Surface plasmons in a nanostructured black phosphorus flake.

Recent rediscovered layered material-black phosphorous with a puckered honeycomb atomic structure has experienced an upsurge in demand owing to its exotic physical properties such as layer-independent direct bandgap and linear dichroism. This Letter presents plasmonic properties of the nanostructured BP flake and its unprecedented capability of wide-band photon manipulation within the deep subwavelength scale. Owing to its anisotropic characteristic in band structure and moderate mobility, a strong layer nu...


Spatiotemporal Evolution of Coherent Elastic Strain Waves in a Single MoS2 Flake.

We use bright-field imaging in an ultrafast electron microscope to spatiotemporally map the evolution of photoexcited coherent strain waves in a single, micrometer-size flake of MoS2. Following in situ femtosecond photoexcitation, we observe individual wave trains emerge from discrete nanoscale morphological features and propagate in-plane along specific wave vectors at approximately the speed of sound (7 nm/ps). Over the span of several-hundred picoseconds, the 50-GHz wave trains (20-ps periods) are observ...

Promoting power density by cleaving LiCoO2 into nano-flake structure for high performance supercapacitor.

LiCoO2 (LCO) usually can deliver high energy density but low power density in Li-ion batteries (LIBs). Whether LCO could be used as electrode material for high-performance supercapacitors is dependent on promoting its power density. Owing to Faradaic redox reactions taking place on its surfaces or inside crystals through ion intercalation/deintercalation from the surfaces, increasing the specific area of LCO is a key factor to promote its rate capability. Herein, we report a facile strategy to prepare LCO n...


Giant valley-isospin conductance oscillations in ballistic graphene.

At high magnetic fields the conductance of graphene is governed by the half-integer quantum Hall effect. By local electrostatic gating a pn-junction perpendicular to the graphene edges can be formed, along which quantum Hall channels co-propagate. It has been predicted that if only the lowest Landau level is filled on both sides of the junction, the conductance is determined by the valley (isospin) polarization at the edges and by the width of the flake. This effect remained hidden so far due to scattering ...

Non-Planar nCyclo-1,8-carbazolylenes (n = 3,4,6) and 3Cyclo-1,8-carbazolylenyl B, P, PO, SiPh Complexes.

A new family of non-planar heterocyclic molecules consisting of carbazoles was created. A bowl-shaped cyclodimer, a flake-shaped cyclotrimer, a double-decker-ring-shaped cyclotetramer and a cyclohexamer were synthesized by Ni(0)-mediated one-shot cyclo-oligomerization of 1,8-dibromocarbazole, and were named [n]cyclo-1,8-carbazolylenes (n = 3,4,6). [3]Cyclo-1,8-carbazolylene was found to act as a trivalent tridentate ligand for heteroatoms (B, P, Si), giving flake-shaped complexes. The boron derivative acted...

Inducing and Manipulating Heteroelectronic States in a Single MoS_{2} Thin Flake.

By dual gating a few-layer MoS_{2} flake, we induce spatially separated electronic states showing superconductivity and Shubnikov-de Haas (SdH) oscillations. While the highly confined superconductivity forms at the K/K^{'} valleys of the topmost layer, the SdH oscillations are contributed by the electrons residing in the Q/Q^{'} valleys of the rest of the bottom layers, which is confirmed by the extracted Landau level degeneracy of 3, electron effective mass of 0.6m_{e}, and carrier density of 5×10^{12} ...

Crude Ecklonia cava Flake Extracts Attenuate Inflammation through the Regulation of TLR4 Signaling Pathway in LPS-Induced RAW264.7 Cells.

We investigated the beneficial effects of the crude Ecklonia cava flake (CEF), which is a residual product after polyphenol extraction from Ecklonia cava, on inflammation in LPS-stimulated RAW264.7 cells. A group of five different CEF extracts was obtained by a preparation process using water, hydrochloric acid or temperature. We observed that large-size (>19 kDa) CEF extract, which was extracted with water at 95 °C (CEF-W, 95 °C), suppressed the production of inflammatory cytokines by inhibiting its mRNA...

Optical gating of black phosphorus for THz detection.

Photoconductive antennas are widely used for time-resolved detection of THz pulses. In contrast to photothermoelectric or bolometric THz detection, the coherent detection allows direct measurement of the electric field transient of a THz pulse, which contains both, spectral and phase information. In this letter we demonstrate for the first time photoconductive detection of free-space propagating THz radiation with thin flakes of a van der Waals material. Mechanically exfoliated flakes of black phosphorus ar...

Tracing social interactions in Pleistocene North America via 3D model analysis of stone tool asymmetry.

Stone tools, often the sole remnant of prehistoric hunter-gatherer behavior, are frequently used as evidence of ancient human mobility, resource use, and environmental adaptation. In North America, studies of morphological variation in projectile points have provided important insights into migration and interactions of human groups as early as 12-13 kya. Using new approaches to 3D imaging and morphometric analysis, we here quantify bifacial asymmetry among early North American projectile point styles to be...

Probing low-energy hyperbolic polaritons in van der Waals crystals with an electron microscope.

Van der Waals materials exhibit intriguing structural, electronic, and photonic properties. Electron energy loss spectroscopy within scanning transmission electron microscopy allows for nanoscale mapping of such properties. However, its detection is typically limited to energy losses in the eV range-too large for probing low-energy excitations such as phonons or mid-infrared plasmons. Here, we adapt a conventional instrument to probe energy loss down to 100 meV, and map phononic states in hexagonal boron ...

Thinking Big.

Most public health measures languished in the 85th Texas Legislature, but those for mental health care stood out as a giant exception. Lawmakers passed more than a dozen bills aimed at improving mental health care. And at a time when most state budgets were slashed, funding for mental health care rose - by a lot.

Paul of Aegina (ca 625-690 ad), Reconstructing Male Gynecomastia.

Paul of Aegina thrived with his innovative operations, practically creating a kind of a new surgical school. He had deeply believed in human's body perfection introducing a series of cosmetic operations. Among them stood the male's breasts reconstruction in the case of pseudo-gynecomastia. His intervention was replicated by both the western Europeans and the Arabs.

Bio-Tunable Nanoplasmonic Filter on Few-Layer MoS2 for Rapid and Highly Sensitive Optoelectronic Cytokine Immunosensing.

Monitoring of the time-varying immune status of a diseased host often requires rapid and sensitive detection of cytokines. Metallic nanoparticle-based localized surface plasmon resonance (LSPR) biosensors hold promise to meet this clinical need by permitting label-free detection of target biomolecules. These biosensors, however, continue to suffer from relatively low sensitivity as compared to conventional immunoassay methods that involve labelling processes. Their response speeds also need to be further im...

Prevention of Post-ERCP Pancreatitis Is More Than Just Suppositories and Stents.

In this issue of the Journal, Professor Elmunzer provides an outstanding overview of the variable methods of prevention of post-ERCP pancreatitis (PEP) (1). We all recognize the importance of this topic given its morbidity for our patients. His review succinctly summarizes a wealth of both old and new data underscoring previously identified risk factors for PEP which have stood the test of time. In addition, newer interventions are appraised and placed in an appropriate context. This article is protected by...

The Clue.

As I stood outside of Carlos's room, I felt caught on the horns of a dilemma. It seemed impossible to truly "be there" for Carlos without sacrificing my other intern duties. This tension pervaded much of my residency training, as I often found myself spending more time completing chart notes, answering pages, and giving sign out than I did at the bedside with my patients. I knew I had a duty to "do my job"-I could not let my team down. But what about my duty to Carlos, a duty to act on my intuition and try ...

Strong electric wave response derived from the hybrid of lotus roots-like composites with tunable permittivity.

Lotus roots-like NiO/NiCo2O4 hybrids derived from Metal-organic frameworks (MOFs) are fabricated for the first time by using flake NiCo-MOF precursors as reactant templates. It was found that a thin sample consisting of 60 wt % NiO/NiCo2O4 hybrids in the wax matrix exhibited an effective microwave absorption bandwidth of 4.2 GHz at the thickness of 1.6 mm. The highest reflection loss of -47 dB was observed at 13.4 GHz for a sample with a thickness of 1.7 mm. Results obtained in this study indicate tha...

HIV/AIDS knowledge, attitudes and behaviour of persons with and without disabilities from the Uganda Demographic and Health Survey 2011: Differential access to HIV/AIDS information and services.

Uganda is among the first to use the Washington Group Short Set of Questions on Disability to identify persons with disabilities in its Demographic and Health Survey. In this paper, we review the HIV Knowledge, Attitudes and Behaviour component of the 2011 Ugandan Demographic and Health Survey, analysing a series of questions comparing those with and without disabilities in relation to HIV/AIDS knowledge, attitudes and practices. We found comparable levels of knowledge on HIV/AIDS for those with and those w...

Modulation of Quantum Tunneling via a Vertical Two Dimensional Black Phosphorus and Molybdenum Disulfide PN Junction.

Diverse diode characteristics were observed in two-dimensional (2D) black phosphorus (BP) and molybdenum disulfide (MoS2) heterojunctions. The characteristics of a backward rectifying diode, a Zener diode and a forward rectifying diode were obtained from the heterojunction through thickness modulation of the BP flake or back gate modulation. Moreover, tunnel diode with a precursor to negative differential resistance (NDR) can be realized by applying dual gating with a solid polymer electrolyte layer as a to...

Acute effects of whole body vibration on balance in persons with and without chronic ankle instability.

Chronic ankle instability (CAI) is a common condition following ankle injury that is associated with compromised balance. Whole body vibration training (WBVT) programmes are linked with improved balance and function in athletic and non-athletic populations and may improve balance in CAI. Twelve healthy and seven CAI participants completed two randomly assigned interventions. Two Power Plate® platforms were attached back to back using a Theraband®. Participants stood on the active plate and inactive plate ...

The origin of the Acheulean. Techno-functional study of the FLK W lithic record (Olduvai, Tanzania).

The Acheulean materials documented in FLK West dated c. 1.7 Ma. are the focus of the present work. An original techno-functional approach is applied here to analyze the origin of Acheulean tools. According to the results, these tools were employed in different functional contexts in which tasks of different durations that transformed resources with different resistances were carried out. The exploitation of large and resistant resources suggests that the economic mechanism governing the manufacture of these...

Ventilatory response to carbon monoxide during exercise in hypoxia and hypercapnia.

We tested if the addition of CO to inspired gases with different inspired O2 and CO2 fractions (FIO2 and FICO2) stimulates ventilation at rest or during submaximal exercise. We measured minute ventilation (VE) in goats breathing combinations of FIO2 ranging from 0.21 to 0.06 and FICO2 from 0 to 0.05, both with and without inspired CO resulting in carboxyhemoglobin fractions (FHbCO) of 0.02 (no CO added), 0.15, or 0.45. We did this while they stood on a treadmill, walked at 1.4, or trotted at 2.5ms(-1). Hypo...

Does movement influence representations of time and space?

Embodied cognition posits that abstract conceptual knowledge such as mental representations of time and space are at least partially grounded in sensorimotor experiences. If true, then the execution of whole-body movements should result in modulations of temporal and spatial reference frames. To scrutinize this hypothesis, in two experiments participants either walked forward, backward or stood on a treadmill and responded either to an ambiguous temporal question (Experiment 1) or an ambiguous spatial quest...

Three-dimensional Graphene with MoS 2 Nanohybrid as Potential Energy Storage/Transfer Device.

Portable and matured energy storage devices are in high demand for future flexible electronics. Flowery shaped MoS2 nanostructures with porous and flake like morphology was used to study the supercapacitive nature with specific capacitance (C sp ) of 169.37F/g, the energy density of 28.43 Wh/Kg and power density of 10.18 W/Kg. This nanoflower like architecture was decorated on 3D-graphene on Graphite electrode to design the solid-state-supercapacitor prototype device of dimensions of 23.6 × 22.4 ...

Layer-Tunable Phosphorene Modulated by the Cation Insertion Rate as a Sodium-Storage Anode.

Liquid phase exfoliation of few-layer phosphorene (FL-P) is extensively explored in recent years. Nevertheless, their deficiencies such as ultralong sonication time, limited flake size distribution, and uncontrollable thicknesses are major hurdles for the development of phosphorene-based materials. Herein, electrochemical cationic intercalation has been introduced to prepare phosphorene, through which large-area FL-P without surface functional groups can be efficiently attained (less than 1 h). More importa...

An exercise in brain genoarchitectonics: Analysis of AZIN2-Lacz expressing neuronal populations in the mouse hindbrain.

We examined in detail the distribution of AZIN2 (antizyme inhibitor 2) expression in the adult mouse hindbrain and neighboring spinal cord. AZIN2, similar to previously known AZIN1, is a recently-discovered, a functional paralog of ornithine decarboxylase (ODC). Due to their structural similarity to ODC, both AZIN1 and AZIN2 counteract the inhibitory action of 3 known antizymes (AZ1-3) on the ODC synthesis of polyamines, thus increasing intracytoplasmic levels of polyamines. AZIN2 is strongly, but heterogen...
