Optimized Lipid Nanoparticles with Tail‐Modified Ionizable Lipids for Safer mRNA Delivery

Advanced Science, EarlyView.
Systematic engineering of hydrophobic tail architecture in vitamin B5‐derived ionizable lipids establishes a comprehensive structure–activity relationship framework for mRNA delivery. Combined lipidtail and formulation optimization identifies TM1‐OPT3‐C, a lipid nanoparticle platform that improves efficacy–safety balance through efficient mRNA delivery,

Oxidation of Alkylaromatics

E-Journal of Chemistry, 2007
Hydroperoxide at α-position to the aromatic ring is the primary oxidation product formed. In all cases monoalkylbenzenes lead to the formation of benzoic acid.

Synthesis and Host–Guest Properties of Acyclic Pillar[n]naphthalenes

Frontiers in Chemistry, 2019
Here we report a new class of synthetic receptors, acyclic pillar[n]naphthalene (n = 2–4, Dimer, Trimer, and Tetramer) oligomers, which are made up of 2,3-diethoxynaphthalene units linked by methylene bridges at the 1- and 4-positions.

A Modular Standard Operating Procedure for Standardizing Lithium Metal Interfaces

Advanced Science, EarlyView.
A modular standard operating procedure (SOP) is developed to standardize lithium metal interfaces through sequential etching, brushing, and soaking. By transforming poorly controlled lithium surfaces into chemically uniform and structurally regulated interfaces, the framework improves electrochemical reproducibility, interfacial stability, and ...

Naphthalene plasmids in pseudomonads [PDF]

Journal of Bacteriology, 1982
A rapid method beginning with the direct lysis of bacteria in alkaline sodium dodecyl sulfate was used to detect naphthalene plasmids in pseudomonads. The strains NCIB 9816, PG, ATCC 17483, and ATCC 17484, which can grow on naphthalene as the sole source of carbon and energy, were examined. All except ATCC 17483 contained more than one plasmid.

N–O Dual Functional Group Transposition via Energy Transfer Photocatalysis

Advanced Science, EarlyView.
N–O dual functional group transposition (dFGT) enabled by the photocatalytic energy transfer (EnT) has been developed. This methodology is applicable to both activated and unactivated alkyl derivatives for dFGT, and it also successfully extended to N–N dFGT, demonstrating its general applicability.

Beyond Traditional Phenolics: Disulfide Bonds for Performance Enhancement of Aerospace Ablation‐Resistant Materials from Processing to Recycling

Advanced Science, EarlyView.
The dynamic disulfide bonds facilitated the development of high‐performance aerospace ablation‐resistant materials. At moderate temperature, the dissociation and recombination of disulfide bonds ensured excellent processability, mechanical properties, and recycling ability of phenolic resin; at high temperature, cleavage of disulfide bonds produced ...

One‐Pot Ruthenium‐Catalyzed Synthesis of Benzyl/Allyl‐Halide Substituted (dihydro)naphthalenes via Radical Benzannulation

ChemistryEurope
Herein, a selective, one‐pot synthetic route to reactive benzyl‐ and allyl‐halide‐substituted naphthalenes and dihydronaphthalenes from easily accessible 2,3‐aryl‐1,3‐butadiene substrates and simple halogenated alkanes, using [Cp*RuCl(PPh3)2] as the ...
