Counterion Dependent Side‐Chain Relaxation Stiffens a Chemically Doped Thienothiophene Copolymer
Advanced Functional Materials, EarlyView.Oxidation of a thienothiophene copolymer, p(g3TT‐T2), via different doping strategies and dopant molecules resulted in materials with similar oxidation levels and a high electrical conductivity of ≈100 S cm−1. However, mechanical properties varied significantly, with sub‐glass transition temperatures and elastic moduli spanning from –44°C to –3°C and ...

Magnetic Force Microscopy Signatures of Higher‐Order Skyrmions and Antiskyrmions
Advanced Functional Materials, EarlyView.Magnetic force microscopy operated under vacuum conditions enables the qualitative identification of higher‐order skyrmions and antiskyrmions in Co/Ni multilayers at room temperature. Distinct stray‐field contrast signatures arise from vertical Bloch lines and complex domain‐wall configurations.

Domain Wall Rebounds Driven by Competing Entropic and Spin‐Transfer Torques in Cylindrical Nanowires
Advanced Functional Materials, EarlyView.Domain‐wall motion in cylindrical magnetic nanowires driven by nanosecond current pulses. Low current densities efficiently displace domain walls, whereas higher currents cause rebound at the wire ends. The effect results from the interplay between spin‐transfer torque and thermally induced processes, highlighting the role of thermal gradients in ...

Immunocytochemistry of the cell nucleus
Electron Microscopy Reviews, 1990This electron microscopic review addresses in situ immunocytochemistry of the mammalian cell nucleus with special reference to the use of autoantibodies, which are the major source of antinuclear antibodies. The localization of many key nuclear antigens is documented and immunocytochemical data are related to the major functional processes of ...

Hyperthermia and the Cell Nucleus
Radiation Research, 1982Recent reviews document that hyperthermic shock inhibits the major nuclear activities, including semiconservative DNA replication (1, 2). These inhibitions may result either from a direct effect of heat on the cell nucleus or as a consequence of changes in other cell compartments [e.g., cell membrane damage (3)].

ABSTRACT The ultimate book on the nucleus would require about a million pages just to present the complete base sequence of DNA in a single human nucleus, alphabetically. The three volumes of The Cell Nucleus, of course, make no pretense of offering that kind of information, but they provide a wide range of up-to-date information on the structure and ...

Trends in Genetics, 1990
Purified DNA can be assembled into structures that closely resemble cell nuclei. The cell-free systems that allow this can be exploited to study assembly pathways for several components of the nucleus. They also offer great opportunities for the experimental analysis of nuclear function.

Nucleus is a specialized organelle that serves as a control tower of all the cell behavior. While traditional biochemical features of nuclear signaling have been unveiled, many of the physical aspects of nuclear system are still under question. Innovative biophysical studies have recently identified mechano-regulation pathways that turn out to be ...
