Conducting polymers have extended p-orbital system, through which electrons can be moved from one end to another and of polymer. Also, when a polymer is doped, there are changes in it due to resonance the charge can drift through the chain, and generating the conductivity.

Projet de création de produit pour Kérastase en cours de "Innovation" dispensé par Jean Saucet.
L'objectif était de créer un shampoing suffisamment innovant pour dynamiser l'Offre de Kérastase et toucher une nouvelle cible.
Nous avons pris le parti de séduire la cible masculine par la nano technologie.
J'étais en charge, outre ma participation à la détermination du concept, d'une partie du mix produit, du packaging et du mix communication.
Un remerciement tout particulier à Richard Tatetessian mon ami infographiste pour cette superbe modélisation de packaging.
L’innovation dans les petites et moyennes entreprises (PME) au CamerounUniversité de Dschang
M. Ndzana Eloundou Martin Jaurès a soutenu une thèse de Doctorat/Phd en Sciences Économiques ce 15 juin 2016 à l'Université de Dschang. Le jury présidé par le Prof. Désiré Avom lui a décerné la mention honorable.
Global anti-agers were worth US$25 billion with a value sales growth of 4% in 2013. In this presentation, we can see the performance of premium and mass anti-agers at both a global and Asia Pacific context. Looking at global anti-agers trends, some focus areas of this presentation are the adoption of anti-agers among younger consumers; the development of anti-aging elements beyond skin care products to other sectors such as hair care; and rising presence of anti-agers for men.
This presentation gives a brief information about hair structure, biochemistry, pigments, the cause of hair graying and the herbs which are helpful to get rid of hair graying.

The Science of Stunning Hair Color Toledo OHs Leading Specialists ExplainSelect Salon Studios
The science of hair color is not easy to understand. However, hair color specialists in Toledo, OH have made it simple and straightforward. According to them, the science of hair color is based on the relationship between natural and artificial pigments with the hair structure. Here are some points summarizing what the top specialists in Toledo say:
Laser Hair Removal
Also known as light based hair removal and laser hair reduction
Laser hair removal is a convenient, noninvasive method for permanently reducing or removing unwanted facial or body hair. It leaves the skin looking smoother and silkier than waxing, electrolysis or razors and is a gentle technique that can treat larger areas effectively with minimal discomfort and with no downtime. Today, laser hair removal is one of the most common aesthetic procedures performed in the United States.
It is a research paper which talks about Mimicking the melanin production to help in coloring the human hair. The paper has been published in ACS journal(2017).
EXTRACTION OF KERATIN FROM HUMAN HAIR WASTE.pptx25DeepakKushwaha
extraction of keratin from human hair
in this ppt you are going to learn about extraction of keratin from the human hair waste with a very simple method and the method is economic
1. Analysis of Synthetic Compounds
on Hair by Using FTIR for
Forensics Purpose
Honour Seminar Presentation (SCS 4901)
Islamic Science University of Malaysia (USIM)
2. Introduction
Hair in Forensic
Role of hair in investigation
- Trace elements
- Secondary transfer
Role of FTIR in investigation
- Can provide rapid and specific chemical
composition
- Small quantity of sample needed (suitable for
limited quantity of trace elements)
3. Introduction
The white color on hair commonly gives an old appearance to people
and they tend to do hair treatment in order to look fresh and versatile.
Moreover, not only women, but also men change their hair color to
look attractive and get new image in represent self-confidence and
social success.
There are abundance of chemical compounds used in the hair treatment that
will affect the molecular structure of the hair fiber. It can be detected by using
Fourier Transform Infrared Spectroscopy (FTIR).
4. Hair Morphological Composition
- Outermost layer of hair fiber
The Cuticle
- Important in chemical resistance, protection and stability of hair
- Shows the age of hair
The Cortex
- The larger portion of hair by mass and volume
- Important in mechanical aspect and properties of hair fiber
- Contain melanin
- Inner part with diameter 5-10µm
The Medulla
- Important in thermal insulation and resistance to alkali
- Contains pigment granules (pheomelanins and eumelanins)
5. Hair Chemical Composition
Elements Pigments
• C, H, O, N and S are main • Determine the color
elements • Eumelanin give light color
• Sweet deposits, environment • Pheomelanin give dark color
and metabolic irregularities
are primary root of trace
elements
Lipids Proteins
• Free lipids • Main composition in hair
• Important for the condition • Depend on the individuals diet
known as oily hair • 20 amino acid presents in
protein
6. Treated and Untreated Hair
There are five types of chemical treatments
Oxidation
Dye Bleaching Waxing Straightening with Chlorine
7. Cont.
Dye – permanents, semi-permanents and temporary
(oxidative species containing phenylenediamines, aminophenols,
dihydroxybenzenes, and nitro compound)
Bleaching – alkaline medium, hydrogen peroxide and ammonium
Waxing – total reconstruction with ammonia and ammonium hydroxide
Hair straightening – strong base such as such as sodium hydroxide
Oxidation with chlorine - There are 2 oxidising species whether Cl2 and
HOCl that will cleave peptide bond and disulphide bond depending in the pH
of water
8. The Principle of Methodology
• Obtain hair sample from the donor
• Cut into certain length
1
• Flattened with roller knife
• Transferred to bottom KBr salt plate
2
• Second KBr plate placed on the top
• Run with FTIR and collect the reading of spectrum

9. Fourier Transform Infrared
Spectroscopy (FTIR)
- High resolution
- High scan rate
Improved infrared Has movable and
spectra stationary mirror. - Respond only to
modulated light

12. Conclusion
Infrared spectroscopy is an important technique for aiding forensic
scientists in their investigations. Individual hair fibers can easily be
analyzed, and differences due to chemical damage, natural
weathering, and cosmetic treatments are readily apparent.
It is also provide an information about functional group that help
the researcher or investigator to predict the chemical compound.
