Advanced Functional Photochromic Wearables with Superior Durability and Stability for Sustainable Applications

Advanced Functional Materials (2024)

Meng Zhu Bingang Xu Tiandi Chen Junze Zhang Weiwei Sun

Abstract The rewritable wearables based on photochromism have emerged as attractive candidates in inkless printing applications. Among various photochromic materials, polyoxometalates have great potential for rewritable wearables, with major advantages in fast response upon UV irradiation, long‐term photochemical stability, and excellent fatigue resistance. However, the development of rewritable wearables based on polyoxometalates is limited by low combining fastness, weak stability, and poor scalability. Here, a scalable strategy is reported to fabricate an ideal rewritable wearable based on fundamental charge balance mechanism. The pristine cotton substrate is grafted by cationic polymer brushes to incorporate photochromic phosphomolybdic acid (PMoA) anions through electrostatic attraction, and then the cationic surfactants with alkyl chains are introduced to encapsulate the PMoA anions to achieve charge balance subsequently. The resultant rewritable wearables display the long‐awaited properties, such as high color contrast, favorable reversibility (>10 cycles), long color retention (>15 days) and high stability against detergent and sweat (pH 6.5–8.0) during repeated washing (50 cycles) and wearing. As a demonstration, a rewritable T‐shirt is scalably fabricated, and excellent antibacterial activity and biocompatibility are demonstrated as well, which is expected to be a sustainable solution for regular fabric printing in household products and public display.

Chelating Coordination Regulated Photochromic Electrospun Nanofibers for Waterproof and Long-Color-Retention Rewritable Wearables

ACS Applied Materials & Interfaces (2024)

Tiandi Chen Bingang Xu Jing Han Meng Zhu Junze Zhang

Photochromic materials with rapid color-switching, long color retention times, and rewritability are crucial for meeting the requirements of future rewritable ink-free media. However, these requirements are challenging to satisfy simultaneously due to the inherent constraints among these features. Herein, a novel photochromic nanofiber nonwoven fabric was designed and constructed based on a conjugated organic–inorganic hybrid structure through electrospinning and hot-pressing techniques. The as-prepared fabric can change color in merely 5 s under UV irradiation and can reach saturation within 2 min. In addition, upon the introduction of a potent metal chelator, its color retention time exceeds 14 days under ambient conditions, significantly longer than that of most rewritable materials recently reported (several hours to 5 days). Moreover, the fabric exhibits high writing resolution and can be photoprinted and heat-erased for over 100 cycles while still retaining 96% of its initial reflectivity. Hydrophobic thermoplastic polyurethane provides the fabric with excellent waterproof and antifouling properties, thus preventing the composite from swelling or collecting graffiti due to moisture or dust. This work exploits a competitive approach for designing flexible, rewritable, and superior functional wearables with practical applications.

Algebraic approach and exact solutions of superintegrable systems in 2D Darboux spaces

arXiv (Cornell University) (2023)

Ian Marquette Junze Zhang Yao-Zhong Zhang

Superintegrable systems in 2D Darboux spaces were classified and it was found that there exist 12 distinct classes of superintegrable systems with quadratic integrals of motion (and quadratic symmetry algebras generated by the integrals) in the Darboux spaces. In this paper, we obtain exact solutions via purely algebraic means for the energies of all the 12 existing classes of superintegrable systems in four different 2D Darboux spaces. This is achieved by constructing the deformed oscillator realization and finite-dimensional irreducible representation of the underlying quadratic symmetry algebra generated by quadratic integrals respectively for each of the 12 superintegrable systems. We also introduce generic cubic and quintic algebras, generated respectively by linear and quadratic integrals and linear and cubic integrals, and obtain their Casimir operators and deformed oscillator realizations. As examples of applications, we present three classes of new superintegrable systems with cubic symmetry algebras in 2D Darboux spaces.

Identification of oxidative phosphorylation-related genes in moyamoya disease by combining bulk RNA-sequencing analysis and machine learning

Frontiers in Genetics (2024)

Zhiguang Han Junze Zhang Yutao Su Zhenyu Zhou Yanru Wang

Introduction: Moyamoya disease (MMD) is a chronic cerebrovascular disease that can lead to ischemia and hemorrhagic stroke. The relationship between oxidative phosphorylation (OXPHOS) and MMD pathogenesis remains unknown. Methods: The gene expression data of 60 participants were acquired from three Gene Expression Omnibus (GEO) datasets, including 36 and 24 in the MMD and control groups. Differentially expressed genes (DEGs) between MMD patients MMD and control groups were identified. Machine learning was used to select the key OXPHOS-related genes associated with MMD from the intersection of DEGs and OXPHOS-related gene sets. Gene ontology (GO), Kyoto encyclopedia of genes and genomes (KEGG), gene set enrichment analysis (GSEA), Immune infiltration and microenvironments analysis were used to analyze the function of key genes. Machine learning selected four key OXPHOS-related genes associated with MMD: CSK , NARS2 , PTPN6 and SMAD2 ( PTPN6 was upregulated and the other three were downregulated). Results: Functional enrichment analysis showed that these genes were mainly enriched in the Notch signaling pathway, GAP junction, and RNA degradation, which are related to several biological processes, including angiogenesis, proliferation of vascular smooth muscle and endothelial cells, and cytoskeleton regulation. Immune analysis revealed immune infiltration and microenvironment in these MMD samples and their relationships with four key OXPHOS-related genes. APC co-inhibition ( p = 0.032), HLA ( p = 0.001), MHC I ( p = 0.013), T cellco- inhibition ( p = 0.032) and Type I IFN responses ( p < 0.001) were significantly higher in the MMD groups than those in the control groups. The CSK positively correlated with APC co-inhibition and T cell-co-inhibition. The NARS2 negatively correlated with Type I IFN response. The SMAD2 negatively correlated with APC co-inhibition and Type I IFN response. The PTPN6 positively correlated with HLA, MHC I and Type I IFN responses. Discussion: This study provides a comprehensive understanding of the role of OXPHOS in MMD and will contribute to the development of new treatment methods and exploration of MMD pathogenesis.

Spatio-temporal changes in the causal interactions among Sustainable Development Goals in China

Humanities and Social Sciences Communications (2023)

Min Cao Min Chen Junze Zhang Prajal Pradhan Huadong Guo

Abstract Extensive efforts have been dedicated to deciphering the interactions associated with Sustainable Development Goals (SDGs). However, these developments are hampered by a lack of efficient strategies to avoid beneficial synergies being offset by harmful trade-offs. To fill these gaps, we used causal diagnosis and network analysis methods to construct 1302 directed networks of SDGs for 31 provinces in China from 2000 to 2020. We observed a dramatic offsetting effect of SDG synergies and trade-offs in China from 2000 to 2020, with approximately 27% of trade-off indicator pairs turning into synergies and about 25% of the synergy indicator pairs turning into trade-offs. However, our findings suggested that prioritising the progress of high-frequency indicators in virtuous cycles could multiply the positive systemic effects of the SDGs. Moreover, controlling the transition from passive to active in the trade-off network of SDGs remains a challenge in advancing the SDGs holistically.

Avoiding the “Great Filter”: An assessment of climate change solutions and combinations for effective implementation

Frontiers in Climate (2022)

Junze Zhang Kerry K. Zhang Mary Zhang Jonathan H. Jiang Philip E. Rosen

Global climate temperatures have unmistakably risen, and naturally occurring climate variability alone cannot account for this trend. Human activities are estimated to have caused about 1°C of global warming above the preindustrial baseline, and if left unchecked, it will continue to drastically damage the Earth and its inhabitants. Attempts toward alleviating the effects of global warming have often been at odds and remain divided among a multitude of strategies, reducing the overall effectiveness of these efforts. It is evident that collaborative action is required for avoiding the most severe consequences of climate change. This article evaluates the main strategies (industrial/energy, political, economic, agricultural, atmospheric, geological, coastal, and social) toward both mitigating and adapting to climate change. Also, it provides an optimal combination of seven solutions that can be implemented simultaneously, working in tandem to limit and otherwise accommodate the harmful effects of climate change. Previous legislation and deployment techniques are also discussed as guides for future endeavors.

A facile scalable conductive graphene-coated Calotropis gigantea yarn

Cellulose (2022)

Junze Zhang Jing Liu Zeyu Zhao Di Huang Chao Chen

Abstract Graphene-functionalized fibers have attracted substantial attention due to their potential applications in flexible wearable electronics. However, these conventional conductive materials face difficulties in mass production, which limits their large-scale fabrication. In this paper, we report a graphene-coated Calotropis gigantea yarn by pad dyeing with graphene oxide and a reduction process, which endows it with high conductivity, outstanding conducting stability, and scale production capacity. By optimizing the dyeing parameters, the modified yarns display a high electrical conductivity of 6.9 S/m. Range analysis results indicate that the electrical conductivity of the graphene-coated yarns exhibits a strong dependence on the concentration of graphene oxide and pad dyeing cycles. The hydrogen bonding between the fiber and graphene during the dyeing process renders the functionalized yarns stable conductivity to washing and bending. Based on the simple fabrication process and fascinating performance, the graphene-coated yarn show great potential in facile scale production of conductive yarns.

Achieving High Thermoelectric Performance in Bi₂(Te, Se)₃ Thin Film with (00l)-Oriented by Incorporating Tellurization and Selenization Processes

ACS Applied Materials & Interfaces (2024)

Zhuanghao Zheng Ning Chen Zilong Zhang Junze Zhang Dong Yang

Flexible thermoelectric (TE) generators have received great attention as a sustainable and reliable option to convert heat from the human body and other ambient sources into electricity. This study provides a synthesis route that involves thermally induced diffusion to introduce Te and Se into Bi, fabricating an n-type Bi–Te–Se flexible thin film on a flexible substrate. This specific synthesis alters the crystal orientation (00l) of the thin film, improving in-plane electrical transportation and optimizing carrier concentration. Consequently, BixTeySe0.42 enhanced both the Seebeck coefficient and electrical conductivity, achieving a power factor of 17.1 μW cm–1 K–2 at room temperature. The TE device assembled with p-type Sb2Te3 exhibited exceptional flexibility with only a 26.2% change in resistance after 1000 times of bending at a radius of about 6 mm. The resistance change was further reduced to 7.5% after the application of a vinyl laurate coating. The fabricated TE device generated an ultrahigh output power of 792 nW with a temperature difference of 30 K.
