Role of Epoxide Functionalization of Amines for Development of Direct Air Capture Sorbents with High Cyclic Working Capacity at Low Desorption Temperatures

open access: yesAdvanced Science, EarlyView.
Appropriate butylene oxide (BO) functionalization of amines (polyethyleneimine (PEI1200 and PEI300) and tris(2‐aminoethyl)amine (TREN)) enables excellent cyclic working capacities (WCcyclic) at low desorption temperatures (40−70°C). Notably, 0.30BO‐PEI300‐SY and 0.54BO‐TREN‐SY show the highest WCcyclic at 45 and 40°C, respectively.

Statistical analysis of global surface air temperature and sea level using cointegration methods [PDF]

open access: yes
Global sea levels are rising which is widely understood as a consequence of thermal expansion and melting of glaciers and land-based ice caps. Due to physically-based models being unable to simulate observed sea level trends, semi-empirical models have ...

Multi‐scale Optimization on Interfacial Evaporative Cooling for Photovoltaic Performance Enhancement

open access: yesAdvanced Science, EarlyView.
This study presents a passive siphon‐driven interfacial evaporative cooling technology for photovoltaics. A multiscale multiphysics model is developed and validated experimentally. Results show that optimizing installation parameters reduces operating temperature by up to 22.3 °C and boosts power efficiency by 8.9%, offering a practical pathway for ...

Uncertainty estimates in regional and global observed temperature changes: A new data set from 1850 [PDF]

open access: yes, 2006
The historical surface temperature data set HadCRUT provides a record of surface temperature trends and variability since 1850. A new version of this data set, HadCRUT3, has been produced, benefiting from recent improvements to the sea surface ...

Land Covers and Climate Impacts on Land Surface Temperature in Putrajaya, Malaysia

open access: yesAsian Journal of Environment-Behaviour Studies, 2018
This study investigates the influence of surface heterogeneity on land surface temperature (LST). The land cover changes evaluation and historical climate data comparison were used in this study. Land cover, Normalised Difference Vegetation Index (NDVI), Normalised Difference Built-up Index (NDBI) and LST maps are produced to quantify the impacts of ...

Autonomous and Continuous Atmospheric Water Harvesting Using Modified Wood

open access: yesAdvanced Science, EarlyView.
A rigid, hydroxyl‐rich wood skeleton with graded channels is used as a multifunctional host to co‐incorporate a PNipam/PAA network and LiCl, creating a high‐performance sorbent for atmospheric water harvesting. The composite achieves rapid sorption, efficient low‐temperature desorption, and stable cycling, enabling a solar‐powered device with a high ...
