Growth Response and Humoral Immunity of Broiler Chickens Fed Organic Acids Zeolite Coated with Silver Nanoparticles under Heat Stress Conditions

The effects of varying the silica source on synthesis of NaX zeolite crystals via conventional hydrothermal method have been investigated. Five different silica sources were selected while other parameters like Al source, reaction and aging time, SiO2/Al2O3 molar ratio and temperature were same. The prepared products were characterized by XRD technique. The results showed that different cry...

Hybrid nanomaterials based on manganese, cobalt, and lanthanum oxides of different morphology phase compositions were prepared using a facile single-step ultrasonic spray pyrolysis (USP) process tested as electrocatalysts for oxygen reduction reaction (ORR). The structural morphological characterizations completed by XRD SEM-EDS. Electrochemical performance was characterized cyclic voltammetry ...

In the current work, Punica granatum L. peel, Artemisia herba-alba Asso., Matricaria chamomilla L., and Camellia sinensis extracts were used to prepare manganese dioxide (MnO2) nanoparticles utilizing a green method. Energy-dispersive X-ray (EDX) analysis, Fourier Transform Infrared Spectroscopy (FTIR) Filed emission-scanning electron microscopy (FE-SEM) analysis evaluate produced MnO2 NPs. FE-...

Self-pillared pentasil (SPP) zeolite is a hierarchically-structured zeolite comprised of single-unit cell thick MFI nanosheets arranged in a ‘‘house of cards’’ structure. The nucleation and growth of SPP proceeds through three phases involving the evolution of precursor amorphous nanoparticles to MFI nanosheets and then rotational intergrowth of sheets to produce the SPP morphology. This paper ...

The mechanism of self-assembly induced by H2O molecules is studied for layered saponite nanoparticles and zeolite with the cage structure by means of positronium (Ps) annihilation spectroscopy together with thermogravimetry and differential thermal analysis (TG-DTA). Prior to hydration the saponite exhibits two kinds of open spaces with their sizes of ∼3 Å and ∼9 Å, whereas open spaces with the...

Pt impregnated on a Sn-beta catalyst results in a very promising catalyst for the selective hydrogenation of α,β-unsaturated aldehydes, compared to the PtSn co-impregnated beta catalysts. Framework tin ions in the Sn-beta sample stabilize the nucleation of platinum nanoparticles inside the zeolite channel. These Pt(0)-Sn(4+) sites, which are only observed in the Pt/Sn-beta catalyst, have been s...

δ-MnO2/o-MWCNTs were synthesized by coating MnO2 spontaneously on oxidized multi-walled carbon nanotubes via simple immersion of the o-MWCNTs into KMnO4 solution. This catalyst comprising the outer region of catalytic MnO2 and the inner region of highly conductive o-MWCNTs enhanced photocatalytic water oxidation activity.

Still photography has a rich history of technological innovations to record the light in a scene dating back to the early 19th century (at least). The recent decades have seen these technological innovations create a revolutionary shift in the materials, processes, and uses of still images. Most of the still photography world has completed a move from silver halide (AgX) technology that dominat...
