Archaeometry, EarlyView.ABSTRACT The materiality of the white pigment motif at the Cloggs Cave rockshelter, near Buchan in GunaiKurnai Country (southeastern Australia), contains details about the cultural and environmental contexts in which the art was created and preserved. Here, we (1) present physicochemical analyses of the pigment composition; (2) explore implications for

Sedimentology, EarlyView.ABSTRACT Classical models of formation of sedimentary siliceous rocks (flint, chert, opoka) commonly assume that the Cretaceous marine silicon (Si) cycle was primarily biologically controlled, broadly analogous to the modern ocean. In this framework, siliceous sponges are regarded as the principal source of dissolved silica (dSi) to sediment porewaters,

Water and Environment Journal, EarlyView.This review examines the physicochemical properties of geopolymers, focusing on the effects of calcium content, heavy metal impurities and acid activation. It distinguishes geopolymers from other alkali‐activated materials based on structure and synthesis precursors. Their use as water treatment adsorbents is compared with ceramic filters, highlighting

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 6, November 2026.Fabrication process of phase change microcapsules using a Pickering emulsion template method and their subsequent applications. The increasing demand for efficient thermal energy storage systems has driven the development of phase change material microcapsules (PCMMs), which provide high energy‐storage density, reversible phase change, and reduced ...

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.Abstract Ground deformation of dormant volcanoes provides critical insights into subsurface processes and potential hazards. Here we present Sentinel‐1 Interferometric Synthetic Aperture Radar (InSAR) time series (2015–2020) for Changbaishan volcano, the largest intraplate volcanic system in East Asia. We detect persistent subsidence of up to 3.5 mm/yr

Limnology and Oceanography, Volume 71, Issue 10, October 2026.Abstract Surface water–groundwater (SW–GW) exchange in tidal creeks is governed by a complex interplay of marine, terrestrial, and anthropogenic forcings. Despite this, the spectral signature of tidal controls on SW–GW fluxes and flow directions remains poorly understood, largely due to the lack of methods that resolve both infiltration and ...

Repeated Pleistocene Permafrost Episodes in the Western Pannonian Basin
Permafrost and Periglacial Processes, Volume 37, Issue 4, Page 623-644, October/December 2026.ABSTRACT Concerning the study of past periglacial processes, the Pannonian Basin is a key area as it contains the southernmost frost polygons found in Central Europe. The presence or absence of permafrost is still, however, a matter of debate, and data on the timing of frost action are also scarce.

Modelling flow and filtration in liquid composite moulding of nanoparticle loaded thermosets [PDF]
, 2012 This paper presents analytical and numerical models of liquid moulding of hybrid composites. An 1-D analytical solution of Darcy's problem, accompanied by nanoparticle filtration kinetics and conservation, has been developed.
