However, these reactions typically require organic solvents and inert atmospheres, such as argon, increasing environmental, health, and safety (EHS) concerns. Using electron-rich bulky phosphine ligands in combination with [Pd(π-cinnamyl)Cl]₂, we generate a highly active palladium catalyst capable of achieving efficient C-N bond formation in the solid state. Remarkably, while previous studies showed that the formation of this palladium-phosphine complex occurs only in protic solvents such as water or alcohols, but not in classical organic solvents, we demonstrate its generation in the absence of any solvent, as confirmed by solid-state ³¹P NMR, supporting its role as the active catalytic species.. This process enables the coupling of a broad range of aryl bromides and chlorides with amines, anilines, amides, carbamates, or ureas, delivering good to excellent yields. This mechanochemical method operates with minimal palladium loading and proceeds efficiently in air, offering a practical and sustainable alternative to traditional solution-phase reactions.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202500545"},"PeriodicalIF":7.5,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143794165","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using a thermally induced phase separation (TIPS) method with small amounts of polyamide 12 (PA12), shape-stable, non-leakage PCMs are produced in a single cooling step. The encapsulated BHD within PA12 scaffolds retains a latent heat of 111 J g-1, ensuring structural integrity and usability across 100 thermal cycles. High-BHD content (up to 95 m%) PCMs show shape stability and mechanical recyclability, making them ideal for sustainable energy applications. Thermal properties, PA12 scaffold morphology, and temperature stability are characterized, while the addition of carbon fillers demonstrated faster heat transfer and morphological control.

However, the understanding of the specific interactions between microwave and liquefaction processes remains constrained. Furthermore, it is essential to explore the advantages that promote the scale-up of MA-HTL reactors for industrial applications, particularly in light of the unique characteristics associated with microwave technology. This review aims to systematically compile and elucidate the existing research on microwave-medium interactions in liquefaction systems, highlighting the critical relationships involved in microwave field and reaction system.

In this context, the proper selection of precursors and synthetic conditions is of paramount importance when tailoring the photocatalytic features of the resulting nanomaterials. Here, we have developed a novel bottom-up methodology for the preparation of phenol-rich carbon dots (Ph-CDs) that allowed us to capitalize on the excellent photoredox properties of surface phenolate anions that can be obtained upon deprotonation of Ph-CDs. Specifically, in this study Ph-CDs were used in combination with a suitable base and an organocatalyst, namely the Schreiner thiourea (A), to drive valuable [3+2] photocycloaddition reactions between suitable cyclopropyl ketones 1 and unsaturated hydrocarbons 2. Interestingly, mechanistic studies showed the key role played by A in the transformation. In fact, this organocatalyst may not only activate the carbonyl moiety of 1, but also stabilize the formation and enhance the photocatalytic performances of phenolate anions on the nanoparticle surfaces. Remarkably, this photocatalytic transformation provides a wide variety of densely functionalized five-membered rings 3 (17 examples, up to 99% yield) under mild operative conditions. Lastly, we demonstrate that Ph-CDs could be easily recovered and reused up to three times without any significant drop in yield.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202500521"},"PeriodicalIF":7.5,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143778767","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, a two-dimensional amorphous molybdenum oxide/titanium oxide nanotubes (MoO3-x/TNTs) heterojunction with amorphous/crystalline interfaces, is designed and fabricated by supercritical CO2, with which the photocatalytic reforming of glucose for formic acid is realized in pure water. The HCOOH yields of 14.8% for glucose and 22% for glycerol are achieved in pure water at room temperature with 2 bars O2 atmosphere within 6 hours under 365 nm light with 5 mW/cm2. The photoinduced Mo6+-catalyzed ligand-to-metal charge transfer (LMCT) and the enhanced adsorption energy of glucose molecules on the MoO3-x surface in the MoO3-x/TNTs heterojunction facilitate the cleavage of C-C bonds in polyhydric alcohol skeletons, leading to the formation of HCOOH. Under light excitation, MoO3-x transfers electrons to TNTs due to defect state, synergizing with the generated •OH radicals in the system. This results in reversible cycling between Mo6+ and Mo5+, thereby ensuring catalytic persistence. Therefore, this study demonstrates a photocatalytic strategy for the sustainable production of value-added chemicals from biomass under eco-friendly conditions, using easily recyclable heterogeneous catalysts in pure water.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202500465"},"PeriodicalIF":7.5,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143770796","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, the underlying electron and molecule transport mechanisms inside the SEI are poorly understood. Here, we elucidate transport and reaction in model-type SEIs formed at different electrode potentials by combining generator-collector experiments and electrochemical impedance spectroscopy with a diffusion-reaction modeling approach. In the generator-collector experiments, we use a four-electrode-based setup to compare the electrolyte reduction current density with a redox molecule (ferrocenium Fc+) reduction current density at an SEI-covered glassy carbon electrode. We find that the current density ratio depends on the SEI formation potential as well as on the formation time. The experimental results are compared to the prediction of a transport and reaction model, which accounts for reduction reactions inside the SEI as well as in the double layer at the SEI | bulk electrolyte interface. This model predicts four distinct diffusion and reaction regimes depending on the rate constant for the molecule-electron reaction. Using this combined approach, we obtain good estimates for the transport coefficients of electrons and molecules inside the SEI.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202402468"},"PeriodicalIF":7.5,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143770802","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Organic-inorganic hybrid PSCs have reached an astounding power conversion efficiency of >26%, but unfortunately exhibit poor long-term stability, which severely impeded their commercialization. Inorganic perovskite exhibits excellent thermal stability compared to hybrid perovskite. Among inorganic perovskite, cesium lead triiodide (CsPbI3) is an ideal material for constructing tandem solar cells. However, the spontaneous transition of the black phase to a non-perovskite phase hinders their reliable application. These phase transitions are largely correlated with the unexpected strain introduced during fabrication and operation. Strain engineering is an ideal method to address this issue, which directly acts on the crystal lattice and has a straight impact on phase stability. In this review, we outline the characterization and impacts of strain in inorganic perovskite and recent breakthroughs in strain engineering.
