Macrophages are essential components of the innate immune system and constitute a non-specific first line of host defense against pathogens and inflammation.Mitochondria regulate macrophage activation and innate immune responses in various inflammatory diseases,including cochlear inflammation.The distribution,number,and morphological characteristics of cochlear macrophages change significantly across different inner ear regions under various pathological conditions,including noise exposure,ototoxicity,and age-related degeneration.However,the exact mechanism underlying the role of mitochondria in macrophages in auditory function remains unclear.Here,we summarize the major factors and mitochondrial signaling pathways(e.g.,metabolism,mitochondrial reactive oxygen species,mitochondrial DNA,and the inflammasome)that influence macrophage activation in the innate immune response.In particular,we focus on the properties of cochlear macrophages,activated signaling pathways,and the secretion of inflammatory cytokines after acoustic injury.We hope this review will provide new perspectives and a basis for future research on cochlear inflammation.

Ammonia(NH_(3))emission has caused serious environment issues and aroused worldwide concern.The emerging ionic liquid(IL)provides a greener way to efficiently capture NH_(3).This paper provides rigorous process simulation,optimization and assessment for a novel NH_(3)deep purification process using IL.The process was designed and investigated by simulation and optimization using ionic liquid[C_(4)im][NTF_(2)]as absorbent.Three objective functions,total purification cost(TPC),total process CO_(2)emission(TPCOE)and thermal efficiency(ηeff)were employed to optimize the absorption process.Process simulation and optimization results indicate that at same purification standard and recovery rate,the novel process can achieve lower cost and CO_(2)emission compared to benchmark process.After process optimization,the optimal functions can achieve 0.02726$/Nm~3(TPC),311.27 kg CO_(2)/hr(TP-COE),and 52.21%(ηeff)for enhanced process.Moreover,compared with conventional process,novel process could decrease over$3 million of purification cost and 10000 tons of CO_(2)emission during the life cycle.The results provide a novel strategy and guidance for deep purification of NH_(3)capture.

1.Text Black phosphorus(BP)has sparked immense interests among two-dimensional(2D)nanomaterials since its first mechanical exfoliation from bulk BP in 2014[1].The atoms in BP are not distributed in the same plane,where the lone pair electrons of P atoms are highly reactive,and the structural anisotropy leads to many distinctive physical properties[2,3],like highly anisotropic effective masses and tunable electronic properties[4].Particularly,it possesses thickness-dependent direct bandgap values from 0.3 eV(bulk)to 1.5 eV(monolayer)[5].Owing to its unique structural and electronic properties,BP shows potential applications in electronic or optoelectronic devices[6-8].However,BP is reported to be unstable and easy to decompose in ambient conditions,which hinders its wide applications[9].Layered BP can rapidly transform into oxides,and further degrade into acids or salts within hours[10].Therefore,it is necessary to take some measures to inhibit the degradation of BP.

Inserting hexagonal boron nitride(hBN)as barrier layers into bilayer transition metal dichalcogenides heterointerface has been proved an efficient method to improve two dimensional tunneling optoelectronic device performance.Nevertheless,the physical picture of interlayer coupling effect during incorporation of monolayer(1L-)hBN is not explicit yet.In this article,spectroscopic ellipsometry was used to experimentally obtain the broadband excitonic and critical point properties of WS_(2)/MoS_(2)and WS_(2)/hBN/MoS_(2)van der Waals heterostructures.We find that 1L-hBN can only slightly block the interlayer electron transfer from WS_(2)layer to MoS_(2)layer.Moreover,insertion of 1L-hBN weakens the interlayer coupling effect by releasing quantum confinement and reducing efficient dielectric screening.Consequently,the exciton binding energies in WS_(2)/hBN/MoS_(2)heterostructures blueshift comparing to those in WS_(2)/MoS_(2)heterostructures.In this exciton binding energies tuning process,the reducing dielectric screening effect plays a leading role.In the meantime,the quasi-particle(QP)bandgap remains unchanged before and after 1L-hBN insertion,which is attributed to released quantum confinement and decreased dielectric screening effects canceling each other.Unchanged QP bandgap as along with blueshift exciton binding energies lead to the redshift exciton transition energies in WS_(2)/hBN/MoS_(2)heterostructures.

Graphene-based photodetectors have drawn a large amount of interests owing to its wide spectral response,however,the high dark current greatly limits their applications.In this study,we develop an efficient graphene in-plane homogeneous p-n-p junction based infrared(IR) photodetector with greatly reduced dark current.The devices with p-n-p junctions exhibit excellent photoresponse to 1.0～4.0 μm IR light illumination with ultra-low dark current at the order of～10-9A in double p-n-p junctions and 10-13A in three p-n-p junctions based photodetector,which is three and seven orders of magnitude lower than pristine graphene phototransistors,respectively.The excellent IR photodetection capabilities could be attributed to the synergistic effects of in-plane photovoltaic effects as well as the photogating effects induced carrier injection from the silicon substrate.Our results suggest intriguing potential of graphene in-plane p-n-p junctions for applications in high-performance IR photodetectors.

Conjugated polymers have been explored as promising hole-transporting layer(HTL)in lead sulfide(PbS)quantum dot(QD)solar cells.The fine regulation of the inorganic/organic interface is pivotal to realize high device performance.In this work,we propose using CsPbI_(3) QDs as the interfacial layer between PbS QD active layer and organic polymer HTL.The relative soft perovskite can mediate the interface and form favorable energy level alignment,improving charge extraction and reducing interfacial charge recombination.As a result,the photovoltaic performance can be efficiently improved from 10.50%to 12.32%.This work may provide new guidelines to the device structural design of QD optoelectronics by integrating different solutionprocessed semiconductors.

为提高轴流压气机叶型优化设计水平,提出了一种基于吸力面叠加厚度分布的参数化造型方法,结合基于Kriging代理模型与差分进化的代理优化方法开发了一套优化设计平台,并将吸力面控制参数作为优化变量,对某跨声与超声叶型进行性能优化。结果表明:基于吸力面叠加厚度分布的叶片造型方法能对叶型进行较好的表达,并成功应用在优化设计平台中。跨声、超声优化叶型在设计点损失分别降低了10.66%与7.4%。分析表明:跨声优化叶型的主要特征是吸力面型线前缘附近型线弯度降低,使得激波强度降低,激波损失与边界层损失降低,同时中后部位置处的负荷增大,扩张通道扩压能力增强;超声叶型优化由于边界层影响更显著,因此还需要更多考虑吸力面扩张通道区域型线;叶型喉部位置与喉部宽度会影响堵塞冲角的变化。

Rapid amplification of cDNA ends (RACE) and real-time polymerase chain reaction (RT-PCR) were carried out to analyze the CYP4 gene expression in polychaete Marphysa sanguinea exposed to benzo[a]pyrene (BaP) in this study. The full length of MsCYP4 cDNA was 2 470 bp, and it encoded 512 amino acids. The deduced amino acid sequence showed 47% identity with CYP4F from frog Xenopus tropicalis and shared high homology with other known CYP4 sequences. To analyse the role of CYP4 in protecting M. sanguinea from BaP exposure, three BaP groups were established: 0.5, 5 and 50 μg/L. Polychaetes were sampled after 3, 7 and 12 d. At 0.5 μg/L, the effect of BaP on MsCYP4 gene expression increased with time prolonged. MsCYP4 gene expression curve showed Ushaped trend with time in 5 and 50 μg/L BaP groups. Therefore, MsCYP4 gene may play an important role in maintaining the balance of cellular metabolism and protecting M. sanguinea from BaP toxicity.
