Summary: This study successfully synthesized high-quality single-walled carbon nanotubes (SWNTs) on layered double hydroxides (LDHs) containing Fe and FeCo using CO chemical vapor deposition (CVD). The effects of temperature and catalyst composition on the diameter and chirality distributions of SWNTs were investigated. It was found that subnanometer SWNTs were produced by both catalysts at low temperatures. The (6, 5) SWNTs were synthesized from LDHs containing bimetallic FeCo at 600 degrees C, and the chirality distribution was further narrowed by a two-phase extraction method.

Summary: Trivalent gallium ions were successfully incorporated into chemically well-defined MgAl-layered double hydroxide (LDH) frameworks through postsynthetic hydrothermal treatment. The Ga3+ was first incorporated into LDH through partial dissolution-precipitation at the edge of LDH particle and homogeneously distributed throughout the particle by substitution of Ga3+ for Al3+ in LDH frameworks. The crystal structure was not affected by Ga3+ incorporation, and no unexpected impurities were observed.

Summary: A facile chemical co-precipitation method is reported for the preparation of nickel-cobalt layered double hydroxide (Ni, Co-LDH). The controlled introduction of carbonate ions (CO32-) through the addition of NaHCO3 causes the nanosheet structure to bend and inter-connect, increasing the contact area between the electrode and the electrolyte and enhancing the energy storage characteristics. Appropriate CO32- doping effectively increases the specific capacity and rate capability of Ni, Co-LDH.

Summary: Efficient and low-cost catalysts for peroxymonosulfate (PMS) activation are essential for pollution prevention and environmental remediation. In this study, biochar (BC) was composited with CoFe layered double hydroxide (CoFe-LDH) to achieve enhanced PMS activation. The synergistic effect between BC and CoFe-LDH resulted in improved catalytic activity and stability, leading to higher production of reactive oxygen species (ROS) in the BC-LDH/PMS system. The degradation efficiency of dimethyl phthalate (DMP) was significantly higher in the BC-LDH/PMS system compared to the CoFe-LDH/PMS system, reaching 100% within 60 minutes.

Summary: This study demonstrates the improved thermoelectric performance of Bi2Te3 nanosheets grown on reduced graphene oxides (rGO) through the formation of heterointerfaces. The phonon scattering effect and extra carrier transport channels induced by the rGO-Bi2Te3 heterointerface lead to an enhanced power factor value and reduced thermal conductivity. Furthermore, the photo-thermoelectric catalysis of rGO-Bi2Te3 significantly increases the yield of reactive oxygen species. This study provides new insights into heterointerface design in photo-thermoelectric catalysis.

Summary: Confering catalytic defects in sonosensitizers is crucial for enhancing sonodynamic therapy. In this study, 2D catalytic planar defects were designed within Ti3C2 sheets to overcome this challenge. These planar slip dislocations with abundant Ti3+ species can activate O-2, resulting in a significant amount of O-1(2) generation and a high bactericidal capability under ultrasound stimulation. It was found that the 2D catalytic planar defects can intervene in electron transfer through the phonon drag effect, leading to a dramatic decrease in O-2 activation energy.

Summary: A rapid and effective therapeutic strategy for treating osteomyelitis is reported, utilizing ferroelectric polarization interfacial engineering of BiFeO3/MXene (Ti3C2) triggered by ultrasound. The ferroelectric polarization induced by ultrasound leads to the formation of a piezoelectric field, and the sonoluminescence effect stimulates BiFeO3/Ti3C2 to produce photogenerated carriers. With the synergistic action of the polarization electric field and Schottky junction, the separation of electrons and holes is accelerated, improving the utilization of polarized charges and photogenerated charges, and enhancing the yield of reactive oxygen species. This approach efficiently kills Staphylococcus aureus in a short time with the assistance of ultrasonic heating.

Summary: A self-standing hybrid system Ni18Fe12Al70, composed of Ni2Al3 and Ni3Fe phases, was constructed by laser-assisted Al incorporation for full water splitting. The incorporation of Al effectively tuned the morphologies, compositions, and phases. Ni18Fe12Al70 exhibited extremely low overpotentials for both HER (eta(100)=188 mV) and OER (eta(100)=345 mV) processes and maintained a stable overpotential for 100 h, comparable to state-of-the-art electrocatalysts. The synergistic effect of Ni2Al3 and Ni3Fe alloys on the HER process was confirmed based on theoretical calculations.

Summary: Long-term sequelae clustering phenotypes play a crucial role in providing precise health care management for COVID-19 survivors. In this study, we examined 1000 survivors in China 20 months after their COVID-19 diagnosis. The results showed that generalized symptoms were most common, followed by mental, cardiopulmonary, neurological, and digestive symptoms. Four clusters were identified based on symptom patterns, ranging from no or mild symptoms to severe impairment. Factors such as physical comorbidities, history of mental disorders, longer hospitalization periods, and severe acute illness were associated with more severe symptoms. This study highlights the importance of identifying and addressing specific sequelae clusters in COVID-19 survivors for targeted recovery interventions.
