The Occurrence and Morphology of Naturally Occurring Respirable Mordenite Mineral Fibres in New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Mordenite is a naturally occurring zeolite mineral that is the seventh most common zeolite mineral globally, forming at low temperatures (≥100°C) in hydrothermal systems. In New Zealand, extensive deposits of mordenite are commonly associated with areas of hydrothermal alteration, particularly in the Coromandel and Taupo Volcanic Zones.

Low-sulfidation epithermal Au mineralization in the Tikmehdash 2 deposit (southeast of Bostan Abad): Constraints on geology, mineralization, geochemistry, and fluid inclusions

Journal of Economic Geology
Tikmehdash 2 gold (Au) deposit is part of the Miyaneh-Bostan Abad metallogenic subzone. Au mineralization occurs in Mn- and Au-bearing quartz veins hosted by Eocene and Miocene volcanic-sedimentary sequences.

Boron‐10 carriers and their applications in boron neutron capture therapy

Precision Radiation Oncology, Volume 10, Issue 2, Page 205-241, June 2026.
Summary of different types of boron drugs. Abstract Boron neutron capture therapy (BNCT) has emerged as a promising therapeutic modality in cancer treatment, demonstrating the ability to selectively eliminate cancer cells through the 10B(n,α)7Li nuclear reaction with minimal side effects on normal tissues.

Martian Proton Albedo as Signature of Near‐Surface Water

Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract Understanding the Martian soil water budget is crucial not only for in situ resource utilization in future human missions to Mars, but also for reconstructing the geological and climatic history of the planet, as well as to assess the potential of ancient or even present microbial life.

Boron Neutron Capture Therapy at a Crossroads: Translational Gap and Emerging Delivery Agents

Chemistry – A European Journal, Volume 32, Issue 17, 5 May 2026.
This review surveys recent advances in boron delivery agents for BNCT, emphasizing the shift from classical small molecules to multifunctional nanocarriers and theranostic systems. By integrating targeting, imaging, and therapy, next‐generation boron compounds aim to bridge the gap between (bio)chemical innovation and clinical translation.

Network‐wide assessment of soil water content calibration and sensitivity to biomass proxies using cosmic‐ray neutron sensing in the Roaring Fork Basin, Colorado

Vadose Zone Journal, Volume 25, Issue 3, May/June 2026.
Abstract Soil water content (SWC) is a key state variable of the climate system but is often uncertain in water balance monitoring, especially in alpine environments. SWC measurements can be challenging in alpine environments due to the topography and rocky soils.
