Abstract In recent years, the use of additive manufacturing (AM) has been demonstrated in fabrication components polymer electrolyte membrane fuel cell, solid oxide cell (SOFC), microbial (MFC) and laminar flow‐based (LFFC). Various AM technologies have successfully include material extrusion, powder bed fusion, vat photopolymerization binder jetting. One unique advantages is ability to handle sophisticated design with features ranging from macro micro scales, which are inaccessible by...
Photopolymer 3D printing techniques have a common limitation: the layers to be deposited in sequential order, which constrains multi-material fabrication where vats exchanged many times, addition repeating cleaning step for each vat change. In this work, we present technique that allows stereolithography by overcoming layer-by-layer limitation, enabling one single immersion per resin. This is enabled selective crosslinking of voxels at any depth and position inside (SLA) resin vat. The...
A library of 26 electron donor-acceptor organophotocatalysts based on the benzo[ c ][1,2,5]thiadiazole (BTZ) group has been developed. These visible light were then used in a Minisci-type alkylation heteroarenes under both batch and continuous flow conditions.
Abstract The electronic industry has room for improvement in adopting cleaner strategies, both production processes (often energy-intensive and polluting) waste management. Many small components like security tags are routinely disposed of via general waste, which could be reduced biodegradable polymers. In this work, a method selective deposition metallic micro-tracks on polycaprolactone (PCL) circuitry integration is presented. polymer biodegradable, flexible, suitable 3D printing, can...
Abstract Graphene oxide (GO) induced enhancement of elastomer properties showed a great deal potential in recent years, but it is still limited by the barrier complicated synthesis processes. Stereolithography (SLA), used fabrication thermosets and very recently “flexible” polymers with elastomeric properties, presents itself as simple user-friendly method for integration GO into elastomers. In this work, was first time demonstrated that loadings can be incorporated commercial flexible...
In recent years, 3D printing has gained a great deal of attention in the energy field, with numerous reports demonstrating its application fabrication electrochemical devices. The near-complete freedom design offered by technologies make them very appealing, since complex parts can be directly fabricated. However, photochemistry and solar harvesting remains, so far, an uncharted territory. this work, photoactive monomer was incorporated into commercially available resin, which subsequently...
Photopolymer resins used in stereolithographic 3D printing are limited to penetration depths of less than 1 mm. Our approach explores the use near-infrared (NIR) visible upconversion (UC) emissions from lanthanide-based phosphors initiate photopolymer crosslinking at a much higher depth. This concept relies on invisibility windows and non-linear optical effects achieve selective photopolymers. SLA resin formulation capable absorbing light region (420–550 nm) was developed, order take...
Bright near-infrared-emitting Ag2S nanocrystals (NCs) are used for in vivo temperature sensing relying on a reversible variation intensity and photoluminescence lifetime within the physiological range. Here, to gain insights into luminescence quenching mechanisms, we investigated temperature-dependent of NCs from 300 10 K. Interestingly, both emission measurements reveal similar strong thermal 200 K, indicating an intrinsic process that limits quantum yield at room temperature, even...
A regioselective one-pot, three-step phenylation strategy has been applied to 4,7-diarylbenzo[ c ][1,2,5]thiadiazoles restrict internal bond rotation and alter the molecules' fluorescence properties.
This work presents the synergistic effect of silver (Ag) ions to enhance crosslinking 3D printing photopolymers via near-infrared (NIR) ultraviolet (UV)/visible light upconversion (UC) and allow selective metallization multi-material parts. By incorporating a commercial micron-sized ytterbium-thulium co-doped sodium yttrium fluoride phosphor (NaYF4:Yb3+, Tm3+) into photopolymer resin, low-cost NIR laser is used initiate curing exactly at focal point in depth vat, allowing voxel any space...

A method is presented to 3D print parts by photopolymer technology which enables the production of selectively plated polymer objects direct copper metallization, without sensitization. The printing with pristine and modified resins on same sample allows selective plating, paves way printed electronics. Further details can be found in article number 2201243 Jose Marques-Hueso co-workers.
Herein, a 3D printing technique to enable the manufacturing of selectively plated polymer objects by photopolymer and copper metallization is presented. Metallized plastic has become popular in number industries due its lightweight, flexibility design, cost‐effective fabrication. Common techniques require multiple pretreatment steps, such as surface etching, sensitization/activation, acceleration. The proposed method, eliminating sensitization step, allows selective 3D‐printed samples direct...
Upconversion has attracted much attention for the potential applications of nanomaterials and bulk materials. nanoprobes sensors rely on non-linear emission reporters, which present a low efficiency due to their anti-Stokes nature. For these two reasons, materials require accurate contrastable measurements, typically by measuring absolute upconversion quantum yield (UCQY). The methodology such measurements will vary from traditional photoluminescence techniques that have been applied...
