A simple, highly efficient, inexpensive, and environmentally friendly process could provide a viable pathway for the sustainable recycling of depleted lithium-ion batteries (LIBs): No chemicals beyond citric acid need to be added to leach out and separate over 99 % of the lithium, nickel, cobalt, and manganese metals contained in NCM batteries. The resulting recycled material can be directly converted into NCM electrodes, reports a research team.

Делюсь, как делаю это сейчас. Читать далее Read more ›

Любому руководителю, у которого к команде есть эксперт, предлагаю сделать татуировку: эксперт всегда должен быть доступен. Под экспертом я понимаю человека со сверхкомпетенциями – сеньора, суперархитектора, мегаспеца по выруливанию сложных ситуаций с клиентами.Никогда не загружайте эксперта на фуллтайм, не давайте длинных неделимых задач (которые нельзя в любой момент отложить), не отдавайте в длинные проекты на линейных ролях (разработчик, аналитик, консультант). Любая загрузка, которая делает эксперта нед Read more ›

Наш загрузчик оказался слишком медленным. Требование было чётким: загружаться менее чем за 500 миллисекунд. Показатели оставались не менее чёткими: 720 миллисекунд. Мы отставали от нужного значения на 44%.Это требование не было «мягким». Загрузчик должен был работать в промышленном контроллере, обязанном реагировать вскоре после включения питания. Каждая секунда времени загрузки — это потерянная продуктивность. В спецификации к изделию был указан максимум в 500 мс. Мы обязаны были их обеспечить.Задача загру Read more ›

Two dangerous viruses are back in the spotlight, reminding health officials how quickly infectious diseases can become serious threats. Hantavirus, often linked to rodents, can cause severe heart and lung complications and has no specific treatment or vaccine, while certain strains can even spread between people. Ebola remains one of the world's most feared diseases, with some outbreaks killing up to half of those infected, although vaccines and antivirals have... Read more ›

Scientists discovered that Heliconius butterflies have evolved an extraordinary lifespan, living several times longer than closely related species. Even more surprising, some show little sign of physical decline as they age. Their unusual pollen-feeding lifestyle may play a role, but the research suggests deeper evolutionary changes are also helping them stay healthy for longer. Read more ›

Scientists found that niacin may help revive immune cells that tumors shut down, allowing them to attack cancer more effectively. Early results have been promising, with patients showing significantly better progression-free survival than expected. Read more ›

A colossal ancient collision may have left some of the Moon’s deepest secrets surprisingly close to future Artemis landing sites. By recreating the impact that formed the giant South Pole-Aitken basin—the Moon’s largest and oldest crater—scientists found that a low-angle strike from a large, iron-cored object blasted material from deep inside the Moon, including mantle rocks.

Trees planted to protect farmland from wind may not be the biodiversity boost many assume. In Japan’s wetland farming landscapes, shelterbelts benefited some birds but sharply reduced grassland and wetland species that need open space. Researchers found grassland bird abundance dropped by more than 70% near shelterbelts. Read more ›
