Nanoscale texturing has been studied for various applications, but most of the methods used to make these nanostructures are expensive and not easily scalable. Some of these methods require etching steps or high-temperature processes, which limit the processes to certain materials, such as silicon. In this study, we report a non-etching nanoscale texturing technique that allows for controlled o...

A simple method for penetrating the barrier layer of an anodic aluminum oxide (AAO) film and for detaching the AAO film from residual Al foil was developed by reversing the bias voltage in situ after the anodization process is completed. With this technique, we have been able to obtain large pieces of free-standing AAO membranes with regular pore sizes of sub-10 nm. By combining Ar ion milling ...

Thermal property is the important material property for engineering and analysis of insulating materials. In this study, thermal conductivities of insulating materials are determined and compared with the literature values. Lee’s and Charlton’s apparatus is used to measure this property of insulating materials by steady state technique. This apparatus gives more precise result for insulators th...

The ripe fig (Ficus carica L) fruits of cultivar cv., 'Deanna' were steam treated at 90°C and 10 psi for 5 min in autoclave. Steamed fruits were dipped in sucrose, glucose, fructose and invert sugar syrups at 50°Brix for 24 h for getting desired total soluble solids content. The treated fruits were further dried to 20% moisture in a cabinet dryer at 50-55°C. Good quality and acceptable dried fi...

This study provides a set of nutritional and environmental parameters suitable for the growth of morel (Morchella crassipes) sclerotia in the laboratory, using a modification of the jar method of Ower et al. (U.S. patent 4,594,809, June 1986). The optimum nutritional and environmental conditions for morel sclerotium formation and maturation as determined in this study consist of a layer of rye ...

Four-day-old etiolated cucumber cotyledons (Cucumis sativus, L.) were excised and allowed to green in white fluorescent light at 28 C. Cotyledons excised with a full hypocotyl hook exhibited a lag phase of 1 hour before entering the rapid greening phase, whereas cotyledons excised without any hypocotyl hook exhibited a lag phase of 6 hours. Cotyledons excised with varying lengths of hypocotyl h...
