Article Synopsis
- Biomarkers can indicate diseases before symptoms appear, and detecting these early is crucial for treatment.
- Researchers developed a highly sensitive interdigitated sensor using polyvinyl alcohol nanofibers and carbon nanotubes to detect C-reactive protein, an inflammatory biomarker.
- The sensor achieved a detection limit of 100 ng/mL to 1 fg/mL, and showed significant changes in electrochemical impedance, which improved its sensitivity through enhanced binding and charge transfer characteristics.
Traces (ppm to ppb level) of airborne contaminants such as CrO(OH) and SO irreversibly degrade the electrochemical activity of air electrodes in high-temperature electrochemical devices such as solid oxide fuel cells by retarding oxygen reduction reactions. The use of getter has been proposed as a cost-effective strategy to mitigate the electrode poisoning. However, owing to the harsh operating conditions (i.

Methods: Population, Intervention, Control, Outcome, Study Design (PICOS), Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), and Meta-Analyses of Observational Studies in Epidemiology (MOOSE) methods were used to identify studies on PubMed (from 1985 to 2018), including patients with American Joint Committee on Cancer (AJCC) T1-T2N0 basal cell carcinomas and squamous cell carcinomas and ≥10 months follow-up who received CE, MMS, EBRT, or BT. The primary endpoint was cosmesis, classified as "good," "fair," or "poor.
Degradation of cathode in solid oxide fuel cells (SOFC) remains a major concern for the long-term performance stability and operational reliability. The presence of gas phase chromium species in air has demonstrated significant cathode performance degradation during long-term exposure due to unwanted compound formation at the cathode and electrolyte interface which retards the oxygen reduction reaction (ORR). We have demonstrated a novel method to mitigate the cathode degradation using chromium getters which capture the gas phase chromium species before it is ingested in the cathode chamber.
