🔍 نانومواد: دنیای مواد زیر 100 نانومتر

از آنجایی که بیشترین تغییرات در ویژگی‌ها و رفتار ماده در اندازه‌های زیر 100 نانومتر ظاهر می‌شود، به این مواد نانوماده می‌گوییم. ✨

اما این تعریف اولیه و ساده است! 🤔 در دنیای سه‌بعدی، سه مولفه برای اندازه داریم: طول، عرض و ارتفاع. وقتی می‌گوییم اندازه زیر 100 نانومتر، باید دقیقاً مشخص کنیم که کدام یک از این سه بعد منظور است. 📏

💠 پس، تعریف دقیق‌تر این‌طور می‌شود: به مادۀ که حداقل در یکی از ابعاد (طول، عرض یا ارتفاع) اندازه‌ای کوچکتر یا مساوی 100 نانومتر داشته باشد، نانوماده می‌گوییم. 🔬

👁‍🗨 حالا که توضیح دادیم، تقسیم‌بندی نانومواد رو براساس شکل و ساختار هندسی‌شان بررسی می‌کنیم. همانطور که در هندسه با حجم (۳ بعدی)، سطح (۲ بعدی)، خط (یک بعدی) و نقطه (صفر بعدی) سر و کار داریم، می‌توانیم این تقسیم‌بندی رو برای نانومواد هم به کار ببریم.

📌 تقسیم‌بندی نانومواد براساس ابعاد آزادشان:

1️⃣ صفر بعدی (0D)
2️⃣ یک بعدی (1D)
3️⃣ دو بعدی (2D)
4️⃣ سه بعدی (3D)

Newly uncovered hack campaign in Telegram

The campaign, which security firm Check Point has named Rampant Kitten, comprises two main components, one for Windows and the other for Android. Rampant Kitten’s objective is to steal Telegram messages, passwords, and two-factor authentication codes sent by SMS and then also take screenshots and record sounds within earshot of an infected phone, the researchers said in a post published on Friday.

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.
