Identifying Recycled Materials Using Mo Isotopes in Intraplate Alkali Basalts From the Southeastern Margin of Tibetan Plateau

open access: yesGeochemistry, Geophysics, Geosystems
Mantle heterogeneity in lithology and geochemistry is often attributed to recycled subducted materials. While distinct mantle end‐members are identified by radiogenic isotopes, the specific recycled materials contributing to this heterogeneity remain ...

Plants back: Re‐envisioning botanical garden collections management for indigenous crops

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Botanical gardens and other ex situ collections play a key role in preventing plant extinctions, yet the needs of Indigenous crop cultivars are not being met by conventional botanical collections management practices. Inspired by Indigenous land care restoration movements centering plant–human–society relationships, we propose a path toward reciprocal ...

Biomimetic robots driven by smart materials: Motion forms, stimulation methods and applications

open access: yesResponsive Materials, EarlyView.
Biomimetic robots enhance adaptability by mimicking biological systems, but rigid materials limit performance. Smart materials with stimuli responsiveness and shape adaptability enable more flexible actuation and improved environmental interaction.

Cold‐curing effects on the strength development and sulfuric acid resistance of basalt fiber‐reinforced hybrid alkali‐activated slag mortars

open access: yesStructural Concrete, EarlyView.
Abstract Cold weather conditions impose substantial constraints upon the performance and long‐term resilience of concrete materials. Alkali‐activated slag (AAS) presents itself as a promising substitute, exhibiting sustained hydraulic activity even when exposed to ambient conditions characterized by low temperatures.

Evaluation of cold joint effects on the microstructure and mechanical behavior of three‐dimensional printed concrete specimen

open access: yesStructural Concrete, EarlyView.
Abstract 3D concrete printing (3DCP) is an automated construction technique that uses an extrusion process to fabricate structures efficiently. However, the layer‐by‐layer process can create interlayer weaknesses, and interruptions during printing can result in cold joints, which can negatively affect the structural behavior.

Structural testing and analytical model of Reinforced Concrete (RC) prisms with 3D‐printed concrete permanent formwork under compressive loading

open access: yesStructural Concrete, EarlyView.
Abstract The implementation of traditional steel reinforcement in 3D concrete printed structures is a major challenge. Although 3D‐printed structures may be used as formwork, the knowledge about their structural contribution is limited. This research aims to experimentally evaluate the structural performance of reinforced concrete prisms with 3D ...

The Pelona-Pico Duarte basalts Formation, Central Hispaniola: an on-land section of Late Cretaceous volcanism related to the Caribbean large igneous province

open access: yesGeologica Acta, 2011
Located in Central Hispaniola, the Pelona-Pico Duarte basalts Formation (Fm.) offers an opportunity to study the Late Cretaceous Caribbean large igneous province magmatism on land. It is composed by a ~2.5km-thick pile of massive and monotonous submarine
