Rare Metals, EarlyView.ABSTRACT Cost‐effective and efficient non‐noble‐metal catalysts for selective lignin hydrogenolysis remain elusive, representing a significant challenge in biorefinery. Here, we prepared a nitrogen‐doped carbon supported CoNi bimetallic catalyst, which was successfully derived from zeolitic imidazolate framework (ZIF) via high‐temperature pyrolysis ...

Æ E Æ Å – Reshaping the Role of Træna Fishermen
, 2022 This diploma project aims to strengthen the viability of Træna’s community by proposing an ocean research facility in the archipelago, enabling the next generation of local fishermen to collect oceanographic data while working at sea. The idea of the fisherman as oceanographer is inextricably linked to the architectural program on the island of ...

, 2012 以水稻、高粱和玉米为研究对象,考察了微囊藻毒素对受试作物的毒性差异,研究了不同浓度MC对萌发及萌发初期生长发育的影响,不同灌溉时期对受试作物生长发育的影响,检测指标包括发芽率、株高、鲜重、叶绿素、根系活力等。结果表明,受试作物对微囊藻毒素毒性并不一致,水稻发芽率受到明显抑制,高粱发芽率基本不受影响,玉米出现了低浓度促进、高浓度抑制的现象;MC对水滔、高粱和玉米的光合作用、株高和鲜重没有抑制作用,反而有一定的促进效果;不同灌溉时间条件下的研究结果表明,萌发前对高粱和玉米染毒会明显抑制植株根系活力 ...

Rare Metals, EarlyView.ABSTRACT As a promising alternative to sluggish Li2CO3‐based Li‐CO2 electrochemistry, Li2C2O4 offers a favorable 2e− discharge pathway, yet its selective formation and reversible decomposition remain debated. Herein, we propose a nonmetal‐metal synergistic catalyst—B‐Ti coregulated layered transition metal boride Ti18B18O9/graphene (B‐Ti/TiBOG)—to ...

Mechanism of mixture suppression in newt olfactory receptor neurons [PDF]
, 2001 ヒトを含め脊椎動物は多くの種類の匂いを識別することができ，その数は数万種類とも言われている。環境中では，匂いは通常複数の匂い物質による混合臭として存在しており，嗅覚系においてそれらの識別が行われる。嗅細胞における興奮性の匂い応答については研究が進んでおり，次の様なシグナル伝達経路を示す。匂い分子はレセプタータンパク質によって受容され，Gタンパク質を経てアデニル酸シクラーゼ（adenylate cyclase）が活性化され，ATPからcAMPを合成する。その結果細胞内cAMP濃度が上昇し ...

Rare Metals, EarlyView.ABSTRACT Harnessing solar energy for self‐heating presents an effective strategy to suppress surface ice formation. In this paper, we fabricated nano‐silver‐modified multilayer graphene sheets (Ag@MGs) that integrate photothermal and superhydrophobic properties for anti‐icing applications.
