The Preaponeurotic Fat Advancement Pedicle for Correction of Upper Eyelid Volume Asymmetry: A Case Series.

Preoperative volume asymmetry in the upper eyelid sulci can pose a challenge in achieving symmetry after upper eyelid blepharoplasty. Reported methods to improve volume asymmetry include the use of soft tissue filler and various surgical techniques. The authors present 6 cases where a central preaponeurotic fat advancement pedicle was utilized during upper eyelid blepharoplasty for improved upper eyelid symmetry (Fig.

Production of Carbon Fibers Using a Molten Cu-In Catalyst for Methane Pyrolysis.

Molten metal catalysts for methane pyrolysis and dry reforming are becoming recognized for their potential in decarbonization efforts. Their use in bubble column reactors facilitates continuous operation by allowing the produced carbon to float to the surface for removal. While most reported molten metals produce low-value amorphous carbon or graphitic sheets containing some metals, our study introduces a Cu-In alloy that selectively produces high-purity carbon nanofibers.

Engineering modular and tunable single-molecule sensors by decoupling sensing from signal output.

Biosensors play key roles in medical research and diagnostics. However, the development of biosensors for new biomolecular targets of interest often involves tedious optimization steps to ensure a high signal response at the analyte concentration of interest. Here we show a modular nanosensor platform that facilitates these steps by offering ways to decouple and independently tune the signal output as well as the response window.
