'Jaroslav Frnda' 'Jan Nedoma' 'Luís Castedo Ribas'] The introduction of 5G with excessively high speeds and ever-advancing cellular device capabilities has increased the demand for high data rate wireless multimedia communication. Data compression, transmission robustness and error resilience are introduced to meet the…

The filling of channels in porous media with particles of a material can be interpreted in a first approximation as a packing of spheres in cylindrical recipients. Numerous studies on micro- and nanoscopic scales show that they are, as a rule, not ideal cylinders. In this paper, the channels, which have an irregular…

Sphere packings in circular cylinders have attracted substantial research interest, among which the discovery of chiral helical structures is the most iconic. However, recent experimental results on zebrafish do not match the known packing structures in circular cylinders. To account for the inherent imperfections of…

'Samuel Olsson' 'Robert Tkach'] In optical communications, sphere shaping is used to limit the energy of lightwaves to within a certain value over a period. This minimizes the energy required to contain information, allowing the rate of information transmission to approach the theoretical limit if the transmission…

Restriction enzymes recognize and bind to specific sequences on invading bacteriophage DNA. Like a key in a lock, these proteins require many contacts to specify the correct DNA sequence. Using information theory we develop an equation that defines the number of independent contacts, which is the dimensionality of the…

We present a quantitative means for classifying the shape of molecular dynamics simulated peptide amphiphile micelles (PAMs) that is both consistent with existing metrics and extendable to estimating shape-dependent free energy contributions. The presented framework not only outlines an approach for characterizing the…

Polymorphism in molecular crystals influences their properties and performance. Crystal structure prediction (CSP) can help explore the crystal structure landscape and discover potentially stable polymorphs computationally. We present a new version of the Genarris open-source code, which generates random molecular…

'M. Albooyeh' 'Rituraj Rituraj' 'Theodosios D. Karamanos' 'R. Alaee' 'Sergei Tretyakov' 'Carsten Rockstuhl' 'S. Fan'] We provide a theoretical description of light scattering by a spherical particle whose permittivity is modulated in time at twice the frequency of the incident light. Such a particle acts as a…

'Peng Li' 'Bingyan Wei' 'Jianlin Zhao' 'Sheng Liu'] Abstract: Overcoming the inherent phase-only modulation limitation of conventional Pancharatnam-Berry (PB) elements, we propose a checkerboard-encoded PB element that enables simultaneous amplitude and phase modulation through PB phase engineering. This single-element…

This article presents an overview about the state of the art in the development of structured packings for distillation applications. The focus is on highlighting different approaches including heuristic development cycles, the development of new packing structures, 3D-printing as tool for manufacturing, and…

An important aim of the development of selective plane illumination microscopy (SPIM) is to present a completely open and flexible microscope set-up for nonspecialist users. Here, we report Structured SPIM (SSPIM), which provides an open-source, user-friendly and compact toolbox for beam shaping that can generate…

We present a simple yet efficient random (brute-force) algorithm for constructing solvated molecular systems. By placing solvent molecules at random positions and orientations within a simulation box, we circumvent the complexities typically associated with more sophisticated packing algorithms. The main computational…

Four new thiourea-functionalized ligands based on aminopyrazole frameworks were synthesized and characterized by NMR spectroscopy, mass spectrometry, and single-crystal X-ray diffraction. The crystal structures of all ligands, as well as a zinc(II) chloride complex, were determined. Excitation and emission properties…

Orbital angular momentum (OAM), which describes tailoring the spatial physical dimension of light waves into a helical phase structure, has given rise to many applications in optical manipulation, microscopy, imaging, metrology, sensing, quantum science, and optical communications. Light beams carrying OAM feature two…

Coherent structured illumination microscopy (c-SIM) is a synthetic aperture optical technique for sub-diffraction limit imaging that extends the utility of traditional SIM to non-fluorescent samples. Here, we present a complementary 5-beam implementation of c-SIM that provides enhanced optical sectioning compared to…

The self-organization of colloidal nanoparticles into complex structures, both in equilibrium and out-of-equilibrium, is a critical area in colloidal science with potential applications in creating new functional materials. While equilibrium assemblies yield thermodynamically stable and periodic structures…
