A Review of P(St-MMA-AA) Synthesis via Emulsion Polymerization, 3D P(St-MMA-AA) Photonic Crystal Fabrication and Photonic Application: Ikhazuagbe Ifijen1; Esther Ikhuoria2; Stanley Omorogbe1; Aireguamen Aigbodion1; Salisu Ibrahim3; 1Rubber Research Institute of Nigeria; 2University of Benin; 3 Rubber Research Institute of Nigeria
The possible applications of photonic crystals (PhCs) in photonics and optics have increased their relevance in recent times. The propensity of PhCs to interact with light in their structure has led to a variety of thrilling and extraordinary features, which have shown possible usage in the generation of full-colour displaying films, coatings, switches, filters, photonic papers, responsive optical devices, etc. Polymeric materials have played an important part in the fabrication of PhCs owing to exceptional properties such as high strength, resistance to corrosion, resilience, colour, transparency, processing, and low cost. Among the utilized polymers, poly(styrene-methylmethacrylate-acrylic acid) (P(St-MMA-AA) has been utilized by several studies to generate photonic crystals with unique structural colours for photonic application due to the exceptional features introduced by its functional groups. This paper provided a brief explanation of the synthesis P(St-MMA-AA) colloidal particles via emulsion polymerization, 3D photonic crystal fabrication, and photonic application.
Enhancing Cutting Performance for Difficult-to-cut Workpiece by Oxide Hard Coating: Joonbong Lee1; Ki Buem Kim1; Taekjib Choi1; 1Sejong University
Advanced cutting tools for difficult-to-cut workpiece materials (i.e. titanium alloy) need long life time to require higher accurate process and lower production cost. Hard coating layers, consisted of metal-nitride, oxide and carbide, can be adopted to improve their cutting performances and wear resistance. During cutting process, the tools with only nitride hard coating layer occurs uncontrollable oxidation layer and internal thermal stress which can be caused poor life time issues. In order to improve coating properties, nano-crystalline oxide heterostructure is conducted on tungsten carbide based cutting tools. Furthermore, nano-laminated structures which consisted of mechanical enhancement oxide layer (Hf, Zr and Al based oxide) and functional oxide layer (V, Bi and Ti) can relieve internal stress on hard coating layer. They can improve mechanical properties of hardness, which are compressive macrostress generated during its growth, plastic deformation induced by dislocation, nanostructure of materials, and cohesive forces between atoms of neighboring grains.
J-1: Growth, Structure, Phase Stabilization and Optical Properties of Wide Band Gap Germanium Oxide Thin Films: Paul Nalam1; Debabrata Das1; Ramana Chintalapalle1; 1The Center for Advanced Materials Reserach, UTEP
Germanium oxide (GeO2), is a wide band gap metal oxide semiconductor, which exhibits exceptional thermal and optical properties. These properties offer tremendous potential for its application in next generation semiconductor electronics, optoelectronics and multifunctional devices. The current bottleneck in research of this material is lack in comprehensive understanding of this material for advanced applications due to the complexity of selective synthesis of a desired polymorph with controlled phase and properties. Here, we present an approach to successfully demonstrate nano-textured hexagonal and tetragonal phases of GeO2 film on Si substrates through a hybrid synthesis route, which involves film deposition by magnetron sputtering followed by post-deposition thermal oxidation. The resulting thin films exhibit exceptional optical band gaps at 6.21 eV for the α-quartz phase and 5.29 eV for the rutile phase. The evolution of h-GeO2 and t-GeO2 phases further analyzed using a variety of analytical methods to determine structural and functional properties.
J-2: Influence of Light Intensity and Temperature on Solar Cell Performance: Allyson Tarifa1; Aditya Barman2; Nuggehalli Ravindra1; 1New Jersey Institute of Technology; 2Middlesex County Academy for Science, Mathematics, and Engineering Technologies
The influence of varying light intensities and temperatures on theefficiency and overall performance of single-junction and multi-junction photovoltaic cells are analyzed based on the results in the literature. Solar cell performance as a function of light intensity, for three different semiconductor candidates (GaAs, CdTe, c-Si), are discussed and modeled. Experimental and model-based results of solar cell performance, as function of temperature, for various semiconductor material candidates are examined. Thermal management of solar panels from the perspective of applications of various approaches, including 2-D materials, are investigated.

Self-Assembly of Particles Adsorbed on the Drop Surface: Kinnari Shah1; Nuggehalli Ravindra1; 1New Jersey Institute of Technology
In this presentation, we will discuss some experimental results of self-assembly of particles adsorbed on the surface of drops. The particle arrangement is accurately controlled for a broad range of particles of various types, sizes and shapes adsorbed on the drop surface. Solid glass particles are utilized and an AC electric field is applied perpendicular to the interface. The movement of particles from pole to equator and equator to pole will be discussed. We show that the initial location of particles does not matter when they arrange on the pole or equator upon applying very low frequency fields. In the first case, initially, particles sit all over the surface; in the second and third case, particles are located more on the pole and equator, respectively. The behavior of particles suspended on the floating droplet will be analyzed at very low electrical frequency.
Utilization of Plant Oil Based-Fatliquor in the Processing of Leather: Ikhazuagbe Ifijen1; Isiaka Bakare1; Efosa Obazee1; Oghomwen Ize-Iyamu1; Nyaknno U. Udokpoh1; A. Ohifuemen1; F Mohammed1; E. Fagbemi,1; P Ayeke1; 1Rubber Research Institute of Nigeria
The chemical and mechanical steps in the leather-producing process-soaking, unhairing/liming, deliming/bating, pickling, tanning, neutralization/dyeing, fatliquoring, drying, and finishing-transform hides and skin into leather. The fatliquor, which is often injected into the collagen fibers to lubricate them without leaving an oily residue on the surface of the leather, is composed of many plants sulfonated oils. Plant sulfonated oil has been shown to improve the tensile strength, flexibility, and softness of leathers, as well as their lubricating capabilities. This investigation focused on the lubricating qualities of leather that had been treated with various fatliquored oils. The physicochemistry, difficulties, and potential uses of fatliquor in the manufacturing of leather were also emphasized.
