Summary: Dielectric elastomer generators (DEGs) show promise in replacing expensive power take-off systems with cheap direct-drive generators for sea wave energy converters. A pressure differential wave energy converter with a DEG power take-off was introduced, demonstrating the potential for large power capture in a wide range of sea states. A modeling approach based on potential-flow theory and electroelasticity theory was proposed and validated through experimental data, proving its effectiveness as a design and prediction tool.

Summary: This study examines the impact of ligands' energy levels on the thermal dependence of lanthanide emission and successfully creates new molecular nanothermometers. The results show that the difference in energy levels between the triplet state and the excited state of lanthanides is a key factor controlling the thermal dependence of emission intensity. Moreover, the energy gap between ligand-centered states also affects the thermal behavior.

Summary: This study investigated the effects of different functional groups on the dielectric behavior of coordination polymers. The results showed that electron-donating and electron-withdrawing groups altered the polarity of the polymers, which in turn affected the dielectric constant. Theoretical calculations supported the experimental findings and revealed distinct electronic behaviors and wide bandgaps in these compounds. This study provides important information for further research on the effects of different functional groups on the dielectric properties of coordination polymers.

Summary: This experimental study demonstrates bridge-coupled metallo-dielectric nanolasers that can operate in different modes at room temperature, with stable operation supported by varying the length of the bridge. Both designs have been fabricated and characterized, confirming their lasing behavior through spectral evolution, light-in light-out characteristics, and emission linewidth narrowing. The operating mode is identified through near-field and far-field emission pattern measurements, marking the first demonstration of mode selection in bridge-coupled metallo-dielectric nanolasers.

Summary: Polymer film capacitors are important components for high-power applications, but their low energy density has made it difficult to meet the requirements of energy system miniaturization. Various strategies to improve the energy density of polymer dielectrics have been investigated, with particular interest in the construction of multilayer-structure composites. However, comprehensive and systematic reviews on the design principles and potential regulation mechanisms of multilayer interfaces are still lacking. This review summarizes recent progress in polymer-based multilayer-structure composite dielectrics, focusing on multilayer interface engineering and discussing various factors that affect their performance.

Summary: In this study, a color-tunable metasurface is demonstrated using numerical analysis. By employing a low-refractive-index dielectric material Si3N4, which leaks the electric field to its surroundings, the potential of these metasurfaces to achieve color-tuneable devices with encrypted watermarks is investigated through simulations. This modulation of colors can be applied to anti-counterfeiting and dynamic displays.

Summary: This study proposes a multi-functional metamaterial absorber based on doped silicon, which achieves broadband absorption through resonance and impedance matching, and precise amplitude control by controlling the pump luminous flux. By replacing the medium-doped silicon material with highly doped silicon material and combining it with microfluidic control, a high sensitivity sensor is realized. Experimental verification demonstrates the potential of this absorber in sensing applications.

Summary: A deep-ultraviolet narrowband tunable filter with a central wavelength of 225.0 nm was designed, fabricated, and experimentally demonstrated. The filter showed good performance with a transmittance of about 42.1% at 225.0 nm and a FWHM of around 1.2 nm. By changing the incident angle, the central wavelength could be tuned from 225.0 to 224.5 nm.

Summary: A simple 2D model is used to study the formation of bubbles in a plasma wakefield accelerator. The results show that the bubble consists of two parts: a laminar flow and a turbulent flow. The laminar flow remains stable even when symmetry breaks, and there is no transverse wakefield inside the bubble in the case of laminar flow and nonrelativistic plasma electrons.

Summary: In this paper, a method of constructing a discrete nonlinear accelerator lattice is presented, along with an integrator that has an approximate integral of motion. The integrator, which is connected to a real lens arrangement, preserves a Hamiltonian in normalized coordinates with a given accuracy. By utilizing known algorithms of high-order symplectic integrators, several nonlinear lattices are generated. A new lattice design based on the Ruth and Yoshida integrators is proposed, which can be experimentally tested at existing accelerator facilities and Paul traps.
