Ultra-high capacity for three-dimensional optical data storage inside transparent fluorescent tape.

In this Letter, we show an ultralarge capacity for three-dimensional optical data storage inside transparent fluorescent tape using the two-photon absorption photo-bleaching method. We can obtain transparent fluorescent tape by means of the simple dip method. We successfully demonstrate recording and reading of six layers of binary data bits with lateral separation of 2 µm and longitudinal layer separation of 3 µm. Thus, this result leads to a storage density of approximately ${80}\;{{\rm Gbits/cm}^3}$80G...


Piezoelectricity in Multilayer Black Phosphorus for Piezotronics and Nanogenerators.

Recently, piezoelectric characteristics have been a research focus for 2D materials because of their broad potential applications. Black phosphorus (BP) is a monoelemental 2D material predicted to be piezoelectric because of its highly directional properties and non-centrosymmetric lattice structure. However, piezoelectricity is hardly reported in monoelemental materials owing to their lack of ionic polarization, but piezoelectric generation is consistent with the non-centrosymmetric structure of BP. Theore...

Powerful 3-μm lasers acousto-optically Q-switched with KYW and KGW crystals.

We report, to the best of our knowledge, the first use of KY(WO) and KG(WO) acousto-optical Q-switches in 3-μm powerful lasers. Q-switches of two different designs (normal incidence with antireflection coatings, and Brewster-angle cut crystals) operate in lasers based on Er:YAG, Cr:Yb:Ho:YSGG, and Cr:Er:YSGG laser crystals. Gain and lifetime of laser crystals significantly influence the regime of Q-switched generation. Er:YAG and Cr:Yb:Ho:YSGG lasers deliver pulses with 10.8 mJ and 17.5 mJ energy, respec...


Making Engineered 3D DNA Crystals Robust.

Engineered 3D DNA crystals are promising scaffolds for bottom-up construction of three-dimensional, macroscopic devices from the molecular level. Nevertheless, this has been hindered by the highly constrained conditions for DNA crystals to be stable. Here we report a method to prepare robust 3D DNA crystals by postassembly ligation to remove this constraint. Specifically, sticky ends at crystal contacts were enzymatically ligated, and the covalent bonds significantly enhanced crystal stability, e.g., being ...

Stretchable, transparent and imperceptible supercapacitors based on Au@MnO nanomesh electrodes.

A highly transparent and stretchable electrode based on a Au nanomesh, electrodeposited with a thin layer of MnO2 with a transparency of 84.7% is introduced. The as-prepared transparent, stretchable, and imperceptible supercapacitor (TSPS) exhibits a specific capacitance of 0.53 mF cm-2 and excellent bending stability, together with high stretchability (up to 160% strain).

An approach to high-throughput growth of submillimeter transition metal dichalcogenide single crystals.

High-throughput growth of large size transition metal dichalcogenide (TMD) single crystals is an important challenge for their applications in the next generation electronic and optoelectronic integration devices. Here we report the high-throughput growth of submillimeter monolayer TMD single crystals by two-stage space confined chemical vapor deposition, where the nucleation density of TMD crystals is significantly decreased for the growth of large size monolayer crystals by the space confinement effect. M...

Discrete Lorentz symmetry and discrete spacetime translational symmetry in two- and three-dimensional crystals.

As is well known, crystals have discrete space translational symmetry. It was recently noticed that one-dimensional crystals possibly have discrete Poincar\'{e} symmetry, which contains discrete Lorentz and discrete time translational symmetry as well. In this paper, we classify the discrete Poincar\'{e} groups on two- and three-dimensional Bravais lattices. They are the candidate symmetry groups of two- or three-dimensional crystals, respectively. The group is determined by an integer generator $g$, and it...

Ultrafast 27 GHz cutoff frequency in vertical WSe Schottky diodes with extremely low contact resistance.

Ultra-thin two-dimensional semiconducting crystals in their monolayer and few-layer forms show promising aspects in nanoelectronic applications. However, the ultra-thin nature of two-dimensional crystals inevitably results in high contact resistance from limited channel/contact volume as well as device-to-device variability, which seriously limit reliable applications using two-dimensional semiconductors. Here, we incorporate rather thick two-dimensional layered semiconducting crystals for reliable vertical...

Active Phagocytosis and Diachronic Processing of Calcium Oxalate Monohydrate Crystals in an in vitro Macrophage Model.

Transparent actuator made by highly-oriented carbon nanotube film for bio-inspired optical systems.

Transparent actuator can be used in variable-focus lens, tactical displays and so on. However, previous transparent actuators made with dielectric elastomer mostly required high driving voltages (> 1000 V) for actuation. In this work, we propose a new kind of low-voltage-driven transparent actuator, which is made with polymer and single-layer highly-oriented carbon nanotube (HOCNT) film composites, fully utilizing the favorable conductivity and high transparency of HOCNT film. The HOCNT-based transparent ac...

Rb4Li2TiOGe4O12: A Titanyl Nonlinear Optical Material with Widest Transparency Range.

Practical mid-infrared (MIR) coherent light beams generated by frequency conversion in nonlinear optical (NLO) crystals are indispensable in time-resolved infrared vibrational spectroscopy, remote light detection and ranging, and free space communications. Herein, a new titanyl germanate Rb4Li2TiOGe4O12 (RLTG) MIR NLO crystal was obtained by heavier element substitution. It features a complicated structure network composed of the compressed TiO5 square pyramids and distorted GeO4 tetrahedra, separated by Rb...

Solution-Processed Polymeric Thin Film as the Transparent Electrode for Flexible Perovskite Solar Cells.

In the past ten years, perovskite solar cells (PSCs) were arising as a new generation of low-cost solar technology for renewable energy generation. More than 25 % of power conversion efficiency (PCE) has been reported from PSCs on the rigid indium tin oxide (ITO)/glass electrode. However, PSCs on the flexible solution-processed transparent electrode has still been a challenge to date. In this work, we report solution-processed transparent polymeric this film as the electrode for flexible solution-processed ...

Quantum Time Crystals from Hamiltonians with Long-Range Interactions.

Time crystals correspond to a phase of matter where time-translational symmetry (TTS) is broken. Up to date, they are well studied in open quantum systems, where an external drive allows us to break discrete TTS, ultimately leading to Floquet time crystals. At the same time, genuine time crystals for closed quantum systems are believed to be impossible. In this study we propose a form of a Hamiltonian for which the unitary dynamics exhibits the time crystalline behavior and breaks continuous TTS. This is ba...

Elastic properties of the molecular crystals of hydrocarbons from first principles calculations.

I studied the elastic properties of oligoacenes and polycyclic aromatic hydrocarbons crystals within the framework of density functional theory with van der Waals interactions. The full sets of elastic constants were computed. The computed parameters have good agreement with experimental data. The study of four forms (α, β, γ and dimeric) demonstrate that the stacking of molecules leads to different character of interaction between molecules. Crystals with dimeric form have lower anisotropy. If symmetry ...

New method for immobilising diverse proteins onto cubic micro-protein polyhedrin crystals.

Cypovirus is an insect virus that is encapsulated in stable cubic protein crystals composed of polyhedrin protein produced in virus-infected cells. Molecular technology developed over the last decade is now able to immobilise proteins of interest on polyhedrin crystals. Modified polyhedrin crystals can be used in cell cultures for implantation in animals and vaccines, among other applications. However, this technique does not work for some proteins. Here, we developed and tested an alternative approach for ...

Interaction Screening by Kendall's Partial Correlation for Ultrahigh-dimensional Data with Survival Trait.

In gene expression and genome-wide association studies, the identification of interaction effects is an important and challenging issue owing to its ultrahigh-dimensional nature. In particular, contaminated data and right censored survival outcome make the associated feature screening even challenging.

Facile and noninvasive passivation, doping and chemical tuning of macroscopic hybrid perovskite crystals.

Halide vacancies and associated metallic lead (Pb°) observed at the surface and deep inside macroscopic organolead trihalide perovskite crystals is removed through a facile and noninvasive treatment. Indeed, Br2 vapor is shown to passivate Br-vacancies and associated Pb° in the bulk of macroscopic crystals. Controlling the exposure time can markedly improve the overall stoichiometry for moderate exposures or introduce excessive bromide for long exposures, resulting in p-doping of the crystals. In the low ...

Non-contact method of thickness measurement for a transparent plate using a laser auto-focus scanning probe.

In this paper we propose a novel non-contact method of thickness measurement for a transparent plate using a laser auto-focus scanning (LAFS) probe. Through the analysis of the focus error signal (FES) from the actual specimen's upper and lower surface reflectances, a measurement model is introduced to find the best focus position on the corresponding surface of the transparent plate. Thus, the thickness of a specimen can be obtained. Herein, the LAFS probe measurement characteristics by auto-searching the ...

Performance of nearly fixed offset asymmetric channel-cut crystals for X-ray monochromators.

X-ray double-crystal monochromators face a shift of the exit beam when the Bragg angle and thus the transmitted photon energy changes. This can be compensated for by moving one or both crystals accordingly. In the case of monolithic channel-cut crystals, which exhibit utmost stability, the shift of the monochromated beam is inevitable. Here we report performance tests of novel, asymmetrically cut, channel-cut crystals which reduce the beam movements by more than a factor of 20 relative to the symmetric case...

Uncovering the Indium Filament Revolution in Transparent Bipolar ITO/SiOx/ITO Resistive Switching Memories.

Transparent Resistive switching random access memory (ReRAM) is of interest for the future integrated invisible circuitry. However, poor understanding of its working mechanism in transparent ReRAMs with indium tin oxide (ITO) electrode is still a critical problem and will hinder its widespread applications. To reveal the actual working mechanism in transparent ReRAMs with ITO electrode, we investigate the transparent ITO/SiOx/ITO memory devices (~82% transmittance in the visible region) and compare it with ...

The influence of temperature and component proportion on stability, sensitivity, and mechanical properties of LLM-105/HMX co-crystals via molecular dynamics simulation.

Based on molecular dynamics (MD) simulation, the binding energy, cohesive energy density (CED), bond length, and mechanical parameters were calculated for 2,6-diamino-3,5-dinitropyrazine-l-oxide (LLM-105) crystal, octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX) crystal, and their co-crystals under different temperatures. Three LLM-105/HMX patterns were constructed to investigate the influence of component proportion on structures and properties of co-crystals, in which the mole ratios of LLM-105 and ...

Hydrothermal synthesized UV-resistance and transparent coating composited superoloephilic electrospun membrane for high efficiency oily wastewater treatment.

As oily wastewater issues continue to grow, the treatment of oily wastewater has become urgent an emergency. However, present solutions are restricted by the limited performance of materials. An UV-resist and transparent coating consisting of PDMS and ZnO decorated on a highly stable and self-standing polyimide is reported in this work as a potential solution. The obtained fibrous membranes not only allow high-efficiency (higher than 99%) oily wastewater separation but also show superior UV-resistant activi...

Two-dimensional MoX2 (X = S, Se) films were vertically grown on highly rough transparent conducting F-doped SnO2 glass substrates for the first time and successfully used as photogenerated carrier-guiding layers (CGLs) in transparent hydrogenated amorphous silicon (a-Si:H) thin film solar cells (TFSCs). The MoSe2 CGL layers could be grown at 530 °C using thermally cracked small Se-molecules on transparent FTO glass substrates and significantly improved cell performance. A transparent cell transmitting 26.0...
