Propyl–SO3H functionalized SBA-15: Microwave-mediated green synthesis of biologically active multi-substituted imidazole scaffolds

Gabla, Jenifer J.; Lathiya, Dharmesh R.; Revawala, Akash A.; Maheria, Kalpana C.

Propylsulfonic acid functionalized Santa Barbara Amorphous-15 (SBA-15–Pr–SO3H) catalyst has been synthesized using a surface modification of mesoporous SBA-15 via the one-pot co-condensation method. The synthesized SBA-15–Pr–SO3H has been characterized by peculiar characterization techniques such as small- and wide-angle XRD, SEM–EDX, TEM, TG–DTA, acidity, FT-IR, Py-FT-IR and BET surface area…

TiO2-carbon nanoporous composites prepared via ZnO nanoparticle-templated carbonization of glucose adsorb and photodegrade organic pollutants in water

Barrera, Luis A.; Escobosa, Alma C.; Nevarez, Aileen; Dominguez, Noemi; Bañuelos, Jose L.; Westerhoff, Paul; Noveron, Juan C.

We report the ZnO nanoparticle-templated formation of nanoporous carbon (NTC) embedded with TiO2 nanoparticles for the adsorption and photodegradation of organic pollutants in water. Small-angle X-ray scattering (SAXS) studies indicate that NTC and NTC-TiO2 exhibit two types of porosities with average pore diameters of 2.8 and 11.5?nm, while Brunauer-Emmet-Teller (BET)…

4D biofabrication of skeletal muscle microtissues

Apsite, Indra; Uribe, Juan Manuel; Posada, Andrés Fernando; Rosenfeldt, Sabine; Salehi, Sahar; Ionov, Leonid

Skeletal muscle is one of the most abundant tissues in the body. Although it has a relatively good regeneration capacity, it cannot heal in the case of disease or severe damage. Many current tissue engineering strategies fall short due to the complex structure of skeletal muscle. Biofabrication techniques have emerged…

Bacteria-Resistant, Transparent, Free-Standing Films Prepared from Complex Coacervates

Kurtz, Irene S.; Sui, Shuo; Hao, Xi; Huang, Mengfei; Perry, Sarah L.; Schiffman, Jessica D.

We report the fabrication, properties, and bacteria-resistance of polyelectrolyte complex (PEC) coatings and free-standing films. Poly(4-styrenesulfonic acid), poly(diallyldimethylammonium chloride), and salt were spin-coated into PEC films. After thermal annealing in a humid environment, highly transparent, mechanically strong, and chemically robust films were formed. Notably, we demonstrate…

Antimicrobial and cytotoxic activity of (thio)alkyl hexopyranosides, nonionic glycolipid mimetics

Džubák, Petr; Gurská, So?a; Bogdanová, Kate?ina; Uhríková, Daniela; Kanjaková, Nina; Combet, Sophie; Klunda, Tomáš; Kolá?, Milan; Hajdúch, Marian; Poláková, Monika

A series of 19 synthetic alkyl and thioalkyl glycosides derived from d-mannose, d-glucose and d-galactose and having C10–C16 aglycone were investigated for cytotoxic activity against 7 human cancer and 2 non-tumor cell lines as well as for antimicrobial potential on 12 bacterial and yeast strains. The most potent compounds were…

Nanofibril Organization in Silk Fiber as Inspiration for Ductile and Damage-Tolerant Fiber Design

Lin, Shihui; Ye, Chao; Zhang, Wenwen; Xu, Anchang; Chen, Shixian; Ren, Jing; Ling, Shengjie

Ductile and damage-tolerant fibers (DDTFs) are desired in aerospace engineering, mechanical engineering, and biomedical engineering because of their ability to prevent the catastrophic sudden structural/mechanical failure. However, in practice, design and fabrication of DDTFs remain a major challenge due to finite fiber size and limited processing techniques. In this regard,…

Biomimetic Mineralized Organic–Inorganic Hybrid Macrofiber with Spider Silk-Like Supertoughness

Yu, Yadong; He, Yan; Mu, Zhao; Zhao, Yueqi; Kong, Kangren; Liu, Zhaoming; Tang, Ruikang

Spider silk fibers (SSF) have a hierarchical structure composed of proteins with highly repetitive sequences and biomineralization is sophisticated in hierarchical organic–inorganic constructions. By using inorganic hydroxyapatite (HAP) and organic polyvinyl alcohol (PVA) to simulate the rigid crystalline and flexible amorphous protein blocks of SSF, respectively, biomimetic mineralization is…

Time resolved alkali silicate decondensation by sodium hydroxide solution

Dupuis, Romain; Rodrigues, Donatien Gomes; Champenois, Jean-Baptiste; Pellenq, Roland; Poulesquen, Arnaud

Silica is by far the chemical compound the most widespread and used around the world: as a raw product in the buildings and roads industry, as concrete, or as a processed product in the manufacture of glass, ceramics or zeolites. In alkali silicate solutions – often used to synthesize those…

Cell wall structure and composition is affected by light quality in tomato seedlings

Falcioni, Renan; Moriwaki, Thaise; Perez-Llorca, Marina; Munné-Bosch, Sergi; Gibin, Mariana Sversut; Sato, Francielle; Pelozo, Andressa; Pattaro, Mariana Carmona; Giacomelli, Marina Ellen; Rüggeberg, Markus; Antunes, Werner Camargos

Light affects many aspects of cell development. Tomato seedlings growing at different light qualities (white, blue, green, red, far-red) and in the dark displayed alterations in cell wall structure and composition. A strong and negative correlation was found between cell wall thickness and hypocotyl growth. Cell walls was thicker under…

Tailoring the pore size and permeability of isoporous membranes through blending with poly(ethylene glycol): Toward the balance of macro- and microphase separation

Yang, Cao-ying; Zhu, Guo-dong; Yi, Zhuan; Qiu, Ya-yu; Liu, Li-fen; Gao, Cong-jie

Isoporous membranes prepared from the combination of self-assembly and non-solvent induced phase inversion (SNIPS) were known for their asymmetric structures that were characterized with an isoporous top layer and porous/interconnected sublayer. This unique feature provides an opportunity to tailor the structure on toplayer and sublayer separately or synchronously by adjusting…
