A larger nonvolatile bipolar resistive switching memory behaviour fabricated using eggshells
Guangdong Zhou,Bai Sun,Ankun Zhou,Bo Wu,Haishen Huang 한국물리학회 2017 Current Applied Physics Vol.17 No.2
Resistive random access memory (RRAM) devices have emerged as promising candidates for near future nonvolatile information storage. Eggshells, a food waste, have not been focused and recycled sustainably today. Eggshell-based devices have shown a large resistive-switching(RS) memory behaviors with favorable resistance ratio of ~103, larger memory window of ~3.5 V, and high endurance and retention performance. Redox-based Ag filament models involving the formation and rupture of the metallic conduction filaments between top and bottom electrodes are proposed to interpret the large nonvolatile bipolar RS memory behaviors. This discovery provides for the possibility of an environmentally friendly, low-cost and sustainable material application in the next-generation nonvolatile date storage device

Objective: The aim of this study is to identify genomic regions or genes controlling growth traits in pigs. Methods: Using a panel of 54,148 single nucleotide polymorphisms (SNPs), we performed a genome-wide Association (GWA) study in 562 pure Yorshire pigs with four growth traits: average daily gain from 30 kg to 100 kg or 115 kg, and days to 100 kg or 115 kg. Fixed and random model Circulating Probability Unification method was used to identify the associations between 54,148 SNPs and these four traits. SNP annotations were performed through the Sus scrofa data set from Ensembl. Bioinformatics analysis, including gene ontology analysis, pathway analysis and network analysis, was used to identify the candidate genes. Results: We detected 6 significant and 12 suggestive SNPs, and identified 9 candidate genes in close proximity to them (suppressor of glucose by autophagy [SOGA1], R-Spondin 2 [RSPO2], mitogen activated protein kinase kinase 6 [MAP2K6], phospholipase C beta 1 [PLCB1], rho GTPASE activating protein 24 [ARHGAP24], cytoplasmic polyadenylation element binding protein 4 [CPEB4], GLI family zinc finger 2 [GLI2], neuronal tyrosine-phosphorylated phosphoinositide-3-kinase adaptor 2 [NYAP2], and zinc finger protein multitype 2 [ZFPM2]). Gene ontology analysis and literature mining indicated that the candidate genes are involved in bone, muscle, fat, and lung development. Pathway analysis revealed that PLCB1 and MAP2K6 participate in the gonadotropin signaling pathway and suggests that these two genes contribute to growth at the onset of puberty. Conclusion: Our results provide new clues for understanding the genetic mechanisms underlying growth traits, and may help improve these traits in future breeding programs.

By adopting N, N-Dimethylformamide (DMF) atmosphere annealing at room temperature, planar perovskite solar cells with a p-i-n structure of ITO/PEDOT:PSS/Perovskite/PCBM/C60/Al are fabricated by a simple one-step solution process in ambient air with humidity around 50%, and the influence of DMF atmosphere on perovskite solar cells (PSCs) is systematically investigated. Compared to the reference device without DMF reaction, the perovskite films treated by modest DMF annealing show a better distribution and a higher densification, and thus the power conversion efficiency (PCE), short circuit current density (Jsc) and fill factor (FF) are increased by about 17%, 8% and 6%, respectively. This work displays the importance of solvent annealing for perovskite film prepared by the one-step spin-coating method, and possibly provides a simple and cost-effective way to efficiently fabricate PSCs in ambient air.
