The core of your disc golf game should be a solid midrange driver. The Latitude 64 Core is the perfect solution. It is a versatile disc that can be used for almost any shot. The Core is a super stable disc with a very straight flight path. This is a great disc that provides consistent shots for players of all skill levels. It is good for hyzer shots, as well as turnover drives. This disc will obey your command and consistently react to your throw.

The DMI-OPTO allows Optocore audio over HMA, OpticalCon or ST connectors. Connecting the DMI-OPTO to the DiGiCo OrangeBox (a simple format converter solution), allows the OrangeBox to be added to an Optocore loop and interfaced with another DMI card, giving up to 128 channels of I/O at 48kHz or up to 64 channels of I/O at 96kHz.

The DMI-OPTO can also be used in a 4REA4. When making use of the SD/4REA4 integration, the DMI-OPTO allows an SD console to control I/O that is connected to the 4REA4. The DMI-OPTO is compatible with the Orange Box and the 4REA4.

In a world as competitive for engineers as it is for console owners, you want the best tools you can lay your hands on. You also want a console and audio tools as well thought out for every major application as they are designed for the art and science of sound engineering.

Therefore, nano-engineering the FeAu and ZnO into a single entity would not only exercise the unique properties of FeAu and the ZnO semiconductor, but also generate novel phenomena based on the interaction between FeAu and ZnO at their interfaces. Such nano-assembly can lead to innovative materials which exhibit more broad application prospects owing to their novel optical, magnetic, electrical and chemical properties. In this work, bi-phase dispersible FeAu@ZnO magneto-opto-fluorescent core-shell nanoparticles were synthesized by a modified nanoemulsion process using poly(ethylene glycol)-block-poly(propylene glycol)-block-poly(ethylene glycol) (PEO-PPO-PEO) as the surfactant.

The PEO-PPO-PEO triblock copolymer and families encompass numerous distinct advantages such as biocompatibility, non-charging trait, non-toxicity and aqueous solubility and are frequently used in diverse fields13,14,15,16,17. In nanoemulsion processes, the PEO-PPO-PEO molecules participate in the reactions as the surfactant, playing a role in stabilizing the nanoparticles formed and even acting as a reducing agent. We have investigated a number of multi-functional nanoparticles using PEO-PPO-PEO molecules as the surfactant, such as long-term stable, monosized, highly crystalline FeAu, ZnO-Au and AgZnO nanoparticles6,18,19. The PEO-PPO-PEO-laced FeAu@ZnO nanoparticles as prepared in this work show high crystallinity, monodispersity, bi-phase dispersibility, excellent optical performance both in organic and aqueous medium and outstanding magnetic response. The magnetic hysteresis curves of the nanoparticles were elucidated by the modified Langevin equation, demonstrating the well-defined soft ferromagnetic and/or near superparamagnetic behavior of the core-shell nanoparticles at room temperature. Such bi-phase dispersible core-shell FeAu@ZnO magneto-opto-fluorescent nanoparticles could be of interest for fundamental studies and potential applications.

Figure 4 visually demonstrates the separation and redispersion process of the nanoparticles in water and hexane. Under the influence of an external magnetic field, the FeAu@ZnO nanoparticles in water change from a purplish grey, homogeneous dispersion (Fig. 4a) to a clear, transparent solution, with the nanoparticles collected by a piece of magnet (Fig. 4b). The collected nanoparticles can be easily and reversibly dispersed by agitation after removal of the magnetic field and the above process can be repeated. A similar process happens to the nanoparticles in hexane, as shown in Fig. 4c,d. The color of the solution in Fig. 4a,c is complementary to the corresponding UV-vis absorption to be discussed below. The finding that all PEO-PPO-PEO-laced FeAu@ZnO nanoparticles as prepared could be collected by a magnet, leaving no free Au and ZnO particles visible and thus no co-sedimentation of Au, ZnO and Fe nanoparticles excludes the possibility of separate Au, ZnO and Fe nanoparticles in the FeAu@ZnO preparation and supports the nanostructuring of the FeAu@ZnO nanoparticles. In other words, we performed magnetic separation and found that all nanoparticles were collected by the magnet because the PEO-PPO-PEO-laced FeAu@ZnO core-shell nanoparticles are magnetic and there is no more nanoparticles left-over, so nonmagnetic ZnO nanoparticles are not present in the samples.

We point out that the fact that ZnO possesses environmentally friendly features for photocatalytic applications. But, due to the high rate of electron-hole recombination and visible blindness, however, its applications are somewhat restricted. Nano-engineering both FeAu core and ZnO shell into a single entity could tune down the electron-hole recombination correspondingly and then substantially increases the photocatalytic activity of the material, in addition to easy separation and recovery from the reaction medium as a consequence of the magnetic composition.

Semiconductor-core optical fibres have potential applications in photonics and optoelectronics due to large nonlinear optical coefficients and an extended transparency window. Laser processing can impose large temperature gradients, an ability that has been used to improve the uniformity of unary fibre cores, and to inscribe compositional variations in alloy systems. Interest in an integrated light-emitting element suggests a move from Group IV to III-V materials, or a core that contains both. This paper describes the fabrication of GaSb/Si core fibres, and a subsequent CO2 laser treatment that aggregates large regions of GaSb without suppressing room temperature photoluminescence. The ability to isolate a large III-V crystalline region within the Si core is an important step towards embedding semiconductor light sources within infrared light-transmitting silicon optical fibre.

Semiconductor-core optical fibres are of interest for their nonlinear optical and electro-optical properties, and a variety of demonstration devices have been made, including fibre-based photovoltaic cells, infrared (IR) detectors, and supercontinuum sources1,2,3,4,5. In addition to their role in advanced photonic devices, they can serve as a useful platform for fundamental materials science investigations. Large spatial and temporal temperature gradients can be imposed with a laser to anneal, recrystallise or facilitate reactions in the fibre core. Whether fabrication is by high pressure vapour deposition in fibre pores, or the molten-core fibre drawing method, laser post-processing has proven to be a powerful technique for modifying the properties of the core6,7,8,9. More specifically, significant progress has been reported on the processing of silicon-core fibres, in which optical transmission losses have been reduced7,9,10 and the band-gap energy has been altered6.
