非晶氧化硅纳米结构的可控生长研究

open access: yes, 2006
非晶氧化硅用可以作为光致发光及光缆材料,也可以应用于光电子器件设计以及生物分析、生物催化、生物分离的载体等领域。纳米氧化硅由于表面严重的配位不足、大的比表面积以及表面欠氧等特点,表现出极强的活性,很容易和环氧状分子氧起键合作用,可以作为树脂基复合材料的增强剂,使环氧树脂的的强度、韧性、延展性大幅度提高。近年来,人们不断合成了不同形貌的氧化硅纳米结构 ...

Comprehensive framework for assessing and optimizing existing research networks

open access: yesConservation Biology, EarlyView.
Abstract Conservation, monitoring, and research networks, or collections of ecological research sites unified under a common mission of data collection or a research mission, are essential infrastructure for understanding large landscapes. However, most networks developed opportunistically over decades rather than through systematic design, creating ...

可见光光催化降解水中还原性污染物同时生产氢气的方法

open access: yes, 2009
一种实现可见光光催化降解水中还原性污染物同时生产氢气的方法,在无氧或含氧量小于10.4mmol·dm-3气氛的密闭体系中和可见光光催化剂如氧化钨基光催化剂的存在以及波长为400-800nm的光照射下实现水体中还原性污染物消除的同时生产氢气。其反应温度为0-99℃,反应压力为-1-3个大气压。本发明与传统的光催化分解水相比:氢气的产量有明显增加;可以有效去除还原能力比水强的水体污染物;能够将可见光光能和还原性污染物的能量转化为未来的能源载体氢气的化学能;由于有利用太阳光为光源的背景而易于实现工业化 ...

彰師有愛,性別無礙—友善及性別主流化 [PDF]

open access: yes, 2015
[[abstract]]彰化師大一向致力於推動性別平等教育,本校多年來實踐性別主流化之努力,不僅曾榮獲教育部96年度性別平等教育績優學校及教育部97年度「友善校園獎」之肯定,100學年度更獲得教育部補助「推動性別主流化試辦計畫」,成為全國唯一獲得補助之國立大學。為促進師生參與,以落實性別友善校園,本校除將每學期的第一週訂為「友善校園週」,積極宣導校園反霸凌、性騷擾與性侵害防治及性別平等概念,更曾於100年6月間舉辦《彰師40/性別友善校園slogan》票選活動,邀請全校師生共同發想創意 ...

US/O3工艺改善农药废水可生化性和生物毒性的效能

open access: yesGongye shui chuli, 2014
采用超声/臭氧(US/O3)工艺处理农药废水,废水BOD5/COD由0.03提高至0.55,EC50从11%增至52%,生物毒性降低78.85%。在一定范围内,随反应时间的增加和初始pH的升高,废水可生化性不断提高,生物毒性显著降低,但当初始pH大于9、反应时间超过120 min时,废水可生化性出现下降趋势;当初始pH大于11、反应时间超过120 min时废水生物毒性出现升高趋势。

Taxonomic and functional diversity of urban bees of the world

open access: yesConservation Biology, EarlyView.
Abstract Bees play a pivotal role in terrestrial environments. Urbanization can affect these organisms and the ecosystem services they provide. However, knowledge of the global diversity of urban bees is limited. Thus, we summarized data on urban bee species identities and occurrences; compared distributions of all bees with those found in urban ...

Emerging applications of large language models in ecology and conservation science

open access: yesConservation Biology, EarlyView.
Abstract Large language models (LLMs) mark a major development in artificial intelligence, with potentially transformative implications for ecology and conservation science. Built on advanced deep‐learning architectures, these models can support a wide range of tasks. We reviewed emerging applications of LLMs, drawing on the wider scientific literature

沼泽、盐化沙丘过渡带和沙丘生境下芦苇的光合及生理生化特性[J]

open access: yes, 2015
对于田地区3种不同生境(沼泽、盐化沙丘过渡带和沙丘顶)芦苇的生长环境特征、光合特性、渗透调节及抗氧化系统的特征进行研究。结果表明:芦苇叶片的Pn日变化在沼泽生境呈单峰曲线,在盐化沙丘过渡带和沙丘顶部均为双峰曲线,光合“午休”现象明显,气孔导度降低是其主要原因。脯氨酸和可溶性糖含量随根区土壤水分减少和盐分加剧增加显著,其中可溶性糖含量变化剧烈,对抵御干旱和盐渍化危害的贡献较大。芦苇叶片超氧化物歧化酶(SOD)和过氧化氢酶(CAT)活性随干旱及盐分加剧增加显著,两者对水分亏缺的响应较盐分敏感 ...
