An innovative approach was introduced for the development of a AA6063 recrystallization model. This method incorporated a regression-based technique for the determination of material constants and introduced novel equations for assessing the grain size evolution. Calibration and validation of this methodology involved a combination of experimentally acquired microstructural data from the extrusion of three different AA6063 profiles and results from the simulation using the Qform Extrusion UK finite element code. The outcomes proved the agreement between experimental findings and numerical prediction of the microstructural evolution. The trend of the grain size variation based on different process parameters has been accurately simulated， both after dynamic and static recrystallization， with an error rate of less than 25% in almost the whole sampling computations.

随着人们对绿色能源和环境友好型社会需求的日益增长,先进能量转换装置或系统的研发亟待加速,而燃料电池系统被认为是最有希望的未来发电装置。在不同种类的燃料电池中,固体氧化物燃料电池(SOFCs)是一种清洁环保的发电装置,因其独特的多燃料运行能力及能量转化效率高等优点而前景广阔。然而,传统使用镍-金属陶瓷阳极的SOFCs,在碳氢化合物燃料下运行时,由于燃料的不完全氧化会使阳极产生积碳,从而导致电池性能下降。讨论了碳基SOFC中碳沉积机理和解决阳极积碳的策略,重点介绍了目前广泛研究的具有混合离子-电子导体的双金属-金属陶瓷材料的种类以及研究进展,并总结了双金属-金属陶瓷材料的抗积碳机理,主要表现为降低阳极表面的碳沉积速率以及加速积碳的去除。还介绍了在还原性气氛中,钙钛矿材料中纳米粒子原位偏析的原理,并讨论了原位偏析所形成的纳米颗粒以及其与钙钛矿主体所形成的金属氧化物异质结构在抗积碳阳极中的应用。此外,还探究了多层阳极和单原子催化剂阳极在中温SOFCs中的应用。在燃料电池技术巨大进步的推动下,人们对可用于固定式发电的集成煤气化的燃料电池发电系统(IGFCs)产生了新的兴趣,该系统对于实现煤炭的清洁高效利用具有重要意义,该技术的关键依托于SOFCs的成熟度。最后,总结并指出了碳基SOFCs未来的一些研究方向。

TWIK-related potassium channels (TREK) belong to a subfamily of the two-pore domain potassium channels family with three members, TREK1, TREK2 and TWIK-related arachidonic acid-activated potassium channels. The two-pore domain potassium channels is the last big family of channels being discovered, therefore it is not surprising that most of the information we know about TREK channels predominantly comes from the study of heterologously expressed channels. Notw让hstanding, in this review we pay special attention to the limited amount of information available on native TREK-like channels and real neurons in relation to neuroprotection. Mainly we focus on the role of free fatty acids, lysophospholipids and other neuroprotective agents like riluzole in the modulation of TREK channels, emphasizing on how important this modulation may be for the development of new therapies against neuropathic pain, depression, schizophrenia, epilepsy, ischemia and cardiac complications.

Meningoencephalitis secondary to Listeria monocytogenes (L. monocytogenes) mainly affects newborns, the elderly and immunocompromised people;there are extremely rare cases in which said infection occurs in immunocompetent individuals. We present the case of a young adult patient without immunocompromise, who developed meningoencephalitis due to L. monocytogenes;This case is exceptional, since it occurred in an individual outside the classic age group, in addition to not having risk factors, which is why it should be considered an atypical causal agent.
