Surface engineering on particulate photocatalysts can significantly improve the performance of photocatalytic H2O2 production by optimizing light absorption, surface charge separation, and reaction pathways. To provide a comprehensive and systematic illustration of this topic, various surface engineering strategies are classified and elaborated in this review, which are mainly included in the following two aspects. The first one involves surface modification relating to crystal facets, surface vacancies, and surface functional groups. The second one focuses on surface composite strategies, including combination with metals, semiconductors, carbon nanomaterials, polyoxometalates or their derivatives, and organic compounds. Finally, the challenges and prospects in the surface engineering strategies for particulate photocatalysts for promoting photocatalytic H2O2 production are analyzed and discussed.","PeriodicalId":87,"journal":{"name":"Materials Horizons","volume":" ","pages":""},"PeriodicalIF":12.2,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144598953","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}

Expansion microscopy (ExM) permits nanoscale imaging of biomolecules on a conventional microscope by physically expanding biological specimens embedded in a stretchable hydrogel. However, achieving simultaneous super-resolution co-imaging of proteins and nucleic acids on ExM has remained a general challenge. Here, we present photoclick dual anchoring expansion microscopy (Phan-ExM), which employs an unorthodox anchoring reagent, N-(3-methacrylamidopropyl)-3-(2-methyl-1H-pyrrol-1-yl)-2H-tetrazole-2-carboxamide (MAP-mPyTC), for the rapid and concurrent retention of proteins and nucleic acids within the ExM gel matrix through photoclick chemistry. We demonstrated that MAP-mPyTC could anchor both protein and mRNA biomolecules within 10 min, significantly reducing the time compared to typical ExM techniques, which usually take from several hours to overnight. Moreover, we showed that Phan-ExM significantly enhanced the fluorescence intensity of protein and RNA spots compared to previous methods. With Phan-ExM, we achieved high-resolution co-imaging of multiplex proteins and nucleic acids on a single specimen at ∼85 nm resolution. We revealed that paclitaxel and colchicine treatment significantly disrupted mitochondrial dynamics in BALB/c3T3 cells, with an associated aggregation of ACTB mRNA observed at sites of mitochondrial damage. Phan-ExM is a platform technique that enables super-resolution co-localization of nucleic acids and proteins on the same specimen using a conventional microscope.","PeriodicalId":87,"journal":{"name":"Materials Horizons","volume":" ","pages":""},"PeriodicalIF":12.2,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144582631","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 address this challenge using a machine-learned interatomic potential trained on ab initio data across the PbTe1-xSex alloy series. Molecular dynamics simulations with the trained machine-learned interatomic potential reproduce experimental lattice thermal conductivities and density-functional theory phonon dispersions while enabling frequency-resolved analysis of heat transport from 300 to 800 K. We find a narrow window near 1.7-2.0 THz dominates heat transport across all compositions, where heat is primarily carried by mixed longitudinal acoustic and optical modes. Alloying dramatically reduces spectral diffusivity near 2 THz leading to the deterioration of thermal conductivity. For the parent compounds both the spectral diffusivity and overall thermal conductivity decrease at elevated temperatures. However, the thermal degradation is weaker for the mid-range composition (x = 0.5) due to the greater thermal occupation of vibrational modes and increased heat capacity. Alchemical simulations show that force-constant disorder, not mass contrast, plays the dominant role in this suppression. These results highlight the microscopic mechanisms underlying thermal transport breakdown in alloys and demonstrate how machine-learned interatomic potentials now offer a tractable path toward predictive, physics-rich thermal transport modeling in complex disordered solids.","PeriodicalId":87,"journal":{"name":"Materials Horizons","volume":" ","pages":""},"PeriodicalIF":12.2,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144582615","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}

While unconventional transistors have broadened application possibilities in recent decades, further innovation remains essential. Here an organic dual-channel transistor (DCT) is proposed. This device features a bottom channel formed through vertical phase separation between an insulating polymer and organic semiconductors, coupled with a distinct top semiconductor channel. By engineering the differences in channel thickness, carrier mobility, and energy levels, we achieved tunable charge accumulation and transport dynamics. The prepared organic dual-channel transistors display unique device characteristics: ID ∝ V0G when VD < VG - VT and ID ∝ V1G when VD ≥ VG - VT, which are significantly different from those of conventional devices. Subsequently, we demonstrate applications in signal modulation circuits capable of peak-to-valley ratio tuning and signal erasure. The characteristics of DCTs have four modulation effects on signals, whereas conventional devices can only achieve two. The enhanced functional density endows DCTs with enormous application potential in high-performance chips and related fields. Additionally, DCTs exhibit nonvolatility, allowing the device's states to be altered through programming, thus easily switching between modulation effects (reconfigurable operation). Finally, the anti-counterfeiting implementations highlight their practical versatility. This work provides ideas for the development of multifunctional devices and their application scenarios.","PeriodicalId":87,"journal":{"name":"Materials Horizons","volume":" ","pages":""},"PeriodicalIF":12.2,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144582629","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}

A 24 × 24 crossbar array was fabricated using non-filamentary HT-RRAM, and quantized and pruned weights were transferred to the array. The compact model of HT-RRAM was used as a synaptic device to simulate a crossbar array model of the same scales the fabricated array, and the same network lightweight techniques were applied in the simulation. Both the crossbar array and the array model successfully transferred over 94% of the weights within an error margin of 2 nS, and the SNN inference results over 25 time steps showed highly consistent output currents. With this reliable array model, power consumption during MNIST inference was estimated for arrays with lightweight techniques applied. Based on our experimental results, the power consumption of image inference operations is predicted to be 243 nW with weight quantization only and 222 nW with weight quantization and pruning, across 10 classes.

Herein, an injectable 3D-bioprinted scaffold encapsulated with two-phase emulsion bioink-engineered mesenchymal stromal cells is proposed, which can serve as a novel versatile platform for efficient stem cell delivery in minimally invasive approaches. The two-phase emulsion bioinks could spontaneously undergo a phase separation process in an aqueous environment to form hierarchically porous structures (macropore size of 1 mm and micropore size of 100-200 µm), which not only facilitated the proliferation and spreading of the encapsulated cells but also endowed the bioprinted scaffolds with shape memory properties for in situ injection. More importantly, the interconnected macro-microporous structures of the 3D extracellular matrix (ECM) microenvironment could provide biophysical cues to obviously enhance the paracrine functions of encapsulated cells, with the enhanced secretion of bioactive factors related to immunomodulation, angiogenesis, and neurogenesis. RNA-seq results showed that ECM-receptor interaction, focal adhesion, and cytoskeleton regulation might participate in mechanotransduction pathways, thereby enhancing cell paracrine functions. In addition, the bioprinted scaffolds could be in situ injected into skin wounds without damaging their inherent porous structure and, thus, effectively promoted neuro-vascularized skin regeneration by inducing angiogenesis, promoting neurogenesis and suppressing the inflammatory response. Taken together, we successfully prepared an injectable scaffold integrating hierarchically porous structures with the augmented paracrine activity of stem cells, which is a promising candidate for tissue regeneration and minimally invasive precision medicine.","PeriodicalId":87,"journal":{"name":"Materials Horizons","volume":" ","pages":""},"PeriodicalIF":12.2,"publicationDate":"2025-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144574505","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}

Herein, we propose that magnesium hydride (MgH2)-induced hydrogen (H2) therapy can synergistically enhance barium titanate (BTO)-mediated sonodynamic therapy (SDT) while modulating the TME to improve the efficacy of immune checkpoint inhibitors (aPD-1). Specifically, ultrasound (US) activated BTO to trigger SDT and induce immunogenic cell death (ICD), while the sustained release of H2 from MgH2 microspheres amplifies tumor cell destruction, thereby promoting immune cell recruitment to the tumor site. Meanwhile, the hydroxide ions (OH-) and magnesium ions (Mg2+) generated by MgH2 alleviate the acidic TME, reversing immune suppression and enhancing T-cell-mediated antitumor responses. In the CT26 tumor model, the synergistic combination of SDT and MgH2 therapy significantly enhances the anti-tumor efficacy of SDT compared to that of BTO alone, leading to prolonged survival of treated mice. Moreover, MgH2 upregulates PD-1 expression in T cells, markedly improving the sensitivity of tumors to aPD-1 therapy. This strategy provides a generalizable approach for enhancing SDT, demonstrating its broad potential in anti-tumor treatment and presenting a promising avenue for overcoming resistance to immune checkpoint inhibitors.","PeriodicalId":87,"journal":{"name":"Materials Horizons","volume":" ","pages":""},"PeriodicalIF":12.2,"publicationDate":"2025-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144574506","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}
