Gravitational anyons [PDF]

Physical Review Letters, 1990
Summary: We describe some novel effects generated by the gravitational Chern-Simons term similar to those induced by its electromagnetic counterpart. In particular, a structureless particle source generates a gravimagnetic field. Conversely, it causes a spinning source to contribute to the static Newtonian potential, thereby violating the equivalence ...

Self‐Cleaning Sensor Surfaces for Long‐Term Environmental Monitoring

Advanced Engineering Materials, EarlyView.
Long‐term use of unattended outdoor sensors without soiling or biofouling is achieved through generation of a micro‐ and nanorough cuvette surface by combing hydrophobic nanoparticles with fluorinated polymers, crosslinked and surface‐attached through CHic chemistry. The coating demonstrates self‐cleaning behavior and prolonged outdoor stability, which

Test of the Law of Gravitation at Small Accelerations

, 2011
Newton's Law of Gravitation has been tested at small values a of the acceleration, down to a a parts per thousand 10(-10) ms(-2), the approximate value of MOND's constant a (0). Within experimental errors no deviations from Newton's Law were found.

Feasibility and Limitations of the Advanced Replica Process for Bioactive Glasses

Advanced Engineering Materials, EarlyView.
Periodic 3D‐printed Kelvin‐cell templates enable a controlled advanced replica process for fabricating highly porous glass lattices. Across P45K9, 45S5, and 13–93, material‐dependent differences in coating, burnout, and shrinkage lead to distinct strut morphologies, while comparable final porosities of 83%–88% are retained.

Linköping University Post Print GRAVITATION AS A CASIMIR EFFECT GRAVITATION AS A CASIMIR EFFECT

, 2009
We describe how dispersion forces between two atoms in ordinary electromagnetism come about and how they may be derived. Then we introduce hypothetical particles interacting with a harmonic oscillator interaction potential.

Stratified scalar field theories of gravitation with self-energy term and effective particle Lagrangian

European Physical Journal C: Particles and Fields, 2018
We construct a general stratified scalar theory of gravitation from a field equation that accounts for the self-interaction of the field and a particle Lagrangian, and calculate its post-Newtonian parameters.

Programmable Soft Actuator with Multi‐Responsiveness Based on Conductive MOF‐Liquid Crystal Polymer Composite

Advanced Functional Materials, EarlyView.
A sequential dual‐alignment strategy independently programs the orientation of conductive metal‐organic framework (c‐MOF) microrods and liquid crystals within a composite film. This approach creates an asymmetric bilayer structure that enables precise, multi‐responsive actuation.

Exotic matter and MOND as special cases of a more general solution in pure general relativity

Frontiers in Astronomy and Space Sciences
Several solutions have been proposed to explain the dark matter (DM) component, but two explanations stand out. The most widely accepted is the assumption of the existence of exotic matter, and the second is the assumption of a modification of ...

Multistage, Self‐Sensing Artificial Muscles With Coordination From Liquid Crystal Elastomer‐Graphene Composite Fibers

Advanced Functional Materials, EarlyView.
Inspired by skeletal muscles’ precision and endurance, CoilLCE integrates a self‐sensing liquid crystal elastomer/graphene artificial muscle with an embedded Joule‐heating copper coil, enabling closed‐loop multistage actuation with programmable intermediate states (strain accuracy of 2%), and antagonistic coordination (32% total strain). These features
