Ankita Singh^* and Sanjeeve Thakur

Netaji Subhash University of Technology, India

Countable no of efforts has been made in research to study the composites of Molybdenum diselenide (MoSe₂) and reduced graphene Oxide (Gr) in the Photovoltaics. Here, MoSe₂/Gr hybrid has been synthesized by facile hydrothermal route where two different synthesis approaches have been involved to account for the variation in the interaction of two materials. For the first method opted, precursors have been used with the reduced graphene oxide whereas in the other method already synthesized molybdenum diselenide has been used directly with reduce graphene oxide. The aim of study is to look into the morphological distribution and interaction between the TMDC and the reduced graphene oxide and the possible effects of synthesis methods on the device efficiency. The morphological study has been obtained by optical microscopy and scanning electron microscopy (SEM). Diffraction light scattering technique (DLS) performed the average mean Size of the particles and the physico-chemical characterization included Raman for the structural fingerprint and different modes of vibration, XRD for the estimation of diffraction peaks and crystallite size.

TPE-Based AIE-Active Smart and Soft Materials for Sensing and Imaging Applications

Mainak Banerjee^*, Viraj G. Naik, Vikash Kumar and Amrita Chatterjee

Department of Chemistry, BITS Pilani, India

Fluorescent probes, in particular, emission based fluorescent “light-up” probes are important tools in the field of bio-medical applications. Tetraphenylethylene (TPE) is the most useful scaffold in making several luminescent materials because of its inherent aggregation induced emission (AIE) property. Recently, growing interests have been shown in designing TPE-amphiphiles derived smart nanoaggregates (e.g. vesicles, nanoparticles) because of their multi-targeting and better binding abilities other than unique encapsulation capabilities for better performance in sensing, delivery, bioimaging, diagnostics and theranostics [1]. These TPE based probes could become more water soluble and bio-compatible by incorporating glycol units in the chain and cationic pyridinium unit at the terminal respectively so that they would be more suitable for biotechnological applications. This unique feature provides an opportunity to design light-up probes as multipurpose auto-fluorescent tool for bio-applications particularly in sensing and cellular imaging.

The present talk mainly focuses on the design and synthesis of various water-soluble TPE-amphiphiles with varying spacers, their unique aggregation behaviors in aqueous solutions, fluoremetric detection and quantitation of biomacromolecules such as protein and DNA, detection of bacteria by electrostatic interactions (Fig. 1) [2]. The talk will also cover other TPE-amphiphiles for selective fluoremetric detection and quantitation of biomacromolecules and imaging studies [3].

Preparation of Polycaprolactone, Hydroxyapatite with Alendronate Hybrid Nanocomposite for their Potential use in Bone Tissue Engineering Application

Deepak Poddar^* and Purnima Jain

Netaji Subhas University of Technology, India

Biomimetic polymeric scaffolds using polycaprolactone (PCL) as a matrix with hydroxyapatite (HAP) and alendronate (ALD) composite were fabricated using porogen leaching technique. The scaffolds were designed in two steps. Initially, HAP was functionalized with ALD using co-precipitation method to enhance the bioavailability of the drug in composite and in the second step, modified HAP (MHAP) nanoparticles were loaded into the PCL which leads to the formation of scaffolds. Physicochemical characterizations manifested the attachment of HAP with ALD and it was confirmed using 1H NMR study along with XRD and FTIR, which also evidently validated for the functionalization of the ALD in the composite. The wt% of ALD and MHAP in the composites, as well as in scaffolds respectively was determined using TGA studies. Scaffolds exhibited remarkably improved mechanical strength and exhibited tuneable enzymatic degradation behaviour in lipase. In Vitro cytotoxicity and proliferation showed the scaffolds promote the adhesion and growth of bone marrow cells onto its surface. Scaffolds with appropriate mechanical strength and tunable degradation rate with enhancing cell growth hold the potential as used in bone tissue engineering.

Carbon- Based Platforms for Sensory Applications

Amrita Chatterjee^*, Bhaskar Priyadarshi and Mainak Banerjee

Department of Chemistry, BITS Pilani, India

Graphene oxide (GO) and its reduced form (rGO) have received huge research attention not only because of its unique surface properties but also for its diverse application potential in fields like electronics, biomedical applications, sensors, adsorbents, catalysts, etc. [1]. On the other hand, carbon dots (CDs) have recently emerged as a promising carbon-based nanomaterial with impending applications in various fields, e.g. sensing, bioimaging, catalysis, etc. [2]. In particular, their ecofriendly synthesis, high water solubility, low toxicity, excellent biocompatibility make them sustainable alternatives for the present and future. It is interesting to note that these carbonbased materials possess inherent fluorescence which allows them to be used as label-free fluorescent probes for various “sensory applications”. Often, a judicious choice of quencher/promoter leads to an efficient sensing platform for selective and sensitive detection of analytes. Sometimes, their conjugation with another nanomaterial (e.g MnO₂ nanosheets) is helpful in devising sensing platforms. One of the present research focuses of our laboratory is the development of various carbon-based nanocomposites as efficient sensory platforms for various toxic analytes. For example, an rGO-thioguanine based fluorescent sensing platform was recently developed in our laboratory for label-free detection and discrimination of inorganic and organic mercural in aqueous media. On the other hand, CDs-MnO₂ nanoconjugate can be utilized for the detection of hydrazine (Fig. 1) [3, under revision]. The talk will also cover a glimpse of our research in “sensing and imaging” for the last few years.

Nickel-Incorporated Mesostructured Cellular Foam Catalyst for Selective Conversion of Fatty Acid Distillate into Diesel-Like Hydrocarbon Fuels

Ahmad Zuhairi Abdullah

Universiti Sains Malaysia, Malaysia

Oleochemical wastes, especially fatty acids and fatty acid distillate are seen as renewable fuel sources of the future. Owing to high molecular weight of the fatty acid feed, the catalyst materials should be designed to have high surface area, sufficient framework mesoporosity, high structural strength and narrow pore size distribution. Mesostructured cellular foam (MCF) support was synthesized using a sol gel method with tetraethyl ortho silicate (TEOS) amounts ranging from 9.2 to 16 mL and then aged for between 1 to 3 days. Nicked-incorporated MCF catalysts were subsequently prepared using a precipitation. The physicochemical properties of the MCF catalysts were then elucidated by means of N₂-adsorption, energy dispersive X-ray (EDX), transmission electron microscopy (TEM), Fourier-transformed infrared (FTIR), thermal gravimetric (TGA) and H₂-temperature programmed reduction (H₂-TPR) methods. The catalytic activity was measured based on the semi-batch conversion of palmitic acid (PA) by the catalyst (10% wcat/wPA) carried out at 300 °C for up to 6 h under nitrogen flow. The window pore size of the MCF generally increased with increasing aging time. The increase in the TEOS amount up to 12.5 mL evidently decreased the pore volume, cell size and window pore size due to the increasing thickness of the MCF mesostructure. The incorporation of nickel generally led to slight decreases in the textural parameters. NiMCF(9.2T-3D) that was prepared with 9.2 mL TEOS and aged for 3 days was the most active catalyst, attributed to its high nickel content (17.6%) with the smallest particle size. Furthermore, the yield of 1-pentadecene in the product showed corresponding increases while those of n-pentadecane remained relatively constant. This was attributed to the formation of more CO gas that could inhibit the palmitic acid decarboxylation reaction. 30.9% n-pentadecane yield and 33.7% 1-pentadecane yield were recorded.

Keywords: Palm fatty acid distillate; decarboxylation; hydrocarbon; renewable fuel; Ni-loaded MCF catalyst; synthesis conditions; physicochemical characteristics.

Lithium sulfur batteries with high charge-discharge rate capabilities are in great demand for hybrid vehicles, electric vehicles and portable electronic products. However uptill now its real applications are still plagued by rapid capacity fade mainly stemming from the polysulfide shuttle. High rate capability can be often enhanced by downsizing cathode materials to the nanoscale which increases the reaction surface to volume ratio but downsizing to less than 100 nm reduces the capacity. Ferroelectric materials have attracted much attention due to their unique ferroelectric, piezoelectric and ferroelastic properties. Coupling of highly polarized ferroelectric (BiFeO₃) layer is an approach that can be used to enhance the higher rate characteristics and trapping of shuttle mechanism because ferroelectrics provides higher polarization which help to build up an internal electric field and induces macroscopic charges on the surface of the cathode. In Li-S batteries during discharge polysulfide shuttle causes capacity fade of the battery. We can speculate that polysulfideʼs are heteropolar in which spontaneous polarization of ferroelectrics (BiFeO₃) may solve the shuttle effect and can trap its formation for high rate performance Li-S batteries.

Introduction: The repair of cartilage lesions constitutes a major challenge in regenerative medicine since the current clinical solutions are limited. Therefore, tissue engineering which aims to create novel and improved tissue and organ substitutes has evoked increasing interest for cartilage repair. The discovery of mesenchymal stem cells (MSCs) catalyzed the fields of tissue engineering and regenerative medicine. But although stem cells hold great potential for the treatment of many injuries and degenerative diseases, several obstacles must be overcome. These include the development of advanced techniques of novel methods to track and guide transplanted stem cells. Our work had focused on creating tissue in the laboratory for implantation repair knee cartilage lesions.

Methods: Adult stem cells were isolated from bone marrow of animal model, expanded in culture as per the protocol standardized in our laboratory. Osteoarthritis (OA) was induced unilaterally in the knee joint of donor animals. Then the stem cells implanted with (nano+) and without Nano fibrous scaffold (nano-) and injected in the injured knee to test their effect. Control animals received sodium hyaluronan alone.

Results: Stem cells survived well and showed stable division in culture, making them ideal targets for In Vitro manipulation. The isolated cells possessed the basic features of MSCs. The examination of the treated models showed decrease in overall pain, pain upon limb examination, improvement in gait, performance in daily life activities and vitality with reduction in gross pathological cartilage changes and repair of articular cartilage to histologically normal appearance expressed earlier one week in the nano+ group.

Conclusion: There is a great promise to advance current cartilage therapies toward achieving a consistently successful approach for curing cartilage agonies. Tissue engineering may be the best way to reach this objective via the use of stem cells, novel biologically inspired scaffolds and emerging nanotechnology.

It is admitted that Liquid-Phase Pulsed Laser Ablation (LP-PLA) attracts more and more much attention and has been presented as an effective and innovative method of synthesis of functional nanoparticle materials. In our previous study, we have shown that the concentration of produced nanoparticles is linear with time, meaning that the production of nanoparticles by Pulse Laser Ablation is a controllable and precise process. This paper completes the first study by carrying a particular attention on average size estimation of the generated nanoparticles. The study is based on the use of a simple Multi Angle Near-Infrared Light Scattering (MA N-IR LS) device, which in real time, estimates easily by transmissometry and dual angles nephelometry, the average size of copper and iron nanoparticles produced by LP-PLA process. The developed experimental setup, mounted on a simple electronicʼs instrumentation board and a specialized software has shown that the method can be easily used to estimate size evolution of produced nanoparticles; justified by the fact that our experimental curves can be correlated to the size of Cu and Fe nanoparticles, present in the aqueous medium. The software implements Beer-Lambert law and Rayleigh theory at two different angles which, after the nanoparticles concentration calculation, evaluates their average size, based on exploitation of the reverse equations correlated to the concentration after multi-angle observations. With our integrated device, only three angles of light scattering theories are sufficient to evaluate judiciously the global size of the nanoparticles generated during a Femto-Second Laser Ablation process. The users would just have to correctly install our device in the laser ablation process plan.
