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.

Rare Metals, EarlyView.ABSTRACT The evolution of the γ′−Ni3(Al, Ti) phase in superalloys is governed by a coupled coalescence‐ripening mechanism driven by elemental diffusion. In this study, thermal exposure experiments were performed at 750°C and 800°C for durations ranging from 100 to 20,000 h.

Gaoya dianqi, 1991 （问）不同环境温度下液压机构的压力如何换算? （答）换算方法有3种: 方法Ⅰ:氮气预充压力PO和额定工作压力（额定油压）PH,是在环境温度为20℃下的表压值。而测压时环境温度t可能高于或低于20℃;乃外在测定位置不变时,压力随温度的变化是处于定容变化过程,即P/T=常数。P与T应采用绝对值,但作为工程应用,可以按下式进行换算。由于产品中使用kg/cm2,故未作换算。

Rare Metals, EarlyView.ABSTRACT Single‐atom catalysis hinges on fundamental challenges in precisely controlling metal‐support interactions and rationally regulating metal–adsorbate relationships. Herein, we report a universal strategy for constructing highly efficient and well‐defined Cu(I) single‐atom catalysts based on a trifurcate AlL3 molecular support.

Rare Metals, EarlyView.ABSTRACT The development of efficient and stable bifunctional catalysts remains a key challenge for green hydrogen production via electrochemical water splitting. In this study, a bimetallic Mo/Fe‐doped CoP2 nanoleaf array anchored on carbon cloth (Mo, Fe‐CoP2@CC) was synthesized from zeolitic imidazolate framework‐L (ZIF‐L) via an ion‐exchange and low‐
