Jiangsu Co-Innovation Center of Efficient Processing and Utilization of Forest Resources, College of Chemical Engineering, Nanjing Forestry University, Nanjing 210037, China. Electronic address:

Cellulose-based porous materials are promising for various fields and preferred for sustainable development. However, the low mechanical properties and high hydrophilicity of cellulose-based xerogels had a direct influence on their application in oil absorption. To address the challenge, an environmentally friendly and economical method for synthesizing MTMS/C0.

Background: Mixed exhaled air has been widely used to determine exhaled propofol concentrations with online analyzers, but changes in dead space proportions may lead to inaccurate assessments of critical drug concentration data. This study proposes a method to correct propofol concentration in mixed air by estimating pulmonary dead space through reconstructing volumetric capnography (Vcap) from time-CO and time-volume curves, validated with vacuum ultraviolet time-of-flight mass spectrometry (VUV-TOF MS).

Methods: Existing monitoring parameters, including time-volume and time-CO curves, were used to determine Vcap.

The respiratory control system exhibits neural plasticity, adjusting future ventilatory responses based on experience. We tested the hypothesis that ventilatory long-term facilitation induced by hypercapnic acute intermittent hypoxia (AIH) at rest enhances subsequent ventilatory responses to steady-state exercise. Fourteen healthy adults (age = 27 ± 5 years; 7 males) participated in the study.

Metal-organic frameworks (MOFs) are hybrid inorganic-organic 3D coordination polymers with metal sites and organic linkers, which are a "hot" topic in the research of sorption, separations, catalysis, sensing, and environmental remediation. In this study, we explore the molecular mechanism and kinetics of interaction of the new copper porphyrin aluminum metal-organic framework (actAl-MOF-TCPPCu) compound with a vapor of the volatile organic sulfur compound (VOSC) diethyl sulfide (DES). First, compound was synthesized by post-synthetic modification (PSM) of Al-MOF-TCPPH compound by inserting Cu ions into the porphyrin ring and characterized by complementary qualitative and quantitative chemical, structural, and spectroscopic analysis.
