“…The IR spectra of the PLA-prepared samples are presented in Figure 7a. The band observed for both samples (red and blue curves) at 500 cm −1 is characteristic of valence vibrations of the Zn-O band [13]. Apart from Zn-O vibrations, two wide and intense bands in the range of 3750–2800 cm −1 and 1630–1200 cm −1 are observed for both samples, as well as several less pronounced bands between ~1000 and 600 cm −1 .…”

“…In addition to PLA in liquids [4,5,6,7,8,9,10], more recently, the PLA approach in gases or vacuum has also been applied in nanomaterial preparation, including Zn-based NPs [11,12]. In the case of PLA in air [13]: (1) target surface temperature increases, reaching melting and vaporization points; (2) plasma is formed due to interaction between the laser pulse and vaporized material; (3) ZnO NPs are formed in the plasma plume as a result of reactions between excited zinc species and ionized oxygen molecules from air, as well as outside the plume due to diffusion, where plasma ions interact with unexcited oxygen molecules. Finally, the formed ZnO NPs are deposited onto the substrate.…”

Here, we report on ZnO nanoparticles (NPs) generated by nanosecond pulsed laser (Nd:YAG, 1064 nm) through ablation of metallic Zn target in water and air and their comparative analysis as potential nanomaterials for biomedical applications. The prepared nanomaterials were carefully characterized in terms of their structure, composition, morphology and defects. It was found that in addition to the main wurtzite ZnO phase, which is conventionally prepared and reported by others, the sample laser generated in air also contained some amount of monoclinic zinc hydroxynitrate. Both nanomaterials were then used to modify model wound dressings based on biodegradable poly l-lactic acid. The as-prepared model dressings were tested as biomedical materials with bactericidal properties towards S. aureus and E. coli strains. The advantages of the NPs prepared in air over their counterparts generated in water found in this work are discussed.

“…Propulsion systems are also important approaches to ADR and usually consist of chemical propulsion, hybrid propulsion, electrical propulsion, laser propulsion, and others [2,34]. A propulsion system generally consists of a power source and a propulsor to generate propulsive force for ΔV requirements of orbit transfer or debris deorbiting, and its performance is strongly affected by system volume, system mass, and cost of the propulsion unit [35].…”

“…Laser propulsion is a contactless removal approach [10] and can be segmented into two kinds of common approaches, i.e., pulse laser propulsion (PLP) and continuous wave propulsion (CWP) [34]. Based on the ground-or space-based energy source, counterforce is exerted on the material surface of the target object for momentum transition; PLP therefore has a very outstanding merit compared to all other propulsion approaches, which can increase the payloads and decrease the launch costs of space missions [34]. Robotic arm technique has been developed rapidly and was initially used for on-orbit servicing missions [10].…”

Geomagnetic Energy Approach to Space Debris Deorbiting in a Low Earth Orbit

The space debris removal problem needs to be solved urgently. Over 70% of debris is distributed between the 500 km and 1000 km low Earth orbits (LEO), and existing methods may be theoretically feasible but are not the high-efficiency and low-consumption methods for LEO debris removal. Based on the torque effect of a static magnet interacting with the geomagnetic field, a new spin angular momentum exchange (SAME) method by geomagnetic excitation (without working medium consumption) for LEO active debris deorbiting is proposed. The LEO delivery capability of this method is researched. Two kinds of spin angular momentum accumulation (SAMA) strategies are proposed. Then through numerical simulation under the dipole model and International Geomagnetic Reference Field (IGRF11) model, the results confirm the physical feasibility and basic performance of the proposed method. The method can be applied to the regions of the LEO below 1000 km with different altitudes/inclinations and eccentricities, and with existent magnetorquer technology, only several days of preparation is required for about 104 m·kg mechanism-scale-debris-mass deorbiting, which can be used for deorbiting missions in debris-intensive areas (altitude≤1000 km); without consideration of external effects on the geomagnetic field distribution, it has the same deorbiting capability with that of the LEO below 1000 km when the altitude is over 1000 km. Besides, the method is characterized by explicit mechanism, flexible control strategy and application, and low dependence on the scale. Finally, the key technology requirements and future application of LEO active debris removal and on-orbit delivery by using SAME are prospected.

“…Thin film coating using pulsed laser deposition (Dellasega et al, 2017), spectrochemical analysis by means of laser induced breakdown spectroscopy Siozos et al (2017), Koral et al (2018), propulsion of space craft using laser ablation thrusters (Yu et al, 2018), as well as inertial fusion confinement (Strozzi et al, 2017), are all based upon the ruling mechanisms behind the formation and expansion of laser induced plasmas (LIP). Whether for practical applications or for the ones which are still at the experimental stage, fundamental research aiming at understanding how the target nature (thermophysical and optical properties) as well as the laser beam properties and the background environment impact the initial stage of the plasma plume creation and its dynamic, remains crucial.…”

The present work is motivated by the numerous applications of short lasers–ceramics interaction. It aims at applying a newly developed model to investigate the dynamic of laser-induced plasmas from a ceramic material into a helium gas under atmospheric pressure. To have a better understanding of the link between the material properties, the plume characteristics and its interaction with the laser beam, a thorough examination of the entire ablation processes is conducted. Comparison with the behavior of laser-induced plumes under the same conditions from a pure material is shown to have a key role in shedding the light on what monitors the plume expansion in the background environment. Plume temperatures, velocities, ionization rates as well as elemental composition have been presented and compared under carefully chosen relevant conditions. This study is of interest for laser matter applications depending on the induced plasmas dynamics and composition.
