Abstract Heterostructures of two-dimensional transition metal dichalcogenides (TMDs) can offer a plethora of opportunities in condensed matter physics, materials science, and device engineering. However, despite state-of-the-art demonstrations, most current methods lack enough degrees of freedom for the synthesis of h…
The abnormal accumulation of β-amyloid (Aβ) aggregates in the brain is a major pathological hallmark of Alzheimer’s disease. We report a near-infrared (NIR)-active CuBi 2 O 4 -based photocathodic platform that can target intact Aβ aggregates and dissociate them into nontoxic species. Because of its relatively narrow b…
Abstract Different thermoplastic polyurethane (TPU) nanocomposites with various amounts of halloysite nanotube (HNT) were prepared. The morphological, rheological, thermal, mechanical, and electrical properties of the nanocomposites were also investigated. Fourier‐transform infrared spectroscopy shows that increasing…
Abstract External stimuli‐responsive luminogens have attracted a lot of attention in the recent years owing to their potential applications in various fields such as sensing, bio‐probes, and optical devices. In this work, the design and synthesis of a new class of external stimuli‐responsive anthracene based fluoresce…
Abstract Environmental barrier coatings (EBCs) for use with SiC‐based composites in gas turbine engines may fail following reaction with molten silicate deposits. The processes involved may include dissolution of the EBC material into the deposit, reactions that produce new phases, and cracking or spallation upon cool…
This paper reports the nonreciprocal transport in a noncentrosymmetric 2D superconductor, gated MoS2, under out-of-plane magnetic field. The magnitude of the nonreciprocal signal, arising from the vortex rectification by the asymmetric pinning potentials in the trigonal lattice, substantially depends on whether the vo…
There is currently no appropriate therapy for the treatment of injuries that affect the central nervous system. Therefore, scientists have attempted to explore novel methods to improve the neural tissue regeneration, while preventing inhibitory fibro glial scars. In these methods, hollow graphene oxide aerogel was ini…
Abstract Lenses are the most important components of portable and integrable optical systems. Due to the inherent limitation of system sizes, external accessories are required for realizing additional functions such as close‐up or telegraph imaging, making the entire system complicated and cumbersome. Herein, based on…
Abstract Metal oxide semiconductors are promising for solar photochemistry if the issues of excessive charge carrier recombination and material degradation can be resolved, which are both influenced by surface quality and interface chemistry. Coating the semiconductor with an overlayer to passivate surface states is a…
Abstract Doping of carbon dots (CDs) with heteroatoms (e.g., N, S, P, and B) is known as an efficient method to modulate the electronic and optical properties of these fluorescent carbonaceous nanomaterials. Here, we have demonstrated the possibility of in situ azo doping in CDs through hydrothermal treatment of gluco…
The quantum electrostatic heterostructure (QEH) model allows for efficient computation of the dielectric screening properties of layered van der Waals (vdW)-bonded heterostructures in terms of the dielectric functions of the individual two-dimensional (2D) layers. Here, we extend the QEH model by including (1) contrib…
Abstract We use dry CO oxidation to probe CuII dimers in Cu−CHA catalysts in the presence of ammonia. Samples with different Cu/Al and Si/Al ratios were exposed to CO in He at 200 °C after either one of two catalyst pre‐treatments: (i) pre‐oxidization in 8 % O2/He at 550 °C for 1 hour; (ii) pre‐oxidation in 8 % O2/He…
Abstract Layered metal/dielectric hyperbolic metamaterials (HMMs) support a wide landscape of plasmon polariton excitations. In addition to surface plasmon polaritons, coupled Bloch‐like gap‐plasmon polaritons with high modal confinement inside the multilayer are supported. Photons can excite only a subset of these po…
Abstract Research interest in boron nitride nanotubes (BNNTs) has increased after the recent success of large-scale BNNT syntheses using high-temperature-pressure laser ablation or high-temperature plasma methods. Nonetheless, there are limits to the application and commercialization of these materials because of the…
Abstract Excitons in monolayer transition metal dichalcogenides (TMDs) have exceptionally large binding energies and dominate the optical properties of materials. Exploring the relaxation behavior of excitons is crucial for understanding the fundamental physics as well as the performance of TMD-based optoelectronic de…
Design of fiber-reinforced polymer damping laminates has been attracting great interest in industrial sectors for lightweight structural damping applications. The present work investigates the impact of skin, core, neutral, and alternate intertwined basalt/flax fabric on the mechanical and vibrational properties of th…
Depending on the connectivity of solubilizing oligoethylene glycol (OEG) side chains to the π-cores of amphiphilic naphthalene and perylene bisimide dyes, self-assembly in water occurs either upon heating or cooling. Herein, we show that this effect originates from differences in the enwrapping capability of the π-cor…
Hyperbranched polymers represent an intriguing class of shape-persistent soft nanomaterials that could be easily produced in one-pot reaction to obtain highly branched arborescent structures. Although traditional synthesis of hyperbranched polymers suffers from the poorly defined structures and broad molecular weight…
In this work, a facile ionic substitution strategy was initiated to realize the intense red luminescence in Ca 3-δ Ln δ WO 6:Mn 4+ (δ = 0.1, CLnWO:Mn 4+, Ln = La, Gd, Y, Lu,) phosphors evolved from luminescence-ignorable Ca 3 WO 6:Mn 4+ (CWO:Mn 4+ ) material, for the first time. It is fascinating that the emission pro…
We proposed a polarization-insensitive absorber based on strontium titanate (STO) and bulk Dirac semimetal (BDS) in the terahertz (THz) region. The center frequency of the absorption peak can be independently regulated by temperature or Fermi energy level of STO or BDS, respectively. The numerical simulation result re…
