Multidimensional Perovskite Solar Cells: What's Next after 3D/2D?

Advanced Energy Materials, EarlyView.
The frontier of low‐dimensional/3D perovskite interfaces is explored, moving beyond the well‐established 2D/3D interfaces. This discussion underscores the potential of combining 1D and 0D perovskites with the 3D structure, showcasing new prospects and challenges in material design. This reveals the pivotal role of the molecular structure of the organic

A new method for the separation of androgens from estrogens and for the partition of estriol from the estrone-estradiol fraction: with special reference to the identification and quantitative microdetermination of estrogens by ultraviolet absorption spectrophotometry [PDF]

, 1948
It is recognized generally that a qualitative and quantitative knowledge of the excretion pattern of the urinary estrogens is one index to an understanding of the functional activity of the ovary and adrenal cortex.

Metabolic impact of endogenously produced estrogens by adipose tissue in females and males across the lifespan

Frontiers in Endocrinology
The aged population, expected to double by 2050, makes up a large proportion of people living with metabolic disease. Obesity rates in the elderly are rapidly increasing, with estimates that nearly 40% of men and women over the age of 60 are classified ...

$\Delta ^{9,11}$-Estrone derivatives as potential antiproliferative agents: synthesis, in vitro biological evaluation and docking studies

Comptes Rendus. Chimie, 2020
A series of ${\Delta }^{{9,11}}$-estrone derivatives with A- and D-ring modifications has been synthesized and evaluated as antiproliferative agents. The cytotoxicity was assessed in six cell lines (MCF-7, T47-D, LNCaP, HepaRG, Caco-2 and NHDF) by the 3-(

A Sulfuryl Group Transfer Strategy to Selectively Prepare Sulfated Steroids and Isotopically Labelled Derivatives

Frontiers in Molecular Biosciences, 2021
The treatment of common steroids: estrone, estradiol, cortisol, and pregnenolone with tributylsulfoammonium betaine (TBSAB) provides a convenient chemoselective conversion of the steroids alcohol/phenol moiety to the corresponding steroidal organosulfate.

Monitoring Receptor Clustering by Aggregation‐Induced Emission

ChemPlusChem, EarlyView.
Receptor clustering induced by molecular recognition: AIE‐functionalized bisphosphonate receptors are embedded in a lipid bilayer. Upon addition of a cationic messenger, they undergo dimerization and send out a fluorescence signal. This study introduces a simple signal transduction system that mimics the receptor tyrosine kinase mechanism by employing ...
