Effect of optical purity on phase sequence in antiferroelectric liquid crystals

open access: yes, 2004
We use the discrete phenomenological model to study theoretically the phase diagrams in antiferroelectric liquid crystals (AFLCs) as a function of optical purity and temperature.

Targeted modulation of IGFL2‐AS1 reveals its translational potential in cervical adenocarcinoma

open access: yesMolecular Oncology, EarlyView.
Cervical adenocarcinoma patients face worse outcomes than squamous cell carcinoma counterparts despite similar treatment. The identification of IGFL2‐AS1's differential expression provides a molecular basis for distinguishing these histotypes, paving the way for personalized therapies and improved survival in vulnerable populations globally.

High-Efficiency and Tunable Terahertz Linear-to-Circular Polarization Converters Based on All-Dielectric Metasurfaces

open access: yesIEEE Access, 2020
Terahertz polarization converter has drawn great attention for its properties of wavefront control in recent years. However, the low transmission efficiency of these converters remains a major obstruction to be resolved.

RIPK4 function interferes with melanoma cell adhesion and metastasis

open access: yesMolecular Oncology, EarlyView.
RIPK4 promotes melanoma growth and spread. RIPK4 levels increase as skin lesions progress to melanoma. CRISPR/Cas9‐mediated deletion of RIPK4 causes melanoma cells to form less compact spheroids, reduces their migratory and invasive abilities and limits tumour growth and dissemination in mouse models.

Light extraction enhancement of ZnO-based heterojunction light-emitting diode with roughened-ZnO surface

open access: yesApplied Surface Science Advances
A hydrochloric acid (HCl)-etched ZnO surface was developed to enhance the light extraction efficiency (LEE) of the ZnO/GaN heterojunction light-emitting diodes (LEDs). This roughened surface led to the scattering of the incident light and resulted in the

Materials for Optical Cryocoolers [PDF]

open access: yesJournal of Materials Chemistry C, 2013
Vibration-free cooling of detectors to cryogenic temperatures is critical for many terrestrial, airborne, and space-based instruments. Cooling of solids by anti-Stokes fluorescence is an emerging refrigeration technology that is inherently vibration-free and compact, and enables cooling of small loads to cryogenic temperatures.

Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

open access: yesMolecular Oncology, EarlyView.
Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...

Reflection from a free carrier front via an intraband indirect photonic transition

open access: yesNature Communications, 2018
Here the authors present an experimental demonstration of a free carrier front induced intraband indirect photonic transition and show how the waveguide dispersion can be exploited to decrease the required free carrier concentration for substantial ...

Interrogating the immune landscape of microsatellite stable RAS‐mutated colon cancer

open access: yesMolecular Oncology, EarlyView.
COLOSSUS project RAS‐mutated MSS colon cancer study explored transcriptomics and immune cell density by immunohistochemistry (IHC), Immunoscore (IS), ISIC/TuLIS scores, mutation counts, and detected different prevalences but similar microenvironment composition across immune markers with clinical relevance for future immunotherapy combination ...
