By means of a variational approach, a statement on boundedness of the quantities $$ \\begin{eqnarray*} \\sup_{t\\in (0,T)} \\int_\\Omega \\big|\\nabla V(\\cdot,t)\\big|^p L^{\\frac{n+p}{n+2}} \\Big( \\big|\\nabla V(\\cdot,t)\\big| \\Big) \\end{eqnarray*}$$in dependence on the expressions (0.2)$$ \\begin{align}& \\sup_{t\\in (0,T-\\tau)} \\int_t^{t+\\tau} \\int_\\Omega |f|^{\\frac{(n+2)p}{n+p}} L\\big( |f|\\big) \\end{align}$$is derived for $p\\ge 2$, $\\tau&gt;0$, and $T\\ge 2\\tau $, provided that $L\\in C^0([0,\\infty ))$ is positive, strictly increasing, unbounded, and slowly growing in the sense that $\\limsup _{s\\to \\infty } \\frac {L(s^{\\lambda _0})}{L(s)} &lt;\\infty $ for some $\\lambda _0&gt;1$. In the particular case when $p=n\\ge 2$, an additional condition on growth of $L$, particularly satisfied by $L(\\xi ):=\\ln ^\\alpha (\\xi +b)$ whenever $b&gt;0$ and $\\alpha&gt;\\frac {(n+2)(n-1)}{2n}$, is identified as sufficient to ensure that as a consequence of the above, bounds for theintegrals in (0.2) even imply estimates for the spatio-temporal modulus of continuity of solutions to (0.1). A subsequent application to the Keller–Segel system $$ \\begin{eqnarray*} \\left\\{ \\begin{array}{l} u_t = \\nabla \\cdot \\big( D(v)\\nabla u\\big) - \\nabla \\cdot \\big( uS(v)\\nabla v\\big) + ru - \\mu u^2, \\\\[1mm] v_t = \\Delta v-v+u, \\end{array} \\right. \\end{eqnarray*}$$shows that when $n=2$, $r\\in {\\mathbb {R}}$, $0&lt;D\\in C^2([0,\\infty ))$, and $S\\in C^2([0,\\infty )) \\cap W^{1,\\infty }((0,\\infty ))$ and thus especially in the presence of arbitrarily strong diffusion degeneracies implied by rapid decay of $D$, any choice of $\\mu&gt;0$ excludes blowup in the sense that for all suitably regular nonnegative initial data, an associated initial-boundary value problem admits a global bounded classical solution."}],"status":"public","_id":"63278","user_id":"31496","language":[{"iso":"eng"}],"publication_identifier":{"issn":["1073-7928","1687-0247"]},"publication_status":"published","issue":"19","year":"2022","page":"16336-16393","intvolume":" 2023","citation":{"ieee":"M.

In particular, graphitic carbon nitride g‐C3N4 has been investigated extensively in the past decade. However, the family of carbon nitrides is not limited to C3N4 and new CXNY are now being explored due to their different bandgap energy, morphology, and overall physicochemical properties. Here, homogenous and semi‐transparent C1N1 thin films are fabricated using guanine as a nontoxic molecular precursor. They are synthesized in a simplified chemical vapor deposition process on top of fused silica and fluorine doped tin oxide coated glass substrates. The chemical and structural studies reveal that C/N ratio is close to target 1, triazine vibrations are visible in vibrational spectra and stacking of the film is observed from glancing incidence X‐ray diffraction data. The (photo)electrochemical properties are studied, the film is a p‐type semiconductor with a good photoresponse to visible light and a suitable catalyst for hydrogen evolution reaction. A simple and safe way of synthesizing C1N1 films on a range of substrates is presented here.","lang":"eng"}],"user_id":"98120","_id":"62676","language":[{"iso":"eng"}],"article_number":"2202061","issue":"6","publication_identifier":{"issn":["2196-7350","2196-7350"]},"publication_status":"published","intvolume":" 10","citation":{"bibtex":"@article{Jerigová_Heske_Kühne_Tian_Tovar_Odziomek_Lopez Salas_2022, title={C1N1 Thin Films from Guanine Decomposition Fragments}, volume={10}, DOI={10.1002/admi.202202061}, number={62202061}, journal={Advanced Materials Interfaces}, publisher={Wiley}, author={Jerigová, Mária and Heske, Julian and Kühne, ThomasD. and Tian, Zhihong and Tovar, Michael and Odziomek, Mateusz and Lopez Salas, Nieves}, year={2022} }","short":"M.

In this contribution, the notion of a driven Gaussian quantum walk is introduced. In contrast to typically considered quantum walks in optical settings, we describe the operation of the walk in terms of a nonlinear map rather than a unitary operation, e.g., by replacing a beam-splitter-type coin with a two-mode squeezer, being a process that is controlled and driven by a pump field. This opens previously unattainable possibilities for quantum walks that include nonlinear elements as core components of their operation, vastly extending their range of applications. A full framework for driven Gaussian quantum walks is developed, including methods to dynamically characterize nonlinear, quantum, and quantum-nonlinear effects. Moreover, driven Gaussian quantum walks are compared with their classically interfering and linear counterparts, which are based on classical coherence of light rather than quantum superpositions. In particular, the generation and boost of highly multimode entanglement, squeezing, and other quantum effects are studied over the duration of the nonlinear walk. Importantly, we prove the quantumness of the evolution itself, regardless of the input state. A scheme for an experimental realization is proposed. Furthermore, nonlinear properties of driven Gaussian quantum walks are explored, such as amplification that leads to an ever increasing number of correlated quantum particles, constituting a source of new walkers during the walk. Therefore, a concept for quantum walks is proposed that leads to—and even produces—directly accessible quantum phenomena, and that renders the quantum simulation of nonlinear processes possible.","lang":"eng"}],"author":[{"first_name":"Philip","full_name":"Held, Philip","id":"68236","last_name":"Held"},{"full_name":"Engelkemeier, Melanie","last_name":"Engelkemeier","first_name":"Melanie"},{"full_name":"De, Syamsundar","last_name":"De","first_name":"Syamsundar"},{"id":"48188","full_name":"Barkhofen, Sonja","last_name":"Barkhofen","first_name":"Sonja"},{"first_name":"Jan","orcid":"0000-0002-5844-3205","last_name":"Sperling","id":"75127","full_name":"Sperling, Jan"},{"id":"26263","full_name":"Silberhorn, Christine","last_name":"Silberhorn","first_name":"Christine"}],"volume":105,"date_updated":"2026-01-09T09:50:22Z","main_file_link":[{"url":"https://journals.aps.org/pra/abstract/10.1103/PhysRevA.105.042210"}],"doi":"10.1103/physreva.105.042210","publication_status":"published","publication_identifier":{"issn":["2469-9926","2469-9934"]},"citation":{"apa":"Held, P., Engelkemeier, M., De, S., Barkhofen, S., Sperling, J., & Silberhorn, C.
