“…Notably, the contents of RN in hydrochars produced at 200 °C and 280 °C were 6.87 ± 0.12 mg/g and 6.82 ± 0.15 mg/g, respectively, higher than those in raw SM feedstock (4.99 ± 0.03 mg/g). These results are probably due to the typical Maillard reaction of proteins and amino acids with reducing sugars or their derivatives during the HTC process, which was conducive to the binding of N to aromatic rings, such as pyridine-N and quaternary-N [ 62 ]. At a low reaction temperature (200 °C), the Maillard reaction was enhanced due to the abundance of sugar and protein, and the content of quaternary ammonium salt-N in the hydrochar was higher, leading to the increase in RN in hydrochar [ 57 ].…”

Hydrothermal carbonization (HTC) has been proved to be a promising technology for swine manure (SM) treatment. Currently, there is a lack of systematic understanding of the transformation characteristics of nutrient speciation in the HTC of SM. In this study, the speciation of the main nutrients (N/P/K) in SM-derived hydrochar produced at different reaction temperatures (200–280 °C) was investigated. The recovery of P (61.0–67.1%) in hydrochars was significantly higher than that of N (23.0–39.8%) and K (25.5–30.0%), and the increase in reaction temperature promoted the recovery of P and reduced the recovery of N. After the HTC treatment, the percentage of soluble/available P was reduced from 61.6% in raw SM to 4.0–23.9% in hydrochars, while that of moderately labile/slow-release P was improved from 29.2% in raw SM feedstock to 65.5–82.7%. An obvious reduction was also found in the amounts of available N (from 51.3% in raw SM feedstock to 33.0–40.5% in hydrochars). The percentages of slow-release N and residual N in hydrochars produced at 240 °C reached the maximum and minimum values (46.4% and 18.9%), respectively. A total of 49.5–58.3% of K retained in hydrochars was residual (invalid) potassium. From the perspective of the mobility and availability of N, P and K only, it was suggested that the HTC of SM should be carried out at 220–240 °C. Compared with the original SM, it is safer and more effective to use the SM-derived hydrochar as an organic fertilizer.

“…For example, microporous organic polymers generally show a very high char yield when carbonized [99][100][101][102], a strong requirement for the formation of matrices during carbonization. Different types of other materials with fibrous or hierarchical structures or from natural sources also facilitate the synthesis of matrices [103][104][105][106][107]. Silica (SiO2) is a good starting point for biocompatible materials, it has also been used extensively as a structural template for the preparation of hybrid imaging agents [94,95].…”

Recent Progress on Molecular Photoacoustic Imaging with Carbon-Based Nanocomposites

For biomedical imaging, the interest in noninvasive imaging methods is ever increasing. Among many modalities, photoacoustic imaging (PAI), which is a combination of optical and ultrasound imaging techniques, has received attention because of its unique advantages such as high spatial resolution, deep penetration, and safety. Incorporation of exogenous imaging agents further amplifies the effective value of PAI, since they can deliver other specified functions in addition to imaging. For these agents, carbon-based materials can show a large specific surface area and interesting optoelectronic properties, which increase their effectiveness and have proved their potential in providing a theragnostic platform (diagnosis + therapy) that is essential for clinical use. In this review, we introduce the current state of the PAI modality, address recent progress on PAI imaging that takes advantage of carbon-based agents, and offer a future perspective on advanced PAI systems using carbon-based agents.

Dairy manure contains high concentrations of unutilized phosphorus which is not only a waste of resources but also a burden to dairy farmers and a threat to our environment. Phosphorus cycling and reuse would have a great impact on the dairy industry and agricultural economy as whole. Hydrochar possesses better biological properties when used for soil improvement and carbon sequestration. When produced from dairy manure, hydrochar can attain more than 90% of the total phosphorus content in manure and thus serves as an efficient vehicle for recycling nutrients from waste streams back to the crop system. Research findings prove that hydrochar from dairy manure is scientifically feasible and technologically promising as a vehicle for phosphorus recycling from waste to cropland.
