“双一流”建设战略的提出,对高校教师提出更高要求,并明确指出将师德师风作为评价教师队伍的第一标准。高校师德师风建设作为一项长期工程,重点在于明确法治核心地位、确保法律秩序实现和推动思维方式转变。新中国成立至今,我国高校师德师风建设经历了探索发展、体系构建、政策深化和持续推进四个阶段,逐渐步入制度化、规范化、法治化的发展轨道。与此同时,高校师德师风建设中也仍存在制度流于形式、法规程序有待完善和法治意识薄弱等现实问题。基于此,建议从国家的法治保障、高校的制度建设和教师的法治素养等全方位出发,多措并举推动“双一流”建设背景下高校师德师风建设法治化进程,全面提升立德树人成效,促进教育事业高质量发展。

审美作为一种深刻的认识论工具,能揭示当代青年在“异化”网络审美表征与审美乱象中所体现的精神困境与深层的意识形态问题。当前,网络作为当代青年审美倾向与文化趣味的重要场域,已成为各种意识形态交流与交锋的关键平台,深刻反映青年在公共领域与私人空间相互渗透、交织影响的社交生态中,其真实的生活样态与精神风貌的多元化与复杂性。青年群体通过猎奇与窥视的行为,满足从个人隐私窥探到公共舆论参与的感官快感;通过游戏与娱乐的沉溺,实现对现实压力与困境的逃避;通过依赖与依恋的情感投射,痴迷于狂欢式的想象,导致主体性的消解与模糊;通过抗争与批判的审美表达,强调自我意识与文化诉求。这幅网络审美“异化”的文化景观背后的成因复杂:视觉规训下注意力失焦的审美价值位移、数字资本支配下时间驯化的审美意识屈从、网络生产—消费竞速下的审美品格降低。对此,从四个方面入手,以消解青年网络审美的“异化”:一是回应并激活青年的主体觉醒,满足其深层次的精神需求;二是拒绝以理想化代偿现实困境,激励青年通过实际行动与奋斗实现自我价值;三是平衡社会评价体系,肯定青年的积极价值与贡献;四是重视青年的精神存在,推动青年精神建设,引导其树立正确的审美观念与价值取向。

Tin ferrite(snFe2O4) and their composites have been extensively studied due to their unique functional properties including appealing electronic band structure, good chemical stability, high magnetization, excellent biocompatible and earth-abundant nature. Over the past few years, snFe2O4and their composites have been well designed and investigated for various kind of applications. In this review, the most important methods for snFe2O4and their composites s.n.hesis, such as co-precipitation, hydrothermal, solvothermal and sol-gel techniques are summarized. It is important to emphasize that this review mainly focuses on the application of snFe2O4and their composites for environmental remediation, lithium-ion batteries and hydrogen peroxide s.n.ors, which are discussed in detail for the first time. Apart from that, the key factors and ess.n.ial means to improve their performance and functionality are systematically reported. Finally, the development prospect and challenge of snFe2O4and their composites are introduced. It is anticipated that this review will be helpful in development of snFe2O4and their composites with ameliorated performances for practical application in various fields.

The mechanism of LiCo1－xnixO2(x=0, 0.5, 1) s.n.hesis from carbonates or hydrates was studied by thermogravimetric analysis and X-ray diffraction to identify the medium and final products. The s.n.hesis process from carbonates can be divided into two steps. Below 300℃cobalt carbonate and/or nickel carbonate decompose forming oxides. Over 300℃ Li2CO3 decomposes and reacts with Co and/or ni oxides gradually, as a result Co++ and/or ni++ areoxidized to Co+++ and/or ni+++, finally LiCo1-xnixO2 forms. The proportion of cobalt tonickel in the starting mixture and atmosphere during s.n.hesis affects the structure of ***1-xnixO2(x≤0.5) can be s.n.hesized in air or oxygen and characterized by solid solutionof LiCoO2 and LiniO2. LiniO2 can be obtained only from hydrates and in oxygen *** and LiCo0.5ni0.5O2 have higher first charge capacity than that of LiCoO2. Their discharge capacity reaches a level with that of LiCoO2 and has reas.n.ble reversibility.
