A facile, one-pot synthesis of N-succinimidyl-4-[18F]fluorobenzoate ([18F]SFB) was developed based on a non-aqueous, three-step radiochemical process. Using microwave heating, the entire procedure can be completed in less than 30 min, or 60 min with further purification by preparative HPLC. The decay-corrected radiochemical yields (RCYs) were 35-5% (n > 30).

CO2 transformations are conducted in a one-pot two-step procedure for the synthesis of complex molecules. The selective 4 e- reduction of CO2 with a hydroborane reductant affords a reactive and versatile bis(boryl)acetal intermediate which is subsequently involved in condensation reaction or carbene-mediated C-C coupling generation.

A 2-azido-1-nitrate-ester can be converted to the corresponding 2-azido-1-trichloroacetimidate in a one-pot procedure. The goal of the manuscript is to demonstrate utility of the microwave reactor in carbohydrate synthesis.
FAQs
During curing, the initiator drives the conversion of liquid methyl methacrylate monomer into a rigid PMMA matrix around the embedded material. This transition immobilizes the specimen or device, allowing its position relative to surrounding tissue and implant surfaces to remain stable. The resulting support is important when later examination requires sectioning, imaging, or mechanical testing.
Controlled temperature and curing conditions are central because polymerization can produce heat-related changes in the embedded material. Managing these conditions helps maintain the characteristics being investigated rather than introducing alterations during preparation. In medical specimens, that preservation supports more reliable assessment of bone structure, tissue integration, or damage at an implant interface.
Potting is especially useful when the relationship between multiple components matters. A cured block holds undecalcified bone, an implant, and adjacent tissue in their spatial arrangement, so investigators can examine the interface rather than isolated parts. This context helps connect microscopic or imaging findings with fixation quality and the structural condition of the device.
The rigid matrix provides mechanical support during downstream handling and analysis. By restraining the embedded material, it can maintain spatial relationships while investigators perform microscopy, imaging, or mechanical testing. This is particularly relevant for orthopedic research, where conclusions about fixation, wear, or structural damage depend on examining the implant and surrounding tissue together.
Preparation begins with liquid methyl methacrylate monomer, which is mixed with a polymerization initiator before the material is embedded. The assembly is then cured under controlled temperature and curing conditions until the resin forms a rigid block. Subsequent handling can include sectioning followed by microscopy, imaging, or mechanical testing, depending on the study objective.
Researchers apply this approach to undecalcified bone, bone-implant interfaces, and orthopedic devices. It is selected when the study needs the embedded material stabilized without losing the relationship among tissue, bone, and implant. These applications support pathology, biomaterials research, and implant evaluation, including investigations of fixation, tissue integration, wear, and structural damage.
Results can show whether tissue has integrated with an implant, how well the implant is fixed, and where wear or structural damage occurs. Microscopy and imaging provide views of preserved relationships, while mechanical testing adds information about performance under test conditions. Together, these outcomes help characterize both biological response and device condition in orthopedic investigations.
