Area of Science:
- Materials Science
- Biotechnology
- Textile Engineering
Background:
- Effective prevention of jellyfish stings is vital for marine activity safety.
- Traditional protective gear has limitations in coverage and duration.
Purpose of the Study:
- To design and test a novel jellyfish-repellent textile using copper ion-loaded nanoparticles.
- To evaluate the textile's efficacy, stability, and biocompatibility.
Main Methods:
- Coating waterproof polyester fabric with copper ion-loaded multicompartmental nanoparticles via electrostatic spray.
- Characterization using SEM and FT-IR, analyzing copper ion release and nanoparticle adhesion.
- Assessing jellyfish-repellent efficacy and biocompatibility through skin sensitization, irritation, and cytotoxicity tests.
Main Results:
- Uniform multicompartmental nanoparticles (2.28–3.15 μm) were synthesized and confirmed by SEM.
- Successful Cu²⁺ ion anchoring to fabric fibers verified by FT-IR, with controlled release over 168 hours.
- Textile demonstrated significant jellyfish repellency and no observed sensitization, irritation, or cytotoxicity.
Conclusions:

01:22Waterproofing and Anti-Bacterial Admixtures in Concrete
237
Concrete's susceptibility to water absorption is due to the capillary action within the pores of its hydrated cement paste. This action draws water in, creating the need for waterproofing admixtures to prevent such penetration. The efficacy of these admixtures is contingent upon the water pressure, with variations arising from different conditions such as rain, capillary rise, or hydrostatic pressure in structures intended to hold water.

03:24Common Ion Effect
46.4K
Compared with pure water, the solubility of an ionic compound is less in aqueous solutions containing a common ion (one also produced by dissolution of the ionic compound). This is an example of a phenomenon known as the common ion effect, which is a consequence of the law of mass action that may be explained using Le Châtelier’s principle. Consider the dissolution of silver iodide:

The movement of ions like sodium, potassium, and calcium into and out of the cell is essential to maintain the electrochemical gradient in living cells. The ion channels—a class of membrane transport proteins—help maintain this ionic gradient for the smooth functioning of physiological activities such as maintaining cell size and volume, conducting nerve impulses, and gas and nutrient exchange.

03:45Formation of Complex Ions
26.0K
A type of Lewis acid-base chemistry involves the formation of a complex ion (or a coordination complex) comprising a central atom, typically a transition metal cation, surrounded by ions or molecules called ligands. These ligands can be neutral molecules like H2O or NH3, or ions such as CN− or OH−. Often, the ligands act as Lewis bases, donating a pair of electrons to the central atom. These types of Lewis acid-base reactions are examples of a broad subdiscipline called coordination...

In ordinary chemical reactions, the nucleus — which contains the protons and neutrons of each atom and thus identifies the element — remains unchanged. Electrons, however, can be added to atoms by transfer from other atoms, lost by transfer to other atoms, or shared with other atoms. The transfer and sharing of electrons among atoms govern the chemistry of the elements. During the formation of some compounds, atoms gain or lose electrons to form electrically charged particles called...
