يعد الميتانول و الإيتانول من أكثر المحلات شيوعاً، و بما أن درجة غليانها أقل من مئة
درجة مئوية فإنها تتطاير بشكل سريع. و على سبيل المثال، يستعمل الميتانول في تصنيع
الأصبغة و العقاقير و العطور.. و هو شديد السمية، لذلك من الضروري تطوير محسات لكشفه.

ما غاز الأمونيا فهو من ملوثات الهواء و له مصادر كثيرة مثل صناعة الأسمدة و أنظمة
التبريد.. و من هنا أهمية كشفه.
A chemical sensor was prepared by deposition of polypyrrole films by
chemical polymerization of pyrrole at room temperature, using hexahydrate
ferric chloride as oxidant, on a ceramic substrate placed on the bottom of the
beaker (in-situ polymeriz
ation). On the substrate two interdigitated metallic
electrodes were priory deposited by screen printing, to reduce film resistance.
These films were characterized by different methods namely FTIR, UV-Vis,
XRD.
The ideal goal of periodontal instrumentation is to effectively remove plaque
and calculus without causing root surface damage and various instruments have been designed to achieve
this goal. Root planing aim to create a root surface which is biolo
gically acceptable to surrounding soft
tissues and increase root surface roughness.
Aim of study: To evaluate the increasing of root surface roughness produced by hand curettes and
piezoelectric ultrasonic instrument with different power settings .
Residual Calcium Hydroxide dressing on the root canal is considered
one of the reasons of endodontic treatment failure. So ,the removal of
this dressing completely before filling is required. The aim of the study
was to evaluate the efficiencies o
f passive ultrasonic irrigation And
increasing the instrumentation of the medicated canal to the file one
size larger than MAF in removal of Calcium Hydroxide dressing.
During this study, various types of silicon oxide were prepared
as aerogel and xerogel using multiple precursors and different
drying technics. Some of these samples were prepared from
Sodium silicate (waterglass) Na2SiO3 as a precursor which is a
cheap material, while others were prepared using tetraethoxysilane
(TEOS).
