Decoding Viral Transmission Dynamics in Structured Populations Using a Microfluidic Herd‐Immunity‐on‐a‐Chip Platform

open access: yesAdvanced Science, EarlyView.
A microfluidic Herd‐Immunity‐on‐a‐Chip experimentally recreates structured contact networks to quantify viral transmission dynamics. By controlling susceptible, infected, and non‐susceptible populations, the platform reveals how contact topology governs the reproduction number, outbreak propagation, herd‐immunity–like behavior, and intervention ...

Piperazine-Linked Metalphthalocyanine Frameworks for Highly Efficient Visible-Light-Driven H2O2 Photosynthesis

open access: yes, 2022
Artificial photosynthesis of H2O2 from O2 reduction provides an energy-saving, safe, and green approach. However, it is still critical to develop highly active and selective 2e– oxygen reduction reaction photocatalysts for efficient H2O2 production owing

Dual pKa Lipid Nanoparticles for Lung‐tropic mRNA Delivery and pH‐Programmed Endosomal Escape

open access: yesAdvanced Science, EarlyView.
Lipid nanoparticles’ bottleneck lies in low endosomal escape efficiency and liver‐dominant delivery after intravenous administration. To overcome these limitations, we present a stepwise pH‐programmed lipid nanoparticle system enabled by our newly synthesized ionizable lipid.

MODELING POLARIZATION CURVE IN AN AQUEOUS CARBONATED SOLUTION OF PIPERAZINE

open access: yesJournal of Engineering and Sustainable Development, 2022
A polarization curve model is developed for carbon steel in an aqueous carbonated solution of piperazine (PZ). This model has been used to generate the polarization curve and control the parameters relevant to the corrosion rate of carbon steel in the PZ-

Piperazine Bridged Thianorrole Dimer

open access: yes, 2023
Oxidative cyclization of open chain thiabilanes yielded the first examples of unique piperazine bridged thianorrole dimers instead of the expected thianorrole monomer.

EphB1 Receptor Blockade Augments Morphine Antinociception via Inhibiting GRK2‐Mediated µ‐Opioid Receptor Internalization

open access: yesAdvanced Science, EarlyView.
Administration of opioids activates ephrinB2‐EphB1 receptor signaling. Activated EphB1 receptors induce GRK2‐mediated phosphorylation of MOR at Ser375, which initiates the internalization of MOR and reduces opioid antinociception at the behavioral level. ABSTRACT Opioids are the primary treatment for severe pain in clinical practice.

Crystal structure of 7-hydroxy-8-[(4-methylpiperazin-1-yl)methyl]-2H-chromen-2-one

open access: yesActa Crystallographica Section E: Crystallographic Communications, 2016
In the title compound, C15H18N2O3, the coumarin ring is essentially planar, with an r.m.s. deviation of 0.012 Å. An intramolecular O—H...N hydrogen bond forms an S(6) ring motif. The piperazine ring adopts a chair conformation.
