A Refined Model for Ablation Through Cavitation Bubbles with Ultrashort Pulse Lasers

open access: yesPhotonics
(1) Background: Ultrashort high-energy laser pulses may cause interaction mechanisms, including photodisruption and plasma-induced ablation in the medium.

Theoretical fundamentals of short pulse laser–metal interaction: A review

open access: yesNanotechnology and Precision Engineering, 2020
Short and ultrashort pulse lasers offer excellent advantages in laser precision machining mainly because of their high pulse energy and low ablation threshold.

Translophagy—A potential link between autophagy impairment and translational errors

open access: yesFEBS Letters, EarlyView.
Neurodegenerative diseases are characterised by the accumulation of abnormal proteins and protein aggregates, but their origin often remains unknown. We propose that selective autophagy removes damaged protein‐making machinery, preventing errors during protein synthesis.

In vivo ultrasound thermal ablation control using echo decorrelation imaging in rabbit liver and VX2 tumor.

open access: yesPLoS ONE, 2019
The utility of echo decorrelation imaging feedback for real-time control of in vivo ultrasound thermal ablation was assessed in rabbit liver with VX2 tumor. High-intensity focused ultrasound (HIFU) and unfocused (bulk) ablation were performed using 5 MHz

‘Guide and Prejudice’— How Argonautes recognize targets across domains of life

open access: yesFEBS Letters, EarlyView.
Argonaute proteins use short nucleic‐acid guides to locate and regulate specific targets across all domains of life. Despite striking diversity—from human gene silencing to bacterial immune defence—all Argonautes share a conserved three‐stage recognition logic: guide‐directed sampling, progressive target pairing with a conformational checkpoint and ...

Femtosecond laser ablation of nitrocellulose for spatio-temporal flow control in µPADs

open access: yesFrontiers in Physics
Microfluidic paper-based analytical devices (μPADs) are gaining popularity due to their low cost and ease of use, but controlling fluid flow for more complex biochemical assays within these devices remains challenging. This study investigates femtosecond

New progress in tumor treatment based on nanoparticles combined with irreversible electroporation

open access: yesNano Select, 2022
Nanoknife is a new tumor ablation technology. It forms nano permanent perforation on tumor cells by releasing high‐voltage pulses, destroying the intracellular balance and making cells apoptosis rapidly.

Metastasis on pause: How dormant tumor cells stay hidden within the tumor microenvironment and evade immune surveillance

open access: yesMolecular Oncology, EarlyView.
Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...

Ultrashort pulse laser ablation of dielectrics: Thresholds, mechanisms, role of breakdown [PDF]

open access: yesScientific Reports, 2016
AbstractIn this paper, we establish connections between the thresholds and mechanisms of the damage and white-light generation upon femtosecond laser irradiation of wide-bandgap transparent materials. On the example of Corning Willow glass, evolution of ablation craters, their quality, and white-light emission were studied experimentally for 130-fs ...

Debris cover and surface melt at a temperate maritime alpine glacier: Franz Josef Glacier, New Zealand [PDF]

open access: yes, 2012
Melt rates on glaciers are strongly influenced by the presence of supraglacial debris, which can either enhance or reduce ablation relative to bare ice.
