Ultrafast Dissociation Dynamics of the Sensitive Explosive Ethylene Glycol Dinitrate.

Ethylene glycol dinitrate (EGDN) is a nitrate ester explosive widely used in military ordnance and missile systems. This study investigates the decomposition dynamics of the EGDN cation using a comprehensive approach that combines femtosecond time-resolved mass spectrometry (FTRMS) experiments with electronic structure and molecular dynamics computations. We identify three distinct dissociation time scales for the metastable EGDN cation of approximately 40-60 fs, 340-450 fs, and >2 ps.

Femtosecond laser-assisted cataract surgery (FLACS) is a useful technology for anterior segment surgery that creates cleavage planes via photodisruption of ocular tissue. Compared to conventional cataract surgery, FLACS has been thought to potentially improve surgical precision, accuracy, and reproducibility. Its introduction into cataract surgery has enabled the development of new techniques and has been purported to be potentially beneficial in improving surgical safety and providing quicker visual rehabilitation.

This study aims to compare the efficacy and safety of femtosecond laser-assisted implantable collamer lens (ICL) implantation with traditional manual ICL techniques. A retrospective analysis was conducted on patients who underwent ICL implantation at Beijing New Vision Eye Hospital in 2023. Patients (aged 18-45) were matched for gender and refractive error, with forty-two eyes in each group.

Purepose: The intraoperative femtosecond laser time, Cumulative Dissipated Energy (CDE), Effective Phacoemulsification time (EPT), and intraoperative fluid perfusion volume were compared under different model fragmentation modes using Catalys femtosecond laser system.
Methods: This was a single-center, prospective, randomized controlled study. A total of 120 eyes who underwent femtosecond laser-assisted cataract phacoemulsification combined with intraocular lens implantation in Xiamen Eye Center affiliated to Xiamen University from September 2022 to March 2023 were randomly divided into 4 groups to undergo pre-nucleus splitting in different ways: Group 1: six-split, Group 2: eight-split, Group 3: six-split + gridded softening, and Group 4: eight-split + gridded softening.

The existence of residual small-size tumors after surgery is a major factor contributing to the high recurrence rate of glioblastoma (GBM). Conventional adjuvant therapeutics involving both chemotherapy and radiotherapy usually exhibit unsatisfactory efficacy and severe side effects. Recently, two-photon photodynamic therapy (TP-PDT), especially excited by the second near-infrared (NIR-II) light, offers an unprecedented opportunity to address this challenge, attributed to its combinational merits of PDT and TP excitation.
