Circuit boards from renewable raw materials
Research
Empa
Can ecologically sustainable circuit boards for the electronics industry be produced from cellulose fibers? Empa researcher Thomas Geiger looked into this question. He is now part of a multinational EU project called "Hypelignum". Its goal: biodegradable electronics.
A solar hydrogen system that co-generates heat and oxygen
TechTransfer
EPFL
EPFL researchers have built a pilot-scale solar reactor that produces usable heat and oxygen, in addition to generating hydrogen with unprecedented efficiency for its size.
Why we are taking a stand on the Swiss Climate Protection Law
Politics
ETH Zurich
Political debate is vital for a functioning democracy. And when it comes to complex issues such as climate change, scientists should be able to share their expertise and help shape opinion, says Reto Knutti.
Student-made sensor facilitates climate-conscious design of public squares
Research
ETH Zurich
ETH students have developed sensors that can indicate how people use urban spaces. They anonymously measure how people use objects such as chairs in a public square. The sensors have proven useful in the test run and could be used in future to plan public spaces based on needs.
Why are forests turning brown in summer?
Research
ETH Zurich WSL
Increasing summer heat and drought are affecting European forests – some years, trees brown prematurely and some even start to die back. Researchers from ETH Zurich and the WSL are showing how exceptional weather conditions over several years are turning forests brown.
Following the water cycle in the forest
Research
ETH Zurich
In the Forest Laboratory "Waldlabor" on Hönggerberg, ETH Zurich researchers investigate the storage and transport processes of water in the forest. Recently they showed that forest-floor litter and deadwood have a far larger influence on the forest water balance than expected.
