Abstract Commercial shellfish aquaculture is vulnerable to the impacts of ocean acidification driven by increasing carbon dioxide (CO2) absorption by the ocean as well as to coastal acidification driven by land run off and rising sea level. These drivers of environmental acidification have deleterious effects on biomi…
This paper investigates electromagnetic (EM) vortex imaging based on dual coupled orbital angular momentum (OAM) beams. An OAM-generating scheme is proposed to generate radio waves carrying various dual coupled OAM at the X-frequency band and the experimental results of radar imaging in an anechoic chamber are illustr…
${\mathrm{Sr}}_{2}{\mathrm{RuO}}_{4}$ is one of the most promising candidates of a topological superconductor with broken time-reversal symmetry because a number of experiments have revealed evidence for a spin-triplet chiral $p$-wave superconductivity. To clarify the time-reversal symmetry of ${\mathrm{Sr}}_{2}{\math…
Metal-organic frameworks (MOFs) offer ample characteristics, such as easy synthesis, high surface area, tunable porosities, open metal sites, post-synthesis modification, making them attractive for diverse applications. Since magnetic particles can be positioned and separated by a magnetic field, magnetic framework co…
Economical and highly effective catalysts are crucial to the electrocatalytic hydrogen evolution reaction (HER), and few-layer black phosphorus (phosphorene) is a promising candidate because of the high carrier mobility, large specific surface area, and tunable physicochemical characteristics. However, the HER activit…
base shell through emulsion-templated interfacial polycondensation and then coating a molecularly imprinted polymeric layer with bisphenol A (BPA) as a template molecule through surface free-radical polymerization. The morphology, microstructure, and chemical structure of the resultant molecularly imprinted phase-chan…
Although Sn-Pb perovskites sensing near-ultraviolet-visible-near-infrared light could be an attractive alternative to silicon in photodiodes and imaging, there have been no clear studies on such devices constructed on metal/silicon substrates, hindering their direct integration with complementary metal-oxide semicondu…
Idebenone (IDE) is an antioxidant drug active at the level of the central nervous system (CNS), whose poor water solubility limits its clinical application. An IDE/2-hydroxypropyl-β-cyclodextrin (IDE/HP-β-CD) inclusion complex was investigated by combining experimental methods and theoretical approaches. Furthermore,…
We report a new AB-type benzoxazine monomer, containing both maleimide and furan groups, which exhibits diversified polymerization mechanisms rather than the common single linear polymerization or ring-opening polymerization that leads to cross-linked structures. In addition, the polybenzoxazine obtained directly from…
The alarmone (p)ppGpp regulates diverse targets, yet its target specificity and evolution remain poorly understood. Here, we elucidate the mechanism by which basal (p)ppGpp inhibits the purine salvage enzyme HPRT by sharing a conserved motif with its substrate PRPP. Intriguingly, HPRT regulation by (p)ppGpp varies acr…
The catalytic performance of zirconium-based metal–organic frameworks (UiO-66, UiO-67, and MOF-801) in cyclohexene oxidation with aqueous hydrogen peroxide can be greatly improved by adding a source of protons directly into the reaction mixture. A blend of Zr-MOF and protons favors heterolytic activation of H 2 O 2 an…
Increasing cement production and its substantial contribution to anthropogenic CO 2 emissions (∼5–8%) have led to the pursuit of alternative, sustainable cements. These sustainable cements often contain non-negligible amounts of alkalis (Na or K) which significantly influence the resulting material’s performance. Howe…
Abstract The mechanism of the adsorption and grafting of diazonium cations onto the surface of graphyne and graphdiyne was investigated using Density Functional Theory (DFT). The adsorption energy (both in vacuum and water as solvent) of the phenyl diazonium cation was evaluated at three different positions of the gra…
Abstract In the present study, a comparative compression investigation of anti-tetrachiral and modified re-entrant lattices was conducted in-plane direction using experimental and numerical analyses. Lattice structures were manufactured using fused deposition modelling 3D printing technology and crushed at quasi-stati…
Reaction in well-designed solids allows yielding products with high selectivity and unique compounds that cannot be obtained in solution. However, the precise tuning of the arrangement of reactants in solids for the versatile application of solid-phase reactions remains a challenging subject. Here, a [2 + 2] photocycl…
Although high-resolution single-particle cryo-electron microscopy (cryo-EM) is now producing a rapid stream of breakthroughs in structural biology, it nevertheless remains the case that the preparation of suitable frozen-hydrated samples on electron microscopy grids is often quite challenging. Purified samples that ar…
The increasing threat of explosions on the battle field and the terrorist action requires the development of more effective blast resistance materials and structures. Curved structure can support the external loads effectively by virtue of their spatial curvature. In review of the excellent energy absorption property…
A dual-redox-additive-enhanced Zn–Br 2 “supercapattery” is demonstrated with battery-level energy density and capacitor-level power density.
The generation of photocatalytic hydrogen via water splitting under light irradiation is attracting much attention as an alternative to solve such problems as global warming and to increase interest in clean energy. However, due to the low efficiency and selectivity of photocatalytic hydrogen production under solar en…
Highly oriented niobium pentoxide Nb 2 O 5 nanoflake-like morphology films were deposited at a certain metal of 2.5 mg ml −1 . Different niobium concentrations of 1.5, 2.5, and 3.5 mg ml −1 were used and reacted with water at a temperature of 150 °C for 72 h as a deposition time. The morphology of the deposited films…
