On the rule of mixtures for bimetal composites without bonding
In the present study, three types of bimetal composites, Al 6082 sleeve/Al 6082 core, Mg AZ31 sleeve/Mg AZ31 core and Al 6082 sleeve/Mg AZ31 core, were fabricated by drilling and assembling. The rule of mixtures (ROM) for the flow curves and yield strengths during compressive test were addressed. Our results show that…
Nucleophilic Diboration Strategy Targeting Diversified 1‐Boraphenarene Architectures
Abstract 1‐Boraphenalenes, a class of boron‐doped polyaromatic hydrocarbons, were synthesized by nucleophilic diboration reaction of alkynes. Activation of diboron reagents with a highly basic sp 2 ‐carbanion results in very fast successive C−B bond formations to construct the boracycle. This methodology is characteri…
A Block Diagram of Electromagnetoelastic Actuator for Control Systems in Nanoscience and Nanotechnology
The block diagram and the transfer functions of the electromagnetoelastic actuator are received for control systems in nanoscience and nanotechnology. The block diagram of the electromagnetoelastic actuator is reflected the transformation of electrical energy into mechanical energy, in contrast to Cady’s and Mason’s e…
Dermaseptin-Based Antiviral Peptides to Prevent COVID-19 through In Silico Molecular Docking Studies against SARS-CoV-2 Spike Protein
A pandemic coronavirus disease of 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has now been declared a global pandemic by the World Health Organization. The search for new drugs, especially by utilizing antiviral peptides is a very potential area. Through this study, protein-p…
EBSD pattern simulations for an interaction volume containing lattice defects
A quantitative understanding of the effect of the spatial distribution and density of lattice defects on the electron backscatter diffraction patterns requires careful consideration of the electron-matter interaction volume and the traction free boundary condition on the deformation field for near-surface defects. In…
Experimental and DFT Study of Metal-Free Catalyst for Selective Oxidation of Biomass-Derived Molecule (HMF)
Catalytic conversion of biomass or biomass-derived intermediate to value-added chemicals is important for both biomass waste management and production of industrially important chemicals. Oxidation of 5-hydroximethyl furfural (HMF) is considered one of the most important biomass conversion processes, which resulted in…
Sub-pixel electron detection using a convolutional neural network
Modern direct electron detectors (DEDs) provided a giant leap in the use of cryogenic electron microscopy (cryo-EM) to study the structures of macromolecules and complexes thereof. However, the currently available commercial DEDs, all based on the monolithic active pixel sensor, still require relative long exposure ti…
Fabrication of Homogeneous Non-Noble Metal Nanoparticles within Metal–Organic Framework Nanosheets for Catalytic Reduction of 4-Nitrophenol
Compared with noble metal nanoparticles (MNPs), non-noble MNPs possess obvious advantages owing to their abundant reserves on the earth and low cost. Therefore, the synthesis of small and highly active non-noble MNPs is desirable in practice. With the merits of metal–organic framework (MOF) nanosheets, we develop a no…
Harnessing electrospun nanofibers to recapitulate hierarchical fibrous structures of meniscus
The meniscus has complex biomechanical functions endowed by the hierarchical fibrous structure of its extracellular matrix (ECM), which plays a central role in protecting the knee joint. However, it is challenging to recapitulate the ECM structure of the meniscus. Herein, we used electrospinning to prepare various sca…
Frequency Shift of a SH-SAW Biosensor with Glutaraldehyde and 3-Aminopropyltriethoxysilane Functionalized Films for Detection of Epidermal Growth Factor
The frequency shift of a shear-horizontal surface-acoustic-wave (SH-SAW) biosensor in which the concentration of biomolecule is determined by the amount of its adsorption on the sensing film was studied. Simulation results were compared with experimental results to investigate its sensitivity and to develop a model to…
In Situ Growth of Mo2C on Cathodes for Efficient Microbial Electrosynthesis of Acetate from CO2
Abstract Microbial electrosynthesis (MES) is an electrochemical reduction technique where microorganisms attached to electrodes are used as catalysts for CO2 reduction into chemicals. In situ grown molybdenum carbide (Mo2C) without binder-modified electrodes for MES was constructed in different layer numbers. Results…
9,9-Dimethyl Dihydroacridine-Based Organic Photocatalyst for Atom Transfer Radical Polymerization from Modifying “Unstable” Electron Donor
Organic photocatalytic atom transfer radical polymerization (ATRP) has recently become a research highlight. Organic photocatalysts based on phenothiazine, phenoxazine, and phenazine have been reported and exhibited remarkable performance. All of those structures contain two heteroatoms, which makes the oxidative stat…
Indoor distribution transformers oil temperature prediction using new electro‐thermal resistance model and normal cyclic overloading strategy: an experimental case study
In the energy distribution networks, the most important and valuable equipment is oil‐immersed distribution transformers. Besides, due to the key role of these transformers and their multiplicity, their lifetime monitoring is inevitable. The life of a transformer depends on the weakest solid insulation material (i.e.…
Impact of AlInN Back-Barrier Over AlGaN/GaN MOS-HEMT With HfO₂ Dielectric Using Cubic Spline Interpolation Technique
The dc characteristics of AlGaN/gallium nitride (GaN) metal-oxide-semiconductor-high electron mobility transistor (MOS-HEMT) with an AlInN back-barrier layer has been studied here. An analytical model is proposed for evaluating the charge density (σtot), carrier concentration(nS), drain current (ID), and transconducta…
On the origin of degradation in fuel cells and its fast identification by applying unconventional online-monitoring tools
The key advantage of solid oxide fuel cells (SOFC) – high fuel flexibility – still remains the main challenge disturbing their stability, reliability and durability. Specific operating conditions induce and accelerate various degradation mechanisms and reduce the overall fuel cell lifetime. Identifying and predicting…
Preliminary Assays towards Melanoma Cells Using Phototherapy with Gold-Based Nanomaterials
Cancer like melanoma is a complex disease, for which standard therapies have significant adverse side effects that in most cases are ineffective and highly unspecific. Thus, a new paradigm has come with the need of achieving alternative (less invasive) and effective therapies. In this work, biocompatible gold nanopart…
Plasmon‐induced photothermal effect of sub‐10‐nm Cu nanoparticles enables boosted full‐spectrum solar H2 production
Abstract Distinguishing the contributions from localized surface plasmon resonance (LSPR)induced photothermal effect is a significant challenge in the study of solar hydrogen production. Herein, a well‐defined one‐dimensional Cu/TiO2 heterostructure with Cu size of 3–6 nm is designed to address such issue. Cu nanopart…
Aptamers: a novel targeted theranostic platform for pancreatic ductal adenocarcinoma
Pancreatic ductal adenocarcinoma (PDAC) is an extremely challenging disease with a high mortality rate and a short overall survival time. The poor prognosis can be explained by aggressive tumor growth, late diagnosis, and therapy resistance. Consistent efforts have been made focusing on early tumor detection and novel…
Bogoliubov Fermi surfaces in spin- 12 systems: Model Hamiltonians and experimental consequences
Bogoliubov Fermi surfaces (BFSs) are topologically protected regions of zero energy excitations in a superconductor whose dimension equals that of the underlying normal state Fermi surface. Examples of Hamiltonians exhibiting this ``ultranodal'' phase are known to preserve charge-conjugation ($C$) and parity ($P$) but…
