Formulation, nanonisation, and characterization of Polyrhachis sp. for enhanced anticancer potential: In vitro studies

  •  23 September 2022

Abstract

Description unavailable

The freeze-dried Polyrhachis sp. (Pol) was loaded into calcium carbonate (CaCO3@Pol) through one step copercipitation method for the first time. The synthesized CaCO3@Pol was characterized using FT-IR, FESEM, DLS, and zeta potential analysis methods. The cytotoxicity evaluation of neat Pol and CaCO3@Pol was performed in vitro on human breast cancer cells (MCF7) and human gastric cancer cells (AGS) through an MTT assay. The release profile of CaCO3@Pol NPs is indicated at two different PH (5.8 and 7.4) in 24h.

Pseudopolymorphism of a luminescent anthracene-pentiptycene π-system: The persistent alkyl-pentiptycene threading mode

  •  22 September 2022

Abstract

Description unavailable

Six pseudopolymorphs of the title compound highlight the primary effect of alkyl-pentiptycene threading interactions and the secondary effect of solvent size in the crystal packing, luminescence properties, and [4+4] photodimerization activity.

High thermoelectric figure of merit in rhombic porous carbon nitride nanoribbons

  •  21 September 2022

Abstract

Description unavailable

By performing density functional theory calculation combined with non-equilibrium Green's function method, the ZT value of the vertical rPCNNR junction is enhanced to 2.1 at 300 K due to the dramatically suppressed thermal conductance by the built-in weak van der Waals interaction and the retaining good electron conductivity contributed by the strong overlapping states in the scattering region.

Fabrication of superhydrophobic CoFe2O4/polyaniline/covalent organic frameworks/cotton fabric membrane and evaluation of its efficiency in separation of olive oil from water

  •  21 September 2022

Abstract

Description unavailable

Ferrite cobalt (CoFe2O4)/polyaniline (PANI)/covalent organic frameworks (COF) composite was prepared.Effective parameters such as composite dose (g), oil/water (O/W) ratio (mL), pH, temperature (oC) on the olive oil from water separation process were studied.The results showed that the coated membrane with a composite dose concentration 0.1 (g), O/W ratio of 100/150 (mL), pH equal to 7 and temperature of 25 (°C) has separation efficiency of 99.99% for 8 s.According to the results, the highest flux obtained is about above 48000 Lm-2h-1.

A Review of Silver Nanoparticles: Research Trends, Global Consumption, Synthesis, Properties, and Future Challenges

  •  732-756
  •  8 June 2017

Abstract

Description unavailable

This paper critically reviews silver nanoparticles (AgNPs) from the perspectives of research trends, global consumptions, synthesis, properties, and future challenges. Generally, the challenges faced are how green technique can be employed to produce other shapes rather than spherical, how the mechanisms and transportations of AgNPs in the environment, and how scaled up synthesis of AgNPs can be achieved. In Malaysia, a proper set of regulations to handle the use of AgNPs should be in place in the near foreseeable future.

Electrochemical Treatment of Heavy Metal-containing Wastewater with the Removal of COD and Heavy Metal Ions

  •  493-502
  •  27 March 2017

Abstract

Description unavailable

During the electrochemical process, organic compounds were formed and pushed to the surface of the aqueous phase due to the generation of gases at the two electrodes. Nevertheless, heavy metal ions were collected at the cathode as hydroxides. The system is simple and can be used several times.

Enhanced photodegradation of methylene blue with alkaline and transition-metal ferrite nanophotocatalysts under direct sun light irradiation

  •  402-408
  •  28 October 2018

Abstract

Description unavailable

Highly efficient metal ferrite nanophotocatalysts are prepared by a simple precipitation method. The excellent degradation efficiency for methylene blue has been attributed to the hydroxyl free radicals. This work shows that these nanophotocatalysts can be used for the degradation of pollutants under direct sunlight irradiation.

Review on Undoped/Doped TiO2 Nanomaterial; Synthesis and Photocatalytic and Antimicrobial Activity

  •  103-116
  •  5 December 2016

Abstract

Description unavailable

This review covers the various synthetic methods of doped and undoped TiO2 nanomaterials, ranging from single-doped and co-doped to multidoped with transition-metal ions, rare earth metal ions, and other metal and nonmetals ions. The effects of doping on the physiochemical properties as well as photocatalytic and antimicrobial activities of TiO2 nanomaterials are reported.
