(See FIGURE-4) (FIGURE-4) In order to tell how much borneol is formed during reactions‚ both qualitatively and quantitatively‚ infrared spectroscopy and gas chromatography are executed on the products formed from Sodium Borohydride Reduction and Meerwein-Ponndorf-Verley Reduction (MPV). Infrared (IR) spectroscopy shows the relative absorption of specific chemical bonds in a molecule to the induced infrared radioactive energy. Thus from looking at the peaks on IR spectrum‚ possible functional

However‚ these doped materials‚ in general‚ show a small absorption in the visible-light region‚ leading to low activities.[14] New and more efficient visible-light photocatalysts are needed to meet the requirements of future environmental and energy technologies driven by solar energy.

protein is important in determining the tertiary structure of the protein. The ovalbumin is the experiment was purified from egg white using centrifugation and ammonium sulphate precipitation and then the thiol groups identified using DTNB and spectroscopy. The ovalbumin was found to have one thiol group; from this we were also to infer that DNTB alkylates thiolgroups; whereas SDS keeps proteins denatured. Introduction A thiol group is a functional group containing a sulphur atom bonded to a

For the treatment of cancer most of the drugs currently available but they have limited therapeutic potential because they are very toxic‚ expensive‚ highly inappropriate action in treating cancer‚ or having so many side effects like granulocytopenia‚ agranulocytosis‚ lymphocytopenia‚ alopecia‚ carcinogenicity or secondary cancer especially leukaemias and hyperuricaemia etc. Curcumin is one such natural herbal medicine‚ derived from the extraction of dried rhizome of turmeric or Curcumin longa‚

[Co(NH3)5(NO2-O)]Cl2 (red/ salmon-pink crystal) The complexes [Co(NH3)5(NO2-N)]Cl2 and [Co(NH3)5(NO2-O)]Cl2 can be distinguished by using IR-spectroscopy. The hypothesis was these complexes can be differ by the color of there crystals‚ e.g. [Co(NH3)5(NO2-N)]Cl2 (yellow or orange-brown) and [Co(NH3)5(NO2-O)]Cl2 (red/ salmon-pink crystal). For the O-bonded ligand‚ characteristic absorption bands at 1065 and 1470 cm-1 are observed‚ while for the N-bonded ligand‚ the corresponding vibration wave number are 1310 and

sufficiently free from protein contamination where CT‐DNA solution gave a ratio of UV absorption at 260/280 nm equal to 1.92. The stock solution was stored at 4 0C and used within for 4 days. The investigated complexes were dissolved in DMF solvent. Electronic spectra experiments were performed by keeping investigated complexes concentrations constant while changing the CT-DNA concentration in the interaction medium. The absorption due to free CT-DNA was eliminated by adding a proper amount of CT-DNA to both

Unit _ - Control of Air Pollution FABRIC FILTER – It consists of a tabular bag which is closed at the upper end and has a happer attached at the lower end to collect particles when they are dislodged from the fabric. Many such bags are hanged in a bag house. The filter bags are cleaned occasionally by a mechanical shaker for efficient filtration. It has high efficiency and can filter 0.5 µm size particles.

SEWAGE TREATMENT Sewage is a mixture of domestic and industrial wastes. It is more than 99% water‚ but the remainder contains some ions‚ suspended solids and harmful bacteria that must be removed before the water is released into the sea. The treatment of wastewater is divided into three phases: pretreatment‚ primary treatment and secondary treatment. Pretreatment Large solids (i.e. those with a diameter of more than 2cm) and grit (heavy solids) are removed by screening. These are disposed of in

After purification and NMR and UV-visible spectra was taking for the original porphyrin synthesized and the silver porphyrin. From this data obtained we will talk about silver’s effect on porphyrin. Theory Porphyrin is important to study because it plays keys roles in biological process; they are responsible for giving plants and blood their colors green and red respectively. Porphyrins have the iron chelate
