Efficient photocatalytic reactors 3D printing: SLA fabrication and TiO hybrid materials.

Additive Manufacturing (AM) was evaluated as a promising technology for constructing photocatalytic reactors due to its inherent ability to produce complex geometries with high precision and customization. In this work, a 3D structure was designed to achieve a good light distribution inside a cylindrical batch reactor and printed using the stereolithography (SLA) technique. A hybrid material composed of a commercial photoreactive resin (Formlabs Clear V4) and the benchmark photocatalyst TiO P25 Evonik (1 wt%) was prepared and characterized by scanning electron microscopy (SEM) and rheological and mechanical methods.

Noninvasive Management after a Traumatic Anterior Knee Dislocation in a Cruciate Retaining Total Knee Arthroplasty: A Case Report.

The reported case describes a traumatic anterior knee dislocation of a previous asymptomatic knee after a posterior cruciate-retaining primary knee arthroplasty. The described patient accidentally rolled over her knee six years after the surgical intervention. Anterior traumatic dislocation after knee arthroplasty is an uncommon event often leading to prosthetic's components revision due to its associated ligament injuries.

Photocatalytic Oxidative Coupling of Benzyl Alcohol and Benzylamine for Imine Synthesis Using Immobilized CsBiBr Perovskite.

The oxidative cross-coupling of benzyl alcohol (BA) and benzylamine (BZA) is employed for the production of the corresponding imine, N-benzylidenebenzylamine (BZI), under visible light irradiation (light-emitting diodes (LE with λ = 417 nm) and mild reaction conditions. The cesium bismuth halide perovskites (CsBiBr, CBB) are synthesized by a one-step solution process as a sustainable alternative for the widely used Pb-halide perovskites. The CBB photocatalyst is immobilized on a polyethylene terephthalate (PET) structure designed explicitly for three-dimensional (3D) printing to operate in both batch and continuous modes to overcome the need for a final catalyst separation step.

Injury-induced KIF4A neural expression and its role in Schwann cell proliferation suggest a dual function for this kinesin in neural regeneration.

Contrary to the adult central nervous system, the peripheral nervous system has an intrinsic ability to regenerate that relies on the expression of regeneration-associated genes, such as some kinesin family members. Kinesins contribute to nerve regeneration through the transport of specific cargo, such as proteins and membrane components, from the cell body towards the axon periphery. We show here that KIF4A, associated with neurodevelopmental disorders and previously believed to be only expressed during development, is also expressed in the adult vertebrate nervous system and up-regulated in injured peripheral nervous system cells.
