Come and listen to Chalmers research students presenting their latest research work for you. You don’t need previous knowledge about the students’ research topic and will get a glimps of the latest. 

The popular science presentation is a mandatory element in the doctoral education at Chalmers. You will take part of the newest scientific results and ideas and the researcher will present the work for a public environment in a language that anyone can understand. This will make this new research visible in an accessible way to a broad audience. 

Hårdmetall – från användning som metallbearbetningsverktyg till atomskaliga beräkningar
– Martin Gren
Hårdmetall är ett sammansatt material som huvudsakligen består av volframkarbid och kobolt. De enskilda komponenternas egenskaper kombineras för att ge ett material med en unik kombination av hårdhet och seghet vilket gör det perfekt för användning som verktygsmaterial inom olika former av metallbearbetning så som: svarvning och borrning. Materialets egenskaper beror till stor del på dess mikrostruktur, där både volframkarbidkorn och koboltkorn bildar varsitt kontinuerligt nätverk. I detta nätverk finns det därför massor av mellanytor mellan de enskilda materialen och mellan båda materialen. Egenskaperna för dessa mellanytor är viktiga parametrar för hur mikrostrukturen ser ut i det färdiga materialet. Min roll som forskare är att förstå och förutspå egenskaperna för dessa mellanytor, och det gör jag genom att skapa modellsystem för mellanytorna och tillämpa atomskaliga beräkningar.

Redefining the Metric System with Graphene – Hans He
The search for next generation of materials have lead scientists to study atomically thin 2D-materials. Graphene,which consists of a single atomic layer of carbon, is one popular candidate often lauded as a wonder material with endless potential. Graphene is currently mostly seen only in research laboratories, but one of the few real applications where it excels is in metrology. Metrology deals with our common understanding of units such as time, length or weight, and ensures that 1 kg is 1 kg everywhere. Interestingly, graphene plays a role in the new definition of the metric system and in this talk we will explore the potential of graphene to change the way we view, or more precisely weigh, the world.

Harnessing Heat: how nanophotonics can utilize thermal losses – Steven Jones
Heat is an unavoidable by-product of all physical processes. It results from the fact that no process is 100% efficient. Nanophotonics is no different. In nanophotonics we typically use tiny metallic antennae to probe the nanoscopic world. Historically scientists have endeavored to minimize or compensate for these thermal losses. Over the past few years however, we are now discovering that the heat produced in nanoscale light-matter interactions can open up exciting new ways to sense and manipulate the microscopic world.

Ocean observation from space – Anis Elyouncha
The ocean, covering more than 70 percent of our planet, is essential to life on Earth. It is a source of food and energy but also a source of hazards and it affects the weather and climate. Thus continuous monitoring of ocean’s health is of paramount importance.  The ocean is vast hence local measurements, using ships and buoys, are sparse and costly. Satellites are very useful tools for ocean observation covering large areas continuously. They provide information about sea level, sea ice concentration, ocean currents, sea surface temperature, sea surface salinity, ocean colour, ocean wind, wave parameters, etc. This information contributes to the understanding of ocean dynamics and environmental changes in the ocean. This presentation will give an overview of the relatively new discipline called “satellite oceanography” and describe in a simple way how satellites are used to measure physical parameters related to the ocean.
