Fluorinated-PDMS enhanced single-electrode triboelectric nanogenerator for biomechanical energy harvesting and sensing applications

Abhinav Mahapatra; Deepak Deepak; Tanuja Singh et al.

APL Electronic Devices, Vol. 2 No. 1 · 2026 · English · DOAJ

Single-electrode triboelectric nanogenerators (STENGs) are promising candidates for biomechanical energy harvesting and self-powered sensing due to their simple structure and compatibility with wearable systems. However, their performance is often limited by the intrinsic tribonegativity of polymer…

Sudipta Choudhury; Deepak Deepak; Gourav Bhattacharya et al.

Macromolecular Materials and Engineering, Vol. 308 No. 8 · 2023 · English · DOAJ Scopus

Abstract Wearable pH sensors for sweat analysis have garnered significant scientific attention for the detection of early signs of many physiological diseases. In this study, a MoS2‐polyaniline (PANI) modified screen‐printed carbon electrode (SPCE) is fabricated and used as a sweat biosensor. The…

Load-Flow-Based Calculation of Initial Short-Circuit Currents for Converter-Based Power System

Deepak Deepak; Anisatur Rizqi Oetoyo; Krzysztof Rudion et al.

Energies, Vol. 18 No. 15 · 2025 · English · DOAJ Scopus

Short-circuit current is a key characteristic value for synchronous generator-based power systems. It is employed for different applications during the planning and operation phases. The proportion of converter-interfaced units is increasing in order to integrate more renewable energy sources into…

C, Vol. 9 No. 4 · 2023 · English · DOAJ Scopus

The advancement of renewable energy technologies like water electrolysis and hydrogen fuel cells relies on the fabrication of effective and reliable catalysts for the hydrogen evolution process (HER). In this regard, we report gold nanoparticles embedded in laser-induced graphene electrodes for…

Flexible laser-induced graphene (LIG)/ZnO-nanorod (NR) heterostructure for efficient photodegradation

Megha Megha; Deepak Deepak; Susanta Sinha Roy et al.

RSC Advances, Vol. 16 No. 38 · 2026 · English · DOAJ Scopus

In this work, a flexible laser-induced graphene (LIG)/ZnO nanorod heterostructure was developed for the photocatalytic degradation of methylene blue (MB) under UV exposure. Oxygen plasma treatment was employed to alter the LIG surface wettability from hydrophobic to hydrophilic, thus facilitating…

FAILURE ANALYSES OF TOWER CRANE USING FEM AND THEORETICAL STUDIES

Mofareh Hassan Ghazwani; A. H. Alnujaie; M. L. Chandravanshi et al.

Yanbu Journal of Engineering and Science, Vol. 19 No. 2 · 2022 · English · DOAJ

This paper describes the technique to explicitly increase the tower crane's stability during cyclones through modal analysis in FEM. For this, modal analyses of a boom, mast, and tower crane are carried out individually to minimize the tuning effect of natural frequencies. The study explains the…

Comprehensive study on dynamics of early embryonic development in Marwari mares

DEEPAK DEEPAK; D JHAMB; S S NIRWAN et al.

Indian Journal of Animal Sciences, Vol. 92 No. 3 · 2022 · English · DOAJ Scopus

Horse is a seasonal breeder with reproductive activity being associated with long days, i.e. occurring in spring and early summer. Early equine pregnancy shares many features with that of more intensively assessed domestic animals species, but there are also characteristic differences. In mares…
