Summary: The era of miniaturized and customized electronics requires scalable and versatile energy storage devices. Direct ink writing (DIW)-based 3D printing technology has shown potential in manufacturing micro-batteries with design freedom and outstanding performance. However, there are still challenges in terms of manufacturing and printable materials for all 3D DIW printed Li-ion batteries. This study presents a solution by optimizing the rheological properties of DIW printable inks and using UV-curable polydimethylsiloxane (PDMS) and ethoxylated trimethylol-propane triacrylate (ETPTA) monomers to achieve reliable extrusion and high-throughput printed electrolyte layers.

Summary: Plasmonic microbubbles generated by laser irradiated gold nanoparticles have applications in various fields. This paper investigates the hydrodynamics of these bubbles in ferric nitrate solution and discovers the formation of well-defined micro-domes on the sample surface. The nucleation of plasmonic bubbles is found to be associated with the solvothermal decomposition of ferric nitrate, and the bubbles act as templates for the deposition of iron oxide nanoparticles. The research findings provide insights into the phenomena of plasmonic bubble nucleation and pave the way for fabricating three-dimensional microstructures using a common continuous wave laser.

Summary: In this work, block copolymer lithography and ultralow energy ion implantation are combined to create nanovolumes with high concentrations of periodically arranged phosphorus atoms in a p-type silicon substrate. The implanted dopants cause local amorphization of the silicon substrate. Phosphorus is then activated through a solid phase epitaxial regrowth process, preserving their spatial localization. The proposed approach allows for further investigations on modulating the dopant distribution within a silicon substrate at the nanoscale by changing the characteristic dimension of the self-assembled BCP film.

Summary: The combination of enzymes and chemically responsive smart materials has great potential in various fields such as anti-fouling, sensing, and medicine. Liquid crystal elastomers (LCEs) have been recognized as a leading actuator platform due to their programmability and large shape transformations in response to stimuli. In this study, three different hydrolytic enzymes are immobilized into acid-responsive LCEs, enabling the LCEs to be sensitive to lipids, carbohydrates, and peptides. The dye-doped biocatalytic LCEs exhibit color and shape changes when exposed to specific substrates. The versatility of shape changes in the enzyme-containing LCEs is demonstrated using twisted nematic patterning and direct ink writing. A connected array of 3D printed disks, each containing a different enzyme, showcases the LCEs' excellent chemical selectivity. This work introduces a novel platform of versatile bioresponsive color-switchable actuators that can find applications in a wide range of fields.

Summary: The magnetic proximity effect (MPE) and electric-field tunability have opened up a new physical paradigm in the development of nanoscale devices. Using first-principles calculation, we study MPE in a van der Waals heterostructure composed of a monolayer of the Weyl semimetal 1T'-WTe2 and a monolayer ferromagnet CrBr3. The proximity effect results in a 100% spin-polarized half-metallic nature in the heterostructure system, with a spin-splitting of 25 and 10 meV for two spin configurations. This MPE is robust due to orbital hybridization and charge transfer at the interface. The half-metallic nature can be tuned to semiconducting and overlapping states by an external bias, and the proximity interface is highly sensitive to an external electric field.

Summary: The widespread use of hexagonal boron nitride (hBN) in devices embedding two-dimensional materials has made it the most sought after platform for implementing quantum sensing. The negatively charged boron vacancy (VB-) in hBN plays a prominent role, as it can be easily generated and its spin population can be initialized and read out by optical means at room temperature. However, the low quantum yield hinders its widespread use as an integrated quantum sensor. In this study, an emission enhancement of 400 was achieved by using nanotrench arrays compatible with coplanar waveguide (CPW) electrodes, leading to an enhanced DC magnetic field sensitivity as high as 6 x 10(-5) T/Hz(1/2)。

Summary: In this study, we investigate the photoluminescence of single CsPbBr3 nanocrystals at cryogenic temperatures to reveal the size-dependence of their spectral features in the intermediate quantum confinement regime. We analyze the bright triplet exciton energy splittings, trion and biexciton binding energies, and optical phonon replica spectrum. Our results indicate that the bright triplet energy splittings are consistent with a pure exchange model, and the variety of polarization properties and spectra observed can be explained by considering the orientation of the emitting dipoles and the populations of the emitting states.

Summary: Light-matter interactions in optical cavities are crucial for integrated quantum photonics applications. Hexagonal boron nitride (hBN) has emerged as a promising van der Waals platform for quantum emitters, but progress has been hindered by the inability to simultaneously engineer an hBN emitter and a narrow-band photonic resonator. In this study, we overcome this challenge by demonstrating deterministic fabrication of hBN nanobeam photonic crystal cavities with high quality factors across a broad spectral range. We also create a monolithic cavity-emitter system tailored for a blue quantum emitter, induced deterministically through electron beam irradiation. This work presents a promising approach for scalable on-chip quantum photonics and opens up possibilities for quantum networks based on van der Waals materials.

Summary: Negatively charged boron vacancies (VB-) in hexagonal boron nitride (hBN) have become of interest as spin defects for quantum information processing and quantum sensing. This study investigates the switching of charge states of VB defects in hBN under laser and electron beam excitation, demonstrating deterministic and reversible switching between the -1 and 0 states controlled by excess electrons or holes injected into hBN by a layered heterostructure device. This work provides a means to monitor and manipulate the charge state of VB defects, enabling the stabilization of the -1 state necessary for spin manipulation and optical readout.
