Synthesis and antimicrobial activity of a new series of 1,4-dihydropyridine derivatives [PDF]

open access: yesJournal of the Serbian Chemical Society, 2011
A series of 1,4-dihydropyridine derivatives (1a–g) were prepared from Hantzsch syntheses. The compounds 1a–g were reacted with thiosemicarbazide to give the new series of compounds 2a–g. IR, 1H-NMR, 13C-NMR, mass spectral and elemental analysis confirmed

Condensation-Incompetent Ketosynthase Inhibits trans-Acyltransferase Activity

open access: yes, 2019
Nonelongating modules with condensation-incompetent ketosynthase (KS0) are frequently found in many trans-acyltransferase polyketide synthases (trans-AT PKS). KS0 catalyzes translocation of carbon chain without decarboxylative condensation.

Titanium Suboxides Responsible for Electronic Anomaly Near Room Temperature in the Ti3C2Tx MXene

open access: yesAdvanced Functional Materials, EarlyView.
Our multi‐technique study reveals that the near‐room‐temperature anomaly in Ti3C2Tx MXene is linked to titanium suboxide nanodomains, including Ti3O5, embedded within the MXene host. Their temperature‐driven transformation provides an alternative explanation to solvent‐ and swelling‐based models and offers new insight into the thermally activated ...

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

open access: yesAdvanced 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.

Filmwise condensation on a horizontal tube in the presence of forced convection and non-condensing gas

open access: yes, 1982
PhDAccurate and repeatable heat-transfer data have been obtained for filmwise condensation from pure vapours (steam and Refrigerant 113) and vapour-gas (steam-air, steam-hydrogen, Refrigerant 1 13-air and Refrigerant 113- hydrogen) mixtures flowing

3D Printing Innovations in Polymeric Porous and Patterned Architecture

open access: yesAdvanced Functional Materials, EarlyView.
Polymeric foams occupy a unique structural space between dense solids and open networks, where engineered void fraction governs mechanical compliance, thermal resistance, and mass transport. Additive manufacturing now enables precise spatial control over cellular architecture, unlocking designer foam structures across applications spanning crash ...

Facile Preparation of Carbon Membranes Derived from a Fluorenyl‐Containing Polyimine for Selective Hydrogen Separation

open access: yesAdvanced Functional Materials, EarlyView.
A fluorenyl‐containing polyimine is introduced as a simple, scalable precursor for high‐performance carbon membranes. The precursor's intrinsic kinked structure enables defect‐free membrane formation with enhanced hydrogen permeance and excellent ideal selectivities for key industrial gas pairs (H2/N2, H2/CH4, and H2/CO2), offering a practical route ...
