Bio‐Inspired Mesoporous Solar Evaporator Enabled by Upcycled PET

Small, EarlyView.
Upcycled PET waste is converted into graphite‐containing porous foam for compound‐eye‐inspired solar evaporation. The resulting three‐dimensional evaporator combines a moldable porous framework with a hemispherical multi‐surface architecture, enabling angle‐insensitive solar exposure, capillary water transport, and efficient freshwater production under

Thermally Regulated Droplet Microfluidics Enables Uniform, Size‐Controllable DNA‐Nanoparticle Superlattices

Small, EarlyView.
Thermally regulated droplet microfluidics enables controlled assembly of DNA‐functionalized gold nanoparticles into uniform, size‐controllable superlattice crystals. Monodisperse droplets formed at elevated temperature suppress premature hybridization, followed by ultra‐slow cooling to promote near‐equilibrium growth.

Photo‐Activated Merging Cascades in Droplet Swarms Upon Synergistic Solvation of Surfactants

Small, EarlyView.
UV activates the motility of UV‐responsive droplets through a decylammonium/carbamate crystalline layer at the air/water interface. Upon merging with immobilized C12E3 surfactant droplets in the layer, hybrid droplets form which dissolve the layer due to synergistic solvation. In large droplet fields, this non‐linear behavior drives cascading events of

Tailoring Laser Powder Bed Fusion and Post‐Processing Parameters for JIS SKD61 Tool Steels: Surface Roughness, Microstructure, and Mechanical Properties

steel research international, EarlyView.
Laser powder bed fusion of JIS SKD61 tool steel is systematically optimized using a Taguchi design and ANOVA. Hatch spacing and layer thickness are identified as dominant parameters controlling surface roughness and tensile strength. Subsequent tempering at 600°C improves microstructural stability and mechanical performance, enabling high‐density SKD61

Agglomeration Behavior of Nonmetallic Particles on the Surface of Si‐Killed Liquid Steel Using HT‐CSLM: An In Situ Investigation

steel research international, EarlyView.
The in situ agglomeration behavior of semisolid Al–silicate inclusions in Si‐killed steel is studied using high‐temperature confocal scanning laser microscopy. Particle motion and interparticle forces at the steel/argon interface are quantified and compared with a modified capillary interaction model.

Study on the Instability of Two-Phase Flow in the Heat-Absorbing Tube of Trough Solar Collector

International Journal of Photoenergy, 2017
The Marangoni effect and Rayleigh-Benard effect in the two-phase region of solar trough heat-absorbing tube are simulated by FTM (front tracking method). Considering the Marangoni effect alone, although surface tension gradient and surface tension affect
