“…To date, the manufacture of alcohols heavily relies on fossil and biomass carbon sources through different technical routes, [ 1 ] which either have negative environmental impacts or deliver a poor atomic economy while being energy intensive. [ 2 ] For instance, the life‐cycle greenhouse gas emission for producing a liter of bioethanol is ≈1.6 kg CO 2 equivalent. [ 3 ] For fuel ethanol with a global production of ≈104 billion liters per year, [ 4 ] the annual CO 2 emission is more than 170 million metric tons, corresponding to 0.5% of the global annual overall carbon emission.…”

carbon sources through different technical routes, [1] which either have negative environmental impacts or deliver a poor atomic economy while being energy intensive. [2] For instance, the life-cycle greenhouse gas emission for producing a liter of bioethanol is ≈1.6 kg CO 2 equivalent. [3] For fuel ethanol with a global production of ≈104 billion liters per year, [4] the annual CO 2 emission is more than 170 million metric tons, corresponding to 0.5% of the global annual overall carbon emission. [5] New technologies are thus in demand to balance the target of environmental protection and economic development. Electrochemical CO 2 reduction (ECR) driven by renewable energies is a competitive candidate, as it converts CO 2 into liquid products like formate and alcohols with nearly net-zero CO 2 emissions. [6] Nonetheless, the Faradaic efficiency (FE) for CO 2-to-alcohol production generally remains low, typically less than 50%. [7] For instance, Gewirth and co-workers presented a nanoporous Cu-Ag alloy for the enhancement of ECR activity, with an FE toward ethanol of ≈25%. [8] Bell and co-workers reported a Cu-Ag alloy with stain effect, and the total FE of alcohol production was less than 15%. [9] Recently, Sargent and co-workers reported an enhancement of ethanol selectivity in a flow cell system by tuning binding site diversity in an Ag/ Cu catalyst, while the FE for ethanol was still less than 50%. [10] The challenge in developing effective strategies of tuning the energetics of reaction pathways limits the CO 2-to-alcohol selectivity. Based on the theoretical and experimental studies, [11] ethylene (C 2 H 4) generally dominates the C 2+ product distribution, with a theoretical prediction of an alcohol/ethylene ratio of 35:65. [12] However, Calle-Vallejo and Koper reported that ethanol presents a lower free energy position compared to ethylene in the entire reaction route of carbon monoxide (CO) electroreduction to C 2 products. [13] The poor alcohol selectivity has been attributed to the unfavorable adsorption of key intermediates in the ethanol pathway on copper, [13] such as CH 3 CHO* and CH 3 CH 2 O* proved by Chorkendorff and co-workers. [14] Thus, it is rational to hypothesize that an enhanced alcohol selectivity may arise from modulating the adsorption of key intermediates like CH 3 CH 2 O* in the ECR pathways. In addition, it is also well known that Ag component can suppress hydrogen Copper-based catalysts electrochemically convert CO 2 into multicarbon molecules. However, the selectivity toward alcohol products has remained relatively low, due to the lack of catalysts favoring the adsorption of key intermediates in the alcohol pathways. Herein, a Cu 3 Ag 1 electrocatalyst is developed using galvanic replacement of an electrodeposited Cu matrix. The Cu 3 Ag 1 electrocatalyst enables a 63% Faradaic efficiency for CO 2-to-alcohol production and an alcohol partial current density of −25 mA cm −2 at −0.95 V versus reversible hydrogen electrode, corresponding to a 126-fold enhancement in selectivity and 25-...

“…For all other counties and districts in Yuxi City, except Yuanjiang County, the ecological security index and ecological support index changed at the same pace (Fig 8). By further analyzing the Pearson correlation[41]. of the three indexes in SPSS 23.0, the ecological support index and ecological security index are notably positively (P<0.01) related in counties and districts except Yuanjiang County, while in E’shan County, the situation is slightly different by showing an obviously negative correlation (P<0.05).…”

The purpose of this study was to explore the correlations between land use/cover change and cultivated land ecological security in flatland and mountainous areas. Firstly, the spatiotemporal variation characteristics of land use/cover change are described in conjunction with ArcGIS10.5 software based on remote sensing images of 2005 and 2015. Then, by establishing a pressure-support framework as an assessment indicator system and developing an improved BP neural network model via a genetic algorithm with the help of MATLAB2016a, the spatiotemporal dynamic changes of cultivated land ecological security in Yuxi City from 2005 to 2015 are evaluated. The results showed that the transformation of farmland area accounted for a large proportion of increased constructive land and land use/cover spatial variations were significantly different among counties, which manifested the changes in farmland and the construction land in flatland areas but also facilitated a mutual transformation of forest and grass in mountainous areas. Moreover, ecological security status presented a clear difference among counties due to their different land use/cover changes. The ecological security state of the flatland expressed a higher ecological pressure and lower ecological support, so the security grade was IV. Otherwise, the ecological security was superior and the security grade was level II or I in the mountainous areas. Thus, protection strategies for ecological security should be differentiated in the flatland areas and mountainous areas due to their different ecological security status brought by land use/cover change.

“…In order to investigate the stability of developed communities, we tested their resilience towards the moderate toxic compound toluene, as an example of recurrent soil pollution with organic solvents (40). To this end, we split the stabilized ten SynCom replicates in two groups of five after the fifth growth cycle; one series of which was exposed to toluene vapor during the next one-week cycle, the other cultured as before.…”

Microbiomes are typically characterised by high species diversity but it is poorly understood how such system-level complexity can be generated and propagated. Here, we used soils as a relevant model to study microbiome development. Despite inherent stochastic variation in manipulating species-rich communities, both laboratory-mixed medium complexity (21 soil bacterial isolates in equal proportions) and high-diversity natural top-soil communities followed highly reproducible succession paths, maintaining distinct soil microbiome signatures. Development trajectories and compositional states were different for communities propagated in soils than in liquid suspension. Microbiome states were maintained over multiple renewed growth cycles but could be diverged by short-term pollutant exposure. The different but robust trajectories demonstrated that deterministic taxa-inherent characteristics underlie reproducible development and self-organized complexity of soil microbiomes within their environmental boundary conditions. Our findings also have direct implications for potential strategies to achieve controlled restoration of desertified land.TEASERSpecies-rich soil microbiomes grow and propagate reproducibly despite inherent stochastic complexity, paving the way for soil restoration.
