Protein-based fibers are used by nature as high-performance materials in a wide range of applications, including providing structural support, creating thermal insulation, and generating underwater adhesives. Such fibers are commonly generated through a hierarchical self-assembly process, where the molecular building…
Abstract Practical mid‐infrared (MIR) coherent light beams generated by frequency conversion in nonlinear optical (NLO) crystals are indispensable in time‐resolved infrared vibrational spectroscopy, remote light detection and ranging, and free‐space communications. Herein, a new titanyl germanate Rb4Li2TiOGe4O12 (RLTG…
Abstract The article examines degradation of a SiC‐based fiber composite containing Tyranno ZMI fibers in water vapor at elevated temperatures (800°C and 1100°C). Degradation is characterized through mechanical tests under cyclic and quasi‐static tensile loading in the near‐threshold regime, at stresses at or slightly…
Bone implant materials cause the most common complication of bone infections in orthopedic surgery, resulting in implant failure. Antibiotic treatment of bone infections leads to problems such as bacterial resistance and reduced osteogenic capacity. In this study, dopamine (DA) was self-polymerized on the surface of P…
Plantar skin on the soles of the feet has a distinct morphology and composition that is thought to enhance its tolerance to mechanical loads, although the individual contributions of morphology and composition have never been quantified. Here, we combine multiscale mechanical testing and computational models of load b…
In recent years, natural polymers such as starch have been widely considered as alternatives to plastics derived from petroleum derivatives in the production of packaging films. Currently, modified starches with new functional features are available that can be used in the production of the above mentioned films. The…
In this work, partially biodegradable green composites have been developed with the help of compression molding technique. Jute fibers were selected as a reinforcement and epoxy resin as matrix material. The influence of alkali treatment on various mechanical properties of jute/epoxy composites was investigated, with…
Achieving efficient spatial modulation of phonon transmission is an essential step on the path to phononic circuits using “phonon currents”. With their intrinsic and reconfigurable interfaces, domain walls (DWs), ferroelectrics are alluring candidates to be harnessed as dynamic heat modulators. This paper reports the…
Abstract Chromium triiodide, CrI3, is emerging as a promising magnetic two-dimensional semiconductor where spins are ferromagnetically aligned within a single layer. Potential applications in spintronics arise from an antiferromagnetic ordering between adjacent layers that gives rise to spin filtering and a large magn…
The two-dimensional macro molecule graphene and its derivatives have widely been investigated for their application as nanofiller in carbon fibre-reinforced composites (CFRC). Research has progressed from techniques that simply mix graphene as a mixing constituent within the composite material to more complex examples…
Among the various factors that contribute to the transition from a linear to a circular economy, the identification of superpolymers with outstanding mechanical as well as barrier properties and zero environmental impact has become a mandatory issue. Such new supermaterials render recycling a concrete option for the e…
We investigate the out-of-equilibrium properties of a system of interacting bosons in a ring lattice. We present a Floquet driving that induces clockwise (counterclockwise) circulation of the particles among the odd (even) sites of the ring which can be mapped to a fully connected model of clocks of two counterrotatin…
Essential oil from aerial parts of Artemisia herba-alba from Morocco was hydrodistilled and its chemical composition oil was investigated by capillary GC and GC/MS. The major components were 1,8-cineole (35.6%) and camphor (24.1%). Artemisia herba-alba essential oil AHAO was tested as corrosion inhibitor of stainless…
Biogenic nanoparticles are the smartest weapons to deal with the multidrug resistant ‘superbugs’ because of their broad spectrum antibacterial propensity as well as excellent biocompatibility. The aqueous biogenic silver nanoparticles (Aq-bAgNPs) and ethanolic biogenic silver nanoparticles (Et-bAgNPs) were synthesized…
A practical and scalable protocol for visible-light-accelerated arylation and alkylation of quinoxalin-2(1H)-ones with hydrazines is reported. In this protocol, a hydrazone-based two-dimensional covalent organic frameworks (2D-COF-1) was employed as the heterogeneous photocatalyst (PC). Due to its excellent photocatal…
Electrocheluminescence (ECL) immunoassay amplified by coreaction accelerators has experienced major breakthroughs in ultrasensitive detection of biomarkers. Herein, CeO 2 /SnS 2 heterostructures were synthesized and applied as a novel coreaction accelerator to enhance the ECL efficiency of the luminol–dissolved O 2 sy…
Nanomedicines have been demonstrated as promising strategies for cancer therapy due to the advantages in pharmacokinetics and drug targeting delivery to tumor tissues. However, creation of delivery platforms able to intrinsically and spatially optimize drug cellular uptake during the entire delivering process remain c…
A simple and eco-friendly Fe 2+ /H 2 O 2 oxidation of microcrystalline celluloses (MCCs) to prepare cellulose nanocrystals (CNCs) with high carboxylation content is proposed. The effects of reaction times on the morphology, microstructure, and chemical and thermal properties of isolated carboxylated CNCs were investig…
We train a neural network as the universal exchange-correlation functional of density-functional theory that simultaneously reproduces both the exact exchange-correlation energy and the potential. This functional is extremely nonlocal but retains the computational scaling of traditional local or semilocal approximatio…
Abstract We construct new quasi-three-dimensional fractal acoustic metamaterials based on adoption of the Menger structure, which offers extraordinary parameters such as double-negative properties and a near-zero density. The resulting metamaterials can thus achieve negative refraction, acoustic focusing and sound tun…
