🍃 سنتز سبز نانوذرات؛ پیوند علم و طبیعت برای آیندهای پایدار 🌱
🌍 سنتز سبز نانوذرات یکی از نوآوریهای خلاقانه و تحولساز در فناوری نانو است که به کمک آن میتوان نانوذرات را با استفاده از منابع طبیعی تولید کرد. این فرآیند، برخلاف روشهای شیمیایی سنتی، از مواد گیاهی، جلبکها، باکتریها و حتی قارچها بهره میگیرد تا هم اقتصادیتر باشد و هم اثرات زیستمحیطی را به حداقل برساند.

Two days after Russia invaded Ukraine, an account on the Telegram messaging platform posing as President Volodymyr Zelenskiy urged his armed forces to surrender. Meanwhile, a completely redesigned attachment menu appears when sending multiple photos or vides. Users can tap "X selected" (X being the number of items) at the top of the panel to preview how the album will look in the chat when it's sent, as well as rearrange or remove selected media. "Your messages about the movement of the enemy through the official chatbot … bring new trophies every day," the government agency tweeted. The news also helped traders look past another report showing decades-high inflation and shake off some of the volatility from recent sessions. The Bureau of Labor Statistics' February Consumer Price Index (CPI) this week showed another surge in prices even before Russia escalated its attacks in Ukraine. The headline CPI — soaring 7.9% over last year — underscored the sticky inflationary pressures reverberating across the U.S. economy, with everything from groceries to rents and airline fares getting more expensive for everyday consumers. But Telegram says people want to keep their chat history when they get a new phone, and they like having a data backup that will sync their chats across multiple devices. And that is why they let people choose whether they want their messages to be encrypted or not. When not turned on, though, chats are stored on Telegram's services, which are scattered throughout the world. But it has "disclosed 0 bytes of user data to third parties, including governments," Telegram states on its website.
