One important subject in the field of all-polymer solar cells (all-PSCs) is the exploration of electron-deficient building blocks with optimized physicochemical properties to promote the performance of polymer acceptors. Here, two ladder-type heteroheptacene-containing small-molecule acceptors with branched 2-octyldodecyl or 2-hexyldecyl side-chains are synthesized and polymerized with the thiophene co-monomer to afford polymer acceptors (PW-OD and PW-HD) with strong near-infrared absorption. Experimental results reveal that the alkyl chain length has a large impact on the molecular packing behavior of the resulting polymers, which in turn affects their light-absorbing and charge transport properties, and thus the photovoltaic performance of the final devices. When blended with the polymer donor PM6, PW-HD-based all-PSCs deliver a higher power conversion efficiency (PCE) of 9.12% compared to the PCE of 6.47% for the PW-OD-based all-PSCs, mainly due to its more ordered inter-chain packing and more favorable blend morphology. This work provides a promising building block for the development of high-performance narrow-bandgap polymer acceptors and highlights the importance of side-chain substitution in optimizing the photovoltaic performance of polymer acceptors.

起源于中世纪的巡回法庭,在近代早期成为英国司法组织的重要组成部分,获得了巡回审判的司法垄断权。近代早期巡回法庭的组织结构日趋完善,司法职能与行政职能也获得极大发展。巡回法官由职业法律者担任,通常每年两次到巡回区审理刑事与民事诉讼。巡回法官作为中央政府的代理人,是中央与地方的联系枢纽。巡回法官不仅传达中央政府的政策与法令,而且监督以治安法官为权力中心的地方政府,并指导业余的治安法官审理司法案件。巡回法官积极参与地方治理,为国家治理的发展提供强劲动力。

N6-methyladenosine(m^(6)A), the most prevalent and conserved RNA modification in eukaryotic cells, profoundly influences virtually all aspects of mRNA metabolism. mRNA plays crucial roles in neural stem cell genesis and neural regeneration, where it is highly concentrated and actively involved in these processes. Changes in m^(6)A modification levels and the expression levels of related enzymatic proteins can lead to neurological dysfunction and contribute to the development of neurological diseases. Furthermore, the proliferation and differentiation of neural stem cells, as well as nerve regeneration, are intimately linked to memory function and neurodegenerative diseases. This paper presents a comprehensive review of the roles of m^(6)A in neural stem cell proliferation, differentiation, and self-renewal, as well as its implications in memory and neurodegenerative diseases. m^(6)A has demonstrated divergent effects on the proliferation and differentiation of neural stem cells. These observed contradictions may arise from the time-specific nature of m^(6)A and its differential impact on neural stem cells across various stages of development. Similarly, the diverse effects of m^(6)A on distinct types of memory could be attributed to the involvement of specific brain regions in memory formation and recall. Inconsistencies in m^(6)A levels across different models of neurodegenerative disease, particularly Alzheimer's disease and Parkinson's disease, suggest that these disparities are linked to variations in the affected brain regions. Notably, the opposing changes in m^(6)A levels observed in Parkinson's disease models exposed to manganese compared to normal Parkinson's disease models further underscore the complexity of m^(6)A's role in neurodegenerative processes. The roles of m^(6)A in neural stem cell proliferation, differentiation, and self-renewal, and its implications in memory and neurodegenerative diseases, appear contradictory. These inconsistencies may be a

为了探讨玉米秸秆还田条件下不同耕作方式及施氮量对土壤耕性及冬小麦产量的影响,于2012年10月至2015年6月连续3个小麦生长季进行了田间定位试验。设3种耕作方式,分别为连续3年旋耕秸秆不还田、连续3年旋耕秸秆还田和前2年旋耕秸秆还田第3年深耕秸秆还田,每种耕作方式下均设4个施氮水平,施氮量依次为165、225、300和360 kg hm^(-2)。与旋耕相比,深耕促进还田玉米秸秆的腐解,且增施氮肥能提高秸秆腐解速度,从而提高耕层土壤的有机质含量。秸秆不还田条件下,连续旋耕降低了0~30 cm土层的有机质含量,结果土壤容重增大,孔隙度降低,且增施氮肥不利于土壤物理性状的改善;秸秆还田条件下,连续旋耕提高了0~10 cm土层有机质含量,土壤容重随之减小,孔隙度增加;秸秆还田条件下,连续2年旋耕1年深耕比连续旋耕增加了10~30 cm土层有机质含量,显著降低了0~20 cm土层容重,增加了0~20 cm土层的总孔隙度和10~30 cm土层的毛管孔隙度。连续3年旋耕造成冬小麦减产,尤其是秸秆不还田处理,第3年产量较第1年下降5.0%~8.7%;旋耕秸秆还田较旋耕不还田平均增产7.3%~8.9%,但在第3年产量下滑;而旋耕还田后适时深耕还田比连续旋耕还田平均增加有效穗数14.5%,增加穗粒数5.7%,产量平均提高7.6%。在玉米秸秆还田条件下,增施氮肥有助于改善土壤理化性质,但225、300和360 kg hm^(-2)氮肥水平的产量无显著差异。本研究结果表明,山东省小麦高产高效栽培技术宜采取秸秆还田、2年旋耕1年深耕、配施纯氮225 kg hm-2的种植模式。
