Vat Photopolymerization of High Molecular Weight Polymer Latexes with <i>Pseudothermoplastic</i> Properties for Recyclability Abstract Additive manufacturing (AM), or 3D printing, has rapidly advanced due to its customization, speed, and precision manufacturing. Traditional vat photopolymerization (VPP) often produces densely cross‐linked, brittle, and non‐reprocessable materials, contributing to plastic waste generation. To address these issues, a UV‐reactive latex formulation combining water‐dispersed thermoplastics with a minimal amount of photocurable water‐soluble additive yielding reprocessable pseudothermoplastic materials are proposed. The selection of the water‐soluble additive is crucial not only to enable the printing of high molecular weight thermoplastics with exceptional resolution and tunable properties but more importantly also to retain the properties of the initial latex‐containing polymer while tackling reprocessability issues in photoprinted materials. Reprocessability is demonstrated using traditional manufacturing techniques (e.g., injection, hot‐pressing) as well as extrusion 3D printing. Furthermore, optimized photocurable latex resins are suitable for two‐photon 3D laser printing, enabling the miniaturization of features using the materials reported herein. This innovation opens new pathways for creating reprocessable, high‐performance 3D‐printed materials with on‐demand properties.

Exploring the Recent Progress in InP Quantum Dots and QLEDs: Advances in Synthesis, Architecture, and Applications Abstract Indium phosphide (InP) quantum dots (QDs) have emerged as eco‐friendly alternatives to cadmium‐based QDs, offering high tunability, excellent color purity, and promising potential for next‐generation optoelectronic devices such as quantum dot light‐emitting diodes (QLEDs). However, their integration into commercial technologies continues to face critical challenges, most notably, the enhancement of photoluminescence quantum yield (PLQY) at the material level and the external quantum efficiency (EQE) at the device level. Although recent advances in colloidal synthesis and surface engineering have led to significant improvements in PLQY, effectively transferring these enhancements to achieve high EQE in QLEDs remains a major hurdle due to limitations in charge injection, charge balance, and interfacial losses. This review provides a comprehensive overview of the progress in InP QD development, focusing on key advancements in colloidal synthesis, core/shell engineering, charge transport layers, interfacial modification, and carrier dynamics. The historical evolution of InP QDs from their initial synthesis in 1989 to their growing role in QLEDs post‐2011 is examined in detail, along with persistent issues such as parasitic emission, charge imbalance, and device instability. Finally, the review explores emerging applications in flexible electronics, wearable displays, a nd high‐resolution LED arrays, and suggests future research directions aimed at enhancing efficiency, stability, and scalability for commercial deployment.

Structural, thermal, and radiation shielding properties of antimony-doped zinc borate glasses Antimony zinc borate glasses with compositions (45-m)ZnO-(55-n)B<sub>2</sub>O<sub>3</sub>-(m + n)Sb<sub>2</sub>O<sub>3</sub> (0 ≤ m, n ≤ 15 mol%) were synthesized via the melt-quenching technique to investigate the impact of Sb<sub>2</sub>O<sub>3</sub> substitution on structural, thermal, and radiation shielding properties. X-ray diffraction confirmed the amorphous nature of the synthesized glass samples. Fourier-transform infrared spectroscopy revealed significant structural rearrangements, including an increase in non-bridging oxygen content with rising Sb<sub>2</sub>O<sub>3</sub> concentrations, as evidenced by the shifting and intensification of characteristic absorption bands. Differential thermal analysis demonstrated that the glass transition temperature decreased from 580 °C to 490 °C with increasing Sb<sub>2</sub>O<sub>3</sub>, while the thermal stability parameter (ΔT) improved from 144 °C to 256 °C, particularly when B<sub>2</sub>O<sub>3</sub> was replaced. Density increased from 3.121 g/cm<sup>3</sup> to 3.836 g/cm<sup>3</sup>, and molar volume expanded from 24.01 cm<sup>3</sup>/mol to 31.16 cm<sup>3</sup>/mol. Radiation shielding performance was significantly enhanced: at 10 MeV, the linear attenuation coefficient increased from 0.0768 cm<sup>-1</sup> to 0.1142 cm<sup>-1</sup> (~ 49%) when replacing B<sub>2</sub>O<sub>3</sub> and to 0.0983 cm<sup>-1</sup> (~ 28%) when replacing ZnO. The half-value layer decreased from 9.02 cm to 6.07 cm at 15 mol% Sb<sub>2</sub>O<sub>3</sub>, confirming improved photon attenuation. Overall, this work offers valuable insights into the interplay between composition, structure, and functional properties in Sb<sub>2</sub>O<sub>3</sub>-doped zinc borate glasses.

Direct Integration of Functionalized Bridges by One‐Step Superacid‐Catalyzed Reaction to Fabricate Porous Polymers for CO <sub>2</sub> Capture and Separation A novel class of ultra-microporous functionalized porous organic polymers (POPs) was developed starting from glyoxylic acid as a cross-linker and triflic acid as a catalyst on polyaromatic monomers, generating in situ methine bridges with carboxylic acids. This one-pot synthetic method generated functionalized POPs with high connectivity per each aromatic group and a high density of aliphatic carboxylic acids decorating the pore walls. Remarkably, the functional groups were transformed into esters, Na- and Li-carboxylates by post-synthetic modification with high yields, generating polyionic porous polymers. These porous polymers displayed excellent CO<sub>2</sub> adsorption at 298 K and isosteric heat of adsorption with values as high as 50 kJ mol<sup>-1</sup> for the Na-containing POP endowed with numerous ionic charges, as estimated by direct measurements with microcalorimetry coupled to CO<sub>2</sub> adsorption isotherms. Dynamic breakthrough experiments on self-supporting monolithic composites demonstrated high selectivity for CO<sub>2</sub> adsorption over N<sub>2</sub> up to 500 for diluted streams and 340 under relevant conditions for carbon capture from flue gases (0.15 CO<sub>2</sub> partial pressure).

Strong Proquinoidal Acceptor Enables High‐Performance Ambipolar Organic Electrochemical Transistors Ambipolar organic electrochemical transistors (OECTs) can simplify manufacturing processes and reduce device footprints, yet their performance still lags behind their p-type and n-type counterparts due to limited molecular design strategies. Here, incorporating strong proquinoidal building blocks effectively addresses this challenge is demonstrated. Using a computational acceptor screening approach, three TBDOPV-based polymers are designed and synthesized: P(bgTBDOPV-T), P(bgTBDOPV-EDOT), and P(bgTBDOPV-MeOT2), all exhibiting ambipolar behavior across various donor moieties. Remarkably, P(bgTBDOPV-EDOT) achieves record-high figure-of-merit (µC*) values, reaching 268 F cm<sup>-1</sup> V<sup>-1</sup> s<sup>-1</sup> for p-type and 107 F cm<sup>-1</sup> V<sup>-1</sup> s<sup>-1</sup> for n-type operations. Additionally, P(bgTBDOPV-EDOT) exhibits low operation voltages (V<sub>Th,p</sub> = -0.55 V and V<sub>Th,n</sub> = 0.32 V), with fast response times (τ<sub>on</sub>/τ<sub>off</sub> = 0.48/0.36 ms for p-type and 0.41/0.41 ms for n-type) and enhanced operational stability. Inverter devices based on P(bgTBDOPV-EDOT) show high voltage gains of 173 V/V. Theoretical calculations and data analysis confirm that strong proquinoidal acceptors significantly enhance the delocalization of both positive and negative polarons, offering an effective pathway for higher-performance ambipolar OECT materials.

π‐Extended Heli(aminoborane)s with Highly Bright Circularly Polarized Luminescence and Narrowband Emission Abstract Helical molecular carbons (HMCs) possess high absorption/luminescence dissymmetry factors ( g abs / g lum ) and significant luminescence quantum yield ( Φ lum ), resulting in a high circularly polarized luminescence (CPL) brightness ( B CPL ), which is essential for the development of CPL materials for practical applications. Herein, we designed and synthesized a series of boron‐nitrogen (BN)‐doped HMCs, named π‐extended heli(aminoborane)s ( E[10]HAB‐A , E[10]HAB‐B and E[10]HAB‐C ), consisting of laterally π‐extended [10]helicene skeleton with alternating N and B atoms at the inner rim. The aromaticity, electronic structures, and photophysical properties of E[10]HAB‐A/B/C were systematically investigated through experiments and theoretical calculations. E[10]HAB‐A/B/C displayed remarkable photophysical properties, including high molar extinction coefficient and bright narrowband emission. The isolated enantiomers of E[10]HAB‐A/B/C exhibited intense circular dichroism (CD) and CPL, in which E[10]HAB‐A shows g abs and g lum values up to 0.024 and 0.017, simultaneously with high Φ lum of 82 % and a narrow full width at half maximum of 16 nm. Accordingly, E[10]HAB‐A exhibits a B CPL as high as 583 M −1 cm −1 , which is the largest value among the reported BN‐doped HMCs. Our study indicates that inner rim BN‐doping and π‐extension are effective strategies to achieve high Φ lum and balanced g lum values in HMCs.

Structuring the Future of Cultured Meat: Hybrid Gel-Based Scaffolds for Edibility and Functionality Cultured meat is emerging as a sustainable alternative to conventional animal agriculture, with scaffolds playing a central role in supporting cellular attachment, growth, and tissue maturation. This review focuses on the development of gel-based hybrid biomaterials that meet the dual requirements of biocompatibility and food safety. We explore recent advances in the use of naturally derived gel-forming polymers such as gelatin, chitosan, cellulose, alginate, and plant-based proteins as the structural backbone for edible scaffolds. Particular attention is given to the integration of food-grade functional additives into hydrogel-based scaffolds. These include nanocellulose, dietary fibers, modified starches, polyphenols, and enzymatic crosslinkers such as transglutaminase, which enhance mechanical stability, rheological properties, and cell-guidance capabilities. Rather than focusing on fabrication methods or individual case studies, this review emphasizes the material-centric design strategies for building scalable, printable, and digestible gel scaffolds suitable for cultured meat production. By systemically evaluating the role of each component in structural reinforcement and biological interaction, this work provides a comprehensive frame work for designing next-generation edible scaffold systems. Nonetheless, the field continues to face challenges, including structural optimization, regulatory validation, and scale-up, which are critical for future implementation. Ultimately, hybrid gel-based scaffolds are positioned as a foundational technology for advancing the functionality, manufacturability, and consumer readiness of cultured meat products, distinguishing this work from previous reviews. Unlike previous reviews that have focused primarily on fabrication techniques or tissue engineering applications, this review provides a uniquely food-centric perspective by systematically evaluating the compositional design of hybrid hydrogel-based scaffolds with edibility, scalability, and consumer acceptance in mind. Through a comparative analysis of food-safe additives and naturally derived biopolymers, this review establishes a framework that bridges biomaterials science and food engineering to advance the practical realization of cultured meat products.

Multi-color photonic integrated circuits based on homogeneous integration of quantum cascade lasers We demonstrate an InP-based mid-infrared photonic integrated circuit processed from a wafer in which two distinct quantum cascade laser active regions are grown in different areas on the same InP crystal. A passive InGaAs waveguiding layer is epitaxially deposited on top of the entire InP substrate prior to the laser active region growth to optically couple the lasers emission and to multiplex their emission wavelengths to a single output waveguide. The method demonstrated in this work enables the creation of monolithic photonic integrated circuits with emission wavelength spanning the entire 3-15 µm spectral range and it is of interest for a wide range of applications.

Electrically pumped surface-emitting amplified spontaneous emission from colloidal quantum dots Colloidal quantum dots (QDs) are promising gain materials for realizing solution-processable, wavelength-tunable and low-cost laser diodes. However, achieving electrically pumped amplified spontaneous emission (ASE) in QDs, a prerequisite for lasing, is hampered by the low net optical gain and low current injection of the diodes. Here we demonstrate electrically pumped and surface-emitting ASE from QDs by electro-thermal-optically co-designing a quantum-dot light-emitting diode (QLED) with high net optical gain and high current injection. By developing a top-emitting cavity featuring a Ag/indium-zinc-oxide (IZO) bottom reflective electrode and a IZO/Ag top semi-transparent electrode, the QD emission is effectively resonated; moreover, not only are the surface plasmon polariton losses induced by the metallic electrodes completely eliminated, but also the optical field can be confined primarily within the QDs, resulting in a reduction in loss and a 2-fold enhancement in gain. As a result, the QLED exhibits surface-emitting ASE with a threshold of 10 μJ cm<sup>-2</sup> when pumped by a 100 fs laser at 77 K. By building the QLED directly on a Si heat sink and driving the QLED with an ns-pulsed current source, the Joule heat is effectively dissipated, allowing the QLED to operate stably even at a high current of 2000 A cm<sup>-2</sup>. At 153 K and an injection current of 94 A cm<sup>-2</sup>, the QLED demonstrates surface-emitting ASE with strong directionality, high intensity and narrow bandwidth. The developed QLED, capable of generating surface-emitting ASE, paves the way for the development of QD based vertical cavity surface-emitting laser diodes.

Understanding the Growth and Properties of Sputter‐Deposited Phase‐Change Superlattice Films Abstract Highly textured chalcogenide films have recently gained significant interest for phase‐change memory applications. Several reports have highlighted that programming efficiency improves in devices featuring superlattice stacks, such as Ge 2 Sb 2 Te 5 /Sb 2 Te 3 . However, to be technologically relevant, these films must be deposited on foundry‐scale wafers using processes compatible with back end of the line (BEOL) integration and complementary metal‐oxide‐semiconductor (CMOS) technology, such as, for example, sputter deposition. In this work, we present our observations on the influence of temperature, pressure, and seeding layer on the sputter growth processes of superlattice films. By measuring various material properties, we construct a pseudo‐phase diagram to illustrate the growth of both individual and superlattice films with different periodicities on technologically relevant substrates, namely SiO 2 and carbon. These results provide important insights into the structure, intermixing and electro‐optical properties of superlattice films, and identify optimal growth parameters critical for the manufacturability via sputtering of the material.

Systematic Evaluation of Polarizing Agents for Dynamic Nuclear Polarization Enhanced NMR Dynamic nuclear polarization (DNP) can significantly enhance the sensitivity of nuclear magnetic resonance (NMR) spectroscopy, via the transfer of polarization from unpaired electrons to nuclei. As a result, there is considerable interest in improving DNP efficiency, particularly through the development of new polarizing agents (PAs). Here, a series of 32 PAs, including 26 dinitroxide and 6 hetero biradicals, of which 11 are introduced for the first time, were evaluated for their performance in DNP NMR experiments at magnetic field strengths of 9.4 T, 14.1 T, and 21.1 T. The PAs that are soluble in aqueous media were compared for different proton concentrations. A detailed comparison of the enhancement factors, polarization build-up times, contribution factors, and the resulting overall sensitivity factors is provided. We find that the class of narrow-line-broad-line biradicals not only yield the best performance at high field (21.1 T and 14.1 T) but remain among the best at intermediate fields (9.4 T). Specifically, SNAPol-1 and HyTEK2 are consistently among the best performing radicals at any field. Among the dinitroxides, notably at 9.4 T, the AsymPol-POK and M-TinyPol families stand out in proton-dense aqueous matrices, and a newly developed dinitroxide, NaphPolCbo, is found to provide the best overall sensitivity factor in organic solvent.
