This study applied an electro-Fenton process using chemically modified activated carbon derived from rubber seed shells loaded with α-FeOOH (RSCF) as catalyst to remove tetracycline residues from aquatic environment. Catalyst characteristics were evaluated using SEM, EDS, XRD, and XPS, showing successful insertion of iron onto the activated carbon. The effects of the parameters were investigated, and the highest treatment efficiency was achieved at pH of 3, Fe: HO ratio (w/w) of 500:1, catalyst dose of 1 g/L, initial TCH concentration of 100 mg/L, and electric current of 150 mA, with more than 90% of TCH being eliminated within 30 min.

Article Synopsis
  • Sugarcane bagasse is a common agricultural waste in Vietnam, rich in cellulose, making it a sustainable material for creating cellulose carbon aerogels.
  • The study utilized this waste to synthesize cellulose aerogels using various crosslinking agents, confirming their structure and properties through multiple analytical methods.
  • Among the aerogels created, the cellulose-sodium alginate version exhibited low density, high porosity, and effective salt adsorption, demonstrating strong potential for use in desalination applications with lasting performance.

Casein Kinase 1 (CK1) is a family of serine/threonine protein kinases that play a crucial role in various cellular processes, including cell proliferation, survival, and metabolism. The dysregulation of CK1 expression has been implicated in the development and progression of several types of cancer, making it an attractive target for anticancer therapy. In this review, we provide an overview of the current strategies employed to target CK1 for cancer therapy and discuss the future perspectives in this field.

Six compounds were isolated from the ethyl acetate extract of the stems of , including miliutine A acid (), a new cyclofarnesane sesquiterpenoid; miliutine B methyl ester (), a cyclofarnesane sesquiterpenoid which was determined the absolute configuration for the first time and four known phenol derivatives (-). NMR spectroscopic and mass spectrometry were used for identifying relative configurations. The assignments of the absolute configurations were determined based on Electronic Circular Dichroism (ECD) and NOESY spectra analysis.

With the acceleration of global industrialization, organic pollutants have become a threat to ecological safety and human health. This work prepared TiO/rice husk biochar (TiO/BC) for removal of bisphenol A (BA) micropollutant in wastewater. Experiment results revealed a low BA removal efficiency by TiO/BC was observed at 34.

Titanium oxide-based photocatalysts (TOBPs) have been widely utilized as potential materials for numerous applications, such as wastewater treatment, water-splitting reactions, carbon dioxide (CO) reduction and photosynthesis. However, the large bandgap of intrinsic TiO limits their absorption toward visible light, which is the central part of the solar spectrum, resulting in low photocatalytic activities under sunlight. To overcome this obstacle, several strategies, such as doping with either metal or non-metal elements or combining with other compounds, are efficient ways to reduce the bandgap of TiO, leading to effectively extending their absorption toward the visible region and increasing their catalytic performance.

For the fabrication of a peelable coating material that decomposes methyl paraoxone (MPO), a nerve agent simulant, self-crosslinkable waterborne polyurethanes (PUs) containing silane groups at the ends and a metal organic framework (UiO-66) were synthesized. UiO-66 dispersed PU solutions for spray coating were prepared by controlling the amount of silane in PU and the content of UiO-66. PUs with a large amount of silane (more than 7.
