We recently demonstrated the hierarchical self-assembly of phoretic microswimmers into self-spinning microgears and their synchronization by diffusiophoretic interactions [Aubret et al., Nat. Phys., 2018]. In this paper, we adopt a pedagogical approach and expose our strategy to control self-assembly and build machines using phoretic phenomena. We notably introduce Highly Inclined Laminated Optical sheets microscopy (HILO) to image and characterize anisotropic and dynamic diffusiophoretic interactions, which cannot be performed by conventional fluorescence microscopy. The dynamics of a (haematite) photocatalytic material immersed in (hydrogen peroxide) fuel under various illumination patterns is first described and quantitatively rationalized by a model of diffusiophoresis, the migration of a colloidal particle in a concentration gradient. It is further exploited to design phototactic microswimmers that direct towards the high intensity of light, as a result of the reorientation of the haematite in a light gradient. We finally show the assembly of self-spinning microgears from colloidal microswimmers and carefully characterize the interactions using HILO techniques. The results are compared with analytical and numerical predictions and agree quantitatively, stressing the important role played by concentration gradients induced by chemical activity to control and design interactions. Because the approach described hereby is generic, this works paves the way for the rational design of machines by controlling phoretic phenomena."}],"oa_version":"Preprint","pmid":1,"main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1909.11121"}],"scopus_import":"1","intvolume":" 14","month":"12","date_updated":"2023-02-23T13:47:43Z","extern":"1","_id":"9053","article_type":"original","type":"journal_article","keyword":["General Chemistry","Condensed Matter Physics"],"status":"public"},{"day":"01","publication":"Climate Dynamics","year":"2018","doi":"10.1007/s00382-016-3083-x","date_published":"2018-08-01T00:00:00Z","date_created":"2021-02-15T14:18:53Z","page":"1237-1257","publisher":"Springer Nature","quality_controlled":"1","oa":1,"user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","citation":{"chicago":"Drobinski, Philippe, Nicolas Da Silva, Gérémy Panthou, Sophie Bastin, Caroline J Muller, Bodo Ahrens, Marco Borga, et al. “Scaling Precipitation Extremes with Temperature in the Mediterranean: Past Climate Assessment and Projection in Anthropogenic Scenarios.” Climate Dynamics.

Over the 1979–2008 period, despite differences in quantitative precipitation simulation across the various models, the change in precipitation extremes with respect to temperature is robust and consistent. The spatial variability of the temperature–precipitation extremes relationship displays a hook shape across the Mediterranean, with negative slope at high temperatures and a slope following Clausius–Clapeyron (CC)-scaling at low temperatures. The temperature at which the slope of the temperature–precipitation extreme relation sharply changes (or temperature break), ranges from about 20 °C in the western Mediterranean to <10 °C in Greece. In addition, this slope is always negative in the arid regions of the Mediterranean. The scaling of the simulated precipitation extremes is insensitive to ocean–atmosphere coupling, while it depends very weakly on the resolution at high temperatures for short precipitation accumulation times. In future climate scenario simulations covering the 2070–2100 period, the temperature break shifts to higher temperatures by a value which is on average the mean regional temperature change due to global warming. The slope of the simulated future temperature–precipitation extremes relationship is close to CC-scaling at temperatures below the temperature break, while at high temperatures, the negative slope is close, but somewhat flatter or steeper, than in the current climate depending on the model. Overall, models predict more intense precipitation extremes in the future. Adjusting the temperature–precipitation extremes relationship in the present climate using the CC law and the temperature shift in the future allows the recovery of the temperature–precipitation extremes relationship in the future climate. This implies negligible regional changes of relative humidity in the future despite the large warming and drying over the Mediterranean. This suggests that the Mediterranean Sea is the primary source of moisture which counteracts the drying and warming impacts on relative humidity in parts of the Mediterranean region."}],"month":"08","intvolume":" 51","main_file_link":[{"url":"https://doi.org/10.1007/s00382-016-3083-x","open_access":"1"}],"extern":"1","date_updated":"2022-01-24T12:40:40Z","_id":"9136","status":"public","keyword":["Atmospheric Science"],"article_type":"original","type":"journal_article"},{"article_type":"original","type":"journal_article","status":"public","_id":"9134","date_updated":"2022-01-24T12:39:03Z","extern":"1","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1029/2017JC013591"}],"month":"09","intvolume":" 123","abstract":[{"text":"Several studies have shown the existence of a critical latitude where the dissipation of internal tides is strongly enhanced. Internal tides are internal waves generated by barotropic tidal currents impinging rough topography at the seafloor. Their dissipation and concomitant diapycnal mixing are believed to be important for water masses and the large‐scale ocean circulation. The purpose of this study is to clarify the physical processes at the origin of this strong latitudinal dependence of tidal energy dissipation. We find that different mechanisms are involved equatorward and poleward of the critical latitude. Triadic resonant instabilities are responsible for the dissipation of internal tides equatorward of the critical latitude. In particular, a dominant triad involving the primary internal tide and near‐inertial waves is key. At the critical latitude, the peak of energy dissipation is explained by both increased instability growth rates, and smaller scales of secondary waves thus more prone to break and dissipate their energy. Surprisingly, poleward of the critical latitude, the generation of evanescent waves appears to be crucial. Triadic instabilities have been widely studied, but the transfer of energy to evanescent waves has received comparatively little attention. Our work suggests that the nonlinear transfer of energy from the internal tide to evanescent waves (corresponding to the 2f‐pump mechanism described by Young et al., 2008, https://doi.org/10.1017/S0022112008001742) is an efficient mechanism to dissipate internal tide energy near and poleward of the critical latitude. The theoretical results are confirmed in idealized high‐resolution numerical simulations of a barotropic M2 tide impinging sinusoidal topography in a linearly stratified fluid.","lang":"eng"}],"oa_version":"Published Version","issue":"9","volume":123,"publication_identifier":{"issn":["2169-9275"]},"publication_status":"published","language":[{"iso":"eng"}],"author":[{"last_name":"Richet","full_name":"Richet, O.","first_name":"O."},{"last_name":"Chomaz","full_name":"Chomaz, J.-M.","first_name":"J.-M."},{"first_name":"Caroline J","id":"f978ccb0-3f7f-11eb-b193-b0e2bd13182b","full_name":"Muller, Caroline J","orcid":"0000-0001-5836-5350","last_name":"Muller"}],"article_processing_charge":"No","title":"Internal tide dissipation at topography: Triadic resonant instability equatorward and evanescent waves poleward of the critical latitude","citation":{"ista":"Richet O, Chomaz J-M, Muller CJ. 2018.

This results in a state where a moist cloudy region with intense deep convection is surrounded by extremely dry subsiding air devoid of deep convection. Because of the idealized settings of the simulations where it was discovered, the relevance of self-aggregation to the real world is still debated. Here, we show that self-aggregation feedbacks play a leading-order role in the spontaneous genesis of tropical cyclones in cloud-resolving simulations. Those feedbacks accelerate the cyclogenesis process by a factor of 2, and the feedbacks contributing to the cyclone formation show qualitative and quantitative agreement with the self-aggregation process. Once the cyclone is formed, wind-induced surface heat exchange (WISHE) effects dominate, although we find that self-aggregation feedbacks have a small but nonnegligible contribution to the maintenance of the mature cyclone. Our results suggest that self-aggregation, and the framework developed for its study, can help shed more light into the physical processes leading to cyclogenesis and cyclone intensification. In particular, our results point out the importance of the longwave radiative cooling outside the cyclone."}],"month":"03","intvolume":" 115","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1073/pnas.1719967115"}],"language":[{"iso":"eng"}],"publication_identifier":{"issn":["0027-8424","1091-6490"]},"publication_status":"published","volume":115,"issue":"12","user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","citation":{"mla":"Muller, Caroline J., and David M.

Targets of DME-mediated DNA demethylation reside in small, euchromatic, AT-rich transposons and at the boundaries of large transposons, but how DME interacts with these diverse chromatin states is unknown. The STRUCTURE SPECIFIC RECOGNITION PROTEIN 1 (SSRP1) subunit of the chromatin remodeler FACT (facilitates chromatin transactions), was previously shown to be involved in the DME-dependent regulation of genomic imprinting in Arabidopsis endosperm. Therefore, to investigate the interaction between DME and chromatin, we focused on the activity of the two FACT subunits, SSRP1 and SUPPRESSOR of TY16 (SPT16), during reproduction in Arabidopsis. We found that FACT colocalizes with nuclear DME in vivo, and that DME has two classes of target sites, the first being euchromatic and accessible to DME, but the second, representing over half of DME targets, requiring the action of FACT for DME-mediated DNA demethylation genome-wide. Our results show that the FACT-dependent DME targets are GC-rich heterochromatin domains with high nucleosome occupancy enriched with H3K9me2 and H3K27me1. Further, we demonstrate that heterochromatin-associated linker histone H1 specifically mediates the requirement for FACT at a subset of DME-target loci. Overall, our results demonstrate that FACT is required for DME targeting by facilitating its access to heterochromatin.","lang":"eng"}],"pmid":1,"oa_version":"Published Version","license":"https://creativecommons.org/licenses/by-nc-nd/4.0/","related_material":{"link":[{"relation":"earlier_version","url":"https://doi.org/10.1101/187674 "}]},"volume":115,"issue":"20","publication_status":"published","publication_identifier":{"eissn":["1091-6490"],"issn":["0027-8424"]},"language":[{"iso":"eng"}],"file":[{"relation":"main_file","access_level":"open_access","content_type":"application/pdf","success":1,"file_id":"9472","checksum":"810260dc0e3cc3033e15c19ad0dc123e","creator":"asandaue","file_size":3045260,"date_updated":"2021-06-07T06:16:38Z","file_name":"2018_PNAS_Frost.pdf","date_created":"2021-06-07T06:16:38Z"}],"tmp":{"short":"CC BY-NC-ND (4.0)","name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode","image":"/images/cc_by_nc_nd.png"},"type":"journal_article","article_type":"original","keyword":["Multidisciplinary"],"status":"public","_id":"9471","file_date_updated":"2021-06-07T06:16:38Z","department":[{"_id":"DaZi"}],"date_updated":"2021-12-14T07:53:40Z","ddc":["580"],"extern":"1","oa":1,"publisher":"National Academy of Sciences","quality_controlled":"1","page":"E4720-E4729","date_created":"2021-06-07T06:11:28Z","date_published":"2018-05-15T00:00:00Z","doi":"10.1073/pnas.1713333115","year":"2018","has_accepted_license":"1","publication":"Proceedings of the National Academy of Sciences","day":"15","external_id":{"pmid":["29712855"]},"article_processing_charge":"No","author":[{"first_name":"Jennifer M.","full_name":"Frost, Jennifer M.","last_name":"Frost"},{"first_name":"M.

However, even basic aspects of how fine particles become charged are still unclear. Studying particle charging is challenging because it usually involves the complexities associated with many-particle collisions. To address these issues, we introduce a method based on acoustic levitation, which makes it possible to initiate sequences of repeated collisions of a single submillimeter particle with a flat plate, and to precisely measure the particle charge in situ after each collision. We show that collisional charge transfer between insulators is dependent on the hydrophobicity of the contacting surfaces. We use glass, which we modify by attaching nonpolar molecules to the particle, the plate, or both. We find that hydrophilic surfaces develop significant positive charges after contacting hydrophobic surfaces. Moreover, we demonstrate that charging between a hydrophilic and a hydrophobic surface is suppressed in an acidic environment and enhanced in a basic one. Application of an electric field during each collision is found to modify the charge transfer, again depending on surface hydrophobicity. We discuss these results within the context of contact charging due to ion transfer, and we show that they lend strong support to OH− ions as the charge carriers."}],"oa_version":"Preprint","doi":"10.1103/PhysRevMaterials.2.035602","date_published":"2018-03-29T00:00:00Z","issue":"3","volume":2,"date_created":"2018-12-11T11:44:36Z","publication_status":"published","year":"2018","day":"29","publication":"Physical Review Materials","language":[{"iso":"eng"}]}]
