The physiological status of in vitro-grown coconut (Cocos nucifera L.) plants during acclimatization was studied using nursery-raised seedlings as the control. The percentage of open stomata in leaves of in vitro-grown coconut plants was high at the

From the time immemorial coconut bunches were harvested at two monthlyintervals. In general two such bunches are harvested at a given harvest.However on the average a coconut bunch matures more or less everymonth. If these could be harvested at month

Precision in estimation and accuracy of the results from experiments is dependent on the nature of experimental variation. Controlling variation through calibration,. other than through local control, is a well defined concept since 1953. It is impor

We have studied the properties of InP self-assembled quantum dots embedded in various In0.49(AlxGa1−x)0.51P matrix layers to optimize the growth condition of the quantum dots and structures for III-phosphide quantum-dot-based lasers operating in vi

We report the characteristics of InP self-assembled quantum dots embedded in In0.5Al0.5P on GaAs substrates grown by metalorganic chemical vapor deposition. The InP quantum dots show increased average dot sizes and decreased dot densities, as the gro

Well-ordered arrays of pits were prepared on gallium arsenide and silicon wafers using a finely focused ion beam (FFIB). The defect pits on gallium arsenide, examined with tapping mode scanning force microscopy (TM-SFM), had a rim diameter of 60 nm a

We review the chemistry, microstructure, and processing of buried oxides converted from AlGaAs layers using wet oxidation. Hydrogen is shown to have a central role in the oxidation reaction as the oxidizing agent and to reduce the intermediate predic

In this letter, the nanoscale structure and chemistry of the III–V thermal oxide formed from Al0.49In0.51P is described. Transmission electron microscopy studies have shown that the oxide is an amorphous compound, which occupies greater volume than
