The impact on environment and on human health of different pollutants produced par human activities including energy production, especially chemical pollutants, is becoming critical due to their drastic consequences on our main vital resources: water and air. In recent years, extensive efforts of fundamental research and developing practical processes have been devoted to the green energy production and to the polluted water air treatment. ZnO, as a multifunctional semiconductor, has been widely studied since 20 years for its piezoelectric nanogeneration for microelectronic device power suppling. On the other hand, the semiconductor-based photocatalytic process has shown a great potential as an environmental-friendly and sustainable treatment technology by using solar energy. Among the photocatalytic materials, nanostructured ZnO is a promising candidate for its high surface/volume ratio, its easy-controllable low cost synthesis, and its chemical thermal stability. The ability of ZnO based photocatalysis technology has been widely demonstrated to remove persistent organic compounds (such as dyes, antibiotics, microorganisms) in water, and toxic gases (such as NOx, COVs, ) in air; and its photocatalytic efficiency can be enhanced by transition metal doping process. ZnO nanostructures can also be synthesized on civil engineering materials for self-cleaning road application to avoid the soil pollution. 现今世界面对两个紧密亲密相干的严重问题：能源欠缺和情况污染。人类勾当发生的分歧污染物对情况和人类健康的影响，特别是能源出产中的化学污染物，正在变得相当主要，由于它们对我们的首要生命资本：水和空气发生了严重的后果。最近几年来，年夜量的根本研究和开辟适用进程的尽力都投入到了绿色能源出产和污染水和空气处置中。作为多功能半导体的氧化锌（ZnO），因其压电纳米发电能力，为微电子装备供电，自20年前以来已被普遍研究。另外一方面，基在半导体的光催化进程显示出作为情况友爱和可延续处置手艺的庞大潜力，它操纵太阳能。在光催化材猜中，纳米布局的氧化锌因其高比概况积、易在节制和低本钱的合成和化学和热不变性而成为一个有但愿的候选材料。基在氧化锌的光催化手艺已被普遍证实可以或许去除水中的持久性有机化合物（如染料、抗生素和微生物）和空气中的有毒气体（如NOx、COVs等）；其光催化效力可以经由过程过渡金属搀杂进程来提高。氧化锌纳米布局也能够合成在土木匠程材料上，用在自洁净道路利用，以免泥土污染。 [BIOGRAPHY] Yamin Leprince-Wang is Full Professor (Exceptional Class) at the Gustave Eiffel University (UGE), France, where she is Head of the Materials Science Engineering Master s degree course.

The performance of these reactors relies heavily on hydrodynamics and gas/liquid mass transfer. Typically, GLS reactors, often containing packing particles, confine rising bubbles to illustrate various physical phenomena that significantly influence hydrodynamics and can potentially enhance mass transfer performance. The presence of solid packing particles in these reactors leads to greater bubble deformation, extended rising residence time, and a thinner liquid film, all of which accelerate gas-liquid mass transfer. In this iCANX talk, I propose to present how to experimentally quantify the contribution of the near solid surface by investigating bubble/solid surface contact from a multi-scale perspective and its impact on hydrodynamics and gas-liquid mass transfer. What are the new methods for mass transfer quantification at the local scale, and how can controlling bubble/solid interactions optimize the performance of Gas/Liquid/Solid reactors? 气/液/固（GLS）反映器在化学和工业进程的成长中阐扬了要害感化。这些反映器的机能在很年夜水平上依靠在流体动力学和蔼/液质量传递。凡是，GLS反映器中经常含有填充颗粒，这些颗粒限制了上升气泡的活动，以展现各类显著影响流体动力学的物理现象，并可能加强质量传递机能。在这些反映器中存在固体填充颗粒，会致使气泡变形更年夜、上升逗留时候耽误和液体膜更薄，所有这些都加快了气-液质量传递。在此次iCANX演讲中，我提议展现若何经由过程从多标准角度研究气泡/固体概况接触来尝试量化近固体概况的进献和其对流体动力学和蔼-液质量传递的影响。在局部标准上，有哪些新的方式可以量化质量传递，和若何经由过程节制气泡/固体彼此感化来优化气/液/固反映器的机能？ [BIOGRAPHY] Abderrahmane Kherbeche is an Associate Professor in Process Engineering applied to the Environment at Gustave Eiffel University since September 2020.
