Spiroorthocarbonate as shrinkage resistance for UV-curing 3D printing: UV-curing kinetics, mechanical properties and volume shrinkage

eXPRESS Polymer Letters, 2021
Spiroorthocarbonates (SOCs) exhibit good shrinkage resistance with ring-opening polymerization initiated by a cationic photoinitiator, with potential application in reducing the volume shrinkage by C=C double bond polymerization on three-dimensional (3D)

Copolymerization of ε-caprolactone with Epichlorohydrin by a Green Catalyst, Maghnite [PDF]

, 2012
Most of the cationic initiators used in the synthesis of copolymers are expensive. They may be poisoned by products of the reaction or impurities present in the monomer feed, and contain heavy metals, such as chromium, mercury, antimony, etc., that ...

Metal-Free Stereoselective Cationic Polymerization of Vinyl Ethers by Employing a Confined Brønsted Acid as the Catalyst [PDF]

, 2021
The properties of poly(vinyl ether)s (PVEs) are highly dependent on their tacticity, and the appealing thermoplastics features of isotactic PVEs have drawn considerable efforts to develop stereoselective cationic polymerization methods to access this ...

Assembling structurally customizable synthetic carriers of siRNA through thermodynamically self-regulated process

Asian Journal of Pharmaceutical Sciences, 2020
This study demonstrates that our previously reported polywraplex, a synthetic siRNA carrier consisting of a uni-molecular polyplex core of customizable size and a self-assembled tri-block copolymer envelop, may be constructed using dendrimers as the ...

Golgi enzymes are retrieved from the plasma membrane to the trans‐Golgi network

FEBS Letters, EarlyView.
Golgi enzymes are traditionally considered resident proteins retained within the Golgi apparatus. Here, we demonstrate that a subset transiently reaches the cell surface and is subsequently retrieved to the trans‐Golgi network via retrograde transport. Using a nanobody‐based toolkit, we uncover a dynamic trafficking cycle of several Golgi enzymes.

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

FEBS Letters, EarlyView.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?
