Construction of heterojunction and decoration cocatalyst are two vital strategies to accelerate migration charge carriers. However, the fabrication routs multi-composites usually complex expensive. In this work, Bi2O2CO3/Bi2O3/Bi ternary composite was fabricated via a facile one-step redox reaction. Ethylene glycol selected as solvent during whole reaction process. Moreover, ethylene an excelle...

We refer to human-robot relationships as Lovotics. In this paper a design process for Lovotics is presented. In order to invoke these relationships, technological solutions can only take us so far. Design played an important role in order to engage users to explore the possibilities of bi-directional, human-robot love. We conducted a user-centric study in order to understand these factors and i...

Abstract In the framework of density functional theory, a comprehensive investigation mechanical, dynamical, and electronic properties compounds CaPdX (X= Sb Bi) is performed. The investigated systems are both mechanically dynamically stable. These claimed to be metallic by structure properties, with intriguing crossing points in close proximity Fermi level. With spin orbit coupling (SOC) inclu...

the aim of this article is to extend the study of the lorentz transformation of order (m,n) from m=1 and n>=1 to all m,n>=1, obtaining algebraic structures called a bi-gyrogroup and a bi-gyrovector space. a bi-gyrogroup is a gyrogroup each gyration of which is a pair of a left gyration and a right gyration. a bi-gyrovector space is constructed from a bi-gyrocommutative bi-gyrogroup that admits ...

This paper proposes a method to simplify a computational model from logistic regression for clinical use without computer. The model was built using human interpreted featrues including some BI-RADS standardized features for diagnosing the malignant masses. It was compared with the diagnosis using only assessment categorization from BI-RADS. The research aims at assisting radiologists to diagno...

We present a novel, capped bowtie nanoantenna capable of achieving simultaneous enhancement of electric and magnetic fields in a broad spectrum spanning visible to near-infrared frequencies. By controlling parameters including nanoantenna array spacing, cap thickness, and bowtie gap spacing, we show magnetic enhancements in excess of 3000 times the incident field, which are among the highest va...

We demonstrate an approach allowing isolating effects of surface plasmon polariton mediated resonant transmission in a periodic grating by means of polarization rotation. The grating comprises a square array of cylindrical holes in an optically thick metallic film. Transmittance data for the co- and cross-polarized cases are described accurately with Fano-type and pure Lorentzian-type line shap...

Utilizing surface enhanced Raman spectroscopy (SERS) to in situ monitor a catalytic reaction requires a bi-functional platform which is both catalytically and plasmonically active. In this study, we developed a novel bimetallic nanostructure, featuring Au-Pd alloy horns selectively grown on the end of Au nanorods (AuNR@AuPd), and employed electron tomography and electron energy loss spectroscop...

The global energy shortage requires the substitute of new energy strategy and various type of new materials are investigated for energy conversion purpose, including thermoelectric, ferroelectric, superconductors, etc.[1,2]. Among them fuel cell batteries are of particular interest due to their high capacity, good stability and reliability. The oxygen reduction reaction (ORR) in the fuel cells ...
