    自从近30年前首次引入全细胞生物报道分子(WCB)以来,他们的高灵敏度,选择性,和现场检测的适用性使它们在环境监测中具有很大的前景,医学诊断,食品安全,生物制造,和其他领域。特别是在环境领域,该技术提供了一种快速有效的方法来评估环境中污染物的生物利用度。尽管有这些优势,该技术尚未商业化。这种商业化的缺乏令人困惑,鉴于WCBs广阔的应用前景。多年来,许多研究论文主要集中在增强WCB的灵敏度和选择性上,很少关注它们更广泛的商业应用。到目前为止,目前还没有关于这个主题的批判性审查。因此,在本文中,我们批判性地回顾了WCB在过去三十年中的研究进展,评估当前系统的性能和局限性,以了解商业部署的障碍。通过识别这些障碍,本文为研究人员和行业利益相关者提供了对阻碍市场进入的挑战的更深入的见解,并激发了克服这些障碍的进一步研究,从而促进WCB的商业化,作为一种有前途的环境监测技术。
    Since the initial introduction of whole-cell bioreporters (WCBs) nearly 30 years ago, their high sensitivity, selectivity, and suitability for on-site detection have rendered them highly promising for environmental monitoring, medical diagnosis, food safety, biomanufacturing, and other fields. Especially in the environmental field, the technology provides a fast and efficient way to assess the bioavailability of pollutants in the environment. Despite these advantages, the technology has not been commercialized. This lack of commercialization is confusing, given the broad application prospects of WCBs. Over the years, numerous research papers have focused primarily on enhancing the sensitivity and selectivity of WCBs, with little attention paid to their wider commercial applications. So far, there is no a critical review has been published yet on this topic. Therefore, in this article we critically reviewed the research progress of WCBs over the past three decades, assessing the performance and limitations of current systems to understand the barriers to commercial deployment. By identifying these obstacles, this article provided researchers and industry stakeholders with deeper insights into the challenges hindering market entry and inspire further research toward overcoming these barriers, thereby facilitating the commercialization of WCBs as a promising technology for environmental monitoring.

    自从发现四苯基乙烯衍生物的聚集诱导发射以来,已经探索了各种方法来制备高效的多色发光材料。在这里,我们报告了一种简单有效的策略,用于构建四阳离子发光体的发光有机盐,四吡啶-四苯基乙烯(T4Py-TPE4+),结合七个二-和四-阴离子芳族磺酸盐配体。当阳离子发光剂和阴离子配体的水溶液混合时,它们在几秒钟到几分钟内迅速聚集成有机盐,收益率高达90%以上。伴随着排放效率从58%增加到几乎100%,以及在511和586nm之间调谐发射颜色的能力。这些改进主要归因于阳离子和阴离子之间的强静电吸引力,导致形成具有各种π共轭长度的T4Py-TPE4发光体的刚性疏水网络。因为这些化合物是市售的,这种方法开辟了制造用于器件制造和研究的新型发光材料的可能性。
    Since the discovery of aggregation-induced emission from tetraphenylethylene derivatives, various methods have been explored to prepare highly efficient multicolored luminescent materials. Herein, we report a simple and efficient strategy for constructing luminescent organic salts of the tetracationic luminogen, tetrapyridinium-tetraphenylethylene (T4Py-TPE4+), combined with seven di- and tetra-anionic aromatic sulfonate ligands. When aqueous solutions of the cationic luminogen and the anionic ligands were mixed, they rapidly aggregated into organic salts within seconds to minutes, giving yields of up to >90%. This was accompanied by an increase in the emission efficiency from ∼58% to almost 100%, and the ability to tune the emission color between 511 and 586 nm. These improvements were mainly attributed to the strong electrostatic attractions between the cation and anions, which resulted in the formation of a rigid hydrophobic network of the T4Py-TPE4+ luminogen with various π-conjugation lengths. Because these compounds are commercially available, this method opens the possibility of fabricating novel light-emitting materials for device fabrication and research.

    为了满足对高能锂离子电池(LIB)不断增长的需求,开发下一代负极材料势在必行。与传统的碳基阳极相比,基于Si的材料由于其高理论容量和合理的成本而具有前景。SiOx,作为硅衍生物阳极候选,特别令人鼓舞的是其持久的循环寿命,它的实际应用是,然而,严重阻碍了低初始库仑效率(ICE),导致持续的锂消耗。更糟糕的是,低ICE也容易引发可怕的连锁反应,导致不良的循环稳定性。为了进一步开发SiOx阳极,研究人员对其工作/失败机制有了深入的了解,以便进一步提出有效的补救措施来缓解低ICE。在这个意义上,本文最近的研究调查了从根本上导致SiOx低ICE的可能原因,在此基础上,讨论和总结了解决低ICE问题的各种解决方案,及时总结。这种观点为高ICESiOx阳极的合理设计提供了有价值的见解,并为SiOx作为下一代LIB阳极的工业应用铺平了道路。
    To meet the ever-increasing demand for high-energy lithium-ion batteries (LIBs), it is imperative to develop next-generation anode materials. Compared to conventional carbon-based anodes, Si-based materials are promising due to their high theoretical capacity and reasonable cost. SiOx, as a Si-derivative anode candidate, is particularly encouraging for its durable cycling life, the practical application of which is, however, severely hindered by low initial Coulombic efficiency (ICE) that leads to continuous lithium consumption. What is worse, low ICE also easily triggers a terrible chain reaction causing bad cycling stability. To further develop SiOx anode, researchers have obtained in-depth understandings regarding its working/failing mechanisms so as to further propose effective remedies for low ICE mitigation. In this sense, herein recent studies investigating the possible causes that fundamentally result in low ICE of SiOx, based on which a variety of solutions addressing the low ICE issue are discussed and summarized, are timely summarized. This perspective provides valuable insights into the rational design of high ICE SiOx anodes and paves the way toward industrial application of SiOx as the next generation LIB anode.

    外来品种的引进和育种公司新品系的培育,对华南地区的土鸡提出了挑战,包括品种特征的丧失,降低遗传多样性,纯度下降。了解中国南方土鸡的种群遗传结构和遗传多样性对于进一步推进育种工作至关重要。在这项研究中,我们分析了来自中国南方10个不同品种的321个个体的群体遗传结构和遗传多样性。通过比较商业鸡和本地鸡,我们确定了在本地鸡和商业品种之间发生的选择特征。对种群遗传结构的分析表明,华南本地鸡种群表现出相当高的遗传多样性。此外,小白鸡和黄马鸡的商业路线表现出更高的遗传多样性水平,在聚类级别将它们与其他本地品种区分开来。然而,这些商业品种中的某些个体与本地种群表现出明显的遗传关系。值得注意的是,这两个商业品种也保留了显著程度的遗传相似性,他们各自的本地同行。为了研究本地鸡商业化过程中发生的基因组变化,我们采用了4种方法(FST,杆,XPCLR,和XPEHH)以确定在中国南方土鸡种群中显示选择性特征的潜在候选区域。共发现168个(由Fst和ROD鉴定)和86个(由XPCLR和XPEHH鉴定)重叠基因。功能注释分析显示这些基因可能与繁殖和生长有关(SAMSN1,HYLS1,ROBO3,FGF14,PRSS23),肌肉骨骼发育(DNER,MYBPC1,DGKB,ORC1,KLF10),抗病性和环境适应性(PUS3,CRB2,CALD1,USP15,SGCD,LTBP1),以及鸡蛋生产(ADGRB3,ACSF3)。总的来说,与商品鸡相比,华南地区的土鸡拥有许多选择性扫掠区域,为今后的遗传研究和育种保护丰富宝贵的基因组资源。
    The introduction of exotic breeds and the cultivation of new lines by breeding companies have posed challenges to native chickens in South China, including loss of breed characteristics, decreased genetic diversity, and declining purity. Understanding the population genetic structure and genetic diversity of native chickens in South China is crucial for further advancements in breeding efforts. In this study, we analyzed the population genetic structure and genetic diversity of 321 individuals from 10 different breeds in South China. By comparing commercial chickens with native ones, we identified selection signatures occurring between local chickens and commercial breeds. The analysis of population genetic structure revealed that the native chicken populations in South China exhibited a considerable level of genetic diversity. Moreover, the commercial lines of Xiaobai chicken and Huangma chicken displayed even higher levels of genetic diversity, which distinguished them from other native varieties at the clustering level. However, certain individuals within these commercial varieties showed a discernible genetic relationship with the native populations. Notably, both commercial varieties also retained a significant degree of genetic similarity to their respective native counterparts. In order to investigate the genomic changes occurring during the commercialization of native chickens, we employed 4 methods (Fst, ROD, XPCLR, and XPEHH) to identify potential candidate regions displaying selective signatures in Southern Chinese native chicken population. A total of 168 (identified by Fst and ROD) and 86 (identified by XPCLR and XPEHH) overlapping genes were discovered. Functional annotation analysis revealed that these genes may be associated with reproduction and growth (SAMSN1, HYLS1, ROBO3, FGF14, PRSS23), musculoskeletal development (DNER, MYBPC1, DGKB, ORC1, KLF10), disease resistance and environmental adaptability (PUS3, CRB2, CALD1, USP15, SGCD, LTBP1), as well as egg production (ADGRB3, ACSF3). Overall, native chickens in South China harbor numerous selective sweep regions compared to commercial chickens, enriching valuable genomic resources for future genetic research and breeding conservation.

    背景技术固态电池通常被认为是能量存储技术中即将到来的演进。这些可再充电电池的最新进展已经显著地加速了它们朝向实现商业可行性的轨迹。特别是,全固态锂硫电池(ASSLSB)依赖于锂硫可逆氧化还原过程显示出巨大的潜力,作为一个能量存储系统,超越传统的锂离子电池。这主要归因于它们异常的能量密度,延长运行寿命,并提高了安全属性。尽管有这些优势,ASSLSB在商业部门的采用一直很缓慢。为了加快这一特定领域的研究和开发,本文全面回顾了ASSLSB的现状。我们深入研究了向ASSLSB过渡的基本原理,探索所涉及的基本科学原理,并对ASSLSB面临的主要挑战进行全面评估。我们建议,该领域的未来研究应优先考虑非活性物质的存在,采用具有最佳性能的电极,最小化界面阻力,并设计可扩展的制造方法,以促进ASSLSB的商业化。
    Solid-state batteries are commonly acknowledged as the forthcoming evolution in energy storage technologies. Recent development progress for these rechargeable batteries has notably accelerated their trajectory toward achieving commercial feasibility. In particular, all-solid-state lithium-sulfur batteries (ASSLSBs) that rely on lithium-sulfur reversible redox processes exhibit immense potential as an energy storage system, surpassing conventional lithium-ion batteries. This can be attributed predominantly to their exceptional energy density, extended operational lifespan, and heightened safety attributes. Despite these advantages, the adoption of ASSLSBs in the commercial sector has been sluggish. To expedite research and development in this particular area, this article provides a thorough review of the current state of ASSLSBs. We delve into an in-depth analysis of the rationale behind transitioning to ASSLSBs, explore the fundamental scientific principles involved, and provide a comprehensive evaluation of the main challenges faced by ASSLSBs. We suggest that future research in this field should prioritize plummeting the presence of inactive substances, adopting electrodes with optimum performance, minimizing interfacial resistance, and designing a scalable fabrication approach to facilitate the commercialization of ASSLSBs.

    随着合成生物学的迅速发展,各种应用领域的许多合成生物学技术成果已经商业化,产生广阔的市场前景。采用合成生物学技术的产品(以下简称合成生物学产品)的商业化为人类带来了好处,但也产生了潜在的安全隐患。目前,通过了生物技术或转基因生物监管的相关法律和标准,以规范合成生物学产品(CSBP)商业化的安全风险。然而,由于合成生物学的复杂性和不确定性,CSBP的安全风险无法由这些法律和标准进行全面监管。因此,制定具体的监督管理措施对规范CSBP安全风险具有重要意义。本文综述了CSBP在食品领域的应用现状,医疗保健,农业,环境,能源和材料,分析了CSBP中存在的安全风险,并梳理了欧洲国家对其安全风险的监管现状,美国,以及在中国。并对CSBP安全风险的安全监督管理措施提出了建议,包括分类审批,产品的分类标识,在进入市场之前对市场主体进行严格的筛选和批准,加强进入市场后的安全监管和应急处理以及事故责任调查。该全过程安全法规可以为CSBP的安全性提供支持,并促进合成生物学产业的健康长期发展。
    With the rapid development of synthetic biology, lots of synthetic biology technology achievements in various application fields have been commercialized, generating broad market prospects. The commercialization of products employing synthetic biology technology (hereinafter referred as synthetic biology products) has brought benefits to human beings, but it has also produced potential safety risks. At present, relevant laws and standards for regulation of biotechnology or genetically modified organisms have been adopted to regulate the safety risks of commercialization of synthetic biology products (CSBP). However, due to the complexity and uncertainty of synthetic biology, the safety risks of CSBP cannot be comprehensively regulated by these laws and standards. Therefore, it is of great significance to formulate specific supervision and management measures for regulating the safety risks of CSBP. This paper summarized the situation of CSBP in the fields of food, medical care, agriculture, environment, energy and materials, analyzed the safety risks existing in the CSBP, and sorted out current supervision situation of its safety risks in European countries, United States, as well as in China. We further proposed suggestions on the safety supervision and management measures on the safety risks of CSBP, including classified examination and approval, classified identification of products, and strict screening and approval of market entities before entering the market, and strengthening safety supervision and emergency treatment as well as accident responsibility investigation after entering the market. This whole-process safety regulation might provide support for the safety of CSBP and promote the healthy and long-term development of synthetic biology industry.

    Perovskite (PVSK) photovoltaic (PV) devices are undergoing rapid development and have reached a certified power conversion efficiency (PCE) of 26.1% at the cell level. Tremendous efforts in material and device engineering have also increased moisture, heat, and light-related stability. Moreover, the solution-process nature makes the fabrication process of perovskite photovoltaic devices feasible and compatible with some mature high-volume manufacturing techniques. All these features render perovskite solar modules (PSMs) suitable for terawatt-scale energy production with a low levelized cost of electricity (LCOE). In this review, the current status of perovskite solar cells (PSCs) and modules and their potential applications are first introduced. Then critical challenges are identified in their commercialization and propose the corresponding solutions, including developing strategies to realize high-quality films over a large area to further improve power conversion efficiency and stability to meet the commercial demands. Finally, some potential development directions and issues requiring attention in the future, mainly focusing on further dealing with toxicity and recycling of the whole device, and the attainment of highly efficient perovskite-based tandem modules, which can reduce the environmental impact and accelerate the LCOE reduction are put forwarded.
