1. Carbon Nnano Tubes: Past, Present and Future Trends

      Dr. Ayush Khare

      Nanotechnology is a group of emerging technologies in which the structure of matter is controlled at the nanometre scale, to produce new, interesting materials and devices with unique properties. Nanotubes belong to the promising group of nanostructured materials. Though there are many other tubes based on boron nitride and molybdenum but carbon nanotubes (CNTs) are most important group. Carbon nanotubes are among the most anisotropic materials ever produced. These molecular-scale tubes of graphitic carbon are one of the stiffest and strongest fibers known. Besides, they have remarkable electronic, optical, thermal and chemical properties.

    2. Engineered Fullerenerene Nanomaterials as Advanced Personalized Nanotheranostic System for Chemotherapeutics

      Debarshi Kar Mahapatra* and Sanjay Kumar Bharti

      Administration and therapeutic effectiveness of drugs is limited by several tribulations such as solubility, instability, targeting and side-effects which hoist health concerns for a long time. Nanomaterials have revolutionized this era and have all solutions of emerging troubles. Engineered Carbon Nanotubes are elongated fullerenes wrapped into cylindrical dimensions with a very high length to width ratio known potentially potential for drug delivery, discovery and theranostics.

    3. Novel Piperazine Coupled Benzimidazoles: Antimicrobial Evaluation

      Harish Rajak*, Chimay K Behera, Avineesh Singh, Vijay K Patel, Deepak K Jain

      Over the past few decades, gradually increasing drug resistance in the treatment of infectious disease indicate a crucial problem in antimicrobial therapy and necessitates continuing research into novel classes of antimicrobials. A number of researchers have reported antimicrobial properties in benzimidazoles. Keeping the these facts in view, we considered it of interest to synthesize some novel benzimidazole analogues for their antimicrobial activity. The structures of the compounds were elucidated using elemental analysis, IR, 1H-NMR and mass spectral data.

    4. Nano Sunscreen – The Wave of Future?

      Nidhi Yadav

      Who doesnot like a beautiful skin! UV radiation causes not only skin tanning, solar elastosis, lentigo, UV induced immunosuppression, skin aging but also skin cancers. Since umpteen years sunscreen have become the most popular means of protection against UV radiation. Most of the sunscreen block only one type of UV radiation i.e UVB but nano sunscreen blocks both UVA and UV B. Traditional inorganic sunscreens appear white on our skin. Many people don’t like how this looks.

      B. Keshav Rao* and Mohan L Verma

      First principle calculations based on density functional theory is performed to analyze the cationic interaction with the polyethylene oxide (PEO) based systems. The relaxed polymer structures are simulated, the analysis of partial density of states; density of states; bond lengths and the charge density distribution around interacting atoms is made. The structural and electronic properties of polymer systems are discussed; it takes into account of the cationic and anionic nature of the atoms of dispersed molecules.

    6. Hydrotropic Solubilizing Approach for Quantitative Estimation of Hydrochlorothiazide and Nebivolol Hydrochloride

      Ruchi Jain*, Nilesh Jain and Surendra Kumar Jain

      Two simple, accurate, novel, safe and precise methods developed for the simultaneous estimation of poorly water-soluble drugs Hydrochlorothiazide and Nebivolol Hydrochloride in tablet dosage form using 2 M Citric acid as hydrotropic solution. It was found that solubility enhanced of HCZ and NEB was more than 46 and 49 fold respectively in hydrotropic solution as compare with distilled water. HCZ and NEB show maximum absorbances at 271.5 and 280 nm respectively. Citric acid solution did not show any absorbance above 240 nm. HCZ and NEB follows the Beer’s law in the concentration range of 5-25 µg/ml and 30-150 µg/ml (r2= 0.9999 and 0.9987).

    7. An Overview on Bilayered Tablet Technology: A Review

      Evneet K. Bhatia*, Prabhanshu Vaishy, Ashwani Mishra, A.K Pathak

      Bi-layer tablets have been developed to achieve controlled delivery of different drugs with pre-defined release profiles. The introduction of bilayer tablet in the last decade had developed an interest in developing a combination of two or more active ingredients in a single dosage form in the pharmaceutical industry, promoting patient compliance and acceptance. Bi-layer tablet is suitable for release of two drugs in combination or inseparate layer for the delivery of two incompatible substances and also for sustained release tablet in which one Layer is immediate release as initial dose and second layer is loading dose.

    8. Fullerene: A Wonder Carbon Nanoparticle

      Gunjan Jeswani, Jigyasa Pal*

      The primary advantages of using carbon nanoparticle are their bioactivities which are not found in any other existing compounds. Fullerene is a carbon allotrope like diamond and graphite. All the electrons in fullerene are delocalized and spread over the whole molecule periphery as clouds. These electrons demonstrate antioxidative potency when they react with free radicals and active oxygen. Its use is not restricted to any one industry but can be extended to many other industries including cosmetics industry, non-linear optics, surface coatings, artificial photosynthesis and various biological applications including drug delivery and cosmetics.

    9. Chemistry of Dyes

      Kushagra Nagori*, Sonam Soni, Mukesh Singh

      The worldwide demand for natural dyes is nowadays of great interest due to the increased awareness on therapeutic properties of natural dyes in public. Natural dyes are derived from naturally occurring sources such as plants, insects, animals and minerals. Several synthetic colorants have been banned because they cause allergy like symptoms or are carcinogens. Among all natural dyes, plant based pigments have wide range of medicinal values. Although known for a long time for dyeing as well as medicinal properties, the structures and protective properties of natural dyes have been recognized only in the recent past.

    10. Upsurge of Nanotechnology in Dental Medicine

      Nupur Kar*

      The word nano is a Greek derived word meaning dwarf. It is a prefix that literally means one billionth of a physical size. Nanotechnology will give us the ability to arrange atoms as we desire and subsequently to achieve effective and complete control of the structure of matter.This upcoming field has the potential to drastically improve and replace the conventional dental materials used like impression material, implant material, bonding agents, composites with better esthetic properties. The development of nanodentistry will allow nearly perfect oral health by the use of nanomaterials and biotechnologies, including tissue engineering and nanorobots.
