In this work, we report the fabrication
and performance of supercapacitors
made from carbonized peanut shells, which are renewable materials
with a huge annual yield and are usually discarded directly by people.
With proper treatment, peanut shells could be used for many applications.
Herein, we demonstrate that the peanut shells treated with carbonization
and activation processes not only possess an extremely high surface
area but also provide a hierarchical structure for energy storage.
The performance of the electrode can be further improved by nitrogen
doping and adding graphene oxide to the electrode. The electrode shows
a specific capacitance of 289.4 F/g, which can be maintained at an
acceptable level even at a high scanning rate. In addition, a good
capacitance retention of 92.8% after 5000 test cycles demonstrates
that the electrode possesses an excellent electrochemical property.
Background/Aim: Interleukin-16 has been reported to exhibit tumoricidal effects, however, the contribution of IL-16 genotypes to lung cancer is still largely unrevealed. This study aimed at investigating whether IL-16 genotypes contribute to lung cancer susceptibility. Materials and Methods: IL-16 rs4778889, rs11556218, and rs4072111 genotypic characteristics were determined among 358 lung cancer patients and 716 controls via the polymerase chain reaction-based restriction fragment length polymorphism (PCR-RFLP) methodology. Results: The highlight finding is that the distributions of genotypic (p=8.6E-10) and allelic (p=0.0001) frequencies of IL-16 rs11556218 was significantly different between cases and controls. In detail, the frequencies of IL-16 rs11556218 heterozygous variant TG and homozygous variant GG were 36.6 and 7.3% among the lung cancer patients, significantly higher than those among the controls (22.5% and 2.6%). On the other way, no difference was observed regarding IL-16 rs4778889 or IL-16 rs4072111. Conclusion: The present study indicates IL-16 rs11556218 G allele is significantly associated with increased Taiwan lung cancer risk.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
