An experimental study of Resistance Spot Welding with CRCA sheet
Abstract: Resistance Spot Welding is prime process in automotive industries for joining metal sheets. Different materials are used for making automobile body. Now-a-days, cold rolled closed annealed(CRCA) sheets are used. In this paper, CRCA sheets for 1 mm. thickness is used for experimentation. D.O.E. is used and Input-output parameters are taken according to AWS D8.9M:2012 standard. Results are compared and final result having optimum output parameter is selected.

PREPARATION AND CHARACTERIZATION OF ACTIVATED CARBON FROM ORANGE PEELS
Abstract: In this study, an attempt was made to establish Green Energy from agricultural waste (orange peels). Activated carbon (AC) produced from orange peels with chemical activation agent i.e. phosphoric acid (H3PO4) by carbonization activation process. The influences of the process, carbonization temperature and activation temperature (600 °C) for time 2 hour with H3PO4 of 1:1 ratio on the resulting activated carbon properties were evaluated. The AC is an excellent adsorbent …

Passive Capillary Flow of Aqueous Working Liquids in the PMMA Microchannel Bends
Abstract: In this work, passive capillary flows or surface-driven capillary flows are recorded in polymethylmethacrylate (PMMA) microfluidic devices using aqueous ethanol and aqueous isopropyl alcohol (IPA) as chosen aqueous working liquids. Microchannel bends are the chosen microfluidic devices with the selected microchannel widths of 50, 120 and 200 micron. This work will be useful to fabricate the PMMA laboratory-on-a-chip systems for bioengineering applications.

COMPOSITION, RADIATION DOSE AND TEMPERATURE DEPENDENT DEGRADATION STUDIES OF POLYAMIDE 6 HOMOPOLYMER AND COPOLYMERS
Abstract: Composition radiation dose temperature dependency on free radicals generated in PA6, PA6/ PA12 copolymer, has been investigated by electron spin resonance (ESR) and FTIR techniques. ESR spectra of -irradiated PA6 has shown complex shaped and number of hyperfine lines is observed to be in between 6-10. This complex spectrum is assigned to macro-radicals of the type ~CH2CHCH2~, which in principle has to give a ten line ESR spectrum. However, due …

Light Weight Applications of Sandwich Panels in Various Industries
Abstract: Sandwich construction is of particular interest and widely used, because the concept is very suitable and amenable to the development of lightweight structures with high in-plane and flexural stiffness. Sandwich panels consist typically of two thin face sheets (or facings, or skins) and a lightweight thicker core. Commonly used materials for facings are composite laminates and metals, while cores are made of metallic and nonmetallic honeycombs, cellular foams, balsa wood …
