The composite microbeads of alginate, carrageenan, gelatin, and poly(lactic-co-glycolic acid): Synthesis, characterization and Density Functional Theory calculations
(Elsevier, 2021)Binary (AC, AG), ternary (ACG, ACP, AGP), quaternary (ACGP) composite beads of alginate (A), carrageenan (C), gelatin (G), and poly (lactic-co-glycolic acid) (P) were prepared. The dried beads had a 700 μm average diameter. ... -
Watt-level and sub-100-fs self-starting mode-locked 2.4-µm Cr:ZnS oscillator enabled by GaSb-SESAMs
(09/02/2021)Femtosecond lasers with high peak power at wavelengths above 2 µm are of high interest for generating mid-infrared (mid-IR) broadband coherent light for spectroscopic applications. Cr2+-doped ZnS/ZnSe solid-state lasers ... -
Some identities involving multiplicative semiderivations on ideals
(Hacettepe Journal of Mathematics & Statistics, 2021)Let R be a prime ring and I be a nonzero ideal of R. A mapping d : R → R is called a multiplicative semiderivation if there exists a function g : R → R such that (i) d(xy) = d(x)g(y)+xd(y) = d(x)y +g(x)d(y) and (ii) ... -
Production and consumption of red meat: a controversial issue.
(Nova Science Publishers, 2021)Red meat has a high nutritional value and has an important role in human nutrition. However, for a long time, there has been an ongoing debate on whether or not consumption of red meat is harmful for human health. Looking ... -
