Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：On the Gauss maps of complete minimal surfaces in Rm
Rm 完全极小曲面 高斯映射
2023/12/11
We prove that if the Gauss map of a minimal surface immersed in Rm omits a generic hypersurface of large enough degree, then it must be constant.
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Kazdan-Warner equations on compact Riemann surfaces
紧黎曼曲面 卡兹丹-华纳方程 数学
2023/4/28
In this talk, we shall review firstly the study history of Kazdan-Warner equations on compact Riemann surfaces, which was proposed by Kazdan and Warner on Annals of Math on 1974. Then we shall show th...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Recent developments on random hyperbolic surfaces of large genus
大属随机 双曲曲面 球面几何
2023/4/21
In this talk, we report several very recent asymptotic results on certain classical geometric quantities viewed as random variables on the moduli space of Riemann surfaces for large genus (and many cu...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Bloch's conjecture for symplectic autoequivalences on K3 surfaces
布洛赫 K3曲面 辛自等价
2023/4/13
Bloch's conjecture for a surface X over an algebraically closed field k states that every homologically trivial correspondence acts as 0 on the Albanese kernel. When X is a K3 surface, this conjecture...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：On Kahler Ricci shrinker surfaces
Kahler Ricci 收缩机 表面
2023/4/23
We prove that any K?hler Ricci shrinker surface has bounded sectional curvature. Combining this estimate with earlier work by many authors, we provide a complete classification of all K?hler Ricci shr...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Large deviations in random interlacements II: tilted interlacements and solidification of porous surfaces
随机交错 大偏差 倾斜交错 多孔表面 固化
2023/5/10
In this lecture, I will discuss how tilting and coarse graining, two key ideas in modern probability, come into play in deriving respectively the lower and upper bounds of the asymptotic probability i...
The boiling of water or other fluids is an energy-intensive step at the heart of a wide range of industrial processes, including most electricity generating plants, many chemical production systems, a...
While brooms and sponges are the means of choice to fight contamination in everyday life, cleaning sensitive surfaces such as electronic components requires different tools, including evaporation-base...
The wettability of a surface — whether drops of water or another liquid bead up or spread out when they come into contact with it — is a crucial factor in a wide variety of commercial and industrial a...
Making catalytic surfaces more active to help decarbonize fuels and chemicals（图）
催化表面 帮助燃料 化学品脱碳
2023/6/7
Electrochemical reactions that are accelerated using catalysts lie at the heart of many processes for making and using fuels, chemicals, and materials — including storing electricity from renewable en...
When you’re frying something in a skillet and some droplets of water fall into the pan, you may have noticed those droplets skittering around on top of the film of hot oil. Now, that seemingly trivial...
Bacteria navigate on surfaces using a 'sense of touch'
pseudomonas aeruginosa cell inhibitors microbial
2021/8/6
Researchers have characterized a mechanism that allows bacteria to direct their movement in response to the mechanical properties of the surfaces the microbes move on -- a finding that could help figh...
Condensation heat transfer of steam on vertical dropwise and filmwise coexisting surfaces with a thick organic film promoting dropwise
蒸汽 滴状 膜状 DFC 冷凝传热
2023/3/1
This article describes an experimental investigation of the condensation heat transfer of steam on dropwise and filmwise coexisting (DFC) surfaces, on which dropwise and filmwise exist simultaneously ...
Effect of Morphology of Nano-Structured Surfaces on Anti-Icing Performance
nanowires superhydrophobic surface anti-icing impacting bouncing
2023/3/1
Droplets bouncing off cold surfaces before being frozen is one way to achieve anti-icing, in which process superhydrophobic surfaces have been proven to play an important role. By using template-assis...
近日，山西医科大学基础医学院生物化学与分子生物学教研室于保锋教授团队在《Colloids and Surfaces B: Biointerfaces》期刊上在线发表了题为“β-Cyclodextrin-cholic acid-hyaluronic acid polymer coated Fe3O4 -graphene oxide nanohybrids as local chemo-phototh...
