In this work we present the results of the cognitive impact evaluation regarding the use of Audiopolis, an audio and/or haptic-based videogame. The software has been designed, developed and evaluated for the purpose of developing orientation and mobility (O&M) skills in blind users. The videogame was evaluated through cognitive tasks performed by a sample of 12 learners. The results demonstrated that the use of Audiopolis had a positive impact on the development and use of O&M skills in school-aged blind learners.

The monolayer transistor, where the semiconductor layer is a single molecular layer, offers an ideal platform for exploring transport mechanisms both theoretically and experimentally by eliminating the influence of spatially correlated microstructure. However, the structure-property relations in polymer monolayers remain poorly understood, leading to low transistor performance to date. Herein, a self-confinement effect is demonstrated in the polymer monolayer with nanofibrillar microstructures and edge-on orientation, as characterized by the 4D scanning confocal electron diffraction method.

The quest for sustainable and clean energy sources has led to significant research into photocatalytic water splitting, a process that converts solar energy into hydrogen fuel. This study demonstrates constructing a high-performance CdTe/CN van der Waals heterojunction for solar-driven water splitting hydrogen evolution. The proposed CdTe/CN heterojunction, investigated using first-principles calculations, integrates favorable structural stability and features a direct bandgap of 1.

The gas-phase structures of dibenzo-24-crown-8 (DB24C8) and dinaphtho-24-crown-8 (DN24C8) complexes with divalent metal ions (Mg, Ca, Sr, Ba, Fe, Ni, and Zn) were investigated by cryogenic ion mobility-mass spectrometry (IM-MS) in combination with density functional theory calculations. Several complexes, particularly those of DN24C8, exhibited multiple coexisting conformers. DFT-optimized structures were classified based on the relative orientation of the two aromatic rings in the crown ether.

The orientation of MXene flakes has received increasing research attention as it plays a critical role in determining the performance of MXene-based assemblies. Engineering MXene flakes into horizontal or vertical orientations can offer distinct advantages such as higher electrical conductivity, higher mechanical strength, and more efficient ion/molecule transport across the flakes. However, the benefits of horizontal and vertical orientations are mutually exclusive, and both of them possess structural symmetry that restricts their ability for stimuli-responsive deformation.

Developing efficient and durable catalysts for the oxygen evolution reaction (OER) in acidic media is essential for advancing proton exchange membrane water electrolysis (PEMWE). However, catalyst instability caused by lattice oxygen (O) depletion and metal dissolution remains a critical barrier. Here, we propose an oxophilic-site-mediated dynamic oxygen replenishment mechanism (DORM), in which O actively participates in O-O bond formation and is continuously refilled by water-derived species.
