Synthesis and Characterization of Lead Chromate nanoparticles

CdS Deposited In Situ on g-C3N4 via a Modified Chemical Bath Deposition Method to Improve Photocatalytic Hydrogen Production

“…N-H bond stretching vibration of -NHx [33], while the weak peak observed at 3437 cm −1 was attributed to the O-H stretching vibration, likely due to the presence of hydroxyl groups or the physical adsorption of H2O molecules [34]. As for CdS, the spectrum exhibits distinct peaks at 3437 cm −1 and 1622 cm −1 , corresponding to the surface-adsorbed water molecules [35]. Additionally, the peaks at 1333 cm −1 and 1167 cm −1 are associated with the stretching vibration peak of Cd-S bonds.…”

تخليق وتوصيف جسيمات النحاس النانوية بالطريقة الكيميائية باستخدام حمض الأسكوربيك كعامل مخفض في وجود Metronidazole Benzoate (MTZ.B) (1- (2-benzyloxy ethyl) -5-nitro methyl imidazole) عقار

“…Three diffraction peaks were observed at 2θ = (43.47, 50.59 and 74.26) degrees corresponding to the" planes [111], [200] and [220] of face centred cubic (fcc) Cu metal "crystal lattice [21,22,23]. Average particle size has been estimated by using Debye-Scherrer formula equation [24,25]. D =_____k ._λ_____ β cos θ where 'D' is particle diameter size.…”

Removal and recovery of lead in a fluidized-bed reactor by crystallization process

“…34, Series of 1990, sets the criteria for lead at 0.05 mg/L for all on all surface waters with respect to water quality, water usage and classifications (DENR, 1990 salts (Refat 2004) and recently, lead carbonate nanoparticles have been synthesized by chemical co-precipitation method from lead (II) nitrate and sodium carbonate (Devamani and Raja Rajeswari 2014).…”
