Liquid‐Phase Syngas‐To‐Methanol at Low Temperature: Mixed Alcohol Solvent‐Controlled Pathways for Circular Carbon Manufacturing

ChemSusChem, Volume 19, Issue 5, 13 March 2026.
Low‐temperature liquid‐phase methanol synthesis from syngas was demonstrated over CuO/ZnO/Al2O3 catalysts using mixed alcohol solvents. Solvent composition controls ester intermediate and methanol productivity. Methanol is a primary platform chemical for circular manufacturing.

Real-time helium bubble growth in tungsten by in-situ GISAXS

Nuclear Materials and Energy
Nuclear fusion, as a carbon-free energy source, is actively pursued by the international community. However, the irradiation by helium (He) of the walls facing the plasma can lead to important damages at the surface and deeper in the bulk, affecting the ...

Flow visualization of discrete hole film cooling for gas turbine applications [PDF]

Film injection from discrete holes in a three row staggered array with 5-diameter spacing is studied. The boundary layer thickness-to-hole diameter ratio and Reynolds number are typical of gas turbine film cooling applications.

Helium bubbles evolution mechanism of SA508-3/52 joint and its effect on nanoindentation hardness and swelling

Heat Treatment and Surface Engineering
After metallographic corrosion of dissimilar metal welded joints, a distinct uncorroded bright band, referred to as the ‘white bright band’ (WBB), is often observed on the austenite side immediately adjacent to the fusion line.

Temperature-dependent bubble growth under synergistic interactions of hydrogen and helium in tungsten

Nuclear Fusion
A novel theoretical model based on modified diffusion rate equations is proposed to simulate the retention of hydrogen isotopes and the dynamics of bubble growth in tungsten (W) when exposed to simultaneous hydrogen (H) and helium (He) plasma ...

Effects of vortex flaps on the low-speed aerodynamic characteristics of an arrow wing [PDF]

Tests were conducted in the Langley 12-foot low-speed wind-tunnel to determine the longitudinal and lateral-directional aerodynamic effects of plain and tabbed vortex flaps on a flat-plate, highly swept arrow-wing model.

Mechanics of liquid helium in a partially filled rotating dewar in low gravity with application to Gravity Probe-B [PDF]

The Gravity Probe-B spacecraft is composed largely of a liquid helium dewar containing an experiment package. It is shown that an unsymmetric liquid helium distribution in the dewar can cause unacceptably high forces, gravitational and gravity gradient ...
