NASICON-Structured NaTi_2(PO_4)_3 for Sustainable Energy Storage

Several emerging energy storage technologies and systems have been demonstrated that feature low cost,high rate capability,and durability for potential use in large-scale grid and high-power applications.Owing to its outstanding ion conductivity,ultrafast Na-ion insertion kinetics,excellent structural stability,and large theoretical capacity,the sodium superionic conductor (NASICON)-structured insertion material NaTi_2(PO_4)_3 (NTP) has attracted considerable attention as the optimal electrode material for sodium-ion batteries (SIBs) and Na-ion hybrid capacitors (NHCs).On the basis of recent studies,NaTi_2(PO_4)_3 has raised the rate capabilities,cycling stability,and mass loading of rechargeable SIBs and NHCs to commercially acceptable levels.In this comprehensive review,starting with the structures and electrochemical properties of NTP,we present recent progress in the application of NTP to SIBs,including non-aqueous batteries,aqueous batteries,aqueous batteries with desalination,and sodium-ion hybrid capacitors.After a thorough discussion of the unique NASICON structure of NTP,various strategies for improving the performance of NTP electrode have been presented and summarized in detail.Further,the major challenges and perspectives regarding the prospects for the use of NTP-based electrodes in energy storage systems have also been summarized to offer a guideline for further improving the performance of NTP-based electrodes.

An integrated system has been provided with a-Si/H solar cells as energy conversion device,NiCo_2O_4 battery-supercapacitor hybrid (BSH) as energy storage device,and light emitting diodes (LEDs) as energy utilization device.By designing three-dimensional hierarchical NiCo_2O_4 arrays as faradic electrode,with capacitive electrode of active carbon (AC),BSHs were assembled with energy density of 16.6 Wh kg-1,power density of 7285 W kg-1,long-term stability with 100% retention after 15,000 cycles,and rather low self-discharge.The NiCo_2O_4//AC BSH was charged to 1.6 V in 1 s by solar cells and acted as reliable sources for powering LEDs.The integrated system is rational for operation,having an overall efficiency of 8.1% with storage efficiency of 74.24%.The integrated system demonstrates a stable solar power conversion,outstanding energy storage behavior,and reliable light emitting.Our study offers a precious strategy to design a self-driven integrated system for highly efficient energy utilization.
Stereolithographic 3D Printing-Based Hierarchically Cellular Lattices for High-Performance Quasi-Solid Supercapacitor

3D printing-based supercapacitors have been extensively explored,yet the rigid rheological requirement for corresponding ink preparation significantly limits the manufacturing of true 3D architecture in achieving superior energy storage.We proposed the stereolithographic technique to fabricate the metallic composite lattices with octet-truss arrangement by using electroless plating and engineering the 3D hierarchically porous graphene onto the scaffolds to build the hierarchically cellular lattices in quasi-solid supercapacitor application.The supercapacitor device that is composed of composite lattices span several pore size orders from nm to mm holds promising behavior on the areal capacitance (57.75 mF cm~(–2)),rate capability (70% retention,2-40 mA cm~(–2)),and long lifespan (96% after 5000 cycles),as well as superior energy density of 0.008 mWh cm~(–2),which are comparable to the state-of-the-art carbon-based supercapacitor.By synergistically combining this facile stereolithographic 3D printing technology with the hierarchically porous graphene architecture,we provide a novel route of manufacturing energy storage device as well as new insight into building other high-performance functional electronics.
Spiral Steel Wire Based Fiber-Shaped Stretchable and Tailorable Triboelectric Nanogenerator for Wearable Power Source and Active Gesture Sensor

Continuous deforming always leads to the performance degradation of a flexible triboelectric nanogenerator due to the Young’s modulus mismatch of different functional layers.In this work,we fabricated a fiber-shaped stretchable and tailorable triboelectric nanogenerator (FST-TENG) based on the geometric construction of a steel wire as electrode and ingenious selection of silicone rubber as triboelectric layer.Owing to the great robustness and continuous conductivity,the FST-TENGs demonstrate high stability,stretchability,and even tailorability.For a single device with~6 cm in length and~3 mm in diameter,the open-circuit voltage of~59.7 V,transferred charge of~23.7 nC,short-circuit current of~2.67 μA and average power of~2.13 μW can be obtained at 2.5 Hz.By knitting several FST-TENGs to be a fabric or a bracelet,it enables to harvest human motion energy and then to drive a wearable electronic device.Finally,it can also be woven on dorsum of glove to monitor the movements of gesture,which can recognize every single finger,different bending angle,and numbers of bent finger by analyzing voltage signals.
Non-contrast CT image characteristics on admission predict the 3-month outcome of cerebral venous sinus thrombosis: an observational study in a single institution

Background: Various computed tomography (CT) appearances of cerebral venous sinus thrombosis (CVST) were associated with different prognosis and the patients with large intracranial hematoma will have adverse outcomes, but no in-depth study of non-contrast CT image appearances was carried out. We aimed to test the hypothesis that non-contrast CT image characteristics on admission are associated with and predict the outcome of CVST at 3months. Methods: Three hundred and six patients with CVST between 2008 and 2017 were collected. Age, sex, onset of CVST(acute, subacute, or chronic), etiology, clinical manifestations, midline shift, occluded venous sinus, location of infarction, non-contrast CT image characteristics, and the 3-month outcome were recorded. In addition, we established a non-contrast CT image-based classification and grading system to test the hypothesis; the CVST patients were classified into four grades (namely non-contrast CT image-based classification): grade I, no obvious abnormality; grade II, simple vein infarction without hemorrhage or with subarachnoid hemorrhage; grade III, cerebral venous infarction with subarachnoid hemorrhage; and grade IV, cerebral vein infarction with hematoma. All enrolled patients had received subcutaneous injections of low molecular weight heparin subcutaneous injection for 14 days. Thereafter, oral anticoagulant therapy with warfarin was continued. Patients with epilepsy were given antiepileptic drugs, and patients with cerebral herniation received decompressive craniotomy. Results: Our observational findings revealed that midline shift (> 5mm), location of lesion (frontal lobe and temporal lobe), and cerebral venous infarction with subarachnoid or hematoma (grade III and IV) were associated with 3-month poor outcome (p < 0.05); the respective increased risks were 12.730 [risk ratio (RR) 12.730, 95 %confidence interval (CI) 1.680–96.490, p = 0.014], 46.538 (RR 146.538, 95 %CI 6.222–348.079, p = 0.000), 32.549 (RR 32.549, 95 %CI 2.180–486.104, p = 0.012), 37.725 (RR 37.725, 95 %CI 2.051–693.778, p = 0.015), and 93.164-fold (RR 93.164, 95 %CI 11.137–779.328, p = 0.000). However, seizure, hemiplegia, location of occluded venous sinus (super sagittal sinus and deep venous systems), location of infarction (parietal lobe), and non-contrast CT image-based classification (I) were not correlated with the adverse outcome (p > 0.05). Conclusions: Our findings suggested that non-contrast CT image characteristics on admission were associated with and predict the 3-month outcome of CVST. However, the ultimate conclusions need to be confirmed by a large sample of CVST patients at multiple institutions.
Extremely Active Tropical Cyclone Activities over the Western North Pacific and South China Sea in Summer 2018:Joint Effects of Decaying La Nina and Intraseasonal Oscillation

In summer 2018,a total of 18 tropical cyclones (TCs) formed in the western North Pacific (WNP) and South China Sea (SCS),among which 8 TCs landed in China,ranking respectively the second and the first highest since 1951.Most of these TCs travelled northwest to northward,bringing in heavy rainfall and strong winds in eastern China and Japan.The present study investigates the impacts of decaying La Nina and intraseasonal oscillation (ISO) on the extremely active TCs over the WNP and SCS in summer 2018 by use of correlation and composite analyses.It is found that the La Nina episode from October 2017 to March 2018 led to above-normal sea surface temperature (SST) over central-western Pacific,lower sea level pressure and 500-hPa geopotential height over WNP,and abnormally strong convective activities over the western Pacific in summer 2018.These preceding oceanic thermal conditions and their effects on circulation anomalies are favorable to TC genesis in summer.Detailed examination reveals that the monsoon trough was located further north and east,inducing more TCs in northern and eastern WNP;and the more eastward WNP subtropical high as well as the significant wave train with a “– + – +” height anomaly pattern over the midlatitude Eurasia-North Pacific region facilitated the northwest to northward TC tracks.Further analyses reveal that two successively active periods of Madden-Julian Oscillation (MJO) occurred in summer 2018 and the boreal summer intraseasonal oscillation (BSISO) was also active over WNP,propagating northward significantly,corresponding to the more northward TC tracks.The MJO was stagnant over the Maritime Continent to western Pacific,leading to notably enhanced convection in the lower troposphere and divergence in the upper troposphere,conducive to TC occurrences.In a word,the extremely active TC activities over the WNP and SCS in summer 2018 are closely linked with the decaying La Nina,and the MJO and BSISO;their joint effects result in increased TC occurrences and the TC tracks being shifted more northwest to northward than normal.
Performance of CAMS-CSM in Simulating the Shortwave Cloud Radiative Effect over Global Stratus Cloud Regions:Baseline Evaluation and Sensitivity Test

The ability of climate models to correctly reproduce clouds and the radiative effects of clouds is vitally important in climate simulations and projections.In this study,simulations of the shortwave cloud radiative effect (SWCRE) using the Chinese Academy of Meteorological Sciences Climate System Model (CAMS-CSM) are evaluated.The relationships between SWCRE and dynamic-thermodynamic regimes are examined to understand whether the model can simulate realistic processes that are responsible for the generation and maintenance of stratus clouds.Over eastern China,CAMS-CSM well simulates the SWCRE climatological state and stratus cloud distribution.The model captures the strong dependence of SWCRE on the dynamic conditions.Over the marine boundary layer regions,the simulated SWCRE magnitude is weaker than that in the observations due to the lack of low-level stratus clouds in the model.The model fails to simulate the close relationship between SWCRE and local stability over these regions.A sensitivity numerical experiment using a specifically designed parameterization scheme for the stratocumulus cloud cover confirms this assertion.Parameterization schemes that directly depict the relationship between the stratus cloud amount and stability are beneficial for improving the model performance.
Why Is the East Asian Summer Monsoon Extremely Strong in 2018? —Collaborative Effects of SST and Snow Cover Anomalies

In 2018,summer precipitation was above normal in North and Northwest China and below normal around the Yangtze River valley,due to an extremely strong East Asian summer monsoon (EASM).The atmospheric circulation anomalies in East Asia and key external forcing factors that influence the EASM in 2018 are explored in this paper.The results show that there existed an anomalous cyclonic circulation near the Philippines,while the western Pacific subtropical high was located more northward than its normal position.In the mid-high latitudes,a negative geopotential height anomaly center was found near the Ural Mountains,suppressing the blocking activity.Under such a circulation pattern,precipitation near the Yangtze River valley decreased because local divergence and subsidence intensified,whereas precipitation in northern China increased due to large amounts of water vapor transport by anomalously strong southerly winds.Further analyses reveal that the strong EASM circulation in 2018 might result from the joint influences of several external forcing factors.The weak La Nina event that started from October 2017,the positive North Atlantic Tripolar mode (NAT) in spring 2018,and the reduced snow cover over the Tibetan Plateau in winter 2017/18 all collaboratively contributed to formation of the cyclonic circulation anomaly near the Philippines,leading to the extremely strong EASM.Especially,the positive NAT and the reduced Tibetan snow cover may have caused the negative geopotential height anomaly near the Ural Mountains,in favor of a strong EASM.The above external factors and their reinforcing impacts on the EASM are further verified by two groups of similar historical cases.
Preface to the special issue on Energy Storage and Conversion

Energy crisis and environmental pollution owing to the rapid consume of fossil fuel have become the two major challenges faced by human beings. Using the new energy, such as solar and wind energy to replace the fossil fuel, is a promising strategy to address the above issues. However, how to implement such new energy is still a big challenge. Developing chemical energy storage and conversion devices with high performance, low cost, long lifespan and high safety for wide applications has attracted tremendous attentions. The energy storage devices candidates include Li-ion batteries, Li-S batteries, Na-ion batteries, fuel cell, redox flow batteries and etc. In recent years, significant progresses have been made spanning from the fundamental studies to application-oriented prototypes in the field of energy storage and conversion. For this reason, we organize this special issue on “energy storage and conversion” in Journal of Central South University to show the latest advances in this field.
A comparative study between haemocoagulase and adrenaline in type 1 tympanoplasty

Introduction: Haemostasis is a critical component of ear surgeries, which can be achieved by topical methods including simple manual pressure with gauze or cotton balls soaked with adrenaline, administration of haemostatic agents or vasoconstrictive materials. Objective: To compare efficacy of haemocoagulase and adrenaline in attaining middle ear haemostasis in type - 1 tympanoplasty with or without cortical mastoidectomy. To study the effect of haemocoagulase in middle ear. Materials and method: This is a prospective comparative study conducted in a tertiary care hospital from January 2013 to June 2014. Patients undergoing type 1 tympanoplasty with or without cortical mastoidectomy were divided into two groups. In group A(50 cases), cotton balls soaked in 2ml Haemocoagulase was used and in group B(50 cases) cotton balls soaked in 2 ml Adrenaline(1:1000 dilution) was used for middle ear haemostasis. The efficacy of haemocoagulase and adrenaline was compared. Results: The mean number of cotton balls used in haemocoagulase group in cases with congested middle ear mucosa was more than those used in the adrenaline group. Duration of surgery was more in haemocoagulase group(65 min) with congested mucosa, compared to adrenaline group(50 min). The mean blood pressure was significantly higher in adrenaline group compared to haemocoagulase group. Postoperative hearing improvement in both groups showed no significant difference with p value 0.694. Conclusions: Adrenaline is a better middle ear haemostatic than haemocoagulase. However, haemocoagulase can safely be used in patients with hypertension.
超声诊断小儿结肠幼年性息肉合并肠套叠1例

讨论:幼年性结肠息肉常见于直肠,或整个结肠,偶见于胃或小肠,单纯的幼年性肠息肉常见于10岁以下儿童,以2~6岁为高发年龄。无家族史。为错构瘤性息肉,表现为非肿瘤性无规律的组织错构,具有肿瘤样增殖的特征。临床上常以反复腹痛及血便,合并肠套叠等急诊。典型肠道幼年性息肉的超声表现:①单发或多发的孤立性结节伴有筛网状囊状液性区;②结节旁可见低回声蒂与之相连;③CDFI可于蒂内及息肉内探及丰富的血流信号,呈“树枝征”或“雨伞征”。本例患儿常规腹部超声检查见肠套叠征象,行超声引导下水灌肠复位过程中观察息肉形态、位置、内部回声及血流情况,诊断较为直观准确。但在常规检查中患者如无明显症状及并发症,诊断上会遇到一定的难度。本病例超声表现典型,可加深基层医院的医师对幼年性肠息肉的认识。
超声心动图诊断胰腺癌合并二尖瓣、卵圆窝癌栓1例

讨论:胰腺癌是一种恶性度高、病程短并很快发生转移,侵犯邻近脏器的恶性肿瘤。本例患者自发现以来未行抗肿瘤治疗,肿瘤进展迅速、转移至多个脏器,甚至转移至心脏,目前国内胰腺癌转移至心脏尚未见报道。心脏转移的患者多已是癌症终末期,1年生存率几乎为零,治疗主要目的为减轻患者症状,改善生存质量。本例患者其他影像检查示胰腺、肝、肾、肺、肺均有癌栓影像,结合病史此患者心脏占位极有可能为转移性占位。超声心动图可直接观察心脏内占位性病变的位置、大小、形态结构、数目及活动度,优于其他有创检查,是诊断心脏占位性病变的首选方法。

Template/surfactant free and UV light irradiation assisted fabrication of Mn-Co oxides composite nanorings: Structure and synthesis mechanism

A facile, green, cost effective, and template or surfactant free strategy via a two-step route i.e. UV irradiation followed by dissolution-growth for the controlled synthesis of Mn-Co composite nanorings at room temperature was proposed. The nanorings structures and the process were systematically studied via TEM, HRTEM, EDX and XRD. Bir-MnO_2 nanosheets first formed through the direct photolysis of KMnO_4 under UV light irradiation. This was followed by a dissolution-growth process via the dissolution of Bir-MnO_2 nanosheets by the generated H+from the redox reaction between the added Co(NO_3)_2 and residual KMnO_4, as well as the accompanied formation of CoOOH, and Mn-Co composite nanorings. It was found that a balance between the dissolution and growth rate was needed. Suitable pH, KMnO_4 presence and the starting nanosheets like Bir-MnO_2 were the key factors for the formation of nanorings. The obtained Mn-Co nanorings/TiO_2 showed enhanced efficiency for the catalytic oxidation of HCHO. Based on the above understandings, it is believed that the developed dissolution-growth method can be adopted for the designing and preparation of other Mn-Co composite nanostructures which can be further applied for environmental pollution remediation.
Solar-driven high-temperature steam generation at ambient pressure

This paper demonstrates a facile solar steam generator for the generation of high-temperature steam at ambient pressure. The steam generator consists of a coiled copper tube (CCT) that serves as both solar collector and vapor heater. Both the inner and outer surfaces of the CCT are coated with black superhydrophobic copper oxide layer to improve the solar absorption, and such superhydrophobic layer prevents the condensation and clogging of water vapor during the heating process. Solar vapor is generated at the inlet of CCT through interfacial evaporation and subsequently heated inside the CCT as the vapor travels from the inlet to the outlet. By employing this approach, steam temperature that exceeds 100 °C under 1-sun illumination is demonstrated. Furthermore, steam temperature could reach as high as 250 °C under 10-sun illumination at ambient pressure. Successful sterilization experiment was also performed in this work to demonstrate the potential application of the high temperature steam generated. Such demonstrated approach helps open up the potential usage of solar-driven interfacial evaporation in applications that involve high-temperature steam, including medical sterilization, chemical manufacturing and food processing.
Adjustable thermal expansion in La(Fe, Si)_(13)-based conductive composites by high-pressure synthesis

Providing a suitable contact interface, where a high conductivity material with a desirable coefficient of thermal expansion (CTE) adjoins the target micro-electric devices, is very crucial to optimize the properties and service life of the relevant instruments. Regrettably, a high conductivity, low thermal expansion and relatively inexpensive material is very rare. Composites, fortunately, can offer a method to design materials with adjustable properties by mixing two or more diverse constituents. In this paper, high conductivity composites with adjustable thermal expansion were successfully prepared by a high-pressure synthesis. The composites are based on combining La(Fe,Si)_(13)-based compounds, the materials showing a giant, isotropic negative thermal expansion (NTE) properties, within Cu matrix. The La(Fe,Si)_(13)-based compounds were used to adjust the CTE of the composites, while the Cu phase is in charge of tuning the thermal conductivity properties. Thus, by changing the relative amount of the two components, the composites with high conductivities and adjustable CTE were achieved. Furthermore, the thermal expansion and magnetic properties of the composites were investigated by a physical property measurement system. The present results highlight the potential applications of the Cu-based high conductivity composites with room-temperature NTE properties in the thermal contacts to various semiconductor and microelectronic devices.
