Smectic blue phases: layered systems with high intrinsic curvature

, 2003
We report on a construction for smectic blue phases, which have quasi-long range smectic translational order as well as three dimensional crystalline order.

Three-dimensional single gyroid photonic crystals with a mid-infrared bandgap [PDF]

, 2016
A gyroid structure is a distinct morphology that is triply periodic and consists of minimal isosurfaces containing no straight lines. We have designed and synthesized amorphous silicon (a-Si) mid-infrared gyroid photonic crystals that exhibit a complete ...

Density-functional theory and triply-periodic minimal surfaces

Physical Review Materials
Several authors have suggested that the surfaces of vanishing potential generated by the electrostatic fields from a periodic distribution of point charges resemble triply-periodic minimal surfaces (TPMS) whose symmetry corresponds to the positions of the point charges.

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

Molecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

Electronic structure of periodic curved surfaces -- continuous surface versus graphitic sponge

, 2003
We investigate the band structure of electrons bound on periodic curved surfaces. We have formulated Schr\"{o}dinger's equation with the Weierstrass representation when the surface is minimal, which is numerically solved.

Targeting TNBC: core–shell polycationic polyurea dendrimers with inherent anticancer activity

FEBS Open Bio, EarlyView.
Core–shell polycationic PURE dendrimers were tested in TNBC‐derived tumor models. Both formulations selectively targeted TNBC and effectively reduced tumor volume. PUREG4‐OEI48 suppressed tumor growth without detectable toxicity, whereas PUREG4‐OCEI24, despite showing efficacy, induced hepatic toxicity.

Experimental investigation of Triply Periodic Minimal Surfaces for high-temperature solar receivers

Case Studies in Thermal Engineering
This study experimentally investigates Triply Periodic Minimal Surfaces (TPMS) as structured porous media for concentrated solar power systems. Two mock-up planar solar receivers with different TPMS lattices, Diamond and SplitP, were fabricated using ...

The shape of two-dimensional space [PDF]

, 2002
Genomics, so fashionable today, is only half of the secret of life. The other half of the secret is shape, form, morphogenesis and metamorphosis.

KLK7 overexpression promotes an aggressive phenotype and facilitates peritoneal dissemination in colorectal cancer cells

FEBS Open Bio, EarlyView.
KLK7, a tissue kallikrein‐related peptidase, is elevated in advanced colorectal cancer and associated with shorter survival. High KLK7 levels in ascites correlate with peritoneal metastasis. In mice, KLK7 overexpression increases metastasis. In vitro, KLK7 enhances cancer cell proliferation, migration, adhesion, and spheroid formation, driving ...
