The first visible-light-promoted dearomative fluoroalkylation of β-naphthols was realized without the assistance of any transition-metal catalysts or external photosensitizers. Inexpensive fluoroalkyl iodides were directly used as efficient fluoroalkylation reagents under very mild reaction conditions. The scope of this process was found to be general and broad, and both trifluoromethyl and perfluoroalkyl groups (-C F , -C F , and -C F ) were installed in excellent yields. Preliminary mechanistic studies suggest that visible-light-promoted intermolecular charge transfer within the naphtholate-fluoroalkyl iodide electron donor-acceptor (EDA) complex induces a single electron transfer in the absence of photocatalysts.

We review recent progress in developing effective field theories (EFTs) for non-equilibrium processes at finite temperature, including a new formulation of fluctuating hydrodynamics, and a new proof of the second law of thermodynamics. There are a number of new elements in formulating EFTs for such systems. Firstly, the nature of IR variables is very different from those of a system in equilibrium or near the vacuum. Secondly, while all static properties of an equilibrium system can in principle be extracted from the partition function, there appears no such quantity which can capture all non-equilibrium properties. Thirdly, non-equilibrium processes often involve dissipation, which is notoriously difficult to deal with using an action principle. The purpose of the review is to explain how to address these issues in a pedagogic manner, with fluctuating hydrodynamics as a main example.

The first example of UV light-induced, copper-catalyzed regio- and stereoselective decarboxylative coupling of α,β-unsaturated acids with alkyl iodides was reported. Under standard conditions, the 1°, 2°, and 3° alkyl iodides proceeded smoothly with the E-selective alkenes obtained in uniformly good yields and high stereoselectivities.

This study investigated the effect of non-task language in a language switching experiment. Non-task language refers to participants' languages (regardless of proficiency level) that are not used in any trials throughout the experiment. We recruited 60 Tibetan-Chinese-English trilinguals (12th-grade high school students with a median age of 17) to perform a lexical decision (word vs. non-word) task in only two of their languages. We repeated the experiment three times to present each language pair once. In each experiment, the participants were divided into two groups that significantly contrasted with each other in their non-task language while remaining comparable in the two task languages. Response time (RT) and error rate (ER) have been examined to evaluate task performance. The interaction between task performance and the participants' proficiency in the non-task language was also examined. The results showed anull effect of language switching. In addition, the effect of the non-task language was not found. These results were interpreted with reference to the main models of bilingual visual word recognition and the role of orthography specificity.

The temperature dependence of the coercivity, Hc(T), at low temperatures in Dy(Fe0.9 4M0.1)2(M=Ga, Al), SmCo3.5Cu1.5, and Sm(CoCuFeTi)6.8 is interpreted in terms of a physical model in the framework of the quantum regime. It is believed that the motion of the narrow domain wall in the compounds is a quantum excitation and activation process, and it is also shown that the anomalies of Hc(T) at low temperatures in the hard magnets are due to the competition results of the quantum mechanical motion and the intrinsic scattering of their domain walls. Finally, the theoretical results are observed to be satisfactorily consistent with the experiments.
