Circadian clocks optimize the timing of physiological processes in synchrony with daily recurring and therefore predictable changes in the environment. Until the late 1990s, circadian clocks were thought to exist only in the central nervous systems of animals; elegant studies in cultured fibroblasts and using genetically encoded reporters in Drosophila melanogaster and in mice showed that clocks a
The development of high-energy density solid-state batteries is critical for the achievement of carbon neutrality goals and the advancement of clean energy. Still, the fundamental understanding of lithium transport mechanisms and degradation processes remains limited. Current characterisation methods face significant challenges in studying these complex systems, particularly due to the difficulty
This article summarizes the contributions in this special issue on Diffraction-Limited Storage Rings. It analyses the progress in accelerator technology enabling a significant increase in brightness and coherent fraction of the X-ray light provided by storage rings. With MAX IV and Sirius there are two facilities under construction that already exploit these advantages. Several other projects are
This chapter aims to explore community energy (CE)—energy communities that are established and run by private citizens—in four Eastern European countries. The chapter first analyses general contextual conditions supporting the diffusion of CE initiatives in the Baltic Sea Region. Subsequently, it reports the findings of four case studies from Estonia, Latvia, Lithuania, and Poland illustrating som
Indonesia is a significant global player both in terms of economic performance and Carbon Dioxide (CO2) emissions. While its total Gross Domestic Product (GDP) and emissions are ranked high in global comparisons, both in terms of per capita measures have a relatively low ranking, suggesting that there is potentially more growth to come. Growth in Indonesia’s total emissions is being driven by econ
The aim of this master thesis is to conclude how the energy systems of smart cities can be designed to achieve an annual net-zero energy consumption. The study investigated different techniques that can be used for producing and storing energy locally. This was implemented on a planned residential project located in Veberöd, south of Scania. Hence, the heating and domestic hot water demand were ba
Long before the Bluetooth symbol started glowing blue ... ... and found its way into the pockets of people all over the world, there was a professor in Lund who refused to give up on a seemingly impossible idea: to replace the cable between mobile phones and headphones with a wireless link. And it was not just any link. It would work at a distance of ten metres, barely draw any power, take up hard

In this work, a three-dimensional TiO2-graphene composite with large specific surface area is designed by freeze drying. In this architecture, primary TiO2 nanoparticles (less than 10 nm in size) are wrapped with graphene homogeneously, forming spherical secondary particles (≈100 nm), and the spherical TiO2 particles further agglomerate into platelet-like particles with several micrometers in size
This paper presents a new analytical solution for the influence of regional groundwater flow on the performance of borehole heat exchangers. The solution concerns a vertical borehole. The transient thermal response for the fundamental case of a step-change in heat injection rate is given. The solution is remarkably simple and the formulas quite handy considering the complexity of the convective-di
Though commonly used to calculate Q-factor and fractional bandwidth, the energy stored by radiating systems (antennas) is a subtle and challenging concept that has perplexed researchers for over half a century. Here, the obstacles in defining and calculating stored energy in general electromagnetic systems are presented from first principles as well as using demonstrative examples from electrostat
