Summary: This study investigates the impact of HTC on the properties of waste straw fuel and the combustion kinetics of waste straw hydrochars. The results show that temperature has a greater influence on the yields of hydrochars than residence time, with different decomposition patterns observed at different temperatures. The study of the transient HTC period determines the exothermal activity of the waste straw with a heat release of 254.9 kJ/kg. The lower heating values of the hydrochars increase with higher HTC temperatures. The combustion kinetics of the hydrochars are modeled using Fraser-Suzuki deconvolution and nth-order Arrhenius equation fitting, with high R2 values.

Summary: Clean pretreatments such as washing or hydrothermal carbonization can mitigate the problems of slagging, fouling, and fuel segregation in the co-combustion of wheat straw and coal. Water washing can remove most of the potassium and phosphorus, reducing the risk of slagging and fouling. Hydrothermal carbonization can increase the heating value of wheat straw and remove organically-bonded calcium and magnesium. Hydrochars have a higher potassium retention rate and specific surface area. Hydrochars produced at 200 and 220 degrees Celsius show the optimal performance.

Summary: Hydrothermal carbonization improves the biomass quality and energy yield of rape straw. The properties of hydrochars produced at different temperatures and residence times were investigated. The results showed that increasing temperature had a more significant effect on hydrochar properties than residence time. The hydrochar structure was changed and became more stable after the aromatization reaction. The gasification reactivity of hydrochar was also affected, with the peak of pyrolysis and gasification shifting to a higher temperature region. Furthermore, hydrothermal carbonization efficiently reduced the content of alkali and alkaline earth metals, with the best removal condition observed at 200°C.

Summary: The use of straw biomass for energy can reduce the use of fossil energy and alleviate air pollution. The cohydrothermal carbonization (Co-HTC) of rice straw and wheat straw with corn straw is investigated, and synergistic effects of multistraw biomass are observed in the Co-HTC process. When the corn straw ratio is 75%, the energetic recovery efficiency, C content, and heating value increase compared to the calculated values of the Co-HTC products. The positive synergistic effect is probably caused by the enhanced dehydration and decarboxylation reactions. For the combustion behavior analysis, the entire combustion process is divided into two stages. When the corn straw ratio is greater than 50%, the comprehensive combustibility index and activation energy of stage I increase and the activation energy of stage II decreases at 180 °C, while the activation energy of stage I decreases and the activation energy of stage II increases at 260 °C. These findings demonstrate that the Co-HTC of multistraw biomass is suitable for solid biofuel production.

Summary: This study applied hydrothermal carbonization (HTC) to anaerobic digestate from cow manure, converting it into hydrochar (HC) with different characteristics at varying temperatures. The results showed that increasing HTC temperatures led to higher fixed carbon content, ash content, and calorific value of the HC, while reducing the hydrogen and oxygen content. The study also identified five major components in the HC and analyzed their combustion kinetics.

Summary: A kinetic approach combining the generalized logistic mixture model (GLMM) and the distributed activation energy model (DAEM) was proposed to explore the kinetic mechanisms of lignocellulosic biomass pyrolysis. The pyrolysis process of wheat straw could be effectively deconvoluted into three sub-processes by the GLMM, corresponding to the thermal decomposition of pseudo-hemicellulose, pseudo-cellulose, and pseudo-lignin, respectively. The GLMM and DAEM provided a methodological guideline to obtain detailed reactivity distributions involved in biomass pyrolysis, facilitating the optimization of biomass pyrolysis processes for biofuel production.

Summary: This study investigates the influence of carbonaceous aerosols on the extraction of organic carbon (OC) and black carbon (BC) in the Tibetan Plateau (TP). The results show that carbonaceous aerosols from different sources can affect the extraction efficiency of OC, leading to a reduction in the overestimation of BC concentrations. After considering this effect, actual BC concentrations at different sites on the TP were found to be lower than previously estimated, suggesting a lower warming effect caused by BC in this region.

Summary: This study investigates the comprehensive potential vorticity (PV) budget over the Tibetan Plateau (TP) and reveals the important role of diabatic heating, friction, gravity wave drag, advection, and convection in determining the circulation patterns over the TP. Diabatic heating generates positive and negative PV tendencies in summer, leading to cyclonic and anticyclonic circulation near the surface and the middle troposphere. The upward transportation of diabatic heating-generated low PV in the middle troposphere induces low PV in the upper troposphere, which is associated with the Asian monsoon anticyclone and monsoonal overturning circulation. Horizontal advection further spreads the low PV from the middle troposphere to a wide area around the TP in the upper troposphere. In winter, the diabatic heating-generated positive PV near the surface is balanced by sinking motion-carried low PV. Additionally, gravity wave drag-generated PV plays a significant role in the upper troposphere in winter and can impact downstream climate through advection. The diurnal cycle plays a crucial role in shaping the near-surface cyclonic circulation in summer by regulating the vertical structure of diabatic heating.

Summary: This study found that high expression of ubiquitin-specific protease 1 (USP1) is correlated with poor prognosis in patients with relapsed and refractory diffuse large B-cell lymphoma (DLBCL). Knocking down or inhibiting USP1 can suppress cell growth, induce cell cycle arrest, and promote autophagy in DLBCL cells. Targeting USP1 can significantly reduce tumor burden in mouse and patient-derived xenograft (PDX) models of DLBCL. USP1 interacts with the MYC binding protein MAX and maintains its stability through deubiquitination, which promotes the transcription of MYC target genes. Additionally, the drug pimozide shows synergistic effects with the chemotherapy drug etoposide in models of rituximab/chemotherapy resistant DLBCL.
