By depositing a graphene layer on the metallic film with subwavelength hole arrays, the tunable extraordinary transmission property based on the metal-dielectrics-graphene (MDG) structure has been investigated in the terahertz (THz) and near-infrared (NIR) regimes. The influences of operation frequency, composed mater…
Bone tissue is dependent on an efficient blood supply to ensure delivery of nutrients and oxygen. One method to acquire a vascular-engineered bone tissue could be the use of an angiogenic gene-activated scaffold. In the current study, porous chitosan/hydroxyapatite (C/HA) scaffolds were fabricated via freeze-drying wi…
The characteristics are investigated in the p-type Mg-doped GaS and GaSe nanosheets by means of first-principles calculations, showing that with increasing Mg doping concentration, the formation energy increases while the transition level decreases. Moreover, Mg impurity can create a shallower acceptor level in the Ga…
In this study, thermochemical conversion of plastic wastes (PET and PVC) together with an agricultural waste (hazelnut shell) was investigated. In order to determine the thermal and kinetic behaviours, pyrolysis experiments were carried out from room temperature to 800 °C, with a heating rate of 10 °C min(-1) in the p…
Ag supported on AgIO₃ (Ag/AgIO₃ particles), a plasmonic photocatalyst, was synthesized through a facile solid-state ion-exchange procedure followed by reduction with hydrazine hydrate. The particles displayed high activity and stability in the photocatalytic conversion of CO₂ to CH₄ and CO using water vapor under visi…
To identify the microscopic mechanism of heavy-fermion Cooper pairing is an unresolved challenge in quantum matter studies; it may also relate closely to finding the pairing mechanism of high-temperature superconductivity. Magnetically mediated Cooper pairing has long been the conjectured basis of heavy-fermion superc…
Energy harvesting techniques are consolidating as effective solutions to power electronic devices with embedded wireless capability. We present an energy harvesting system capable to sustain sensing and wireless communication using thermoelectric generators as energy scavengers and server's CPU as heat source. We targ…
Atomically thin molybdenum disulfide (MoS₂) sheets were synthesized and isolated via solvent-assisted chemical exfoliation. The charge-dependent electrochemical activities of these MoS₂ sheets were studied using positively charged hexamine ruthenium (III) chloride and negatively charged ferricyanide/ferrocyanide redox…
In this study, the Li 2 ZrO 3 based sorbents with different compositions were synthesized by the solid-state reaction method from the mixtures of Li 2 CO 3, K 2 CO 3 and ZrO 2 . CO 2 sorption properties of Li 2 ZrO 3 based sorbents were investigated by analyzing the phases and microstructure changes with the help of t…
A novel nanofabrication technique based on 4-beam interference lithography is presented that enables the preparation of large macroscopic areas (>50 mm2) of perfectly periodic and defect-free two-dimensional plasmonic arrays of nanoparticles as small as 100 nm. The technique is based on a special interferometer, compo…
Lattice-strained CdTe/CdS:Cu quantum dots (QDs) with a widely tunable near-infrared (NIR) fluorescence emission spectrum (700-910 nm) and long lifetime (up to 1 μs) are synthesized. Based on the multiemission and multi-lifetime of the well-defined QDs, NIR-emitting two-dimensional (2D) codes are achieved by embedding…
A new fluorene-based white light-emitting gold(I) complex with aggregate fluorescence change is reported. The novel luminogen emits direct white light in the solid state without involving complex doping/mixing procedures.
The α-helix is a ubiquitous secondary structural element that is almost exclusively observed in proteins when stabilized by tertiary or quaternary interactions. However, beginning with the unexpected observations of α-helix formation in the isolated C-peptide in ribonuclease A, there is growing evidence that a signifi…
In this work, a self-healing strategy for poly(propylene oxide)s bearing coumarine-benzoxazine units (PPO-CouBenz)s based on light induced coumarine dimerization reactions is described. Four different types of poly(propylene oxide) amines with molecular weights ranging from 440 to 5000 Da were reacted with formaldehyd…
Next generation electronic products, such as wearable electronics, flexible displays, and smart mobile phones, will require the use of unprecedented electroactive soft actuators for haptic and stimuli‐responsive devices and space‐saving bio‐mimetic actuation. Here, a bio‐inspired all‐organic soft actuator with a π–π s…
Cu2CdSnS4 and α/β-Cu2ZnSiS4 meet several criteria for promising nonlinear optical materials for use in the infrared (IR) region. Both are air-stable, crystallize in noncentrosymmetric space groups, and possess high thermal stabilities. Cu2CdSnS4 and α/β-Cu2ZnSiS4 display wide ranges of optical transparency, 1.4-25 and…
Hydrogen sulfide (H2S) is an important gaseous signaling agent mediated by many physiological processes and diseases. In order to explore its role in biological signaling, much effort has been focused on developing organic fluorescent probes to image H2S. However, these downconversion H2S probes are impractical for bi…
A series of narrow‐bandgap π‐conjugated oligomers based on diketopyrrolopyrrole chromophoric units coupled with benzodithiophene, indacenodithiophene, thiophene, and isoindigo cores are designed and synthesized for application as donor materials in solution‐processed small‐molecule organic solar cells. The impacts of…
In recent years, tremendous research efforts have been made towards developing graphene (GR)-based nanocomposites for photocatalytic applications. In this work, surface-coarsened TiO2 nanobelts (SC-TNBs) closely enwrapped with monodispersed Ag nanoparticles (NPs) and GR nanosheets (i.e. Ag/GR/SC-TNBs) were fabricated…
Abstract This study explored the testing technologies characterizing the interaction between asphalt and filler. An atomic force microscope (AFM) was used to describe the surface morphology and surface adhesion force of asphalt mastic and analyze their effect factors. Fourier transform infrared spectroscopy (FTIR) was…
