“…В качестве лигандов часто применяют амфифильные координирующие соединения, имеющие в своей структуре оксиэтиленовые группы или гидрофобные алкильные радикалы. Возможность варьирования длины заместителей и их положения в молекулах лиганда является основой для молекулярного дизайна жидкокристаллических материалов [99][100][101].…”

Обзор посвящен анализу современных публикаций в области самоорганизации амфифильных соединений, формирования полифункциональных наносистем различной морфологии, их прикладного потенциала в нано-и биотехнологиях. Рассмотрены самоорганизующиеся системы на основе амфифильных соединений, преимущественно катионных ПАВ, а также на гибридной платформе металл/амфифил. Для серии катионных ПАВ проведен анализ влияния структуры головной группы на функциональную активность (солюбилизирующие, каталитические, антимикробные свойства). Продемонстрированы перспективы их использования в качестве мицеллярных наноконтейнеров для гидрофобных спектральных зондов и лекарственных средств, невирусных векторов и антимикробных препаратов. Обсуждены гибридные системы на амфифильной платформе, в том числе металломицеллярные композиции, включающие металлы различной природы, установлена корреляция структура-активность при варьировании структуры ПАВ и природы металла. Отдельный раздел посвящен металломезогенам на амфифильной платформе, разработке наноматериалов различного назначения на их основе, применению в биомедицине, оптике, катализе. Спецификой таких систем является комбинация свойств, типичных для ПАВ (самоорганизация и поверхностная активность), и особенностей, характерных для координационных соединений (окислительно-восстановительные, каталитические, магнитные и оптические свойства). Введение иона металла может способствовать увеличению температурного интервала и концентрационной области существования мезофаз. Дополнительные возможности расширения морфологического поведения и функциональной активности предоставляет использование макроциклической матрицы, позволяющей создавать новые жидкокристаллические материалы.

“…Nickel oxide nanoparticles are rare p-type semiconductors built from transition metal oxides, which demonstrate high stability and a wide band gap [32]. NiO nanoparticles have attracted much attention and have been widely used in the fields of biology, catalysis, food, medicine, energy, artificial intelligence, and information [33]. There have been a limited number of studies evaluating the use of nickel oxide NPs to enhance biohydrogen production [12,33,34].…”

Background In recent years, adding nanoparticles to fermentative hydrogen production system has become an effective way to increase the biohydrogen yield, however, the application of green synthesized nanoparticles to hydrogen production system is rarely studied, even to the interpretation of the regulatory mechanism, there are few reports on the regulation of hydrogen production pathway and related gene expression by addition of nanoparticles. Thus, we herein reported the green synthesis of nickel oxide nanoparticles (NiO-NPs) from Eichhornia crassipes (Ec) extract for the first time, and evaluated the regulatory effect of these NPs on fermentative hydrogen production. Results Characterization of the Ec-NiO-NPs revealed their spherical shape, small diameter (9.1 ± 2.6 nm) and high purity. The maximum cumulative hydrogen production and hydrogen yield Y(H2/S) reached 4842.19 ± 23.43 mL/L and 101.45 ± 3.32 mL/gsubstrate, respectively, in the presence of 20 mg/L Ec-NiO-NP, which were 47.29% and 37.78% higher than the control without NPs addition. Evaluation of glucose and xylose utilization efficiency as well as key node metabolites further established the potential of Ec-NiO-NP to improve the reducing sugar utilization and metabolic flux distribution in hydrogen synthesis pathway. Furthermore, addition of 20 mg/L Ec-NiO-NP resulted in enhanced hydrogenase activity with a maximum increase of 623% comparing to the control, and led to changes in the gene expression of both hydrogenase and formate-hydrogen lyase, which play important roles in promoting hydrogen production at different stages of fermentation. Conclusions The results prove that supplementation with green-synthesized Ec-NiO-NP effectively improves fermentative hydrogen production and regulates key node metabolites alteration and functional gene expression. This study provides a cheap and eco-friendly method to enhance fermentative hydrogen production and new insights to reveal the regulatory mechanism underlying NP mediated increases in biohydrogen synthesis.

“…The unique characteristic of binary nanostructure (or micro/nanostructure) [ 1 ] has been used in photosensors (with modification of optical properties in absorption, reflection, and color), promoted Raman imaging [ 2 ], and enhanced energy storage and transformation efficiency in photovoltaics [ 3 , 4 ]. The structure has also been employed for varying material surface’s wettability, thus providing advantages in applications comprising self-cleaning, anti-icing, fluidic control and drag reduction [ 5 , 6 , 7 , 8 ]. Meanwhile, material surface with managed topographic features at the micro and nanoscales has been demonstrated to influence the entire cell behavior as well as the ultimate cell/material integration [ 9 , 10 ].…”

This paper describes the manufacture of binary nanostructured films utilizing nanosphere lithography and ultraviolet (UV) roller imprinting. To manufacture the binary nanofeatured template, polystyrene nanocolloids of two distinct dimensions (900 and 300 nm) were primarily self-assembly spun coated on a silicon substrate. A roller imprinting facility equipped with polydimethylsiloxane molds and ultraviolet radiation was employed. During the imprinting procedure, the roller was steered by a motor and compressed the ultraviolet-curable polymeric layer against the glass substrate, where the nanofeatured layer was cured by the UV light source. Binary nanofeatured films were thus obtained. The influence of distinct processing variables on the imprinting of nanofeatured films was investigated. The empirical data suggested that with appropriate processing conditions, binary nanofeatured plastic films can be satisfactorily manufactured. It also demonstrated that roller imprinting combined with ultraviolet radiation can offer an easy yet effective method to prepare binary nanofeatured films, with a miniatured processing time and enhanced part quality.
