工业革命发生后,革命性的理论诞生于欧洲,这些理论是现代科学的基础。然而,近几十年来,我们观察到技术研究的前沿正在向世界其他地区转移。先进技术和高科技产业的进一步发展需要大量的智力、物质和金融资本,超出了许多欧洲中小型国家经济体的能力。欧洲保持领先地位,特别是在技术科学领域,一个不可或缺的条件是发展欧盟国家之间的科技和金融合作,建立国际研究团队,特别是在决定实现数字和能源转型目标的技术方面。在为期两天的 CETEF'24 会议期间,代表这些国家的政界人士、管理者、科学家和技术专家将讨论如何加强和提高欧洲科技合作的有效性,如何增加中东欧国家在其中的参与。我深信,CETEF'24 会议将为改善欧洲创新和研究发展计划的工具做出宝贵贡献,并将有助于扩大国际合作和建立许多个人联系。
第三阶段物理组件(上图 1(b))保留了第二阶段设计的许多成功特性(来自 [3],如图 1(a) 所示)。加热谐振单元组件由张紧聚酰亚胺“系绳”支撑,这些系绳在机械坚固的配置中提供非凡的热隔离(7000°C/W)。使用传统的光刻技术将谐振单元组件的电气连接以及加热器本身图案化到聚酰亚胺上,以便(导热、金属)迹线的尺寸由电气要求而非机械要求决定,从而最大限度地减少通过电子连接的热损失。共振腔本身由 Pyrex ® 窗口阳极键合到穿孔硅晶片制成,除了温度补偿缓冲气体混合物外,还含有少量金属铯,从第二阶段到第三阶段的演变过程中也没有变化。
泰国乃至全球的汽车行业正在从内燃机汽车 (ICE) 向电动汽车 (EV) 转型。这一转变受到外部因素的推动,例如新电动汽车制造商的出现、电动汽车的工程和设计变化,以及包括泰国在内的各国和泰国出口目的地国家对电动汽车的支持政策。泰国政府推出了 30@30 政策等举措,旨在到 2030 年电动汽车产量占汽车总产量的 30%。此外,泰国的税收政策于 2022 年公布,并于 2023 年批准了进一步支持电动汽车使用的措施,以刺激泰国电动汽车行业的持续扩张。这些政策包括降低消费税和进口税等。

Abstract The study of light at the nanoscale has become a vibrant field of research, as researchers now master the flow of light at length scales far below the optical wavelength, largely surpassing the classical limits imposed by diffraction. Using metallic and dielectric nanostructures precisely sculpted into 2D and 3D nanoarchitectures, light can be scattered, refracted, confined, filtered, and processed in fascinating new ways, impossible to achieve with natural materials and in conventional geometries. This control over light at the nanoscale has not only unveiled a plethora of new phenomena, but has also led to a variety of relevant applications, including new venues for integrated circuitry, optical computing, solar, and medical technologies, setting high expectations for many novel discoveries in the years to come. Introduction Optics and the science of light is a lively field of research that continues to surprise decade after decade with fundamental breakthroughs and disruptive applications. Communications technology has been revolutionized by the invention of the laser and the optical fiber, incandescent light bulbs are being replaced by efficient solid-state lighting, and solar energy technologies are on their way to price parity with fossil-fuel based power generation. A large number of these developments has resulted from increased control over the flow of light at length scales smaller than the wavelength. Squeezing light to nanoscale dimensions also opens the prospect of dense optical integrated circuits, which may overcome fundamental challenges related to bandwidth and energy dissipation in today's electronic integrated circuit technology. More broadly, the field of nanophotonics aims at overcoming Abbe's diffraction limit, developing technology able to manipulate light on a deep- subwavelength scale. As photons are shrunk to the nanometer scale, ultimately approaching the scale of the wave function of electrons, fundamental new science is expected, and important technological advances appear. In this article we review recent highlights in the science and applications of nanophotonics, focusing on the ultraviolet/visible/near-infrared spectral range, and provide an outlook for the bright future of this research field. Photonic crystals The initial concept for on-chip miniaturization of light dates back to the late 1990's, when photonic crystals – periodic structures fabricated from high refractive index materials like Si or GaAs – were proposed and realized (Fig. 1A). As the periodicity in these structures approaches the wavelength of light a photonic bandgap can appear, analogous to the energy bandgap in a semiconductor. The propagation of light with a frequency in the band gap is then forbidden, except in localized regions created by a well-designed break in periodicity, such as line defects that can guide light, or point defects that confine light. Band structure engineering gives exquisite control over light dispersion, i.e., over the relation between its frequency ω and its effective propagation constant k=2 π/λ, and thereby also over how fast signals of different wavelengths propagate, as given by the group velocity d ω /dk.
