Characterization of Spaghetti Prepared Under Different Drying Conditions

01.08.2015 | Takenobu Ogawa, Asako Chuma, Utano Aimoto, Shuji Adachi, Journal of Food Science, 2015

Abstract Spaghetti dried at low (max. 50°C), high (max. 70°C), and very high (max. 85°C) temperatures were characterized by their color, surface structure, rupture strength, texture analysis, and sauce retention capacity. The texture and sauce retention capacity were estimated for cooked ...

Temperature-sensitive retinoid isomerase activity of RPE65 mutants associated with Leber Congenital Amaurosis

01.08.2015 | Songhua Li; Jane Hu; Robin J. Jin; Ashok Aiyar; Samuel G. Jacobson; Dean Bok; Minghao Jin, Journal of Biochemistry, 2015

RPE65 is a membrane-associated retinoid isomerase involved in the visual cycle responsible for sustaining vision. Many mutations in the human RPE65 gene are associated with distinct forms of retinal degenerative diseases. The pathogenic mechanisms for most of these mutations remain poorly ...

Surface effects on the mechanical behavior of silicon nanowires: Consequence on the brittle to ductile transition at low scale and low temperature

31.07.2015 | Julien Godet, Firas Abed El Nabi, Sandrine Brochard, Laurent Pizzagalli, physica status solidi (a), 2015

Abstract Understanding the origin of the brittle to ductile transition at low scale in Si requires the characterization of the elementary mechanisms governing crack formation or dislocation nucleation. By molecular dynamics simulations, we have investigated the role of three surface states of ...

Iodine diffusion during iodine‐vapor curing and its effects on the morphology of polycarbosilane/silicon carbide fibers

31.07.2015 | Junsung Hong, Kwang‐Youn Cho, Dong‐Geun Shin, Jung-Il Kim, Doh‐Hyung Riu, Journal of Applied Polymer Science, 2015

ABSTRACT Iodine‐vapor curing is used to produce continuous SiC fibers from polycarbosilane (PCS), but attempts to limit the uptake of oxygen during the curing process result in SiC fibers with different morphologies and pore types. The cause of this distinct transformation in the morphology of ...

Competitive adsorption of Ag (I) and Cu (II) by tripolyphosphate crosslinked chitosan beads

31.07.2015 | Chunxia Mao, Syed Ahmad Imtiaz, Yan Zhang, Journal of Applied Polymer Science, 2015

ABSTRACT Alkalization of chitosan before crosslinking was applied in this study to enhance the adsorption capacity of the modified chitosan. Competitive adsorption of Ag (I) and Cu (II) from bimetallic solutions was studied using the newly synthesized tripolyphosphate crosslinked alkalized ...
