This study investigates how gravitational modulation influences bio-convective heat and mass transfer in porous materials saturated with motile microorganisms under reactive flow conditions. The main aim is to develop a comprehensive multiscale model that couples thermal, solutal, microbial, and gravitational processes with chemical reactions. The governing equations are formulated using Darcy–Brinkman and energy transport relations, incorporating activation energy, cross-diffusion effects, and microbial motility. Linear stability analysis is used to determine the critical Rayleigh–Darcy number marking the onset of convection, while weakly nonlinear analysis based on the Ginzburg–Landau equation is employed to capture amplitude evolution and post-onset transport dynamics. The results show that gravitational modulation lowers the critical threshold for instability, thereby promoting earlier onset of convection, while parameters, such as Darcy number, Lewis number, and activation energy, exert a stabilizing influence. Nonlinear analysis reveals that heat and mass transfer rates, represented by the Nusselt and Sherwood numbers, are significantly affected by modulation frequency, amplitude, and microbial activity, leading to either enhancement or suppression of convective transport. Overall, the findings highlight the dual role of gravitational modulation as both a destabilizing factor and a control mechanism, showing that higher modulation frequencies stabilize the system, while larger amplitudes promote earlier convection onset.</p><p>This study investigates how gravitational modulation influences bio-convective heat and mass transfer in porous media with motile microorganisms.

In our formulation, standard quantum mechanics itself emerges from first-order categorical coherence breakdown, corresponding to the familiar non-commutativity of observables and described geometrically by the Uhlmann gauge connection on the purification bundle. By promoting this to a higher categorical and higher gauge framework, we show that breakdown at higher coherence levels corresponds to the emergence of higher Uhlmann curvatures-geometric obstruction classes whose state-dependent structure induces intrinsic nonlinearities in the quantum equations of motion. We provide a concrete categorical model based on a 2-category of contexts generated by projective-valued measures (PVMs) with coarse-grainings, construct the Uhlmann bundle-gerbe over the manifold of full-rank density operators, and compute its Deligne class. A rigorous transgression functor from the path 2-groupoid of contexts to the holonomy 2-group of the gerbe yields curvature-weighted Magnus/Chen expansions, from which we derive explicit nonlinear correction functionals <span>(mathcal {N}_{j}[rho ])</span> for æ =2,3. These nonlinear terms are the direct quantum-mechanical analog of interaction terms in gauge field theory, but arise here from multi-way measurement incompatibilities rather than external interactions. We argue that this higher-order geometric structure provides a natural theoretical framework for regimes where standard linear quantum mechanics is insufficient-particularly in quantum chemistry, multi-electron strongly correlated systems, and nonadiabatic dynamics at conical intersections. Applications are discussed for catalytic processes, chaotic electron dynamics, and materials with strong electron correlation, where our theory predicts experimentally testable deviations from linear quantum predictions.</p>","PeriodicalId":787,"journal":{"name":"The European Physical Journal B","volume":"98 10","pages":""},"PeriodicalIF":1.7,"publicationDate":"2025-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145256178","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A recent experiment on reduced graphene oxide (r-GO) inferred that polymerization of r-GO is necessary to discriminate various volatile organic compounds (VOC), the markers for detecting stage of degradation of food products. Motivated by this, using a combination of density functional theory and non-equilibrium Green’s function, we have investigated in detail the capability of monolayer graphene, r-GO and GO as sensors to detect quality of standard food products like vegetable, fruit, and meat. We assess the sensitivity and selectivity of these 2D materials as chemiresistive as well as work function-based sensors. We find that pristine graphene performs poorly while r-GO is able to differentiate between four, out of six VOCs (acetone, dimethylsulfide, ethanol, methanol, methylacetate, toluene), both as chemiresistive and work function-based sensor. GO, on the other hand, performs at par with r-GO as work function-based sensor but is not useful as chemiresistive one. We show that such behavior can be traced back to the changes in the electronic structures of the 2D materials upon adsorption of the VOCs. We infer that the discrepancy between our results and the experiment in the context of the performance of r-GO sensor can be due to the limitations in the experimental method of reducing Graphene.</p>","PeriodicalId":787,"journal":{"name":"The European Physical Journal B","volume":"98 10","pages":""},"PeriodicalIF":1.7,"publicationDate":"2025-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145256390","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
