A new method named implicit pseudo-spectral arrays (IPSA) was developed to obtain the numerical solution and plotted it as a three-dimensional (3D) pattern. These results were used to elaborate the computational simulation of the spatiotemporal dynamics of the Swift-Hohenberg equation (SHE) of quintic order. Numerical solutions are employed as complex 3D computational models (computer-aided design file), which were studied and analysed to generate a new method named “mathematical design process and 3D printing assisted manufacturing (MDP-3DPAM)”. This new technique is a new way to create porous polymeric materials through a mathematical controlled shape with pore size distribution and microstructure modulated by software parameters. Another advantage of this design process is its efficient computational computation time, and the various 3D printing methods available such as fused deposition modelling and UV laser-assisted stereolithography. In this work, both techniques were used in the printing of porous materials. This work establishes a method for controlling pore size distribution through mathematical modelling and subsequent printing.

AnchorPlant mediated synthesis of metallic nanoparticles is an increasing commercial demand due to the wide applicability in various areas such as electronics, catalysis, chemistry, energy, cosmetics and medicine. In the present investigation, synthesis of gold nanoparticles is done by using fruit extracts of Ananas comosus (L.). Nanoparticles were characterized by using UV visible absorption spectra. Their morphology, elemental composition and crystalline phase were determined by scanning electron microscopy, energy dispersive X-ray spectroscopy and selected area electron diffraction. FT-IR analysis was used to confirm the presence of gold nanoparticles in the extracts. The synthesized gold nanoparticles were generally found to be effective as antimicrobial agents against some important human pathogens like E.coli and Streptobacillus sp. which are affecting and cause diseases like food poisoning and rat-bite fever to human beings respectively.

Fungal infections are major issue in agricultural crop plants that affects the growth of plant causing huge economic losses. Silver nanoparticles (AgNPs) have shown antimicrobial effects. Here, we report the potential application of phytostabilized AgNPs as a novel nanofungicide and growth promoter in Vigna radiata (L.) R. Wilczek (Mung). The aqueous extract of Azadirachta indica (Neem) challenged with AgNO3 (1mM) develops a brown colour, indicating AgNPs synthesis. Detection of AgNPs was monitored by UV-Vis spectroscopy, which showed peak at 415 nm. Further confirmation was done by Fourier Transform Infra-Red Spectroscopy which illustrates functional groups present in the capping proteins. Nanoparticle Tracking Analysis, and Transmission Electron Microscopy confirmed the synthesis of spherical, polydispersed nanoparticles in the range of 15-35 nm. AgNPs proved to exhibit antifungal potential in suppression of fungal plant pathogens. Seed germination percentage was much higher for the AgNPs treated seeds as compared to control. Handy-PEA analyzer (measures chl-a fluorescence) indicating seedlings inoculated with AgNPs were grown as the healthy plant with greater vitality, compared to control plants. Phytostabilized AgNPs were found to be biocompatible and have a promising attribute in developing a potent nanofungicide to enhance productivity rate and prevent fungal infections in crops with no potential toxicity.

Solid-state thermochromic materials undergo semiconductor to metal transitions at a ‘critical temperature’, Tc. This review begins by describing the phenomenon of thermochromism, whereby the optical properties of a material change reversibly as a result of a change in temperature. The various different types of thermochromism will be introduced with a focus on the thermochromism exhibited by solid-state materials. The fundamental chemical principles that describe the electronic structure and properties of solids, and the chronological developments in the theory behind the thermochromic transitions (such as, the effects of electron-electron interactions and structural phase changes due to lattice distortions) that led to the discovery of the semiconductor-to-metal transition, are presented. An extensive discussion of vanadium and titanium oxides is presented with a particular focus on vanadium (IV) oxide since its transition temperature is closest to room temperature. Observations and current understanding of the nature of the semiconductor-to-metal transition exhibited by these materials is detailed. The possibility of fine-tuning the transition temperature by introducing various dopants into the vanadium (IV) oxide lattice is examined and the effects of dopant charge and size is examined. Solid-state thermochromic materials may be exploited in areas such as microelectronics, data storage, or intelligent architectural glazing, thus are required to be synthesised as thin films for use in such applications. The numerous synthetic techniques (PVD, sol-gel method, PLD, CVD, APCVD and AACVD), for making metal oxide thermochromic thin films are described in reference to the production of vanadium (IV) oxide and compared. Finally rare earth nickelates exhibiting thermochromism are described.

The undertaken study describes synthesis of air resistant copper nanoparticles (Cu NPs) in an aqueous phase using sodium borohydride as a reducing agent via chemical reduction method. The hydrosol has resistant to oxidation by atmospheric oxygen for several days. The air stability was induced by capping Cu NPs with anionic surfactant “sodium dodecyl sulfate (SDS)”.  Ascorbic acid was used as an antioxidant. These Cu NPs were characterized by ultraviolet-visible (UV-VIS) spectroscopy, which contributed towards the understanding of surface plasmon resonance (SPR) generation and optical behavior of Cu NPs. It was used as an optical tracer for size control and confirmation of Cu NPs and was found to be affected by various parameters like reaction time, pH, concentration of copper sulfate and the surfactant SDS. SPR peaks were found to shift from 597 to 569 nm, while apparent color changes from yellow to brick red.  Further characterization studies were carried out by using fourier transform infrared (FT-IR) spectroscopy to investigate the co-ordination between Cu NPs and SDS. X-ray diffraction (XRD) was used for phase purity of Cu NPs. Transmission electron microscopy (TEM) and atomic force microscopy (AFM) were used the size and morphological characterization. The average size of the Cu NPs was found to be 15 nm in diameter with an average height of 14 nm. The Cu NPs showed excellent catalytic activity in the reductive degradation of Eosin B (EB) dye in just 16 sec of reaction time and maintained their catalytic activity when reused multiple times. The degradation rate was found to follow first order reaction kinetics with the EB degradation. The Cu NPs enhanced the rate of EB degradation 30 times more than the control test. Copper was found an attractive catalyst in the nanosize regimes. The Cu NPs are more economical as compared to noble metals. The Cu NPs are expected to be suitable alternative and play an imperative role in the fields of catalysis and environmental remediation.
