Enhancing Carrier Mobility in Monolayer MoS Transistors with Process-Induced Strain.

Two-dimensional electronic materials are a promising candidate for beyond-silicon electronics due to their favorable size scaling of electronic performance. However, a major challenge is the heterogeneous integration of 2D materials with CMOS processes while maintaining their excellent properties. In particular, there is a knowledge gap in how thin film deposition and processes interact with 2D materials to alter their strain and doping, both of which have a drastic impact on device properties.

Stretchable Thin-Film Transistors Based on Wrinkled Graphene and MoS Heterostructures.

Two-dimensional (2D) materials are outstanding candidates for stretchable electronics, but a significant challenge is their heterogeneous integration into stretchable geometries on soft substrates. Here, we demonstrate a strategy for stretchable thin film transistors (2D S-TFT) based on wrinkled heterostructures on elastomer substrates where 2D materials formed the gate, source, drain, and channel and characterized them with Raman spectroscopy and transport measurements. The 2D S-TFTs had initial mobility of 4.

ZIF-8@GMP-Tb nanocomplex for ratiometric fluorescent detection of alkaline phosphatase activity.

Luminescent metal-organic frameworks (LMOFs) and their functional materials with unique characteristics can provide the basis for the construction of new analytical techniques, which can meet the continuous demand for various fields. In this work, guanosine monophosphate (GMP), terbium ion (Tb) and zeolitic imidazolate framework-8 (ZIF-8) are self-assembled to form a ZIF-8@GMP-Tb nanocomplex, which can be utilized as a ratiometric fluorescent probe to monitor alkaline phosphatase (ALP) activity. Specifically, with adding ALP, the fluorescence intensity at 547 nm (one of the characteristic emission peaks of Tb) obviously decreased.

[Epidemiology of unpleasant experiences in conscious critically ill patients during intensive care unit stay].

Objective: To survey the incidences of psychological and physiological unpleasant experiences in conscious critically ill patients during their intensive care unit (ICU) stay, and investigate the inducing factors.

Methods: A two-month consecutive nationwide investigation was prospectively performed in 31 academic hospital ICUs. An in-person questionnaire interview to each conscious patient was performed by specific trained staff from RMC-ROMIT Healthcare Consulting Company within 2 days after the patient was transferred from ICU.

[Prospective, multi-center investigation on safety of critical patients in intensive care units].

Objective: To perform a prospective, multi-center investigation of the incidence and causes of medical errors happened in intensive care unit (ICU).

Methods: This investigation was performed in eight ICUs in level A, grade 3 teaching hospitals from October 23 to December 23, 2006. One attending physician and the head nurse in each center were entrusted with the responsibility for this project.
