разных CRM, а питоновский скрипт падал из-за одной запятой не в той кодировке? Кажется, это было в прошлой жизни... На дворе апрель 2026 года. Нейросетевой анализ данных – это уже не игрушка для гиков и не R&D-эксперимент с непредсказуемым бюджетом. Это суровая, ежедневная необходимость. Если вы сегодня не используете ИИ для очистки, обогащения и анализа датасетов, вы всё равно что копаете котлован чайной ложкой, пока соседи работают экскаватором. По данным исследований Стокгольмского института окружающей среды, современные LLM достигают 85–90% точности по сравнению с ручной разметкой и анализом даже в таких субъективных вещах, как оценка политических и климатических документов. А в жесткой математике и структурированных таблицах этот процент стремится к абсолютным 100%. В этой статье я собрал ультимативный топ-9 платформ , сервисов и подходов, которые перевернут ваш воркфлоу. От уютных табличек в Google Sheets до суровых кластеров для машинного обучения. Мы разберем, какие инструменты реально работают на проде, и поймем, как стать настоящим архитектором смыслов. Пристегните скафандры, мы погружаемся. И начинаем с абсолютного геймчейнджера.

#Neuralnetwork finds an #enzyme that can break down #polyurethane
A completely new enzyme that researchers developed to break down polyurethane, the #polymer commonly used to make #foam cushioning, among other things. The new enzyme is compatible with an industrial-style recycling process that breaks the polymer down into its basic building blocks, which can be used to form fresh polyurethane.

Researchers have created a #polymer “Chinese lantern” that can snap into more than a dozen curved, three-dimensional shapes by compressing or twisting the original structure. This rapid shape-shifting behavior can be controlled remotely using a magnetic field, allowing the structure to be used for a variety of applications.
