The growth of large-area bilayer graphene has been of technological importance for graphene electronics. The successful application of graphene bilayers critically relies on the precise control of the stacking orientation, which determines both electronic and vibrational properties of the bilayer system. Toward this g…
Zweidimensionales Biodynamit: Chemisch abgetragenes MoS2 (ceMoS2), ein in Wasser dispergierbares, blattförmiges Material, ist ein effizienter photothermischer Nah-Infrarot(NIR)-Energieumwandler. Die ausgezeichneten bio-supramolekularen Eigenschaften von ceMoS2 und die Fähigkeit dieses Materials, biomolekulare Zielstru…
We investigate the two-dimensional highly spin-polarized electron accumulation layers commonly appearing near the surface of n-type polar semiconductors BiTeX (X=I, Br, and Cl) by angular-resolved photoemission spectroscopy. Because of the polarity and the strong spin-orbit interaction built in the bulk atomic configu…
Purpose: To evaluate a green process for the extracellular production of silver (Ag) nanoparticles synthesized and stabilized using Penicillium citrinum isolated from soil.Methods: The pure colonies of Penicillium citrinum were cultured in Czapek dox broth. The supernatant of the broth was examined for the ability to…
This study uses a "bottom-up" approach chemical method to coat nanocrystalline Ni(OH)2 onto multiwalled carbon nanotubes (MWCNTs) for flexible supercapacitor electrodes, where the higher electronic conductivity of MWCNTs permits their use as the supporting backbone onto which Ni(OH)2 can be deposited. The paper portra…
Liposomes are delivery systems that have been used to formulate a vast variety of therapeutic and imaging agents for the past several decades. They have significant advantages over their free forms in terms of pharmacokinetics, sensitivity for cancer diagnosis and therapeutic efficacy. The multifactorial nature of can…
In this work, we present a modification of a stainless steel surface to impart superhydrophobic properties to it that are robust with respect to mechanical stresses associated with cyclic icing/deicing treatment, as well as to long-term contact with aqueous media and high humidity. The durability of the superhydrophob…
Freestanding nanowires have ultrahigh elastic strain limits (4 to 7%) and yield strengths, but exploiting their intrinsic mechanical properties in bulk composites has proven to be difficult. We exploited the intrinsic mechanical properties of nanowires in a phase-transforming matrix based on the concept of elastic and…
Over the last few decades, nanocarriers for drug delivery have emerged as powerful tools with unquestionable potential to improve the therapeutic efficacy of anticancer drugs. Many colloidal drug delivery systems are underdevelopment to ameliorate the site specificity of drug action and reduce the systemic side effect…
The $p$-type semiconductor copper oxide has three distinct phases Cu${}_{2}$O, CuO, and Cu${}_{4}$O${}_{3}$ with different morphologies and oxidation states of the copper ions. We investigate the structural stability and electronic band structure of all three copper oxide compounds using ab initio methods within the f…
Two-dimensional bio-dynamite: Chemically exfoliated MoS2 (ceMoS2), a water-dispersible sheet-like material, is an efficient near-infrared (NIR) photothermal transducer. The superior bio-supramolecular properties of ceMoS2 and the ability of this material to destroy biomolecular targets through near-infrared (NIR) phot…
Graphene's success has shown that it is possible to create stable, single and few-atom-thick layers of van der Waals materials, and also that these materials can exhibit fascinating and technologically useful properties. Here we review the state-of-the-art of 2D materials beyond graphene. Initially, we will outline th…
The photoinduced mechanism of formation of mono- and diadducts between 8-MOP and thymine bases is studied using the ONIOM(MPWB1K/6-31 + G(d,p):B3LYP/6-31G(d,p):UFF) and B3LYP/6-31 + G(d,p) methods. The relevant cycloaddition displays favorable energy barriers and reaction energies in the triplet excited state, which i…
Photopolymerization of high internal phase emulsions based on 2-ethylhexyl (meth)acrylates and ethylene glycol dimethacrylate was carried out in presence of low concentration of different photoinitiators. The stable emulsions obtained by mixing with individual photoinitiators were subjected to low-intensity photopolym…
Von „nano“ zu „super“: Peptidkonjugate aus Cobalt-bindenden und mit Biphenyl-Einheiten terminierten Peptiden wurden für die gerichtete Synthese und Organisation hohler sphärischer Superstrukturen aus CoPt-Nanopartikeln genutzt (siehe Bild). Die magnetisch trennbaren Superstrukturen zeigen elektrokatalytische Aktivität…
In this study, we discussed an efficient approach for the synthesis of camphorquinone from camphor by the continuous reaction of bromination and oxidation. The oxidation of 3-bromocamphor was catalyzed by Fe-porphyrins with air. The catalytic activity of iron-metallated functional porphyrins was investigated under opt…
Mn doping in ZnS nanoplatelets has been shown to induce a structural transition from the wurtzite to the zinc blende phase. We trace the origin of this transition to quantum confinement effects, which shift the valence band maximum of the wurtzite and zinc blende polymorphs of ZnS at different rates as a function of t…
molecular dynamics method, namely elongation molecular dynamics (ELG-MD) is proposed for highly efficient simulations of aperiodic polymer systems. ELG-MD combines the elongation method (ELG) with the Gear predictor corrector (GPC) algorithm of molecular dynamics simulation. In this method, the local gradients acting…
The theoretical crystal-morphology of zinc tricarbohydrazide perchlorate (ZnCP) was studied using the morphology simulation software. The growth trends and surface characteristics were calculated using the Bravais-Friedel-Donnay-Harker (BFDH), Growth Morphology, and Equilibrium Morphology methods; these provide theore…
By using a combination of synchrotron photoemission and a finite element model, the layer‐by‐layer stoichiometry of pulsed laser deposited La 0.7 Sr 0.3 MnO 3 (LSMO) thin films is extracted. For 3‐ and 5‐unit‐cell films, the LSMO stoichiometry at the LSMO/SrTiO 3 interface has been studied, and it is found that the Sr…
