Curved Nanographene–Graphite Hybrid Anodes with Sequential Li+ Insertion for Fast‐Charging and Long‐Life Li‐Ion Batteries

Advanced Functional Materials, EarlyView.
A hybrid anode composed of Cl‐functionalized curved nanographene and graphite enables ultra‐fast charging and long cycle life through an engineered morphology and sequential Li+ insertion. It delivers 100 mAh g−1 at 5 C with 70% capacity retention after 1000 cycles and maintains stable performance over 2000 cycles in pouch cells, providing a practical ...

Ultrahigh‐Yield, Multifunctional, and High‐Performance Organic Memory for Seamless In‐Sensor Computing Operation

Advanced Functional Materials, EarlyView.
Molecular engineering of a nonconjugated radical polymer enables a significant enhancement of the glass transition temperature. The amorphous nature and tunability of the polymer, arising from its nonconjugated backbone, facilitates the fabrication of organic memristive devices with an exceptionally high yield (>95%), as well as substantial ...

Gas turbine engine with recirculating bleed [PDF]

, 1978
Carbon monoxide and unburned hydrocarbon emissions in a gas turbine engine are reduced by bleeding hot air from the engine cycle and introducing it back into the engine upstream of the bleed location and upstream of the combustor inlet. As this hot inlet

Comparing carbon sequestration in an oil reservoir to sequestration in a brine formation-field study [PDF]

, 2008
Geologic sequestration of CO2 in an oil reservoir is generally considered a different class than sequestration in formations which contain only brine. In this paper, the significance and validity of this conceptualization is examined by comparing the ...

Wafer‐Scale Synthesis of Mithrene and its Application in UV Photodetectors

Advanced Functional Materials, EarlyView.
A controlled tarnishing step on the silver surface precedes the solid‐vapor‐phase chemical transformation into silver phenylselenolate thin films. The approach yields crystals exceeding 1 µm with improved in‐plane orientation. Integration on graphene phototransistors demonstrates high photoresponsivity, positioning mithrene as a promising material for ...
