People and Nature, EarlyView.Abstract Currently, scholarship on education to foster connectedness with nature primarily focuses on children. As adults likewise face the disconnection from nature and play a key role in influencing children, it is important to understand how they perceive, engage in, and benefit from relevant programmes.

PLANTS, PEOPLE, PLANET, EarlyView.The jewel‐like flowers of Thismia are as rare as they are beautiful, often recorded from only a single site per species. Access to 15 populations of T. kobensis has enabled an uncommon, range‐wide assessment of morphology, genetics, and fungal partners. Our analyses showed that T.

Rare Metals, EarlyView.ABSTRACT The poor Zn chemistry of Zn metal anode and sluggish reaction kinetics of cathodes at high mass loadings are two crucial issues for hindering the application of aqueous Zn‐ion batteries (AZIBs). Herein, the hierarchical porous N‐doped carbon fibers (HPNCFs) were proposed to simultaneously optimize the reversibility of Zn plating/stripping of ...

Rare Metals, EarlyView.ABSTRACT Porous NiTi alloys are widely used in biomedical and engineering fields. Using the PBF‐LB technique, the TPMS and Voronoi porous parts with a porosity of ∼67% and a minimum feature size of 0.15 ± 0.02 mm were fabricated. Although the bulk sample fabricated with the same parameters is defect‐free, μ‐CT reconstruction on the porous sample ...

シラネアオイ Glaucidium Palmatum Sieb. et. Zucc. ノ ヨウヘン バイヨウ [PDF]
, 2000 【緒言】シラネアオイ(Glaucidium palmatum)は，北海道から本州中部にかけて広がる温帯林や亜寒帯林のやや湿った林床に自生する多年生植物である.春には1茎当たり1輪の大きな4枚のがく片が花弁状をなす青紫色の美しい花を咲かせ，登山者や自然愛好家に人気の高い植物である.佐野らによれば，シラネアオイは以前分類されていたキンポウゲ科から独立し，1科1属1種の貴重な日本特産種である.近年の土地開発により杉等の人工林が増加する一方，雑木林を含む落葉広葉樹林の減少に伴って，この植物は数を激減させ ...

Rare Metals, EarlyView.ABSTRACT Photocatalytic molecular oxygen (O2) activation provides a sustainable approach to produce singlet oxygen (1O2) for organic contaminants detoxification. However, the charge carriers‐involved pathway usually suffers from unsatisfactory 1O2 production efficiency owing to energy loss caused by photogenerated hole‐mediated superoxide species (•O2−

Rare Metals, EarlyView.ABSTRACT Rare earth elements (REEs) play an irreplaceable role in modern technology and industry. However, due to the highly similar physicochemical properties among REEs, their separation remains a significant challenge. Additionally, REEs often exist in low‐concentration solutions, making efficient REE recovery an urgent task.
