Ion exchange resins were studied on different length scales by magnetic resonance imaging (MRI) with the focus on their interactions with nanoparticles (NP) and molecular clusters.On the length scale of resin beds (bed diameters <20 mm), the behavior of NP and of molecular clusters was shown to depend on the kind of i…
In condensed matter physics, the electronic structure of crystalline solids is traditionally described by the band theory, which treats electrons as waves propagating through a periodic potential. Recent advances in low-dimensional materials have revealed that the underlying electron trajectories, denoted as Γ, can un…
Radiocatalysis provides a new strategy for activating fluoroform waste and converting it into valuable fluorochemicals. However, for reactions involving free radicals—particularly those occurring under irradiation—it is essential to regulate radical activity in order to achieve highly selective transformations. To thi…
ABSTRACT Several large particle physics experiments rely on scintillation light emitted by liquefied noble gases to detect ionizing radiation. This vacuum‐ultraviolet light is commonly converted to visible light by wavelength‐shifting coatings on photon detectors. Materials combining a large Stokes shift, scalable lar…
Variational Quantum Eigensolvers (VQE) require hundreds to thousands of quantum circuit evaluations to converge from random parameter initialization, severely limiting practical application on near-term NISQ hardware. We investigate whether a 13,156-parameter transformer encoder trained on Hamiltonian-to-optimal-param…
A series of heterocyclic derivatives incorporating the pyrano[3,2-c]quinoline-2,5-dione framework were successfully synthesized via nucleophilic substitution reactions of 6-ethyl-4-chloropyrano[3,2-c]quinoline-3-carbaldehyde 2 with several sulfur nucleophiles. Furthermore, aldehyde 2 underwent condensation reactions w…
Abstract Li2ZrCl6 is a cost-effective chloride solid electrolyte for all-solid-state batteries, yet the mechanistic relationship between dopant chemistry and Li+ transport remains insufficiently understood. Building on prior data-driven screening, Zn, Ti, and Ca are examined as representative metal-site substituents u…

Analysis of the level of developing catalytic systems and technologies for copolymerization of CO 2 with traditional monomers and monomers based on bio-sources has been carried out. An overview of data on the global carbon dioxide market as one of the main raw materials component of the studied technologies, as well a…
This study presents a comprehensive mechanical characterisation of a novel, transparent, amorphous thermoplastic hot-melt adhesive (HMA) film, based on a cyclo olefin polymer, engineered for applications in the automotive, electronics and semi-structural bonding sectors. Quasi-static tensile tests reveal typical therm…

A gym bag under the desk revealed more than camping gear—it held the working woodworker's essential toolkit. David Ohnstad unpacks the hand planes, Japanese saws, chisels, and leather rolls that serious makers actually carry to every project.

In conventional quantum mechanics the state of an electron in a crystalline solid is specified by a wavevector k = (k_x, k_y, k_z) that resides in the Brillouin zone. In this work we introduce an additional quantum number, the hidden momentum k_h, that extends the description of electronic states to a higher–dimension…
Under negative DC corona with a silicon needle cathode, the discharge phenomenon differs markedly from that of metal electrodes, producing “streamer-like pulses” that exhibit significant randomness. To elucidate the formation mechanism, a two-dimensional axisymmetric pin–plate discharge model based on plasma chemical…
Abstract In this study, CoCrFeNi high-entropy alloy coatings were prepared on Q235 steel substrates by direct current electrodeposition. An orthogonal experiment was conducted to investigate the effects of chromium chloride concentration, cathodic current density, deposition time, and pH value on the coating propertie…
Abstract To overcome the limited interfacial interaction between collectors and hard-to-float coal, this study established a composite emulsified collector system using methyl isobutyl carbinol (MIBC) as an interfacial regulating component and Tween 80 as an emulsification stabilizer. The effect of MIBC dosage on the…
Abstract Two-photon polymerization (2PP) enables fabrication of hydrogel constructs with submicron, cell-scale resolution, but hydrogel-based bioinks are markedly more sensitive to process variability than conventional photoresists, and this sensitivity is further amplified when living cells are embedded in the resin.…
The electronic properties of crystalline solids have traditionally been described by the occupancy of atomic orbitals and the resulting band structure derived from Bloch wave functions. Recent advances in low‑dimensional systems and strong correlation physics suggest that electrons may form collective, self‑organized…
This mini-review is intended to show how multimodal imaging could be developed from prototypes and proofs of concept by controlling the nanoscale for improved resolution of life science imaging for broad applications such as bioassays, early diagnoses and further applications. It intends to afford the presentation of…
Abstract We have investigated systematically the consequences of photoexcitation of poly(3-hexylthiophene) (P3HT) embedded in a matrix of inert polystyrene (PS) with respect to structure formation and optoelectronic properties. Based on a comparison of observations made simultaneously in illuminated and non-illuminate…
