How to Make a Science Video Workshop

Success Stories, , ,

In November we carried out a DIY science video workshop in Turku (Finland), where participants learned about the basics of making videos for promoting their business, research, work group or other things. Furthermore we also discussed how to properly set up the related media channels and videos and how to properly distribute the video to reach a larger audience and generate a constant stream of viewers. As a practical example we showed how Captain Corrosion OÜ and the Laboratory of Thin Film Technology (Institute of Physics, University of Tartu, Estonia) have collaborated to produce engaging science videos that have been watched hundreds of thousands times over the last few years.

Special thanks to the Turku Science Park, PoRes Communication and Tartu Science Park for making the event possible!

Corrosion Testing of Materials and Coatings

Success Stories, ,

Captain Corrosion recently tested the corrosion resistance of various metals and protective coatings for a client. We tested 8 different samples in 5 different environments in total and the goal was to get an overview which materials and coatings our client needs to use for specific applications. As can be seen from the table below, some coatings needed maintenance after 1000h corrosion test while others remained completely unharmed.

Science Video Series About Corrosion in Space

Success Stories, , ,

Captain Corrosion OÜ proudly presents a three part video series about corrosion in space. These science videos were made in collaboration with the department of materials science, University Tartu and were partially funded by the “Center of Excellence” (Project TK141). Corrosion in space is actually quite relevant right now as there are more spacecrafts in the orbit than ever before and their number keeps increasing. An average spy satellite, disguised as a weather satellite, costs about 400 million euros and their lifespan is somewhat limited due to various reasons like human errors, software/hardware failure and degradation of specific spacecraft parts due to the hostile environment of space (corrosion!). This “corrosion” of materials in space however can be quite complicated as there are multiple factors that contribute to the process. In our video series we discuss some of the most important factors. The general idea of this series is to provide additional information for companies that make spacecraft component so they can better plan their devices to last as long as possible in space.

Part 1 – How Does Atomic Oxygen Cause Corrosion in Space?

Part 2 – How do Charged Particles Cause Corrosion in Space?

Part 3 – How does Radiation Cause Corrosion in Space?

Animation of Pulsed Laser Deposition for the Group of Sensor Technologies

Success Stories, , , ,

This video was made by Captain Corrosion OÜ for the Group of Sensor Technologies (Institute of Physics, University of Tartu) to show the working principle of pulsed laser deposition (PLD), where a pulsing laser beam extracts matter from the target. This extracted matter is then deposited to the substrate. By tuning the level of vacuum in the deposition chamber and the intensity of the laser it is possible to use PLD technology to introduce different modifications into graphene. The Group of Sensor Technologies uses this method to create novel graphene-based gas sensors that can be used for instance for measuring the level of pollution in air.

Scanning Electron Microscopy (SEM) Studies for Biometric OÜ

Success Stories, , , , , , , ,

 

The company asked us to do elemental analysis for multiple dental implant components in order to confirm the quality of the metals. Due to the difficult three-dimensional shape of the substrates, the studies were carried out using a high resolution scanning electron microscope “Helios NanoLab 600” (FEI), equipped with an energy-dispersive X-ray spectrometry (EDX) analyzer INCA Energy 350 (Oxford Instruments). The samples were attached to the mushroom-shaped holders with a carbon tape. The studies showed that the metals used by Biometric OÜ are indeed high quality medical titanium. We also made high resolution images of the implants surface, which has been developed to be biocompatible, support osseointegration and have a good adhesion with the surrounding tissue.
