Published: April 2022

An unusual crystal phase transition was demonstrated in a zeolitic imidazolate framework with a rigid coordination network. Differential scanning calorimetry and powder X-ray diffraction revealed that nanosizing the crystal structure was crucial for the phase transition at low temperature. The thermodynamic parameters of the phase transition were determined by calorimetry.

Titanium disulfide quantum dots (TiSQDs) has garnered significant research interest due to its distinctive electronic and optical properties. However, the effectiveness of TiSQDs in electromagnetic interference (EMI) shielding is influenced by various factors, including their size, morphology, monodispersity, tunable bandgap, Stokes shift and interfacial effects. In this study, we propose a systematic approach for the synthesis of TiSQDs with small size (3.

The intentional manipulation of carrier characteristics serves as a fundamental principle underlying various energy-related and optoelectronic semiconductor technologies. However, achieving switchable and reversible control of the polarity within a single material to design optimized devices remains a significant challenge. Herein, we successfully achieved dramatic reversible p-n switching during the semiconductor‒semiconductor phase transition in BiI via pressure, accompanied by a substantial improvement in their photoelectric properties.

Cancer immunotherapy using engineered cytotoxic effector cells has demonstrated significant potential. The limited spatial complexity of existing models, however, poses a challenge to mechanistic studies attempting to approve existing approaches of effector cell-mediated cytotoxicity within a three-dimensional, solid tumor-like environment. To gain additional experimental control, we developed an approach for constructing three-dimensional (3D) culture models using smart polymers that form temperature responsive hydrogels.

Silver chalcogenides exhibit exceptional transport properties but face structural instability at high temperatures, limiting their practical applications. Using AgTe as a model, it is confirm that silver whisker growth above the phase transition renders AgTe unsuitable for thermoelectric applications. Here, the whisker growth mechanism is investigated and propose an inhibition strategy, overcoming a major obstacle in using silver chalcogenides.
