Manipulation of nanomaterials such as nanoparticles (NPs) and nanorods (NRs) to make clusters is of significant interest in material science and nanotechnology due to the unusual collective opto-electric properties in such structures that cannot be found in the individual NPs. This work demonstrates an effective way t…
High Resolution Image Download MS PowerPoint Slide Structure–property relationships are a key materials science concept that enables the design of new materials. In the case of materials for application in radiation environments, correlating radiation tolerance with fundamental structural features of a material enable…
By applying hydrostatic pressure, effective tuning on the crystal structure, bandgap, ferroelectric, electric and optoelectronic properties of the multiferroic KBiFe2O5 is demonstrated. A reversible structural transition is identified around 10.3 GPa by in situ synchrotron X-ray diffraction, Raman spectroscopy, and fi…
In recent years, photoluminescent gold nanoclusters have attracted considerable interest in both fundamental biomedical research and practical applications. Due to their ultrasmall size, unique molecule-like optical properties, and facile synthesis gold nanoclusters have been considered very promising photoluminescent…
Thermogravimetric analysis and differential scanning calorimetry were used to study the thermal degradation and thermal stability of bamboo powder and its composites (EP-BFC) in a nitrogen atmosphere. The thermal stability of EP-BFC decreased as the bamboo filler-loading increased. Compared with epoxy, bamboo powder h…
We present the synthesis, structure, magnetic properties, as well as the Mössbauer and electron paramagnetic resonance studies of a ring-shaped [Fe III 4 Ln III 2 (Htea) 4 (μ-N 3 ) 4 (N 3 ) 3 (piv) 3 ] (Ln = Y 1, Gd 2, Tb 3, Dy 4, Ho 5, Er, 6 ) coordination cluster. The Dy, Tb, and Ho analogues show blocking of the ma…
Radiotherapy is a critical strategy and standard adjuvant approach to glioblastoma treatment. One of the major challenges facing radiotherapy is to minimize radiation damage to normal tissue without compromising therapeutic effects on cancer cells. Various agents and numerous approaches have been developed to improve…
9,10-Bis(phenylethynyl)anthracenes (BPEAs) are an important class of dyes in various applications including chemiluminescence emitters, materials for photon upconversion, and for optoelectronic devices. Some of these applications require control over the packing modes of the molecules within the active layer, which ca…
The aim of this study was to screen the antibacterial activity of biogenic platinium nanoparticles. During this study platinum nanoparticles prepared from marine actinobacteria (Streptomyces sp.) were used to access antibacterial activity against Escherichia coli, Enterobacter cloacae, Klebsiella pneumoniae, Proteus v…
Bio-synthesis approach for gold nanoparticles (AuNPs) has received tremendous attention as an efficient and eco-friendly process. However, kinetic growth and colloidal stability of AuNPs synthesized by this process remained challenging. In this study, Elaeis guineensis (oil palm) kernel (OPK) extract prepared in an io…
Abstract Nitrogen-doped graphene oxides (GO:N x ) were synthesized by a partial reduction of graphene oxide (GO) using urea [CO(NH 2 ) 2 ]. Their electronic/bonding structures were investigated using X-ray absorption near-edge structure (XANES), valence-band photoemission spectroscopy (VB-PES), X-ray emission spectros…
ABSTRACT In this work, a series of flexible polyimide composite foams with dianhydride and isocyanate as the starting materials were prepared by pre‐dispersing vermiculite in isocyanate. The experimental results revealed that the cellular diameter of foams obviously decreased with the addition of vermiculite. The open…
This paper presents the results of the synthesis and evaluation of thick thermoelectric films that may be used for such applications as thermoelectric power generators. Two types of electrochemical deposition methods, constant and pulsed deposition with improved techniques for both N-type bismuth telluride (Bi2Te3) an…
A novel aptasensor platform has been developed for quantitative detection of adenosine triphosphate (ATP) based on a ratiometric surface-enhanced Raman scattering (SERS) strategy. The thiolated 3'-Rox-labeled complementary DNA (cDNA) is first immobilized on the gold nanoparticle (AuNP) surface and then hybridizes with…
Surface diffusion of molecular glasses is found to be orders of magnitude faster than bulk diffusion, with a stronger dependence on the molecular size and intermolecular interactions. In this study, we investigate the effect of variations in bulk dynamics on the surface diffusion of molecular glasses. Using the tobacc…
With the emerging applications of copper(I) thiocyanate (CuSCN) as a transparent and solution‐processable hole‐transporting semiconductor in numerous opto/electronic devices, fundamental studies that cast light on the charge transport physics are essential as they provide insights critical for further materials and de…
Abstract Natural materials such as bone and insect cuticle are capable of self‐repair, a facility that greatly increases their durability and safe working stress. Some engineering materials have also been designed to be self‐healing, although currently they cannot match the performance of natural materials as regards…
Predicting structures at the atomic scale is of great importance for understanding the properties of materials. Such predictions are infeasible without efficient global optimization techniques. Many current techniques produce a large amount of idle intermediate data before converging to the global minimum. If this inf…
Silver nanogrid based flexible transparent electrode is recognized as the most promising alternative to ITO electrode for organic electronics, owing to its low production cost and excellent flexibility. Typically, a highly conductive thin film coating layer, such as highly conductive PEDOT:PSS (HC-PEDOT:PSS) is usuall…
We report the first measurements of spin injection into graphene through a 20-nm-thick tungsten disulphide (${\mathrm{WS}}_{\text{2}}$) layer, along with a modified spin relaxation time (${\ensuremath{\tau}}_{\text{s}}$) in graphene in the ${\mathrm{WS}}_{\text{2}}$ environment, via spin-valve and Hanle spin-precessio…
