Laser Ablation Sampling With Low‐Power Plasma: A LA‐MIP‐MS Instrument for Spaceflight
Rapid Communications in Mass Spectrometry, Volume 40, Issue 3, 15 February 2026.ABSTRACT Rationale Inductively coupled plasma (ICP) is a commonly used ion source for mass spectrometry‐based chemical analysis of a wide range of materials. Traditional ICP ion sources use high power (> 1000 W) and significant gas flow (> 10 L/min), rendering them unsuitable for spaceflight, as they are too resource‐intensive for planetary spacecraft.

A general high order two-dimensional panel method
, 2017 We develop an efficient and high order panel method with applications in airfoil design. Through the use of analytic work and careful considerations near singularities our approach is quadrature-free.

Enhanced Resolution in EPR Spectroscopy Using para‐Hydrogen Matrices
Angewandte Chemie International Edition, Volume 65, Issue 6, 2 February 2026.We demonstrate the advantageous properties of solid para‐hydrogen (p‐H2) matrices for electron paramagnetic resonance (EPR) spectroscopy by investigating the 2,2,6,6‐tetramethylpiperidinyloxyl (TEMPO) radical and an in situ generated P‐centered mono‐radical.

Dispersed Nickel on Gallium Liquid Metal for Nitrate Reduction to Ammonia
Small Structures, Volume 7, Issue 2, February 2026.Developing sustainable catalytic systems for green ammonia synthesis is essential to achieving net‐zero emission targets. This study introduces a liquid Ni–Ga alloy catalyst with dispersed Ni sites for efficient nitrate‐to‐ammonia conversion with exceptional Faradaic efficiency and considerable production rate.

A SVD accelerated kernel-independent fast multipole method and its application to BEM
, 2013 The kernel-independent fast multipole method (KIFMM) proposed in [1] is of almost linear complexity. In the original KIFMM the time-consuming M2L translations are accelerated by FFT.

The Inverse Fast Multipole Method
, 2014 This article introduces a new fast direct solver for linear systems arising out of wide range of applications, integral equations, multivariate statistics, radial basis interpolation, etc., to name a few. \emph{The highlight of this new fast direct solver is that the solver scales linearly in the number of unknowns in all dimensions.} The solver ...

Images and plane waves : efficient field computation in electromagnetics and acoustics [PDF]
, 2006 In some simple or canonical problems, analytical solutions offer the most efficient way to compute the electromagnetic or acoustic fields. For arbitrary geometries, efficient numerical methods are needed.

Angewandte Chemie, Volume 138, Issue 1, 2 January 2026.Alle Seltenerdelemente bilden bekanntlich tri‐ und auch di‐valente Verbindungen. Wenige tetra‐valente Verbindungen sind auch bekannt; kürzlich wurden die ersten Moleküle und Kristalle mit Praseodym(+5) synthetisiert. Der hier definierte atomare Ionisations‐Quotient IQ legt nahe, dass Ln(+4)‐Verbindungen mit geeigneten Liganden für fast alle 4f‐Elemente

Advanced Healthcare Materials, Volume 15, Issue 4, 26 January 2026.Polymer‐based drug delivery systems can effectively overcome the limitations of free drugs in terms of solubility, stability, and plasma half‐life, yet their development has traditionally relied on time‐consuming trial‐and‐error approaches. This review highlights recent advances in applying molecular simulation to the design of polymer‐based drug ...
