Model of selective laser melt
// Journal Covers
The present work describes continuum modeling of selective laser melting as envisioned for eventual support of part-scale modeling of this fabrication process to determine end-state information such as residual stresses and distortion.
Nanographene structure
// Journal Covers
The electronic transport in centimeter‐sized three‐dimensional bulk nanographene monoliths can be dynamically controlled via electrochemically induced surface charge density.
Ocean, earth, and molecule
// Journal Covers
The kinetics of carbonate exchange on the [NpO2(CO3)3]4− complex, shown here in ball-and-stick form, were measured as a function of solution pH.
Structure of an aneurysm
// Journal Covers
We used 14C birth dating of a main constituent of CAs, that is, collagen type I, as an indicator for biosynthesis and turnover of collagen in CAs in relation to human cerebral arteries to investigate this further.
Molecules, cityscape
// Journal Covers
Demonstrating the application of nanometer-scale secondary ion mass spectrometry (CAMECA NanoSIMS 50 ion probe) for 3D chemical imaging of individual atmospheric particles without any sample pre-treatment, such as sectioning of particles.
Earth and satellite
// Journal Covers
The ability to fabricate 4-level diffractive structures with 1 µm critical dimensions has been demonstrated for the creation of fast (∼f/3.1 at 633 nm) Fresnel zone lenses (FZLs) with >60% diffraction efficiency into the −1 focusing order and nearly complete suppression of 0 and +1 orders.
Simulations of ion distributions
// Journal Covers
We describe fully self-consistent time-dependent simulations of radio frequency (RF) generated ion distributions in the ion cyclotron range of frequencies and RF-generated electron distributions in the lower hybrid range of frequencies using combined Fokker–Planck and full wave electromagnetic field solvers.
Computed temperature field inside the target
// Journal Covers
A detailed computation of the temperature profile for liquid hydrogen inside a hollow shell, as is found in inertial confinement fusion research, shows that seeds are likely to form at the equatorial plane of the shell.
Temperature simulations
// Journal Covers
Experiments on the Titan laser at the Lawrence Livermore National Laboratory were carried out in order to study the properties of fast electrons produced by high-intensity, short pulse laser interacting with matter under conditions relevant to fast ignition.
