Cancer stem cells CD133 inhibition and cytotoxicity of certain 3-phenylthiazolo[3,2-a]benzimidazoles: design, direct synthesis, crystal study and in vitro biological evaluation

open access: yesJournal of Enzyme Inhibition and Medicinal Chemistry, 2017
Cancer stem cells (CSCs) have been objects of intensive study since their identification in 1994. Adopting a structural rigidification approach, a novel series of 3-phenylthiazolo[3,2-a]benzimidazoles 4a–d was designed and synthesised, in an attempt to ...

Molecular Nanoarchitectonic Sensing Layer for Analysis of Volatile Fatty Acids in Bioreactor Headspaces Using a Nanomechanical Sensor

open access: yesAdvanced Materials Technologies, EarlyView.
A porous crystalline sensing layer has been developed in conjunction with a nanomechanical sensor for the sensitive detection of volatile fatty acids (VFAs) in admixture at high relative humidity. The sensitive, selective sensor based on supramolecular design improves the economic viability of anaerobic digesters toward a carbon neutral society ...

Core/shell structured ZnO@SiO2-TTIP composite nanoparticles as an effective catalyst for the synthesis of 2-substituted benzimidazoles and benzothiazoles

open access: yesJournal of Experimental Nanoscience, 2018
ZnO@SiO2-TTIP was synthesised as a novel heterogeneous catalyst and characterised by FT-IR, XRD, TEM, SEM and N2 adsorption-desorption. In this catalytic system, TTIP acts as a dopant agent for ZnO@SiO2 to decreases the recombination of photogenerated ...

Influence of Outcoupling Layers on Top‐Emitting Perovskite Light‐Emitting Diodes

open access: yesAdvanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
Top‐emitting perovskite LEDs offer benefits over typical bottom‐emitting architectures, toward lasing, improved thermal management, and on‐chip fabrication compatibility. Outcoupling layers offer a strategy uniquely applicable to top‐emitting LEDs to optimize EQE by improving optical outcoupling.

Surfing the Color Map with Carbazole‐Appended Cyclometalated N‐Heterocyclic Carbene Pt Complexes and Their Application in Green Organic Light‐Emitting Devices

open access: yesAdvanced Optical Materials, EarlyView.
Complexes [PtII(Cbz‐C^C*bzim/im)(L^L)], bearing carbazole‐appended cyclometalated NHCs, show bright phosphorescence, peaking from the blue to the yellowish–green spectral range depending on the carbene, L^L, and doping concentration. Non‐doped OLEDs using 1A or 3A (L^L = acac or P^O2) reach the best performances (Von: 2.99 V, 2.55 V; Lmax: 39208, 25837

Curcuminoid Derivatives with a Donor‐Acceptor‐Donor Architecture: an Outstanding Platform for Highly‐Efficient Near‐Infrared Electroluminescence and Amplified Spontaneous Emission

open access: yesAdvanced Optical Materials, EarlyView.
Curcuminoid boron difluoride dyes containing triphenylamine units are prepared and their photophysical and electrochemical properties are investigated. These new light‐emitting dyes are used in organic light‐emitting diodes (OLEDs) emitting at 800 nm with 1% external quantum efficiency, and show low threshold amplified spontaneous emission in thin ...

Cation‐Engineered Post‐Treatment for Blue Perovskite Light‐Emitting Diodes

open access: yesAdvanced Optical Materials, EarlyView.
This work presents a cation‐engineered post‐treatment strategy for high‐performance mixed‐halide blue PeLEDs. By investigating the role of 4‐fluorophenylethylammonium (FPEA+) versus conventional phenylethylammonium (PEA+) organic cations in post‐treatment agents, it demonstrates that FPEA+ enables superior preservation of the 3D perovskite structure ...

Surface-enhanced Raman Spectroscopy of Benzimidazolic Fungicides: Benzimidazole and Thiabendazole [PDF]

open access: yesBulletin of the Korean Chemical Society, 2009
‡Surface-enhanced Raman Scattering (SERS) spectroscopy is applied to the study of the adsorption of benzoimidazolic fungicides benzimidazole (BIZ) and thiabendazole (TBZ) on silver mirrors. The influence of pH on the adsorption mechanism was investigated.

Impact of the Substitution Pattern in N–heterocyclic Olefin‐Substituted Phosphines on Palladium Catalysis

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
The impact of olefin backbone substitution in N‐heterocyclic olefin‐substituted phosphines is investigated. While these ligands are highly electron‐donating, their catalytic activity in Pd‐catalyzed CN cross‐coupling reactions decreases as the size of the backbone substituent increases.
