This item is printed on demand - it takes 3-4 days longer - Neuware -Die Proben wurden in den Bergen von Malakand, KPK, gesammelt und zu kleineren Partikeln zermahlen. Die Proben wurden im Soxhlet-Apparat mit verschiedenen Lösungsmitteln extrahiert, um die löslichen Extraktions- und Wachssubstanzen zu entfernen. Die Rohzellulose wurde im Autoklaven mit alkalischen Substanzen behandelt, um die Bindungen aufzubrechen. Die meisten polaren Substanzen wurden durch EDTA und Wasserstoffperoxid entfernt. Außerdem wurden die Proben mit Essigsäure und Salpetersäure gereinigt. Die Cellulose wurde mit doppelt destilliertem Wasser neutralisiert, bis ein neutraler pH-Wert erreicht war. Die gereinigte Cellulose wurde mit verschiedenen Analysetechniken charakterisiert, z. B. Röntgendiffraktion (XRD) zeigt eine hohe Kristallinität von 73 %. FTIR zeigt die Entfernung verschiedener funktioneller Gruppen von der Oberfläche. Die TGA zeigt, dass die aus verschiedenen Holzquellen gewonnene Cellulose bei 100 C Wasser verliert, bei 250 C löslich wird und bei 350 C Lignin und Hemicellulose verliert. Die REM-Untersuchung zeigt, dass die Oberflächenmorphologie und die Form der Poren deutlich sichtbar sind. Die isolierte Cellulose weist eine hohe Kristallinität, thermische Stabilität und gute mechanische Eigenschaften auf. 100 pp. Deutsch.…

Information regarding the right of withdrawal
Statutory right to withdraw
You have the right to withdraw from this contract within 14 days without giving any reason.

Effects of withdrawal
If you withdraw from this contract, we will reimburse to you all payments received from you, including the costs of delivery (except for the supplementary costs arising if you chose a type of delivery other than the least expensive type of standard delivery offered by us).
We may make a deduction from the reimbursement for loss in value of any goods supplied, if the loss is the result of unnecessary handling by you.
We will make the reimbursement without undue delay, and not later than 14 days after the day on which we are informed about your decision to withdraw from this contract.
We will make the reimbursement using the same means of payment as you used for the initial transaction, unless you have expressly agreed otherwise; in any event, you will not incur any fees as a result of such reimbursement.

The right of withdrawal does not apply to:
- The delivery of newspapers, journals or magazines with the exception of subscription contracts; and
