Targeting Peptostreptococcus anaerobius with an Iron‐Based Nanozyme Reverses Ferroptosis Resistance and Enhances Antitumor Immunity in Colorectal Cancer

Advanced Science, EarlyView.
An iron‐based nanozyme selectively eliminates intratumoral P. anaerobius while catalytically generating ROS to induce ferroptosis, synergistically suppressing colorectal cancer growth and activating anti‐tumor immunity through immunogenic cell death. ABSTRACT The intratumoral microbiota is a critical determinant of therapeutic outcomes in colorectal ...

Analysis of microtraces in invasive traumas using SEM/EDS

Forensic Science International, 2012
Scanning electron microscopy in combination with energy-dispersive X-ray spectrometry (SEM/EDS) is a proven forensic tool and has been used to analyze several kinds of trace evidence. A forensic application of SEM/EDS is the examination of morphological characteristics of tool marks that tools and instruments leave on bone.

Fly ash characterization by SEM–EDS

Fuel, 2006
A study conducted at the National Energy Technology Laboratory characterized twelve Class F fly ash samples from nine PC power plants in PA, WV, MD and TN, using scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). Both the surface and internal structure of fly ash particles were analyzed.

Innovative unattended SEM-EDS analysis for asbestos fiber quantification

Talanta, 2018
Scanning electron microscopy with energy dispersive spectrometry (SEM-EDS) is the only affordable analytical technique that can discriminate both morphology and elemental composition of inorganic fibers. SEM-EDS is indeed required to quantify asbestos in confounding natural matrixes (e.g. ophiolites), but is also time-consuming, operator dependent, and

SEM–EDS analysis and discrimination of forensic soil

Forensic Science International, 2004
Soils vary among different areas, and have some characteristics because of the natural effects and transfers made by human and other living beings in time. So that forensic examination of soil is not only concerned with the analysis of naturally occurring rocks, minerals, vegetation, and animal matter.

Fatigue fracture analysis of amalgam by SEM-EDS

Dental Materials, 1986
Abstract The purpose of this study was to examine cracks generated in dental amalgam during compressive fatigue. Cracks were observed using SEM and composition was evaluated by Energy Dispersive X-ray Spectroscopy (EDS). Amalgam cylinders showed classical fatigue fracture.

Characterization of Pyrotechnic Reaction Residue Particles by SEM/EDS

Journal of Forensic Sciences, 2003
Abstract Today the method commonly used for detecting gunshot residue is through the combined use of scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). In recent years, this same methodology began to find use in detecting and characterizing pyrotechnic reaction residue (PRR) particles whether produced by ...

SEM/EDS comparison of polar and seasonal temperate ice

Microscopy Research and Technique, 2003
AbstractWe have developed a method employing a scanning electron microscope (SEM) and energy dispersive X‐ray spectroscopy for examining uncoated ice specimens. By permitting the ice to sublimate in the SEM at temperatures between −115° and −60°C, enough ions are produced to prevent specimen charging.
