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 ...

Higher-Order Nuclear-Polarizability Corrections in Atomic Hydrogen [PDF]

, 1997
Nuclear-polarizability corrections that go beyond unretarded-dipole approximation are calculated analytically for hydrogenic (atomic) S-states. These retardation corrections are evaluated numerically for deuterium and contribute -0.68 kHz, for a total ...

Validation of deuterium incorporation against sterol balance for measurement of human cholesterol biosynthesis

Journal of Lipid Research, 1998
To examine the validity of the deuterium (D) incorporation technique for measurement of human cholesterol synthesis rates, D uptake from D2O into cholesterol was compared to sterol balance in 13 subjects each under three controlled diet settings ...

Adsorption and Separation by Flexible MOFs

Advanced Materials, EarlyView.
Flexible metal–organic frameworks (MOFs) present significant potential for gas storage and separation due to their structural dynamic. This review explores the rationale behind the flexible MOFs' enhanced working capacity and separation factors. It also addresses key challenges, including phase transition kinetics, crystal robustness, cycling, shaping,

Supramolecular Conductive Hydrogels With Homogeneous Ionic and Electronic Transport

Advanced Materials, EarlyView.
Poly(3,4‐ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) based conductive hydrogels have received great attention in bioelectronics on account of their tissue‐like mechanical properties. However, inhomogeneous morphologies of the conducting PEDOT phase limits their electrical and mechanical properties. Here, supramolecular hydrogels with self‐

Deuteron Photodissociation in Ultraperipheral Relativistic Heavy-Ion on Deuteron Collisions

, 2003
In ultraperipheral relativistic deuteron on heavy-ion collisions, a photon emitted from the heavy nucleus may dissociate the deuterium ion. We find deuterium breakup cross sections of 1.38 barns for deuterium-gold collisions at a center of mass energy of

Continuous-Flow Analysis of δ17O, δ18O, and δD of H2O on an Ice Core from the South Pole

Frontiers in Earth Science, 2021
The δD and δ18O values of water are key measurements in polar ice-core research, owing to their strong and well-understood relationship with local temperature.

Moisture‐Dependent Vibrational Dynamics and Phonon Transport in Nanocellulose Materials

Advanced Materials, EarlyView.
Uptake of water in cellulose play an important role in modulating the structure and phonon transport. This study reports how moisture‐dependent structural modification relates to the vibrational dynamics and phonon transport and scattering of nanocellulose using inelastic neutron scattering and wide angle X‐ray scattering.

Current best estimates for the average lifespans of mouse and human leukocytes: reviewing two decades of deuterium‐labeling experiments

Immunological Reviews, 2018
Deuterium is a non‐toxic, stable isotope that can safely be administered to humans and mice to study their cellular turnover rates in vivo. It is incorporated into newly synthesized DNA strands during cell division, without interference with the kinetics
