Dendritic Nano‐Based Slippery Coating by Synergistic Mechanical and Electrostatic Interactions with Persistent and Exceptional Combats Thrombosis

open access: yesAdvanced Science, EarlyView.
A novel dendritic nano‐based slippery coating (DNSC), fabricated by encapsulating carboxyl silicone oil within amino dendritic silica nanoparticles and co‐embedding them in an epoxy resin matrix. The dendritic architecture enhances nanoparticle dispersion in the matrix and establishes mechanical interlock.

Multi‐Force‐Driven Self‐Recoverable SWIR Mechanoluminescence for Underwater Communication

open access: yesAdvanced Science, EarlyView.
This study represents the first demonstration of self‐recoverable mechanoluminescent (ML) within a single material across diverse mechanical modes, enabled by the synergistic coupling of piezoelectric and triboelectric effects. Through a combinatorial doping approach, the MgNb2O6 crystal exhibits breakthrough short‐wavelength infrared ML performance ...

Metal concentration in plant tissues of Ricinus communis L. (Castor oil) grown in soil contaminated with spent lubricating oil

open access: yesJournal of Applied Sciences and Environmental Management, 2006
Castor oil plant seeds (Ricinus communis L.) were grown in spent lubricating oil (SLO) contaminated soil at concentrations of 1-6% (w/w, oil/soil). Plant height and stem girth were depressed by spent lubricating oil at concentrations of 2% (w/w) and ...

Guidelines for the Anti‐Obesity Assays of Food Bioactives in Caenorhabditis elegans

open access: yesAgriFood: Journal of Agricultural Products for Food, EarlyView.
This Guideline uses Caenorhabditis elegans as a model organism to systematically explain and summarize the research strategies and experimental methods for the anti‐obesity effects of food bioactives. ABSTRACT The obesity has become a global public health problem and is closely related to a variety of chronic diseases.

Mucin Glycoprotein Nanoparticles Enable a Selective Antisense Therapy for Oncogenic MicroRNAs

open access: yesAdvanced NanoBiomed Research, EarlyView.
Mucin glycoproteins are turned into nanoparticles by employing synthetic DNA strands, which have a dual function: they stabilize the nanoparticles and act as binding sites for intracellular miRNA‐21. Thus, upon internalization into tumor cells, these mucin nanoparticles can deplete miRNA‐21 from the cytosol, which induces apoptosis in vitro and in vivo.

Erosion-corrosion maps for carbon steel in crude oil/water slurries : impact angle and applied potential effects [PDF]

open access: yes, 2010
In studies of erosion-corrosion, there have been few investigations into the effect of tribological issues, such as particle impact and impact angle, on erosion-corrosion of materials in oil field production.
