Asymmetric rotations slow down diffusion under confinement.

Translation and rotation are the two most fundamental forms of diffusion, yet their coupling mechanism is not clear, especially under confinement. Here, we provided evidence of the coupling between rotation and translation using a substituted benzene molecule as an example. A counterintuitive behavior was observed where the movement of the smaller molecule with an asymmetric shape was unexpectedly slower than the larger one with a symmetric shape in confined channels of zeolite.

Significance of non-steroidal anti-inflammatory drugs in the prevention and treatment of cervical cancer.

Cervical cancer, ranking as the fourth most common cancer in women globally, is closely linked to chronic inflammation resulting from persistent human papillomavirus (HPV) infection. Chronic inflammation mediated by cyclooxygenase (COX) has been identified as a factor in cancer onset and progression, with HPV oncoproteins E6 and E7 inducing COX activation. Nonsteroidal anti-inflammatory drugs (NSAIDs) have demonstrated the capability to significantly inhibit COX activity, playing a crucial preventive and therapeutic role in various tumors.

Chromosome balanced translocation in newborn fetus founded during prenatal diagnosis: Three cases reports.

Rationale: Because of the normal phenotype, carriers of specific chromosomal translocations are often diagnosed only after their development of associated malignancies, recurrent miscarriages, and reproductive difficulties. In this paper, we report primary balanced fetal chromosomal translocations by performing the necessary invasive prenatal diagnosis in couples with previous malformations coupled with prenatal testing suggesting a high risk for trisomy 21.

Patient Concerns: Case 1 and Case 2 couples had malformed children, and Case 3 couples had a high risk of trisomy 21 on noninvasive preconception serological testing.

Gas-template directed synthesis of highly nitrogen-doped carbon nanotubes with superior sulfur compatibility and enhanced functionalities.

Herein, we develop a low temperature gas template route for growth of highly nitrogen-doped (5.68 wt%), multi-walled carbon nanotubes (N-MWCNTs). The N-MWCNTs exhibit superior sulfur compatibility in hydrogen sulfide (HS) resource utilization, thus resulting in their enhanced functionality as Li-S cathodes with high sulfur-specific capacity and retention rate.

Stable Porous Organic Polymers Used for Reversible Adsorption and Efficient Separation of Trace SO.

The development of porous solid adsorbents for selective adsorption and separation of SO has attracted much attention recently. Herein, we design porous organic polymers (POPs) decorated with pyridine ligands as building units (POP-Py) through a radical polymerization of the 2,5-divinylpyridine (v-Py) monomer. Due to its high BET surface area, nanoporosity, and excellent stability, the prepared POP-Py can be used for reversible adsorption and efficient separation of SO.

Sustainable synthesis of ordered mesoporous materials without additional solvents.

Micelles with well-defined nanostructures were generally formed in the presence of a suitable solvent. We report herein the accelerated construction of micelles with ordered nanostructures without assistance of additional solvents. The micelles were employed for ultrafast fabrication of ordered mesoporous silicas (OMS) using tetramethyl orthosilicate (TMOS) as silica source.

Efficiently Selective Oxidation of HS to Elemental Sulfur over Covalent Triazine Framework Catalysts.

As a highly toxic and corrosive waste gas in the industry, hydrogen sulfide (HS) usually originates from the utilization of coal, petroleum, and natural gas. The selective catalytic elimination of HS shows great significance to ensure the safety of industrial processes and health of human beings. Herein, we report efficiently selective oxidation of HS to elemental sulfur over covalent triazine framework (CTF-1-, = 400, 500, 600, 400-600 °C) catalysts.
