Characterization of Modified Mechanically Activated Cassava Starch Magnetic Porous Microspheres and Its Adsorption for Cd(II) Ions

Xinling Xie et al.

Summary: The synthesis of cassava starch magnetic porous microspheres (AAM-MSMPMs) was accomplished through graft copolymerization in inverse emulsion. The resulting AAM-MSMPM adsorbent exhibited superparamagnetic behavior and demonstrated a high capacity for the adsorption of Cd(II) ions in aqueous solution. The addition of a porogen resulted in a decrease in particle size, an increase in specific surface area, and an enhancement in adsorption capacity. The adsorption process on the AAM-MSMPM followed Langmuir isothermal and pseudo-second-order kinetic models, with chemisorption as the rate-controlling step. The AAM-MSMPM also displayed excellent stability after multiple reuses.

Electrocatalytic Oxygen Reduction Reaction of Graphene Oxide and Metal-Free Graphene in an Alkaline Medium

Saravanan Nagappan et al.

Summary: Graphene, a two-dimensional material with a large surface area, is widely used in various fields. Recently, there has been increased focus on developing metal-free graphenes doped with heteroatoms as efficient electrocatalysts for oxygen reduction reactions (ORRs). Our study found that graphene prepared from graphene oxide (GO) by pyrolysis under a nitrogen atmosphere at 900 degrees C showed better ORR activity compared to pristine GO. Various pyrolysis conditions were tested, and the results suggest that the ORR electrocatalytic activity of graphene is influenced by these conditions. The prepared graphenes, particularly G100-1B and G100-2B, displayed promising ORR activity for fuel cell and metal-air battery applications.

Preparation and Drug-Loading Properties of Amphoteric Cassava Starch Nanoparticles

Xinling Xie et al.

Summary: Amphoteric cassava starch nanoparticles (CA-CANPs) were prepared using a W/O microemulsion crosslinking method. The particle size of CA-CANPs was studied under different preparation conditions. CA-CANPs with a smooth surface and an average diameter of 252 nm were successfully prepared. The pH-responsive value of CA-CANPs can be regulated by adjusting the nitrogen-phosphorus molar ratio. CA-CANPs showed a high loading rate for paclitaxel (PTX) and a pH-responsive release rate, making them a potential targeted controlled-release carrier for antitumor drugs.

Novel PEPPSI-Type NHC Pd(II) Metallosurfactants on the Base of 1H-Imidazole-4,5-dicarboxylic Acid: Synthesis and Catalysis in Water-Organic Media

Vladimir Burilov et al.

Summary: Carrying out organic reactions in water has attracted much attention. Catalytic reactions in water with metallosurfactants, which have both a metallocenter and the surface activity necessary for solubilizing hydrophobic reagents, are of great demand. In this study, a new approach was proposed to synthesize NHC PEPPSI metallosurfactants by sequentially functionalizing imidazole 4,5-dicarboxylic acid with hydrophilic oligoethylene glycol and lipophilic alkyl fragments. Complexes with different lipophilicity were obtained and their catalytic activity was studied in reduction and Suzuki-Miyaura reactions. A comparison with commercially available PEPPSI-type catalysts designed by Organ was made. It was found that the reduction reaction in an aqueous solution of the metallosurfactant with the tetradecyl lipophilic fragment was three times more active than the commercial PEPPSI complexes, which was attributed to the formation of stable monodisperse aggregates detected by DLS and TEM.

Assessment of the Catalytic Performances of Nanocomposites Materials Based on 13X Zeolite, Calcium Oxide and Metal Zinc Particles in the Residual Biomass Pyrolysis Process

Elena David et al.

Summary: Nanocomposites based on 13X zeolite, calcium oxide, and metal zinc particles were prepared and studied for their catalytic effects on pyrolysis of biomass waste. The introduction of CaO and metal zinc particles into the zeolite structure altered the surface area and pore structure of the nanocomposites, leading to the production of bio-oil and biochar from residual biomass.
