The fabrication of high efficiency perovskite solar cells at larger scales will rely on the optimized deposition conditions of every layer using scalable methodologies. Most current perovskite devices that employ the archetypal TiO2 hole blocking layer utilise a simple air-brush approach. This approach is not scalable as it results in significant layer inhomogeneity across larger devices areas. To overcome this inherent limitation, in this work we use ultrasonic spray deposition as an alternative approach for the TiO2 deposition. Focusing on identical reaction chemistries as for air-brush, namely bis(isopropoxide)-bis(acetylacetonate) titanium (IV) based solutions, we find that under optimized conditions smooth TiO2 …

The local delivery of Cu2+ from copper-doped bioactive glass (Cu-BaG) was combined with 3D printing of polycaprolactone (PCL) scaffolds for its potent angiogenic effect in bone tissue engineering. PCL and Cu-BaG were, respectively, dissolved and dispersed in acetone to formulate a moderately homogeneous ink. The PCL/Cu-BaG scaffolds were fabricated via direct ink writing into a cold ethanol bath. The architecture of the printed scaffolds, including strut diameter, strut spacing, and porosity, were investigated and characterized. The PCL/Cu-BaG scaffolds showed a Cu-BaG content-dependent mechanical property, as the compressive Young's modulus ranged from 7 to 13 MPa at an apparent porosity of …

Human brain organoids provide opportunities to produce three-dimensional (3D) brain-like tissues for biomedical research and translational drug discovery, toxicology, and tissue replacement. Here we describe a protocol for rapid and defined induction of brain organoids from human induced pluripotent stem cells (iPSCs), using commercially available culture and differentiation media and a cheap, easy to handle and clinically approved semisynthetic hydrogel. Importantly, the methodology is uncomplicated, well-defined, and reliable for reproducible and scalable organoid generation, and amendable to principles of current good laboratory practice (cGLP), with the potential for prospective adaptation to current good manufacturing practice (cGMP) toward clinical compliance.
