Various potentially toxic element tolerances in different rice genotypes correlate with distinct physiological responses and alterations in DNA methylation.

Potentially toxic elements (PTEs) are harmful to plant growth and reduce crop productivity. In this work, we studied three rice genotypes (T-35, RZ-1, and RZ-2) to quantify the diverse PTE effects and tolerances by examining morphology, physiology, and DNA methylation patterns. Morphological results showed that T-35 exhibits the highest tolerance to all studied PTE stressors (Cu, Cd, Cr).

Adsorption of p-chlorophenol on three amino-modified hyper-cross-linked resins.

Three amino-modified hyper-cross-linked resins (HCP-M, HCP-E, and HCP-D) were synthesized, and they were evaluated for adsorption of p-chlorophenol from aqueous solution. The results indicated that the uploading amounts of the amino groups on the three resins followed an order of HCP-M View Article and Find Full Text PDF

Hydrophobic-hydrophilic post-cross-linked polystyrene/poly (methyl acryloyl diethylenetriamine) interpenetrating polymer networks and its adsorption properties.

In this study, we developed an effective approach for increasing the equilibrium adsorption capacity of the interpenetrating polymer networks (IPNs) toward polar aromatic compounds. For this purpose, a novel post-cross-linked polystyrene/poly (methyl acryloyl diethylenetriamine) (CMPS_pc/PMADETA) IPNs was synthesized and its adsorption was evaluated from aqueous solution using p-hydroxybenzoic acid as the adsorbate. CMPS_pc/PMADETA IPNs possessed a relatively high Brunauer-Emmett-Teller (BET) surface area and hydrophobic networks as well as hydrophilic networks, inducing a much enhanced adsorption toward p-hydroxybenzoic acid.

2-Fluoro-N'-[(2-meth-oxy-naphthalen-1-yl)methyl-idene]benzohydrazide.

The asymmetric unit of the title compound, C(19)H(15)FN(2)O(2), contains two mol-ecules, A and B, in which the dihedral angles between the ring systems are 46.4 (2) and 17.24 (14)°, respectively.

3-Bromo-N'-[(2-meth-oxy-naphthalen-1-yl)methyl-idene]benzohydrazide.

The mol-ecule of the title compound, C(19)H(15)BrN(2)O(2), displays a pseudo-trans conformation about the N-N bond [C-N-N=C torsion angle = 164.7 (2)°]. The dihedral angle between the planes of the benzene ring and the naphthyl system is 70.

Di-μ(1,1)-azido-bis-[(2-{1-[2-(isopropyl-amino)ethyl-imino]eth-yl}phenolato)copper(II)].

In the centrosymmetric binuclear title complex, [Cu(2)(C(13)H(19)N(2)O)(2)(N(3))(2)], the Cu(II) atom adopts an elongated CuON(4) square-based pyramidal coordination geometry, arising from the N,N',O-tridentate ligand and two bridging end-on azide anions. The O atom is in the basal plane, one of the azide N atoms is in the apical site and the Cu⋯Cu separation is 3.2365 (3) Å.

3-Bromo-N'-(2-hydroxy-benzyl-idene)benzohydrazide.

The title mol-ecule, C(14)H(11)BrN(2)O(2), displays a trans configuration about the C=N and C-N bonds. The dihedral angle between the two benzene rings is 18.5 (3)°.
