Three alkaline earth metal-organic frameworks based on fluorene-containing carboxylates: syntheses, structures and properties

Three metal-organic frameworks, {[Mg_2(MFDA)_2(DMF)_3]·0.5H_2O}_n (1), {[Ca(MFDA)(DMF)(H_2O)]·0.5DMF}_n (2) and [Ca(MFDA)(DMF)_2]_n (3) (DMF=N,N-dimethylformamide) have been synthesized by the solvothermal reactions between the ligand 9,9-dimethylfluorene-2,7-dicarboxylic acid (H_2MFDA) and the corresponding metal salts, respectively. The single crystal X-ray structural analyses reveal that compounds 1–3 display three-dimensional structures based on the M(II)–O–C chains. It is interesting that the MFDA ligands in 1–3 have different dihedral angles between the two carboxylate groups ranging from 9.9(1)° to 41.8(2)°. All of compounds exhibit strong ligand-centered blue emissions under UV lights. Their thermal properties have also been studied.
Rhodanine flanked indacenodithiophene as non-fullerene acceptor for efficient polymer solar cells

A fused-ring electron acceptor IDT-2BR1 based on indacenodithiophene core with hexyl side-chains flanked by benzothiadiazole rhodanine was designed and synthesized. In comparison with its counterpart with hexylphenyl side-chains (IDT-2BR), IDT-2BR1 exhibits higher highest occupied molecular orbital (HOMO) energy but similar lowest unoccupied molecular orbital (LUMO) energy (IDT-2BR1: HOMO=–5.37eV, LUMO=–3.67eV; IDT-2BR: HOMO=–5.52eV, LUMO=–3.69eV), red-shifted absorption and narrower bandgap. IDT-2BR1 has higher electron mobility (2.2′10~(–3) cm~2 V~(–1) s~(–1)) than IDT-2BR (3.4′10~(–4) cm~2 V~(–1) s~(–1)) due to the reduced steric hindrance and ordered molecular packing. Fullerene-free organic solar cells based on PTB7-Th:IDT-2BR1 yield power conversion efficiencies up to 8.7%, higher than that of PTB7-Th:IDT-2BR (7.7%), with a high open circuit voltage of 0.95 V and good device stability.
印度河-恒河平原风成黄土的发现及其意义

风成黄土堆积包含了丰富的古气候演化信息,如中国黄土古环境研究在过去几十年取得了重要进展.目前在印度地区黄土研究大都集中于其北部喜马拉雅山南坡的Kashmir地区,其他地区很少见到风成黄土的报道.通过对印度新德里-安格拉-斋普尔地区平原沉积物的地貌地形及沉积物地层的野外观察,发现其与大部分中国黄土古土壤序列相似,地层之间为过渡的渐变关系,不具有河流冲积物层理,且发育着明显的土壤层次,说明印度河-恒河平原很有可能存在未被识别的风积黄土古土壤序列.为了进一步确定其存在性,本文对位于印度河-恒河平原的一处疑似黄土堆积进行了采样及室内分析,结果表明代表性样品的粒度分布及稀土元素(REE)的配比模式与中国黄土极为相似,同时代表性样品的单颗粒石英扫描电镜(SEM)图像显示出新鲜的贝壳状断口、丰富的撞击圆麻点、机械撞击形成的碟型坑等风尘颗粒具有的特征.此外,环境磁学与岩石磁学实验表明,样品中的主导磁性矿物为亚铁磁性的磁铁矿及磁赤铁矿,可能含有少量的赤铁矿,并且其常温磁学参数与中国黄土具有很好的可比性.综合以上结果,我们认为印度河-恒河平原地区广泛分布着风成黄土堆积,且黄土的存在可能促进了印度农耕的发展,从而推动印度古文明的兴起与繁荣.这也为日后对该地区地层中蕴含的古气候信息解读提供了新的更成熟的研究载体.
Physical mechanism of resistance switching in the co-doped RRAM

The physical mechanism of the resistance switching for RRAM with co-doped defects (Ag and oxygen vacancy) is studied based on the first principle calculations and the simulation tool VASP. The interaction energy,formation energy and density of states of Ag and oxygen vacancy defect (V_O) are calculated. The calculated results reveal that the co-doped system is more stable than the system only doped either Ag or V_O defect and the impurity energy levels in the band gap are contributed by Ag and Vo defects. The obtained partial charge density confirmed further that the clusters are obvious in the direction of Ag to Hf ions, which means that it is Ag but V_O plays a role of conductive paths. For the formation mechanism, the modified electron affinity and the partial charge density difference are calculated. The results show that the ability of electron donors of Ag is stronger than V_O In conclusion, the conductivity of the physical mechanism of resistance switching in the co-doped system mainly depends on the doped Ag.
Perovskite/silicon-based heteroj unction tandem solar cells with 14.8% conversion efficiency via adopting ultrathin Au contact

A rising candidate for upgrading the performance of an established narrow-bandgap solar technology without adding much cost is to construct the tandem solar cells from a crystalline silicon bottom cell and a high open-circuit voltage top cell. Here, we present a four-terminal tandem solar cell architecture consisting of a selffiltered planar architecture perovskite top cell and a silicon heterojunction bottom cell. A transparent ultrathin gold electrode has been used in perovskite solar cells to achieve a semi-transparent device. The transparent ultrathin gold contact could provide a better electrical conductivity and optical reflectance-scattering to maintain the performance of the top cell compared with the traditional metal oxide contact. The four-terminal tandem solar cell yields ari efficiency of 14.8%, with contributions of the top (8.98%) and the bottom cell (5.82%), respectively. We also point out that in terms of optical losses, the intermediate contact of self-filtered tandem architecture is the uppermost problem, which has been addressed in this communication, and the results show that reducing the parasitic light absorption and improving the long wavelength range transmittance without scarifying the electrical properties of the intermediate hole contact layer are the key issues towards further improving the efficiency of this architecture device.
First-principle calculation on mechanical and thermal properties of B2-NiSc with point defects

Using the first-principles plane-wave pseudo-potential method based on density functional theory, the effect of vacancy and anti-position defect on the mechanical and thermal properties of B2-NiSc intermetallics were discussed in detail. Several parameters, such as the shear modulus, bulk modulus, modulus of elasticity, C_(11) — C_(12),the Debye temperature and Poisson's ratio, have been calculated to evaluate the effect of vacancy and anti-position defect on the hardness, ductility and thermal properties of B2-NiSc intermetallics. The results show that V_(Ni), Sc_(Ni),V_(sc) and Ni_(Sc) the four point defects all make the crystal hardness decrease and improve plasticity of B2-NiSc intermetallics. The entropy, enthalpy and free energy of V_(Ni), Sc_(Ni), V_(sc) and Ni_(sc) are monotonously changed as temperature changes. From the perspective of free energy, Ni_(sc) is the most stable, while Sc_(Ni) is the most unstable. Debye temperature of NiSc intermetallics with four different point defects shows V_(Ni), Sc_(Ni), V_(Sc) and Ni_(Sc) the four point defects all reduce the stability of B2-NiSc intermetallics.
The effect of grain orientation on the morphological stability of the organic-inorganic perovskite films under elevated temperature

The fast developing perovskite solar cells shows high efficiency and low cost. However, the stability problem restricts perovskite from commercial use. In this work, we have studied the effect of grain orientation on the morphological stability of perovskite thin films. By tuning the inorganic/organic ratio in the precursor solution,perovskite thin films with both high crystallinity and good morphological stability have been fabricated. The thermal stability of perovskite solar cells based on the optimized films has been tested. The device performance shows no degradation after annealing at 100 °C for 5 h in air. This finding provides general guidelines for the development of thermally stable perovskite solar cells.
Recent progress of dopant-free organic hole-transporting materials in perovskite solar cells

In this perspective,we review the latest developments of conventional perovskite solar cells with a main focus on dopant-free organic hole transporting materials (HTMs). Regarding the rapid progress of perovskite solar cells, stability of devices using dopant-free HTMs are also discussed to help readers understand the challenges and opportunities in high performance and stable perovskite solar cells.

新型硒化亚锗薄膜太阳能电池

无机化合物薄膜太阳能电池如碲化镉(CdTe)和铜铟镓硒(CIGS)等电池,因具有材料用量少、产品轻质可柔性、制备能耗低、弱光和高温发电性能好等优势,从而成为太阳能电池中的热点研究领域之一。然而,因为Cd是剧毒元素,且Te、In资源非常稀缺,这些电池的大范围应用具有一定的局限性。近年来,为了降低成本和解决材料丰度问题,铜锌锡硫硒(CZTSSe)太阳能电池受到了极大的关注。该材料中各元素均属于高丰度低成本的元素,同时具有优异的光学和电学性能,非常适合作为太阳能电池吸收层材料,已取得了12.6%的光电转换效率记录1。然而CZTSSe为五元体系,热力学稳定区间小,生产工艺复杂,产品良率低,同时薄膜组分和晶格缺陷难于精确控制,使得效率的提升空间有限。

Regional path moving horizon tracking controller design for autonomous ground vehicles

A novel regional path tracking description is presented in this manuscript, and the moving horizon control method that is model predictive control (MPC) is proposed to discuss the regional path tracking issue which could avoid colliding road boundary when tracking a more complex road effectively. The feasible region for autonomous ground vehicles (AGVs) running is determined first according to the detected road boundaries. Then, in order to keep the actual trajectory of AGVs in the region and satisfy the safety requirements, MPC method is employed to design the path tracking controller considering actuator and road boundary constraints. In order to verify the effectiveness of the proposed method, experiments based on Hongqi AGV HQ430 are carried out, and the results illustrate that the presented method could be successfully applied to Hongqi AGV vehicle HQ 430.
Organic carbon isotope and pollen evidence for mangrove development and response to human activity in Guangxi (Southwest China) over the last 140 years

Mangrove degradation must reduce carbon sequestration in recent years, thereby aggravating global warming. Thus, short-term impacts of human activity on mangrove ecosystems are cause for concern from local governments and scientists. Mangroves sediments can provide detailed records of mangrove species variation in the last one hundred years, based on detailed 210Pb data. The study traced the history of mangrove development and its response to environmental change over the last 140 years in two mangrove swamps of Guangxi, Southwest China. Average sedimentation rates were calculated to be 0.48 cm/a and 0.56 cm/a in the Yingluo Bay and the Maowei Sea, respectively. Chemical indicators (δ~(13)C_(org) and C:N) were utilized to trace the contribution of mangrove-derived organic matter (MOM) using a ternary mixing model. Simultaneous use of mangrove pollen can help to supplement some of these limitations in diagenetic/overlap of isotopic signatures. We found that vertical distribution of MOM was consistent with mangrove pollen, which could provide similar information for tracing mangrove ecosystems. Therefore, mangrove development was reconstructed and divided into three stages: flourishing, degradation and re-flourishing/re-degradation period. The significant degradation, found in the period of 1968–1998 and 1907–2007 in the Yingluo Bay and the Maowei Sea, respectively, corresponding to a rapid increase of reclamation area and seawall length, rather than climate change as recorded in the region.
Effect of Compound Zhuye Shigao Granule (复方竹叶石膏颗粒) on Acute Radiation-Induced Esophagitis in Cancer Patients: A Randomized Controlled Trial

Objective: To observe the efficacy and safety of the Chinese medicine (CM) Compound Zhuye Shigao Granule (复方竹叶石膏颗粒, CZSG) on acute radiation-induced esophagitis (ARIE) in cancer patients. Methods: In a blinded, randomized, Kangfuxin Solution (康复新液, KFX)-controlled, single-centre clinical trial, 120 patients with lung, esophagus or mediastinal cancer were prospectively enrolled and assigned to the treatment group (60 cases) and control group (60 cases) by the random number table method. All patients received concurrent or sequential radiotherapy (2 Gy per day, 5 times per week, for 4 weeks) and were treated for 4 weeks since the radiation therapy. Patients in the treatment group were given 12 mg CZSG orally, thrice daily, while patients in the control group were given 10 mL KFX orally, thrice daily. The major indicators were observed, including the incidence and grade of esophagitis, time of occurrence and duration. Minor indicators were changes of CM symptoms, weight and Karnofsky Performance Status (KPS) Scale during 4 weeks from the beginning, recorded once a week. Blood routine examination and hepatorenal function were detected at the 2nd and 4th weeks. Results: The incidence and grade of ARIE were significantly decreased in the treatment group compared with the control group (P<0.05). CZSG appeared to significantly delay the time of ARIE occurrence and reduce the duration compared with KFX (P<0.05). The scores of CM symptoms, KPS and weight were improved significantly in the treatment group compared with the control group (P<0.05). There were no blood routine and hepatorenal function abnormal or obvious side-effects in both groups. Hemoglobin was improved and neutrophil and interleukin 6 were decreased in both groups after 4-week treatment compared with before treatment (P<0.05), and there was no significant difference between the two groups (P>0.05). Conclusions: CZSG can decrease the incidence and grade of ARIE, delay the time of occurrence, reduce duration and alleviate the damage of ARIE. It is safe and effective in the prevention and cure of ARIE.
幼儿胸腔镜下左房粘液瘤摘除术后多发大面积脑梗死一例

讨论心脏粘液瘤为良性肿瘤,可发生于心脏各腔。据报道,其发生率为0.11/100 000,其中75%发生于左心房,粘液瘤通常有蒂并有相对狭窄的基底部附着于房间隔,瘤体随心脏收缩和舒张而活动,舒张期可堵塞二尖瓣瓣膜口引起昏厥,甚至心跳骤停。左房粘液瘤呈葡萄状或息肉状,质地疏松,容易脱落引起体循环动脉栓塞。中枢神经系统的肿瘤栓塞,约50%的栓塞事件是由左心房粘液瘤引起的,可能作为首发症状出现,多数发生在大脑左半球,一旦诊断为左房粘液瘤应尽早手术摘除肿瘤。本例患儿年龄小,但左房粘液瘤巨大,随时有可能因栓塞或嵌顿导致死亡,手术是该病唯一且行之有效的治疗手段。
幕上肿瘤患者术中输注甘露醇对血清电解质浓度的影响

甘露醇是目前应用最广泛的降低颅内压的高渗液体。静脉输入高渗甘露醇(20%)溶液后,可在血液和脑实质(脑细胞和细胞外间隙)的液体之间形成渗透浓度差,将脑组织中的水分吸入血液,并通过利尿作用排出体外,从而缩小脑容积和降低颅内压。但是近年来常有报道称甘露醇在临床应用过程中会引起电解质紊乱。Hassan等报道了一例颅内占位患者,术中输注甘露醇1.0 g/kg后15 min,血清K~+浓度升高到6.1 mmol/L,同时心电监测出现T波高尖,经过积极处理后患者心电监测恢复正常。Hirota等也报道了两例术中使用甘露醇后引起电解质紊乱的病例。本研究拟观察颅脑肿瘤手术患者输注常规剂量甘露醇后血清K~+、Na~+的变化规律,以期为甘露醇的临床应用提供参考。

Spatial Variation of Hydraulic Conductivity Categories in a Highly Heterogeneous Aquifer: A Case Study in the North China Plain (NCP)

Compared with research on spatial variation of hydraulic conductivity (K), less effort has been made researching different grades of K value in the North China Plain (NCP). In this study, 3D spatial distribution models of different grades of K were established by considering the effects of clay fraction content and uniformity coefficient (C_u). The K value can be divided into five grades: very low, low, permeable, high, and very high groups. The volume percentages of these clusters were 3.06%, 36.01%, 55.70%, 4.82%, and 0.41% for the first aquifer; 0.016%, 9.56%, 88.25%, 2.16%, and 0.014% for the second aquifer; and 0.04%, 17.74%, 84.21%, 0.001%, and 0.01% for the third aquifer. It is concluded that the high and very high K values are fully affected by burial depth and that the very low, low, and permeable K values are mainly controlled by depositional environment and are partially influenced by burial depth. The burial depth became the main influencing factor only within the same depositional environment, causing the overall K to decrease with depth. The variations of very low, low, permeable, high, and very high categories of K values with depth are described in this study. This can provide useful information for non-technical decision makers to achieve sustainable development of deep groundwater resources.
Assessment of diurnal variation of summer precipitation over the Qilian Mountains based on an hourly merged dataset from 2008 to 2014

To investigate the diurnal variation of summer precipitation in the Qilian Mountains in the northeast Tibetan Plateau, the hourly precipitation amount for this region during the summers of 2008–2014 are analyzed using an hourly merged precipitation product at 0.1°×0.1° resolution. The main results are as follows. (1) The spatial distribution and temporal variation of mean hourly precipitation amount and frequency are generally similar and hourly precipitations in the eastern and middle portions are larger and more frequent than that in the western portion. The high value area of precipitation intensity is obviously different from that of precipitation amount and frequency. (2) The spatial distribution of daytime precipitation is generally similar to that of nighttime precipitation, and the daytime precipitation is heavier than the nighttime precipitation. (3) The change rate of precipitation has a maximum at 20:00 Beijing time, and a minimum at 12:00. The hourly precipitation amount significantly correlated with frequency, especially for the middle and eastern portions.
Comparative evaluation of geological disaster susceptibility using multi-regression methods and spatial accuracy validation

Geological disasters not only cause economic losses and ecological destruction, but also seriously threaten human survival. Selecting an appropriate method to evaluate susceptibility to geological disasters is an important part of geological disaster research. The aims of this study are to explore the accuracy and reliability of multi-regression methods for geological disaster susceptibility evaluation, including Logistic Regression (LR), Spatial Autoregression (SAR), Geographical Weighted Regression (GWR), and Support Vector Regression (SVR), all of which have been widely discussed in the literature. In this study, we selected Yunnan Province of China as the research site and collected data on typical geological disaster events and the associated hazards that occurred within the study area to construct a corresponding index system for geological disaster assessment. Four methods were used to model and evaluate geological disaster susceptibility. The predictive capabilities of the methods were verified using the receiver operating characteristic (ROC) curve and the success rate curve. Lastly, spatial accuracy validation was introduced to improve the results of the evaluation, which was demonstrated by the spatial receiver operating characteristic (SROC) curve and the spatial success rate (SSR) curve. The results suggest that: 1) these methods are all valid with respect to the SROC and SSR curves, and the spatial accuracy validation method improved their modelling results and accuracy, such that the area under the curve (AUC) values of the ROC curves increased by about 3%–13% and the AUC of the success rate curve values increased by 15%–20%; 2) the evaluation accuracies of LR, SAR, GWR, and SVR were 0.8325, 0.8393, 0.8370 and 0.8539, which proved the four statistical regression methods all have good evaluation capability for geological disaster susceptibility evaluation and the evaluation results of SVR are more reasonable than others; 3) according to the evaluation results of SVR, the central-southern Yunnan Province are the highest susceptibility areas and the lowest susceptibility is mainly located in the central and northern parts of the study area.
