First 20 Years of Orbitrap Mass Spectrometry as the Mainstream Analytical Technique
Mass Spectrometry Reviews, EarlyView.ABSTRACT This review traces the first 20 years of Orbitrap mass spectrometry as a mainstream high‑resolution and accurate‑mass (HR/AM) technology. It outlines the historical development of the Orbitrap analyzer, the evolution of major instrument families, and the key technological innovations that enabled its widespread adoption. Particular emphasis is

Systematic survey of pulsed laser deposition of YBa2Cu3O7 superconductor films on metal tapes
Scientific ReportsPulsed laser deposition (PLD) of biaxially oriented cuprate superconducting films rapidly progresses from versatile research method to large scale production method. This development is likely the first example when PLD gets to industrial production tool.

Polymer International, EarlyView.A new semicrystalline copolymer, PTBT‐3OBu, was synthesized. Intramolecular S···O conformational locks induce high backbone planarity, promoting strong interchain coupling and molecular ordering in thin films, seen in an optical red shift. This synergy between planarity and semicrystalline morphology is promising for photovoltaic and electrochromic ...

Ultrathin Freestanding BiFeO3 Membranes Grown by Pulsed Laser Deposition
Small, EarlyView.Ultrathin freestanding BiFeO3 membranes down to five‐unit cells are realized by pulsed laser deposition using a water‐soluble Sr3Al2O6 sacrificial layer. Strontium diffusion is revealed to drive the spontaneous formation of an Aurivillius‐like phase, while ultrathin SrRuO3 interlayers suppress interfacial intermixing, preserve polar tetragonality, and ...

Molecular‐Scale Geometric Control of Organosiloxane Cage Frameworks Via Rigid Organic Bridges
Small Methods, EarlyView.Rigid phenylene bridges with predefined Si–Ph–Si angles enable molecular‐level control of cage‐type organosiloxane frameworks. Hydrolysis and condensation of meta‐ and para‐bis(triethoxysilyl)benzene in the presence of tetramethylammonium hydroxide yield a mixture of cage trimers and tetramers, and hexamers, respectively, providing a new insight into ...

Appraisal of Six Natural Mica Reference Materials for In Situ Rb‐Sr Geochronology
Geostandards and Geoanalytical Research, EarlyView.Key Points Evaluated six natural mica reference materials for in situ LA‐ICP‐MS/MS Rb‐Sr geochronology using geochemical, microstructural and isotopic characterisation. Identified robust primary reference materials: Mount Dromedary biotite (99.37 Ma) and Mica‐Fe biotite (307.75 Ma). La Posta biotite and Högsbo muscovite are suitable secondary reference
