Techno‐Economic Analysis of Polylactic Acid from Corn Stover: Understanding Uncertainty and Variability via Artificial Intelligence Tools

open access: yesAdvanced Sustainable Systems, EarlyView.
This study analyses the uncertainty and variability existing in the economic performance of polylactic acid (PLA) production, via integrating techno‐economic analysis with process models and Monte Carlo simulation enabled by artificial intelligence. The results show that the minimum selling price varies from $2,107 to $3076/t PLA.

A Mechanochemical Kolbe–Schmitt Reaction: Catechol Carboxylation Provides Building Blocks for Renewable Plasticizers

open access: yesAngewandte Chemie, EarlyView.
A mechanochemical Kolbe–Schmitt reaction of disodium catecholate enables the synthesis of mono‐ and dicarboxylated catechols at low temperature and CO2 pressure. Directly derivatizing the resulting carboxylic acid and phenolic moieties in the obtained mixture provides plasticizer blends with efficiencies competitive to commercial benchmarks.

Low YTHDC1 Expression Upregulates FSCN1 to Promote Nuclear F‐Actin Formation and Facilitate Double‐strand DNA Breaks Repair in TMZ‐Resistant Glioblastoma

open access: yesAdvanced Science, EarlyView.
This study revealed that low expression of YTHDC1 in TMZ‐resistant GBM cells leads to increased FSCN1 expression, which is suppressed by m6A modification. FSCN1 activates the CDC42/N‐WASP/Arp2/3 axis in the cell nucleus by recruiting the guanine nucleotide exchange factor (GEF) family member FGD1, thereby promoting F‐actin polymerization in the nucleus.

Microwave Ultrafast Heating on Iron‐based Nanogap Catalysts for CO2 Reduction Coupling with Coke Removal

open access: yesAdvanced Science, EarlyView.
This study employs a nanogap‐induced microwave discharge strategy to pretreat coke deposits on iron‐based catalysts with engineered nanogaps, causing ultrarapid heating to 1990 K within seconds, selectively eliminating >70% surface carbon deposits and converting waste plastics and greenhouse gases into syngas.

Biomimetic Adaptive Hydrothermal Balance Fabric‐Based Dual‐Interface Solar Evaporator for Efficient and Stable Desalination

open access: yesAdvanced Science, EarlyView.
This study combines the biological structure of octopuses with the “3D structure” of spacer fabrics to fabricate a dual‐interface solar evaporator with adaptive hydrothermal balance. Water adaptation is achieved through the differentiated design of the upper and lower layers, and dynamic hydrothermal balance is realized by dynamically regulating the ...

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]

open access: yes, 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.
