Dipole‐Engineered Conductive Additives for Ultrastable Interphase Evolution in High‐Areal‐Capacity Silicon Anodes

Advanced Functional Materials, EarlyView.
In the work reported herein, dipole‐engineered sulfonated carbon nanofibers enable conductive additives to actively regulate interphase formation in silicon anodes. Polar sulfonyl groups guide electrolyte decomposition to form a compact LiF‐rich interphase while promoting robust integration with silicon.

Graded‐Interface Dual‐Environment Hydrogel‐Polymer Electrolyte for Stabilized Anode and Sustained Cathode Kinetics in Aqueous Zinc‐Ion Batteries

Advanced Functional Materials, EarlyView.
A graded‐interface hydrogel‐polymer electrolyte decouples water activity to simultaneously stabilize the Zn anode and sustain cathode kinetics. The flexible design supports dendrite‐free cycling over 1600 h, high capacity in both MnO2 and V2O5 full cells, and stable pouch‐cell performance under bending, resolving the fundamental water conflict in ...

Engineering Pendant Group Chemistry to Control Hydrophilicity and Oxidative Degradation of Thioketal‐Based Biomaterials

Advanced Functional Materials, EarlyView.
Thioketal (TK) polymers are promising biomaterials due to their selective biodegradation by reactive oxygen species (ROS), but they respond slowly to physiologic doses of ROS. Here, the TK bond's pendant groups are modified to enhance the degradation of TK‐based implants both in vitro and in vivo.

Ecotoxicological Quantitative Structure–Activity Relationships for Pharmaceuticals

Bulletin of Environmental Contamination and Toxicology, 2007
This paper examined active pharmaceutical ingredients (APIs) acute ecotoxicological modes of action (MOA). It was concluded that the vast majority of APIs acute MOA was non-specific narcosis as; 85% out of 59 APIs had an excess toxicity ratio

Quantitative structure-activity relationships

1979
Designing of biologically active molecules on a rational basis is of utmost importance to medicinal chemists. Until about the late 1950’s most of the structure-activity correlations were emperical and qualitative. Although attempts have been made to apply quantitative methods to biological activity since last century, a major effort in this field has ...

Quantitative Structure-Activity Relationships and Carminative Activity

Journal of Pharmaceutical Sciences, 1978
Carminative activities of 34 alcohols, esters, ethers, phenols, and carbonyl compounds were determined using the guinea pig isolated ileum preparation and are expressed as the ability to produce a 50% inhibition (ID50) of a standard response to carbachol. Aqueous solubilities were measured at 37 degrees using either UV absorption or GLC.

Toxicity and quantitative structure-activity relationships of colchicines

Journal of Medicinal Chemistry, 1981
A method for extracting LD50 values from antitumor test data is described. A quantitative structure--activity relationship (QSAR) for 7- and 10-substituted colchicines is presented. This correlation equation closely parallels that which had been derived earlier for potency. This result indicates that attempts to modify 7- and 10-substituted colchicines
