Molar conductances of Bu4NBr, NaBPh4 and NaBr have been measured in acetonitrile(1) + water(2) mixtures containing 0, 20, 40, 60 and 80 mass% acetonitrile at temperatures ranging from 288.15K to 318.15K at an interval of 5K. The conductance data have been analyzed by Shedlovsky method to obtain Ʌ˳ and KA values of the electrolytes. The ionic contributions to the limiting molar conductance have been estimated using tetrabutyl ammonium tetraphenyl borate (Bu4NBPh4) as the “reference electrolyte”. Thermodynamic quantities for the ion-association process have been derived along with Walden product. All these electrolytes are highly associated in the acetonitrile rich region of the solvent system within the studied temperature ranges. It has been found that solvated radii (ri) of Bu4N+ and Ph4B-decreases with increasing acetonitrile percentage while that of Na+ and Br- show an increase with acetonitrile concentration. Specific interactions of the ions with the solvent molecules have been found to exhibit a profound influence on their mobilities besides the effect of viscosity and permittivity of the media.

 A novel route was developed to recover alumina from red mud by sintering-leaching process using carbonates of alkaline earth metal and sodium carbonate. The chemical composition of red mud is 16.07% Al2O3, 53.75% Fe2O3, 8.25% SiO2, 3.83% Na2O, 4.24% TiO2, 1.48% CaO, 0.148% V2O5, 0.157% MnO, 0.020% MgO, 0.085% Ga2O3, 0.007% ZnO, 0.099% K2O and 11.83% LOI. In this process, the red mud was sintered with carbonates of alkaline earth metal (i.e., BaCO3) and sodium carbonate (Na2CO3) in different mass ratios at 900-1100 oC. The sinter product was leached with suitable concentration of caustic at 105 oC for 1 hr. The minerals and alumina phases present in red mud like gibbsite, gibbsite co-existing with boehmite, alumino-goethite, boehmite and sodalite are converted to soluble sodium meta-aluminate, di-barium silicate, barium ferrite and barium titanate during sintering-leaching process. The maximum alumina extraction was achieved by this novel sintering-leaching process is 99.14 %, 95.57% and 99.50% at a sintering temperature of 900oC, 1000oC and 1100oC, respectively. The formation of barium titanate and barium ferrite was confirmed by x-ray diffractometer (XRD) and scanning electron microscopy (SEM).

This study was conducted to evaluate nutritional aspects of various edible fruit parts of jackfruit (Artocarpus heterophyllus) at different maturity stages based on fruit quality attributes, such as fruit age, Total Soluble Solids (TSS), reducing sugar, total sugars, mineral contents (Ca++, Mg++, Fe++, Zn++, etc) and vitamin contents. Further results clearly indicate significant difference in quality traits at different fruit maturity stages. Calcium content varied significantly in both edible parts with the time of maturity of fruit. TSS (290Brix) and total sugar (28.10%) was significantly superior and the reducing sugars (23.26%) and Ca 33.8mg/100g was also higher in the pulp at the fruit age of 75 days. While the highest Mg 36.96 mg/100g was at 85 days and Fe content was 4.24mg/100g at the fruit age of 45 days.

The present study documents the traditional knowledge of folklore medicinal plants that are in use in Jalaun district of Bundelkhand, U.P. India. Ethnomedicinal uses of 28 plant species along with their botanical name, vernacular name, family name and mode of administration are presented. They belong to 26 genera and 22 families. These plants used to cure 14 types of ailments. The study emphasizes the potentials of the ethnobotanical research and the need for the documentation of traditional knowledge pertaining to the medicinal plant utilization for the greater benefit of mankind.

 The cyclocondensation reaction between 2-benzamidoacetic acid I and o-methyl benzaldehyde afforded (Z)-4-benzylidene-2-o-tolyl oxazol-5(4H)-one 2. Then reaction of II with various benzothiazole derivatives III(a-f) was formed a series of novel benzothiazole combined imidazole compounds i.e.4-benzylidene-1-(substitued-2-benzothiazolyl)-2-(4-methoxyphenyl)-1H-imidazol -5(4H)-one IV(a-f). The novel synthesized compounds were characterized by elemental and spectral studies. All the novel synthesized compounds were screened for their antibacterial activities and antifungal activities.

Worldwide India is the major manufacturer and exporter of ethnomedicinal plants and plant extracts. The contribution of Odisha in this field is foremost. Plants are capable to synthesize a number of chemical compounds which kill and defend cancer cell growth. Concentration of researchers is on investigation of potent phytotherapeutic anticancer agents from various ethnomedicinal plants with minimal toxicities. The novel active constituents of anticancer herbs possess immune enhancing, free radical scavenging, antimutagenic, antiangiogenesis and anticancer properties. Mechanisms like enzyme inhibition, hormonal activity modulation, etc. give rise to the inhibition of cancer activities. Ethnomedicinally some significant plants of Odisha used against breast cancer, indicated through research are made to get detailed review here.

 The organic carbon content of all the three villages (Bodhapur, Gopikantapur and Tentulidhi) of Banpur block of Khurda district varies from  low to very high with a mean value varying from 0.39% to 0.85% and are good enough for crop production whereas in Bodhapur village the organic carbon content is found to be higher than other two villages. The available N content of all the villages are found to be low and is found to be in positive co-relation with the organic carbon content of the lands. The available P content of all soil in all the three villages is low. Therefore all the soils are phosphorus deficient. The available K contents of all the soils of Bodhapur village  are high except  the upland. This is a good indication to grow fruits, vegetables, and tuber crops which need a lot of K. The available K content of all the soils of Gopikantapur village ranges between low to medium. The available K contents of all the soils of Tentulidihi village range between low to medium. The S content is found to be comparatively higher in the low land soils of all the 3 villages under study. Again the S content is relatively higher in all the three types of land i.e. upland, medium land and low land of Bodhapur village in comparison to other two villages. The content of B in low land soils in comparison to the upland and medium land soils is found to be relatively higher.
Environmentally Benign Method for Estimation of Hardness in Water S. Chawla1, and R.K. Parashar2*
Int. J. Chem. Pharm. Rev. Res., 2015, 1(2), pp 49-54  •  Abstract  •  Fulltext    •   Citations: 0    •   Article Views: 0
Water hardness is defined as a measure of the amount of polyvalent metallic cations dissolved in water. Water with hardness above 200 mg/L causes scale deposition in pipes of the distribution systems. Soft water, with hardness less than 100 mg/L, has a bigger tendency to cause corrosion of pipes. For the estimation of hardness in water, main limitations in the widespread use of instrumental methods are high cost of instruments and need for skilled supervision for maintenance and operations. To overcome these limitations, a novel eco-friendly micro-titration method based on counting of number of drops is reported. The novel method utilizes conical flask and measuring cylinder both with integral funnel at their mouth. The green method was used for training of first year UG students. It needed only 10% of the time, saved ≥ 90% cost of the chemicals and is safe. Statistical comparison of the results with a conventional titration method shows an excellent agreement and indicates no significant difference in precision and accuracy.  The novel method is more environmentally benign.  It helps in saving cost, resources, time, energy and environment.
