A trade-off between the carrier concentration and carrier mobility is an inherent problem of traditional transparent conducting oxide (TCO) films. In this study, we demonstrate that the electron concentration of TCO films can be increased without deteriorating the carrier mobility by embedding Ag nanoparticles (NPs) i…
Bipolar electrochemistry has recently emerged as a very unique method to address conducting particles in a wireless manner. The technique is often applied to the fabrication of Janus particles; however the chemical nature of the bipolar electrode has been essentially limited to carbon- or metal-based materials. Here,…
The accurate evaluation of ferroelectric thin films operated with interdigitated electrodes is quite a complex task. In this article, we show how to correct the electric field and the capacitance in order to obtain identical polarization and CV loops for all geometrical variants. The simplest model is compared with co…
Summary To improve the large release of smoke and heat for brominated flame retardants (BFRs) in fire hazard, fullerene (C 60 ) had been introduced in high density polyethylene (HDPE)/bromine flame retardant (Deca/Sb 2 O 3 , BFR in short) system in this study. The effects of C 60 on the thermal properties, flame retar…
Near-spherical gold nanoparticles were synthesized using a facile chemical reduction method. The optical properties, size, and morphology of nanofluids were characterized using ultraviolet–visible–near-infrared (UV–Vis–NIR) spectroscopy and transmission electron microscope (TEM). All the gold nanofluids showed better…
The therapeutic potential of liposomes can be amplified when combined with biomaterial scaffolds. Such configurations overcome the convergent demands of therapies by enabling enhanced delivery, environmental responsiveness and potency. Liposomes benefit from the increased physical and mechanical strength, favorable rh…
In multiferroic GaFeO3 (GFO)-type iron oxides, spontaneous polarization and magnetization coexist at room temperature along the [001]GFO and [100]GFO directions, respectively. Due to the large magnetocrystalline anisotropy and polarization direction in GFO, controlling the domain configuration and orientation is cruci…
Recently, transition metal dichalcogenide (TMD) materials have shown promise in electronics and optoelectronics applications. Most of their properties are closely related to their abundant structural phases and phase transitions. For more practical applications in the future, it is necessary to tune the phase transiti…
Many systems benefit from the ability to autonomously signal the occurrence of damage. The development of smart polymer coatings on metals can address scientific challenges such as nondestructive detection of early corrosion to avoid further destruction of materials. Here, pH‐responsive polymer coatings on metals such…
Monolayer (ML) hexagonal (2H) WTe 2 is predicted to be the best channel material of tunnel field effect transistor (TFET) and metal–oxide–semiconductor field effect transistor (MOSFET) among ML transition‐metal dichalcogenides. Actual devices based on 2H WTe 2 typically have a contact with metal. We explore for the fi…
Organic electrochromic (EC) materials are generally known to be electrochemically unstable during the ion intercalation/deintercalation process. One effective method to stabilize them is incorporating graphene derivatives in the polymer matrix, thereby creating strong interaction between graphene derivatives and polym…
This article summarizes the details of an experimental and analytical program that was conducted to study the bond behavior between nickel‐titanium‐niobium shape memory alloy wires and fiber reinforced polymer composites. Understanding this bond behavior will facilitate the design of composite systems that are fabrica…
Photodetectors based on two-dimensional (2D) nanostructures have led to a high optical response, and a long photocarrier lifetime because of spatial confinement effects. Since the discovery of graphene, many different 2D semiconductors have been developed and utilized in the ultrafast and ultrasensitive detection of l…
Two-dimensional black phosphorus is a new material that has gained widespread interest as an active material for optoelectronic applications. It features high carrier mobility that allows for efficient free-carrier absorption of terahertz radiation, even though the photon energy is far below the bandgap energy. Here w…
We report the synthesis of a macrocyclic Gd chelate based on a 1,4,7,10-tetraazacyclododecane-1,4,7-trisacetic acid (DO3A) coordinationn cage bearing an ethoxybenzyl (EOB) moiety and discuss its use as a T 1 hepatobiliary magnetic resonance imaging (MRI) contrast agent. The new macrocyclic liver agent shows high chela…
Pressure driven depolarization behavior has been widely investigated for its scientific significance and practical applications. However, previous related studies were all based on lead-containing ferroelectric (FE) materials leading to detrimental environmental concerns. In the present work, we report the pressure dr…
A series of flame-retardant unsaturated polyester resin (UPR) were prepared by the addition of dimethyl methylphosphonate (DMMP) with various amounts of aluminum hydroxide (ATH) or ammonium polyphosphate (APP) as the flame retardants. The combustion resistance effects of ATH/DMMP and APP/DMMP systems were evaluated by…
The tissue microenvironment has profound effects on tissue-specific regeneration. The 3-dimensional extracellular matrix (ECM) niche influences the linage-specific differentiation of stem cells in tissue. To understand how ECM guides tissue-specific regeneration, we established a series of 3D composite scaffolds conta…
Room-temperature phosphorescence (RTP) from purely organic systems is of practical importance in biological imaging, oxygen sensing and displaying technologies. The key step to obtaining RTP from organic molecules is efficient intersystem crossing (ISC), which is usually low compared to inorganic materials. Here we sh…
Super-resolution lithography holds the promise of achieving three-dimensional (3D) nanopatterning at deep subwavelength resolutions with high throughput. 3D super-resolution lithography schemes demonstrated thus far have all been serial in nature, primarily due to the lack of a photoresist chemistry that not only coup…
