Atomic Deuterium Adsorbed on the Surface of Liquid Helium [PDF]

, 2000
We investigate deuterium atoms adsorbed on the surface of liquid helium in equilibrium with a vapor of atoms of the same species. These atoms are studied by a sensitive optical method based on spectroscopy at a wavelength of 122 nm, exciting the 1S-2P ...

Fast‐Responding O2 Gas Sensor Based on Luminescent Europium Metal‐Organic Frameworks (MOF‐76)

Advanced Functional Materials, EarlyView.
Luminescent MOF‐76 materials based on Eu(III) and mixed Eu(III)/Y(III) show rapid and reversible changes in emission intensity in response to O2 with very short response times. The effect is based on triplet quenching of the linker ligands that act as photosensitizers. Average emission lifetimes of a few milliseconds turn out to be mostly unaffected by

Double radiative pion capture on hydrogen and deuterium and the nucleon's pion cloud

, 2007
We report measurements of double radiative capture in pionic hydrogen and pionic deuterium. The measurements were performed with the RMC spectrometer at the TRIUMF cyclotron by recording photon pairs from pion stops in liquid hydrogen and deuterium ...

Precise calculation of transition frequencies of hydrogen and deuterium based on a least-squares analysis [PDF]

, 2005
We combine a limited number of accurately measured transition frequencies in hydrogen and deuterium, recent quantum electrodynamics (QED) calculations, and, as an essential additional ingredient, a generalized least-squares analysis, to obtain precise ...

Controlled Release of Human Dental Pulp Stem Cell‐Derived Exosomes from Hydrogels Attenuates Temporomandibular Joint Osteoarthritis

Advanced Healthcare Materials, EarlyView.
Exosomes can reduce tissue damage in temporomandibular joint osteoarthritis (TMJOA), but rapid clearance limits their efficacy. This study encapsulates exosomes in hyaluronic acid hydrogels for controlled release. In a rat model, hydrogel‐encapsulated exosomes outperform free exosomes in preserving bone integrity and reducing tissue destruction ...

Hydrogeochemical characteristics of the River Sava watershed in Slovenia

Geologija, 2007
The River Sava is a typical HCO3- – Ca2+ – Mg2+ River. Total alkalinity increases in the part of the watershed composed of carbonate and clastic rocks, which are less resistant to weathering processes.

Thermoresponsive BrushGel Microcarriers for Efficient Cell Expansion and Enzyme‐Reduced Harvesting

Advanced Healthcare Materials, EarlyView.
Askari et al, report on temperature‐responsive microcarriers to minimize enzyme use and cost in dynamic cultures. Abstract Scaling up cell therapy requires efficient expansion of high‐quality cells. Microcarrier(MC)‐based systems offer high surface‐to‐volume ratios and reduce culture media usage.

Origins of harvested Mallards from Lake St. Clair, Ontario: a stable isotope approach

Avian Conservation and Ecology, 2019
Determining origins of waterfowl is important for establishing appropriate management and conservation strategies. In North America, much information is available from long-term mark-recapture programs involving banding on breeding or molting grounds ...

Heavy hydrogen in the stratosphere [PDF]

, 2003
We report measurements of the deuterium content of molecular hydrogen (H2) obtained from a suite of air samples that were collected during a stratospheric balloon flight between 12 and 33 km at 40º N in October 2002. Strong deuterium enrichments of up to

Generalizing Gelatin Methacryloyl Granular Hydrogel Fabrication Using Stable Microgels with Predictable Stiffness

Advanced Healthcare Materials, EarlyView.
Gelatin methacryloyl (GelMA) granular hydrogel scaffolds (GHS) are fabricated using a generalized two‐step photocrosslinking approach to yield stable (non‐dissolving) microgels suitable for in situ covalent assembly under physiological conditions. A phase diagram is developed to define the interplay between individual microgel stability and scaffold ...
