Membrane fission is an essential cellular process by which continuous membranes split into separate parts. We have previously identified CtBP1-S/BARS (BARS) as a key component of a protein complex that is required for fission of several endomembranes, including basolateral post-Golgi transport carriers. Assembly of this complex occurs at the Golgi apparatus, where BARS binds to the phosphoinosi...
Medium-mass neutron-rich nuclei are important for nuclear structure investigations (e.g. shell evolution with neutron excess) and nuclear astrophysics (e.g. r-process in nucleosynthesis). However, these investigations are limited because of the difficulties in producing medium-mass nuclei with a large neutron excess. The traditional way for producing neutron rich nuclei was fission of actinides...
This work investigates the unimolecular dissociation of the 2-buten-2-yl radical. This radical has three potentially competing reaction pathways: C-C fission to form CH3 + propyne, C-H fission to form H + 1,2-butadiene, and C-H fission to produce H + 2-butyne. The experiments were designed to probe the branching to the three unimolecular dissociation pathways of the radical and to test theoreti...
A review of the characteristic features found in fully energy-damped, binarydecay yields from light heavy-ion reactions with 20 ≤ Atarget+Aprojectile ≤ 80 is presented. The different aspects of these yields that have been used to support models of compound-nucleus (CN) fission and deep-inelastic dinucleus orbiting are highlighted. Cross section calculations based on the statistical phase space ...
With few exceptions the endoplasmic reticulum (ER) is considered a continuous system of endomembranes within which proteins and ions can move. We have studied dynamic structural changes of the ER in hippocampal neurons in primary culture and organotypic slices. Fluorescence recovery after photobleaching (FRAP) was used to quantify and model ER structural dynamics. Ultrastructure was assessed by...
Many elements on Pd electrodes were confirmed by several analytic methods; reaction products with the mass number up to 208 are deposited on palladium cathodes, which were subjected to electrolysis in a heavy water solution at high pressure, temperature, and current density for prolonged time. These masses were composed of many elements ranging from hydrogen to lead. Extraordinary changes of th...
The reaction mechanisms best suited for the production of neutron-rich nuclei, fragmentation and fission, are discussed. Measurements of the production cross sections of reaction residues together with model calculations allow to conclude about the expected production rates of neutron-rich isotopes in future facilities.
