The chloride salts have great potential used as high-temperature thermal energy storage(TES) medium for the concentrated solar power system.In this study,LiCl,KCl and CaCl_(2) were selected as energy storage materials in order to further broaden the working temperature of ternary chloride salt and improve its energy storage density.The new high-temperature energy storage ternary chloride composed of LiCl,KCl,and CaCl_(2) was developed based on the phase diagram generated by FactSage.Three components of LiCl-KCl-CaCl_(2) with the mass ratio of 37.85%-53.38%-8.77%,30.90%-13.82%-55.28% and 1.78%-18.61%-79.61% were developed,of which the corresponding melting temperature(T_(m)) 340.93,433.57 and 626.85℃,respectively,was obtained either.Considering that T_(m) of the third group of salts was too high,only the first two groups of salts were tested.DSC test showed that the actual melting point was only 0.46% and 1.64% different from the melting point predicted by Factsage.The thermal properties of the two ternary chloride salts were also compared.The solid and liquid-specific heat of ternary salts was determined by DSC using sapphire as the standard reference.The vapor pressure and decomposition temperature of ternary chloride salts were investigated.The results showed that the vapor pressure of salt 1 was almost constant below 650℃ by FactSage.Meanwhile,the TG results showed that the upper working temperature of salt 1 was 650℃ under the air atmosphere.In addition,the ternary chloride salts after short-term cycling still exhibited excellent thermal properties,which revealed that these good thermal properties make them have broad application prospects in high-temperature thermal energy storage systems.

Importance: Eltrombopag has been recommended for pediatric immune thrombocytopenia (ITP). Response and adverse drug reactions (ADRs) varied widely between individuals, even at the same dose of eltrombopag. The appropriate eltrombopag concentration in ITP has not been reported.Objective: This study aims to explore the appropriate eltrombopag concentration in pediatric ITP.Methods: This was a single-center, prospective cohort study. Children diagnosed with refractory persistent/chronic ITP and platelet count < 30×109/L were treated with eltrombopag and followed up for at least 2 months. Concentration was detected by high-performance liquid chromatography-mass spectrometry at least 2 weeks after eltrombopag. The clinical characteristics-concentration, concentration-response, and concentration-ADRs were analyzed.Results: A total of 30 patients were enrolled, comprising 13 males and 17 females, with a median age of 72 (45-94) months. The median dose and concentration were 1.39 (1.09-1.56) mg/kg and 2.70 (2.25-4.13) mg/L, respectively. Of the enrolled patients, 14 responded to treatment, whereas 16 did not. Additionally, five experienced adverse drug reactions. No linear correlation was observed between eltrombopag concentration and clinical characteristics. The concentration was lower in the response group than in the nonresponse group, but there was no significant difference (t = 0.755,P = 0.457). Patients who experienced ADRs had a higher concentration than those without ADRs (t = 2.538,P = 0.017). The area under the receiver operating characteristic curve of ADRs was 0.78 (95% confidence interval: 0.56-1.00). Youden’s index identified the cutoff point as 4.33 mg/L, with a sensitivity of 88% and a specificity of 60%. Logistic regression analysis demonstrated that a higher platelet count before eltrombopag predicted a favorable response.Interpretation: Eltrombopag proves efficacious and well-tolerated for treating pediatric ITP. However, prolonged and high-dose administration may increase the likelihood of ADRs. Thus

Spiking neural network(SNN),widely known as the third-generation neural network,has been frequently investigated due to its excellent spatiotemporal information processing capability,high biological plausibility,and low energy consumption characteristics.Analogous to the working mechanism of human brain,the SNN system transmits information through the spiking action of neurons.Therefore,artificial neurons are critical building blocks for constructing SNN in hardware.Memristors are drawing growing attention due to low consumption,high speed,and nonlinearity characteristics,which are recently introduced to mimic the functions of biological neurons.Researchers have proposed multifarious memristive materials including organic materials,inorganic materials,or even two-dimensional materials.Taking advantage of the unique electrical behavior of these materials,several neuron models are successfully implemented,such as Hodgkin–Huxley model,leaky integrate-and-fire model and integrate-and-fire model.In this review,the recent reports of artificial neurons based on memristive devices are discussed.In addition,we highlight the models and applications through combining artificial neuronal devices with sensors or other electronic devices.Finally,the future challenges and outlooks of memristor-based artificial neurons are discussed,and the development of hardware implementation of brain-like intelligence system based on SNN is also prospected.

Heavily doped upconversion nanoparticles(UCNPs)potentially have exceptional photon upconversion abilities that are promising for diverse applications,such as lasing and super-resolution microscopy.However,heavily doped UCNPs typically can only offer mediocre upconversion luminescence intensity,and there still lacks general guidelines for the design and synthesis of heavily doped UCNPs.Herein,in order to boost the upconversion luminescence of heavily doped UCNPs,we studied the influence of characteristics of the core-shell structure on heavily doped UCNPs'upconversion luminescence.We find that some empirical guidelines derived from conventional UCNPs are not suitable for heavily doped UCNPs.Using NaYbF_(4):Tm@NaYF_(4) core-shell UCNPs with a high concentration of Yb_(3+)as a representative,our studies reveal that a rather thick inert NaYF4 shell is needed to protect the UCNPs from surface quenching,and the upconversion luminescence may undergo the cooperative sensitization process,which should be due to the highly concentrated Yb~(3+)dopant.In addition,the upconversion luminescence of heavily doped NaYbF4:Tm UCNPs exhibits no obvious dependence on the type of inert shell.Furthermore,our results show that confining both Yb~(3+)and Tm~(3+)dopants in a thin layer(known as theδ-doping strategy)does not work well in the heavily doped UCNPs.Accordingly,we propose a NaYbF_(4):Tm@NaYbF_(4)@NaYF_(4) core-shell-shell structure to enhance the luminescence of heavily doped UCNPs,by weakening the dissipation of excitation energy and strengthening the absorption.These findings should be helpful to establish general design principles for developing the brightest possible UCNPs that can meet the requirements of various applications.

叶片化学计量特征能反映植物对周围环境的适应性,研究两者之间的关系有助于探究植物对典型荒漠环境的适应策略。本研究以国家二级重点保护植物沙冬青为研究对象,设置26个典型样地,测定了叶片碳(C)、氮(N)、磷(P)含量和水分利用效率(WUE),分析叶片化学计量特征与WUE之间的协同关系,同时量化土壤、气候因子和水分利用效率对叶片化学计量特征变化规律的解释量。结果表明:沙冬青叶片C、N和P含量均值分别为(583.99±27.93)、(24.31±2.09)、(1.83±0.06)mg·g^(-1);变异系数分别为4.8%、8.6%、3.2%,均属弱变异性,表明沙冬青叶片C、N和P含量趋向于某一稳定值,沙冬青叶片N:P平均值为13.3,说明沙冬青生长主要受N元素限制。WUE与沙冬青叶片C含量不相关,与叶片N、P含量和N:P呈显著正相关关系,与C:N和C:P呈显著负相关关系,这说明WUE与叶片养分含量存在明显的线性协同变化趋势。影响叶片C含量和C:P的主要是气候因子,影响叶片N含量和N:P的主要是土壤因子,影响叶片P含量和C:N的主要是水分利用效率,这表明不同化学计量特征的驱动因子各不相同。本研究结果有助于评估荒漠植物沙冬青栖息地的适宜性,可为沙冬青的科学保护和管理提供理论依据。
