Embedding nanoparticles in a responsive polymer matrix is a formidable way to fabricate hybrid materials with predesigned properties and prospective applications in actuators, mechanically tunable optical elements, and electroclinic films. However, achieving chemical compatibility between nanoparticles and organic matter...

Period of Oscillatory Motion of a Camphor Boat Determined by the Dissolution and Diffusion of Camphor Molecules.

The journal of physical chemistry. B

Here, we investigated the oscillatory motion of a camphor boat on water to clarify how the dynamics of camphor concentration profile determines the period of oscillation. The boat, which was made of a plastic plate and a camphor disk,...

Synthesis and structure analysis of ferrocene-containing pseudopeptides.

Biopolymers

Biopolymers. 2017 Oct 23; doi: 10.1002/bip.23072. Epub 2017 Oct 23.

Ferrocene with its aromaticity and facile redox properties is an attractive moiety to be incorporated into functional moieties. Medicinal applications of ferrocene are well known and ferrocene itself shows cytotoxic and antianemic properties. In this article, we will describe...

Phys Rev Lett. 2020 Jan 24;124(3):030501. doi: 10.1103/PhysRevLett.124.030501.

We consider the precision Δφ with which the parameter φ, appearing in the unitary map U_{φ}=e^{iφΛ}, acting on some type of probe system, can be estimated when there is a finite amount of prior information about φ. We show...

The demonstration of miniature atomic clocks (MACs) based on coherent population trapping (CPT) with improved mid- and long-term frequency stability benefits from the implementation of additional stabilization loops to reduce temperature-induced light-shift effects. In this article, we report and...

Credibility of Evolutionary Events in Gene Trees.

Based on the classical non-parametric bootstrapping for phylogenetic trees, we propose a novel bootstrap method to define support for gene duplication and speciation events. By comparing bootstrap gene trees to the original gene tree, we calculate support for evolutionary...

Noble metal nanolayers on flat substrates are often deposited with the use of semiconductor interlayers, which may strongly interact with the noble metal overlayer. We investigated the crystallinity, atomic concentration profile and optical parameters of ≈35 nm-thick silver and...

Strongly Correlated Quantum Droplets in Quasi-1D Dipolar Bose Gas.

Physical review letters

Ołdziejewski R, Górecki W, Pawłowski K, Rzążewski K.

Phys Rev Lett. 2020 Mar 06;124(9):090401. doi: 10.1103/PhysRevLett.124.090401.

We exploit a few- to many-body approach to study strongly interacting dipolar bosons in the quasi-one-dimensional system. The dipoles attract each other while the short range interactions are repulsive. Solving numerically the multiatom Schrödinger equation, we discover that such...
