Cavitation bubbles collapsing in the vicinity to a solid substrate induce intense micro-convection at the solid. Here we study the transient near-wall flows generated by single collapsing bubbles by chronoamperometric measurements synchronously coupled with high-speed imaging. The individual bubbles are created at con…
A series of amine oxide and acylamide derivatives of polyethylenimine, both hyperbranched polyethylenimine (HPEI) and linear polyethylenimine (LPEI), has been synthesized. Their performance as crystal growth inhibitors of structure II tetrahydrofuran (THF) hydrate has been investigated. In general, the amine oxide der…
The statistics of selenium chain length distribution in GexSe100-x glasses with 5 ≤ x ≤ 20 are investigated using a combination of high-resolution, two-dimensional (77)Se nuclear magnetic resonance (NMR) spectroscopy and quantum chemical calculations. This combined approach allows for the distinction of various seleni…
Abstract The present work has the objective of fabricating graphene oxide (GO) and amine‐functionalized graphene oxide (F‐GO) reinforced epoxy composites using the casting method. Epoxy resin was dispersed separately with GO (0.5 wt%) and F‐GO (0.5 and 1 wt%), and then the epoxy resin mixture cured with triethylenetet…
Two-dimensional (2D) dielectric photonic crystals with accidentally induced Dirac-like points (DLPs) at the Brillouin zone center behave as an effective zero-index medium under certain conditions. We investigated different 2D square lattice dielectric PCs, such as dielectric rods of square and circular cross sections…
Abstract There are many application areas, where the ability to accurately predict the speed of expansion of fragments from explosively disseminated porous shells is important. For inert materials this speed in part determines the size of the resulting cloud. For reactive materials this speed in part determines the ab…
Photoluminescent materials, that are now ubiquitous in our everyday life, have particularly attracted the attention of the scientific community these past few years due to potential important applications such as in bioimaging, sensing, or optoelectronics. In this context, relatively few different families of molecule…
Cold plasma generated by dielectric barrier discharge (DBD) at atmospheric pressure was adopted for preparation of commercial TiO 2 Degussa P25 supported Au catalysts (Au/P25-P) with the assistance of the deposition-precipitation procedure. The influences of the plasma reduction time and calcination on the performance…
We studied the structural development of symmetric poly(styrene- b -2-vinylpyridine) (PS- b -P2VP) block copolymers during spin-coating using in situ grazing incidence small-angle X-ray scattering (GISAXS) measurements. During the spin-coating process, after the formation of the micelles in dilute solution, the select…
In this study, we report an innovative approach aiming to assess the binding affinity between drug molecules and human serum albumin by combining nanoporous anodic alumina rugate filters (NAA-RFs) modified with human serum albumin (HSA) and reflectometric interference spectroscopy (RIfS). NAA-RFs are photonic crystal…
Species cooccurrence patterns give significant insights into the processes shaping communities. While biotic interactions have been widely studied using cooccurrence analyses in animals and larger plants, studies about cooccurrences among micro-organisms are still relatively rare. We examined stream diatom cooccurrenc…
Hydrogen release during severe accidents poses a serious threat to containment integrity. Mitigating procedures are necessary to prevent global or local explosions, especially in large steel shell containments. The management of hydrogen safety and prevention of over-pressurization could be implemented through a hydro…
Magnetic colloids in external time-dependent fields are subject to complex induced many-body interactions governing their self-assembly into a variety of equilibrium and out-of-equilibrium structures such as chains, networks, suspended membranes, and colloidal foams. Here, we report experiments, simulations, and theor…
The electrochemical corrosion properties of 26Mn-3Si-3Al and 27Mn-4Si-2Al austenitic steels in two different states were studied in 0.1 M H 2 SO 4 and 3.5% NaCl using potentiodynamic polarization tests. The effect of cold deformation on the microstructure and corrosion behavior of steels was analyzed. In acid solution…
Separation of low viscous oil from water has attracted immense attention in recent times due to the ever‐increasing amount of oily industrial wastewater discharge and frequent oil spill accidents. Hence, there is a persistent demand for the fabrication of robust oil–water separation membranes. Herein, robust oil–water…
We performed a systematic investigation on silicon-doped boron clusters BnSi (n = 8-14) in both neutral and anionic states using quantum chemical methods. Thermochemical properties of the lowest-lying isomers of BnSi(0/-) clusters such as total atomization energies, heats of formation at 0 and 298 K, average binding e…
Copper/single-walled carbon nanotube (SWCNT) composite films were fabricated by electroless deposition. The SWCNTs were formed using the water-assisted chemical vapor deposition method. To prepare copper/SWCNT composite plating baths with homogeneously dispersed SWCNTs, magnetic stirring, ultrasonic homogenization, an…
Graphene quantum dots (GQDs) are promising candidates for potential applications such as novel optoelectronic devices and bio-imaging. However, insufficient light absorption to exhibit their intriguing characteristics. The strong confinement of light caused by the Au nanoparticles as an antenna can considerably boost…
Abstract Pseudo‐single atom Pt catalysts have achieved an excellent selectivity to branched paraffins and cycloalkanes in n‐hexane reforming here. Highly dispersed platinum in single‐atom and small clusters made up of several separated atoms was produced under the inducement of Sn or Zr as promoting components. The Sn…
A substrate-integrated nickel–iron ultrabattery is realized using nickel oxide (NiO) nanoflakes and hematite (α-Fe 2 O 3 ) nanorods as electroactive materials for its positive and negative electrodes, respectively. Direct growth of electroactive materials on a highly conductive stainless steel substrate enhances the m…
