We present a generic way of forming various complex polymeric microstructures using physical self-organization and capillary dynamics. A simple lithographic tool called capillary force lithography is utilized for this purpose, in which the pattern formation is driven by capillary force, not involving any external force or modification. In this method, a patterned polydimethylsiloxane mold is pl...

In this article, free vibration analysis of variable stiffness composite laminate (VSCL) plates with flat and folded shapes is studied. In order to consider the concept of variable stiffness, in each layer of these composite laminated plates, the curvilinear fibers are used instead of straight fibers. The analysis is based on a semi-analytical finite strip method which follows classical laminat...

An external rotor transverse flux motor using a combined-type stator core is proposed for a direct drive application in this paper. The stator core is combined by two kinds of components that can both be manufactured conveniently by generic laminated silicon steel used in traditional motors. The motor benefits from the predominance of low manufacturing cost and low iron loss by using a silicon-...

the northern sector of the Kent interlobate Complex, created by two major ice lobes of the Laurentide ice sheet during late Wisconsinan times, dominates the glacial landscape of northeast Ohio. the geomorphology of this impressive complex reveals the presence of large hummocks, kettle lakes and substantial esker chains. the esker chains, usually smaller than 1.3 km long, run parallel to the int...

Herein, eco-friendly natural acids inspired by nature, namely, acetic acid, formic lactic and citric acid on their capability of functioning as a p-dopant for the carbon nanotube transparent electrode in silicon-based planar heterojunction solar cells, are tested. From result, shows multifunctional effect p-doping with excellent doping stability well antireflection. The its investigated diverse...

The fatigue behavior of the unnotched and notched silicon carbide fiber-reinforced titanium/titanium aluminide hybrid laminated composite was investigated at room temperature. The evolution of microstructural damage and its effect on stiffness and strength degradation was quantified as a function of loading cycles and applied stress levels. Fatigue crack propagation behavior and damage mechanis...

This paper synthesizes data collected to document the modern limnological and sedimentary processes in South Sawtooth Lake located on northern Ellesmere Island, Nunavut, Canada. Field observations show that the finely laminated sediments deposited in the distal basin are formed by the settling of overflows and interflows, and in rare occasions, by non-erosive hyperconcentrated density flows. Th...

The mechanical properties of laminated window profiles manufactured using two types of adhesives were determined. The objective of this study is to evaluate the effects of heat treatment on some mechanical properties of laminated window profiles that manufactured from Kosipo (Entandrophragma candollei Harms.) using different type adhesives. Commercially produced polyurethane based Macroplast UR...

Wood veneer based composites have a great demand in present market as the material can utilize small diameter plantation timbers grown at short rotation cycle. This paper presents preparation and characterization of hybrid made wood polymer composite. The study explored utilization composite an adhesive for bonding veneers replacing formaldehyde-based adhesives. containing 40 % bamboo particles...
