Photosynthesis of NH3 from NO3− Using CH4 in Homogenous Rhenium Catalysis
Angewandte Chemie, EarlyView.We present a Re catalysis of one‐pot synthesis of NH3 from NO3− using CH4 as a reductant under UV light irradiation. We are able to directly convert NO3−, leading to several environmental issues, to NH3, an essential compound as a fertilizer and industrial raw material, by means of CH4, which has a high affinity with renewable resource/energy, as a ...

Advanced Intelligent Systems, EarlyView.To argue the applicability of continuum wall‐climbing robots in the nuclear industry, an electromagnetic adhering and self‐inductive sensing integrated claw is developed. The flexible claw realizes an integrated design of the physical structure and excitation circuit. An automatic contact strategy based on fuzzy controller is established, which enables

A new formulation of the law of octic reciprocity for primes ≡±3(mod8) and its consequences
International Journal of Mathematics and Mathematical Sciences, 1982 Let p and q be odd primes with q≡±3(mod8), p≡1(mod8)=a2+b2=c2+d2 and with the signs of a and c chosen so that a≡c≡1(mod4). In this paper we show step-by-step how to easily obtain for large q necessary and sufficient criteria to have (−1(q−1)/2q(p−1)/8≡(a−

Harbingers of Artin's Reciprocity Law. I. The Continuing Story of Auxiliary Primes [PDF]
arXiv, 2011 In this article we present the history of auxiliary primes used in proofs of reciprocity laws from the quadratic to Artin's reciprocity law. We also show that the gap in Legendre's proof can be closed with a simple application of Gauss's genus theory.

Norm groups and class fields of formally real quasilocal fields
, 2008 This paper establishes a relationship between finite extensions and norm groups of formally real quasilocal fields, which yields a generally nonabelian local class field theory, including analogues to the fundamental correspondence, the local reciprocity

Advanced Intelligent Systems, EarlyView.Inspired by the eye movements of humans, a multi‐degree‐of‐freedom (multi‐DOF) miniature piezoelectric actuator with a square‐circular ring structure is proposed. The actuator demonstrates a well‐balanced performance in miniaturization, operational efficiency, actuation precision, and load‐driving capability.
