Abstract Diverse reproduction modes of bio‐organisms open new intriguing opportunities for biochemistry‐enabled materials. Herein, a new strategy is developed to explore biodirected structures for functional materials via controlling the reproduction mode. Yeast with sexual or asexual reproduction mode are employed in…
Abstract A highly enantioselective synthesis of 1,12‐disubstituted [4]carbohelicenes is reported. The key step for the developed synthetic route is a Au‐catalyzed intramolecular alkyne hydroarylation, which is achieved with good to excellent regio‐ and enantioselectivity by employing TADDOL‐derived (TADDOL=α,α,α,α‐tet…
In this work, Sr2+ dopant effects of Ba0.9Sr0.1TiO3 and La0.9Sr0.1CrO3-δ doped-perovskite nanoparticles on increasing proton conductivity, fuel cell performance, and mechanical and thermal stability of polybenzimidazole-based nanocomposite membranes were studied. The Sr2+ dopant creates cation vacancies in Ba0.9Sr0.1T…
Abstract Misfit stresses in the γ″-strengthened Ni-base superalloy Inconel 718 were calculated from the measured constrained misfit strain using Eshelby’s inclusion method. The constrained misfit strains of the γ″ precipitates were measured using neutron diffraction at various temperatures with the aid of the stress-i…
A novel surface finishing method named magnetic shear thickening finishing that combines the intelligent shear thickening fluids and magnetic field action is proposed. The magnetic shear thickening finishing media, which is a combination of carbonyl iron particles and SiC particles in a base medium of shear thickening…
The leaching out of toxic elements from metallic bioimplants has serious repercussions, including allergies, peripheral neuritis, cancer, and Alzheimer's disease, leading to revision or replacement surgeries. The development of advanced structural materials with excellent biocompatibility and superior corrosion resist…
Abstract This study reports the photocatalytic efficiencies of CaBiO3 (CBO) towards the degradation of contaminants of emerging concern (CEC), such as ciprofloxacin and tetracycline, under solar light irradiation. CaBiO3 was synthesized using glycine‐complexation (GC) and ion‐exchange (IE) methods. The structural diff…
Porphyrins are fascinating molecules with applications spanning various scientific fields. In this review we present the use of periodic density functional theory (PDFT) calculations to study the structure, electronic properties, and reactivity of porphyrins on ordered two dimensional surfaces and in the formation of…
Abstract Studies on the photoelectronic properties of perovskite solar cells (PSCs) made from non‐PbI2 precursors are seldom reported. In this study, a series of transient techniques are applied to investigate the charge recombination and trap distribution in an efficient PSC fabricated using a low‐toxicity Pb(NO3)2/w…
Abstract Layered sodium metal oxide cathodes have much broader choice of transition metal elements than the Li counterparts. A reversible Cu 2+/3+ redox couple has recently been introduced in such Na cathodes. To study the role of Cu, here P2‐type layered Na 0.75 Mn 0.6 Fe 0.2 (Cu x Ni 0.2‐ x )O 2 compounds have been…
The exfoliation of two-dimensional metal–organic frameworks (2D MOFs) to prepare few-layered MOF nanosheets (MONs) has been of great interest in recent years. In this work, an efficient and environmentally friendly liquid-exfoliation method is developed to produce stable and high-concentration dispersions of few-layer…
Abstract Urea has shown a potential importance as a possible alternative hydrogen‐storage source for low‐temperature fuel cells. Besides, the electrooxidation of urea provides an efficient solution for the disposal of wastewater in the agricultural industry, but the state‐of‐the art urea electrocatalysis suffers from…
The mechanical response of composite structures may be affected by harsh environments, particularly when the matrix has a major contribution, e.g. with off-axis plies. This study aims at investigating the influence of the winding pattern on the axial compressive behavior of filament wound composite cylinder under hygr…
Abstract The chiral feature of γCD‐MOF, and especially the emergent cubic void, was not unveiled so far. Now, through the host–guest interaction between γCD‐MOF and achiral luminophores with different charges and sizes, the unique cubic chirality of the emerging void in γCD‐MOF as well as a size effect on CPL inductio…
A new nitrogen-rich microporous polymer (PAN-FPP5) containing pillar[5]arene macrocycles was fabricated via facile polycondensation between pillar[5]arene-based monomer (FPP5) bearing two aldehyde moieties and melamine. Compared with the macrocycle-free category, PAN-FPP5 exhibited superior CO 2 uptake (12.5 wt % vs 9…
Single-chain Janus nanoparticle of the example polymer polystyrene- block -poly(2-vinylpyridine)- block -polyethylene oxide (PS- b -P2VP- b -PEO) was achieved by intramolecular crosslinking via complexation of P2VP with cobalt octacarbonyl, while the metallic complex was incorporated within the crosslinked core. It is…
The skin is the largest human organ, and defects in the skin with a diameter greater than 4 cm do not heal without treatment. Allogeneic skin transplantation has been used to allow wound healing, but many grafts do not survive after implantation, due to multiple complications in the procedure. In the present study, th…
Biologically inspired structural color hydrogels with magnetic- and photothermal-controlled self-healable abilities were fabricated by integrating magnetic-responsive photonic crystals into gelatin hydrogels. The self-healable ability of the hydrogel systems was derived from the magnetic response and light-absorbing a…
Chaperonin-containing TCP-1 (CCT or TRiC) is a multi-subunit complex that folds many of the proteins essential for cancer development. CCT is expressed in diverse cancers and could be an ideal therapeutic target if not for the fact that the complex is encoded by eight distinct genes, complicating the development of in…
Ferroelectric field-effect transistors (FeFETs) have been considered as promising electrically switchable nonvolatile data storage elements due to their fast switching speed, programmable conductance, and high dynamic range for neuromorphic applications. Meanwhile, FeFETs can be aggressively shrunk to the atomic scale…
