Novel Zwitterionic Polydopamine Nanofiller‐Reinforced Hybrid Membranes With Superior Antifouling Performance for Wastewater Treatment

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work reports one‐pot synthesized novel zwitterionic polydopamine‐silica (ZSiPDA) nanofillers for fabricating PES hybrid ultrafiltration membranes with enhanced hydrophilicity, permeability, and antifouling performance. The optimized membrane achieved over 91% humic acid removal and showed strong potential for municipal wastewater treatment.

The mechanism of spontaneous corrugation on the snowy and icy roads produced by the moving vehicles in cold regions

open access: yesJournal of Infrastructure Preservation and Resilience
Traffic safety in cold regions is seriously affected by the snow and ice brought by the extreme climate. The snowy and icy road cannot provide enough friction for the safe operation of vehicles due to its smooth and uneven surface.

Structure‐Driven Thermal Insulation Through Single‐ and Double‐Shell Hollow Silica Nanospheres Via a Single‐Step Sacrificial‐Interlayer Strategy

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A single‐step sacrificial‐interlayer strategy enables precise modulation of inter‐shell spacing in hollow silica nanospheres, allowing direct comparison of thermal insulation characteristics between single‐ and double‐shell architectures. The hierarchical design amplifies phonon scattering and disrupts solid heat pathways, achieving an ultralow thermal

The Critical Role of Economies of Scale: A Techno‐Economic Assessment of Small‐ Versus Large‐Scale Biogas Upgrading in Rural Tanzania

open access: yesEnergy Science &Engineering, EarlyView.
Small‐scale biogas upgrading can improve methane quality but remains financially unattractive to individual rural households. Community‐scale implementation substantially lowers energy costs, demonstrating that economies of scale are critical to making purified biogas a viable clean‐cooking option in Tanzania.

Electrochemical Valence‐Regulated Biomimetic Nanozymes for Breast Cancer Metabolism Inhibition and Potentiated Catalytic Immunotherapy

open access: yesExploration, EarlyView.
MnOx nanozymes face low tumoricidal activity and PD‐L1‐mediated immune attenuation. Electrochemically regulated M‐MnOx with high oxidase activity was TCM‐wrapped into TMO. TMO targets tumors, triggers ICD, activates cGAS‐STING, antagonizes PD‐L1, and suppresses tumor recurrence, providing new insights for Mn‐based nanomaterials.

Optimized Copper Pretreatment Protocols for Premium Green Raisin Production via Vacuum Impregnation and Metallo‐Complex Stabilization

open access: yesFuture Postharvest and Food, EarlyView.
ABSTRACT Green raisin production is limited by rapid chlorophyll degradation during drying. This study evaluated copper metallo‐complex formation to stabilize green pigmentation in Vitis vinifera cv. Thompson Seedless grapes. Pretreatments with copper sulfate (CuSO4) pentahydrate (2%–6% w/v) were applied via dipping and vacuum impregnation (2–10 min ...

Low‐Pressure All‐Solid‐State Lithium–Sulfur Batteries: Challenges and Design Principles

open access: yesInterdisciplinary Materials, EarlyView.
Stack pressure is redefined from an effective laboratory parameter to an external compensation for intrinsic interfacial incompatibility in all‐solid‐state lithium–sulfur batteries (ASSLSBs). This work links low‐pressure degradation to chemo‐mechanical mismatch among volume evolution, interfacial chemistry, charge transport, and mechanical response ...

Ferroelectric modulated visual devices with spatial and temporal polarization‐sensitivity for information recognition and processing in visibility‐degraded environments

open access: yesInfoMat, EarlyView.
Conventional imaging systems often struggle to recognize objects accurately in challenging environments such as underwater or foggy scenes. We developed a polarization‐sensitive artificial vision device inspired by the mantis shrimp that uses advanced two‐dimensional materials and a ferroelectric layer to directly sense, process, and retain visual ...

Emergence of Paper Corrugation in Uncoated (SC) Printing Paper

open access: yes, 2005
Myllykoski Paper Oy:n PK6:n kapeiden asiakasrullien vanoittuminen on aiheuttanut tuotannonmenetyksiä. Tämän työn tavoitteena oli pyrkiä selvittämään SC-paperirullissa esiintyvän vanaisuuden syntymekanismeja ja sitä, kuinka pituusleikkurilla voitaisiin ...

Rail corrugation growth on curves - measurements, modelling and mitigation

open access: yes, 2013
The development of rail corrugation (so called rutting corrugation) on a 120 m radius curve on the metro of Stockholm Public Transport was studied by field measurements, laboratory measurements and numerical simulations.
