Linker‐Engineered Dimeric Acceptors Afford Efficient Organic Photocatalytic Hydrogen Evolution via Tailored Nanomorphology for Long‐Lived Charge Accumulation

open access: yesAdvanced Materials, EarlyView.
We developed a new series of monomeric (MY) and dimeric acceptors incorporating unfused (DY1) and fused (DY2) linkers, which establish a controlled self‐aggregation trend of MY > DY2 > DY1. The DY2‐based system yields a bulk‐heterojunction nanoparticle morphology that appears to balance phase separation and interfacial accessibility, consistent with ...

All‐Polyimide‐Mediated Liquid Metal Assembly on Aerogels for Breathable and Robust Electronic Skins

open access: yesAdvanced Materials, EarlyView.
An all‐polyimide‐mediated assembly strategy resolves the fundamental conflict between physiological breathability and electromechanical robustness in wearable electronics. By integrating a polyamic acid‐encapsulated liquid metal ink onto an ultralight polyimide aerogel, imidization‐induced contraction enables low‐temperature conductive activation and ...

Efficient Osmotic Energy Conversion Enabled by Self‐Standing COF Membranes With Varied Sulfonic Acid Group Density

open access: yesAdvanced Materials, EarlyView.
Self‐standing, strong sulfonated covalent organic framework membranes with varied ionic‐group density are developed for osmotic energy conversion. Optimized charge‐governed nanochannels enable highly selective ion transport, delivering a power density of 24.53 W m−2 under seawater/freshwater salinity gradients.

Precipitable Water Vapor Trends by Layer Over Florida

open access: yes
Precipitable Water Vapor (PWV) is the total amount of water vapor contained in a vertical column of the atmosphere. The PWV is an indicator of how much water is available for precipitation (Trenberth et al. 2005).

A Comparison of Four Methods for Determining Precipitable Water Vapor Content From Multi-Spectral Data [PDF]

open access: yes, 2001
Determining columnar water vapor is a fundamental problem in remote sensing. This measurement is important both for understanding atmospheric variability and also from removing atmospheric effects from remotely sensed data.

Spatial and Temporal Variability of Precipitable Water Vapor from Era-Interim Over Ethiopia During 2006-2012

open access: yes, 2013
Signals from the Global Positioning System (GPS) are used to retrieve the integrated amount of water vapor along the path between a transmitting satellite and a receiving station. This integrated quantity is called slant water vapor (SW). Measurements
