Abstract

A series of Eu3+ doped MGd2Si3O10 (M = Mg2+, Ca2+, Sr2+ and Ba2+) was synthesized via sol-gel procedure at 950 oC. The optical characteristics of the materials were studied by Photoluminescence (PL) emission spectra. Upon 395 nm excitation and at 0.03 mole concentration of Eu3+ ion, these nanophosphors display optimum photoluminescence with most intense peak due to 5D07F2 (614-616) of dopant. Powder X-ray diffraction (PXRD) analysis proves that all synthesized materials are of crystalline nature and crystallinity improves on increasing temperature. Transmission electron microscopy (TEM) exhibited the spherical shape of particles in 13-30 nm size. Fourier Transformation infrared (FTIR) spectra showed peaks in 400-1000 cm-1 corresponding to gadolinium-oxygen and silicon-oxygen bond vibrations. In BaGd2Si3O10 material, Gd-O vibration is centered at 492 cm-1 and absorption band at 855 cm-1 is result of asymmetric vibrations of SiO in silicate tetrahedral unit. Due to excellent photoluminescence and suitable CIE coordinates, these materials could have brilliant applications in innovative displays.

Research Highlights

  • Series of trivalent europium doped MGd2Si3O10 (M = Mg2+, Ca2+, Sr2+ and Ba2+)fluorescent materials were synthesized successfully with sol-gel procedure.
  • The prepared samples were characterized using Photoluminescence analysis, X-ray diffraction study, Transmission Electron Microscopic analysis and Fourier Transform Infrared spectroscopy.
  • The CIE color coordinates values of phosphor confirmed the red color of complex approving the PL results.
  • X-ray diffraction pattern of these materials determined the particle size using Debye Scherrer’s equation.
  • Excellent photoluminescence response and nano size of these materials made them suitable for various innovative display applications.

Abstract

Doxorubicin (Dox), an antineoplastic drug, has been extensively used for the treatment of different cancers. Dox is hydrophilic and therefore distributes to normal organs at a faster rate. Due to its required high doses, it poses severe toxicity, such as cardiotoxicity and nephrotoxicity. Diverse approaches, including nanoparticulate delivery systems, have been designed and evaluated to improve its delivery to the target site and reduce toxicity to normal organs; however, this has met little success. Here in this review, we have discussed various systems (metal nanoparticles, carbon nanotubes, fullerenes, liposomes, dendrimers, cyclic peptides, and other covalent/non-covalent systems) that have been used for Dox. We have critically evaluated their designing and outcome (in vitro and in vivo) with potential applications in the clinical setting.

Nanochemistry and Nanocatalysis Science: Research advances and future perspective

Bhupender S. Chhikara, Rajender S. Varma

The development of nanomaterials has made its mark in nanocatalytic applications and ensuing plethora of nanotechnological advances. The size-dependent chemistry of nanomaterials and consequent controlled and designed synthesis of smart materials with desired end application has provided us a number of new products recently which are already making impact on quality of human life. The fundamental nano paradigm shift would influence future research advances in field of nanoscience chemistry, ranging from drug delivery to exquisite designs of novel catalysts that drive innovations in chemical synthesis and transformations.  The nanoscience is an interdisciplinary field that will see increased role in the diverse and emerging newer areas like artificial intelligence; nanochemistry would help speed up the development of applications in the real world with artificial intelligence.

Abstract

In this research work, we have synthesized blend of starch/PVA/nanoclay via solution cast method. The composition of blend was starch and PVA in 1:1 ratio by weight with citric acid as plasticizer. The amount of nanoclay was varied between 0.5 to 2 wt%. The structure elucidation of the film by Scanning electron microscopy reveals homogeneous dispersion of nanoclay into polymer matrix. The biodegradation of the films were studied by soil burial method and enzymatic hydrolysis and it was found that completely biodegradable films were produced which could serve as potential candidate for food packaging.

Development of reliable and eco-friendly synthesis of nanoparticles is a significant advancement for introduction nanotechnology to develop noble nanomedical delivery system of herbs (HNMDS), and have to overcome the downsides of old-style herbs-medicines delivery through analyzing the interactions between nanocarriers and herbs or phyto-medicine. The application of nanotechnological methods for bioavailability and biocompatibility enhancement of phyto-medicine must be reviewed and need urgent prompt efforts to develop new formulations. Nanotechnology enables the combination of hitherto separate approaches to health care by permitting the realization of so-called ’theranostic’ applications, as well as targeted combination products. Formulation must also release active ingredient from phyto-formulation as developing nano dosage forms has number of benefits for phyto-medicine. This review discusses nano sized herbs-nanomedicines delivery carries and potential current and futuristic advances for enhancing the activity and overcoming problems associated with herbal medicines for novel HNMDS.
