Thin Ice Target for $^{16}$O(p,p') experiment

open access: yes, 2000
A windowless and self-supporting ice target is described. An ice sheet with a thickness of 29.7 mg/cm$^2$ cooled by liquid nitrogen was placed at the target position of a magnetic spectrometer and worked stably in the $^{16}$O$(p,p')$ experiment at $E_{p}

Sulfate and MSA in the air and snow on the Greenland Ice Sheet [PDF]

open access: yes, 1994
Sulfate and methanesulfonic acid (MSA) concentrations in aerosol, surface snow, and snowpit samples have been measured at two sites on the Greenland Ice Sheet.

Functionalized Reduced Graphene Oxide‐Based Nanocomposite Hydrogels for Enhanced Osteogenesis in Bone Tissue Engineering

open access: yesAdvanced Healthcare Materials, EarlyView.
Charge‐opposed reduced graphene oxide fillers are co‐integrated into biopolymeric nanocomposite scaffolds, synergistically enhance osteogenesis. Multiscale characterization reveals how surface chemistry and porosity dictate ectopic mineral architecture.

Marine record of late quaternary glacial-interglacial fluctuations in the Ross Sea and evidence for rapid, episodic sea level change due to marine ice sheet collapse [PDF]

open access: yes
Some of the questions to be addressed by SeaRISE include: (1) what was the configuration of the West Antarctic ice sheet during the last glacial maximum; (2) What is its configuration during a glacial minimum; and (3) has it, or any marine ice sheet ...

Joint inversion estimate of regional glacial isostatic adjustment in Antarctica considering a lateral varying Earth structure (ESA STSE Project REGINA) [PDF]

open access: yes, 2017
A major uncertainty in determining the mass balance of the Antarctic ice sheet from measurements of satellite gravimetry, and to a lesser extent satellite altimetry, is the poorly known correction for the ongoing deformation of the solid Earth caused by

Ice sheets

open access: yes, 2007
Summary: The vast polar ice sheets are shrinking as our climate becomes warmer. Floating ice shelves and glacier tongues are thinning and even breaking up in both Greenland and Antarctica, probably because of the combined effects of warming ocean waters and increasing summer air temperatures.

Robust pH Sensing Using a Graphene Oxide and Covalent Organic Frameworks Composite for Gastro‐esophageal Reflux Disease Diagnosis

open access: yesAdvanced Healthcare Materials, EarlyView.
A stable composite pH sensor is developed by coating graphene oxide (GO) nanosheets with covalent organic frameworks (COFs) to improve stability and sensitivity in acidic environments. The GO/COFs sensor demonstrates high selectivity, linearity, and biocompatibility, offering a promising strategy for continuous pH monitoring in gastro‐esophageal reflux

A Modular Perfusion Bioreactor Platform for Simulating Bone Regeneration and Fracture Healing: Integrating Mechanical Loading and Dual Perfusion for Advanced In Vitro Models

open access: yesAdvanced Healthcare Materials, EarlyView.
A modular bioreactor platform was developed in order to replicate bone homeostasis and pathology, thereby integrating mechanical loading, dynamic perfusion, and a 3D‐printed microfluidic chamber. With precise control of environmental parameters and dual perfusion for composite tissue models, the system enhances physiological relevance for studying bone

The effect of a Holocene climatic optimum on the evolution of the Greenland ice sheet during the last 10 kyr

open access: yesJournal of Glaciology, 2018
The Holocene climatic optimum was a period 8–5 kyr ago when annual mean surface temperatures in Greenland were 2–3°C warmer than present-day values. However, this warming left little imprint on commonly used temperature proxies often used to derive the ...
