    ABSTRACT: The development of polymeric luminescent nanomaterials for biomedical applications has recently attracted a large amount of attention due to the remarkable advantages of these materials compared with small organic dyes and fluorescent inorganic nanomaterials. Among these polymeric luminescent nanomaterials, polymeric luminescent nanomaterials based on dyes with aggregation-induced emission (AIE) properties should be of great research interest due to their unique AIE properties, the designability of polymers and their multifunctional potential. In this review, the recent advances in the design and biomedical applications of polymeric luminescent nanomaterials based on AIE dyes is summarized. Various design strategies for incorporation of these AIE dyes into polymeric systems are included. The potential biomedical applications such as biological imaging, and use in biological sensors and theranostic systems of these polymeric AIE-based nanomaterials have also been highlighted. We trust this review will attract significant interest from scientists from different research fields in chemistry, materials, biology and interdisciplinary areas.

    ABSTRACT: Laws of corresponding states known so far demonstrate that certain macroscopic systems can be described in a universal manner in terms of reduced quantities, which eliminate specific substance properties. To quantitatively describe real systems, all these laws of corresponding states contain numerical factors adjusted empirically. Here, we report a law of corresponding states deduced analytically for charge transport via tunneling in molecular junctions, which we validate against current-voltage measurements for conducting probe atomic force microscope junctions based on benchmark molecular series (oligophenylenedithiols and alkanedithiols) and electrodes (silver, gold, and platinum), as well as against transport data for scanning tunneling microscope junctions. Two salient features distinguish the present law of corresponding states from all those known previously. First, it is expressed by a universal curve free of empirical parameters. Second, it demonstrates that a universal behavior is not necessarily affected by strong stochastic fluctuations often observed in molecular electronics. An important and encouraging message of this finding is that transport behavior across different molecular platforms can be similar and extraordinarily reproducible.

    ABSTRACT: La-doped p-type ZnO nanofibers were successfully synthesized by electrospinning, followed by calcination. The microstructure and morphology of the La-doped ZnO nanofibers were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy. The field effect curve of individual nanofibers confirms that the resulting La-doped ZnO fibers are p-type semiconductors. The doping mechanism is discussed. Furthermore, crossed p-n homojunction nanofibers were also prepared based on electrospun La-doped p-type ZnO and n-type pure ZnO fibers. The current-voltage curve shows the typical rectifying characteristic of a p-n homojunction device. The turn-on voltage appears at about 2.5 V under the forward bias and the reverse current is impassable.

    ABSTRACT: Graphene quantum dots (GQDs) are a promising category of materials with remarkable size dependent properties like tunable bandgap and photoluminescence along with the possibility of effective chemical functionalization. Doping of GQDs with hetero atoms is an interesting way of regulating their properties. Herein, we report a facile and scalable one-step synthesis of luminescent GQDs, substitutionally co-doped with N, F and S, of average size ~ 2 nm by a microwave treatment of multi-walled carbon nanotubes in a customized ionic liquid medium. This use of ionic liquid coupled with the use of a microwave technique enables not only an ultrafast process for the synthesis of co-doped GQDs, but also provides excellent photoluminescence quantum yield (70 %), perhaps due to the interaction of defect clusters and dopants.

    ABSTRACT: We demonstrate the fabrication of a core-satellites structured BiOBr-CdS photocatalyst with high efficient photocatalytic reactivity via a facile in situ crystallization approach at room temperature. The transmission electron microscopy (TEM) and high-resolution transmission electron microscopy (HR-TEM) results reveal that the BiOBr flakes are surrounded by the CdS particles. The coverage of the satellites on the surface of the BiOBr nanosheets could be controlled by changing the content of CdS, which contributes to the enhanced level of photocatalytic performance. The UV−vis diffuse reflection spectra demonstrates that the visible light absorption of the BiOBr-CdS photocatalyst is also enhanced by CdS loaded. The excellent structural and spectral properties endow the BiOBr-CdS heterojunctions with improved photocatalytic performance pertaining to bisphenol A (BPA) degradation and photocurrent generation. Under visible light irradiation, the optimum photocatalytic activity of BiOBr-CdS at a molar ratio of 1:5 (CdS/BiOBr) is almost 2.8 times and 24.6 times as high as that of pure BiOBr and CdS. The remarkably enhanced photoreactivity should be attributed to the match in the energy levels and close core-satellites structural coupling between the CdS and BiOBr, which greatly facilitates the separation and transfer of photoinduced electron–hole pairs, as confirmed by photoluminescence (PL) and electrochemical impedance spectra (EIS). The present work shed new light on the construction of highly efficient core-satellites heterojunctional photocatalyst for practical applications.

    ABSTRACT: Photonic crystal waveguides and circuits are one of basic modules of the integrated photonic devices. They mainly rely on photonic bandgap to achieve light confinement and manipulation. Here we propose a novel general principle or method to achieve reconfigurable and tunable flat graphene photonic crystal (FG-PC), by selectively electrostatic gating a layer of graphene with periodic gold electrodes. A tunable flat photonic bandgap structure of the FG-PC as a function of the Fermi level is investigated. Reconfigurable FG-PC defect waveguides and cavities created by external patterned-gate-voltage control are also proposed and discussed. The features of reconfigurable /tunable FG-PC will add more flexibility and capabilities for the Single Chip Integration of graphene-based integrated photonic devices.

    ABSTRACT: A simple process for preparing 3D structured graphene (3D-G) by a solution combustion method is reported. The product was deposited with platinum and used for methanol electrooxidation. The catalyst shows considerable enhancement on both activity and stability towards methanol electrooxidation reaction. Characterizations reveal that the Pt/3D-G catalyst has a more negative onset potential as well as a higher electrochemically active specific surface area compared with a commercial Pt/C catalyst. Moreover, the catalyst exhibits higher tolerance to corrosion than carbon black. This work provides an efficient way for preparing 3D-G as a promising support for the oxidation of small organic molecules in fuel cells.

    ABSTRACT: There is a strong demand to replace expensive Pt catalysts with cheap metal sulfides or phosphides for hydrogen generation in water electrolysis. The earth-abundant Fe can be electroplated on carbon cloth (CC) to form high surface area rague-like FeOOH assembly. Subsequent gas phase phosphidation converts the FeOOH to FeP or FeP2 and the morphology of the crystal assembly is controlled by the phosphidation temperature. The FeP prepared at 250 oC presents lower crystallinity and those prepared at higher temperatures 400 oC and 500 oC possess higher crystallinity but lower surface area. The phosphidation at 300 oC produces nanocrystalline FeP and preserves the high-surface area morphology; thus it exhibits the highest HER efficiency in 0.5 M H2SO4; i.e. the required overpotential to reach 10 and 20 mA/cm2 is 34 and 43 mV respectively. These values are lowest among the reported non-precious metal phosphides on CC. The Tafel slope for the FeP prepared at 300 oC is around 29.2 mV/dec comparable to that of Pt/CC, indicating that the hydrogen evolution for our best FeP is limited by Tafel reaction (same as Pt). Importantly, the FeP/CC catalyst exhibits much better stability in a wide range working current density (up to 1 V/cm2), suggesting that it is a promising replacement of Pt for HER.

    ABSTRACT: A new type of biohybrid photo-electrochemical cell was fabricated by the layer-by-layer assembly of photosystem II and reduced graphene oxide. We demonstrate the photocurrent of the direct electron transfer is enhanced about two fold and with improved stability. Moreover, the assembly strategy without any cross-linker or additional electron mediators permits the cell fabrication and operation much simpler as compared to previous approaches. This work may open new routes for the construction of solar energy conversion systems based on photoactive proteins and graphene materials.

    ABSTRACT: Uptake of nanoparticles by endothelial cells is dependent on shear stress adaptation and flow exposure conditions. Adaptation of primary human umbilical vein endothelial cells (HUVECs) to shear stress for 24 h was associated with reduced internalisation of unmodified 80 nm spherical gold nanoparticles (AuNPs) (mean hydrodynamic size of 99 nm in culture medium) after exposure in flow condition compared with cells that were cultured and exposed in static condition. In static condition, targeting of 80 nm AuNPs conjugated with antibodies against the intracellular adhesion molecule 1 (ICAM-1) (mean hydrodynamic size of 109 nm in culture medium) markedly increased the internalisation of AuNPs in HUVECs that were activated with tumour necrosis factor (TNF), a treatment that markedly increased the surface expression of ICAM-1. Shear stress-adapted and TNF-activated HUVECs, which were exposed in flow condition, had higher association with anti-ICAM-1 AuNPs than cells that were not TNF-activated or exposed to particles in static condition. Hence, shear stress adaptation reduces uptake of unmodified AuNPs and increases the association between anti-ICAM-1 AuNPs and TNF-activated HUVECs.

    ABSTRACT: In this paper, we propose a graphene sensor using two separated single-layer graphenes on a flexible substrate for use as a pressure sensor, such as for soft electronics. The working pressure corresponds to the range in which human perception recognizes surface morphologies. A specific design of the sensor structure drives the piezoresistive character due to the contact resistance between two graphene layers and the electromechanical property of graphene itself. Accordingly, sensitivity in resistance change is given by two modes for low pressure (-0.24/kPa) and high pressure (0.039/kPa) with a crossover pressure (700 Pa). This sensor can detect infinitesimal pressure as low as 0.3 Pa with uniformly applied vertical force. With attachment of the artificial fingerprint structure on the sensor, the detection ability for both the locally generated shear force and actual human touch confirms recognition of the surface morphology constructed by periodic structures.

    ABSTRACT: Metal assisted anodic etching (MAAE) of Si in HF, without H2O2, is demonstrated. Si wafers were coated with Au films, and the Au films were patterned with an array of holes. A Pt mesh was used as the cathode while the anodic contact was made through either the patterned Au film or the back side of the Si wafer. Experiments were carried out on P-type, N-type, P+-type and N+-type Si wafers and a wide range of nanostructure morphologies were observed, including solid Si nanowires, porous Si nanowires, a porous Si layer without Si nanowires, and porous Si nanowires on a thick porous Si layer. Formation of wires was the result of selective etching at the Au-Si interface. It was found that when the anodic contact was made through P-type or P+-type Si, regular anodic etching due to electronic hole injection leads to formation of porous silicon simultaneously with metal assisted anodic etching. When the anodic contact was made through N-type or N+-type Si, generation of electronic holes through processes such as impact ionization and tunnelling-assisted surface generation were required for etching. In addition, it was found that metal assisted anodic etching of Si with the anodic contact made through the patterned Au film essentially reproduces the phenomenology of metal assisted chemical etching (MACE), in which holes are generated through metal assisted reduction of H2O2 rather than current flow. These results clarify the linked roles of electrical and chemical processes that occur during electrochemical etching of Si.

    ABSTRACT: In this paper we discuss the development of a MEMS-based solid state atom source that can provide controllable atom deposition ranging over eight orders of magnitude, from ten atoms per square micron up to hundreds of atomic layers, on a target ~1 mm away. Using a micron-scale silicon plate as a thermal evaporation source we demonstrate the deposition of indium, silver, gold, cooper, iron, aluminum, lead and tin. Because of their small sizes and rapid thermal response times, pulse width modulation techniques are a powerful way to control the atomic flux. Pulsing the source with precise voltages and timing provides control in terms of when and how many atoms get deposited. By arranging many of these devices into an array, one has a multi-material, programmable solid state evaporation source. These micro atom sources are a complementary technology that can enhance the capability of a variety of nano-fabrication techniques.

    ABSTRACT: Two-dimensional (2D) barcodes ubiquitously used to label, track and authenticate objects face increasing challenges of being damaged, altered and falsified. The past effort in nanomaterials has paved way for controlled synthesis of nanomaterials with desired size, shape and function. Due to their extremely small sizes, these nanomaterials are promising as next generation barcodes that can be added into or mixed with objects of interest without being noticed. These barcodes can be effectively read according to their physical properties by manufacturers, law enforcement and security agencies. Meanwhile, nanomaterial-based barcodes are hard to be reverse-engineer or imitate without advanced knowledge and technical expertise. This review describes how nanomaterials can be used as barcodes, discusses advantages and limitations of each type of nanomaterial-based barcodes, and points out ways that could help design and prepare better nanomaterial-based barcodes.

    ABSTRACT: Silicon-based nanomaterials are promising anode materials in lithium-ion batteries (LIBs) due to high theoretical capacity of 4200 mAh g-1, more than 10 times that of commercial graphite. The Si nanoparticles (NPs) with diameter of or below 10 nm generally exhibit enhanced lithium storage properties due to small size and large surface area. However, it is challenging to generate such ultrafine Si NPs by a facile and scalable method. This paper reports a scalable method to fabricate ultrafine Si NPs 5-8 nm in size from dead bamboo leaves (BLs) by thermally decomposing the organic matter, followed by magnesiothermic reduction in the presence of NaCl as a heat scavenger. The ultrafine Si NPs show a high capacity of 1800 mAh g-1 at a 0.2 C (1 C=4200 mA g-1) rate and are thus promising anode materials in lithium-ion batteries. To achieve better rate capability, the BLs-derived ultrafine Si NPs are coated by a thin amorphous carbon layer (Si@C) and then dispersed and embedded in a reduced graphene oxide (RGO) networks to produce Si@C/RGO nanocomposites by a layer-by-layer assembly method. The double protection rendered by the carbon shell and RGO network synergistically yield structural stability, high electrical conductivity and stable solid electrolyte interface during Li insertion/extraction. The Si@C/RGO nanocomposites show excellent battery properties boasting high capability of 1400 mAh g-1 at a high current density of 2 C and remarkable rate performance with capacity retention of 60 % when the current density is increased 20 times from 0.2 to 4 C. This work provides a simple, low cost, and scalable approach enabling the use of BLs waste as a sustainable source for the production of ultrafine Si NPs towards high-performance LIBs.

    ABSTRACT: Pd‒Cu2O core‒shell nanocubes and truncated octahedra with six average sizes for each particle shape have been synthesized from 29-nm Pd nanocubes. The nanocubes have average edge lengths of 64‒124 nm, while the truncated octahedra are 107‒183 nm in opposite tip distance. The core and shell composition and lattice orientation have been determined, showing the formation of single-crystalline Cu2O shells. The surface plasmon resonance (SPR) band from the Pd nanocrystal cores is barely visible. However, the Cu2O shells display facet-dependent optical properties. The Cu2O absorption band for smaller Pd‒Cu2O cubes is consistently more red-shifted than somewhat larger Pd‒Cu2O truncated octahedra. This work again shows that the observed facet-dependent optical phenomenon in metal‒Cu2O core‒shell nanocrystals is derived from the Cu2O shells. Use of 40-nm Pd cubes as cores gave uniform and size-tunable Pd‒Cu2O nanocubes and truncated octahedra that display the Pd SPR band. The Pd SPR band is consistently located at 650 nm for Pd‒Cu2O truncated octahedra, and 670 nm for the cubes despite large variation in the shell thickness. Both the Cu2O absorption and the Pd plasmonic band exhibit facet-dependent optical properties.
