THE RAMAN SPECTRUM OF GYPSUM [PDF]

Proceedings of the National Academy of Sciences, 1929
In an investigation of the Raman spectra of some ionized substances in aqueous solution, it was found [1] that the frequency shift given by a solution of potassium carbonate was in fairly close agreement with the strongest shift given by calcite. Data for such a comparison in other cases do not appear to exist, for change of frequency on scattering has

Multifactorial Screening for Fine‐Scale Selection of CCS Industrial Clusters and Hubs in Brazil

Greenhouse Gases: Science and Technology, EarlyView.
ABSTRACT As Brazil moves toward implementing its decarbonization commitments, carbon capture and storage (CCS) hubs are emerging as a key pathway for large‐scale CO2 abatement in hard‐to‐abate sectors. This paper presents a multifactorial, data‐driven framework to screen and prioritize potential CCS industrial clusters and hubs across Brazilian regions,

A Reproducible SEM Surface Imaging Protocol for Monitoring Microstructural Changes During Gas–Rock Interactions

Greenhouse Gases: Science and Technology, EarlyView.
ABSTRACT Reliable characterization of mineralogical and textural changes in rock samples is essential for understanding fluid–rock interactions, particularly in experimental studies simulating subsurface conditions. This study presents a reproducible protocol for scanning electron microscopy (SEM) analysis of rock surfaces before and after exposure to ...

Optimizing feather hydrolysate via machine learning for microbial recycling of waste concrete fines

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND The concrete industry faces significant challenges from CO2 emissions and the disposal of waste concrete fines (WCF). Microbially induced calcite precipitation (MICP) can bind WCF into bioconcrete, but the high cost of commercial culture media hinders its application.

Evaluating the Effectiveness of 3D‐Printed Models in Tooth Morphology Training for Students

Journal of Dental Education, EarlyView.
ABSTRACT Purpose/Objectives Tooth morphology is a fundamental aspect of dental education, essential for various clinical disciplines. Traditional teaching methods, such as 2D visualizations, gypsum models, and wax or soap carving, have been widely used to develop students’ spatial understanding and manual skills.

A Novel Approach of Semi‐Quantifying Gypsum in Sedimentary Rocks by Visible and Near‐Infrared Diffuse Reflectance Spectroscopy

Geochemistry, Geophysics, Geosystems
Gypsum is one of the major evaporite minerals that can be used as a sensitive archive for past climate change, revealing variations in the hydrological cycle and dry‐wet climatic alternations. Measuring variations in gypsum content, rapidly and with high

Immersive Technologies in Dental Education: Global Adoption Patterns From a 2025 Survey

Journal of Dental Education, EarlyView.
ABSTRACT Purpose/Objectives Dental education is undergoing a digital transformation, yet the adoption of immersive technologies such as haptic virtual reality (HVR) remains limited. This study aimed to map global adoption trends, barriers, and opportunities for equitable integration of HVR in dental curricula.
