Acid and Alkali Resistance of Polylactic Acid Incorporated Polyfurfuryl Alcohol Bioplastics
Abstract: PLA (0.5 to 3%) was successfully dissolved in furfuryl alcohol (FA). Acid number of neat polylactic acid (PLA) and PLA incorporated in FA were determined. Neat PLA and PLA incorporated polyfurfuryl alcohol based bioplastics were successfully fabricated with p-toulene sulfonic acid as an acid catalyst by casting method in silicon mould. The fabricated bioplastics are black in colour. The as-fabricated bioplastics were tested for resistance against acid and alkali. Additionally, …

Theoretical Calculation of Franck-Condon Factor and Dissociation Energy of Lithium Hydride Li7H1 and Li7H2 Molecule
Abstract: A theoretical spectroscopic study of isotopes of Lithium Hydreid Li7H1 and Li7H2 molecule for the electronic transition B1Π−X1Σ+ systems has been carried out such as, a calculation of Franck-Condon factor has been carried out by using numerical integration for the vibrational band v'=0–4 to v"=0–4 of the electronic transition B1Π−X 1Σ+ and it was found that the values of Franck-Condon factor for Li7H1 are higher than that of Li7H2 molecule. …

A Study of Hyperfine Interactions of Peroxy Radicals in Irradiated PE Copolymer at Low Temperatures
Abstract: Hyperfine interactions occurring around the magnetic environment of peroxy radical are investigated by electron spin resonance (ESR) technique. For this purpose, ESR spectra are recorded in the temperature range of 77 to 300 K. ESR spectra at 77 K possess some hyperfine structure together with peroxy doublet; while at high temperatures only peroxy doublet is observed. Hyperfine parameters like g-values, peak to peak separation, spread are calculated and their temperature …

LS-Coupled Atomic Term Symbols for nf7 Configuration
Abstract: In this manuscript, we described a simple method to obtain Russell Saunders atomic terms for nf7 configuration by microstate building and finally the splitting of LS terms, levels and states by different types of interaction represented pictorially. 3432 microstates in nf7 configuration resolve into 119 terms due to electronic interaction that are one (1) octet {8S}, six (6) sextets {6I, 6H, 6G, 6F, 6D, 6P}, forty (40) quartets {4N, 4M, …

Utilization of Waste Polyethylene Terephthalate with Bitumen for Road Construction
Abstract: Polyethylene terephthalate (PET) is commonly used for soft drink water bottles and other applications. However, disposal of this waste PET in large quantities causes environmental problem, as it is considered non-biodegradable material. This study investigated utilization of waste PET mixed with 60/70 penetration grade of bitumen to be as a raw material for road construction. The effect of temperature (140, 150, 160°C), composition of PET (4, 8, 12%) and mixing …

Experimental Demonstration on Fabrication Techniques and Recording of Leakage-free Surface-Driven Capillary Flow in the Dual Sudden Expansion Microchannels
Abstract: Dual sudden expansion polymethylmethacrylate (PMMA) microchannels have been fabricated by the maskless lithography, hot embossing lithography, direct bonding technique, and atmospheric pressure air dielectric barrier discharge (DBD) plasma processing. The surface-driven capillary flow of dyed water is faster on the processed PMMA surface than the pristine PMMA surface. The surface-driven capillary flow of dyed water is slower in the wider portion of any dual sudden expansion microchannel. This experimental demonstration …
