Access to metastable complex ion conductors via mechanosynthesis: Preparation, microstructure and conductivity of (Ba,Sr)LiF3 with inverse perovskite structure

Düvel, A.; Wegner, S.; Efimov, K.; Feldhoff, A.; Heitjans, Paul; Wilkening, Martin (Cambridge : Royal Society of Chemistry, 2011)

Highly metastable Ba1−xSrxLiF3 (0 < x ≤ xmax ≈ 0.4) with an inverse perovskite structure analogous to that of BaLiF3 was synthesized by soft mechanical treatment of BaF2 and LiF together with SrF2 at ambient temperature. ...
Dielectric properties of PVDF based thin films and electrospun mats

Tretiakov, A.; Kapralova, V.; Sudar, N.; Gryshkov, O.; Glasmacher, B. (Bristol : Institute of Physics Publishing, 2019)

Dielectric properties of polyvinylidene fluoride based thin films and electrospun mats have been studied. Frequency dependences of samples capacity and tangent of dielectric losses have been obtained. The influence of ...
High repetition rate, J-level, CPA-free ultrashort pulse multipass amplifier based on Ho:YLF

Hinkelmann, Moritz; Wandt, Dieter; Morgner, Uwe; Neumann, Jörg; Kracht, Dietmar (Washington, DC : Optical Society of America, 2018)

We report on CPA-free multipass amplification of ps-pulses in Holmium-doped yttrium lithium fluoride (Ho:YLF) crystals up to µJ pulse-energy-covering repetition rates from 10 kHz up to 500 kHz. The seed pulses at a wavelength ...
Investigating the strain, temperature and humidity sensitivity of a multimode graded-index perfluorinated polymer optical fiber with bragg grating

Zheng, Yulong; Bremer, Kort; Roth, Bernhard (Basel : MDPI AG, 2018)

In this work we investigate the strain, temperature and humidity sensitivity of a Fiber Bragg Grating (FBG) inscribed in a near infrared low-loss multimode perfluorinated polymer optical fiber based on cyclic transparent ...
Long-period gratings in highly germanium-doped, single-mode optical fibers for sensing applications

Schlangen, Sebastian; Bremer, Kort; Zheng, Yulong; Böhm, Sebastian; Steinke, Michael; Wellmann, Felix; Neumann, Jörg; Roth, Bernhard; Overmeyer, Ludger (Basel : MDPI AG, 2018)

Long-period fiber gratings (LPGs) are well known for their sensitivity to external influences, which make them interesting for a large number of sensing applications. For these applications, fibers with a high numerical ...
Longitudinal conductivity of LaF3/SrF2 multilayer heterostructures

Vergentev, Tikkhon; Banshchikov, Alexander; Filimonov, Alexey; Koroleva, Ekaterina; Sokolov, Nikolay; Wurz, Marc Christopher (Abingdon : Taylor and Francis Ltd., 2016)

LaF3/SrF2 multilayer heterostructures with thicknesses of individual layers in the range 5-100 nm have been grown on MgO(100) substrates using molecular beam epitaxy. The longitudinal conductivity of the films has been ...
Multi-anionic and -cationic compounds: New high entropy materials for advanced Li-ion batteries

Wang, Qingsong; Sarkar, Abishek; Wang, Di; Velasco, Leonardo; Azmi, Raheleh; Bhattacharya, Subramshu S.; Bergfeldt, Thomas; Düvel, Andre; Heitjans, Paul; Brezesinski, Torsten; Hahn, Horst; Breitung, Ben (Cambridge : Royal Society of Chemistry, 2019)

In the present work, a new class of high entropy materials for energy storage applications is introduced. Multi-anionic and -cationic compounds are prepared by facile mechanochemistry using a recently designed multi-cationic ...
