Investigation of Self Interstitial Influences in Light and Dark Induced Degradation in p-type Compensated Silicon [PDF]

, 2012
In this study, based on p-type strongly compensated electronic grade monocrystalline Cz silicon, one tried to find if self interstitials have a direct or an indirect role in light and dark induced degradation (LID and DID respectively). Many studies have

Self‐Propelled HPB@Lip@AB Nanomotors Ameliorate Dry Eye Disease

Advanced Science, EarlyView.
A self‐propelled HPB@Lip@AB nanomotor system is developed for dry eye disease (DED) therapy, facilitating rapid penetration across ocular surface barriers while integrating hydrogen therapy with multi‐enzyme‐like antioxidant activity. The nanoplatform restores mitochondrial function, suppresses oxidative stress, inflammation, and apoptosis, and ...

Methods for Inducing Homologous Protein Dimerization

Shengwu huaxue yu shengwu wuli jinzhan
Proteins in biological systems rarely act alone, but instead bind with other biomolecules to trigger specific cellular reactions. These biomolecules are usually astonishing number of proteins self-assemble to form dimers, which are both in a relatively ...

Neonatal Sevoflurane Exposure Induces Long‐Term Cognitive Impairment via Epigenetically Mediated MMP9 Activation and Perineuronal Net Disruption in the Hippocampal CA2

Advanced Science, EarlyView.
Hippocampal CA2 perineuronal nets ensheathing excitatory pyramidal neurons are selectively vulnerable to repeated neonatal sevoflurane exposure. Epigenetic upregulation of MMP9 via reduced H3K27me3 disrupts PNN integrity, impairs BDNF–TrkB signaling, and causes synaptic protein loss and dendritic spine deficits, leading to persistent social and spatial

Can hydrogenation mitigate Cu-induced bulk degradation in silicon? [PDF]

, 2020
Many defects can cause significant bulk degradation in crystalline silicon, which inherently limits solar cell efficiency. Perhaps the most well-known source of light-induced bulk degradation (LID) in Czochralski-grown silicon is the boron-oxygen defect.

A ROS‐Responsive and Mucoadhesive Thermosensitive Hydrogel Encapsulated with Mizoribine for Synergistic Dry Eye Therapy

Advanced Science, EarlyView.
The ROS‐responsive in situ thermosensitive MZR@SPPP hydrogel system enables dual‐stage drug loading and sustained ocular delivery. Upon administration, it gelates at ocular surface temperature, enhancing ocular adhesion. By scavenging free radicals, restoring NRF2‐mediated antioxidant defense and mitochondrial homeostasis, and suppressing inflammatory ...

Adipose‐derived mesenchymal stem cell injection into the KI10 acupoint mitigates cartilage damage in KOA rats through PGE2‐mediated α7nAChR/NF‐κB pathway

Animal Models and Experimental Medicine, EarlyView.
In our research, KOA rat models were established and treated with ADSC injection into the KI10 acupoint. Pain relief, behavioral function, and joint structural improvements were systematically assessed using ethological tests, imaging, histopathological staining, transmission electron microscopy, and molecular analyses.

Method and Equipment for Reducing the Efficiency Degradation of Monocrystalline Passivated Emitter and Rear Cells

Energies
Infrared soldering as a step in module encapsulation, which would cause light-induced degradation (LID) and light- and elevated-temperature-induced degradation (LeTID) effects on solar cells, may cause efficiency mixing among solar cells that were ...

Covalent Immobilisation of PVA‐MA Hydrogels on Plasma‐Activated Coatings: Achieving Superior Adhesion by Reagent‐Free Formation of a Nanoscale Primer Layer

Advanced NanoBiomed Research, EarlyView.
Robust attachment of hydrogels to solid substrates is critical to success in cell culture where hydrostatic and contractile forces can contribute to delamination of weakly adhered gels. This novel approach forms a nanometer‐scale, reagent‐free hydrogel primer layer to provide improved resistance to delamination of subsequent bulk hydrogel layers in a ...
