Synthesis of high-molecular-weight poly(ε-caprolactone) via heterogeneous zinc-cobalt(III) double metal cyanide complex

open access: yesGiant, 2020
The synthesis of high-molecular-weight poly(ε-caprolactone)s (PCLs) with enhanced mechanical properties remains challenging. Here we demonstrate the heterogeneous catalysis for the ring-opening polymerization (ROP) of ε-caprolactone (ε-CL).

Generalised Functions as Linear Functionals on Generalized Functions [PDF]

open access: yes, 1984
We give a sketch of a rigorous foundation for the model for a symmetrical theory of generalised functions introduced earlier by the second author. On starting with a suitable subspace PC of the space S’ of tempered distributions, we introduce a space SGF of “new” generalised functions as a space of linear functionals on PC.

Preparation of Polyphosphazene Hydrogels for Enzyme Immobilization

open access: yesMolecules, 2014
We report on the synthesis and application of a new hydrogel based on a methacrylate substituted polyphosphazene. Through ring-opening polymerization and nucleophilic substitution, poly[bis(methacrylate)phosphazene] (PBMAP) was successfully synthesized ...

Highly Efficient One-Pot Synthesis of COS-Based Block Copolymers by Using Organic Lewis Pairs

open access: yesMolecules, 2018
A one-pot synthesis of block copolymer with regioregular poly(monothiocarbonate) block is described via metal-free catalysis. Lewis bases such as guanidine, quaternary onium salts, and Lewis acid triethyl borane (TEB) were equivalently combined and used ...

Manipulation of the through‐space interactions in diphenylmethane

open access: yesSmart Molecules, 2023
Through‐space interaction (TSI) has been proven to play an important role in the newly emerging clusteroluminescence (CL) phenomenon. However, it is still a big challenge to manipulate the TSI at the molecular level due to the unclear relationship ...

An easy gene assembling strategy for light-promoted transfection by combining host-guest interaction of cucurbit[7]uril and gold nanoparticles

open access: yesScientific Reports, 2017
Cucurbit[7]uril (CB[7]), a representative member of the host family cucurbit[n]uril, can host-guest interact with many guest molecules such as adamantane, viologen and naphthalene derivatives. This host-guest interaction provides an easy strategy in gene

Highly stretchable carbon aerogels

open access: yesNature Communications, 2018
Improved compressive elasticity was lately demonstrated for carbon aerogels but the problem of reversible stretchability remained a challenge. Here the authors use a hierarchical structure design and synergistic effects between carbon nanotubes and ...

Friction behavior of rough polydimethylsiloxane surfaces under hydrophobic polymer aqueous solution conditions

open access: yesPolymer Testing, 2021
Investigating the frictional behavior of polydimethylsiloxane (PDMS) with well-controlled roughness in complex fluids is important for biological and chemical applications.

Bayesian function‐on‐function regression for multilevel functional data [PDF]

open access: yesBiometrics, 2015
SummaryMedical and public health research increasingly involves the collection of complex and high dimensional data. In particular, functional data—where the unit of observation is a curve or set of curves that are finely sampled over a grid—is frequently obtained.
