Efficient catalytic removal of COS and H_(2)S over graphitized 2D micro-meso-macroporous carbons endowed with ample nitrogen sites synthesized via mechanochemical carbonization

Developing a suitable catalyst for the elimination of highly toxic carbonyl sulfide(COS)and hydrogen sulfide(H_(2)S) is of great significance in terms of industrial safety and environmental protection.We demonstrate here the facile synthesis of graphitized 2D micro-meso-macroporous carbons by one-step carbonization of a mixture of urea and glucose at 700–900℃.The as-synthesized graphitized catalysts,designated as 2DNHPC-x(x=urea/glucose mass ratio),are endowed with an ultra-high concentration(12.9–20.2 wt%)of stable and versatile nitrogen sites(e.g.pyrrole and pyridine)which are anchored on the surface via stable covalent bonding.As a result,the 2D-NHPC-x are active in catalytic hydrolysis of COS on pyrrolic N to H_(2)S,and the H_(2)S can be subsequently captured on pyridinic N and converted to elemental sulfur at ambient conditions over the same materials.Among the prepared catalysts,2D-NHPC-x can catalytically hydrolysize 91%of COS to H_(2)S at 30℃,whereas the conversion ratio over the common catalysts g-C_(3)N_(4)and Fe_(2)O_(3)are below 6.0%.Furthermore,these catalysts also exhibit H_(2)S conversion and sulfur selectivity of nearly 100%at 180℃with long-time durability,which is higher than those of the most reported carbonbased catalysts.In contrast,the H_(2)S capacities of activated carbon,ordered mesoporous carbons(OMC)and N-doped OMC are 3.9,1.5 and2.39 mmol g^(-1),respectively.Both the experimental and theoretical results are disclosed that 2D-NHPC-x are superior to the nitrogen-doped porous materials ever applied in simultaneous catalytic elimination of both COS and H_(2)S.

Conduction pathways of resource endowment affecting carbon intensity:Based on interprovincial data in China

By establishing a mathematical model and a basic analytical framework for the impact of resource endowments on carbon intensity,a traditional panel model without spatial panel effects was firstly constructed,a Durbin-Wu-Hausman test was conducted,and the model was set as a fixed-effects model based on the statistical values;secondly,the traditional panel model without spatial effects was estimated,and LM tests and robustness tests were conducted on the regression residuals.The LM test was then used to remove the fixed effect terms by the de-meaning method,and the Matlab 7.0 software was used to estimate the model.The stepwise introduction of variables was used to observe the effect of each variable on economic growth and to analyze the relationship between the magnitude and significance of the regression parameters of each variable.Finally,the path of conduction effect of resource endowment through mediating variable sinfluencing economic growth and carbon emissions,and thus carbon intensity,was constructed.The conclusion is that carbon intensity is inversely proportional to economic growth for a given level of carbon emissions.Therefore,if resource endowment promotes economic growth through mediating variables,it will lead to a decrease in carbon intensity,which is conducive to the achievement of emission reduction targets;conversely,if resource endowment hinders economic growth through mediating variables,it will lead to an increase in carbon intensity,which is not conducive to the achievement of emission reduction targets.

Application of the Concept of“Endowing the Old with the New”in Urban Renewal

The renewal of ancient cities is an important part of the urban renewal work in China.However,there are few studies on the general historical ancient cities at the county level in China,and there is no guidance on the renewal path.Through the practice of the renewal design project of Suining County,Xuzhou City,it makes an exploratory study on the renewal concept and mode.It first interprets the connotation and implementation path of the renewal concept of“endowing the old with the new”.Based on the texture analysis of the ancient city of Suining,it finally determines the design theme that tracing the historical context of the ancient city.Using the renewal techniques such as“extraction-transformationactivation”,through the renewal strategies such as“building new space,shaping new landscape,inheriting new culture and pregnant with new environment”,it realizes the regeneration of urban historical context and meets the needs of residents'modern life,so as to provide reference and guidance for the renovation of general historical ancient cities at the county level in China.

Jade Collection of Emperor Qianlong in the Qing Dynasty

During the reign of emperor Qianlong of the Qing Dynasty,the political rule was relatively stable,the economy continued to develop,and both civil and martial situations flourished.The emperor’s love for jade articles made this period a peak in the development of Chinese jade culture.Based on jade articles of emperor Qianlong collected in the Palace Museum and related documents and archives,this paper tries to explore characteristics of this collection and emperor Qianlong’s collecting methods,then explains that this collection not only has the functions of aesthetics,but also has the meaning of morality,religion and politics.

Research on the Outdoor Activities and Spatial Characteristics of the Elderly in College Communities:Taking a University in Northern China as an Example

In view of the aging population in the country,college communities can better meet the needs of the elderly in the community by developing hardware facilities,environmental resources,and management systems.However,in China,the research on elderly care in colleges is still in its infancy.The paper presents an analysis on the characteristics of the elderly group,outdoor activities,and space characteristics in college communities through the field survey of a university in the north,questionnaire survey and interview with the elderly.Suggestions for optimizing the outdoor activities space of the elderly in college communities are then provided,hoping to provide some reference for relevant research.

Modulating neuronal plasticity with choline

The American psychologist William James once wrote that nervous tissue seems to be endowed with a “very extraordinary” degree of plasticity. To be plastic means to be capable of being molded, receiving shape, or being made to assume a desired form. This can be achieved consequential to changes in the internal and/or external environment. Being plastic, neurons are highly able to amend their structural and functional output, through alteration of their morphology, activation of intracellular signaling cascades, regulation of synaptic density and neurotransmitter release, or a combination of these events.

A General Method of Researching the N-Ordered Fixed Point on a Metric Space with a Graph

In this paper, we propose a new perspective to discuss the N-order fixed point theory of set-valued and single-valued mappings. There are two aspects in our work: we first define a product metric space with a graph for the single-valued mapping whose conversion makes the results and proofs concise and straightforward, and then we propose an SG-contraction definition for set-valued mapping which is more general than some recent contraction’s definition. The results obtained in this paper extend and unify some recent results of other authors. Our method to discuss the N-order fixed point unifies N-order fixed point theory of set-valued and single-valued mappings.

Outdoor Sports Still Has Huge Potential to Develop

In recent years,more and more people have been taking part in outdoor sports,due to the influence of both the COVID-19pandemic and rising health awareness.A variety of new activities,such as elaborate camping by the lake,exploratory cycling in the city and ultimate frisbee on the lawn,have gradually endowed outdoor sports with new features such as strong social interaction,a low participation threshold,as well as leisure and entertainment.
