Journal: :Polymers & Polymer Composites 2023

A novel adsorbent material for the removal of Copper and chromium metal ions from aqueous solution was prepared by modifying chitosan. Cross linked chitosan using vanillin as a crosslinking agent further it incorporated with graphitic-C 3 N 4 to obtain polymeric matrix. The composite thus obtained characterized various characterization techniques such FTIR, TGA, SEM XRD. peak at 1658 cm −1 indi...

The colony-forming unit culture (CFU-C) in the thin-layer agar colony technique is considered to be representative for hemo-poietic stem cells (HSC), according to our studies in mouse and monkey bone marrow. Using this in vitro assay as a guide, stem cell concentrates were prepared from monkey and human bone marrow by repeated density gradient centnfugation. The number of CFU-C could be enriche...

Breast carcinoma is the leading cause of cancer death in women. Most of the time breast carcinoma presents as breast lump. Fine Needle Aspiration Cytology (FNAC) is a convenient and rapid preoperative diagnostic procedure. In this prospective study, FNAC was performed in patients presenting with breast lump and its findings were correlated with histopathological findings. Out of total 200 cases...

Pb(II) doped zinc oxide nanoparticles (Pb-ZnONPs) was synthesised using the co-precipitation method. The average size distribution of Pb-ZnONPs is 42.8 nm and further used as an adsorbent to remove Erichrome Black T (EBT) from wastewater. adsorption EBT onto best fitted for pseudo-second-order kinetics model, indicating that phenomena depend on Pb-ZnONPs, showing chemisorption phenomenon. maxim...

Abstract Banana, orange and potato peels (BP, OP PP, respectively) were immobilised to produce biosorbent beads that employed for the biosorption of heavy metals from a cocktail solution containing As(V), Cd(II), Cr(VI), Cu(II), Hg(II) Ni(II) ions. Drinking water conditions maintained with neutral initial pH low concentration Batch experiments performed evaluating effect in drinking range (6.5–...

A wide range of inflammatory as well neoplastic lesions can present cutaneous and subcutaneous swellings all over the body. FNAC (Fine Needle Aspiration Cytology) is considered to be first reliable technique for diagnosing them. To assess cytological spectrum presenting skin swellings. It was an observational study conducted in Department Pathology, Govt. Medical College, Jammu. performed on pa...

Abstract In the present study, thermally treated kaolinite at 600 ºC was incorporated with titanium hydroxide produced from ilmenite to prepare a novel, low-cost and promising adsorbent (KT). Different analytical techniques such as FTIR, EDS, SEM were used determine its structural analysis. Its applicability for uranium uptaking desorption aqueous solutions investigated by varying controlling c...
