Unveiling SEI Formation Dynamics of PEO: LiTFSI with Lithium Metal: An In Situ Approach Combining SIMS, XPS, and CTTA
Electrolyte interfaces with freshly plated lithium metal are crucial for the development of reservoir‐free all‐solid‐state batteries (ASSBs). This study provides an in‐depth characterization of the polyethylene oxide (PEO) lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) interphase with lithium metal resembling reservoir‐free cell conditions. Using an in situ setup in both secondary ion mass spectrometry (SIMS) and X‐ray photoelectron spectroscopy (XPS), the dynamic evolution of the solid electrolyte interphase (SEI) layer is investigated at 60 °C. Lithium metal plating is conducted with an electron flood gun, ensuring controlled lithium deposition and enabling direct identification of intermediate reaction products. Time‐of‐flight‐ (ToF‐) and Orbitrap‐SIMS are employed to provide high‐resolution insights into the formation of inorganic and organic SEI components coming from PEO and LiTFSI degradation after plating. XPS further reveals chemical transformations occurring at the interface. Additionally, coulometric titration time analysis (CTTA) captures the kinetic aspect of PEO: LiTFSI reaction with lithium metal, highlighting the influence of molecular weight and salt concentration on initial reaction speed and long‐term stability. By integrating high‐resolution SIMS analysis with surface‐sensitive XPS and electrochemical methods, a comprehensive approach is offered to better understand the dynamic behavior of the polymer electrolyte | lithium metal interphase under conditions relevant to reservoir‐free battery concepts. This study examines the interphase formation of polyethylene oxide (PEO) and lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) with lithium metal. Utilizing secondary ion mass spectrometry (SIMS), X‐ray photoelectron spectroscopy (XPS), and coulometric titration time analysis (CTTA), it analyzes the solid electrolyte interphase (SEI) layer's evolution, reaction kinetics, and stability, offering insights into chemical transformations under realistic battery conditions.

Secondary Ion Mass Spectral Imaging of Metals and Alloys
Secondary Ion Mass Spectrometry (SIMS) is an outstanding technique for Mass Spectral Imaging (MSI) due to its notable advantages, including high sensitivity, selectivity, and high dynamic range. As a result, SIMS has been employed across many domains of science. In this review, we provide an in-depth overview of the fundamental principles underlying SIMS, followed by an account of the recent development of SIMS instruments. The review encompasses various applications of specific SIMS instruments, notably static SIMS with time-of-flight SIMS (ToF-SIMS) as a widely used platform and dynamic SIMS with Nano SIMS and large geometry SIMS as successful instruments. We particularly focus on SIMS utility in microanalysis and imaging of metals and alloys as materials of interest. Additionally, we discuss the challenges in big SIMS data analysis and give examples of machine leaning (ML) and Artificial Intelligence (AI) for effective MSI data analysis. Finally, we recommend the outlook of SIMS development. It is anticipated that in situ and operando SIMS has the potential to significantly enhance the investigation of metals and alloys by enabling real-time examinations of material surfaces and interfaces during dynamic transformations.

Team of vipers : my 500 extraordinary days in the Trump White House
After standing at Donald Trump's side on Election Night, Cliff Sims joined him in the West Wing as Special Assistant to the President and Director of White House Message Strategy. He soon found himself pulled into the President's inner circle as a confidante, an errand boy, an advisor, a punching bag, and a friend. Sometimes all in the same conversation. As a result, Sims gained unprecedented access to the President, sitting in on private meetings with key Congressional officials, world leaders, and top White House advisors. He saw how Trump handled the challenges of the office and how he saw the world. For five hundred days, Sims also witnessed first-hand the infighting and leaking, the anger, joy, and recriminations. He had a role in some of the President's biggest successes, and he shared the blame for some of his administration's worst disasters. He gained key insights into the players of the Trump West Wing, from Jared Kushner and John Kelly to Steve Bannon and Kellyanne Conway. Sims even helped Trump craft his enemies list, knowing who was loyal and who was not. And he took notes. Hundreds of pages of notes. In real-time. Sims stood with the President in the eye of the storm raging around him, and now he tells the story. The story of power and palace intrigue, backstabbing and bold victories, as well as painful moral compromises.

Smart Ligands for Efficient 3d-, 4d- and 5d-Metal Single-Molecule Magnets and Single-Ion Magnets
There has been a renaissance in the interdisciplinary field of Molecular Magnetism since ~2000, due to the discovery of the impressive properties and potential applications of d- and f-metal Single-Molecule Magnets (SMMs) and Single-Ion Magnets (SIMs) or Monometallic Single-Molecule Magnets. One of the consequences of this discovery has been an explosive growth in synthetic molecular inorganic and organometallic chemistry. In SMM and SIM chemistry, inorganic and organic ligands play a decisive role, sometimes equally important to that of the magnetic metal ion(s). In SMM chemistry, bridging ligands that propagate strong ferromagnetic exchange interactions between the metal ions resulting in large spin ground states, well isolated from excited states, are preferable; however, antiferromagnetic coupling can also lead to SMM behavior. In SIM chemistry, ligands that create a strong axial crystal field are highly desirable for metal ions with oblate electron density, e.g., TbIII and DyIII, whereas equatorial crystal fields lead to SMM behavior in complexes based on metal ions with prolate electron density, e.g., ErIII. In this review, we have attempted to highlight the use of few, efficient ligands in the chemistry of transition-metal SMMs and SIMs, through selected examples. The content of the review is purely chemical and it is assumed that the reader has a good knowledge of synthetic, structural and physical inorganic chemistry, as well as of the properties of SIMs and SMMs and the techniques of their study. The ligands that will be discussed are the azide ion, the cyanido group, the tris(trimethylsilyl)methanide, the cyclopentanienido group, soft (based on the Hard-Soft Acid-Base model) ligands, metallacrowns combined with click chemistry, deprotonated aliphatic diols, and the family of 2-pyridyl ketoximes, including some of its elaborate derivatives. The rationale behind the selection of the ligands will be emphasized.

Quality and postharvest conservation of sour passion fruit genotypes
The postharvest phase is a limiting factor for climacteric fruits such as passion fruit due to rapid deterioration causing wilting and favoring the occurrence of pathogenic microorganisms. From this perspective, this study aimed to evaluate the postharvest quality of passion fruit genotypes cultivated in Mâncio Lima, Acre, as a function of the storage period after harvest. The experiment was set up and conducted at the Plant Science Laboratory of the Federal University of Acre, Campus Floresta. The experimental design was in randomized blocks, in a 10 x 5 factorial arrangement referring to 10 sour passion fruit genotypes and five postharvest evaluation periods, with three replications of six fruits. The fruits were evaluated for physical and chemical quality. Analysis of variance and polynomial regression were performed at 5% significance. The genotypes showed oscillations regarding the physical and chemical characteristics of the fruits depending on the storage time. All evaluated genotypes are recommended for cultivation. However, when harvested directly from the ground after detached from the plant, fruits must be stored for up to 10 days at room temperature.
