Effect of lattice volume and strain on the conductivity of BaCeY-oxide ceramic proton conductors

, 2012
In-situ electrochemical impedance spectroscopy was used to study the effect of lattice volume and strain on the proton conductivity of the yttrium-doped barium cerate proton conductor by applying the hydrostatic pressure up to 1.25 GPa.

Energy expenditure of nonexercise activity [PDF]

The American Journal of Clinical Nutrition, 2000
We found recently that changes in nonexercise activity thermogenesis (NEAT) mediate resistance to weight gain with overfeeding in sedentary adults. A potentially important, yet seldom investigated, component of NEAT is the energy expenditure of fidgeting-like activities.Our goal was to measure changes in energy expenditure with fidgeting-like ...

Measuring the activation energy barrier for the nucleation of single nanosized vapor bubbles

Proceedings of the National Academy of Sciences of the United States of America, 2019
Significance While it is generally believed that bubble nucleation process is highly heterogeneous and stochastic, little is known on the nucleation rate and activation energy barrier of single nanosized bubble due to the lack of suitable techniques.

Structural insights into lacto‐N‐biose I recognition by a family 32 carbohydrate‐binding module from Bifidobacterium bifidum

FEBS Letters, EarlyView.
Bifidobacterium bifidum establishes symbiosis with infants by metabolizing lacto‐N‐biose I (LNB) from human milk oligosaccharides (HMOs). The extracellular multidomain enzyme LnbB drives this process, releasing LNB via its catalytic glycoside hydrolase family 20 (GH20) lacto‐N‐biosidase domain.

Coupled-barrier diffusion: the case of oxygen in silicon

, 1995
Oxygen migration in silicon corresponds to an apparently simple jump between neighboring bridge sites. Yet, extensive theoretical calculations have so far produced conflicting results and have failed to provide a satisfactory account of the observed $2.5$

Composition-dependent apparent activation-energy and sluggish grain-growth in high entropy alloys

Materials Research Letters, 2019
Experimental results reveal that the apparent activation-energy for grain-growth in an fcc-based AlxCoCrFeNi high entropy alloy (HEA) system increases from 179 to 486 kJ/mol when the Al content increases from x = 0.1 to 0.3.

The Caenorhabditis elegans DPF‐3 and human DPP4 have tripeptidyl peptidase activity

FEBS Letters, EarlyView.
The dipeptidyl peptidase IV (DPPIV) family comprises serine proteases classically defined by their ability to remove dipeptides from the N‐termini of substrates, a feature that gave the family its name. Here, we report the discovery of a previously unrecognized tripeptidyl peptidase activity in DPPIV family members from two different species.

Role of Vanadium Addition on Hot Deformation Behavior of Aluminum Alloy 5083

Metals, 2019
The effect of V addition on the hot deformation behavior of AA5083 was investigated. Single axial compression tests were conducted on the cast and homogenized samples with strain rates ranging from 0.01 to 10 s−1 and deformation temperatures ...

Physico-chemical and spectroscopic investigation of flavonoid dispersed CnTAB micelles

Royal Society Open Science, 2022
In this study, kaempferol (0.2 m/mmol kg−1) dispersed cationic surfactant micelles were prepared as a function of alkyltrimethylammonium bromide (CnTAB) hydrophobicity (C = 12 to C = 16).
