One‐Pot Transition‐Metal‐Free Methods for the Synthesis of All Three Bonds of the Alkyne's Triple Bond

Chemistry – A European Journal, EarlyView.
One‐pot transition‐metal‐free methods for the synthesis of all three bonds of the alkyne's triple bond are reviewed. After analysis of several named reactions and discussion of improvements, recent advances in the synthesis of alkynes are discussed. Each section contains a proposed reaction mechanism and analysis of the strengths and weaknesses of the ...

Optimal model‐based design of experiments for parameter precision: Supercritical extraction case

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study investigates the process of chamomile oil extraction from flowers. A parameter‐distributed model consisting of a set of partial differential equations is used to describe the governing mass transfer phenomena in a cylindrical packed bed with solid chamomile particles under supercritical conditions using carbon dioxide as a solvent ...

Hydrothermal Alkali‐Assisted Growth of Highly In‐Plane Crystallized Poly(Heptazine Imide) for Photocatalytic H2O2 Production

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A new re‐crystallization strategy was employed to design a highly crystallized poly(heptazine imide) photocatalyst, achieving strong light absorption capacity, accelerated separation/migration of photocarriers, and enhanced proton extraction capability simultaneously.

Transendocardial injection of expanded autologous CD34+ cells after myocardial infarction: Design of the EXCELLENT trial

ESC Heart Failure, Volume 12, Issue 2, Page 1455-1463, April 2025.
Abstract Aims The extent of irreversible cardiomyocyte necrosis after acute myocardial infarction (AMI) is a major determinant of residual left ventricular (LV) function and clinical outcome. Cell therapy based on CD34+ cells has emerged as an option to help repair the myocardium and to improve outcomes.

Mediated Futures in Anesthetic Space

Media Theory
Media are intimately connected to the future. They are simultaneously posited as encouraging speculation and foreclosing futures. Through an examination of the “canal craze” at the turn of the twentieth century in which the telescopic lens was believed ...
