Regenerating High-Performance Lithium Iron Phosphate through Establishing a Stable Structure via Designing a Reaction Path with Easy-Transformed Intermediates

Abstract Regenerating lithium iron phosphate (LFP) from recovered lithium carbonate and iron phosphate by conventional hydrometallurgy process is challenged by high wastewater treatment cost and the unsatisfying performance of regenerated LFPs. Herein, a nanoscale LFP with enhanc...

Investigation on NH3‑SCR performance and low N2O formation mechanism over MIL‑100(FeMn) catalyst

Fe-based metal–organic frameworks (Fe-MOFs) have attracted extensive attention in the field of NH 3 -SCR denitrification due to their environmental friendliness and tunable redox properties. In this work, the catalytic performance of bimetallic MIL-100(FeMn) catalysts was systema...

One-Pot Tandem Annulation of N -(2-Alkynylaryl)- N -sulfonylcyanamides with Water for the Synthesis of 2-Amino-3-carbonylindoles

Abstract A metal-free, one-pot tandem annulation of N-(2-alkynylaryl)-N-sulfonylcyanamides with water has been developed for synthesizing 2-amino-3-carbonylindoles. The reaction proceeds via isolable N,O-BF2-chelated intermediates, which undergo Et3N-mediated ring opening. Water...

Tuning Second-Sphere Amine Basicity to Modulate Hydride Intermediates and Selectivity in Molecular Manganese Bipyridine CO2 Electroreduction

Abstract Manganese bipyridine tricarbonyl complexes represent a prominent class of molecular electrocatalysts for efficient and selective CO2-to-CO conversion. Recent efforts have sought to redirect product selectivity toward HCOOH by incorporating second-sphere amine proton rela...

A Strain Compatibility Criterion for Three-Dimensional Chip Curling

The final geometry of a three-dimensional chip is commonly described by a combination of geometric parameters, including curl radius, pitch, and axis orientation. However, parameter combinations that are mathematically admissible do not necessarily correspond to material deformat...

Electrical insulation enhancement of the Al 2 O 3 composite films at high temperature by oxygen vacancy suppression

Abstract The electrical insulation film is critical for the reliable operation of Ultra-high temperature thin-film sensors (UTTSs) at elevated temperatures. However, the resistance of the insulation film easily decline at high temperatures due to the formation of the oxygen vacan...

Photopolymerization Kinetics and Improved Performances of Polyacrylate-Type Semi-interpenetrating Solid Polymer Electrolytes

Abstract Crosslinking solid polymer electrolytes (SPEs) are expected to expedite the extensive application of lithium metal batteries (LMBs) by enabling appropriate ionic conductivity and good compatibility with the cathode. However, researchers tend to focus more on the performa...

A Multifunctional Molecular Bridge at the Bottom Interface of Perovskite Solar Cells for Crystallization Regulation and Efficient Carrier Extraction

ABSTRACT Perovskite solar cells (PSCs) have attracted widespread attention from researchers worldwide and experienced rapid development in recent years. The bottom interface plays a crucial role in charge transfer and collection, and its status significantly affect the perovskite...

Cu‐Mo Plasmonic Coupling Generates Enhanced Local Electromagnetic Fields in Co 0.5 Cu 0.5 /Mo Heterostructures for Photocatalytic Ammonia Borane Hydrolysis

ABSTRACT Plasmon‐mediated catalysis provides a promising route for enhancing photocatalytic hydrogen generation from ammonia borane (NH 3 BH 3 ), yet the reaction rate remains limited by insufficient charge generation and separation. Herein, we address this limitation by developi...

Constrained endurance in long-term family caregiving: Rethinking resilience through nursing ethics

Resilience is an established concept in family-caregiver research, where it is used to describe how caregivers maintain functioning and adapt to sustained adversity. In long-term family care for older adults with disabilities, however, resilience is ethically ambiguous. Continued...

Stability, cross‐resistance, mechanisms and inheritance of laboratory‐selected resistance to chlorfenapyr in Plutella xylostella

Abstract BACKGROUND The diamondback moth (DBM), Plutella xylostella (Linnaeus), a globally destructive pest of cruciferous crops, has developed resistance to numerous insecticides, including chlorfenapyr. To elucidate the resistance characteristics of DBM to chlorfenapyr, a resis...

Passive radiative cooling for vertical building facades: From fundamental constraints to practical strategies

Rising space-cooling demand driven by urbanisation and climate change has increased interest in passive alternatives to air conditioning. Passive radiative cooling (PRC) dissipates heat through the atmospheric window (8–13 μm) without energy input. However, research has largely f...

Dynamic Diels–Alder-Crosslinked Zwitterionic Polyurethane Coatings with Self-Healing, Antibacterial, and Antifouling Properties

Coatings used in marine and humid environments are simultaneously exposed to biofouling and mechanical damage, which progressively compromise their interfacial functionality and service stability. In this study, polyurethane resins bearing terminal maleimide groups and sulfobetai...

A computable transcendental number without eventually greedy best Egyptian underapproximations

We give a deterministic rational recursion defining a specific computable transcendental number whose best Egyptian underapproximations do not form an eventually nested chain. The construction first finds, inside any rational interval in (0,1), a smaller interval on which a presc...

Oncolytic Virus-like Nanoparticle Targets the Golgi Apparatus via Sphingomyelin

Abstract The Golgi apparatus (GA) has emerged as a promising target for cancer therapy. Commonly, therapeutics are guided to the GA by recognizing specific receptors on the GA membrane. However, the low and heterogeneous expression of these receptors often results in suboptimal t...

EEG-UDAF: A novel unsupervised domain adaptation framework leveraging dual-view frequency and spatio-temporal features for EEG-based emotion recognition

Currently, machine learning technology has been widely used in electroencephalogram (EEG) automatic emotion recognition tasks. However, the non-stationarity, individual differences, and high annotation costs in EEG signals seriously affect the generalization ability of the model....

Family socioeconomic resources, family differentiation, and short-term change in health literacy among Chinese university students: a three-wave longitudinal study

Family resources and relationships may shape the opportunities through which students acquire and use health information. Longitudinal evidence is needed to distinguish their associations with initial health literacy from those with subsequent change. This three-wave study follow...

Capturing Ag6 Inner-Core Contraction in Inorganic-Template-Stabilized Ag78 Nanoclusters

Abstract Resolving how subangstrom changes in a metal core affect electronic structure and photophysical properties in high-nuclearity silver nanoclusters (NCs) remains challenging, as inner-core variations are often coupled with changes in outer metal shells, surface coordinatio...
