A Retinomorphic Graphene Transistor Implementing Direction‐ and Velocity‐Selective Computation for In‐Sensor Image Stabilization

Small, EarlyView.
A multi‐gated ion‐gel graphene transistor architecture emulates spatiotemporal dendritic filtering inspired by biological direction‐selective retinal circuits. Leveraging distributed resistance‐capacitive ionic relaxation delays under combined excitation‐inhibition pulse routines, the solid‐state device exhibits programmable direction‐selective index ...

Sequential Reduction of Chromite Pellets Using Hydrogen and Silicon Carbide for Carbon Emission Abatement During Ferrochrome Production

steel research international, EarlyView.
H2 prereduction selectively metallizes Fe in UG2 chromite pellets at 1100°C, while silicon carbide becomes active at 1300°C to convert remaining Cr2O3 to carbides and promote Cr metallization. By separating the roles of H2 and SiC, the sequential route reaches up to 65.7% Cr metallization and suppresses in‐furnace CO generation by ≈75% versus ...

Polyaniline as a dual flame retardant and electrostatic dissipative additive in polyethylene nanocomposites

Journal of Vinyl and Additive Technology, Volume 31, Issue 2, Page 339-355, March 2025.
Effecft of co‐doping polyaniline with phosphoric acid and phytic acid on the heat release rate of polyethylene. Abstract Polyolefins, such as polyethylene (PE), are highly flammable and electrically insulative, limiting their applicability. The study explored the flame‐retardancy and electrical conductivity of PE/polyaniline (PE/PANI) nanocomposites ...

From mystery to modulation: the structural story of Rb2[Si2O5]

Acta Crystallographica Section B, EarlyView.
The crystal structure of Rb2[Si2O5] has been solved and refined as an incommensurately modulated phase. Each [SiO4] tetrahedron of the phyllosilicate adopts one of two distinct orientations, and the positions of their constituent silicon and oxygen atoms are modeled using a combination of crenel and harmonic positional modulation functions.The crystal ...

Lost in the Language: Data Breaches and the Strategic Fog of Risk Disclosures

Accounting &Finance, EarlyView.
ABSTRACT This study examines whether firms strategically adjust the readability of Item 1A (“Risk Factors”) disclosures following data breaches. Using U.S. firm‐year observations from 2006 to 2023, we find that data breaches are associated with a significant decline in Item 1A readability.

Marketing features of derived intoxicating cannabinoid product brands on Instagram: A content analysis

Addiction, EarlyView.
Abstract Background and aims Use of derived intoxicating cannabinoid products (DICPs) has grown in the United States (US), as have associated poisonings, emergency department visits and psychotic episodes. Brand marketing on social media, a largely underregulated marketing channel, may be contributing to this growth.

Usher syndrome‐related visual impairment in Finland: A 35‐year nationwide register‐based study (1985–2019)

Acta Ophthalmologica, EarlyView.
Abstract Purpose To investigate visual impairment (VI) associated with Usher syndrome (USH), a syndromic form of retinitis pigmentosa. Methods This register‐based study used data from the Register of the Finnish Federation for Visual Impairment for persons registered with USH‐related VI from 1985 to 2019.

Comparative Analysis of the Effect Dual Spark Ignition and Single Spark Ignition on Performance and Exhaust Emissions in Bioethanol-Fueled Engines

Journal of Mechanical Engineering Science and Technology
Bioethanol is an alternative fuel that has a high octane value of around 100 to 110, making it difficult to be applied to spark ignition engines directly.
