Summary: The manuscript reports a strategy for synthesizing double-stranded alternating heterodinucleoside polytriazoles through a cycloaddition polymerization process. The distinct self-assembly behaviors between the polytriazoles and their monomeric precursors show potential for developing novel artificial nucleic acids that can induce the formation of helical nanofibers. The approach could be extended to more complex nucleobase sequences for iterative polymerization of nucleoside monomers.

Summary: Alkyne-azide cycloaddition (AAC) is a widely used reaction in polymer and materials sciences. The challenge of modifying polytriazoles with inert functional groups has been solved by developing a multicomponent polymerization (MCP) using diynes, diazides, and electrophiles. The MCP method allows for the synthesis of 1,4,5-trisubstituted polytriazoles (1,4,5-PTAs) with high yields and molecular weights. By optimizing the ratio of functionalized PTAs to non-functionalized PTAs, the solubility of the obtained products was improved. The resulting nanoparticles can act as nanocatalysts in the AAC reaction with excellent catalytic efficiency.

Summary: A rare phenomenon of inverse excitation-dependent dual-band emission is achieved in 0D Cs2InBr5, where initial compression leads to blue-shifted STE emission while higher pressure induces a new defect-related localized exciton emission. The high-energy emission from the intrinsic STE state is only observed under low-energy excitation, suggesting excitation-dependent multiple excited states in high-pressure Cs2InBr5.

Summary: Controlling the fluorescence properties of organic molecules in the aggregation state and understanding the structure-activity relationship are crucial for developing excellent luminophors with tunable solid emission. In this study, a series of carbazole based donor/acceptor type fluorophores functionalized with different substituents were designed and synthesized, exhibiting unique solid luminescence influenced by the substituents. Substituted compounds like CZ-H, CZ-Br, and CZ-CN displayed aggregation-induced emission (AIE), while CZ-N exhibited crystallization-induced emission (CIE) due to packing differences. Introducing bromide substituents in the N-butyl chain of carbazole led to a red-shift in solid emission wavelength, showcasing unique molecular conformation and packing arrangements.

Summary: In this study, a novel hybrid organic-inorganic Zr(IV) metal halide, ((CH3)(4)N)(2)ZrCl6, was reported to exhibit excitation-dependent luminescence across the full visible region. The material demonstrated unexpected high symmetry and formed a unique 0D structure. Three different emission groups were observed under variable excitation, including free-exciton fluorescence, thermally activated delayed fluorescence (TADF), d-d transitions of Zr(IV), and self-trapped exciton (STE) emission. This work presents the first example of a 0D organic-inorganic metal halide with distinctive excitation-dependent full-visible-spectrum luminescence via four different emission mechanisms.

Summary: Semiconductor nanowires have great potential in controlling light-matter interactions. In this study, the polarization dependence of photoluminescence (PL) properties from silicon carbide nanowire (NW) arrays doped with oxygen and erbium ions was investigated. The anisotropic behavior of visible NW PL for different polarizations was observed and found consistent with simulations and the classical dielectric contrast model. The effect of this anisotropy on carrier dynamics and erbium-induced 1540 nm emission was also explored, demonstrating the potential for applications in chip-scale photonics and quantum photonics.

Summary: Despite the initial promise of photothermal ablation (PTA) therapy, the inability to completely ablate large tumors is problematic. This study developed a smart photothermal nanosystem (PBM) based on FDA-approved Prussian blue (PB) nanoparticles, doped with Mn (III) to address this issue. The PBM nanosystem amplified the PTA-induced cGAS-STING pathway, leading to a robust immune response and suppression of both local residual and distant tumors.

Summary: In this work, we developed an automated and fully-integrated nucleic acid analyzer by combining automated liquid handling robot technique with microfluidic droplet-based real-time PCR assay technique. The analyzer could perform multiple operations including sample introduction, nucleic acid extraction, reverse transcription, sample droplet generation, PCR amplification, and real-time dual fluorescence detection. We minimized the analyzer size to 50 x 45 x 45 cm (length x width x height) and reduced the instrument cost to approximately $900 with a single analysis cost less than $5. The analyzer was successfully applied to identify eight types of influenza pathogens in human throat swabs, showing consistent results with the colloidal gold method.

Summary: A simple method for preparing large-area CLCE films by adding a chain-transfer agent is reported in this study. The TPU/CLCE/TPU sandwich films, obtained by fixing CLCE films between two thermoplastic polyurethane (TPU) films, exhibit mechanochromic behaviors. The selective Bragg reflection band shifts to short wavelength due to the decrease of helical pitch of CLCE film upon stretching. Based on this structural color change, a flower pattern can emerge or vanish upon stretching. Moreover, a two-dimensional tetragonal grating with elasticity is prepared. The TPU/CLCE/TPU films can be facilely fabricated over large area and used as car films.

Summary: Hyperbranched poly(a-amino acid)s have attracted attention for their biocompatibility, degradability, and bioactivity. Unique polymerization reactions of di-NNPC resulted in hyperbranched polypeptoids instead of gels. The molecular weights of the hyperbranched polypeptoids were controlled by tuning the initial concentrations of monomer and basic catalyst. The residual glycine pendant groups on the polymer chains were used for Gd3+ complexation and post-modification, making the hyperbranched polypeptoids multifunctional single molecular micelles applicable as contrast agents and probes in magnetic resonance imaging and photoluminescence.

Summary: To address the plastic waste crisis, there are efforts to develop sustainable polymer materials that can degrade through disposing and decomposing to small molecules (DDM) or via chemical recycling to monomers (CRM). Polyacetals, a type of pH-responsive polymers, can degrade under acidic conditions but remain stable under neutral and basic conditions. Their synthesis through cationic ring-opening polymerization (CROP) has challenges but recent advancements in CRM have renewed interest in this method. Polyacetals offer recyclable materials with DDM and CRM potential, expanding closed-loop recycling options and improving degradation properties of traditional polyesters and polyolefins.

Summary: To overcome hypoxia in tumor therapy, a hypoxia-activated prodrug of docetaxel (DTX-PNB) was synthesized and self-assembled with indocyanine green (ICG) to form a combination nanomedicine ISDNN. Through molecular dynamic simulation, the construction of ISDNN was accurately controlled, resulting in uniform size distribution and high drug loading capacity of up to 90%. In the hypoxic tumor environment, ISDNN exhibited ICG-mediated photodynamic therapy and aggravated hypoxia to enhance DTX-PNB activation for chemotherapy, leading to improved antitumor efficacy.

The surge/sway and heave motions of the platform are significantly affected by the ISW. Compared with the passive tensioner, the active tensioner can reduce the amplitude of the piston rod motion at low frequency and is more stable at high frequency.
