In this work, we prepared three novel dicyanomethyl radicals having a triphenylamine skeleton, which show thermochromism in the near-infrared (NIR) region based on the reversible dimerization–dissociation reactions. We demonstrated that the coplanar arrangement of the amino group with respect to the benzene ring beari…
In the discussion and analysis of thermal properties (e.g. heat capacity, thermal conductivity) the Debye approximation is typically used to describe the collective behavior of lattice vibrations (phonons) in solid materials. Because the Debye model has been successful in explaining many properties of materials, parti…
Sustainable coating as a replacement for petroleum-derived materials is highly required for packaging and other applications to reduce the generation of land and ocean pollution. In this study, a novel approach has been introduced to incorporate hydrolyzable silane (−Si–OCH 2 CH 3 ) groups in the downstream corn oil b…
Azo dyes that combine electron-withdrawing thiazole/benzothiazole heterocycles and electron-donating amino groups within the very same covalent skeleton exhibit relaxation times for their thermal isomerization kinetics within milli- and microsecond timescales at room temperature. Notably, the thermal back reaction of…
Abstract Hybrid inorganic/organic thermoelectric materials have recently gained increasing research interest, due to their mechanical flexibility and the wide tunability of their components and properties. In this Communication, a new strategy to fabricate an inorganic/organic superlattice of Bi 2 Se 3 hexylamm‐onium…
Abstract Graphene has a great potential to replace silicon in prospective semiconductor industries due to its outstanding electronic and transport properties; nonetheless, its lack of energy bandgap is a substantial limitation for practical applications. To date, straining graphene to break its lattice symmetry is per…
As a precursor of disinfection byproducts, humic acid (HA) has adverse effects on aquatic environments and human health. Currently, many advanced oxidation processes (AOPs) have been proposed to remove HA from drinking water, one of which is photocatalysis. However, the long reaction time required for degradation and…
Axial coordination in nickel(II) porphyrins has been thoroughly investigated and is well understood. However, isolated five-coordinate nickel(II) porphyrins are still elusive after 50 years of intense research, even though they play a crucial role as intermediates in enzymes and catalysts. Herein we present the first…
Abstract Materials informatics has significantly accelerated the discovery and analysis of materials in the past decade. One of the key contributors to accelerated materials discovery is the use of on-the-fly data analysis with high-throughput experiments, which has given rise to the need for accelerated and accurate…
Abstract In this review, we highlight some relevant examples of C 3 ‐symmetrical molecules that have been reported to form supramolecular polymers and helical aggregates. In particular, the number and type of non‐covalent forces are key to bias the supramolecular polymerization leading from a simple isodesmic or coope…
The morphological evolution of micron-sized calcite crystals dissolved in static acidic solutions, with and without dissolved Pb 2+ ions, was imaged using transmission X-ray microscopy (TXM). The area-normalized dissolution rates measured by TXM increased with time in both Pb-free and Pb-rich solutions but with distin…
Conjugated polymers, especially their second generation with a donor-acceptor alternating structure, have promising properties. These are suitable for two emerging fields, thermoelectrics and bioelectronics, if appropriate structural designs are implemented. This review aims to give a perspective for the potential and…
Abstract Atomically thin transition metal dichalcogenides (TMDs) are ideal candidates for ultrathin optoelectronics that are flexible and semitransparent. Photodetectors based on TMDs show remarkable performance, with responsivity and detectivity higher than 10 3 AW −1 and 10 12 Jones, respectively, but they are plagu…
Although a hydrophobic microtexture at a solid surface most often reflects rain owing to the presence of entrapped air within the texture, it is much more challenging to repel hot water. As it contacts a colder material, hot water generates condensation within the cavities at the solid surface, which eventually builds…
Two novel triphenylamine-based derivatives with dimethylamino substituents, N, N ′-bis(4-dimethylaminophenyl)- N, N ′-bis(4-methoxyphenyl)-1,4-phenylenediamine ( NTPPA ) and N, N ′-bis(4-dimethylaminophenyl)- N, N ′-bis(4-methoxyphenyl)-1,1′-biphenyl-4,4′-diamine ( NTPB ), were readily prepared for investigating the o…
Diels-Alder photocycloaddition of 9-phenylethynylanthracene results in multiple [4 + 2] and [4 + 4] cycloaddition products in solution, which can be controlled to form specific products under a restricted environment. We have exploited the gel phase of a 9-phenylethynylanthracence derivative as a confined medium to sp…
Understanding the deformation behavior of metallic materials containing nanotwins (NTs), which can enhance both strength and ductility, is useful for tailoring microstructures at the micro- and nano- scale to enhance mechanical properties. Here, we construct a clear deformation pattern of NTs in austenitic stainless s…
Abstract Gold (Au) typically crystallizes in a cubic close-packed (ccp) structure to present a face-centered cubic (fcc) lattice or crystal phase. Herein, we demonstrate that Au nanoscale hexagonal stars featuring a hexagonal close-packed (hcp) structure can be synthesized in an aqueous system in the presence of fcc-A…
Abstract Great opportunities emerge not only in the generation of anisotropic plasmonic nanostructures but also in controlling their orientation relative to incident light. Herein, a stepwise seeded growth method is reported for the synthesis of rod‐shaped plasmon nanostructures which are vertically self‐aligned with…
Inducing a robust long-range magnetic order in diamagnetic graphene remains a challenge. While nitrogen-doped graphene is reported to be a promising candidate, the corresponding exchange mechanism remains unclear and is essential to tune further and manipulate magnetism. Within the first-principles calculations, we sy…
