Linear model based on neighborhood ABS index for graph energy in benzenoid hydrocarbons and maximum index cactus graphs
We examine the sharp upper bound on the NABS index of a cactus with q vertices and l cycles in this section.
The cactus graph with q vertices and l cycles is represented as \(\mathfrak {C}^0(q,l)\), whereas the set with q vertices and t pendent…

Synthesis and properties of carbon quantum dots as an antimicrobial agent and detection of ciprofloxacin
Characterization of N-CQDs
The N-CQDs were fabricated through a single-step hydrothermal synthesis approach. The morphology, functional groups, and surface composition of the N-CQDs were systematically characterized using FTIR, TEM, XPS and XRD….

Molecular self-assembly mediates the flocculation activity of benzimidazole derivatives against E. coli
Derivatives synthesis and assessment of flocculation efficiency
Structures 1–5 were synthesised through a two-step procedure27 (Fig. 2). First, the corresponding bisbenzaldehyde was prepared by treating the corresponding α,ω-dibromoalkane…

Innovative self-assembled silver nanoparticles on reduced graphene oxide hydrogel nanocomposite for improved electrochemical hydrogen generation and sensing
Characterization of GO and rGO
The XRD pattern was analysed for a qualitative assessment of the as-prepared GO and rGO Fig. 1(a). GO displays a distinct peak at 8.5°, attributable to the (001) diffraction peaks of GO, resulting from the presence…

Nanomechanical interlocking mechanism of 10-MDP nanolayering
In this original study, we achieved the highest resolution and magnification to date for Ca-MDP nanolayering, aiming to investigating its (non)crystalline nature, resolving its atomic structure and ultrastructural atomic-scale features that may…

Machine learning based optimization of titanium electropolishing using artificial neural networks and Taguchi design in eco-friendly electrolytes
ANN modeling
The number of nodes and the configuration of hidden layers directly influence the learning capacity, performance and computational efficiency of ANNs. In particular, increasing the number of nodes and hidden layers enhances an ANN’s…

How the extraordinary science of everyday items is bringing chemistry to the public | News
If you could take a molecular-level look at anything at all, what would you choose? Your favourite food? A bird feather? Or maybe even a dinosaur fossil?
Techniques like electron microscopy and mass spectrometry are usually the preserve of…

Researchers synthesise elusive methanetetrol molecule by simulating interstellar conditions in the laboratory
For the first time, researchers have synthesised and characterised the ‘only possible structure’ with four hydroxyl groups linked to a carbon atom – methanetetrol.
Also known as orthocarbonic acid, this molecule was first hypothesised…
