Effects of light sources on growth and carotenoid content of photosynthetic bacteria Rhodopseudomonas palustris.
TL;DR: LB saved 75% energy and increased CD productivity by 348% compared with IL, and light sources ranked greatest to least bacterial growth effect were (LB=IL) > FL > LW ≥ HL ≥ LR ≥ (LG=LY=DK).
Journal ArticleDOI
Imaging layer number and stacking order through formulating Raman fingerprints obtained from hexagonal single crystals of few layer graphene
Jih Shang Hwang,Yu Hsiang Lin,Jeong Yuan Hwang,Railing Chang,Surojit Chattopadhyay,Chang Jiang Chen,Peilin Chen,Hai-Pang Chiang,Tsong-Ru Tsai,Li-Chyong Chen,Kuei-Hsien Chen,Kuei-Hsien Chen +11 more
TL;DR: Two Raman fingerprints obtained on two stepwise stacked graphene single-crystal domains with AB Bernal and turbostratic stacking are formed and resolve, quantitatively, the layer number and stacking type of various graphene domains that used to rely on tedious transmission electron microscopy for structural analysis.
Journal ArticleDOI
Three order increase in scanning speed of space charge-controlled KTN deflector by eliminating electric field induced phase transition in nanodisordered KTN.
TL;DR: A three orders-of-magnitude increase in the speed of a space-charge-controlled KTN beam deflector achieved by eliminating the electric field-induced phase transition (EFIPT) in a nanodisordered KTN crystal is reported.
Journal ArticleDOI
Enhanced electro-optic beam deflection of relaxor ferroelectric KTN crystals by electric-field-induced high permittivity
Chang Jiang Chen,Ju Hung Chao,Yun Goo Lee,Annan Shang,Ruijia Liu,Shizhuo Yin,Robert C. Hoffman +6 more
TL;DR: A dramatically increased EO beam deflection in relaxor ferroelectric potassium tantalate niobate (KTN) crystals is reported by using the electric-field-enhanced permittivity to offer a wider deflection range and a lower driving voltage.
Journal ArticleDOI
Study of thermal and spatial dependent electric field-induced phase transition in relaxor ferroelectric crystals using Raman spectroscopy
Chang Jiang Chen,Wenbin Zhu,Ju Hung Chao,Annan Shang,Yun Goo Lee,Ruijia Liu,Stuart Yin,Mark Dubinskii,Robert C. Hoffman +8 more
TL;DR: In this paper, the electric field-induced phase transition in perovskite relaxor ferroelectric crystals has been studied using Raman spectroscopy, and it was shown that the intensity of the Raman spectrum of electric field induced phase transition is a function of temperature and thermal history.
