M.ElnagarJ.BansmannC.KranzT.JacobW.MacykR.BeranekarticleIcosahedral Gold Nanoparticles Decorated with Hexon Protein: A Surrogate for Adenovirus Serotype 5The development of synthetic particles that emulate real viruses in size, shape, and chemical composition is vital to the development of imprinted polymer-based sorbent materials (MIPs). In this study, we address surrogates for adenovirus type 5 (Adv 5) via the synthesis and subsequent modification of icosahedral gold nanoparticles (iAuNPs) decorated with the most abundant protein of the Adv 5 (i.e., hexon protein) at the surface. CTAB-capped iAuNPs with dimensions between 40-90 nm were synthesized, and then CTAB was replaced by a variety of polyethylene glycols (PEGs) in order to introduce suitable functionalities serving as anchoring points for the attachment of hexon protein. The latter was achieved by non-covalent linking of the protein to the iAuNP surface using a PEG without reactive termination (i.e., methoxy PEG thiol, mPEG-SH, Mn=800). Alternatively, covalent anchoring points were generated by modifying the iAuNPs with a bifunctional PEG (i.e., thiol PEG amine, SH-PEG-NH2), followed by the addition of glutaraldehyde. X-ray photoelectron spectroscopy (XPS) confirmed the formation of the anchoring points at the iAuNP surface. Next, the amino groups present in the amino acids of hexon protein interacted with the glutaraldehyde. iAuNPs before and after PEGylation were characterized using dynamic light scattering (DLS), XPS, transmission electron microscopy (TEM), scanning electron microscopy (SEM), and UV-vis spectroscopy, confirming the CTAB-PEG exchange. Finally, the distinct red-shift obtained in the UV-vis spectra of the pegylated iAuNPs in the presence of hexon protein, the increase of the hydrodynamic diameter, the change of the zeta potential as well as the selective binding of the hexon-modified iAuNPs towards a hexon-imprinted polymer (HIP), confirmed both the successful covalent and non-covalent attachment at the iAuNP surface.2023110.1007/s00216-022-04368-xAnalytical and Bioanalytical Chemistry415Springer Science and Business Media LLC2080-209111B.Fresco-CalaÁngela I.López-LorenteA.BatistaM.DincJ.BansmannR.

J.BehmarticleSwitchable Polyacrylonitrile-Copolymer for Melt-Processing and Thermal Carbonization - 3D Printing of Carbon Supercapacitor Electrodes with High CapacitancePolyacrylonitrile (PAN) represents the most widely used precursor for carbon fibers and carbon materials. Carbon materials stand out with their high mechanical performance, but they also show excellent electrical conductivity and high surface area. These properties render carbon materials suitable as electrode material for fuel cells, batteries, and supercapacitors. However, PAN has to be processed from solution before being thermally converted to carbon, limiting its final format to fibers, films, and non-wovens. Here, we present a PAN-copolymer with an intrinsic plasticizer to reduce the melting temperature and avoid undesired entering of the thermal carbonization regime. This plasticizer enables melt extrusion-based additive manufacturing (EAM). The plasticizer in the PAN-copolymer can be switched to increase the melting temperature after processing, allowing the 3D-melt-printed workpiece to be thermally carbonized after EAM. Melt-processing of the PAN copolymer extends the freedom-in-design of carbon materials to mold-free rapid prototyping, in the absence of solvents, which enables more economic and sustainable manufacturing processes. As an example for the capability of this material system, we print open meshed carbon electrodes for supercapacitors that are metal- and binder-free with an optimized thickness of 1.5 mm and a capacitance of up to 387 mF cm-2 .

C.KuehnearticleReversible Growth of Gold Nanoparticles in the Low-Temperature Water−Gas Shift ReactionSupported gold nanoparticles are widely studied catalysts and are among the most active known for the low-temperature water−gas shift reaction, which is essential in fuel and energy applications, but their practical application has been limited by their poor thermal stability. The catalysts deactivate on-stream via the growth of small Au nanoparticles. Using operando X-ray absorption and in situ scanning transmission electron microscopy, we report direct evidence that this process can be reversed by carrying out a facile oxidative treatment, which redisperses the gold nanoparticles and restores catalytic activity. The use of in situ methods reveals the complex dynamics of supported gold nanoparticles under reaction conditions and demonstrates that gold catalysts can be easily regenerated, expanding their scope for practical application.2022110.1021/acsnano.2c06504ACS Nano16915197–15205J.

J.BehmM.Wohlfahrt-MehrensP.AxmannarticleEffect of Three-in-One Surface Modification of Spherical, Co-Free Li-Rich Cathode Material for Li-Ion Batteries (Li1.2Mn0.6Ni0.2O2) with Citric AcidThe electrochemical activation of Li2MnO3 domains in Li- and Mn-rich layered oxides (LRLO) is highly important, and can be tuned by surface modification of the active materials to improve their cycling performance. In this study, citric acid was employed as a combined organic acid, reducing agent, and carbon precursor in order to remove surface residues from the calcination process, implement an oxygen deficient layer on the surface of the primary LRLO particles, and cover their surface with a carbon-containing coating after a final annealing step. A broad selection of bulk and surface sensitive characterization methods was used to characterize the post-treated spherical particles, providing the evidence for successful creation of an oxygen deficient near-surface region, covered by carbon-containing deposits. Post-treated materials show enhanced electrochemical discharge capacities after progressive Li2MnO3 activation, reaching maximum capacities of 247 mAh g-1. Gassing measurements reveal the suppression of oxygen release during the first cycle, concomitant with an increased CO2 formation for the carbon-coated materials. The voltage profile analysis in combination with post-mortem characterization after 300 cycles provide insights into the aging of the treated materials, which underlines the importance of the relationship between structural changes during scalable post-treatment and the electrochemical performance of the powders.2022110.1149/1945-7111/acaa5cJournal of The Electrochemical Society16912053312F.KleinC.PfeifferJ.BansmannZ.JusysR.

J.BehmarticleAtmospheric pressure plasma-jet treatment of polyacrylonitrile-nonwovens:~Activation leading to high surface area carbon electrodesCarbon nanofiber nonwovens (CFN) are powerful electrode materials withexceptional performance in energy storage devices, such as batteries andsupercapacitors. Small fiber‐diameters together with hierarchical porosity endowCFN‐electrode materials with large surface areas and high electrical capacitance.Porosity of the fiber surface is often realized by corrosive activation methods suchas wet‐etching or using oxidative gases at elevated temperatures. In this study, wepresent a chemical‐free, environmental‐friendly, and easily controllable surfaceactivation method using an atmospheric pressure plasma‐jet. We investigate thebest instant for activation along the process chain and show that the surface areaof nanofiber nonwovens can be tailored by adjusting the plasma exposure‐dose.Plasma‐activated CFNs showan almost 20‐fold increase incapacitance (CspPJ=10.1F/g)inan electrochemical supercapa-citor setup compared to non-activated CFN (CspnoPJ=0.55F/g).2022110.1002/ppap.202200114Plasma Processes and Polymers19220011412A.HoffmannM.UhlM.CeblinJ.BansmannT.JacobA. J. C.KuehnearticleAtmospheric Pressure Plasma-Jet Treatment of PAN-Nonwovens: Carbonization of Nanofiber ElectrodesCarbon nanofibers are produced from dielectric polymer precursors such as polyacrylonitrile (PAN). Carbonized nanofiber nonwovens show high surface area and good electrical conductivity, rendering these fiber materials interesting for application as electrodes in batteries, fuel cells, and supercapacitors. However, thermal processing is slow and costly, which is why new processing techniques have been explored for carbon fiber tows. Alternatives for the conversion of PAN-precursors into carbon fiber nonwovens are scarce. Here, we utilize an atmospheric pressure plasma jet to conduct carbonization of stabilized PAN nanofiber nonwovens. We explore the influence of various processing parameters on the conductivity and degree of carbonization of the converted nanofiber material. The precursor fibers are converted by plasma-jet treatment to carbon fiber nonwovens within seconds, by which they develop a rough surface making subsequent surface activation processes obsolete. The resulting carbon nanofiber nonwovens are applied as supercapacitor electrodes and examined by cyclic voltammetry and impedance spectroscopy. Nonwovens that are carbonized within 60 s show capacitances of up to 5 F g−1Journal Article2022110.3390/c8030033C8333A.HoffmannM.UhlM.CeblinF.RohrbachJ.BansmannM.MallahH.HeuermannT.JacobA. J. C.KuehnearticleA combined XPS and computational study of the chemical reduction of BMP-TFSI by lithiumEmploying density functional theory (DFT) calculations and x-ray photoelectron spectroscopy (XPS), we identify products of the reaction of the ionic liquid N,N - butylmethylpyrrolidinum bis(triuoromethylsulfonyl)imide (BMP-TFSI) with lithium in order to model the initial chemical processes contributing to the formation of the solid electrolyte interphase in batteries. Besides lithium oxide, sulfide, carbide and fluoride, we find lithium cyanide or cyanamide as possible, thermodynamically stable products in the Li-poor regime, whilst Li$_{\textrm{3}}$N is the stable product in the Li-rich regime. The thermodynamically controlled reaction products as well as larger fragments of TFSI persisting due to kinetic barriers could be identified by a comparison of experimentally and computationally determined core level binding energies.2022110.1002/batt.202200307Batteries & Supercaps12Wiley-VCH
