“…As such, alternative methods are continually being investigated to remove the need for the liftout process. 49,50 The "crater-method" (Figure 2b), which takes advantage of the substantially higher milling rates of modern plasma-FIBs, is one such method. 47 However, a significant amount of material is removed using this method and the technique may not be suitable for precious samples.…”

Our Galaxy is vast and awe-inspiring. The stars, planets, and our sun capture our imagination as children. For many of us, that wonder never ceases. It continues to inspire us throughout our careers and prompts us to question the evolution of our Solar System, to question what our place is within it, and how we may maintain longevity in a relatively volatile environment. To answer these questions planetary scientists turn to the study of extraterrestrial material. They analyze meteorites, impact craters, and materials returned by sample return missions for the evidence of events that are known to induce crystallographic and/or elemental changes, or for evidence of extraterrestrial isotopic abundances that point to the age and the original source of the material. Through these studies, we can constrain timelines of events that have occurred throughout the Solar System’s extensive history. Recently, atom probe tomography (APT) has been applied to the study of these materials. APT in correlation with larger-scale analysis techniques has provided insights into isotopic ratios or nanoscale distribution of elements, enriching our knowledge, and minimizing uncertainties in the time frame of critical cosmic events. The continued use of correlative microscopy with APT for the study of planetary science, including studies of small amounts of pristine materials delivered to the Earth by exciting sample return missions, promises to provide key information into the history of our Solar System. Here, we highlight the implications of correlative microscopy with APT for the future pursuits of planetary science, we reflect on the groundbreaking research already achieved, the challenges that have been overcome to achieve these outcomes and the challenges yet to come.

“…Selective material is removed, and the surface topography is modified [11]. The laser ablation process can remove material in micron-level precision at a faster rate [14] and is an effective technique for developing textures [15]. LST using laser ablation phenomena has been successfully utilized by many researchers.…”

“…These are developed by connecting a huge number of units known as monomers. In the area of biomedical applications, these polymers are extensively used [14]. The laser ablation of PTFE films of several thickness and densities has shown that laser treatment of polymertissue will be helpful in clinical tool [79].…”

For generating a texture or pattern on a work surface, one of the emerging processes is laser surface texturing (LST). It is an effective method for producing texture on a work surface. Literature shows that various lasers have been applied to generate textures on the surface of work materials. Recently, LST has shown tremendous potential in the field of biomedical applications. Applying the LST process, the efficacy of the biomaterial has been drastically improved. This paper presents an in-depth review of laser surface texturing for biomedical applications. The effect of LST on important biomaterial has been thoroughly studied; it was found that LST has extreme potential for surface modification of biomaterial and can be utilized for biomedical applications.

“…The reason is mainly due to high milling times, as removal of larger volumes is required, alongside with increasing the likelihood of artifacts related to Ga implantation. Developing alternative methods where tips can be manufactured from the bulk sample without lift-out or Pt welding, increasing sample yield and decreasing the overall preparation time, remain a motivation to explore new approaches (White et al, 2021).…”
