A planar-integrated optical system(PIOS)represents powerful optical imaging and information processing techniques and is a potential candidate for the realization of a three-dimensional(3D)integrated optoelectronic intelligent system.Coupling the optical wave carrying information into a planar transparent substrate(typically fused silica)is an essential prerequisite for the realization of such a PIOS.Unlike conventional grating couplers for nano-waveguides on the silicon-on-insulator platform,the grating couplers for PIOS enable to obtain a higher design freedom and to achieve much higher coupling efficiency.By combining the rigorous coupled wave algorithm and simulated annealing optimization algorithm,a highefficiency asymmetric double-groove grating coupler is designed for PIOS.It is indicated that,under the condition of the normal incidence of TE polarization,the diffraction efficiency of the-1st order is over 95%,and its average value is 97.3%and 92.8%in the C and C+L bands.The simulation results indicate that this type of grating coupler has good tolerance and is expected to be applied in optical interconnections,waveguide-based augmented reality glasses,and planar-integrated 3D interconnection optical computing systems.

目的分析气道压力释放通气(APRV)和小潮气量通气(LTV)对急性呼吸窘迫综合征(ARDS)炎症的影响,探讨不同机械通气模式对ARDS机械应力相关的作用及机制。方法构建巴马小型成年猪重度ARDS模型,应用LTV与APRV通气模式,进行48 h机械通气治疗,分为空白对照组(control组,n=3)、疾病对照组(ARDS组,n=3)、LTV机械通气组(LTV组,n=4)以及APRV机械通气组(APRV组,n=4)。观察两种通气模式对氧合指数、炎症因子的影响。对肺组织进行高通量测序,并在蛋白层面验证差异基因ITGB4对ARDS机械通气后炎症的影响。使用A549细胞系构建APRV样牵张模型及LTV样牵张模型,进行4 h体外牵张实验,探讨两种牵张模式通过ITGB4对细胞炎症因子分泌的影响。使用小干扰RNA(siRNA)沉默ITGB4表达,比较LTV+siRNA组与APRV+siRNA组ITGB4-FAK-p38-maPK-IL-8通路表达差异。使用p38抑制剂(SB203580)对细胞进行干预,比较LTV+SB203580组和APRV+SB203580组IL-8表达水平的差异。结果重度ARDS造模成功后,通气48 h,APRV组肺泡灌洗液及肺组织中IL-6、IL-8水平显著低于LTV组(P0.05)。转录组高通量测序结果显示,机械通气后细胞外基质受体交互通路及黏着斑信号通路显著富集。在肺组织中,APRV组ITGB4、p-FAK、p-p38蛋白表达水平显著低于LTV组(P0.05)。APRV组的IL-8、ITGB4、p-FAK和p-p38表达水平显著低于LTV组(P0.05)。使用p38抑制剂后,相较于LTV+SB203580组,APRV+SB203580组p-p38磷酸化水平显著下调(P=0.032)。结论APRV机械通气模式通过ITGB4-p38-maPK通路显著改善重度ARDS后炎症因子IL-8的分泌,可能为ARDS治疗提供潜在的干预靶点。

The emergence of non-fullerene acceptors(NFA) offers a promising opportunity to develop high-performance donor/acceptor pairs with high power conversion efficiency,as NFAs offer tunable energy levels,broad absorption and suitable aggregation property.In order to enhance light-harvesting capability of active layers,we choose a wide bandgap polymer PTQ10 as the donor to blend with a narrow bandgap NFAY6 as the acceptor.In comparison with PTQ10:IDIC blend,~130 nm red-shifted absorption spectrum is observed in the PTQ10:Y6 blend,which potentially enhance the short-circuit current density(Jsc) for the PSCs.In addition,the optimal PTQ10:Y6 blend shows higher photoluminescence quenching efficiency and more efficient charge separation,higher charge mobilities,as well as weaker bimolecular recombination over the PTQ10:IDIC blend,which leads to an outstanding power conversion efficiency(PCE) of 16.53%,with a notable Jsc of 26.65 ma cm^-2 and fill factor(FF) of 0.751.

State-of-the-art organic solar cells(OSCs)often require the use of high-boiling point additive or post-treatment such as temperature annealing and solvent vapor annealing to achieve the best efficiency.However,additives are not desirable in largescale industrial printing process,while post-treatment also increases the production cost.In this article,we report highly efficient ternary OSCs based on PM6:BTP-Cl Br1:BTP-2O-4Cl-C12(weight ratio=1:1:0.2),with 16.68%power conversion efficiency(PCE)for as-cast device,relatively close to its annealed counterpart(17.19%).Apart from obvious energy tuning effect and complementary absorption spectra,the improved PCE of ternary device is mainly attributed to improved morphological properties including the more favorable materials miscibility,crystallinity,domain size and vertical phase separation,which endorse suppressed recombination.The result of this work provides understanding and guidance for high-performance as-cast OSCs through the ternary strategy.

Dear Editor,Nanotechnology-based therapeutic strategies have been proven effective in diseases including cancer,infection,inflammation,etc.1 However,the application of nanotechnology is greatly restricted in the treatment of central nervous system(CNS)disorders due to physiological CNS barriers.For example,the blood-brain barrier(BBB)can be the“maginot line”for pharmacologically active molecules,blocking them out of the CNS.

通过两个实验考察了目标保护对象的所有权隐含语及个体的自主选择权对亲环境行为的影响及其潜在心理机制。实验1采用单因素被试间设计,初步探究有/无所有权隐含语对个体亲环境行为的影响及心理所有权的中介作用;实验2引入自主选择权变量,采用2×2被试间设计,进一步检验实验1的发现,同时考察自主选择权是否会调节所有权隐含语的作用以及心理所有权和权力感是否具有链式中介效应。结果发现:所有权隐含语通过心理所有权和权力感的链式中介作用显著影响个体的亲环境行为;自主选择权也影响个体的亲环境行为,却未与所有权隐含语产生显著的交互效应。

Recent advances in non-fullerene acceptors(NFAs),typically Y6,have driven power conversion efficiency(PCE) of single-junction orga nic solar cells(OSCs) over 16%.Mea nwhile,it becomes essential to know how to adopt simple strategies to further improve device performance.In this work,a new A-DA'D-A acceptor derivative,Y19-N3 employing 3-ethylheptyl branched at the 3^(rd)-position instead of 2-ethylhexyl on the pyrroles of Y19 is reported.The selection of an appropriate solvent in casting device is implemented to maximize the photovoltaic performance.PBDB-T:Y19-N3-based OSCs treated with a ternary solvent of CF/CB(1:3,v/v) and 0.8% DIO exhibit the optimal PCE of 13.77% here,with the significantly improved V_(oc)(0.78 V) and FF(0.72) as well as the high J_(sc)(24.46 ma/cm^(2)).Further characterizations indicate that this ternary solvent-treated PBDB-T/Y19-N3 film exhibits the more appropriate morphological features with the highly efficient charge generation and collection as well as the more balanced electron and hole mobilities.This work combines molecular design and device engineering to improve the photovoltaic properties,which is important to the development of OSCs.

为了解决充放电过程中锰酸锂循环性能较差的问题,采用自蔓延燃烧法制备了硅掺杂锰酸锂超细颗粒(LiMn_(1.95)Si_(0.05)O_(4),简称LMSO)。通过X射线衍射光谱、扫描电子显微镜、循环伏安法等方法研究了硅掺杂对锰酸锂晶体结构、微观形貌和电化学性能的影响。结果表明,硅掺杂不会改变锰酸锂尖晶石的结构;锰酸锂的粒径大于0.1μm,而大部分硅掺杂锰酸锂颗粒小于0.1μm。颗粒尺寸减小,缩短了锂离子的扩散路径,提高了材料的电化学性能。LMSO在0.2C倍率下放电比容量高达123.7 ma·h/g,在1C倍率下循环100次后的容量保持率为95%。
