Supporting Early Career Researchers at the University of Bristol

布里斯托大学（UoB）选择支持工程，科学和生命科学学院的EPSRC职权范围内的一系列设备，支持五所学校的早期职业研究人员（ECR）。中红外多元素探测器系统将在UoB建立世界领先的能力，用于研究先进材料和生物分子中的超快能量流和电荷传输。结合现有的飞秒激光器，所产生的仪器将是美国以外的第一台此类仪器，也是世界上第二台此类光谱仪，使英国在时间分辨光谱学的前沿具有强大的竞争优势。与室外空气质量相比，室内空气质量的研究相对不足，尽管人类在室内花费了高达80%的时间。扫描迁移率粒度分析仪将使布里斯托气溶胶研究中心更有能力探索直径小于1微米的气溶胶粒子的特性，促进新的多学科研究伙伴关系。这一解决方案可以更好地管理哮喘，并解决睡眠和空气质量之间的关系。有机电化学与工业界和学术界的合成密切相关，因为该技术在进行可持续氧化还原反应方面具有众多优势，这是未来可持续和自动化化学合成的关键驱动力。12通道M204 Autolab可以同时进行电化学分析和电解反应实验，能够同时运行12个实验，并可容纳3个并发用户。对每秒数千兆位数据速率、更快和更可靠的无线通信的无处不在的计算需求不断增长，加上可用的低频段无线电频谱短缺，以满足这些需求，正在推动工业界和学术界将毫米波（mmWave）频谱作为5G及更高级别通信的一部分。这将为解决世界经济论坛预测的2030年500亿台互联设备提供一种变革性的方法。购买6 GHz以下和毫米波噪声和信号分析仪将为测量能力提供新的维度，同时在英国生态系统中建立一个面向未来的世界级实验室。复杂物体的物理3D打印模型极大地提高了对晶体研究等问题的理解，特别是晶体界面和晶体缺陷;在预定的3D结构中自组装的（生物）分子的设计;利用力学和几何学之间的相互作用，优化可展开空间结构的原型，重量/节能假肢和机器人多功能组件，与在屏幕上研究计算机可视化相比。许多空气动力学应用位于湍流状态（特别是考虑射流、边界层和尾流）内，因此，描述所观察到的流的所有参数都显示出随时间的变化。为了捕捉由于小的湍流结构的通过而引起的流速的时间变化，能够捕捉千赫兹量级波动的热线风速测量系统成为必要。微纤维和纳米纤维是突破性技术的基础，因为它们能够制造具有单独使用块体材料无法实现的功能的设备。薄膜和增强的洁净室沉积能力将使这些应用成为可能，例如在芯片实验室设备中制造微流体通道，用于快速抗微生物耐药性检测，用于单分子和量子光测量的等离子体纳米天线，以及能够“看到”单个原子的最精细的原子力显微镜探针。

The University of Bristol (UoB) has chosen to support a range of equipment across EPSRC's remit in the Engineering, Science and Life Sciences Faculties, supporting Early Career Researchers (ECRs) across five Schools. A mid-infrared multi-element detector system would establish a world-leading capability at UoB for the study of ultrafast energy flow and charge transport in advanced materials and biomolecules. Combined with an existing femtosecond laser, the resulting instrument will be the first of its kind outside the USA, and only the second such spectrometer in the world, giving the UK a strong competitive edge at the frontier of time-resolved optical spectroscopy. Indoor air quality is relatively understudied compared to outdoor air quality, despite humans spending up to 80% of their time indoors. A scanning mobility particle sizer would provide the Bristol Aerosol Research Centre with enhanced capability to explore the properties of aerosol particles below 1 micrometer diameter, catalysing new, multidisciplinary research partnerships. This resolution could lead to better management of asthma and resolving relationships between sleep and air quality.Organic electrochemistry is becoming immensely relevant to synthesis in both industry and academia because the technology boasts numerous advantages in its ability to perform sustainable redox reactions, a key driver for a future of sustainable and automated chemical synthesis. The 12-channel M204 Autolab can perform experiments for both electrochemical analysis and preparative-scale electrolysis reactions, with the ability to run 12 experiments simultaneously and accommodate 3 concurrent users.The ever-growing demand for ubiquitous computing for multi-gigabit-per-second data rates, faster, and more reliable wireless communications, together with the shortage of available low-band radio spectrum to address these needs, is pushing industry and the academic community to consider millimetre wave (mmWave) spectrum as a part of 5G and beyond communications. This will offer a transformative approach towards addressing the 50 billion interconnected devices forecasted by the World Economic Forum for the year 2030. The purchase of a Sub 6GHz and Millimetre Wave Noise and Signal Analyser will provide a new dimension to measurement capabilities whilst future-proofing a World-Class Lab in the UK ecosystem. Physical, 3D printed models of complex objects greatly improve understanding of problems such as the study of crystals, in particular crystal interfaces and crystal defects; the design of (bio-)molecules that self-assemble in a predetermined 3D structure; and exploit the interaction between mechanics and geometry and optimise prototypes for deployable space structures, weight/energy-efficient prosthetics and multifunctional components for robotics, compared to studying computer-visualisations on a screen. Many aerodynamic applications lie within the turbulent flow regime (especially considering jet, boundary layer and wake flows) and, as such, all parameters describing the observed flow show a variation in time. To capture temporal variation in flow velocity due to the passing of small turbulent structures, a hotwire anemometry system capable of capturing fluctuations in the order of kilo-Hertz becomes a necessity.Micro- and nanofabrication are the foundations of breakthrough technologies due to their ability to fabricate devices with functionality not available using bulk materials alone. Thin-films and augmenting cleanroom deposition capabilities will enable such applications as fabrication of microfluidic channels in lab-on-chip devices for fast antimicrobial resistance detection, plasmonic nanoantennas for single molecule and quantum light measurements, and the very finest atomic force microscopy probes that are capable of 'seeing' single atoms
