| 1 | Ultrafast synthesis and sintering of materials in a single running experiment approach by using electric fields显示文摘Processing of materials in the form of ceramics normally involves several steps including calcination at a relatively low temperature for synthesis of the end-product powder and sintering at a high temperature for densification.The work we have been developing introduces a novel approach enabling synthesis plus sintering of materials in a single running experiment by using electric fields,ending with dense ceramics that display grains noticeably finer than in conventional processing.This new paradigm is fully illustrated with experiments conducted on amorphous CaCu3Ti4O12 precursor powder,shown to experience,on heating,crystallization through intermediate phases,followed by chemical reaction leading to synthesis of the end-product powder,plus densification depending on field adjustment.The processing time and furnace temperature are considerably reduced,demonstrating that enhanced synthesis and sintering rates applied under field input.Similar results found in Bi2/3Cu3Ti4O12are also shown.The different factors that may contribute to this unique scenario,including Joule heating,defect generation,and reduction of free energy for nuclei formation promoted by the applied field,are briefly discussed.Overall,the findings we bring here are exclusive as they show an exploitable way that allows rapid processing of materials with good control over particle and grain coarsening. | Lílian M.JESUS Ronaldo S.SILVA Jean-Claude M’PEKO | 2019 | Journal of Advanced Ceramics2019，8，2： | 2 |

| 4 | 鱼肌肉蛋白质组学分级过程的重现性研究显示文摘在比较蛋白质组学中,分级过程经常被用于去除高丰度蛋白质,从而提高低丰度蛋白质的浓度至检出限以上。作者为了证实在二维凝胶电泳分离流程中增加额外的分级过程将会减小对金头鲷宰前应激响应时间依赖检测中所引入的噪声和批次间的偏差,采用多维标度对结果数据进行了多参数分析。结果表明生物响应比分级引入的误差高出几个数量级,而批次间误差不小于不同IEF/SDS-PAGE运行所引入的偏差。 | ToméS.SILVA Odete CORDEIRO Flemming JESSEN Jorge DIAS Pedro M.RODRIGUES | 2010 | 生命科学仪器2010，8，4： | 0 |
| 5 | Multi-mechanical waves against Alzheimer’s disease pathology:a systematic review显示文摘Alzheimer’s disease(AD)is the most common cause of dementia,afecting approximately 40 million people worldwide.The inefectiveness of the available pharmacological treatments against AD has fostered researchers to focus on alternative strategies to overcome this challenge.Mechanical vibrations delivered in diferent stimulation modes have been associated with marked improvements in cognitive and physical performance in both demented and nondemented elderly.Some of the mechanical-based stimulation modalities in eforts are earlier whole-body vibration,transcranial ultrasound stimulation with microbubble injection,and more recently,auditory stimulation.However,there is a huge variety of treatment specifcations,and in many cases,conficting results are reported.In this review,a search on Scopus,PubMed,and Web of Science databases was performed,resulting in 37 papers.These studies suggest that mechanical vibrations delivered through diferent stimulation modes are efective in attenuating many parameters of AD pathology including functional connectivity and neuronal circuit integrity defcits in the brains of AD patients,as well as in subjects with cognitive decline and non-demented older adults.Despite the evolving preclinical and clinical evidence on these therapeutic modalities,their translation into clinical practice is not consolidated yet.Thus,this comprehensive and critical systematic review aims to address the most important gaps in the reviewed protocols and propose optimal regimens for future clinical application. | Francisca Monteiro Ioannis Sotiropoulos Óscar Carvalho Nuno Sousa Filipe S.Silva | 2021 | Translational Neurodegeneration2021，10，3： | 0 |
| 6 | How does zebrafish support new strategies for neuroprotection and neuroregeneration in hypoxia-related diseases?显示文摘Hypoxia is a condition found commonly in several disorders,such as ischemia,asthma,anemia and neonatal hypoxia.Individuals subjected suddenly to high altitude or extreme exercise are also challenged to low oxygen(O_2)levels.Since the brain presents elevated basal O_2 consumption,this organ is readily affected by hypoxia.For this reason,cerebral hypoxia has | Emerson S.Silva Joao Batista T.Rocha Diogo O.Souza Marcos M.Braga | 2016 | Neural Regeneration Research2016，11，7： | 0 |

| 8 | Non-aerated liquid culture promotes shoot organogenesis in Eucalyptus globulus Labill显示文摘Eucalyptus is very recalcitrant to in vitro culture.In this research, an efficient shoot organogenesis system was developed using 60-day-old plants of Eucalyptus globulus grown in vitro and non-aerated liquid medium to improve shoot proliferation. Cultures were initiated with hypocotyls and leaf segments from plantlets cultivated on semisolid 1/2 MS modified medium supplemented with 4.44 μM 6-Benzyladenine(BA) and 16.1 μM 1-Naphthaleneacetic acid(NAA). Calli were transferred to shoot induction medium, with either 0.5 or 2.7 μM NAA. Shoot multiplication was carried out on 4.44 μM BA + 0.5 μM NAA medium, and semisolid and non-aerated liquid systems were compared for improving shoot proliferation.Rooting of adventitious shoots was evaluated on medium containing NAA or Indole-3-butyric acid-IBA(5 and16 μM). Callogenesis was obtained from both types of explants, although shoot formation was only obtained from leaf-derived calli. Shoot proliferation on 4.44 μM BA+0.5 μM NAA resulted in the most shoots/callus.Non-aerated liquid medium was more efficient in promoting shoot multiplication(53.5 shoots/callus) than was semisolid medium(28.5 shoots/callus). Levels of phenolic compounds were significantly reduced in the shoots cultivated in liquid medium. Efficient rooting(76%) was obtained using 16 μM IBA. | T.D.Salla C.dos S.Silva K.L.de G.Machado L.V.Astarita E.R.Santarém | 2018 | Journal of Forestry Research2018，29，3： | 0 |
| 9 | QUASILINEAR EQUATIONS USING A LINKING STRUCTURE WITH CRITICAL NONLINEARITIES显示文摘It is to establish existence of a weak solution for quasilinear elliptic problems assuming that the nonlinear term is critical.The potential V is bounded from below and above by positive constants.Because we are considering a critical term which interacts with higher eigenvalues for the linear problem,we need to apply a linking theorem.Notice that the lack of compactness,which comes from critical problems and the fact that we are working in the whole space,are some obstacles for us to ensure existence of solutions for quasilinear elliptic problems.The main feature in this article is to restore some compact results which are essential in variational methods.Recall that compactness conditions such as the Palais-Smale condition for the associated energy functional is not available in our setting.This difficulty is overcame by taking into account some fine estimates on the critical level for an auxiliary energy functional. | Edcarlos D.SILVA Jefferson S.SILVA | 2022 | Acta Mathematica Scientia2022，42，3： | 0 |
