Macroeconomic, Political and Institutional Factors of Economic Growth
Publié 2022-07-01Accéder au texte intégralBroad theoretical and empirical literature discusses how economic development is affected by different economic, political, institutional, social, and other factors. The classic macroeconomic growth theory argues that poorer states must have higher rates of economic growth compared to more prosperou...

Nano-lignin filled natural rubber composites: Preparation and characterization
Publié 2013-05-01Accéder au texte intégralThis paper presents a novel strategy to prepare nano-lignin and its composites with natural rubber. The nanolignin was ontained by fabricating colloidal lignin-Poly (diallyldimethylammonium chloride) (PDADMAC) complexes (LPCs) via self-assembly technology. The characteristics of LPCs were investigat...

Synergistically improved thermal conductivity of polyamide-6 with low melting temperature metal and graphite
Publié 2016-08-01Accéder au texte intégralLow melting temperature metal (LMTM)-tin (Sn) was introduced into polyamide-6 (PA6) and PA6/graphite composites respectively to improve the thermal conductivity of PA6 by melt processing (extruding and injection molding). After introducing Sn, the thermal conductivity of PA6/Sn was nearly constant b...

Observational constraints suggest a smaller effective radiative forcing from aerosol–cloud interactions
Publié 2025-07-01Accéder au texte intégral<p>The effective radiative forcing due to aerosol–cloud interactions (ERFaci) is difficult to quantify, leading to large uncertainties in model projections of historical forcing and climate sensitivity. In this study, satellite observations and reanalysis data are used to examine the low-level...

Wear resistance, oil resistance, morphology and vulcanization performances of ethylene-vinyl acetate/acrylonitrile butadiene rubber composites
Publié 2019-12-01Accéder au texte intégralThe composites consisting of ethylene-vinyl acetate rubber (EVM) and acrylonitrile butadiene rubber (NBR) were prepared by two-step blending method, and were reinforced with carbon black (CB) using 1,4-bis(tert-butylperoxyisopropyl) benzene (BIPB) as crosslinking agent. In addition, wear and oil res...

Plane-interface-induced lignin-based nanosheets and its reinforcing effect on styrene-butadiene rubber
Publié 2014-09-01Accéder au texte intégralLignin was viewed as a spherical microgel in aqueous alkali. While spread out in a monolayer or adsorbed on a surface, lignin was made up of flexible, disk-like molecules with approximately the same thickness of 2 nm. According to this principle, we employed the lamina of montmorillonite (MMT) as a...

Reinforcing styrene butadiene rubber with lignin-novolac epoxy resin networks
Publié 2015-01-01Accéder au texte intégralIn this study, lignin-novolac epoxy resin networks were fabricated in the styrene butadiene rubber (SBR) matrix by combination of latex compounding and melt mixing. Firstly, SBR/lignin compounds were co-coagulated by SBR latex and lignin aqueous solution. Then the novolac epoxy resin (F51) was added...

Response of China's Terrestrial Carbon Uptake to Shift in Nitrogen Deposition
Publié 2025-06-01Accéder au texte intégralAbstract China has experienced a shift in nitrogen (N) deposition from an upward trend since 1980s to stabilized since 2001–2005 and decline in recent years due to N management. Global atmospheric chemical transport models tend to underestimate the magnitude of N deposition in China and fail to repr...

Superconducting Nanowire Single-Photon Detector With a System Detection Efficiency Over 80% at 940-nm Wavelength
Publié 2016-01-01Accéder au texte intégralImplementations of quantum information require single-photon detectors (SPDs) with high detection efficiency (DE) at a wavelength of 940 nm, which is a challenge for the available semiconducting SPDs. Superconducting nanowire SPDs (SNSPDs) are capable of detecting visible and near-infrared single ph...
