Cu( II ) ions removal from wastewater using starch nanoparticles ( SNPs ): An Eco‐sustainable approach
PublicationThe complex structured starch particles were reduced to the nanoscale size range through hydrolysis utilizing low concentration acid assisted with ultrasound irradiation. The synthesized starch nanoparticles (SNPs) were characterized by TEM, FTIR, and XRD techniques. The synthesized SNPs possessed surface activated entities, as many cationic functional groups were confirmed through the FTIR spectrum. Also, these SNPs were effectively...

Synthesis of bimetallic Co–Pt/cellulose nanocomposites for catalytic reduction of p-nitrophenol
PublicationIn this study, bimetallic nanoparticles (NPs) of Co–Pt anchored on cellulose nanofibers (CNFs) for catalytic applications were synthesized via a sonochemical approach. The electro-spinning technique was employed for the synthesis of CNFs from cellulose acetate. The thorough characterization of synthesised Co–Pt/CNF nanocomposites was performed with the help of scanning electron microscopy (SEM), Fourier transform infra-red (FT-IR)...

BET of TiO2 heated at 400-600 C degrees
Open Research DataThese data refer to the results of BET surface area of TiO2, which was treated firstly in autoclave at 150 C degrees for 1h (sample marked as A150), then was further heat treated in Ar or H2 at 400-600 C degrees. As a raw material TiO2 was used, which was a semiproduct from the industrial production of titania white by sulphur method. The raw material...

Realizacja przetwornika obrazu CMOS z wbudowaną konwersją A/C i cyfrowym układem CDS
PublicationW artykule przedstawiono realizację w technologii CMOS 180 nm przetwornika obrazu z wbudowaną konwersją analogowo-cyfrową oraz z funkcją cyfrowej redukcji szumu. Przedstawiona realizacja przetwornika obrazu różni się od znanych z literatury rozwiązań tym, że układ redukcji szumu CDS (Correlated Double Sampling) umieszczono w każdym pikselu obrazu. Dzięki tej modyfikacji możliwe jest zastąpienie migawki szczelinowej przez migawkę...

Bulk linearized CMOS differential pair transconductor for continuous-time OTA-C filter design
PublicationIn this paper, the MOS differential pair driven simultaneously from gates and bulk terminals is described. An approximated analytical solution of the voltage to current transfer function has been found for the proposed circuit. Four possible combinations of gate and bulk connections of the input signal are presented. Basing on the configuration giving the best linearity, the operational transconductance amplifier (OTA) has been designed...
