Improvised Explosive Devices (IEDs)

IEDs are not manufactured by any fixed standards, therefore their materials of construction, composition of ingredients varies widely. Everything depends upon the availability of resources, knowledge and skill of user.
Explosives composition
 Various ingredients include the various combinations of oxidizer and fuel. For example:

1) Potassium chlorate + Arsenic sulphide + missiles (iron nails, glass pieces , stone chips etc.,) - Throw-down device.
2) Potassium chlorate + sugar initiated by conc., Sulphuric acid - Acid bomb

Improvisation can be made on container, main charge, initiation device and projectiles depending upon the availability, skill, motive and means. For example:

Container; Tiffin carrier, transistor, cement pipe, iron pipe, telephone, Television, toys, cell-phone, computer, scooter, cycle, the articles which are easily available to the anti social elements. ( ref1 ,2&3)
Main charge : High explosives, Low explosives or combinations.
Initiation device: Time device, remote device and impact device, battery operated etc.
Projectile & Missiles: Iron nails, glass pieces, stone ships, ball bearing, generally used in throw down improvised devices.
Factory made ammunition:
In case of factory made ammunition, these are manufactured according to standard specifications. The ammunition bear factory name, batch/ lot no., year of manufacture etc.
Some of the explosive composition commonly used in factory made ammunition are listed below.
Composition B (60% RDX, 40% TNT plus wax)
Cyclotol (60-75 % RDX, 25-40% TNT)
Torpex 2 (42% RDX, 40% TNT, 18% Al)
Composition C4 (91% RDX, 9% plasticisers)
Picratol (TNT + ammonium picrate)
Tritonal (TNT +  aluminium powder)
C1: RDX + Plasticizer
C2:   RDX+TNT +DNT + MNT +NC+Dimethyl Formanide

How to test Blood: Confirmatory Tests in Forensic Practice

Preliminary examination of blood stains do not confirm the presence of blood. It merely indicates that the positive stain might be due to blood.
In order to confirm the identity of blood, there are certain crystal and spectroscopic tests that are regularly employed in the forensic science laboratories.

1. Takayama Test:

Reagent Preparation:

Standard Glucose Solution (100g/100ml) 3 ml
10% Sodium hydroxide (NaOH) 3 ml
Pyridine 3 ml
Distilled Water 7 ml
Reagents should be made fresh daily.

1. Place material to be tested on a microscopic slide and cover with a cover slip.
2. Add a drop of Takayama Reagentand allow to flow under the cover slip.
3. Warm slide gently at 65oC for 10-20 seconds
4. Allow to cool and observe under microscope at 100X magnification.
The appearance of pink needle shaped crystals of pyridine hemochromogen (Pyridine ferroprotoprophyrin) is positive reaction for heme.

2. Teichmann’s Test:

Reagent Preparation:
Potassium Chloride or 0.1 g
Potassium Bro…

How to Sketch a Molecule from Scratch: Part-1

It is often necessary in various scientific disciplines to prepare sketches of molecules for project reports, research papers and teaching assignments, etc. Drawing a sketch also helps in developing the concepts in science, for example, the bonding patter in organic molecules, their valencies, etc. Educators and researchers regularly use sketches in their daily work. With the development of computing computer based sketching has become more  common and more and more people are using computers for everything for drug design, manufacturing and publications of results. Several tools are available for sketching. Here, we will see how small molecules can be drawn using an exciting and free software ‘ACDChem Sketch’ from ACD Labs. Lets begin by drawing a simple molecule ‘Indole’. The pictures below are self explaining.

You can build a larger molecule by adding side chains at the desired positions on the main Indole ring. The method is shown below.

Apart from building simpler molecule like indole…
