The influence of InGaAlAs waveguide layer composition on the photoluminescence and electroluminescence in 1550-nm spectral range heterostructures based thin strained In0.74Ga0.26As quantum wells has been studied. An approach is proposed that allows analysis electroluminescence.to carry out a comparative deferential gain fabricated laser diodes. It shown decrease molar fraction aluminum layers m...

In this article, the anti-poison performance of novel Al-6Y-2P master alloy for impurity Ca in hypereutectic Al-Si alloys was investigated in detail. According to the microstructural analysis, it can be found that the primary Si and eutectic Si particles could be relatively modified and refined. In order to investigate the influence mechanism of Ca on the limited refinement performance of Al-6Y...

Procedures for the analysis of phosphorus in geological material normally aims for the determination of the total amount of P expressed as orthophosphate [Formula: see text] or the differentiation between inorganic and organic P. This is probably due to analytical difficulties but also to the prevalent opinion that the chemistry of phosphorus in geological environments is almost entirely restri...

Aluminium Phosphide poisoning and glucose-6-phosphate dehydrogenase deficiency are two commonly seen clinical presentations in Iran. However, hemolysis associated with Aluminium Phosphide poisoning is very rare. We report a case of concurrent Aluminium Phosphide poisoning and glucose-6-phosphate dehydrogenase deficiency in a 24 year old man presenting with intravascular hemolysis.

BACKGROUND Self-poisoning usually occurs by the ingestion of a single lethal compound and majority of the poisoning cases in our country are due to the pesticides. Suicide by ingestion of more than one poisonous substance is rare except alcohol and multiple drugs. To the best of our knowledge, suicidal ingestion of a mixture of rodenticide and battery acid has not been reported before in medica...

The main challenge for light-emitting diodes is to increase the efficiency in the green part of the spectrum. Gallium phosphide (GaP) with the normal cubic crystal structure has an indirect band gap, which severely limits the green emission efficiency. Band structure calculations have predicted a direct band gap for wurtzite GaP. Here, we report the fabrication of GaP nanowires with pure hexago...

The performance of solar cells (SCs) can be enhanced significantly by employing 2D photonic crystals (2D-PCs). They can either be used as omnidirectional, broadband antireflection coatings (ARCs) or applied to thin-film SCs (where PC effects are much more significant than in generic SCs). Although multilayer ARCs are commonly used, problems related to material selection, thermal mismatch, sensi...

A retrospective analysis of 584 cases of acute poisoning admitted with a medical emergency to the Department of Medicine, GTB Hospital, Delhi, over a three-year period. The patients were analysed with respect to the age, sex, mode of poisoning, type of poison consumed and mortality. Of these, 42.63% were aged 20-30 years. Poisoning was used as a suicidal agent by 63.8% of the patients. The natu...
