Unveiling the Interfacial and Structural Heterogeneity of TiCT MXene Etched with CoF/HCl by Integrated Thermal Analysis.

TiCT MXene is a member of the recently discovered two-dimensional early transition metal carbide and nitride family of MXenes with potential applications in energy storage and heterogeneous catalysis at elevated temperatures. Here, we apply a suite of techniques to probe TiCT MXene's thermal evolutions, including X-ray diffraction (XRD), diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS), and integrated thermogravimetry-differential scanning calorimetry-mass spectrometry (TG-DSC-MS). In light of this set of investigations, we find heterogeneity in the layering of TiCT MXene revealed only at higher temperatures.

Analysis of perioperative factors and cost comparison of single-incision and traditional multi-incision laparoscopic cholecystectomy.

Background: Recent technological advances in single-incision platforms have allowed many general surgeons to add single-incision laparoscopic cholecystectomy (SILC) to their armamentarium. However, adopting new surgical technologies comes at a cost to the patient and the surgeon. This study compared retrospective case-matched SILC and traditional multi-incision laparoscopic cholecystectomy (MILC) to evaluate the effects of SILC on perioperative outcomes and patient cost.
