Calcium single atom catalyst with unusual activity and stability for the synthesis of dimethyl carbonate.
J Colloid Interface Sci
August 2025
Solid base catalysts with strong basicity are highly desirable for various reactions because of their minimal corrosion, ease of separation, and environmental sustainability. Nevertheless, their broader application is hindered by issues including mediocre activity and poor stability. Herein, aiming at enhancing the catalytic performance and stability of conventional solid bases, we designed and fabricated calcium (Ca) single-atom solid bases on zeolite imidazolate framework (ZIF-8) derived N-doped carbon (NPC) with Ca-N motifs as the active center for transesterification of methanol and ethylene carbonate.

- The study compares the short-term outcomes of robotic-assisted natural orifice specimen extraction (NOSES) and transabdominal specimen extraction (TRSE) in patients undergoing median rectal cancer surgery, noting advancements in minimally invasive techniques.
- Data from 87 patients were analyzed, revealing that those in the NOSES group experienced shorter surgery times, faster recovery of gastrointestinal function, and less post-surgical pain, with no wound complications reported.
- Overall, both NOSES and TRSE showed similar effectiveness for treatment, but NOSES demonstrated advantages in recovery and fewer complications, suggesting it is a safe alternative for specimen extraction in this type of surgery.
Article Synopsis
- Surgery is evolving with advances in technology, leading to minimally invasive techniques like Natural Orifice Specimen Extraction Surgery (NOSES), which is becoming increasingly popular worldwide.
- A study compared short-term outcomes of robotic-assisted NOSES and laparoscopic-assisted NOSES in 46 patients with middle rectal cancer, finding no major differences in clinicopathological data.
- Results showed that the robotic group experienced less blood loss, reduced postoperative complications, shorter recovery times, and better anal function compared to the laparoscopic group, indicating robotic assistance may enhance outcomes in NOSES procedures.
Using the paired correlation equation g(r) in the spatial point patterns, we investigated the regeneration characteristics and spatial patterns of Castanopsis hystrix seedlings and the spatial correlation with the seed trees in the plantation by large diameter wood cultivation in south subtropical China. The results showed that natural seedling regeneration in C. hystrix plantation was good, which were widely distributed in the whole plantation.

Methods: Medline, PubMed, CENTRAL, and Google Scholar databases were searched up to June 2015, using the key words cervical discectomy; bone transplantation; titanium cages; and iliac crest autografts. Outcomes of interbody fusion rates were compared using odds ratios (ORs) with 95% confidence intervals (CIs).
Objectives: To evaluate the biomechanical characteristics of endplate-conformed cervical cages by finite element method (FEM) analysis and cadaver study.
Methods: Twelve specimens (C2 -C7 ) and a finite element model (C3 -C7 ) were subjected to biomechanical evaluations. In the cadaver study, specimens were randomly assigned to intact (I), endplate-conformed (C) and non-conformed (N) groups with C4-5 discs as the treated segments.
