From Microstructure to Macroscopic Performance: A Comprehensive Study on Low‐K Oxide‐Doped BNT–LST–NN Ceramics for Energy Storage

open access: yesRare Metals, EarlyView.
ABSTRACT Dielectric ceramics are popular for energy storage materials because of their rapid charge–discharge characteristics, whereas their low energy density and efficiency hinder their miniaturization and integration. In this work, the energy storage performance is significantly enhanced through introducing Al2O3 and TiO2 into the 0.425(Bi0.5Na0.5 ...

Surface‐Embedded Ag@Multilayer Graphene for Photothermal‐Enhanced Superhydrophobic Anti‐Icing Coatings

open access: yesRare Metals, EarlyView.
ABSTRACT Harnessing solar energy for self‐heating presents an effective strategy to suppress surface ice formation. In this paper, we fabricated nano‐silver‐modified multilayer graphene sheets (Ag@MGs) that integrate photothermal and superhydrophobic properties for anti‐icing applications.

On the Damage Tolerance of Diffusion Bonded Titanium–Aluminum Phase Biomimetic Composites

open access: yesRare Metals, EarlyView.
ABSTRACT The biomimetic design principles of natural structures involve the strategic integration of stiff and compliant phases to synergistically enhance strength and toughness. Its evolutionary refined natural armor, characterized by a specialized microarchitecture, enables superior damage tolerance.

Induced Pluripotent Stem Cell-derived Mesenchymal Stem Cells Improve Crohn’s Disease via Altered T Cell Differentiation [PDF]

open access: yes, 2015
背景&目的:目前,有许多研究表明,无论是脂肪来源还是骨髓来源的的间充质干细胞都对克罗恩病和溃疡性结肠病实验室模型有益。甚至有些临床的一期实验,已经证明了间充质干细胞可以缓解炎症性肠病的临床症状和组织病理学损伤。然而,限制间充质干细胞临床研究与应用的最主要原因就是间充质干细胞在组织中的含量有限,很难得到充足的干细胞,满足临床研究和应用的需求,并且提取细胞的过程也会给病人或者细胞捐献者带来极大的痛苦。在此,我们的研究目的主要是探讨另一种新型来源的间充质干细胞即诱导多能干细胞来源的间充质干细胞(iPSC ...

Using miniaturized laboratory equipment and DNA barcoding to improve conservation genetics training and identify illegally traded species

open access: yesConservation Biology, EarlyView.
Abstract Illegal wildlife trade (IWT) is one of the largest global illegal activities, and it negatively affects biodiversity and sustainable development worldwide. DNA barcoding coupled with high‐throughput sequencing (i.e., metabarcoding) is useful in identifying taxa affected by IWT and has been used routinely for decades.

In vitro culture, cryopreservation, and field reintroduction of the endangered Mingan thistle

open access: yesConservation Biology, EarlyView.
Abstract Current plant conservation efforts are hindered by, for example, poor seed germination, low viability, and insufficient propagation and preservation technologies. To address these problems, we devised an approach to plant conservation that integrates conservation, preservation, and restoration (CPR), which uses advanced in vitro techniques. We

Screening and application of aptamers to Staphylococcus aureus Toxic Shock Syndrome Toxin-1 [PDF]

open access: yes, 2016
摘要 目的:金黄色葡萄球菌(Staphylococcusaureus)分泌的毒性休克综合征毒素-1(ToxicShockSyndromeToxin-1,TSST-1)引发中毒性休克综合征(ToxicShockSyndrome,TSS),通过激活T淋巴细胞使其活化、增殖,引起强烈的免疫应答。目前针对TSST-1本身的治疗手段不多,合成寡核苷酸文库和亲和力筛选作为获得高亲和力、高特异性适配体(Aptamer)的一种方便、快捷、有效的方法。本研究利用指数富集的配体系统进化技术 ...

Effects of landscape context on avian specialist response to increased surface temperature in protected areas

open access: yesConservation Biology, EarlyView.
Abstract Human development is a driver of global change and a major threat to biodiversity. Protected areas maintain and support biodiversity, but outside stressors, such as climate change and land use change, can negatively influence natural resources within protected areas.

The Expression and Biological Significance of PD-L1 on Lung Cancer Cell Lines [PDF]

open access: yes, 2009
Background and objective Tumor-associated PD-L1 expression was recently shown to promote T-cell apoptosis and proposed as a potential mechanism of immune evasion by tumors. On the basis of the ability of tumor-associated PD-L1 to mediate activated T-cell
