Abstract The introduction and spread of wheat contributed to the transformation tradition millets agriculture in North China. However, when how came be a staple crop China is still unclear. Stable isotope data from some archaeological sites suggested that dietary change C 4 based diet 3 /C mixed occurred during Eastern Zhou Dynasty (770–221 BC ) on Central Plains role each (wheat, rice soybean) human not well understood this key period. Some scholars have argued made biggest contribution...
Abstract The region of Yiluo in North China witnessed the development social complexity Neolithic period and emergence first Chinese state society early Bronze Age. However, agricultural economies Neolithic–Bronze Age periods this its influence on area have not been adequately understood, owing to relative lack evidence from archeobotany, chronology, stable isotope analysis region. Archeobotanical isotopic evidence, together with chronological data Tumen site, reveals that economy composed...
Reconstructing diet can offer an improved understanding toward the origin and evolution of modern humans. However, early humans in East Asia is poorly understood. Starch analysis dental calculus harmless to precious fossil hominins provides most direct evidence plant food sources human dietary records. In this paper, we examined starch grains from Fuyan Cave Daoxian (South China), which were earliest Asia. Our results reveal a hominin made acorns, roots, tubers, grass seeds, other...
The luminescence efficiency of polymer light-emitting diodes is enhanced to more than double by doping ZnO nanorods into the poly-(3,4-ethylenedioxythiophene):poly-(styrenesulphonic acid) (PEDOT:PSS) hole buffer layer. It was demonstrated, means optical and electrical characteristics Raman spectroscopy, that there a certain interaction between thiophene PEDOT nanorods, which decreased amount defect states at interface layer poly(2-methoxy-5-(2'-ethyl-hexyloxy)-1,4-phenylene vinylene)...

Abstract A multicrop agricultural system, including millet, wheat, rice, and soybeans, first emerged in China the Late Longhang period is considered to be one of most important basic foundations underpinning origin development early states China. However, there still a lack studies on specific subsistence strategies humans from Bronze Age, specifically addressing how widespread system was. To explore these questions above, carbon nitrogen isotope analysis human bones Nanwa site (ca 1720–256...
In order to increase the red emission of Eu complex doped in poly(N-vinylcarbazole) (PVK), series molar ratio coprecipitates [TbxEu(1−x)(aspirin)3(phen)∙H2O] (phen=1,10-phenanthroline) were prepared, which Tb3+ ion acts as an energy bridge enhance transfer between ligands and europium ion. The intramolecular from Eu3+ was studied via a time-resolved spectrum. It gave direct evidence two lanthanide ions terbium europium. photoluminescence electroluminescence spectra well performance device...
Two new polyoxometalate-based coordination polymers have been synthesized at different pHs under identical hydrothermal conditions, (Hbib)[Cu2(bib)2(PMo12O40)] (1) and (Hbib)2[Cu(bib) (PMo12O40)]·2H2O (2) (bib = 4-bis(imidazol-1-yl) benzene). Their structures were determined by single crystal X-ray diffraction analyses characterized routine methods. When the pH was adjusted to 2.0 − 2.5, 1 obtained, which exhibits a 1-D rail-like chain. Compound 2 obtained of 2.5 3.2 2-D layer with (44) sql...
Abstract Agricultural yield fluctuations caused by environmental and social factors in ancient China have been well recorded extensive documents; however, comparatively little is known archaeologically. This study revealed the consumption utilization of staple cereal possible famine food Han Dynasty inhabitants Guanzhong area based on archeobotanical evidence, including plant macro‐remains phytoliths uncovered from pottery granaries isotopic evidence human bone collagen Miaojiazhai cemetery....
