The migration of antimony (Sb) from polyethylene terephthalate (PET) bottling for acidic juices have been assessed in this study. Inductively coupled plasma mass spectrometric (ICP-MS) method was chosen for antimony content determination. Experiments were undertaken at different conditions (15, 25, 35, 45days at 25, 50°C for first use bottle, reused bottle). Two different acidic juices (lemon j...

To estimate the field-emission current density of a germanium/silicon heterosystem, 20-nm Ge/Si(100) were grown by molecular beam epitaxy. The surface one sample was covered with layer antimony, which removed in vacuum prior to samples being measured. A second Ge/Si exposed room air absence antimony. current-voltage characteristics both obtained scanning tunneling microscopy discovered be agree...

pure and antimony doped sno2 thin films have been prepared by the sol-gel dip coating technique on glass substrate using starting material sncl2.2h2o as a host and sbcl3 as a dopant. our experimental results revealed that, the quality of the coated films on the glass depends on process parameters. the effect of annealing temperature, dipping numbers and the dopant concentration on the structura...

Smooth and compact Pb5Sb8S17 and Pb9Sb8S21 thin films were synthesized via sulfurization of unique layered precursor films of amorphous (Sb,S) and crystalline PbS; our syntheses suggest that these plagionite group phases are metastable and indicate that their formation does not require hydrogen incorporation.

Group III-V films are of great importance for their potential application in spintronics and quantum computing. Search for two-dimensional III-V films with a nontrivial large-gap are quite crucial for the realization of dissipationless transport edge channels using quantum spin Hall (QSH) effects. Here we use first-principles calculations to predict a class of large-gap QSH insulators in functi...

Diagnosis and therapy of cutaneous leishmaniasis (CL) can be difficult due to the variability of the clinical pictures and resistance to therapy. There is no vaccine currently available for CL. The aim of the present review is to describe different topical treatment modalities for old world CL. The mainstays of treatment for old world CL are penta...

2-(2"-Dichloroacetamidobenzyl)-3-(3'-indolylquinoline), designated indolylquinoline derivative A, reduced the splenic and the liver parasite burdens by >93.0% in Leishmania donovani-infected hamsters, whereas sodium antimony gluconate (SAG) reduced the burdens approximately 80.0%. Complete clearance of parasitemia from the livers and spleens was noticed when infected animals received indolylqui...
