The synthesis of a novel self-colored polyurethane (PU) is described using 4-amino-N-propanoic acid-1,8-naphthalimide dye. To synthesize the self- colored PU, the dye was added to the PU prepolymer at the chain extension step. PU and self-colored PU were characterized by using Fourier transform infrared spectroscopy (…
Abstract Styrene‐based thermoset polymers using vinyl ester crosslinkers offer the potential ability to tune material properties via control of network topology, measured primarily by the distribution of poly(styrene) molecular weight between vinyl esters. Clearly, demonstrating a relationship between topology and pro…

Abstract A highly efficient one‐pot synthetic strategy for the preparation of spiropyrans was developed. The method is free of special equipment and operations, and meanwhile, it is energy‐ and time‐saving compared to the reported three‐step procedures. Tolerated with various solvents, bases, aldehydes, and alkyl brom…
Open-cage silsesquioxanes (IC-POSS, incompletely condensed polyhedral oligomeric silsesquioxane) were herein employed for construction of network polymers by utilizing the open moieties as reactive sites. The obtained polymers were soluble in organic solvents despite the high molecular weights. High thermal stability…
Quantum chemistry based simulations were used to examine the excited state of porphyra-334, one of the fundamental mycosporine-like amino acids present in a wide variety of aqueous organisms. Our calculations reveal three characteristic aspects of porphyra-334 related to either its ground or excited state. Specificall…
Abstract We have recently demonstrated an AC magnetic field sensing scheme using a simple continuous-wave optically detected magnetic resonance of nitrogen-vacancy centers in diamond. This scheme is based on electronic spin double-resonance excited by continuous microwave and radiofrequency (RF) fields. Here, we measu…
Abstract Traditionally, electrochromic materials rely on counter redox materials like ferrocene to realize redox processes. In this work, two novel, closely related series of electrochromic materials bearing push‐pull electronic structure were designed and synthesised (N,N,N’,N’‐tetra(pyridin‐4‐yl)‐1,4‐phenylenediamin…
Medium-carbon low alloy wear-resistant cast steel with different Ni contents (0.08 mass%, 0.77 mass%, 1.74 mass%, 2.43 mass%) were heat treated at 1050 °C, followed by water quenching and tempering at 250 °C. The influence of Ni content on the microstructure, hardness, impact toughness and abrasive resistance of the c…
In this study, we have investigated the electrical and anchoring energy of ferroelectric liquid crystal (FLC) with the dispersion of SiO2 nanoparticles (NPs). Due to their higher average spontaneous polarization and helical arrangement of FLC molecules, the molecules strongly interacted to SiO2 NPs which increased the…
We reconstruct the interface between ferroelectric (FE) lanthanum-doped lead zirconate titanate (PLZT) and an iridium oxide (IrOx) top electrode (TE), taking advantage of the interdiffusion of Ir and Pb during postdeposition annealing. The tetragonal perovskite phase with a low c/a axis ratio at the IrOx/PLZT interfac…
Recent years, optically controlled phase-change memory draws intensive attention owing to some advanced applications including integrated all-optical nonvolatile memory, in-memory computing, and neuromorphic computing. The light-induced phase transition is the key for this technology. Traditional understanding on the…
Purpose Abundant oil and gas reservoirs in the deep-water are the valuable non-renewable energy sources. However, sea-water could enhance the corrosion of marine equipment such as submarine pipe trees. Various coatings, for example, polyurethane (PU) coatings are sprayed on the steel surfaces to enhance the anti-corro…
The structural modification of graphene at the atomic level is crucial for electrochemical applications. Doping heteroatoms to modify the structure of graphene has widely been adopted. However, the construction and controllable doping of heteroatom-doped graphene remains a challenge. Herein, a novel semisynthetic meth…
We report that luminescence of Eu 3+ ion incorporated into Ruddlesden–Popper phases allows monitoring phase transition in powders (instead of single crystals), in a time-efficient manner (compared to neutron diffraction), and importantly, with greater sensitivity than previous methods. Crystal structure and dielectric…
Abstract A dual‐signal strategy is proposed based on fluorescent biomass‐based carbon dots (BC‐dots) and chitosan stabilized AuNPs (CS@AuNPs) to determine hyaluronidase (HAase). BC‐dots can induce aggregation of CS@AuNPs nanoparticles with a colour change from red to blue. Positively charged CS@AuNPs interacted with t…
The interfacial diffusion between the electrode and thermoelectric legs is a key factor to determine thermoelectric (TE) module performance. Metal elements M (Sn, Ni, Ag, Cu) are frequently used in lead-free solder SAC serials and barrier layers. M’s effects on thermoelectric properties are investigated in this work,…
Biodegradable magnesium-based implants are the subject of a great deal of research for different orthopedic and vascular applications. The targeted design and properties depend on the specific medical function and location in the body. Development of the biomaterial requires a comprehensive understanding of the biolog…
The trivalent f-element coordination chemistry of a novel aminopolycarboxylate complexant was investigated. The novel reagent is an octadentate complexant that resembles diethylenetriamine- N, N, N ′, N ″, N ″-pentaacetic acid (DTPA), but a single N -acetate pendant arm was substituted with a N -2-pyrazinylmethyl func…
Abstract Face‐centered‐cubic (FCC) silver nanoclusters (NCs) adopting either cubic or half‐cubic growth modes have been recently reported, but the origin of these atomic assembly patterns and how they are achieved, which would inform our understanding of larger FCC silver nanomaterials, are both unknown. In this study…
