This work presents a comparison of the semiconducting properties and Schottky device applications of Co(ii)/Cu(ii) based coordination polymers.

A novel Zn(ii)-isonicotinohydrazido-thiophenyl based 2D coordination polymer reveals a drastic increase in electrical conductivity upon light irradiation and its application in anti-cancer activity.

The synthesis of solar-light-responsive zinc telluride (ZnTe) nanoparticles and their composite with reduced graphene oxide (rGO-ZnTe) via a simple hydrothermal reaction is reported. The synthesized nanostructures were comprehensively characterized by a combination of X-ray diffraction and photoelectron spectroscopy, electron microscopy, UV-vis spectroscopy, photoluminescence spectroscopy and thermogravimetric analysis. The effects of graphene oxide on the crystallinity, microstructure, photo-excitation, light absorption, surface area and thermal stability of ZnTe were studied. The current-voltage (

Congenital syphilis is caused by Treponema Pallidum. The fetus can acquire it transplacentally during maternal spirochetemia, or contact with genital lesion during the intrapartum period. The prevention and treatment of congenital syphilis are very much cost-effective, but if it remains undiagnosed and untreated, can result in a deadly outcome. It can affect multiple organs and systems. In this present case, skeletal systems were predominantly involved. The clinical presentation was the failure to gain weight, painful mobilization of the right arm, and swelling of the proximal and distal end of this arm. Erythematous, maculopapular scaly skin eruption was also noticed in the scalp and scrotum. Radiological examination showed metaphyseal irregularity, and periosteal reaction at the right humerus, radius, and ulna. Nontreponemal antibody test (VDRL) and a treponemal antibody test (TPHA) both were reactive. Early congenital syphilis may have a subtle clinical presentation or may remain asymptomatic. Therefore physicians should aware of the clinical presentation of congenital syphilis; at the same time, detailed clinical history can play an important role to suspect congenital syphilis. Promotion of pregnant women for antenatal care and screening for syphilis in the first trimester are the keys to eliminating congenital syphilis.

In this work, the synthesis of visible light sensitive copper sulfide (CuS) nanoparticles and their composites with carbon nanotubes (T-CuS) via a solvothermal technique has been reported. The synthesized nanoparticles...

Bangladesh is a country with a population of 160 million with a gross national income per capita of US$1580.00. The major health problems in Bangladesh include acute respiratory infection, pneumonia, dengue fever, malaria and water-borne diseases. The health care system in Bangladesh is divided into primary secondary and tertiary levels, with each level having their own breakdown of available hospital beds and other treatment facilities. Thalassemia is a major health problem in Bangladesh. There are two types of thalassemia in Bangladesh: β-thalassemia (β-thal) and Hb E (
