N-piperidinyl substituted trioxotriangulene as an efficient catalyst for oxygen reduction reaction in fuel cell application-a DFT study

Thangaraj Thiruppathiraja et al.

Summary: In this study, a N-piperidinyl-substituted trioxotriangulene (TOT) surface was constructed as a catalyst for both 2e(-) and 4e(-) pathways of the oxygen reduction reaction (ORR). Density functional theory (DFT) was used to investigate the ORR at two active sites, the O site (oxygen) and N site (nitrogen) on the N-piperidinyl-substituted TOT surface. Reactants and intermediates adsorbate chemisorb, while the product physisorbs. The results showed that the O site exhibits strong catalysis for both 2e(-) and 4e(-) pathways, and the associative mechanism in the 4e(-) pathway has low overpotential at the O-active site. These findings suggest that the N-pipeTOT surface is a potential catalyst for fuel cell applications.

Catalytic activity of OH functionalized N-doped graphene in oxygen reduction reaction for fuel cell applications: a DFT study

Thangaraj Thiruppathiraja et al.

Summary: The catalytic behavior of metal-free hydroxyl group (OH) functionalized single nitrogen (N-Gra(OH)(16)) and triple nitrogen (N-3-Gra(OH)(16)) doped graphene surface in the 4e(-) reduction pathway under oxygen reduction reaction (ORR) process has been studied. The thermodynamic parameters indicate that the reaction is highly exothermic and feasible with N-Gra(OH)(16) and N-3-Gra(OH)(16) as catalysts. N-3-Gra(OH)(16) exhibits better catalytic properties and is the most suitable catalyst for ORR activity.

Multi-stimuli responsiveness of pyrimidine bishydrazone: AIE, tuneable luminescence, white light emission, mechanochromism, acidochromism and its anticounterfeiting applications

Ottoor Anitha et al.

Summary: The development of multifunctional properties associated with a single molecule has gained significant attention in recent material science research. An aggregation-induced emissive (AIE) molecule with stimuli-responsiveness such as mechanochromism, acidochromism, and white-light emitting behavior holds great potential for various applications. In this study, a D-A-D triad-based AIE active organic molecule HYPY-DESAL was designed through a facile one-step Schiff-base condensation reaction and demonstrated white light emission and tunable emission characteristics, making it suitable for light emitting diode applications. The molecule also exhibited exceptional solid-state stimuli responsiveness and was successfully used for coding-decoding, information storage, and anti-counterfeiting applications in paper strips and PMMA-based thin films. The combined features of this molecule, including AIE, tuneable luminescence, white light emission, mechanochromism, acidochromism, and vapor phase sensing, make it unique and potentially unprecedented.

Real time sensor for Fe3+, Al3+, Cu2+ & PPi through quadruple mechanistic pathways using a novel dipodal quinoline-based molecular probe

Sagarika Mishra et al.

Summary: A quinoline-based small molecular probe, H2L, was designed, synthesized, and characterized for the detection of Fe3+, Al3+, Cu2+, and PPi. The probe exhibited selective instant turn-on fluorimetric response towards Fe3+ and Al3+, and sequential turnoff response towards PPi in H2L solutions containing Fe3+ or Al3+. It also showed a sharp color change in the presence of Cu2+, and its potential as a colorimetric sensor for Cu2+ was confirmed through UV-Vis studies. The practical utility of the proposed sensor was demonstrated through filter-paper strip experiments, and the potential application of H2L as a pH sensor in the acidic range was explored.

A novel phenolphthalein-based fluorescent chemosensor for pyrophosphate detection via an Al3+ displacement approach in real samples and living cells

Xiang-Yu Kong et al.

Summary: In this study, a new phenolphthalein-appended Schiff base (PASB) was reported as a reversible fluorescent sensor for the detection of pyrophosphate (PPi) ions and aluminum ions (Al3+) through the metal displacement mechanism. PASB exhibited selective sensing of Al3+ ions and showed significant fluorescence enhancement. The binding stoichiometry between PASB and Al3+ was confirmed, and a high selectivity for PPi was observed. The addition of PPi quenched the fluorescence of the PASB-Al3+ complex, leading to a dual response for detecting both Al3+ and PPi. The detection limits for Al3+ and PPi were 5.86 nM and 26 nM, respectively. Additionally, PASB was successfully used to detect Al3+ in food samples and for intracellular imaging in human liver cancer cells.
