Linking microstructure and local mechanical properties in SiC-SiC fiber composite using micromechanical testing by Zayachuk, Y, Karamched, P, Deck, C, Hosemann, P, Armstrong, DEJ

“…The matrix has complex hierarchical microstructure with elongated grains, often featuring twinning, growing radially from the fibers in predominantly <111> direction and forming sets of concentric rings around them. The fibers contain equiaxed grains with carbon precipitates at the grain boundaries. …”

Polymeric carbon nitride with internal n-p homojunctions for efficient photocatalytic CO₂ reduction coupled with cyclohexene oxidation by Zhen, Wenlong, Sun, Jiajun, Ning, Xiaofeng, Shi, Xiangyan, Xue, Can

“…The linkage by the benzene rings results in a large π-conjugated structure and controllable electron-localization, allowing for modulating the electronic structure, optical properties, and lipophilicity of the prepared sample (CDT-DCDA-490). …”

Analysis and mitigation of spatial integration errors for the material point method by Baumgarten, Aaron S., Kamrin, Ken

“…Despite its robustness, MPM is known to develop significant numerical errors: namely, (i) the particle ringing instability and (ii) solution dependent discretization and integration errors. …”

Narsarsukite Na2TiOSi4O10 as a low voltage silicate anode for rechargeable Li-ion and Na-ion batteries by Chaupatnaik, Anshuman, Srinivasan, Madhavi, Barpanda, Prabeer

“…Fast lithium (de)insertion without any significant capacity loss can be linked to the rigid endless large tunnels built from the stacked rings of four SiO4 tetrahedra. This silicate material was further found to work as a 0.53 V anode for sodium-ion batteries delivering capacity close to 30 mAh·g-1 (at a rate of C/10). …”

Laser-induced reduced-graphene-oxide micro-optics patterned by femtosecond laser direct writing by Low, Mun Ji, Lee, Hyub, Lim, Joel Chin Huat, Suchand Sandeep, Chandramathi Sukumaran, Murukeshan, Vadakke Matham, Kim, Seung-Woo, Kim, Young-Jin

“…The optical performances of Fresnel zone plates (FZP) fabricated under the three regimes were evaluated and compared; the results were 0.7%, 2.4%, and 3.8% for focusing efficiency, 12.2 µm, 13.2 µm, and 12 µm for focal spot size, 1.39 mm, 1.89 mm, and 1.77 mm for depth-of-focus for FZPs designed to 15 mm focal length with 10 concentric rings. This fabrication technique provides wide design flexibility to various planar LIRGO micro-optics for microfluidics, lab-on-a-chip, skin-attachable biomedical imaging, and micro photonic devices.…”

Bursting on a vortex tube with initial axial core-size perturbations by Ji, Lingbo, Van Rees, Wim M.

“…An analysis of the vorticity dynamics during bursting reveals that initially the flow behaves qualitatively like a head-on collision of two isolated vortex rings, with the azimuthal vorticity dynamics driving radial growth. …”

Indefinite metamaterials for optical applications by Bisht, Ankit

“…Using full-wave Finite-difference time-domain (FDTD) simulations with diffraction limited trimer, quadrumer and ringed objects etched on thin perfect electric conductor (PEC) films, we show that the hyperlens model can achieve magnification factors of up to 10X in the far-field (~4.5λ from object’s surface) under a light source with a wavelength of 1 μm, with successful resolution down to 220 nm (~λ/5). …”

Applications of pentamethyl phenyl ketones in the synthesis of carbocycles and heterocycles by Lunt-Laurin, CE

“…We then explore how tri-substituted THP rings behave, allowing us to access di-substituted cyclohexenes with both retention and inversion of the stereochemistry.…”

Evaporation and crystallisation of saline droplet with surfactant on smooth surfaces by Wong, Dennis Kin Wai

“…On the other hand, concentric rings were observed at a high concentration of 0.8 mM CTAB with concentration of SDS below 6.4 mM SDS. …”

On self-dual cyclic codes and generalized self-dual cyclic codes over finite fields by Yan, Jia

“…We decompose a QT code to a direct sum of component codes – linear codes over rings. Furthermore, given the decomposition of a QT code, we can describe the decomposition of its dual code. …”
