The cluster adsorption is found to be dominated by van der Waals forces. The electronic structure and in particular the excitation energies of the bare clusters and the TiO2/graphene composites are found to vary largely in dependence on the size of the respective constituents. This holds in particular for the energy and the spatial localization of the highest occupied and lowest unoccupied molecular orbitals. In addition to a substantial gap narrowing, a pronounced separation of photoexcited electrons and holes is predicted in some instances. This is expected to prolong the lifetime of photoexcited carriers. Altogether, TiO2/graphene composites are predicted to be promising photocatalysts with improved electronic and photocatalytic properties compared to bulk TiO2. article_type: original author: - first_name: Sabuhi full_name: Badalov, Sabuhi id: '78800' last_name: Badalov orcid: 0000-0002-8481-4161 - first_name: René full_name: Wilhelm, René last_name: Wilhelm - first_name: Wolf Gero full_name: Schmidt, Wolf Gero id: '468' last_name: Schmidt orcid: 0000-0002-2717-5076 citation: ama: Badalov S, Wilhelm R, Schmidt WG.

In inhomogeneous ensembles a macroscopic optical polarization decays rapidly due to dephasing, which, however, is reversible in photon echoes carrying complete information about the coherent ensemble dynamics. Control of the echo emission time is mandatory for applications. Here, we propose a concept to reach this goal. In a two-pulse photon echo sequence, we apply an additional resonant control pulse with multiple of 2π area. Depending on its arrival time, the control slows down dephasing or rephasing of the exciton ensemble during its action. We demonstrate for self-assembled (In,Ga)As quantum dots that the photon echo emission time can be retarded or advanced by up to 5 ps relative to its nominal appearance time without control. This versatile protocol may be used to obtain significantly longer temporal shifts for suitably tailored control pulses. article_number: '228' author: - first_name: Alexander N. full_name: Kosarev, Alexander N. last_name: Kosarev - first_name: Hendrik full_name: Rose, Hendrik id: '55958' last_name: Rose orcid: 0000-0002-3079-5428 - first_name: Sergey V. full_name: Poltavtsev, Sergey V. last_name: Poltavtsev - first_name: Matthias full_name: Reichelt, Matthias id: '138' last_name: Reichelt - first_name: Christian full_name: Schneider, Christian last_name: Schneider - first_name: Martin full_name: Kamp, Martin last_name: Kamp - first_name: Sven full_name: Höfling, Sven last_name: Höfling - first_name: Manfred full_name: Bayer, Manfred last_name: Bayer - first_name: Torsten full_name: Meier, Torsten id: '344' last_name: Meier orcid: 0000-0001-8864-2072 - first_name: Ilya A. full_name: Akimov, Ilya A. last_name: Akimov citation: ama: Kosarev AN, Rose H, Poltavtsev SV, et al.

With their additional degree of freedom, the vorticity, they have been widely investigated in many physical systems and different materials for fundamental interest and for applications in data storage and information processing. Vortices have also been observed in non-equilibrium exciton-polariton condensates in planar semiconductor microcavities. There they appear spontaneously or can be created and pinned in space using ring-shaped optical excitation profiles. However, using the vortex state for information processing not only requires creation of a vortex but also efficient control over the vortex after its creation. Here we demonstrate a simple approach to control and switch a localized polariton vortex between opposite states. In our scheme, both the optical control of vorticity and its detection through the orbital angular momentum of the emitted light are implemented in a robust and practical manner. author: - first_name: Torsten full_name: Meier, Torsten id: '344' last_name: Meier orcid: 0000-0001-8864-2072 - first_name: Xuekai full_name: Ma, Xuekai last_name: Ma - first_name: Bernd full_name: Berger, Bernd last_name: Berger - first_name: Marc full_name: Aßmann, Marc last_name: Aßmann - first_name: Rodislav full_name: Driben, Rodislav last_name: Driben - first_name: Christian full_name: Schneider, Christian last_name: Schneider - first_name: Sven full_name: Höfling, Sven last_name: Höfling - first_name: Stefan full_name: Schumacher, Stefan id: '27271' last_name: Schumacher orcid: 0000-0003-4042-4951 citation: ama: Meier T, Ma X, Berger B, et al.

In addition to the daily energy consumption, this international standard- ization introduced performance tests for cooling capacity and temperature rise time. While the cooling capacity has long been anchored in various test procedures of consumer organizations, the temperature rise time, which has only been tested on freezers so far, will be a decisive factor in the future. Moreover, the need for so-called "smart appliances" that may balance power consumption is increasing since such devices may compensate the volatility of renewable energies and thus stabilize the power grid. Against this background, eight commercial household refrigerators and refrigerator-freezers are equipped with polymer-bound phase change materials (PCM) and their performance is determined under the new stan- dard test conditions. The results show that the introduction of PCM increases the cooling capacity by up to 33 % and also increases the temperature rise time by up to 145 %, without affecting power consump- tion, as compared to the unmodified refrigeration appliances. author: - first_name: Gerrit full_name: Sonnenrein, Gerrit last_name: Sonnenrein - first_name: Elmar full_name: Baumhögger, Elmar id: '15164' last_name: Baumhögger - first_name: Andreas full_name: Elsner, Andreas id: '16124' last_name: Elsner - first_name: A. full_name: Morbach, A. last_name: Morbach - first_name: Moritz full_name: Neukötter, Moritz id: '45530' last_name: Neukötter orcid: 0000-0001-9101-8828 - first_name: Andreas full_name: Paul, Andreas id: '7828' last_name: Paul - first_name: J. full_name: Vrabec, J. last_name: Vrabec citation: ama: Sonnenrein G, Baumhögger E, Elsner A, et al.

Past studies provide basic evidence for increasing electricity consumption of cooling appliances with ageing but fail to investigate the associated technical wear. Concentrating on the degradation of the thermal insulation, we first determined the ageing process of sealed samples of polyurethane rigid foam by investigating changes in cell gas composition and thermal conductivity over time. Simultaneously, the main challenge was to develop an approach that investigates the age-related efficiency loss of the insulation without its destruction. This testing procedure is referred to as the Bonn method. The non-destructive Bonn method was applied to varying refrigerator models in a series of successive experiments to evaluate the insulation degradation over time. Subsequently, the physical relationship between the test value of the Bonn method and the heat transfer through the multi-layered compartment walls of domestic refrigeration appliances was established, ultimately characterising the degrading insulation in terms of increasing heat transfer. Our results give substantiated evidence that the efficiency loss of cooling appliances is greatly influenced by insulation degradation over time. The ageing of sealed samples of polyurethane rigid foam indicates a large initial increase of thermal conductivity by 15% within the first year, corresponding to a change in cell gas composition. These results are in line with those of the Bonn method, emphasising an increasing heat flow through the multi-layered compartment walls of domestic refrigerators with ageing. Therewith, the present study is of significance to a wide range of stakeholders and forms the basis for future research. article_number: '115113' author: - first_name: Christian full_name: Hueppe, Christian last_name: Hueppe - first_name: Jasmin full_name: Geppert, Jasmin last_name: Geppert - first_name: Rainer full_name: Stamminger, Rainer last_name: Stamminger - first_name: Hendrik full_name: Wagner, Hendrik last_name: Wagner - first_name: Heike full_name: Hoelscher, Heike last_name: Hoelscher - first_name: Jadran full_name: Vrabec, Jadran last_name: Vrabec - first_name: Andreas full_name: Paul, Andreas id: '7828' last_name: Paul - first_name: Andreas full_name: Elsner, Andreas id: '16124' last_name: Elsner - first_name: Wolfgang full_name: Becker, Wolfgang last_name: Becker - first_name: Ulrich full_name: Gries, Ulrich last_name: Gries - first_name: Alfred full_name: Freiberger, Alfred last_name: Freiberger citation: ama: 'Hueppe C, Geppert J, Stamminger R, et al.

These techniques allow for the joining of dissimilar materials and thus enable multi-material design, while thermic joining methods reach their limits. Semi-tubular self-piercing riveting is an important mechanical joining technology. The rivet production, however, is costly and time-consuming, as the process consists of several process steps including the heat treatment and coating of the rivets in order to achieve an adequate strength and corrosion resistance. The use of high nitrogen steel as rivet material leads to the possibility of reducing process steps and hence increasing the efficiency of the process. However, the high tool loads being expected due to the high strain hardening of the material are a major challenge during the rivet production. Thus, there is a need for appropriate forming strategies, such as the manufacturing of the rivets at elevated temperatures. Prior investigations led to the conclusion that forming already at 200 °C results in a distinct reduction of the yield strength. To create a deeper understanding of the forming behaviour of high nitrogen steel at elevated temperatures, compression tests were conducted in a temperature range between room temperature and 200 °C. The determined true stress – true strain curves are the basis for the further process and tool design of the rivet production. Another key factor for the rivet manufacturing at elevated temperatures is the influence of the process temperature on the tribological conditions. For this reason, ring compression tests at room temperature and 200 °C are carried out. The friction factors are determined on the basis of calibration curves resulting from the numerical analysis of the ring compression process. The investigations indicate that the friction factor at 200 °C is significantly higher compared to room temperature. This essential fact has to be taken into account for the process and tool design for the rivet production using high nitrogen steel. article_number: '100023' citation: ama: Kuball C-M, Jung R, Uhe B, Meschut G, Merklein M, eds.

Self-piercing riveting is an established technique for joining these materials. The dissimilar properties of the two materials have led to a number of different rivet geometries in the past. Each rivet geometry fulfils the requirements of the materials within a limited range. In the present investigation, an improved rivet geometry is developed, which permits the reliable joining of two material combinations that could only be joined by two different rivet geometries up until now. Material combination 1 consists of high-strength steel on both sides, while material combination 2 comprises aluminium on the punch side and high-strength steel on the die side. The material flow and the stress and strain conditions prevailing during the joining process are analysed by means of numerical simulation. The rivet geometry is then improved step-by-step on the basis of this analysis. Finally, the improved rivet geometry is manufactured and the findings of the investigation are verified in experimental joining tests. article_type: original author: - first_name: Benedikt full_name: Uhe, Benedikt id: '38131' last_name: Uhe - first_name: Clara-Maria full_name: Kuball, Clara-Maria last_name: Kuball - first_name: Marion full_name: Merklein, Marion last_name: Merklein - first_name: Gerson full_name: Meschut, Gerson id: '32056' last_name: Meschut orcid: 0000-0002-2763-1246 citation: ama: Uhe B, Kuball C-M, Merklein M, Meschut G.
