    Services offered by the Center

 

 
  The services the research center offers to encourage scientific research in the College of Sciences may be summed up in the following:

 

1.     Providing financial support necessary for research project registered in the center to purchase equipment and spare parts and raw materials and consumer-goods

2.     Assisting researchers who have research papers registered in the center (or who do research in the College) with conducting experiments and sample analysis, representing them diagrammatically, and preparing rsearch reports in their final stages for publication

3.     Assisting researchers with various sample analyses in case the desired equipment for such analysis  is not available in the University

4.     Informing College faculty of scientific conferences and symposia in order to participate in them

5.     Co-operating with local media and "The University's Message" to highlight the College's scientific and academic activities and introducing those taking part

6.     Discussing and studying research papers and projects presented by facultyto the Center and delineating future plans to match the progress and growing activities of the Center

7.     making available the financial expenses required for urgent consumer-goods and spare parts unavailable in the University

8.     Repairing and installing electronic equipment for the Center and on its expenses

9.     Following up the progress of research projects registered in the Center and supervising research progressin Departments and solving problems that might hinder research technically or financially

10.       Supervising equipping and functioning the College's central laboratory and providing manpower needed to function  the Central Laboratory's Units and Factories

The Central Laboratory

Introduction

 

      

The foundation of a central Laboratory for the Departments of the College of Sciences to be supervised by the Management of the Research Center was initiated by the urgency to decrease the expenses of equipment needed for conducting research in the College and to make oppoprtunities available to faculty and postgraduate students to do their own research.  In addition, such a Lab would provide expensive modern scientific equipment which individual Department cannot otherwise afford providing its students with.

          The Central Lab serves faculty and postgraduates and offers its scientific services to other institutes both inside and outside the University. The Central Lab houses the following units:

          A. The Unit of Electronic Microscopes, which includes:

1. Trenchant Electronic Microscope (TEM): This unit studies the minute cellular structures of biological samples (tissues and microorganisms.  The Unit has three laboratories for sample preparation:

·        The lab of preparing glass knives

·        The Laboratory of preparing semi-minute cutters

·        The Laboratory of minute equipment

2. Scanning Electronic Microscope (SEM): It isd used to study the outer surface of various types of samples.

 

B. X-Ray Unit: this includes:

1. X-Ray Single Crystal Diffractometer: This analyses chemical compounds in accordance with their chemical components through X-Ray Scanning and also deals with Single Crystal Diffractometers.

 

1.     X-Ray Powder Diffractometer: This analyses chemical compounds in accordance with their chemical components through X-Ray Scanning and also deals with Single Powder Diffractometers.

 

C. Element Analysis Unit (CHN):  This is an apparatus that analyses Carbon, Nitrogen, and Hydrogen and gives the percentage of of these three elements in small and racemose organic and organometallic compounds and polymers.

 

D. The Radiating Unit

  This uses the Radiating Cobalt-60 model (gamma Cell 220): It radiates samples with various biological and non-biological gamma rays.  This Unit is equipped with all internationl standards for safety against the hazards of radioactivity. The samples to be radiactivated are placed in the active part in the shape of a cylinder 20.5 cm long and with diameter of 15.5 cm.  The most important use of the Cell is the study of the effect of gamma ray on various elements in physics research and in Radioactive chemistry, radioactive biology and medicine, Pharmacy, agriculture and and research areas.

 

E. Polymers Unit:  This includes:

1. Chromotography Apparatus GPC 150

2. Differrential Scanning Calorimeter

3. Simultaneous Thermal Analysis

4. Plastics-formation Apparatus: It combines plastics and shapes them  as little rods or chips.

5. Solidity Gauge

6. Exertion Gauge

7. Elasticity Gauge

8. Viscidity Gauge

9. Collision Gauge

 F. Atomic Absorption Unit: This analyzes the percentages of  Carbon, Nitrogen and Hydrogen elements in samples. This is a newly installed apparatus.
