This review article deeply focuses on the use of heteroatom-doped nanomaterials and core–shell nanostructures for various kinds of fuel cell and battery applications.

Greener methods for the extraction and isolation of tannin, and it's state of art in adhesive technology.

A co-assembling system composed of a nonchiral metal-free dye and chiral-molecular-assembly template can be a promising candidate for circularly-polarized luminescent materials with both a high luminescence dissymmetry factor and strong emission.

We have found that the electrical properties of an organic charge transfer salt are qualitatively affected by slight differences in the conformation of one of the ethylene groups, which is not involved in the conduction pathways.

The effect of the Al³⁺–Mg²⁺ cosubstituent ratio on the optoelectronic, surface, and photocatalytic properties of BaTaO₂N is studied.

To achieve a 20 Gbps data rate using the upcoming 5G communication standard, it is crucial to recognize a domain wall (DW) velocity (v_DW) of 1200 m s⁻¹.

Light driven crystal actuators, where bending direction and speed are controlled by crystal thickness and light wavelength, are fabricated.

In this study, a new type of single-molecule white luminescence is presented. This luminescence is accomplished by dual emission from two different stacking patterns having different overlapping areas in the crystal.

Efficient and stable flexible perovskite solar cells were fabricated with reduced residual strain by pre-applying strain on the flexible substrate. The flexible cells showed efficiencies of up to 18.7% and operational stability lifetime exceeding 700 h.

Paramagnetic ultrasmall Ho₂O₃ and Tm₂O₃ nanoparticles grafted with various hydrophilic and biocompatible ligands as a new class of efficient T₂ MRI contrast agents were investigated in this study.

Fiducial markers are crucial for reducing damage to surrounding healthy tissues in real-time image gated proton therapy (RGPT) by boosting geometric accuracy and precision.

Towards the application of perovskite solar cells (PSCs) in space, we extensively investigated the effects of electron beam irradiation on binary-mixed PSCs with various hole- and electron-transport materials.

A series of quaternized polysulfone (QPS)-based composite membranes containing various amounts of functionalized graphitic carbon nitride (f-g-C₃N₄) nanosheets were synthesized.

1-Hexanoic acid stabilised copper nanoparticles were obtained. Cu₆₄O phase could be found on the particle surface. During sintering, the stabilising molecule, 1-hexanoic acid, reduced Cu₆₄O to Cu and it introduced neckings between the particles.

A simple one-pot solution-processed OFET memory device has been fabricated based on the vertical phase separation of phthalocyanine-cored star-shaped polystyrene and an organic semiconductor.

This study provides an organic mixed ionic–electronic conductor (OMIEC) memristor based on Ru(bpy)₃(PF₆)₂ as an organic active layer to mimic the STP of a biological synapse.

A (100 − x)Li₂S·xAlI₃ (0 ≤ x ≤ 30) positive electrode was prepared by the planetary ball-milling method for application in all-solid-state Li–S batteries.
