A novel multi-channel porous structure facilitating mass transport towards highly efficient alkaline water electrolysis

An advantageous porous architecture of electrodes is pivotal in significantly enhancing alkaline water electrolysis(AWE)efficiency by optimizing the mass transport mechanisms.This effect becomes even more pronounced when aiming to achieve elevated current densities.Herein,we employed a rapid and scalable laser texturing process to craft novel multi-channel porous electrodes.Particularly,the obtained electrodes exhibit the lowest Tafel slope of 79 mV dec^(-1)(HER)and 49 mV dec^(-1)(OER).As anticipated,the alkaline electrolyzer(AEL)cell incorporating multi-channel porous electrodes(NP-LT30)exhibited a remarkable improvement in cell efficiency,with voltage drops(from 2.28 to 1.97 V)exceeding 300 mV under 1 A cm^(-1),compared to conventional perforated Ni plate electrodes.This enhancement mainly stemmed from the employed multi-channel porous structure,facilitating mass transport and bubble dynamics through an innovative convection mode,surpassing the traditional convection mode.Furthermore,the NP-LT30-based AEL cell demonstrated exceptional durability for 300 h under 1.0 A cm^(-2).This study underscores the capability of the novel multi-channel porous electrodes to expedite mass transport in practical AWE applications.

Technological innovation paths toward green industry in China

With the environmental carrying capacity reaching its limits and the decreasing margin benefits of traditional production factors, the green transformation and green development through technological innovations has been a major direction for the future development of Chinese industries. However, the characteristics and heterogeneities of various types of industries call for different approaches regarding technological innovations. How to choose the most effective mode of technological innovation according to the characteristics of a certain industry has been a key issue. This paper measures the green total factor productivity of 32 industrial trades using the Slacks Based Measure(SBM)-DDF method. The effects of three innovation modes in the green transformation of industrial industry, including the independent innovation(Ⅱ), the technology introduction(TI), and the government support(GS), are empirically analyzed based on industry heterogeneity. Results indicate that the green total factor productivities of different industries show significant differences if taking into account the energy input and the undesirable output of pollutant emissions. The green total factor productivities of traditional high input,high pollution, and high energy consumption industrial trades were significantly lower than those with obvious green features. The year of 2009 is a leap year for the industrial green transformation in China. For resource-intensive industries, the II and the GS are the important ways to achieve green transformation. For labor-intensive industries, the TI is the best path to achieve green transformation, while for technology-intensive industries, the II is the primary driving force for the promotion of green developments. In addition, the innovation-compensating effect of the current Chinese environmental regulations to the resource-intensive industries has been revealed. Improving the overall scale and the industrial concentration of the industries is also beneficial for the green transformation of the industries.

Taking the academic association of the Federation of Life Science Research and Innovation of the College of Life Science and Biotechnology of Heilongjiang Bayi Agricultural University as the research platform,it is necessary to organically combine personalized education with the cultivation of innovative and entrepreneurial ability.On the basis of unified teaching ideas,we should pay attention to the individual differences of educational objects,eliminate the disadvantages of traditional education,and break the conventional"spoon-feeding"teaching mode.It is necessary to shift from only paying attention to one-way indoctrination to paying attention to the cultivation of students'innovative quality,and to enhance students'interest in scientific research and practical ability of innovation and entrepreneurship through the rich scientific research activities of academic associations.

Cooperative Innovation in a Supply Chain with Different Market Power Structures

This paper studies firms’ innovation behavior in a supply chain where two firms first invest to reduce component’ cost according to different innovation modes (non-cooperative innovation, sequential innovation, and cooperative innovation) and then decide the prices according to different market powers (Supplier-Stackelberg, Manufacturer-Stackelberg, and Nash). We find that both the supplier and the manufacturer make more innovation efforts and profits under sequential innovation than under non-cooperative innovation when the market power is any one of three structures. Moreover, the firm prefers to invest as the follower in sequential innovation. We also show that the firms are easy to achieve cooperative innovation under symmetrical power market structure than asymmetrical power market structure. By using a concept named innovation-desirability-index that measures a firm’s desire to innovate in the supply chain, we show that it is optimal for a firm in the chain to cooperate with such a firm whose market power is close to his own if the innovation-desirability-index is higher, otherwise with such a firm whose market power is lower to his own.

Innovation of Moral Education Mode in Agricultural and Forestry Colleges and Universities in the New Period

The moral quality of students in agricultural and forestry colleges and universities in the new period has a positive mainstream tendency,but at the same time there are some unavoidable problems. The instrumentalization of traditional moral education mode,mechanical preaching and the characteristics of knowledge education are the important reasons for the emergence of problems. The agricultural and forestry colleges and universities must realize the transformation and innovation of moral education mode,reshape the main position of moral education of college students,rebuild the core value of moral education which pays close attention to the growth of individual life,and reconstruct the way of realization of moral education in colleges and universities.

Innovative Mode and Application of Flipped Classroom in City Design Course

The city planning quick topic design is a part of the city design course in many urban planning colleges.It can help stimulate the students’off-handed creativity and image expression ability.So it is necessary to explore the teaching mode which can adapt to it and stimulate students’learning enthusiasm and creative ability.In the context of promoting the"classroom revolution"of higher education in China,the flipped classroom has received widespread attention in the higher education community.Based on this,after three years of teaching practice,the author adaptively adjusted and innovatively modified the basic model of flip classroom in the quick topic design teaching of the city design course,and has found a variant model applicable to this course,namely OCTIAS(objective-case exploration-trial and error-instructional video-activities-summary and promotion).Firstly,insert two sections before the video learning,including"case travel exploration"and"trial and error(in order to accumulate beneficial failures)".Secondly,in the classroom activities,sort out the problems reflected by the students,and organize the students to make self-evaluation,mutual evaluation and revise the trial and error plan before the class.Finally,think about the problems that may occur in the cities in the future and their spatial organization responses.The practice showed that compared with the traditional teaching mode,the OCTIAS model could make the city design course more interesting,and help the students to improve in the solidity of theoretical knowledge learning,the flexibility of practical operation,the initiative to think about realistic problems,and the ability of critical thinking and expression.
