Laser-driven proton acceleration with nanostructured targets [PDF]

open access: yes, 2017
Laser-driven particle acceleration has become a growing field of research, in particular for its numerous interesting applications. One of the most common proton acceleration mechanism that is obtained on typically available multi-hundred TW laser ...

Effect of fiber-oriented direction on mechanical and ablative performance of C/C-HfC-ZrC-SiC composites

open access: yesJournal of Asian Ceramic Societies, 2020
C/C-HfC-ZrC-SiC composites are fabricated by precursor infiltration and pyrolysis process by using SiC, ZrC, and HfC precursors. With incorporation of ZrC-SiC ceramics, the ablation rates of the C/C-HfC-ZrC-SiC composites are one order magnitude lower ...

Metabolic crosstalk: molecular links between glycogen and lipid metabolism in obesity. [PDF]

open access: yes, 2014
Glycogen and lipids are major storage forms of energy that are tightly regulated by hormones and metabolic signals. We demonstrate that feeding mice a high-fat diet (HFD) increases hepatic glycogen due to increased expression of the glycogenic ...

Influence of Ablation on Differential Arc Resistance

open access: yesPLASMA PHYSICS AND TECHNOLOGY, 2017
The influence of ablation on the du/di behavior of an arc in a model gas circuit breaker was examined. Specifically the transition from a state without ablation in the nozzle towards states with ablation was of interest, since prior work indicated that for high currents the voltage becomes constant or du/di gets even positive if ablation is present ...

Picosecond Laser Ablation of Polyhydroxyalkanoates (PHAs): Comparative Study of Neat and Blended Material Response [PDF]

open access: yes, 2019
Polyhydroxyalkanoates (PHAs) have emerged as a promising biodegradable and biocompatible material for scaffold manufacturing in the tissue engineering field and food packaging. Surface modification is usually required to improve cell biocompatibility and/

Nd:YAG Laser Ablation and Acid Resistance of Enamel

open access: yesDental Materials Journal, 2003
The acid resistance of Nd:YAG laser-ablated enamel surfaces was studied by evaluating crystal structure, mineral distribution, and fluorescence radiance and image in the present study. For comparison, 37% phosphoric acid etching was performed. The formation of beta-tricalcium phosphate (beta-TCP) was confirmed in the laser-ablated surface.

Four-point resistance of individual single-wall carbon nanotubes [PDF]

open access: yes, 2005
We have studied the resistance of single-wall carbon nanotubes measured in a four-point configuration with noninvasive voltage electrodes. The voltage drop is detected using multiwalled carbon nanotubes while the current is injected through ...

Growth control of oxygen stoichiometry in homoepitaxial SrTiO3 films by pulsed laser epitaxy in high vacuum [PDF]

open access: yes, 2016
In many transition metal oxides (TMOs), oxygen stoichiometry is one of the most critical parameters that plays a key role in determining the structural, physical, optical, and electrochemical properties of the material. However, controlling the growth to

Novel HfxTa1−xC solid solution nanowire toughened HfC coating: An effective strategy for synchronous enhanced mechanical and anti-ablation performance

open access: yesJournal of Advanced Ceramics
Ultra-high-temperature ceramic nanowires have shown increasing potential for use as thermal structural components. Herein, novel single-crystal Hf0.5Ta0.5C solid solution nanowires were synthesized and incorporated with a HfC coating to construct a ...
