Despite great interests in electrochemical energy storage systems for numerous applications, considerable challenges remain to be overcome. Among the various approaches to improving the stability, safety, performance, and cost of these systems, molecular functionalization has recently been proved an attractive method that allows the tuning of material surface reactivity while retaining the properties of the bulk material. For this purpose, the reduction of aryldiazonium salt, which is a versatile method, is considered suitable; it forms robust covalent bonds with the material surface, however, with the formation of multilayer structures and sp3 defects （for carbon substrate） that can be detrimental to the electronic conductivity. Alternatively, non-covalent molecular functionalization based on π-π interactions using aromatic ring units has been proposed. In this review, the various advances in molecular functionalization concerning the current limitations in lithium-ion batteries and electrochemical capacitors are discussed. According to the targeted applications and required properties, both covalent and non-covalent functionalizafion methods have proved to be very efficient and versatile. Fundamental aspects to achieve a better understanding of the funcfionalization reactions as well as molecular layer properties and their effects on the electrochemical performance are also discussed. Finally, perspectives are proposed for future implementation of molecular functionalization in the field of electrochemical storage.

Effect of wind stress forcing on ocean dynamics at air-sea interface

引用

Frontiers of Information Technology & Electronic Engineering 2018年第8期19卷 1056-1062页

We evidence and study the differences in turbulence statistics in ocean dynamics carried by wind forcing at the air-sea interface. Surface currents at the air-sea interaction are of crucial importance because they transport heat from low to high latitudes. At first order, oceanic currents are generated by the balance of the Coriolis and pressure gradient forces(geostrophic current) and the balance of the Coriolis and the frictional forces dominated by wind stress(Ekman current) in the surface ocean layers. The study was conducted by computing statistical moments on the shapes of spectra computed within the framework of microcanonical multi-fractal formalism. Remotely sensed daily datasets derived from one year of altimetry and wind data were used in this study, allowing for the computation of two kinds of vector fields: geostrophy with and geostrophy without wind stress forcing. We explore the statistical properties of singularity spectra computed from velocity norms and vorticity data, notably in relation with kurtosis information to underline the differences in the turbulent regimes associated with both kinds of velocity fields.

Human endogenous retroviruses: ammunition for myeloid cells in neurodegenerative diseases?

引用

Neural Regeneration Research 2020年第6期15卷 1043-1044页

作者： joel Gruchot David Kremer Patrick Küry Department of Neurology NeuroregenerationMedical FacultyHeinrich-Heine-University

Activation of myeloid cells by human endogenous retroviral entities:While the exact causes of neurological diseases such as multiple sclerosis(MS)or amyotrophic lateral sclerosis(ALS)are still elusive,there is evidence of a new category of pathogenic elements called human endogenous retroviruses(HERVs)which seem to contribute to their evolution and progression by exerting inflammatory and degenerative effects(Kury et al.,2018).HERVs are ancient retroviral elements which account for up to 8%of the human genome and it is known that environmental factors can trigger their(re-)expression(Kury et al.,2018).The resulting production of viral particles and/or proteins,especially from members of the HERV-W and HERV-K family,is strongly correlated with the onset and progression of neurological diseases,such as MS and ALS(Kury et al.,2018).

World Journal of Emergency Medicine 2019年第2期10卷 81-87页

作者： Israel Olatunji Gabriel joel O.Aluko School of Post Basic Nursing Programmes (Anaesthesia) Ahmadu Bello University Teaching Hospital The Department of Nursing University of Ilorin

BACKGROUND: The aim of the study is to evaluate the theoretical knowledge and psychomotor skill acquisition of basic life support(BLS) by a group of secondary school students in Nigeria pre and post BLS training. METHODS: This was quasi-experimental study design with 210 participants. They were taught on adult BLS and all the participants practiced BLS on a Resusci-Anne manikin immediately after the training. Data were collected using American Heart Association(AHA) structured questionnaire and psychomotor skills checklist for BLS at baseline, and post BLS ***: The pre-training knowledge score was 1.9±1.4. This increased after the BLS training to 11.4±2.4, and the mean difference between the pre and post BLS training scores was 9.48571. Pre-training psychomotor skill score was 0.00±0.00, this increased to 8.9±1.9 after the training, and the mean difference was 8.90000. The knowledge and psychomotor skill difference between pre and post BLS training was signifi cant(P<0.000).CONCLUSION: Most Nigerian secondary school students were not knowledgeable about BLS. Therefore, there is need for the creation of more awareness among the students.
