US Patent:

20180102200, Apr 12, 2018
Filed:

Oct 10, 2017
Appl. No.:

15/729078
Inventors:

- West Lafayette IN, US
Benxin Wu - West Lafayette IN, US
Assignee:

Purdue Research Foundation - West Lafayette IN
International Classification:

H01B 5/14
B05D 3/14
B05D 1/26
Abstract:

The present disclosure relates to a novel method of laser-based fabrication of a carbon nanotube (CNT)-metal composite on a flexible substrate, and the fabricated CNT-metal composite that is bonded with the flexible substrate, and that has a high electrical conductivity, and that has a longer bending-fatigue life than the laser-sintered metal of the same type without CNTs onto the flexible substrate.

US Patent:

20160016855, Jan 21, 2016
Filed:

Jun 12, 2015
Appl. No.:

14/738130
Inventors:

Benxin WU - West Lafayette IN, US
Jihua GOU - Orlando FL, US
International Classification:

C04B 35/56
Abstract:

Methods for making a carbon nanotube (CNT)-nonoxide structural ceramic nanocomposite as well as for enhancing at least one mechanical property or characteristic of a nonoxide structural ceramic material are provided. A mixture of CNT and nonoxide structural ceramic powder can be laser sintered to form desired carbon nanotube-nonoxide structural ceramic nanocomposites.

US Patent:

20150014289, Jan 15, 2015
Filed:

Jul 11, 2014
Appl. No.:

14/329327
Inventors:

Benxin Wu - Naperville IL, US
Yun Zhou - Fremont CA, US
Yibo Gao - Shanghai, CN
International Classification:

B23K 10/00
B23K 26/00
US Classification:

21912185, 2191216
Abstract:

Processes and corresponding or associated arrangements for removal of a burr from a workpiece, particularly micromachined workpieces, involving irradiating a plasma plume source material with a laser beam to generate a plasma plume. The plasma plume at least in part impacts the burr disposed on the workpiece to at least in part remove the burr from the workpiece. In select embodiments, the plasma plume source material can be a part of the workpiece or a non-workpiece sacrificial material.

US Patent:

20140263213, Sep 18, 2014
Filed:

Mar 14, 2014
Appl. No.:

14/212876
Inventors:

Benxin Wu - Naperville IL, US
International Classification:

B23K 26/00
B24B 1/04
US Classification:

21912169, 21912168, 451165, 451 36
Abstract:

Systems and processes for improved laser machining, such as micro machining, of a workpiece. Systems and processes involve directing at a first surface of the workpiece a laser beam and wherein at least the laser-irradiated region of the first surface of the workpiece is immersed in a liquid, and delivering to the liquid-immersed and laser-irradiated workpiece surface region at least a first ultrasound output from a first ultrasound device. The ultrasound output and the laser beam desirably impact the workpiece first surface substantially simultaneously.
