In this study, bioactive curcumin (CUM) derivatives were synthesized in a continuously operated microfluidic reactor (MFR), using piperidine-based polymeric networks as catalysts. Piperidine methacrylate and piperidine acrylate were synthesized and subsequently copolymerized with complementary monomers (MMA or DMAA) and crosslinkers (EGDMA or MBAM) via photopolymerization, yielding different polymeric networks. Initially, batch reactions were optimized for the organo-catalytic Knoevenagel condensation between CUM and 4-nitrobenzaldehyde, under various conditions, in the presence of polymer networks. Conversion was assessed using offline 1H NMR spectroscopy, revealing an increase in conversion with enhanced swelling properties of the polymer networks, which facilitated greater accessibility of catalytic sites. In continuous-flow MFR experiments, optimized polymer gel dots exhibited superior catalytic performance, achieving a conversion of up to 72%, compared to other compositions. This improvement was attributed to the enhanced swelling in the reaction mixture (DMSO/methanol, 7:3 v/v) at 40 °C over 72 h. Furthermore, the MFR system enabled the efficient synthesis of a series of CUM derivatives, demonstrating significantly higher conversion rates than traditional batch reactions. Notably, while batch reactions required 90% catalyst loading in the gel, the MFR system achieved a comparable or superior performance with only 50% catalyst, resulting in a higher turnover number. These findings underscore the advantages of continuous-flow organo-catalysis in enhancing catalytic efficiency and sustainability in organic synthesis. article_number: '278' author: - first_name: Naresh full_name: Killi, Naresh last_name: Killi - first_name: Katja full_name: Rumpke, Katja last_name: Rumpke - first_name: Dirk full_name: Kuckling, Dirk id: '287' last_name: Kuckling citation: ama: Killi N, Rumpke K, Kuckling D.

However, the challenge is to develop active polymers that exhibit an antimicrobial effect and are compatible with human cells. Different studies aiming for biocidal polymers active in soluble mode, focused on the ratio of cationic to hydrophobic groups, while only marginal knowledge is available for immobilized components. Here a strong hydrophilic electrolyte 4‐vinylbenzyltrimethylammonium chloride (TMA) is chosen as the cationic component. The block composition of the polycationic segment is modified with styrene (Sty) regarding the amphiphilic balance. To adsorb such polymers onto titanium surfaces they are equipped with a polyphosphonic acid anchor block by sequential reversible‐addition‐fragmentation chain‐transfer polymerization (RAFT) polymerization. The polymer composition affected the wetting behavior of adsorbed coatings with water contact angles ranging from 17° to 72°, while zetapotential measurements confirmed high extent of positive charges for all adsorbed polymer coatings. The fundamentally modified block composition resulted in significantly improved cytocompatibility. Antimicrobial efficacy in early bacterial adhesion is still retained from slightly antiadhesive coatings to combined antiadhesive/biocidal activity depending on Sty/TMA ratio in random polymers while a block copolymer revealed lowest antimicrobial effect. author: - first_name: Cornelia full_name: Wolf‐Brandstetter, Cornelia last_name: Wolf‐Brandstetter - first_name: Rafael full_name: Methling, Rafael last_name: Methling - first_name: Dirk full_name: Kuckling, Dirk id: '287' last_name: Kuckling citation: ama: Wolf‐Brandstetter C, Methling R, Kuckling D.

Lattice quality and assembly kinetics are controlled by various environmental parameters, including the employed surface, the assembly temperature, and the ionic composition of the buffer, with optimized parameter combinations resulting in highly ordered lattices that can span surface areas of several cm2. Established assembly protocols, however, employ assembly times ranging from hours to days. Here, the assembly of highly ordered hexagonal DNA origami lattices at mica surfaces is observed within few minutes using high-speed atomic force microscopy (HS-AFM). A moderate increase in the DNA origami concentration enables this rapid assembly. While forming a regular lattice takes 10 min at a DNA origami concentration of 4 nM, this time is shortened to about 2 min at a concentration of 6 nM. Increasing the DNA origami concentration any further does not result in shorter assembly times, presumably because DNA origami arrival at the mica surface is diffusion-limited. Over short length scales up to 1 µm, lattice order is independent of the DNA origami concentration. However, at larger length scales of a few microns, a DNA origami concentration of 10 nM yields slightly better order than lower and higher concentrations. Therefore, 10 nM can be considered the optimum concentration for the rapid assembly of highly ordered DNA origami lattices. These results thus represent an important step toward the industrial-scale application of DNA origami-based lithography masks." article_number: '77' author: - first_name: Bhanu Kiran full_name: Pothineni, Bhanu Kiran last_name: Pothineni - first_name: Jörg full_name: Barner, Jörg last_name: Barner - first_name: Guido full_name: Grundmeier, Guido id: '194' last_name: Grundmeier - first_name: David full_name: Contreras, David last_name: Contreras - first_name: Mario full_name: Castro, Mario last_name: Castro - first_name: Adrian full_name: Keller, Adrian id: '48864' last_name: Keller orcid: 0000-0001-7139-3110 citation: ama: Pothineni BK, Barner J, Grundmeier G, Contreras D, Castro M, Keller A.

However, silicon oxide surfaces come in many different forms and the type and history of the silicon oxide has a large effect on its physicochemical surface properties. Therefore, we here investigate DNA origami lattice formation on differently fabricated SiOx films on silicon wafers after wet-chemical oxidation by RCA1. Despite having similar oxide compositions and hydroxylation states, of all surfaces tested, only thermally grown SiOx performs similarly well as native oxide. For the other SiOx films deposited by plasma-enhanced chemical vapor deposition and magnetron sputtering, DNA origami adsorption is strongly suppressed. This is attributed to an increased surface roughness and a lower oxide density, respectively. Our results demonstrate that the employed SiOx surface may decide over the outcome of an experiment and should be considered as an additional parameter that may require optimization and fine-tuning before high-quality lattices can be assembled. In particular, our observations suggest that efficient DNA origami lattice assembly on SiOx surfaces requires a low surface roughness and a high oxide density. author: - first_name: Bhanu Kiran full_name: Pothineni, Bhanu Kiran last_name: Pothineni - first_name: Chantal full_name: Theile-Rasche, Chantal last_name: Theile-Rasche - first_name: Hendrik full_name: Müller, Hendrik last_name: Müller - first_name: Guido full_name: Grundmeier, Guido id: '194' last_name: Grundmeier - first_name: Maria Teresa full_name: de los Arcos de Pedro, Maria Teresa id: '54556' last_name: de los Arcos de Pedro orcid: '0000-0002-8684-273X ' - first_name: Adrian full_name: Keller, Adrian id: '48864' last_name: Keller orcid: 0000-0001-7139-3110 citation: ama: Pothineni BK, Theile-Rasche C, Müller H, Grundmeier G, de los Arcos de Pedro MT, Keller A.

However, rational materials development is hampered by difficulties in interpreting electrochemical impedance spectra (EIS) and drawing conclusions about promising aspects of device improvement. Here, we characterized electrodes consisting of activated carbon with polyacrylic acid binder in four different concentrations of sulfuric acid, using cyclic voltammetry and electrochemical impedance spectroscopy. Both datasets were evaluated with simple equivalent circuits and comparatively analyzed. Conductivity of the electrolyte was independently measured. Cyclic voltammograms (CV) show larger resistance and capacitance at low scan rates. Resistances obtained from EIS are in good agreement with those obtained by cyclic voltammograms particularly at high scan rates. The comparison against specific electrolyte resistance can reveal whether resistances within the solid electrode architecture or resistances within the electrolyte, partially confined by pores, are the dominant cause of increased resistance at low scan rate. Comparison between CV and EIS points to the main electrode capacitance being described by a constant phase element (CPE) used to fit the low-frequency region of EIS. author: - first_name: Sebastian full_name: Reinke, Sebastian id: '117727' last_name: Reinke - first_name: Vera full_name: Khamitsevich, Vera last_name: Khamitsevich - first_name: Julia full_name: Linnemann, Julia id: '116779' last_name: Linnemann orcid: 0000-0001-6883-5424 citation: ama: 'Reinke S, Khamitsevich V, Linnemann J.

Besides the original parameter sets, some specifically reparametrized SQC methods (denoted as AM1-W, PM6-fm, and DFTB2-iBi) targeting various smaller water systems ranging from molecular clusters to bulk are considered as well. The quality of these different SQC methods for describing liquid water properties at ambient conditions are assessed by comparison to well-established experimental data and also to BLYP-D3 density functional theory-based ab initio MD simulations. Our analyses reveal that static and dynamics properties of bulk water are poorly described by all considered SQC methods with the original parameters, regardless of the underlying theoretical models, with most of the methods suffering from too weak hydrogen bonds and hence predicting a far too fluid water with highly distorted hydrogen bond kinetics. On the other hand, the reparametrized force-matchcd PM6-fm method is shown to be able to quantitatively reproduce the static and dynamic features of liquid water, and thus can be used as a computationally efficient alternative to electronic structure-based MD simulations for liquid water that requires extended length and time scales. DFTB2-iBi predicts a slightly overstructured water with reduced fluidity, whereas AM1-W gives an amorphous ice-like structure for water at ambient conditions. author: - first_name: Xin full_name: Wu, Xin id: '77439' last_name: Wu - first_name: Hossam full_name: Elgabarty, Hossam id: '60250' last_name: Elgabarty orcid: 0000-0002-4945-1481 - first_name: Vahideh full_name: Alizadeh, Vahideh last_name: Alizadeh - first_name: Andres full_name: Henao Aristizabal, Andres id: '67235' last_name: Henao Aristizabal - first_name: Frederik full_name: Zysk, Frederik id: '14757' last_name: Zysk - first_name: Christian full_name: Plessl, Christian id: '16153' last_name: Plessl orcid: 0000-0001-5728-9982 - first_name: Sebastian full_name: Ehlert, Sebastian last_name: Ehlert - first_name: Jürg full_name: Hutter, Jürg last_name: Hutter - first_name: Thomas D. full_name: Kühne, Thomas D. id: '49079' last_name: Kühne citation: ama: Wu X, Elgabarty H, Alizadeh V, et al.

One of these challenges lies in the high strain-specificity of most bacteriophages, which makes it necessary to screen large phage collections against the target pathogens in order to identify suitable candidates for the formulations of personalized therapeutic phage cocktails. In this work, we evaluate the potential of quartz crystal microbalance with dissipation monitoring (QCM-D) to identify and detect phage infection and subsequent lysis of bacteria immobilized on the surfaces of the QCM-D sensors. Using lytic Escherichia coli phage T7 as a model, we show that phage infection of E. coli cells results in various unique alterations in the behaviors of the frequency (Δf) and dissipation (ΔD) signals, which are not observed during exposure of the E. coli strain to non-infectious Bacillus subtilis phage phi29 at similar concentration. To aid future phage screening campaigns, we furthermore identify a single measurement parameter, i.e., the spread between the different overtones of ΔD, that can be used to detect phage-induced lysis. For T7 infection of E. coli, this is achieved within 4 h after inoculation, including immobilization and growth of the bacteria on the sensor surface, as well as the completed phage propagation cycle. Given the commercial availability of highly automated multichannel systems and the fact that this approach does not require any sensor modifications, QCM-D has the potential to become a valuable tool for screening medium-sized phage collections against target pathogens.\r\n \r\n Graphical Abstract\r\n " author: - first_name: Bhanu K. full_name: Pothineni, Bhanu K. last_name: Pothineni - first_name: René full_name: Probst, René last_name: Probst - first_name: Dorothee full_name: Kiefer, Dorothee last_name: Kiefer - first_name: Verena full_name: Dobretzberger, Verena last_name: Dobretzberger - first_name: Ivan full_name: Barišić, Ivan last_name: Barišić - first_name: Guido full_name: Grundmeier, Guido id: '194' last_name: Grundmeier - first_name: Adrian full_name: Keller, Adrian id: '48864' last_name: Keller orcid: 0000-0001-7139-3110 citation: ama: Pothineni BK, Probst R, Kiefer D, et al.

In gas sensing, optical sensors are often used to detect gases such as CO, NOx, and O2. Oxygen sensors typically incorporate dyes into oxygen‐permeable matrices like polymers, silica, or zeolites. Alternatively, semiconductor surface chemistry can enable O2 detection. However, these approaches are often limited by slow response and recovery times and low selectivity, restricting their practical applications. The metal‐organic framework MOF‐76(Eu) and its yttrium‐modified variant, MOF‐76(Eu/Y) are reported to exhibit highly reversible and fast optical responses to varying O2 concentrations. Time‐resolved emission measurements are performed over short (seconds) and long (hours) timescales using N2 and synthetic air mixtures. Cross‐sensitivity to humidity is analyzed. Multichannel scaling photon‐counting experiments confirm quenching at the linker level, as the emission lifetime remains nearly constant. Yttrium significantly improves stability and performance at room temperature. Structural and optical changes induced by yttrium are investigated. Additionally, MIL‐78(Eu), another Eu‐BTC‐based MOF with a different coordination environment, is synthesized. Unlike MOF‐76(Eu), MIL‐78(Eu) exhibits distinct optical properties but lacks a reversible response to O2. These results highlight the potential of MOF‐76‐based materials for high‐performance O2 sensing. article_number: e11190 article_type: original author: - first_name: Zhenyu full_name: Zhao, Zhenyu last_name: Zhao - first_name: Christian full_name: Weinberger, Christian id: '11848' last_name: Weinberger - first_name: Jakob full_name: Steube, Jakob id: '40342' last_name: Steube orcid: 0000-0003-3178-4429 - first_name: Matthias full_name: Bauer, Matthias id: '47241' last_name: Bauer orcid: 0000-0002-9294-6076 - first_name: Martin full_name: Brehm, Martin id: '100167' last_name: Brehm - first_name: Michael full_name: Tiemann, Michael id: '23547' last_name: Tiemann orcid: 0000-0003-1711-2722 citation: ama: Zhao Z, Weinberger C, Steube J, Bauer M, Brehm M, Tiemann M.

To increase excited state lifetimes of iron complexes, the multichromophoric approach is promising, combining organic chromophores with photoactive iron complexes, potentially enabling a reservoir effect. We present a series of chromophore-functionalized complexes based on the parental FeIII complex [Fe(ImP)2][PF6] (HImP = 1,1′-(1,3-phenylene)bis(3-methyl-1-imidazole-2-ylidene)). The four organic chromophores benzene, naphthalene, anthracene, and pyrene are attached to the ImP-ligand in para-position to the coordination site to systematically investigate the influence of the steric demand and electronic properties of the chromophore on charge transfer lifetimes as well as photodynamics. A thorough ground state characterization was conducted in addition to investigations of the excited state dynamics by transient absorption spectroscopy and streak camera emission measurements. The conclusions drawn are supported by extensive DFT calculations. The emission coefficients could be significantly improved by the addition of chromophores. After excitation of the complexes with larger chromophores, coplanarization of the backbone and complex motif occurs to stabilize the formal charge. This results in population of a superligand state that exhibits a much faster radiationless relaxation to the ground state compared to the parent complex, hindering a reservoir effect. article_number: acs.inorgchem.5c00526 author: - first_name: Lennart full_name: Schmitz, Lennart id: '53140' last_name: Schmitz - first_name: Miguel A. full_name: Argüello Cordero, Miguel A. last_name: Argüello Cordero - first_name: Mohammed J. full_name: Al-Marri, Mohammed J. last_name: Al-Marri - first_name: Roland full_name: Schoch, Roland id: '48467' last_name: Schoch orcid: 0000-0003-2061-7289 - first_name: Hans full_name: Egold, Hans id: '101' last_name: Egold - first_name: Adam full_name: Neuba, Adam last_name: Neuba - first_name: Jakob full_name: Steube, Jakob id: '40342' last_name: Steube orcid: 0000-0003-3178-4429 - first_name: Bastian Johannes full_name: Bracht, Bastian Johannes id: '86707' last_name: Bracht - first_name: Olga S. full_name: Bokareva, Olga S. last_name: Bokareva - first_name: Stefan full_name: Lochbrunner, Stefan last_name: Lochbrunner - first_name: Matthias full_name: Bauer, Matthias id: '47241' last_name: Bauer orcid: 0000-0002-9294-6076 citation: ama: Schmitz L, Argüello Cordero MA, Al-Marri MJ, et al.

The influence of the strong donor ligand on the ground and excited-state photophysical properties was investigated in the context of different alkyl substituents at the imidazole nitrogen. X-ray diffraction revealed no significant alterations of the structures and all differences in the series emerge from the electronic structures. These were probed via cyclic voltammetry and UV–vis spectroscopy, detailing the influence of the different alkyl substituents on the ground-state properties. All complexes are emissive at 77 K from a 3MC state, which exhibits lifetimes in the range of 1–5 ns at room temperature, depending on the alkyl substituent. Therefore, it is clearly shown that even small differences in the electronic structure have a large impact on the details of the excited state landscape. The observed behavior was rationalized by a detailed DFT analysis, which shows that the minimum-energy crossing point to the ground-state is located only slightly above the MC energy: Consequently, nonradiative decay to the ground state at room temperature is enabled, while at 77 K this path is prohibited, leading to low-temperature 3MC emission.' author: - first_name: Athul full_name: Krishna, Athul last_name: Krishna - first_name: Lorena full_name: Fritsch, Lorena id: '44418' last_name: Fritsch - first_name: Jakob full_name: Steube, Jakob id: '40342' last_name: Steube orcid: 0000-0003-3178-4429 - first_name: Miguel A. full_name: Argüello Cordero, Miguel A. last_name: Argüello Cordero - first_name: Roland full_name: Schoch, Roland id: '48467' last_name: Schoch orcid: 0000-0003-2061-7289 - first_name: Adam full_name: Neuba, Adam last_name: Neuba - first_name: Stefan full_name: Lochbrunner, Stefan last_name: Lochbrunner - first_name: Matthias full_name: Bauer, Matthias id: '47241' last_name: Bauer orcid: 0000-0002-9294-6076 citation: ama: Krishna A, Fritsch L, Steube J, et al.
