Article Synopsis
  • Multi-millimeter-tall vertically aligned single-wall carbon nanotube (VA-SWCNT) forests were produced using a specific catalyst (Fe/Gd/AlO), achieving a high growth rate and long catalyst lifespan at elevated temperatures.
  • The addition of Gd significantly extended the catalyst's lifespan by preventing changes in the structure of iron nanoparticles during the carbon nanotube growth process.
  • Electron microscopy revealed that the diameter of SWCNTs remained consistent with Gd present, while it increased without Gd, indicating that Gd helps maintain the stability of the catalyst during growth.

Pork is one of the major food sources of human salmonellosis worldwide, while beef products have been implicated in numerous foodborne outbreaks. As a result, effective interventions to reduce contamination during beef and pork processing are of interest to both regulators and industry. We conducted a rapid systematic review and meta-analysis of literature investigating the efficacy of slaughter and processing interventions to control in beef and pork.

Non-typhoidal Salmonella spp. (hereafter referred to as Salmonella) on beef and pork is an important cause of foodborne illness and death globally. A systematic review of the effectiveness of interventions to reduce Salmonella prevalence or concentration in beef and pork was undertaken.

We developed a simple, rapid, and selective assay method for determination of serum flecainide by using solid phase extraction and reversed phase high performance liquid chromatography (HPLC) equipped with ordinary octadecylsilyl silica (ODS) column and ultraviolet (UV) detector. Serum samples spiked with the internal standard were treated by a disposable C(18)-cartridge to extract flecainide. The flecainide and internal standard were separated on ODS column and were detected with an UV detector set at 298 nm.
