Absorption waves produced by CO2 laser ablation [PDF]

open access: yes, 2006
A requirement for efficient pulsed laser propulsion from ground to LEO is the achievement of a specific impulse of up to 800 s at a jet efficiency of at least 50%.

A thermal model for nanosecond pulsed laser ablation of aluminum

open access: yesAIP Advances, 2017
In order to simulate the nanosecond pulsed laser ablation of aluminum, a novel model was presented for the target ablation and plume expansion. The simulation of the target ablation was based on one-dimensional heat conduction, taking into account ...

Theoretical and experimental study of dual-fiber laser ablation for prostate cancer. [PDF]

open access: yesPLoS ONE, 2018
Single-fiber laser treatment of the prostate has been widely accepted in the clinic due to its minimal invasiveness and high controllability. However, for large tumors, multiple insertions of the laser probe would be needed to achieve full coverage of ...

Discerning protein pools by selective staining with self‐labeling tags

open access: yesFEBS Letters, EarlyView.
Cell surface proteins have an intra‐ and extracellular pool. Combining genetic fusion to self‐labeling tags that can be addressed with small molecule fluorophores allows separating these pools. We highlight recent developments and techniques for state‐of‐the‐art interrogation of cell surface proteins in the complex tissue setting.

CO2 Laser Ablation Area Scaling and Redeposition on Flat Polyoxymethylene Targets [PDF]

open access: yes, 2010
One of the remaining subjects of interest for laser ablation propulsion study is whether special benefits or challenges exist when applying a particularly large or small laser spot area to a target. This subject is of high importance for topics including

Laser Cavitation Peening and Its Application for Improving the Fatigue Strength of Welded Parts

open access: yesMetals, 2021
During conventional submerged laser peening, the impact force induced by laser ablation is used to produce local plastic deformation pits to enhance metallic material properties, such as fatigue performance.

Peripheral lysosomes recruit PLEKHG3 to focal adhesions and restrain protrusion dynamics

open access: yesFEBS Letters, EarlyView.
Proximity‐dependent labeling at the LAMTOR complex revealed the Rho GEF PLEKHG3 as a lysosome‐proximal protein directing the study toward the influence of lysosome positioning on actin dynamics and cell motility. We show that PLEKHG3 colocalizes with lysosomes at focal adhesion sites and observe that forced peripheral dispersion of lysosomes hinders ...

Possible explanations for different surface quality in laser cutting with 1 micron and 10 microns beams [PDF]

open access: yes, 2012
In laser cutting of thick steel sheets, quality difference is observed between cut surfaces obtained with 1 micron and 10 micron laser beams. This paper investigates physical mechanisms for this interesting and important problem of the wavelength ...

Numerical and experimental investigation on pulsed nanosecond laser ablation processing of aluminum alloy

open access: yesJournal of Materials Research and Technology, 2022
The laser ablation of aluminum alloy 6061 was studied both experimentally and by computational modeling in this work. Six variations of the number of pulses of irradiation (1, 5, 10, 20, 50, and 100 pulses) combined with four different laser fluence (2.0
