Summary: This study focused on using poly(acrylic acid) block copolymers as stabilizers to modify the surfaces of polymer particles during dispersion polymerization. Polystyrene-block-poly(acrylic acid) was found to have better control over particle size range and surface density compared to poly(acrylic acid) homopolymer. The impact of heterogeneity between the polymer species of the particle core and attached polystyrene or PMMA chains in the poly(acrylic acid) block copolymers was also investigated.

Summary: The length of the corona in spherical micelles of block copolymers is determined by the molecular weight of the corona-forming block relative to that of the core block before assembly. By selectively extending the corona block using surface-initiated polymerization, it is possible to convert crew-cut micelles to hairy micelles while maintaining the spherical shape. This method allows for the creation of micelles with different corona lengths and shapes, providing insight into the packing problem in copolymer micelle assembly.

Summary: A novel double-resonant plasmonic substrate for fluorescence amplification in a chip-based apta-immunoassay was reported. The substrate relies on the plasmon-enhanced fluorescence (PEF) effect to amplify the fluorescence signal. It can potentially be used for multiplexing applications. In a malaria apta-immunoassay, the substrate successfully detected Plasmodium falciparum lactate dehydrogenase (PfLDH) in human whole blood with high sensitivity and without complex pretreatments.

Summary: Heavy metallic salts can induce supramolecular polymerization and fibrilization in liquid crystalline block copolymers. The block copolymer monomers can bind with the metallic salts to form small aggregates, which act as seeds to trigger the supramolecular polymerization of the rest of the monomers. The length of the resulting supramolecular polymer fibrils is linearly proportional to the ratios between the block copolymer and the metallic salts, and is influenced by the choice of metallic cations and counterions. This method can be used to polymerize different block copolymer monomers to produce pentablock supramolecular polymers in a one-pot manner.

Summary: The development of block copolymer grafted SiNP as functional nanofiller for nanocomposites-based PEM showed promising results in improving thermal, mechanical, and chemical stabilities, as well as proton conductivity. The structure, sequence, and length of polymer chains on SiNP surface were found to significantly influence the properties of the nanofiller and ultimately alter the PEM properties. The clear dependence of PEM properties on the architecture of BC-g-SiNP highlights the importance of understanding the impact of chain length and sequence on nanofiller performance.

Summary: The research demonstrates that the nature of the substrate has a significant impact on the self-assembled morphology and surface patterns of bottlebrush block copolymers with different side-chain lengths in films, despite the typical tendency of these polymers to form lamellar structures. By manipulating the substrate chemistry, unique morphologies can be induced in bottlebrush block copolymer films.

Summary: A platform is introduced for creating a reusable and highly efficient low band gap photocatalyst by confining gold nanoparticles in nanopatterned Si monolith. This design prevents agglomeration of nanoparticles and enhances redox reaction efficiency while minimizing rapid recombination of photogenerated charge carriers. Compared to bare silicon and randomly dispersed AuNPs on silicon, the confined structure achieved near complete degradation of MO due to more active sites and effective Schottky junctions.

Summary: One-step sequence-selective block copolymerization requires strict catalytic control of monomer activity and enchainment order, especially for A(n)B(m)-type block copolymers from simple binary monomer mixtures. In this study, ethylene oxide (EO) and N-sulfonyl aziridine (Az) form a valid pair with a bicomponent metal-free catalyst. The optimal Lewis acid/base ratio allows the two monomers to block-copolymerize strictly in a reverse order (EO-first) compared to the conventional anionic route (Az-first). The livingness of the copolymerization enables the one-pot synthesis of multiblock copolymers by adding mixed monomers in batches. Calculation results suggest that the Janus effect of Lewis acid on the two monomers is crucial for enlarging the activity difference and reversing the enchainment order.

Summary: This study investigates the influence of the polarity of polymer matrices on persistent room-temperature phosphorescence (pRTP). It is discovered that intense phosphorescence emission can be achieved in highly polar matrices such as polyacrylic acid (PAA). The dipole-dipole interaction between the polar fluorophore and polar matrix is proposed to stabilize the excited state and facilitate the generation of efficient room-temperature phosphorescence emissions.

Summary: We investigate the interface properties between WSi2N4 and Mo2B, O-modified Mo2B, and OH-modified Mo2B nanosheets. We find that WSi2N4 and Mo2B form n-type Schottky contacts, while functionalizing Mo2B with O and OH leads to the formation of both n-type and p-type ohmic contacts with WSi2N4. Additionally, we demonstrate the emergence of quasi-ohmic contact with ultralow lateral Schottky barrier and zero vertical interfacial tunneling barriers in Mo2B(OH)2-contacted WSi2N4.

Summary: When rare-earth ions are embedded in a ferroelectric material, their photoluminescence can serve as an all-optical probe for temperature, electric field, and mechanical stimulus. However, the impact of ferroelectric phase transitions on photoluminescence is not well understood. In this study, we demonstrate changes in the photoluminescence of green emission bands during critical ferroelectric transitions in an Er-doped BaTiO3 material. We also find that the intensity ratio and wavelength position difference of sub-peaks provide information on the phase transitions.

Summary: In this study, a new spin-gapless semiconductor material CoFeMnSn is reported, and its stable structure and spin-polarized band structure are determined through experimental realization and theoretical calculations. The compound exhibits a high ferromagnetic transition temperature, making it excellent for room temperature applications. The nearly temperature-independent resistivity, conductivity, and carrier concentration of the compound, adherence to the Slater-Pauling rule, and the high intrinsic anomalous Hall conductivity achieved through hole doping further confirm its spin-gapless semiconductor nature. Additionally, the compound's SGS and topological properties make it suitable for spintronics and magneto-electronics devices.
