The thesis describes experimental steps towards reduction of friction on the macroscopic scale by scenarios of thermo- and superlubricity well-known on the nanoscale.

Pratik is currently a student at Leiden University.

The demolition of the high-rise building is ready. The remaining debris are removed and the area is cleared. For the demolition, the University applied the BREEAM evaluation method at the level of ‘Excellent’, which means that the demolition operations were carbon neutral and did not cause any form…

Development of scenarios for 2050 detailed in an IO framework

What are the key issues in conducting LCA of bioenergy systems? What is the environmental sustainability status of second generation bioethanol? How much would the final results of biogenic carbon neutrality assumptions deviate from the true values based on a complete inventory? How to assess the impact…

Since the adoption of agriculture people have cultivated fields. The project concerns all kinds of aspects related to raising crops.

Xiamen is a a city in the Chinese province Fujian. It currently has about 4.3 million citizens in the city. It is therefore the largest city of the province.

Research at the MCBIM group is comprised of the following research themes:

What are the functions of autophagy in the filamentous fungus Aspergillus niger?

Lecture

Vibrating carbon monoxide molecules adsorbed at the surface of a salt crystal stop moving after a few milliseconds. Scientists now discovered this is dominantly due to the emission of electromagnetic waves. The role of the chemical bond at the surface thereby appears to be less important than previously…

Patterns of paleomobility in the Caribbean were studied through an inter-disciplinary approach using a combination of archaeological, osteological, mortuary, and isotopic data.

The Supramolecular & Biomaterials Chemistry group of Prof. dr. Alexander Kros is active in the field of self-assembly of amphiphilic peptides and applying them in supramolecular chemistry.

This thesis revolves around the electronic spectroscopy of molecules in the laboratory and the search for the carriers of the diffuse interstellar bands (DIBs).

Acidobacteria is a widely distributed phylum but their functional roles in ecosystem processes are still largely elusive.

How to contribute to a quantum leap of eco-industrial symbiosis in China?

Natural resources are becoming increasingly scarce. If we want to maintain our current standard of living, we will need inventive solutions. The researchers at the Institute of Environmental Sciences (CML) share their thoughts on how to achieve a fully circular economy in which as little use as possible…

Radiation can be used to determine the isotope ratio of a skeleton. This provides information about where our ancestors lived and what they consumed. Dr Andrea Waters has developed a revolutionary method that can trace patterns of consumption from tens of thousands of years ago.

This functional genomics project aims at understanding the biology of the underlying mycelium differentiation and autolysis processes in much more detail.

A major goal of ABS research is to overcome one of the major bottle-necks in metabolomic research: the lack of a high-throughput infrastructure in which thousands of samples can be processed in a standardized and cost-effective way (max. a few tens of Euro’s per sample for a full metabolome profile).…

To limit the effects of climate change, global average temperature since pre-industrial measurements are to be kept well below 2 °C preferably even at 1.5 °C.

The focus throughout this thesis will be on gathering fundamental studies of the detailed structure and composition of the electrode/electrolyte interface effect on the rate and mechanism of key electrocatalytic reactions.

The emissions of the Chinese industrial sector alone comprise 24.1% of global emissions (7.8 GtCyr−1 in 2015). This makes Chinese industrial emissions of unique national and international relevance in climate policy. This study reports a literature survey that quantitatively describes the evolution…

With the energy transition toward a renewable energy supply and a CO2-neutral economy, electrification of the energy system is rising in importance, which leads to the challenge of long-term storage of renewable electricity.

An important feature of atopic eczema (AE) is a decreased skin barrier function. The stratum corneum (SC) lipids - comprised of ceramides (CERs), free fatty acids (FFAs) and cholesterol - fulfill a predominant role in the skin barrier function.

TRANSVAC is a collaborative infrastructure project funded by the European Commission (EC), initially under the 7th Framework Programme (FP7) and currently under Horizon 2020. The project is a joint effort of leading European groups working in the field of vaccine development, and is coordinated by…

Leiden University works on sustainabilty in three particular areas: business operations, teaching and research. We also communicate on this issue with students, staff and external partners to explain what we are doing and to promote awareness of sustainability.
