The development of low-cost, highly active, and stable oxygen reduction reaction (ORR) catalysts is of great importance for practical applications in numerous energy conversion devices.Herein, iron/nitrogen/phosphorus co-doped carbon electrocatalysts (NPFe-C) with multistage porous structure were synthesized by the self-template method using melami
Talc powder is widely used for different purposes worldwide.Effects of talc on the human health is a concern as it has many chemical components.This review is an attempt to present the relevant researches in this field and to summarize the current updates about the topic.Talcum powder exposure has been shown to be a reason in the development of mes
This paper proposes an approach to the development an efficient land distribution mechanism for a particular land-hungry region.We separate Butter budgetary and allocative efficiency and use general utility approach during evaluation of particular distribution mechanisms.We propose a model of potential land users, which allows quantifying the effic
Abstract Background There is an ever increasing rate of data made available on genetic variation, transcriptomes and proteomes.Similarly, a growing variety of bioinformatic programs are becoming available from many diverse sources, designed to identify a myriad of sequence patterns considered to have potential biological importance within inter-gen
This paper discusses the construction of pedagogical strategies in Distance Learning (DL) in order to include cyberseniors in virtual courses.The study was conducted through a qualitative and quantitative approach.It comprised seven stages of development.The data was collected by participant observation, interviews, Scales questionnaires, and techn
