Vapor phase polymerization (VPP) of conducting polymers can provide highly conductive homogenous thin films but was so far reported only for a limited number of materials. Here, we report VPP deposition of the low bandgap conducting polymer poly(thieno[3,4-b]thiophene):tosylate (pT34bT:Tos) and propose an application for dynamic structural coloration. Optimized films show high electrical conductivity of around 750 S cm-1, manifested optically as wide infrared absorption extending beyond 2000 nm. Electrochemical reduction reveals a neutral low bandgap peak around 1030 nm, making pT34bT comparably transparent also in its neutral state as opposed to other common conducting polymers. Moreover, the VPP process allows to spatially control the polymer properties and thickness via a UV exposure step before polymerization. We exploit this technique to create structurally colored images using the polymer as cavity spacer layer, locally varying its thickness and optical properties. We finally demonstrate dynamic tunability of structural colors based on the application of different potentials in an electrochemical cell.","PeriodicalId":84,"journal":{"name":"Journal of Materials Chemistry C","volume":" ","pages":""},"PeriodicalIF":5.7,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11898598/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143646745","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, this work focuses on developing sustainable, flexible, and highly sensitive cellulose-based humidity sensors. To achieve this goal, a Taguchi design of experiments was suggested to optimize four key ink formulation parameters: carbon black (CB) fillers, cellulose nanofibers (CNF), polyvinyl pyrrolidone (PVP) binders, and glycerol plasticizers. The resulting formulations were subjected to material, electrical resistance, adhesion, water contact angle, and hygroresistive characterization. The results detail how the factors of interest influence the electrical response of the sensors, their sensitivity, and ink adhesion to the substrate. Moreover, increasing the CNF, glycerol, and PVP while reducing CB enhances sensitivity and ink performance. Optimized sensors demonstrated high responsiveness between 20% and 90% relative humidity, with an exponential growth rate of 9.6–10.0% RH−1. The optimized sensors were also assessed regarding their repeatability across 10 cycles, stability to bending, and insensitivity to temperature variation. These findings highlight the role of formulation interactions in sensor performance and demonstrate the potential of eco-friendly and highly sensitive humidity sensors for next-generation flexible electronics.","PeriodicalId":84,"journal":{"name":"Journal of Materials Chemistry C","volume":" 13","pages":" 6508-6526"},"PeriodicalIF":5.7,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143716570","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We exploited the nonlinear dynamics of protein macromolecules and ions in the albumen to perform high-dimensional mappings of input data. Our albumen-based reservoir achieved classification accuracy comparable to conventional machine learning methods on benchmark datasets while consuming over 5000 times less energy during training. Notably, the reservoir exhibited short-term plasticity analogous to biological synapses, with conductance spikes and fading memory. This bio-inspired computing paradigm not only offered a sustainable alternative to traditional architectures but also provided insights into the information-processing capabilities of biological systems.

However, obtaining both a high color rendering index (Ra) and high luminous efficiency (LE) concurrently poses a great challenge for the development of laser-driven white lighting. Herein, a novel tricolor phosphor-in-glass film (PiGF) is designed and fabricated via a facile low-temperature co-sintering strategy. ZnO–Li2O–SiO2 (ZLS) glass along with Y3Al5O12:Ce3+ (YAG), CaAlSiN3:Eu2+ (CASN), and Lu3(Al, Ga)5O12:Ce3+ (LuAGG) phosphors was coated onto sapphire substrates via the blade-coating method and then subjected to low-temperature co-firing, fabricating composite phosphor-in-glass film (PiGF) samples for full-spectrum laser-driven white lighting. High LE and Ra were achieved by optimizing the glass layer thickness, phosphor concentrations, phosphor ratio, film structure, and sintering process. The YAG-PiGF achieves a high luminous flux (LF) of 1129 lm and a Ra of 62. Further addition of CASN and LuAGG phosphors fills the color gaps, resulting in a composite PiGF with a high Ra of 92 and a LE of 212 lm W−1. The excellent balance between Ra and LE makes this color converter highly promising for high-quality laser lighting applications.","PeriodicalId":84,"journal":{"name":"Journal of Materials Chemistry C","volume":" 14","pages":" 7402-7410"},"PeriodicalIF":5.7,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143769639","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, a NIR phosphor, Lu3Ga5−2xMgxGexO12 (LGMG):0.05Cr3+, with an emission center wavelength of 726 nm was investigated. After employing the co-substitution strategy, it was found that the strength of the crystal field in the vicinity of Cr3+ gradually weakened, resulting in broadening of the emission spectrum to the full width at half maximum (FWHM) of 155 nm. Notably, the developed phosphors have high IQE values and relatively better thermal stability. After optimization, the absorption spectrum of the obtained broadband near-infrared luminescent phosphor showed a high degree of matching with the absorption spectrum of the phytochrome PFR. NIR pc-LEDs devices were successfully prepared by combining the LGMG:Cr3+ phosphor with commercialized blue LED chips.

This step is crucial for optimizing the performance of the photocatalytic hydrogen production.

The optimized composite ZnCdS/CoMn2O4 demonstrated a 4.76-fold increase in hydrogen production compared to ZnCdS alone and exhibited excellent catalytic activity. Further characterization using techniques, like in situ XPS and DFT calculations, revealed that the p–n type heterojunction effectively promoted the separation of photogenerated electron–hole pairs, a key step for efficient hydrogen production. Furthermore, the enhanced redox capacity of the composite photocatalyst was confirmed by electron paramagnetic resonance analysis. The broadened light absorption range of the composite photocatalyst was also demonstrated, providing an ample number of active sites.

We present a simple and effective method to prepare functional silica hybrid particles with tunable properties through the co-condensation of tetraethoxysilane and an organoalkoxide precursor using a modified Stöber process. Three organoalkoxide precursors have been studied: (3-mercaptopropyl)triethoxysilane, (3-cyanopropyl)triethoxysilane, and (3-aminopropyl)triethoxysilane. All three investigated systems produce functional silica hybrid particles, as confirmed by various characterization techniques. Scanning transmission electron microscopy and nitrogen sorption analysis demonstrated that features such as the microstructure could be tailored by the careful selection of the second precursor. A drastic increase in the specific surface area can be obtained with 3cyanopropyltriethoxysilane: 270 m2 g−1 compared to 17 m2 g−1 in the unfunctionalized silica particles. Other important characteristics such as the degree of condensation and surface charge can also be influenced by precursor choice. The enhanced reactivity of 3-aminopropyltriethoxysilane yields a higher degree of particle functionalization. Nanoscale chemical mapping has been performed using energy-dispersive Xray spectroscopy and Auger spectroscopy. Homogeneous distribution of the functionalities within the hybrid particles occurs. The present work gives tools to easily tailor functional silica particles, thus providing simple ways to tune their properties to meet a wide range of applications.","PeriodicalId":84,"journal":{"name":"Journal of Materials Chemistry C","volume":" 14","pages":" 7318-7326"},"PeriodicalIF":5.7,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11881562/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143584027","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
