Topography‐Free Dual‐Lubricant Patterned Slippery Surfaces for Programmable Droplet Control and High‐Performance Water Harvesting

Small, EarlyView.
A patterned dual‐lubricant SLIPS creates interfacial energy asymmetry, guiding droplet migration without external actuation. Condensed droplets formed on the fluorinated‐oil‐infused regions migrate to the silicone‐oil‐infused domains, where rapid growth and coalescence occur.

Lactate inhibits glucose‐induced zigzag motility and enhances linear motility in bull spermatozoa by suppressing glycolysis

Andrology, EarlyView.
Abstract Background Energy metabolism and substrate balance are critical determinants of sperm motility and fertility. Linear motility is necessary for sperm forward movement, whereas hyperactivated motility is a prerequisite for fertilization. The preference of metabolic pathways depends on substrate availability which controls sperm motility. However,
