Sonoselective Transfection of Glioma Endothelium

Advanced Science, EarlyView.
Delivering non‐viral, gene‐bearing nanoparticles with thiol‐decorated surfaces to gliomas with focused ultrasound yields transfection tropism for endothelial cells. From this platform, “sonoselective” transfection of glioma endothelium is achieved via incorporation of an endothelial cell‐specific promoter.

Covalent Organic Framework Colloids With Core‐Shell Donor/Acceptor Architecture and Ultralong‐Lived Charge‐Separated States

Angewandte Chemie, EarlyView.
Uniform core‐shell colloidal particles of Covalent Organic Frameworks (COFs) are synthesized by a seeded growth of electron‐acceptor COF shells on electron‐donor COF cores. The resulting p‐n heterojunction enables efficient separation of photogenerated charges, which persist for minutes. These core‐shell COFs show efficient CO2 photoreduction to CO and

Comparison of Three Gas Chromatographic Methods—Identification of Terpenes and Terpenoids in Cannabis sativa L.

Applied Sciences
Terpenes and terpenoids content in cannabis plant was already studied in the past with three used methods. Since these works did not compare the content of these substances under the same conditions, we tried to make this comparison exactly.

Solvent extraction of PDMS tubing as a new method for the capture of volatile organic compounds from headspace [PDF]

Polydimethylsiloxane (PDMS) tubing is increasingly being used to collect volatile organic compounds (VOCs) from static biological headspace. However, analysis of VOCs collected using PDMS tubing often deploys thermal desorption, where samples are ...

Herbivory‐Induced Stomatal Opening Triggers the Dispersal of an Invasive Insect Herbivore

Advanced Science, EarlyView.
The invasive leafminer Phthorimaea absoluta uniquely manipulates plant defenses by inducing stomatal opening in tomato. This response, mediated by the stomatal regulator IQM1, enhances the release of the repellent volatile benzaldehyde. This volatile triggers the dispersal of adult moths, facilitates colonization of new hosts, and leads to rapid ...

Dialkyl Ethers and Sacrificial Zinc: Oxide Synthons for Calcium tert‐Butoxide Formation

Angewandte Chemie, EarlyView.
When treated with dialkyl ethers, [(BDI)Ca‐μ‐H‐Zn(t‐Bu)2(η6‐C7H8)] (BDI = HC{C(Me)NDipp}2 initiates a sequence of twofold ether dealkylation and oxide sequestration as tert‐butoxide in a process predicated on a combination of extreme basicity and a cooperative redox process administered by the dissimilar constituent metals. (Generative AI (ChatGPT) was

Optimization of Solid Phase Micro-Extraction (SPME) for Monitoring Occupational Exposure to Ethyl Benzene

Majallah-i Dānishgāh-i ̒Ulūm-i Pizishkī-i Qum, 2009
Background and Objectives: Analytical methods for volatile organic compounds (VOCs) in different samples need extraction of compounds, by applying hazardous solvents. Solid phase micro-extraction (SPME) is a solvent-free equilibrium extraction method, in

Constrained Forest Methane Sink by Thermal Adaptation of Soil Methanotrophs

Advanced Science, EarlyView.
Climate warming can stimulate methanotroph‐mediated CH4 oxidation in forest soils, thereby mitigating the increase in atmospheric CH4 concentrations. By integrating evidence from a macro‐climatic thermal gradient and a 70‐day incubation experiment, this study demonstrates that microbial methanotrophs can adapt to long‐term temperature changes at the ...
