Photocatalytic degradation of phenol by oxidation, utilizing doped TiO2 (Fe/TiO2) as photocatalyst in the form of immobilized thin films in a jacketed photocatalytic batch reactor was the subject of this research. Fe/TiO2 photocatalyst was successfully synthesized using sol-gel method and coated on the chosen glass substrates using the wet coating method of dip-coating. Titanium isopropoxide wa...

In the present work, a novel 9Cr oxide-dispersion strengthened (ODS) steel powders with Y2O3 (0.5 wt%) dispersoids were synthesized by high planetary ball milling at different time intervals (2, 8, and 16 hours). The structural crystallographical evolution of produced during post-annealing treatment evaluated SEM, XRD, micro-Vickers hardness analyses. SEM results showed that fine dispersions ac...

Nanotechnology has been successfully used for the fabrication of targeted anti-cancer drug carriers. This study aimed to obtain Fe₃O₄ nanoparticles functionalized with Gemcitabine to improve the cytotoxic effects of the chemotherapeutic substance on cancer cells. The (un) functionalized magnetite nanoparticles were synthesized using a modified co-precipitation method. The nanoconjugate characte...

A nitrate-dependent Fe(II)-oxidizing bacterium was isolated and used to evaluate whether Fe(II) chemical form or oxidation rate had an effect on the mineralogy of biogenic Fe(III) (hydr)oxides resulting from nitrate-dependent Fe(II) oxidation. The isolate (designated FW33AN) had 99% 16S rRNA sequence similarity to Klebsiella oxytoca. FW33AN produced Fe(III) (hydr)oxides by oxidation of soluble ...

Introduction: The application of Fe- (BC-Fe) and Mg-modified (BC-Mg) biochars for the remediation heavy-metal-contaminated soil has become a research hotspot in recent years. It is critical to select suitable biochar rejuvenation under same pollution condition. Methods: In this study, were characterized by Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), scanning electro...

Six different perovskite-type oxides were investigated with respect to their ability for methanol synthesis via H2 and CO2: Fe-, Mn-, Ti-based perovskites prepared without Cu doping. For assessment, the catalysts subjected preliminary tests at atmospheric pressure evaluate activate CO2. Additional catalytic doped versions of each catalyst type carried out in a pressured reactor 21 bar. After me...

The principal intention of this work is to fabricate and characterize the polyamide/chitosan nanocomposite by a novel single solvent method through electrospinning procedure. thermal properties morphology prepared are studied thermogravimetric analysis (TGA) field-emission scanning electron microscopy (FE-SEM). TGA exposed that primary decomposition temperature reduced with rising chitosan cont...

Considering nutrient delivery and micronutrient use efficiency problems, mesoporous nanosilica (mNs) reduced graphene oxide (rGO)-based iron zinc nanocomposites were formulated. Prepared characterized for FTIR spectroscopy, XRD, FE-SEM, HR-TEM, AAS to examine surface functional groups, morphology, structural composition. XRD spectrum confirmation with SAED image of confirms the polycrystalline ...

An ancient wood layer dated at about 5600 yr BP by accelerator mass spectrometry (AMS) 14C was discovered in an intertidal zone of the East China Sea. Extensive and horizontally stratified sediments with black color on the top and yellowish-red at the bottom, and some nodule-cemented concretions with brown surface and black inclusions occurred in this intertidal zone. Microscale analysis method...
