Patterns of species richness are commonly linked to life history strategies. In diatoms, an exceptionally diverse lineage of photosynthetic heterokonts important for global photosynthesis and burial of atmospheric carbon, lineages with different locomotory and reproductive traits differ dramatically in species richnes…
Organic crystals are generally brittle and tend to crack under applied stress. Doped organic crystals are even more brittle because of lattice defects. Herein, the first doped organic crystals 1d@2d, which display elastic bending ability under applied stress, are reported. Moreover, the potential applications of elast…
heterostructure-based memory devices open up an exciting field for optoelectronic infrared memory and programmable logic devices.
Abstract There have been extensive efforts to synthesize crystalline covalent triazine‐based frameworks (CTFs) for practical applications and to realize their potential. The phosphorus pentoxide (P 2 O 5 )‐catalyzed direct condensation of aromatic amide instead of aromatic nitrile to form triazine rings. P 2 O 5 ‐cata…
Abstract Structural design on the atomic level can provide novel chemistries of hybrid MAX phases and their MXenes. Herein, density functional theory is used to predict phase stability of quaternary i ‐MAX phases with in‐plane chemical order and a general chemistry (W 2/3 M 2 1/3 ) 2 AC, where M 2 = Sc, Y (W), and A =…
Realizing the growing number of possible or hypothesized metastable crystalline materials is extremely challenging. There is no rigorous metric to identify which compounds can or cannot be synthesized. We present a thermodynamic upper limit on the energy scale, above which the laboratory synthesis of a polymorph is hi…
The present review covers developments in studies of nanomaterials (NMs) in the environment since our much cited review in 2008. We discuss novel insights into fate and behavior, metrology, transformations, bioavailability, toxicity mechanisms, and environmental impacts, with a focus on terrestrial and aquatic systems…
Abstract Exploring cheap and efficient cocatalysts for enhancing the performance of photocatalysts is a challenge in the energy conversion field. Herein, 2D ultrathin Ti 3 C 2 nanosheets, a kind of MXenes, are prepared by etching Ti 3 AlC 2 with subsequent ultrasonic exfoliation. A novel 2D/2D heterojunction of ultrat…
The use of machine learning methods for accelerating the design of crystalline materials usually requires manually constructed feature vectors or complex transformation of atom coordinates to input the crystal structure, which either constrains the model to certain crystal types or makes it difficult to provide chemic…
In this work, two composite polymer blends, PMMA/SR and PMMA/PUR, reinforced with carbon fibers (CF) were prepared as a suitable material for lower limb prosthetic foot. The tensile properties were measured experimentally. The theoretical part of this work deals with calculations of the deformation and dorsiflexion an…
We demonstrate and measure a hybrid double-band tunable metamaterial absorber in the terahertz region. The measured metamaterial absorber contains of a hybrid dielectric layer structure: a SU-8 layer and a VO 2 layer. Near perfect double-band absorption performances are achieved by optimizing the SU-8 layer thickness…
Preparation of superhydrophobic glass fiber and interfacially reinforced glass fiber/epoxy composites by grafting polysiloxane nanowires, Lv, Junwei, Wang, Bin, Ma, Qi, Li, Mengyao, Wang, Wenjing, Lu, Gaotaihang, Li, Hui, Zhao, Chunxia
Metal oxides have attracted growing interest due to their large scale properties and application in various fields. These oxides have exhibited remarkable electrochemical properties. They are not only cheap, friendly to use, easy to synthesize but also are presenting better energy storage efficiency in response to the…
Mobility is an important parameter to gauge the performance of graphene devices, which is usually measured by FET or Hall methods relying on the use of insulating substrates. However, these methods are not applicable for the case of graphene on semiconductors, because some current will inevitably cross their junctions…
Biaxial compressive experiments for 3D needled C/C–SiC composites parallel to the nonwoven cloth were conducted. The failure mechanisms and mechanical properties of the composites were greatly related to the biaxial compressive stress confinement ratio, R. It was found that out-of-plane shear failure controlled the fa…
The manufacturing of semiconducting films using solution-based approaches is considered a low cost alternative to vacuum-based thin film deposition strategies. An additional advantage of solution processing methods is the possibility to control the layer nano/microstructure. Here, we detail the production of mesoporou…
Effect of sonication time on the synthesis of the CdS nanoparticles within the matrix obtained through the covalent functionalization of multiwall carbon nanotube (MWCNT) with maleic anhydride (MA) – 1-octene copolymer was investigated. Cadmium chloride and thiourea were used as the raw materials. MWCNTs used for the…
Non‑small‑cell lung cancer (NSCLC) is one of the most common malignancies that is responsible for a high level of cancer‑associated mortalities worldwide. Previous evidence has shown that Calotropin is an upstream activator of protein kinase B, which can further inhibit the growth and promote the apoptosis of NSCLC ce…
Dispersion forces play a major role in graphene, largely influencing adhesion of adsorbate moieties and stabilization of functional multilayered structures. However, the reliable prediction of dispersion interactions on graphene up to the relevant ∼10 nm scale is an extremely challenging task: in fact, electromagnetic…
Herein, we demonstrate a facile method for the preparation of microporous organic nanotubes (MONTs) based on a combination of hyper-cross-linking mediated self-assembling strategy and Scholl reaction by using polylactide- b -polystyrene diblock copolymers (PLA- b -PS) as precursors, in which the PS block forms the mic…
