In this work radiative properties of neutral elements with one or two electrons outside closed subshells have been investigated. Using laser techniques in connection with atomic beams selective excitation of Rydberg states was performed. Most of the studied states were populated with two-step excitation. Some states were reached directly from the ground state or from a metastable state and occasio

Reaction of Ru3(CO)12 with tris(2-thienyl)phosphine (PTh3) in CH2Cl2 at room temperature or in THF in the presence of a catalytic amount of Na[Ph2CO] furnishes the carbonyl substitution products Ru3(CO)11(PTh3) (1), Ru3(CO)10(PTh3)2 (2), and Ru3(CO)9(PTh3)3 (3). Heating 1 in toluene affords the cyclometalated cluster Ru3(CO)9{μ-Th2P(C4H2S)}(μ-H) (4) resulting from carbonyl loss and carbon-hydrogen

Flexibility of the energy system plays a vital role when integrating non-dispatchable renewable energy technologies. However, flexibility of the energy system has been often discussed only focusing on the operation of the energy system. This study extends the flexibility concept considering both design and operation of the energy system. In order to achieve this, pseudo chronological scenarios use

We present an efficient photon-echo experiment based on atomic frequency combs [Phys. Rev. A 79 (2009) 052329]. Echoes containing an energy of up to 35% of that of the input pulse are observed in a Pr3+ -doped Y2SiO5 crystal. This material allows for the precise spectral holeburning needed to make a sharp and highly absorbing comb structure. We compare our results with a simple theoretical model w

Talking about the revolution, it sounds like a whisper, but I think even Tracy feels it’s time to scream it from the rooftops; I am fed up of sitting in the bistro of this ever speeding train of consumption, racking up a tab that our coming generations will have to pay for with their future. I want to jump off and run in another direction towards a more beautiful existence. In my life everything h

A joint research between Lund University and Chalmers Competence Centre for Catalysis have shown promising results for a Rh-based catalyst for CO2 hydrogenation catalytic applications. The original catalyst consisted of a dispersion of nanoparticles onto a porous 3D oxide network. To gain a deeper understanding of the catalyst, a surface science study is necessary, but it is impossible to perform

We present results of the commissioning of a new injector for the Brazilian Synchrotron Light Source. The new injector consists of the existing 125-MeV LINAC and a new 500-MeV booster synchrotron. At present, about 40 mA can be injected into the booster and about 15 mA can be ramped up to 500 MeV at a repetition rate of 0.17 Hz. The new injector has allowed the accumulation of up to 540 mA in the

Carbon capture and storage (CCS) is considered by some to be a critical climate change mitigation technology, and a key element in efforts to limit the global temperature increases in line with the goals of the Paris Agreement. Implementation of CCS in mitigation scenarios assumes that it provides cost-effective emission reductions, and/or can achieve negative emissions when combined with bioenerg

Cleantech—technologies with a reduced environmental impact—has emerged as an important set of solutions for addressing pollution and its impacts in China. The goal of this study is to map out wherein Chinese actors with first-hand knowledge of cleantech investments think the largest domestic investment opportunities are found, understand the underlying reasons, and then evaluate how consistently t

The fuel cell performance of membrane electrode assemblies with a Pt anode and Pd, PdCu or Pd5Cu4Pt cathodes has been tested during 116 h (beginning of life). The incorporation of Cu to Pd increases the fuel cell performance. Incorporation of Pt leads to further improvement. SEM micrographs of the as-prepared and the fuel cell-tested assemblies show the effects of the 116 h of continuous operation

This study is the first to use a newly-developed material via hydrothermal method, cerium oxide nanowires doped with reduced graphene oxide (CNW-RGO) for reductive H2 production. The detailed characteristics of the CNW-RGO materials were investigated to explore the capabilities of reductive production. The mean diameter of the CNWs was uniform at 22 nm. Owing to RGO-doping, the energy gap between

16 April 2026 08:15 to 09:30 | Welcome to a breakfast seminar which sheds some light on the progress of the climate crisis: what key events have occurred in the last ten years, and what is in store for the future? Climate change, driven by greenhouse gas emissions from human activities, is gathering pace, and we are about to pass the 1.5 degree goal set by the world in Paris 2015. Climate change a

To allow further device scalability within the data storage industry there needs to be continued research of new technologies. One promising technology is the Magnetic Random Access Memory (MRAM), based on magnetoresistive elements, which is non-volatile; consume low power and have fast read and write operations. To make the technology scalable, the bit (the smallest element in the MRAM) needs to
