Additive nanomanufacturing using nanoscale printing

关于上面概述的总体方向，该项目将首先探索不同的方法，以结合(I)电动流体-喷墨打印，(Ii)扫描探头和(Iii)纳米流体，如果适用，在表面上附加图案。我们讨论的方法之一是利用Cytosurge生产的探针来a)复制该公司在绘制液体图案方面的成功，以及b)将这项工作扩展到热和电驱动材料，并以液体或蒸发形式对它们进行图案制作。总的来说，该项目的目标是提出一系列纳米级的制造技术，使我们能够拥有能够蒸发打印材料的桌面设置，以及在实验室环境中轻松地蚀刻材料而不使用掩膜。其目标是大大简化目前依赖于光刻的纳米制造过程。虽然光刻是一种非常成功的工艺，但现在人们知道这些工艺对环境非常不友好(据估计，一个2克芯片需要1.6公斤的化石燃料才能生产出来)。因此，尽管很适合大规模生产相同的部件，但对于复杂的纳米设备来说，小批量部件的创新是不存在的。我们的目标是能够以较低的批次大小“定制”制造这类部件。这个项目将作为研究小组更大努力的一部分，为实现这一目标做出贡献。它还将培训DPhil学生掌握一系列高要求的技能，如光刻技术、器件设计和建模、纳米级表征、数据分析和报告撰写，以及独立设计和运行实验的能力。这与EPSRC的“本地化、定制化”战略非常一致。它还有能力让英国的小型设计公司真正测试原型设备，并通过价值链保留更多价值。作为H.Bhaskaran持有的更大EPSRC奖学金的一部分，潜在的合作者包括IBM、牛津仪器、MSolv、Bodle Technologies和巴斯夫，但也包括EPSRC资助的其他项目下的更大财团，如可穿戴和灵活技术联盟(waft，www.waftCollaboration.org)。这项研究与EPSRC的未来制造主题以及工程学和物理科学研究相一致。具有工程学背景的项目非常适合学生的技能，他们有机会以独特的创造性方式为这一令人兴奋的研究领域做出贡献。EPSRC的研究领域：工程信息和通信技术(ICT)制造未来物理科学研究基础设施

Regarding the general direction outlined above, the project will begin by exploring different approaches to combine (i) Electrohydrodynamic-Inkjet Printing, (ii) Scanning Probes and (iii) Nanofluidics, if applicable, to additively pattern on surfaces. One of the approaches we discussed is to utilize probes produced by cytosurge to a) Replicate the success the company has had in patterning liquids and b) to extend this work to both thermally and electrically actuate materials and pattern them in either liquid or evaporated form.Overall, the aims of this project are to come up with a range of manufacturing techniques at the nanoscale that will enable us to have desktop set-ups that can evaporatively print materials additively, as well as easily etch materials without use of a mask in a laboratory setting. The goal is to vastly simplify the nanofabrication process, which currently relies on lithography. Although lithography is a wildly successful process, it is now known that these processes are very environmentally unfriendly (with estimates for a 2 g chip requiring 1.6 kg of fossil fuels to produce by the UN). Therefore, although well suited to mass manufacturing identical components, innovation on smaller batches of components is non-existent for complex nanoscale devices. Our goal is to enable "bespoke" manufacturing of such components with lower batch sizes. This project will contribute towards that goal as part of a larger effort within the research group.It will also train the DPhil student in a range of the high demand skills such as lithography, device design and modeling, characterization at the nanoscale, data analysis and report writing as well as the ability to design and run experiments independently.This is well aligned to EPSRC's strategy of "Make it local, make it > bespoke". It also has the capability to let small design houses that UK has to really test prototype devices and retain more value through the value chain. Potential collaborators as part of the larger EPSRC Fellowship held by H. Bhaskaran include IBM, Oxford Instruments, MSolv, Bodle Technologies and BASF, but also much larger consortiums under other EPSRC funded projects such as the Wearable and Flexible Technologies Consortium (WAFT, www.waftcollaboration.org). This research is aligned to EPSRC's Manufacturing the future theme, as well as the Engineering and Physical Sciences remits. With a background in engineering, the projects fits very well to the skills of the student, who has the opportunity to contribute in a uniquely creative manner towards this exciting research area.EPSRC's research areas:EngineeringInformation and communication technologies (ICT)Manufacturing the futurePhysical sciencesResearch infrastructure
