Macronutrients as sources of food energy. [PDF]

, 2005
This background paper considers the extent to which the development of new recommendations for dietary energy requirements needs to account for the macronutrient (fat, carbohydrate, protein and alcohol) profiles of different diets.

Pressure Driven Alkane Dehydrogenation by Palladium Metal

Advanced Materials Interfaces, 2023
Dehydrogenation of alkanes is of increasing importance in fulfilling global demand for olefins and offers a potential source of carbon‐neutral hydrogen as a co‐product. Currently commercial dehydrogenation processes occur at high‐temperatures (500–900 °C)

Size effect of the surface energy density of nanoparticles [PDF]

, 2015
The surface energy density of nanoparticles exhibits an obviously size-dependent behavior. However, how the surface energy density changes with the diameter of nanoparticles is still ambiguous. Based on a recently developed continuum theory considering

High deuteron and neutron yields from the interaction of a petawatt laser with a cryogenic deuterium jet

Frontiers in Physics, 2023
A compact high-flux, short-pulse neutron source would have applications from nuclear astrophysics to cancer therapy. Laser-driven neutron sources can achieve fluxes much higher than spallation and reactor neutron sources by reducing the volume and time ...

ENERGY–MOMENTUM DENSITY OF GRAVITATIONAL WAVES [PDF]

International Journal of Modern Physics A, 2008
In this paper, we elaborate the problem of energy–momentum in general relativity by energy–momentum prescriptions theory. Our aim is to calculate energy and momentum densities for the general form of gravitational waves. In this connection, we have extended the previous works by using the prescriptions of Bergmann and Tolman.

Dietary Energy Density in Relation to Subsequent Changes of Weight and Waist Circumference in European Men and Women

, 2009
Background - Experimental studies show that a reduction in dietary energy density (ED) is associated with reduced energy intake and body weight.

Nanotwin hardening in a cubic chromium oxide thin film

APL Materials, 2015
NaCl-type (B1) chromium oxide (CrO) has been expected to have a high hardness value and does not exist as an equilibrium phase. We report a B1-based Cr0.67O thin film with a thickness of 144 nm prepared by pulsed laser deposition as an epitaxial thin ...

Variations in the saturation magnetization of nanosized NiFe2O4 particles on adsorption of carboxylic acids

Journal of Asian Ceramic Societies, 2014
This work investigated magnetization changes in NiFe2O4 nanoparticles induced by the adsorption of a series of carboxylic acids. The application of formic acid resulted in a significant 8.6% decrease in the magnetization of NiFe2O4 nanoparticles at 18 ...

Electrocoagulation with a nanosecond pulse power supply to remove COD from municipal wastewater using iron electrodes

International Journal of Electrochemical Science, 2020
Electrocoagulation (EC) with iron electrodes was used to remove the chemical oxygen demand (COD) of municipal wastewater. A nanosecond pulse power supply (NSP) was evaluated and compared with direct current (DC).

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative
