Флешки большого объёма сделают на искусственном пигменте

Миниатюрные устройства для записи и хранения информации, датчики и сенсоры на «молекулярных магнитах» поможет изготовить новое химическое соединение. Российские учёные создали его на основе редкоземельного металла диспрозия и синтетического аналога кровяного пигмента — порфирина.

Кристаллы этого магнитно-активного вещества способны приобретать и сохранять намагниченность после отключения магнитного поля. При этом его функциональные единицы в миллиарды раз меньше магнитов, используемых в современной технике.

Теперь специалисты Федерального исследовательского центра проблем химической физики и медицинской химии РАН собираются заменить диспрозий атомами других металлов, чтобы намагниченность можно было менять не только полем, но и, например, температурой.

What Is Bitcoin?

Bitcoin is a decentralized digital currency that you can buy, sell and exchange directly, without an intermediary like a bank. Bitcoin’s creator, Satoshi Nakamoto, originally described the need for “an electronic payment system based on cryptographic proof instead of trust.” Each and every Bitcoin transaction that’s ever been made exists on a public ledger accessible to everyone, making transactions hard to reverse and difficult to fake. That’s by design: Core to their decentralized nature, Bitcoins aren’t backed by the government or any issuing institution, and there’s nothing to guarantee their value besides the proof baked in the heart of the system. “The reason why it’s worth money is simply because we, as people, decided it has value—same as gold,” says Anton Mozgovoy, co-founder & CEO of digital financial service company Holyheld.

With Telegram, you can send messages, photos, videos and files of any type (doc, zip, mp3, etc), as well as create groups for up to 200,000 people or channels for broadcasting to unlimited audiences.
