Carbon capture and storage （CCS） technology has been considered as an important method for reducing greenhouse gas emissions and for mitigating global climate change. Three primary options are being considered for large-scale storage of CO2 in subsurface formations： oil and gas reservoirs, deep saline aquifers, and coal beds. There are very many large saline aquifers around the world, which could make a big contribution to mitigating global warming. However, we have much less understanding of saline aquifers than oil and gas reservoirs. Several mechanisms are involved in the storage of CO2 in deep saline aquifers, but the ultimate goal of injection of CO2 into the aquifers containing salt water is to dissolve the CO2 in the water. So it is important to study the solubility trapping and sensitivity factors of CO2 in saline aquifers. This paper presents results of modeling CO2 storage in a saline aquifer using the commercial reservoir simulator ECLIPSE. The objective of this study was to better understand the CO2/brine phase behavior （PVT properties） and quantitatively estimate the most important CO2 storage mechanism in brine-solubility trapping. This would provide a tool by performing theoretical and numerical studies that help to understand the feasibility of CO2 geological storage. A 3-dimensional, 2-phase （water/gas） conceptional reservoir model used finite, homogenous and isothermal formations into which CO2 is injected at a constant rate. The effects of main parameters were studied, including the vertical to horizontal permeability ratio kv/kh, salinity, and residual phase saturations. The results show that the vertical to horizontal permeability ratio has a significant effect on CO2 storage. Moreover, more CO2 dissolves in the brine at lower kv/kh values.

Aromatic liquor breweries produce massive distiller grains containing a high percentage of rice husks that necessitate harmless treatment and resource utilization. These husk-rich distiller grains can be pyrolyzed in the Ni-based catalyst system at a relatively low temperature（480?C） into combustible gas,which is used in liquor distillation, and biochar（BDG） with high mineral nutrients and good surface properties. A 3-year field experiment（2018–2020） was established to understand the effects of BDG on sorghum agronomic performances and greenhouse gas emissions from the soil. The results showed that BDG had higher mineral nutrient（N, P, K, and S） contents, larger cation exchange capacity, and better surface structure than those prepared using the traditional method at 400 and 600?C. Compared with sole chemical fertilizer（CF）, the combination of CF and BDG（CF+BDG） increased sorghum nutrient（N, P, and K） uptake, yield, fertilizer use efficiency, and economic benefit. Cumulative CO2emission from the soil changed little between with and without BDG,indicating the microbial stability of BDG. The effective adsorption of NH3or NH4+by BDG upon N application may reduce N loss through NH3and N2O emissions and increase the efficiency of fertilizer N use. Cumulative CH4emission ranged from 32.45 to 44.86 g ha-1, which could be overlooked as a greenhouse gas in the sorghum field. Moreover, CF+BDG significantly decreased NH3and N2O emissions for the production of each unit of sorghum grains and the CO2emission from the land for the production of a certain amount of sorghum grains. Therefore, CF+BDG exhibited better agronomic and environmental performances in sorghum cultivation.

基于中国居民部门信贷资源集中于消费性贷款与中长期贷款的结构特点,提出当前我国居民部门信贷结构特征可能会抑制家庭创业行为的假说。为验证该假说,利用2017年CHFS数据分析居民部门信贷结构与家庭创业行为之间的关系。研究发现,居民部门信贷期限结构与信贷资金流向结构都会显著地抑制家庭创业行为。理论上,居民部门信贷资源集中于消费性贷款与中长期贷款均有利于提高家庭参与创业活动的积极性,但实际上高房价耗费了大量消费性贷款与中长期贷款,弱化了这两类贷款对创业活动的正向作用。

利用中国家庭追踪调查(CFPS)数据综合刻画中国城镇居民的休闲状况,并实证研究休闲对居民幸福感的影响。研究表明:收入仍是影响当代中国居民幸福感的重要因素,同时相对收入对幸福感的影响明显大于绝对收入。休闲已成为影响居民幸福感的关键变量,且对城镇居民幸福感的增进效应高于收入因素。这一结论即使在考虑休闲变量的内生性问题后仍然成立。增加休闲活动尤其是积极享乐型休闲的时间更能提升中国城镇居民的幸福感。

The limited infiltration and persistence of chimeric antigen receptor(CAR)-T cells is primarily responsible for their treatment deficits in solid tumors. Here, we present a three-dimensional scaffold, inspired by the physiological process of T-cell proliferation in lymph nodes. This scaffold gathers the function of loading,delivery, activation and expansion for CAR-T cells to enhance their therapeutic effects on solid tumors. This porous device is made from poly(lactic-co-glycolic acid) by a microfluidic technique with the modification of T-cell stimulatory signals, including anti-CD3, anti-CD28 antibodies, as well as cytokines. This scaffold fosters a 50-fold CAR-T cell expansion in vitro and a 15-fold cell expansion in vivo. Particularly, it maintains long-lasting expansion of CAR-T cells for up to 30 days in a cervical tumor model and significantly inhibits the tumor growth. This biomimetic delivery strategy provides a versatile platform of cell delivery and activation for CAR-T cells in treating solid tumors.

The study introduces the chemical composition, mechanical properties, physical properties and production processes of the Fe-23Mn-2Al-V austenitic steel. Investigations were made into the formation of cracks in the hot-rolled Fe-23Mn-2Al-V steel plates,with optical microscopy （OM）,scanning electron microscopy （SEM） and energy dispersive spectrum （EDS）. The results have shown that intergranular oxidation in the reheating furnace is the main cause of the cracks on the surface of the hot-rolled steel plates. The surface cracking can be largely avoided by controlling the remaining oxygen content in the reheating furnace and improving continuous casting （ CC ） processes to increase the thickness of fine equiaxed grain layer of the steel slabs.

目前,角膜塑形镜控制近视的有效性已得到验证,但由于其紧贴角膜,可能会对角膜产生一定影响。首先,它会对中央区角膜产生一定的压力,这种压力会对镜片下的泪液流动造成影响,继而影响角膜的氧气和营养物质供给,角膜相对缺氧导致其抵抗力下降。此外,镜片磨损划伤角膜,清洁不彻底导致微生物聚集引起角膜病变,严重者将导致角膜感染。再者,角膜经过塑形后形状会发生一定的改变,厚度会产生变化,进而影响到角膜各层结构之间的作用力。最后,长期的压迫还将导致角膜神经发生改变,敏感性降低。角膜塑形镜对角膜的影响一直是研究的热点,现对此进行总结。

文章利用2019年中国家庭金融调查(CHFS)数据,实证分析国学文化传统对企业家精神的影响。研究发现:(1)整体而言,国学文化传统显著地提高了家庭创业的概率,使用工具变量法检验这一结论依然成立。(2)机制分析表明,国学文化传统通过提高家庭的社会资本而激发其创业活力。(3)异质性分析发现,国学文化传统对企业家精神具有显著的促进作用仅体现在非青年户家庭。(4)进一步分析发现,国学文化传统显著地提高了制造业行业的创业活动,同时也提高了企业的续存能力,但这些积极作用也仅在非青年户家庭样本中显著。这些研究结论表明,在文化多元化的背景之下,要激发青年创业活力,需要大力引导青年汲取中华传统文化的精髓。

本文创新性地将过度自信理论引入住房市场研究,揭示了近年多套房持有率不断上升的内在原因。研究发现,过度自信的投资者会过于相信自身对房地产市场的判断,而忽略公开的房地产市场信息,从而增加住房投资的动机。尽管目前限购政策能有效地抑制住房投资行为,但并不能遏制过度自信行为,从而导致过度自信的投资者涌入非限购区域,推高了非限购区域的住房价格。本文结果显示,由于房地产信息不对称,房地产调控政策效果有限,因此加强房地产市场信息的有效传递不仅能有效地抑制住房投资行为,还有利于住房市场的持续健康发展。
