Effects of Silica, Fe(II), and Mn(II) on Electrochemical Lithium Intercalation: Implication for Lithium Extraction from Geothermal Brines

September 11, 2025
Author(s)
Yongchang Yu, Christopher Stafford, Lingchen Kong, Keven Mckenzie Jr, Michael Wagner, Xitong Liu
Electrochemical lithium intercalation is a promising direct lithium extraction technology owing to its high lithium selectivity and elimination of chemical usage, making it an environmentally friendly solution for lithium extraction from geothermal brine

Intrinsic Direct Air Capture

September 10, 2025
Author(s)
Austin McDannald, Daniel Siderius, Brian DeCost, Kamal Choudhary, Diana Ortiz-Montalvo
How can you tell if a sorbent material will be good for any gas separation process – without having to do detailed simulations of the full process? We present new metrics to evaluate solid sorbent materials for Direct Air Capture (DAC), a particularly

Symmetry-breaking induced surface magnetization in non-magnetic RuO2

September 8, 2025
Author(s)
Quoc Dai Ho, Quang To, Ruiqi Hu, Garnett Bryant, Anderson Janotti
Altermagnetism is a newly identified phase of magnetism distinct from ferromagnetism and antiferromagnetism. RuO2 has been considered a prototypical metallic altermagnet with a critical temperature higher than room temperature. Previous interpretations of

Quantum Vibro-Polaritonic Sensing

August 15, 2025
Author(s)
Peng Zheng, Stephen Semancik, Ishan Barman
Vibrational spectroscopies are pivotal in analytical methods and biomedical diagnostics owing to their singular ability to provide molecular specificity. Yet, they are intrinsically limited by weak light-matter interactions and their vulnerability to

Interfacial Alloying Contributions to the Magnetic Proximity Effect in Pt/Dysprosium Iron Garnet

August 12, 2025

Miela J. Gross, Javier Herrero-Martin, Sergio Valencia, Alexander Grutter, Julie Borchers, Yongseong Choi, Gilberto Fabbris, Allison Kaczmarek, Alexander E. Kossak, Jackson Bauer, Subhajit Kundu, Supriya Ghosh, K. A. Mkhoyan, Angela Wittmann, Caroline A. Ross
The magnetic proximity effect (MPE) plays an important role in the behavior of heavy-metal (HM)/ferro- or ferrimagnet thin film heterostructures, but for HM/rare earth iron garnet interfaces the presence and magnitude of the MPE has been debated. We

The JARVIS Infrastructure is All You Need for Materials Design

July 23, 2025
Author(s)
Kamal Choudhary
The Joint Automated Repository for Various Integrated Simulations (JARVIS) is a unified platform for multiscale, multimodal, forward, and inverse materials design. It integrates diverse theoretical and experimental approaches, including density functional

Reference Correlation of the Viscosity of Argon

July 10, 2025
Author(s)
Sofia Sotiriadou, Konstantinos Antoniadis, Marc Assael, Marcia Huber
This paper presents a new wide-ranging reference correlation for the viscosity of argon, incorporating recent ab initio dilute gas calculations and critically evaluated experimental data. The correlation is designed to be used with a high-accuracy

Human Use Conditions in Fatigue of Intravenous Leads Used in Cardiac Implanted Electronic Devices

July 3, 2025

Timothy Quinn, Charles Swerdlow, Lucas Koepke, James Dawson, Nicki Mara, Jason Santelli, Diane Muff, Jordan Savela, Alex Felber, Michael Friedrich, Jens Rump, Torsten Luther, Jake Benzing, Michael Peterson, Mohit Chawla, Stanislav Weiner, Byron Colley III, Jonathan Piccini
Background: Transvenous lead conductors are subject to fatigue fracture from repetitive bending stresses, which are proportional to alternating curvature. Knowledge of the stresses on implanted leads (fatigue environment) is a prerequisite for developing a

Advanced Characterization of the Cure Kinetics of a Liquid Encapsulant

June 26, 2025
Author(s)
Anthony Kotula, Ran Tao, Jianwei Tu, Young Lee, Gale Holmes
Liquid encapsulants are versatile packaging materials that provide electrical insulation and mechanical protection for microelectronic devices. As more advanced encapsulants are formulated to address modern packaging needs, advanced characterization

X-ray scintillating lanthanide-based coordination polymers

Elizabeth Decoteau, Claire Belatti, Huong Giang Nguyen, Luiz Jacobsohn, Robert Surbella, III, Christopher Cahill
Reported are the syntheses and characterization of 25 lanthanide-containing coordination polymers exhibiting four structure types: type I': [Ln(TFTP)1.5(bpy)] (Ln = La3+-Nd3+), type I: [Ln(TFTP)1.5(bpy)(H2O)] (Ln = Sm3+-Lu3+), type II': [Pr(TFTP)1.5(phen)]

Surface Wrinkling of Plasma-Exposed PDMS is Caused by Water Vapor Sorption: An Optical Environmental Sensor

June 18, 2025
Author(s)
Jack Douglas, Zain Ahmad, Tyagi Tyagi, Shuning Xiang, Jerry Heng, Pedro Patricio, Paulo Teixeira, Christopher Stafford, Joao T. Cabral
Wrinkling of polydimethylsiloxane (PDMS) has unlocked a plethora of technological applications, from tunable surface wetting to photonic response. Surface undulations with prescribed wavelength and amplitude are excited by in-plane mechanical compression

Residual stress-assisted static globularization in electron beam powder bed fusion Ti-6Al-4V from powder recovery and hot isostatic pressing

June 10, 2025
Author(s)
Nicholas Derimow, Thomas Berfield, Keenan Hanson, Jake Benzing, Nikolas Hrabe
The residual stresses from controlled powder recovery blasting on electron beam powder bed fusion (PBF-EB) Ti-6Al-4V were investigated via hole drilling, profilometry, and microscopy. After hot isostatic pressing, the near-surface lamellar the near-surface

Spin-lattice entanglement in CoPS3

June 10, 2025
Author(s)
Angela Hight Walker, Kevin Garrity, Rebecca Dally
Complex chalcogenides in the MPS3 family of materials (M = Mn, Fe, Co, and Ni) display remarkably different phase progressions depending upon the metal center orbital filling, character of the P–P linkage, and size of the van der Waals gap. There is also a

Examining Generalizability of AI Models for Catalysis

June 7, 2025
Author(s)
Kamal Choudhary, Shih Han Wang, Hongliang Xin, Luke Achenie
In this work, we investigate the generalizability of problem-specific machine-learning models for catalysis across different datasets and adsorbates, and examine the potential of unified models as pre-screening tools for density functional theory
