Ecofriendly adsorbent materials for the rapid and efficient removal of pollutant dyes are highly desired on account concerns about environmental pollution human health. Herein, novel magnetic HC/Fe3O4 spherical have been constructed via crosslinking hydroxyethyl cellulose (HC) by poly(ethylene glycol) diglycidyl ether (PGDE) followed introduction Fe3O4 a facile effective strategy developed in t...

Magnesium Ferrite (MgFe2O4) spinel structures prepared by a solid-state reaction was used as an anode modifier in the microbial fuel cell (MFC) treatment of Congo red dye. The performance reactors with unmodified stainless-steel mesh (CR-1) and MgFe2O4 coated stainless steel (CR-2) were tested compared followed aerobic treatment. peak power density observed to be 295.936 430.336 mW/m2 revealing...

Poly(ethylene glycol) (PEG)-decorated polystyrene (PS) nanoparticles with mean hydrodynamic diameter (D) and zeta-potential (ζ) of (286 ± 15) nm and (-50 ± 5) mV, respectively, were modified by the adsorption of Congo red (CR). The PS/PEG/CR particles presented D and ζ values of (290 ± 19) nm and (-36 ± 5) mV, respectively. The adsorption of lipase onto PS/PEG or PS/PEG/CR particles at (24 ± 1)...

In this work, we present the stabilization of polar step edges along the [010] direction of calcite (10.4) by the presence of a water-soluble organic molecule, namely Congo Red. While characteristic etch pits are observed on the surface in the absence of the additive, no etch pits can be found in the presence of the additive. Using atomic force microscopy, we can directly follow the restructuri...

OBJECTIVE To describe a new, quantitative, and reproducible method for detecting deposits of amyloid A protein in aspirated fat tissue and to compare it with smears stained with Congo red. METHODS After extraction of at least 30 mg of abdominal fat tissue in guanidine, the amyloid A protein concentration was measured by a monoclonal antibody-based sandwich ELISA. RESULTS The concentrations ...

This study reports decolorization of Rhodamine B and Congo red by a partially purified laccase from Lentinus polychrous Lév. in the presence or absence of 2,2-azinobis (3-ethylbenzothiazoline-6sulfonate) diammonium salt (ABTS) as a redox mediator. The decolorization study showed that about 90% of Rhodamine B could be decolorized within 52 h, whereas Congo red could be decolorized more than 75% ...

An alternative method for detecting the production of slime by coagulase negative staphylococci was compared with the routinely used Christensen method on 124 isolates ofcoagulase negative staphylococci from carriage sites, blood cultures, and infected peritoneal dialysis fluids. The alternative method requires the use ofa specially prepared solid medium-brain heart infusion broth, supplemented...

A large number of microorganisms are capable of degrading cellulose, only a few of these microorganisms produce significant quantities of enzymes capable of completely hydrolyzing cellulose. Fungi are the main cellulase producing microorganisms. In this purposed study, four fungal species belonging to two genera i.e. Trichoderma and Aspergillus were isolated from different sources, screened and...

A punch biopsy of the axillary region was performed for histopathological study, staining with hematoxylin-eosin (Figure 2), periodic acid-Schiff (PAS), and Congo red. The histological findings included papillomatosis, orthokeratotic hyperkeratosis and epidermal acanthosis, focal atrophy of the granular layer, and mild hyperpigmentation of the basal layer of the epidermis. There was a moderate ...

We present a new laser system and nonlinear microscope, designed for differential nonlinear microscopy. The microscope features time-correlated single photon counting of multiphoton fluorescence generated by an alternating pulse-train of orthogonally polarized pulses. The generated nonlinear signal is separated using home-built electronics. Results are presented on fluorescence-detected nonline...
