Cooling potential of galinstan-based minichannel heat sinks
13th InterSociety Conference on Thermal and Thermomechanical Phenomena in Electronic Systems, 2012Galinstan, a gallium, indium and tin eutectic, may be exploited for enhanced cooling of microelectronics due to its unique thermophysical properties. However, a critical evaluation of the cooling potential of galinstan has not been undertaken. Provided here is a first-order optimization model to minimize the total thermal resistance of galinstan-based ...

Galinstan Liquid Metal Electrical Contacts for Monolayer-Modified Silicon Surfaces
Langmuir, 2023Galinstan is the brand name for a low-melting gallium-based alloy, which is a promising nontoxic alternative to mercury, the only elemental metal found in the liquid state at room temperature. Liquid alloys such as Galinstan have found applications as electromechanical actuators, sensors, and soft contacts for molecular electronics.

A galinstan expansion femtosyringe for microinjection of eukaryotic organelles and prokaryotes
Nature Biotechnology, 1999A galinstan expansion femtosyringe enables femtoliter to attoliter samples to be introduced into prokaryotes and subcellular compartments of eukaryotes. The method uses heat-induced expansion of galinstan (a liquid metal alloy of gallium, indium, and tin) within a glass syringe to expel samples through a tip diameter of about 0.1 microm. The narrow tip

Photovoltaic Modules Using a Galinstan Paste Interconnection
Journal of the Korean Physical Society, 2019A shingled silicon photovoltaic (PV) module without busbars on the front side of a solar cell can increase the light-receiving area and provide more power than a conventional PV module. However, there are several issues, such as damage by laser cutting and interconnection by conductive paste.

On the Potential of Galinstan-Based Minichannel and Minigap Cooling
IEEE Transactions on Components, Packaging and Manufacturing Technology, 2014Galinstan, a gallium, indium, and tin eutectic, may be exploited for enhanced cooling of microelectronics because of its favorable thermophysical properties. A careful evaluation of its cooling potential, however, has not been undertaken. Provided here is a first-order model to compute the total (i.e., caloric plus conjugate conduction and convection ...

Note: Electrode polarization of Galinstan electrodes for liquid impedance spectroscopy
Review of Scientific Instruments, 2011Electrode polarization is a significant obstacle in the impedance measurements of ionic liquids. An atomically smooth electrode surface could potentially reduce unwanted impedance contributions from electrode polarization. Liquid metal electrodes were formed by adhering Galinstan to acrylic plates in a parallel-plate capacitor arrangement.

Langmuir, 2022
When exposed to air, gallium-based alloys rapidly form a thin oxide layer with viscoelasticity and high adhesion. Although previous work demonstrated that an oxide layer inhibits liquid metal droplet rebound, there is still a lack of a quantitative study to elaborate how an oxide layer affects the impact dynamics.

PDMS based coplanar microfluidic channels for the surface reduction of oxidized Galinstan
Lab Chip, 2014Galinstan has the potential to replace mercury - one of the most popular liquid metals. However, the easy oxidation of Galinstan restricts wide applicability of the material. In this paper, we report an effective reduction method for the oxidized Galinstan using gas permeable PDMS (polydimethlysiloxane)-based microfluidic channel. The complete study is

An Integrated Liquid Cooling System Based on Galinstan Liquid Metal Droplets
ACS Applied Materials & Interfaces, 2016The continued miniaturization of electronic components demands integrated liquid cooling systems with minimized external connections and fabrication costs that can be implanted very close to localized hot spots. This might be challenging for existing liquid cooling systems because most of them rely on external pumps, connecting tubes, and ...

A coplanar microfluidic channel applied for surface modification of oxidized Galinstan
2013 13th IEEE International Conference on Nanotechnology (IEEE-NANO 2013), 2013In this paper, a gas permeable PDMS (polydimethlysiloxane) based microfluidic device has been reported for surface modification of oxidized Galinstan. A microchannel with Galinstan droplets was surrounded by another coplanar channel filled with HCl solution. Due to the excellent permeability of PDMS, the HCl vapor easily passed through a thin PDMS wall
