Authors:
Tiziana Fuoco

Angew Chem Int Ed Engl 2021 May 5. Epub 2021 May 5.

Kungliga Tekniska Hogskolan, Fibre and Polymer Technology, Teknikringen 56-58, 10044, Stockholm, SWEDEN.

The clever one-pot combination of two macromolecular concepts, ring-opening polymerization (ROP) and step-growth polymerization (SGP), is demonstrated to be a simple yet, powerful tool to design a library of sequence-controlled polymers with diverse and spatially regulated degradability functions. ROP and SGP, sequentially, occur at room temperature by switching the organo-catalytic conditions from basic to acidic, each allowing the encoding of specific degradable bonds. The ROP controls the sequence length and position of the degradability functions, while the SGP between the complementary vinyl ether and hydroxyl chain-end, enables the formation of acetal bonds and high molar mass copolymers.

Soft Matter 2021 May;17(17):4504-4516

Institute of Particle Technology, Friedrich-Alexander University Erlangen-Nürnberg, Cauerstrasse 4, 91058 Erlangen, Germany.

Microgels, consisting of a swollen polymer network, exhibit a more complex self-assembly behavior compared to incompressible colloidal particles, because of their ability to deform at a liquid interface or collapse upon compression. Here, we investigate the collective phase behavior of two-dimensional binary mixtures of microgels confined at the air/water interface. We use stimuli-responsive poly(N-isopropylacrylamide) microgels with different crosslinking densities, and therefore different morphologies at the interface. Read More

News from Mars: Two-Tier Paradox, Intracellular PCR, Chimeric Junction Shift, Dark Matter mRNA and Other Remarkable Features of Mammalian RNA-Dependent mRNA Amplification. Implications for Alzheimer's Disease, RNA-Based Vaccines and mRNA Therapeutics.

Ann Integr Mol Med 2021 ;2:131-173

Division of Molecular Medicine, Children's Hospital, USA.

Molecular Biology, a branch of science established to examine the flow of information from "letters" encrypted into DNA structure to functional proteins, was initially defined by a concept of DNA-to-RNA-to-Protein information movement, a notion termed the Central Dogma of Molecular Biology. RNA-dependent mRNA amplification, a novel mode of eukaryotic protein-encoding RNA-to-RNA-to-Protein genomic information transfer, constitutes the extension of the Central Dogma in the context of mammalian cells. It was shown to occur in cellular circumstances requiring exceptionally high levels of production of specific polypeptides, e. Read More

Confinement effects on the solvation structure of solvated alkaline metal cations in a single-digit 1T-MoS nanochannel: A first-principles study.

J Chem Phys 2021 Apr;154(16):164706

Material Science Division, Lawrence Livermore National Laboratory, Livermore, California 94550, USA.

Confinement plays an important role in determining ion transport in porous materials, which, in turn, may influence the performance of many energy storage and desalination devices. In this work, we combined density functional theory (DFT) with an implicit solvation model and ab initio molecular dynamics (AIMD) to investigate the effects of nanoconfinement on several solvated alkaline metal cations in a single-digit 1T-MoS nanochannel. Our DFT calculations with a solvation model indicated that cations with stronger hydration energy introduce a higher number of co-intercalated water molecules into the channel, consistent with early experimental observation obtained for MXene (2D transition metal carbide) channels.
