Nanofiber PVA‐Based Membranes Incorporating Functionalized Spanish Broom Derivatives for Sustainable Water Purification

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study investigates Spanish broom (Spartium junceum) as a renewable source for electrospun composite membranes in sustainable water purification. MCC and biochar were functionalized with eco‐friendly precursors and nanomaterials (i.e., HNT, β‐CDs) to develop hybrid PVA nanofiber composites.

Crystal structure of 2,3-dimethylmaleic anhydride: continuous chains of electrostatic attraction

Acta Crystallographica Section E: Crystallographic Communications, 2015
In the crystal structure of 2,3-dimethylmaleic anhydride, C6H6O3, the closest non-bonding intermolecular distances, between the carbonyl C and O atoms of neighboring molecules, were measured as 2.9054 (11) and 3.0509 (11) Å, which are well below the sum ...

Novel Zwitterionic Polydopamine Nanofiller‐Reinforced Hybrid Membranes With Superior Antifouling Performance for Wastewater Treatment

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work reports one‐pot synthesized novel zwitterionic polydopamine‐silica (ZSiPDA) nanofillers for fabricating PES hybrid ultrafiltration membranes with enhanced hydrophilicity, permeability, and antifouling performance. The optimized membrane achieved over 91% humic acid removal and showed strong potential for municipal wastewater treatment.

Redox‐Active Bisphosphines Based on a W(II)‐Propargyl Complex Backbone

European Journal of Inorganic Chemistry, EarlyView.
Three bisphosphine ligands based on tungsten(II) propargyl‐type alkyne complexes were synthesized and characterized. The methanolate derivative was used as a metalla‐ligand for the preparation of a binuclear bisphosphine‐κ2‐PdCl2 complex. In both cases, IR spectroelectrochemistry (IR‐SEC) measurements revealed a successive process following oxidation ...

Development of Polyamide 6/Compound by Recycled Rubber Blends Using Graphitized Polyethylene or Polypropylene with Maleic Anhydride as Compatibilizer Agent

Journal of Aerospace Technology and Management, 2013
http://dx.doi.org/10.5028/jatm.v5i2.164 The toughening of polyamide 6 is desirable for many applications and may be obtained by adding a phase to the elastomeric matrix. However, this leads to a loss in its rigidity characteristics.
