Layer-by-Layer Growth of Two-Dimensional Tellurium Thin Films via Ultrahigh-Pressure Atomic Layer Deposition for -Type Semiconductors.

Tellurium (Te) has emerged as a prominent candidate among two-dimensional materials due to its impressive properties, such as high mobility, stability, and compatibility with low-temperature processing. However, achieving consistent uniformity over large areas for ultrathin Te films deposited at low temperatures has remained a substantial challenge. Atomic layer deposition (ALD) has been proposed as a promising solution, offering precise thickness control and highly conformal thin film deposition even at low temperatures.

Processes to enable hysteresis-free operation of ultrathin ALD Te p-channel field-effect transistors.

Recently, tellurium (Te) has been proposed as a promising p-type material; however, even the state-of-the-art results couldn't overcome the critical roadblocks for its practical applications, such as large - hysteresis and high off-state leakage current. We developed a novel Te atomic layer deposition (ALD) process combined with a TeO seed layer and AlO passivation to detour the limitations of p-type Te semiconducting materials. Also, we have identified the origins of high hysteresis and off current using the 77 K operation study and passivation process optimization.

Favorable outcome of a histiocytic sarcoma patient treated with immune checkpoint inhibitor: a case report.

Introduction And Importance: Histiocytic sarcoma (HS) is an extremely rare malignancy in which there has been no standard treatment approach. Some preclinical studies have provided rationales for the application of immunotherapy in advanced HS.

Case Presentation: The authors reported a case of a 61-year-old patient with metastatic HS who had a rapid progression on ifosfamide, carboplatin, and etoposide chemotherapy.

Systemic chemotherapy combined with radiofrequency ablation for colorectal cancer with liver metastasis: a retrospective cohort study.

Unlabelled: This study aims to evaluate the efficacy of systemic chemotherapy combined with radiofrequency ablation in the treatment of inoperable colorectal cancer with liver metastasis.

Materials And Methods: The authors conducted a retrospective cohort analysis on 30 patients diagnosed as colorectal cancer with liver metastasis who underwent systemic chemotherapy combined with radiofrequency ablation of the liver lesions from January 2017 to August 2020 at our institution. Responses was evaluated by International Working Group on Image-guided Tumor Ablation criteria, along with progression-free survival.

Impact of the Covid-19 pandemic on perceptions and behaviors of university students in Vietnam.

This article presents a novel data set on perceptions and behaviors of university students collected after the beginning of the Covid-19 outbreak in Vietnam. Our questionnaire design is based on employing both qualitative interview with students and survey of SARS literature, probing into the sensitivity of students toward the crisis in making crucial decisions of daily routines, as well as future travel plans in presence of a grave health concern. The data set consists of 440 valid responses from Vietnamese university students through Internet platforms (Facebook, Google Form).
