Effect of Heat Sink and Cooling Mediums on Ferrite Austenite Ratio and Distortion in Laser Welding of Duplex Stainless Steel 2205

open access: yesChinese Journal of Mechanical Engineering, 2019
In order to control the ferrite and austenite percentage in duplex stainless steel welding, many researchers try to change the laser welding parameters and cooling medium, but ignore to study the influence of heat sink effect on weld strength.

A Single Laser System for Ground-State Cooling of 25-Mg+

open access: yes, 2011
We present a single solid-state laser system to cool, coherently manipulate and detect $^{25}$Mg$^+$ ions. Coherent manipulation is accomplished by coupling two hyperfine ground state levels using a pair of far-detuned Raman laser beams.

Numerical Simulation of the Temperature Distribution and Solid-Phase Evolution in the LENS™ Process [PDF]

open access: yes, 2006
A three-dimensional finite element model was developed and applied to analyze the temperature and phase evolution in deposited stainless steel 410 (SS410) during the Laser Engineered Net Shaping (LENSTM) rapid fabrication process.

Combining antibody conjugates with cytotoxic and immune‐stimulating payloads maximizes anti‐cancer activity

open access: yesMolecular Oncology, EarlyView.
Methods to improve antibody–drug conjugate (ADC) treatment durability in cancer therapy are needed. We utilized ADCs and immune‐stimulating antibody conjugates (ISACs), which are made from two non‐competitive antibodies, to enhance the entry of toxic payloads into cancer cells and deliver immunostimulatory agents into immune cells.

Analysis of the Strength and toughness of welded joints in ultra high strength steel with a step-cooling laser welding

open access: yesHanjie xuebao
To address the strength-toughness mismatch in ultra-high strength steel welded joints, a step-cooling process inspired by the Quenching and Partitioning (Q&P) principle was proposed and its impact on the mechanical properties of welded joints was ...

Optimizing Laser Sintering Parameters and Cooling Channel Designs for Enhanced Injection Molding of Medical Tube Connectors

open access: yesJournal of Applied Science and Engineering
Respiratory equipment disconnections in hospitals pose severe risks, including hypoxia and mortality. Suboptimal tube connector quality, often worsened by traditional cooling mold designs, results in uneven thermal equilibrium, product deformation, and ...

RIPK4 function interferes with melanoma cell adhesion and metastasis

open access: yesMolecular Oncology, EarlyView.
RIPK4 promotes melanoma growth and spread. RIPK4 levels increase as skin lesions progress to melanoma. CRISPR/Cas9‐mediated deletion of RIPK4 causes melanoma cells to form less compact spheroids, reduces their migratory and invasive abilities and limits tumour growth and dissemination in mouse models.

Injection locking of a low cost high power laser diode at 461 nm [PDF]

open access: yes, 2016
Stable laser sources at 461 nm are important for optical cooling of strontium atoms. In most existing experiments this wavelength is obtained by frequency doubling infrared lasers, since blue laser diodes either have low power or large emission ...
