The solvation of ions changes the physical, chemical and thermodynamic properties of water, and the microscopic origin of this behaviour is believed to be ion-induced perturbation of water's hydrogen-bonding network. Here we provide microsc...
Phase-specific RNA accumulation and duplex thermodynamics in multiphase coacervate models for membraneless organelles [0.03%]
多相凝聚滴模型中的阶段特异性RNA累积及双链热力学性质研究

Liquid-liquid phase separation has emerged as an important means of intracellular RNA compartmentalization. Some membraneless organelles host two or more compartments serving different putative biochemical roles. The mechanisms for, and fun...
Controlled masking and targeted release of redox-cycling ortho-quinones via a C-C bond-cleaving 1,6-elimination [0.03%]
通过C-C键断裂的1,6-消除反应对红ox循环苯醌进行可控掩蔽及目标释放

Lavinia Dunsmore et al.
Natural products that contain ortho-quinones show great potential as anticancer agents but have been largely discarded from clinical development because their redox-cycling behaviour results in general systemic toxicity. Here we report conj...
Planar π-extended cycloparaphenylenes featuring an all-armchair edge topology [0.03%]

The [n]cycloparaphenylenes ([n]CPPs)-n para-linked phenylenes that form a closed-loop-have attracted substantial attention due to their unique cyclic structure and highly effective para-conjugation leading to a myriad of fascinating electro...
Mechanically axially chiral catenanes and noncanonical mechanically axially chiral rotaxanes [0.03%]

Chirality typically arises in molecules because of a rigidly chiral arrangement of covalently bonded atoms. Less generally appreciated is that chirality can arise when molecules are threaded through one another to create a mechanical bond. ...

Carbon dioxide is inexpensive and abundant, and its prevalence as waste makes it attractive as a sustainable chemical feedstock. Although there are examples of copolymerizations of CO2 with high-energy monomers, the direct copolymerization ...
Sustainable polyesters via direct functionalization of lignocellulosic sugars [0.03%]
通过木质纤维素糖的直接官能化制备可持续聚酯

The development of sustainable plastics from abundant renewable feedstocks has been limited by the complexity and efficiency of their production, as well as their lack of competitive material properties. Here we demonstrate the direct trans...
Photocaged 5' cap analogues for optical control of mRNA translation in cells [0.03%]
用于细胞内光学控制mRNA翻译的光封闭5'帽类似物

Nils Klöcker et al.
The translation of messenger RNA (mRNA) is a fundamental process in gene expression, and control of translation is important to regulate protein synthesis in cells. The primary hallmark of eukaryotic mRNAs is their 5' cap, whose molecular c...

The cytoskeleton is an essential component of a cell. It controls the cell shape, establishes the internal organization, and performs vital biological functions. Building synthetic cytoskeletons that mimic key features of their natural coun...
