The Effect of Size Distribution on the Geochemistry and Mineralogy of Tropical River Sediments and Its Implications regarding Chemical Weathering and Fractionation of Alkali Elements

open access: yesLithosphere, 2022
The mineralogical and geochemical compositions of the sediments deposited by rivers have been used extensively to evaluate past chemical weathering and the physical erosion history of drainage basins at different time scales.

An Adaptive Inhibitory WSe2 Transistor for Retinomorphic In‐Sensor Image Processing

open access: yesAdvanced Functional Materials, EarlyView.
Conventional retinomorphic devices typically require deliberate gate‐bias tuning for each illumination condition. In this paper, we demonstrate an adaptive inhibitory WSe2 transistor that uses photo‐induced regime shift between the subthreshold and accumulation modes to achieve decision‐free, intensity‐adaptive image processing within a single pixel ...

Relationship between Chemical Weathering Indices and Shear Strength of Highly and Completely Weathered Granite in South Korea

open access: yesApplied Sciences, 2021
In South Korea, weathered granite is widely distributed and has been used as a bearing stratum for various structures. Therefore, it is important to determine the shear strength of the weathered granite.

The Showalter index and associated weather

open access: yesAustralian Meteorological Magazine, 1960
At Queensland radio–sonde stations for the period September 1957 to May 1958, stability indices for 800 aerological soundings indicative of the air mass types over the State were compared with subsequent weather, and classified into air mass and frontal types.

Correlated Charge Transport in an Organic Coulomb Glass

open access: yesAdvanced Materials, EarlyView.
ABSTRACT Advances in the development of organic field‐effect transistors (OFETs), electrically gated organic semiconductors (EGOFETs), and organic electrochemical transistors (OECTs) allow for the operation of these devices at very high charge‐carrier densities, where Coulomb interactions between carriers can be expected to become significant.

Petrography and geochemical decomposition parameters of crystalline rocks; Demirköy intrusive body (DIB), NW Turkey

open access: yesBulletin of the Mineral Research and Exploration, 2021
The crystalline rocks represent the most weathering rock groups due to their textural and mineralogical decomposition. This study, focused on the petrographic properties and geochemical variation of the altered rocks from Demirköy Intrusive Body (DIB ...

Electrochromic Adaptive Solar Heater and Sub‐Ambient Passive Daytime Radiative Cooler

open access: yesAdvanced Materials, EarlyView.
An electrochromic Cu–Bi nanocluster device dynamically switches between solar heating and daytime sub‐ambient radiative cooling without mechanical motion. Defect‐activated graphene, minimized electrolyte loss, and pulse‐assisted reversible electrodeposition enable opposite solar and mid‐infrared modulation in one opaque platform, establishing a design ...

The effect of tropical weathering on the strength and anisotropy index of weathered shale [PDF]

open access: yes, 2014
Sedimentary rocks to be specific shale as it is the rock being studied can be adversely affected by weathering action; hence the alteration of its engineering properties is incontestable.

Soft Yet Tough Tanglemers Through Rapid Photopolymerization for DLP 3D Printing

open access: yesAdvanced Materials, EarlyView.
Soft yet tough tanglemers are produced through low‐initiator free radical photopolymerization and translated to DLP 3D printing. Systematic control over light intensity, initiator loading, and crosslink density reveals processing windows that balance printability, elasticity, toughness, and feature fidelity. ABSTRACT Additive manufacturing of compliant
