Bloodstains are often encountered at scenes of violent crime and have significant forensic value for criminal investigations. Blood is one of the most commonly encountered types of biological evidence and is the most commonly observed fingerprint contaminant. Presumptive tests are used to test blood stain and blood stained fingerprints are targeted with chemical enhancement methods, such as aci...

The effect of acid-alkaline treatment of lignocellulosic material (wild carob forest wastes) on Ethyl violet adsorption was investigated. It was found that surface chemistry plays an important role in Ethyl Violet (EV) adsorption. HCl treatment produces more active acidic surface groups such as carboxylic and lactone, resulting in an increase in the adsorption of EV dye. The adsorp...

A unique combination of adsorption and electrochemical regeneration with a proprietary adsorbent material called Nyex 100 was introduced at the University of Manchester for waste water treatment applications. Nyex 100 is based on graphite intercalation compound. It is non porous and electrically conducing adsorbent material. This material exhibited very small BET surface area i.e. 2.75 mg, in c...

Copper nanowires have the potential to reach and even exceed the indium tin oxide performances as flexible transparent conductive electrodes. However, for a large-scale production, they need to be fabricated in a high-speed, low-cost way, without degrading the flexible substrate. One of the major bottlenecks resides in the post-treatment used to remove organic residues from the surface of the n...

fertilizer plant waste carbon slurry has been investigated after some processing as an adsorbent for the removal of dyes and phenols using columns. the results show that the carbonaceous adsorbent prepared from carbon slurry being porous and having appreciable surface area (380 m2/g) can remove dyes both cationic (meldola blue, methylene blue, chrysoidine g, crystal violet) as well as anionic (...

In this study, 12 varieties of statice (Limonium sinuatum L.) were collected from famous flower growing areas (Van Thanh, Thai Phien, Da Thien, Ha Dong and Trai Mat) in Lam Dong. Young foliage flowering cultivars after 45 days planting at the experimental site was for DNA extraction genetic correlation analysis using RAPD with 13 random primers. Results showed that out 145 bands, there 133 poly...

Photolysis and photocatalysis of Lauth's violet using nano-titanium dioxide at various aqueous buffer and non-buffer pHs. The effects of some various operating parameters such as initial dye concentration, medium pH, illumination time and catalyst amount have been investigated in a photoreactor equipped with high pressure mercury lamp. Spectrophotometric methods supported that the dye is al...

A series of monoazo disperse dyes based on naphthalimide was synthesized using N-alkylcarboxylic acid-1,8-naphthalimide as diazo component and N,N-diethylaniline derivatives as a coupling components. 4-amino-N-ethanoic (propanoic) acid-1,8-naphthalimide was synthesized from 4-nitro-1,8-naphthalic anhydride by imidation and subsequent reduction reactions. These compounds were diazotized and furt...
