Quasi-type II heterostructured nanocrystals(NCs)have been of particular interest due to their great potential for controlling the interplay of charge ***,the lack of material choices for quasi-type II NCs restricts the accessible emission wavelength from red to near-infrared(NIR),which hinders their use in light-emitting applications that demand a wide range of visible ***,we demonstrate a new class of quasi-type II nanoemitters formulated in ZnSe/ZnSe_(1-X)Te_(X)/ZnSe seed/spherical quantum well/shell heterostructures(SQWs)whose emission wavelength ranges from blue to *** a given geometry,ZnSe_(1-X)Te_(X) emissive layers grown between the ZnSe seed and the shell layer are strained to fit into the surrounding media,and thus,the lattice mismatch between ZnSe_(1-X)Te_(X) and ZnSe is effectively *** addition,composition of the ZnSe_(1-X)Te_(X) emissive layer and the dimension of the ZnSe shell layer are engineered to tailor the distribution and energy of electron and hole wave *** from the capabilities to tune the charge carriers on demand and to form defectfree heterojunctions,ZnSe/ZnSe_(1-X)Te_(X)/ZnSe/ZnS NCs show near-unity photoluminescence quantum yield(PLQY>90%)in a broad range of emission wavelengths(peak PL from 450nm to 600 nm).Finally,we exemplify dichromatic white NC-based light-emitting diodes(NC-LEDs)employing the mixed layer of blue-and yellow-emitting ZnSe/ZnSe_(1-X)TeX/ZnSe/ZnS SQW NCs.

Laser-structuring is an effective method to promote ion diffusion and improve the performance of lithium-ion battery(LIB)*** this work,the effects of laser structuring parameters(groove pitch and depth)on the fundamental characteristics of LIB electrode,such as interfacial area,internal resistances,material loss and electrochemical performance,are investigated,LiNi_(0.5)Co_(0.2)Mn_(0.3)O_(2) cathodes were structured by a femtosecond laser by varying groove depth and pitch,which resulted in a material loss of 5%-14%and an increase of 140%-260%in the in terfacial area between electrode surface and *** is shown that the importance of groove depth and pitch on the electrochemical performance(specific capacity and areal discharge capacity)of laser-structured electrode varies with current *** pitch is more im porta nt at low current rate but groove depth is at high curre nt *** the mapping of lithium concentration within the electrodes of varying groove depth and pitch by laser-induced breakdown spectroscopy,it is verified that the groove functions as a diffusion path for lithium *** ionic,electronic,and charge transfer resistances measured with symmetric and half cells showed that these internal resistances are differently affected by laser structuring parameters and the changes in porosity,ionic diffusion and electronic *** is demonstrated that the laser structuring parameters for maximum electrode performance and minimum capacity loss should be determined in consideration of the main operating conditions of LIBs.

研究了金属间化合物厚度对蜂窝状棒材热性能和力学性能的影响。在200℃下采用重复静液挤压制备Al/Cu蜂窝状棒材。在制备过程中,Al/Cu界面生成1μm厚的金属间化合物层。经420℃退火0.5-2 h后续热处理后,可获得不同厚度的金属间化合物层,最厚可达10.1μm。经鉴定,金属间化合物层为Al2Cu（θ）、AlCu（η2）和Al4Cu9（γ1）相。随着金属间化合物层厚度的增加,纵向和截面方向上的热导率分别减小11.9%（从（268±4.8）到（236±4.4）W/（m·K））和10.4%（从（210±3.2）到（188±2.8）W/（m·K））,Al/Cu蜂窝状棒材的抗拉强度和伸长率分别是（103±8.4）MPa和（73±6.2）%。当金属间化合物层厚度达到7.7μm时,抗拉强度增加至（131±6.5）MPa,随着金属间化合物层厚度增加至10.1μm时,抗拉强度降低至（124±3.9）MPa。随着金属间化合物层厚度增加,蜂窝状棒材的伸长率急剧下降至（29±2.5）%。

利用韩国豹猫的IRBP、12S rRNA和细胞色素b(Cyt b)序列,并将其与Gen Bank中的豹猫及西表猫的上述基因进行比较,以此来重新分析韩国豹猫和其它豹猫及西表猫之间的遗传分化情况。首先,我们从18只韩国豹猫的IRBP、12S rRNA和Cyt b序列分析中分别检测到6个等位基因、1个单倍型和3个单倍型,推测曾经发生在豹猫种群的瓶颈事件可能是本文发现的不同分子标记之间存在基因型丢失差异的原因。基于Cyt b序列分析,证实东亚的豹猫形成一个单独的进化枝,本文得到的Cyt b序列和之前发布结果支持一个分类理论,即认为东亚的豹猫就是东北森林猫。我们发现在IRBP、12S rRNA基因上,韩国豹猫和西表猫存在相同的序列,支持将西表猫和豹猫视为同一物种。

Background No study has thoroughly compared the effectiveness of combined antiplatelet treatments(other than clopidogrel–aspirin)versus clopidogrel–aspirin or aspirin alone for early secondary prevention in acute ischaemic *** We identified patients with acute,minor,non-cardiogenic ischaemic stroke treated with aspirin alone,clopidogrel–aspirin or other combination *** scores considering the inverse probability of treatment weighting were used to adjust for baseline *** primary outcome was the composite of all strokes(ischaemic or haemorrhagic),myocardial infarction and all-cause mortality at 3 *** Among 12234 patients(male:61.9%;age:65.5±13 years)who met the eligibility criteria,aspirin,clopidogrel–aspirin and other combination treatments were administered in 52.2%,42.9%and 4.9%of patients,*** the crude analysis,the primary outcome event at 3 months occurred in 14.5%of the other combination group,14.4%of the aspirin group and 13.0%of the clopidogrel–aspirin *** the weighted Cox proportional hazards analysis,the 3-month primary outcome event occurred less frequently in the clopidogrel–aspirin group than in the other combination group(weighted HR:0.82(0.59–1.13)),while no association was found between the aspirin group(weighted HR:1.04(0.76–1.44))or other combination group and the 3-month primary *** Other combined antiplatelet treatment,compared with aspirin alone or clopidogrel–aspirin,was not associated with reduced risks of primary composite vascular events or recurrent stroke during the first 3 months after ***,the results suggest that other combination treatments,particularly the cilostazol-based combination,may not be effective alternatives for clopidogrel–aspirin to prevent early vascular events in patients with acute minor *** exploration in clinical trials will be needed.

Objective The Mediodorsal thalamus(MD) is a part of the limbic system and connects reciprocally with the prefrontal cortex,the amygdala and the hippocampus,which comprise a network of structures involved in fear memory. However,the contribution of the MD to fear behavior is poorly *** C(PLC) b4 is expressed intensely in the MD but very lightly in the prefrontal cortex and the amygdala,the two key regions known to regulate fear *** Here,we examined a role of the MD using the PLCb4 knock-out(PLCb4) mice in the formation and extinction of auditory-conditioned *** The PLCb4 mice showed normal acquisition and long-term memory of auditory-conditioned ***,the mutant was severely impaired in fear *** clamp recording on the mutant MD neurons in thalamic slices showed an increase of low threshold Ca currents mediated via T-type Ca channels compared to the wild *** infusion in vivo of T-type channel blocker into the MD ameliorated the impaired extinction phenotype in PLCb4 and facilitated the extinction in wild type *** These results suggest that the mediodorsal thalamus is involved in the control of fear extinction and T-type Ca channels play an inhibitory role in this process.
