حتماً ✅ فقط برای اینکه تصویر دقیق و علمی بسازم، لطفاً تأیید کنید منظورت این حالت است: می‌خواهی **یک تصویر شماتیک (schematic diagram)** از **فرآیند اصلاح سطح قلیایی (alkaline treatment)** الیاف جوت با **سدیم هیدروکسید (NaOH)** را نشان بدهم، یعنی: * الیاف جوت شامل سلولز (با گروه‌های –OH) هستند. * تیمار با NaOH باعث حذف مواد غیرسلولزی (مثل لیگنین و همی‌سلولز) و تبدیل گروه‌های –OH به –ONa یا بازآرایی ساختار می‌شود. * در تصویر نشان داده شود که قبل و بعد از اصلاح چه تغییر شیمیایی رخ می‌دهد (مثلاً قبل: Cell–OH ؛ بعد از تیمار: Cell–O⁻ Na⁺). آیا همین نوع تصویر مدنظر توست (شماتیک واکنش سطحی قبل و بعد از تیمار قلیایی)، یا می‌خواهی مدل مولکولی دقیق‌تر (با حلقه‌های گلوکز سلولز) بسازم؟ وقتی تأیید کردی، تصویر را می‌سازم.
