Understanding the cause of sea level rise along coastal zone for 2005–2021

open access: yesEnvironmental Research Communications, 2023
Understanding the coastal sea level budget (SLB) is essential to revealing the causes of sea level rise and predicting future sea level change. Here we present the coastal SLB based on multiple sets of sea level observations, including satellite ...

Microstructure, Thermal Transport, and Dry‐Sliding Tribology of Powder‐Metallurgy Al7075 Composites Reinforced With Sol–Gel‐Derived ZnO–rGO Hybrid Nanoparticles

open access: yesAdvanced Engineering Materials, EarlyView.
Sol–gel‐derived ZnO–rGO hybrid nanoparticles enable Al7075 powder‐metallurgy composites to achieve concurrent gains in hardness and thermal conductivity while markedly lowering friction and wear. The hybrid architecture couples ZnO‐based load support with rGO‐assisted lamellar sliding and heat spreading, revealing a promising route toward lightweight ...

Terrestrial waters and sea level variations on interannual time scale [PDF]

open access: yes, 2011
On decadal to multidecadal time scales, thermal expansion of sea waters and land ice loss are the main contributors to sea level variations. However, modification of the terrestrial water cycle due to climate variability and direct anthropogenic forcing ...

Oxygen‐Tunnel Indium Tin Oxide Vertical Channel Transistors with Enhanced Current Density and Reliability for Monolithic 3D Compute‐In‐Memory Systems

open access: yesAdvanced Functional Materials, EarlyView.
Oxygen‐tunnel (OT) indium tin oxide (ITO) vertical channel transistors (VCTs) enable reliable, high‐density gain‐cell memory for monolithic 3D integration. A sandwiched SiN/SiO2/SiN OT stack selectively regulates oxygen transport, suppressing parasitic electrode oxidation while stabilizing channel oxygen vacancies, thereby suppressing carrier injection

Contributions of Greenland and Antarctica to Global and Regional Sea Level Change [PDF]

open access: yesOceanography, 2016
While it is well known that the accelerating melting of the ice sheets of Greenland and Antarctica will increasingly raise global mean sea levels, it is less widely understood how the addition of meltwater from these ice sheets will affect regional ...

A process-based assessment of the sea-level rise in the northwestern Pacific marginal seas

open access: yesCommunications Earth & Environment, 2023
Because regional sea-level rise can threaten coastal communities, understanding and quantifying the underlying process contributing to reginal sea-level budget are essential.

Chiral Phase Change Nanomaterials

open access: yesAdvanced Functional Materials, EarlyView.
This work demonstrates reversible, non‐volatile phase transitions in chiral Ge2${\rm Ge}_2$Sb2${\rm Sb}_2$Te5${\rm Te}_5$ (GST) nanohelices for high‐speed optical modulation of chirality and dynamic control of the state of polarization (SOP). The chiral nanostructures are fabricated using a highly directional, wafer‐scale physical vapor deposition ...

Altimeter accuracy requirements for detecting changes in sea level rise [PDF]

open access: yes, 2012
All nations with a maritime border are concerned about changes in sea level, with an increase in sea level leading to flooding of coastal areas, damage to property, salinification of fresh water aquifers and destruction of valuable agricultural land ...

Earth's Energy Imbalance From the Ocean Perspective (2005–2019)

open access: yesGeophysical Research Letters, 2021
Earth's energy imbalance (EEI) represents the rate of global energy accumulation in response to radiative forcings and feedbacks. Ocean heat uptake (OHU) poses a vital constraint on EEI and its uncertainty.
