Materials science is a fast developing field of research in which a lot of advancements have been reported in few decades. The progress in materials science is essential due to its wide range of applications in solid state fuel cells, display materials, solar cells, energy storage devices, automotive sectors, electronics and environment, mechanical, medical & aerospace industries. Doping and substitutions in host materials are excellent ways of changing the properties of any materials. There are two main forms of materials, thin film and bulk, which are used in research. These two forms of materials are synthesized by two basic approaches, named as top-down and bottom-up. Bottom-up and top-down approaches are comprised of several synthesis methods, e.g., solid state reaction method, hydrothermal method, co-precipitation method, sol gel method, auto-combustion method, melt quench method, evaporation method, sputtering method, pulse laser deposition method, spin coating method and spray pyrolysis method. Each synthesis method has its unique procedure as well as merits and demerits. The solid state reaction route is one of the simplest synthesis method, which requires heating of the materials which were grounded for homogeneous mixing of the various oxide ingredients. The bulk and thin films at low reaction temperatures were prepared by sol-gel synthesis route which provides the high purity products. Co-precipitation method provides homogenous particle size which is a very energy efficient method. Thus, the synthesis method is an essential factor for materials science and nanotechnology research. The present article is an attempt to review the synthesis methods and their merits or demerits.

An important advantage of paper composites is their sustainability. Natural fibers store CO 2 during growth, they are recyclable and may be safely thermally recycled. In this work, composites out of laboratory paper and epoxy resin are generated in a hand lay-up process. The laboratory paper varies in the degree of fiber orientation. As a comparison, paper with isotropic fiber orientation is also used. The tensile strength for the isotropic paper composite is about 120 MPa. It can be observed that the tensile strength of the composite tends to increase with the increase of fiber orientation in the paper. The measured tensile strength of the oriented paper composites in the fiber direction is about 150 MPa and in cross fiber direction about 50 MPa. The strength characteristics are comparatively lower than for carbon or glass fiber reinforced composites, but the density of the paper composites investigated here is only about 1.26 g/cm 3 and the raw material price is significantly lower making paper composites economically attractive. At the end, strength values are modeled with the rule of mixture as well as with Kröling's strength model. In conclusion, tensile strength of oriented paper composites are higher than of isotropic paper.

Carbon nanotubes (CNTs) are particularly attractive for use in sensors for environmental and health monitoring. This study proposes a new approach in developing polymer-metal-based sensor for E. coli detection by using CNTs incorporation. PANI-SnO 2 nanocomposite thin films were combined with CNTs to be fabricated as biosensing devices. PANI-(SnO 2 ) 1-x -CNT x nanocomposite thin films were synthesized using sol-gel method and deposited on a glass substrate by spin coating technique. The prepared thin films were characterized by X-ray diffraction (XRD), field scanning electron microscopy (FESEM), atomic field microscopy (AFM) and ultraviolet-visible (UV-vis) spectroscopy. The sensitivity performance of PANI-(SnO 2 ) 1-x -CNT x nanocomposite thin films were conducted by using current-voltage ( I-V ) measurements. From the results, XRD patterns show the appearance of PANI, SnO 2 and C peaks and the increasing crystallite size with the increasing of CNT concentration. FESEM images show the spherical shape of SnO 2 and the nanotubes of carbon in the diameter size range 30 – 100 nm and 150 – 220 nm respectively. AFM analysis has found out the roughness parameter has increased when CNT percentage was increased. The peaks from UV-Vis absorbance bands indicated the presence of CNT and SnO 2 at wavelength 270 nm and 370 nm respectively. From I-V measurement of the sensor, PANI-(SnO 2 ) 1-x -CNT x with x = 0.03 performed the highest sensitivity which is 16.32%. The results demonstrate that the increasing of CNT concentrations was increasing the sensitivity of PANI-(SnO 2 ) 1-x -CNT x thin films towards E. coli .

The chemical processing of polymeric mixtures is a promising alternative for designing materials with new characteristics for biomedical applications. This work proposed to produce and characterize polymeric mixtures obtained using polyethylene glycol (PEG400 or PEG4000) with poly (L-co-D, L lactic acid)/PLDLA for biomedical use. The mixtures were prepared by the casting method. Characterizations were performed by Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), mechanical properties (perforation, resilience, elastic modulus, plastic deformation, tensile strength and mucoadhesion) and in vitro biodisintegration studies. The results obtained by FTIR and DSC suggest that the chemical interactions that generate the mixtures between the polymers occurred through hydrogen bonds and/or dipole-dipole interactions. Chemical interactions created compounds that were more hydrophilic and had different rearrangements when using PEG400 or PEG4000 in the mixture. The mechanical tests showed changes in the resistance of the materials, highlighting the exponential value of plastic deformation of PLDLA/PEG400, significantly increasing the plasticity of this structure by 111-fold about PLDLA/PEG4000. In the biodisintegration study, after 120 hours, greater mass loss was observed for PLDLA/PEG4000 (68.82 ± 1.46%). Hydrolytic disintegration did not influence pH values, which remained between 7.34 and 7.41 during the study. In conclusion, these mixtures can provide valuable characteristics to produce a biocompatible biomedical device with properties to support tissue regeneration, where the issue of plastic deformation is necessary in collaboration with the formation of pores, after PEG dissolution in vivo .
