Вторую жизнь лигнину пытаются дать ученые Лавёровского центра
Особое применение компоненту древесины — лигнину — ищут архангельские ученые Лавёровского центра. Они провели исследования его электрофизических свойств. В будущем этот материал может стать перспективным для создания электрических конденсаторов.

They may value access to news and communication with their loved ones over making sure that all of their communications are encrypted in such a manner that they are indecipherable to Telegram, its employees, or governments with court orders.
