During this afternoon, you will work on hands-on exercises in Fiji for everyday tasks such as building your own macros, opening large datasets and image display tricks. More advanced topics, such as how to perform curve fitting, plotting line profiles, reslicing your data and batch processing, are also included.
\r\n
\r\nPlease feel free to suggest extra topics when you register. Depending on the replies, this will tailor the end of the day with some practicals ( for example : Colocalization, Tracking with Trackmate or cell detection with StarDist or Cellpose in Fiji ... )
\r\nWhile the course is of general use, the examples and applications are primarily relevant for those using light microscopy techniques.\r\n
Recent reports claim that hydrogen peroxide (H2O2) is spontaneously generated – without external energy input or catalyst – at the air–water interface of microdroplets1, bubbles2, and soap films3. Several mechanisms have been proposed to explain this phenomenon, including: (i) ultrahigh instantaneous electric fields at the air–water interface driving HO− à HO• + e− radicals from hydroxide ions; (ii) water’s comproportionation into H2O•+ and H2O•−; and (iii) partial dehydration of interfacial H+ and HO− followed by radical formation. In contrast, our laboratory experiments reveal that H2O2 formation is due to the reduction of dissolved O2 at water– solid interfaces, i.e., with no role for the air–water interface beyond O2 mass transport4-6. Based on these findings, I will present four diagnostic criteria against which any existing or future mechanistic proposal should be assessed. Our approach reconciles the claims of spontaneous H2O2 formation within established physical chemistry and extends naturally to other claims of anomalous microdroplet reactivity.

\r\nBio: Himanshu Mishra is a scientist-entrepreneur from King Abdullah University of Science and Technology (KAUST), Saudi Arabia. His team has significantly contributed to resolving scientific debates surrounding the spontaneous H2O2 formation in water microdroplets, the electrification at water-hydrophobe interfaces, and liquid–solid adhesion forces. Mishra’s team has also pioneered Carbosoil™ technology to transform desert soils for sustainable greening, food production, and carbon sequestration. His start-up Terraxy is now scaling up Carbosoil™ production to advance sustainability projects in the Middle East and beyond. Mishra’s efforts have been featured by the World Economic Forum, Geneva Inventions, and CNN (LINK).

Atomically precise carbon nanostructures offer a new route to quantum systems built from the bottom up. By combining molecular design, on-surface synthesis and scanning probe microscopy, we can control atomic structure, electronic states and magnetic interactions within the same platform.
\r\nIn this talk, I will follow the path from bottom-up synthesized graphene nanoribbons [1,2] to open-shell nanographenes [3] and designer quantum spin systems [4]. I will discuss how atomic structure can determine electronic topology and how molecular spins can be coupled into well-defined quantum chains. Recent examples include Haldane chains [4], alternating-exchange spin chains [5] and antiferromagnetic Heisenberg chains [6], where collective and fractional excitations can be probed directly at the atomic scale.
\r\nMore broadly, this work illustrates a materials-science strategy in which structure, functionality and interactions are programmed at the level of molecular building blocks. Rather than optimizing properties in an existing material, the aim is to design the material and its quantum behavior together. Atomically precise carbon nanostructures therefore provide a model platform for exploring how synthesis, structure and emergent functionality can be linked in a predictive way, with implications for the future design of low-dimensional electronic, magnetic and quantum materials.\r\n
Biological systems have already paved several routes for bioinspired materials, e.g., for structural colours, wetting, adhesion, and mechanical properties. They have largely involved equilibrium or kinetically trapped properties. By contrast, biological systems allowing multifunctional properties are characteristically dissipatively and dynamically adaptive and incorporate homeostatic feedback mechanisms to regulate the dynamic states. They also typically use signal transduction to mediate the signal from the sensory elements to the responsive sites, unlike the classic man-made stimuli responsive materials. These concept suggest avenues towards more complex life-like functions in soft matter. Herein, optically driven hydrogel systems are presented to drive homeostatically controlled thermal oscillations and to mediate signal transduction via thermal intermediate signalling (1). On the other hand, biological magnetoreception in elasmobranch organisms involves electromagnetic induction (EMI) and suggests avenues for bioinspired electrical signal transductions. We show magnetic profile recognition of translocated magnetically encoded soft matter objects using electrical intermediate signaling by EMI and decoding the magnetic information with machine learning (2). Combination of high stiffness and promoted dynamics for self-healing has turned challenging to combine. Self-healing hydrogels, still combining high tensile stiffness close to that of skin were shown by using polymers upon nanoconfinement in 2D-nanosheet layered confinements (3). Finally, we show trainable actuations in bilayer gel actuators (4). Ever more complex responses can be created, such as mimicking the Pavlovian classical conditioning (5), all paving ways for growingly life-like functions for soft robotics and interfacing with biology.

\r\nWhat to expect:\r\n
The brain forms a large recurrent spiking neural network with extremely high connectivity making time-dependent mean-field approaches valuable tools to translate the microscopic level of single-neuron dynamics to the mesoscopic or macroscopic level. In recent years, experimental data as well as simulation studies have highlighted the importance of low-dimensional macroscopic dynamics in large recurrent spiking networks. On the theory side, the notion of low-rank connectivity has shifted into the focus of interest.
\r\nThis meeting will to bring together researchers in mathematical and theoretical neuroscience who address the above topics from different perspectives.
