Our findings provide first evidence for the underlying molecular mechanisms of SiO2 ENMs enhancing the rice resistance to planthopper.Appropriate straw and tillage management strategies increase grain yields, and promote atmospheric carbon dioxide (CO2) mitigation through soil organic carbon (SOC) sequestration. However, little is known about economic parameters and carbon footprint (CF, defined as total greenhouse gases emission from the whole life cycle perspective) of intensive wheat (Triticum aestivum L.)-maize (Zea mays L.) double cropping production under different integrated strategies of straw-return and tillage. To quantify the differences of straw-return and tillage integrated strategies in economic parameters and carbon sustainability, a field experiment was established in 2008 in which six integrated strategies were evaluated straw return of both maize and wheat (MR-WR), MR-WR with subsoiling to ~40 cm depth after maize harvest (MS-WR), single straw return of wheat (MN-WR), single straw return of maize (MR-WN), MR-WN with subsoiling to ~40 cm depth after maize harvest (MS-WN) and no straw return (MN-WN). Results showed that the MS-WR had the greatest grain yields of both wheat and maize, gross revenue and economic profit with increases of 45.5%, 35.6%, 26.5%, and 79.7% relative to the MN-WN, respectively. Compared with the initial SOC level, the SOC stock increased by 22.9% under MS-WR, following by MR-WR (16.0%), MS-WN (11.6%), MR-WN (8.0%), MN-WR (5.1%), and MN-WN (-3.8%). The MS-WR reduced the net CF and net CF per economic profit by 35.4% and 64.1% relative to the MN-WN although it elevated the CF by 25.3%. Therefore, adopting the integrated strategies of both maize and wheat straw return with subsoiling to ~40 cm depth after maize harvest represented an economically and C-friendly optimal field management practice for intensive wheat-maize double cropping production in the Guanzhong Plain or other regions with similar environmental conditions in the world.Process ecosystem models are useful tools to provide insight on complex, dynamic ecological systems, and their response to disturbances. The biogeochemical model PnET-BGC was modified and tested using field observations from an experimentally whole-tree harvested northern hardwood watershed (W5) at the Hubbard Brook Experimental Forest (HBEF), New Hampshire, USA. In this study, the confirmed model was used as a heuristic tool to investigate long-term changes in hydrology, biomass accumulation, and soil solution and stream water chemistry for three different watershed cutting intensities (40%, 60%, 80%) and three rotation lengths (30, 60, 90 years) under both constant (current climate) and changing (MIROC5-RCP4.5) future climate scenarios and atmospheric CO2 through the year 2200. For the no future cutting scenario, total ecosystem stored carbon (i.e., sum of aboveground biomass, woody debris and soil) reached a maximum value of 207 t C ha-1 under constant climate but increased to 452 t C ha-1 under changing cto a potential for a deterioration of soil fertility.This paper reports a facile route to prepare bulk zeolites with tunable phase compositions and microstructures by combining hydrothermal treatment and geopolymer precursor technique. Amorphous Na-based geopolymer (NaGP) is transformed into crystalline analcime following hydrothermal treatments. By systematically investigating the effects of hydrothermal conditions on the phase compositions and microstructures of the products, the optimal hydrothermal procedure is screened as treating NaGP in 1 M NaOH solution at 160 °C for 6 h. Furthermore, we achieve control over phase compositions of the resulting bulk zeolites by tailoring the initial Na/K ratio of geopolymer precursors. read more For instance, treating the geopolymer precursor with a Na/K ratio of 9 1 under the optimal hydrothermal procedure leads to the formation of zeolite consisting of analcime and zeolite-P. The as-prepared adsorbents exhibit outstanding adsorption performance for the hazardous elements, among which analcime-zeolite-P shows an adsorption efficiency of 93.3% for Cs+, and NaGP exhibits an adsorption efficiency of 99.6% for Sr2+. Moreover, we reveal the mechanisms underlying the adsorption of Cs+ and Sr2+ in the adsorbents to be chemisorption. Meanwhile, ion exchanges also occur in NaGP and analcime-zeolite-P during Cs+ adsorption. These results render geopolymers and their derived bulk zeolites promising for hazardous elements adsorption.Bio-electrochemical system (BES) emerges as a versatile approach to handling environmental problems with the harvest of sustainable energy and value-added chemicals. To enhance the butyric acid production from rice straw, microbial fuel cell (MFC) and cathodic electro-fermentation (CEF) systems were constructed in this study. Inoculated with the same mixed culture, fermentative butyric acid production efficiency of the two BESs were evaluated with/without neutral red (NR) as electron mediator, respectively. It was found that the butyric acid fermentation efficiency in the MFC system was inefficient. While, the CEF system presented an evident positive effect on butyric acid production. The production and specific yield of butyric acid in the CEF system reached 5.54 g/L and 0.41 g/g, higher than that in the open circuit (OC) system by 17.37% and 28.13%, respectively. Mass percentage of butyric acid in the produced total volatile fatty acids (VFAs) was also increased from 44.74% to 52.76%. The addition of NR had no positive effect on the butyric acid production, due to the low contribution of electric current to the end-products. With the cathode potential of -0.80 V (vs Ag/AgCl), relative abundance of the butyric acid fermenting bacteria (Clostridium cluster IV and cluster XIVa) in the microbial mixture was increased from 20.25% in the OC system to 33.61% in the CEF system. This research work not only presents a novel method for enhancing butyric acid production by rice straw fermentation, but also aids an understanding of the fermentation mechanism in CEF systems.
