    Abstract

    This study investigates the feasibility of in-situ manufacturing of a functionally graded metallic-regolith. To fabricate the gradient, digital light processing, an additive manufacturing technique, and spark plasma sintering were selected due to their compatibility with metallic-ceramic processing in a space environment. The chosen methods were first assessed for their ability to effectively consolidate regolith alone, before progressing regolith directly onto metallic substrates. Optimized processing conditions based on the sintering temperature, initial powder particle size, and different compositions of the lunar regolith powders were identified. Experiments have successfully proven the consolidation of lunar regolith simulants at 1050°C under 80 MPa with digital light processing and spark plasma sintering, while the metallic powders can be fully densified at relatively low temperatures and a pressure of 50 MPa with spark plasma sintering. Furthermore, the lunar regolith and Ti6Al4V gradient was proven to be the most promising combination. While the current study showed that it is feasible to manufacture a functionally graded metallic-regolith, further developments of a fully optimized method have the potential to produce tailored, high-performance materials in an off-earth manufacturing setting for the production of aerospace, robotic, or architectural components.

    "THz Spintronic Emitters: A review on achievements and future challenges"

    By Evangelos Th. Papaioannou and René Beigang

    From the journal - Nanophotonics



    Abstract

    The field of THz spintronics is a novel direction in the research field of nanomagnetism and spintronics that combines magnetism with optical physics and ultrafast photonics. The experimental scheme of the field involves the use of femtosecond laser pulses to trigger ultrafast spin and charge dynamics in thin films composed of ferromagnetic and nonmagnetic thin layers, where the nonmagnetic layer features a strong spin–orbit coupling. The technological and scientific key challenges of THz spintronic emitters are to increase their intensity and to shape the frequency bandwidth. To achieve the control of the source of the radiation, namely the transport of the ultrafast spin current is required. In this review, we address the generation, detection, efficiency and the future perspectives of THz emitters. We present the state-of-the-art of efficient emission in terms of materials, geometrical stack, interface quality and patterning. The impressive so far results hold the promise for new generation of THz physics based on spintronic emitters.


    Introduction

    Terahertz (THz) radiation covers a broad bandwidth of the electromagnetic spectrum from 100 GHz to 30 THz [1] lying between the microwave and the far infrared band. THz radiation is utilized by a number of scientific and research communities, ranging from chemistry and medicine to physics and material sciences. Recent technological innovations in optics and photonics enable THz research and technology to address an increasingly wide variety of applications [2], [3]: information and communications technology; spectroscopy and imaging, biology, medical and pharmaceutical sciences; nondestructive evaluation (material and circuitry diagnosis), security (detection of drugs and explosives), global environmental monitoring, THz sensor networks, ultrafast computing and astrophysics. Despite all that, the THz region of the electromagnetic spectrum is still an comparatively unexplored region due to the lack of strong and broadband THz emission sources and sensitive detectors.


    Here, we review the recent developments in nanomagnetism and spintronics that allowed the first usage of ultrafast spin physics for THz emission. The physical mechanism of the THz radiation of spintronic emitters is based on the inverse spin Hall effect [4] and appears in multilayer heterostructures that consist of ferromagnetic (FM) and nonmagnetic (NM), usually heavy metal, layers. When illuminated by ultrafast femtosecond (fs) laser pulses, spin-polarized electrons are excited in the FM layer and subsequently diffuse as a spin current into the NM layer. Due to the inverse spin Hall effect (ISHE), the spin current is converted into a transient transverse charge current in the NM layer resulting in THz emission [4]. This new source of THz radiation is an emerging topic subject to intensive research. The efficiency of such emitters is in some cases comparable with established types of THz sources (for example, with nonlinear crystals) [5]. The engineering of THz emission is the main technological and scientific challenge and is currently the target of many research activities. In this review article, we highlight and examine the different strategies that have been followed in order to explore the properties of the emitted THz signal, like THz amplitude and bandwidth, e.g., different material compositions of FM/NM systems with a variety of thicknesses, spintronic emitters in different geometrical stacking order using different layers and patterned structures, different substrates, interface materials and quality of interfaces and dependence on the excitation wavelength. First, we highlight the radiation mechanism and the experimental way to measure the emitted THz radiation. We explore the current trends to engineer the properties of the THz emission and we discuss the future challenges to integrate spintronic emitters in THz devices. We finally explore the potential of the emitter to extend the THz field and widen its applications. The reader should notice that this work summarizes only experimental results from the last couple of years and does not review theoretical models and calculations of the spin transport in magnetic heterostructures. In addition, we focus on the mechanism of THz generation from the ISHE and we will not deal in depth with other novel sources of THz radiation originating from other mechanisms like anomalous Hall effect or Rashba interfaces, since both are much less effective as THz sources compared to the ISHE mechanism.

  • Artificial intelligence is breaking patent law



    Artificial intelligence (AI) is being used to aid vaccine development, drug design, materials discovery, space technology and ship design — creating one of the biggest threats patent systems have faced. “If courts and governments decide that AI-made inventions cannot be patented, the implications could be huge,” argue legal scholar Alexandra George and AI researcher Toby Walsh. They propose that governments safeguard innovation by adopting bespoke intellectual-property law — AI-IP — that protects AI-generated inventions.

    This year is rich in international events in our field. All around the

    planet of authors are already preparing presentations. Including in

    France. Our honorary president Jean-Paul Bibérian is kind to us

    present in preview the subjects on which it will have to communicate this summer (ICCF24)

    during a virtual meeting scheduled for:

    Friday, June 24 from 7 p.m. to 8 p.m.

    This meeting will also be an opportunity to discuss issues that are important to you.

    heart, as well as to discuss the organization of the next RNBE2022.

  • Researchers have uncovered a methane-hydrogen compound containing more than 50% hydrogen, a finding that could help scientists better understand the interior dynamics of planets, including Earth.


    In the outer Solar System, methane- and hydrogen-based compounds are the most common small molecules aside from water, so their interaction in extreme conditions is interesting to scientists. Signatures of methane-hydrogen compounds have appeared in geoscience and materials science studies. But, despite the ubiquity of these substances, they have been experimentally ignored for decades. Now, Ross Howie from the University of Edinburgh, UK, and his colleagues have explored the properties of a variety of methane-hydrogen molecules, finding previously unobserved hydrogen-rich forms of these compounds [1]. The discovery could help in better understanding the evolution and interior dynamics of Neptune, Uranus, Earth, and other planets where methane-hydrogen compounds are found.


    To form their methane-hydrogen compounds, Howie and colleagues used a diamond anvil cell—a device that compresses materials to extreme pressures. Trapping about a nanoliter of methane-hydrogen gas between two diamond tips, the team squeezed it down until it formed a solid compound with a diameter of roughly that of a human hair. In x-ray diffraction and optical spectroscopy experiments, the team determined the structure of the resulting high-pressure compounds.


    Above pressures of 5 GPa, the team observed the formation of methane-hydrogen compounds rich in hydrogen. One of those compounds, (CH4)3(H2)25, which is made up of 3 methane molecules and 25 hydrogen molecules, contained 51% hydrogen by weight, the most hydrogen of any known substance.

  • To read these researchers one would think that life bricks were created in an ascending process.

    From the smallest atom to heavier atoms in a therefore exothermic fusion process.

    For my part, I expect it should not possible to create superstructured molecules like DNA and create excess heat at the same time. From a stability point of view, this seems in opposition.

    I will rather see these H, C, O and N created by processes descending therefore by endothermic fission starting from the peak of the iron/nickel towards increasingly light atoms.

    My favorite is calcium from stones.


    PS: I forgot to specify, those would be the cosmic rays in particular UV which would give the necessary energy by resonant behaviors.
