Preparation and characterization of nano composites from metal oxides and activated carbon from banana peel (MO@BPAC, MO=NiO, CuO and ZnO) for 2 nitrophenol removal from aqueous solutions.

In this research, activated carbon from banana peel (BPAC) was prepared by calcination (600 °C) method. Nano composites MO@BPAC (MO=NiO, CuO and ZnO) were prepared and then were characterized by XRD, FTIR, FESM, EDX, BETand TGA methods. Formation of MO@BPAC nanocomposites was confirmed by analysis methods.

Density functional calculations of nickel, palladium and cadmium adsorption onto (10,0) single-walled carbon nanotube.

Adsorption of three heavy metals (Ni, Pd, Cd) onto (10,0) single-walled carbon nanotube (SWCNT) was investigated using density functional theory (DFT). Metals were adsorbed to both inside and outside of SWCNT and their structures and electronic properties [e.g.

Adsorption of CO molecule on AlN nanotubes by parallel electric field.

The behavior of the carbon monoxide (CO) adsorbed on the external surface of H-capped (6,0) zigzag single-walled aluminum nitride nanotube (AlNNT) was studied using parallel and transverse electric field (strengths 0-140 × 10(-4) a.u.) and density functional calculations.

10-Hydr-oxy-2-aza-penta-cyclo-[10.8.0.0.0.0]icosa-1(12),4(9),5,7,13,15(20),16,18-octa-ene-3,11-dione.

In the title compound, C(19)H(11)NO(3), the isoindolinone ring system is approximately planar with a maximum atomic deviation of 0.071 (1) Å and the five-membered ring of the dihydro-benzo[g]indol-3-one unit assumes an envelope conformation. The naphthalene ring system makes a dihedral angle of 39.

N'-(3,4-Dimeth-oxy-benzyl-idene)benzo-hydrazide.

The crystal structure of the title Schiff base compound, C(16)H(16)N(2)O(3), is characterized by chains of mol-ecules linked by inter-molecular N-H⋯O hydrogen bonds running along the c axis. Further stabilization is provided by weak C-H⋯O contacts. The dihedral angle between the aromatic rings is 38.
