In this work, the synthesis of porous structure of cadmium oxide with multilayered sheet-like morphology in nano-meter size using adipic acid as soft template by solvothermal/thermal decomposition process is reported. Chemical analyses exhibited that the formation of porous sheet-like structure is originated from bidentate coordination mode of adipate units to Cd-center. It was found that the c...

Agar plate-based biofilm of enterobacteria like Escherichia coli is characterized by expression of the extracellular matrix components amyloid curli and cellulose exopolysaccharide, which can be visually enhanced upon addition of the dye Congo Red, resulting in a red, dry, and rough (rdar) colony morphology. Expression of the rdar morphotype depends on the transcriptional regulator CsgD and occ...

Nano hexagonal wurtzite ZnO has been prepared on zeoliteA by the sono-chemical method. The zeoliteA was mixed into Zinc gel, after stirring for two days, the mixture was irradiated 30 min by ultrasonic probe. The filtrated composite gel was calcinated at 500°C for 3h in furnace. The produced composite was characterized using X-ray diffraction, FT-IR spectroscopy and field emission scanning elec...

   ZnO structures with different dopants (1mol% Cr, Mn, Fe, Co, Cu and Ni) have been synthesized via a simple hydrothermal method using sucrose as a template. These doped ZnO nanostructures characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and photoluminescence (PL). The photocatalytic property of these synthesized materials was studied by a pho...

Nanostructured zinc oxide (ZnO) was successfully synthesized by precipitation method using the extract of Cylea barbata Miers (CBM) leaves as a soft template after 3 h of calcinations in furnace at 500oC in the open air. Characterization results showed that the nanostructured ZnO had hexagonal wurtzite structure with space group P63mc and nano-scale particle diameter. It was suggested that the ...

The effective removal of dyes from aqueous wastewaters is among the most important issues formany industrialized countries. Removal of Congo Red (CR) dye from aqueous solutions was studiedusing nickel oxide nanoparticles. The operating variables studied were initial pH of solution,adsorbents dosage, temperature and contact time. The morphological information of nickel oxidenanoparticles were ch...

BACKGROUND Hereditary diffuse gastric cancer (HDGC) is defined by germline mutations in the E-cadherin gene, CDH-1. The first family in which CDH-1 mutations were identified was a large Maori kindred, where lifetime penetrance is 70%. Prophylactic gastrectomy is an unacceptable option for many mutation carriers. The results of annual chromoendoscopic surveillance using the methylene blue/congo ...
