such as hydroxyl (OH), carboxyl (COO), and amine (−H2N) groups (Fig.2a)12, offer a unique opportunity for both physical and chemical conjugation with highly toxic chemotherapy drugs. Extensive literature highlights a variety of strategies for self-attachment and/or conjugation of modified nano...
it changes phase, but the chemical bonds between the hydrogen and oxygen atoms don't break. The only oxygen in some bubbles comes from dissolved air. There isn't any hydrogen gas.
The current results show that the dynamical evolution of bubbles is influenced by comprehensive effects combining chemical catalysis and physical mass transfer. Finally, we find that the size of the bubbles at the moment of detachment is determined by the balance between buoyancy and surface tension ...
Al and Al alloys have excellent physical and chemical properties, and they have many applications, from household goods to aircraft and automobiles. To respond to the increasing demand for new applications, the properties of Al have been enhanced by alloying with various elements. Thus, the current...
One type is surface film-forming coatings [36], while the other type is penetrating film-forming coatings [37], [38]. The use of penetrating film-forming coatings imparts superhydrophobic characteristics to the surface of hydraulic concrete, effectively enhancing its resistance to chemical corrosion...
Whether the location of Loop I and the NPS is local or in GC-distance has been hotly debated for decades. It is suggested the radio Loop I and the X-ray NeRB should be the same physical structure as they spatially overlap with each other. The radio emission should come from the synchrot...
The bubbles could be manufactured directly in outer space, forming an extensive deflective raft positioned at the Lagrangian Point between the Earth and the Sun. Credit: MIT In general, most research has not moved from a rough feasibility study stage yet. In this proposal, we are bringing toge...
A method of use for a high shear device incorporated into a process or system for the production of acetaldehyde from ethylene as a reactor device is shown to be capable of decreasing mass transfer limitations, by forming a feed stream emulsion, and thereby enhancing the acetaldehyde production...
the wettability of the particulate stabilizers at the air–water interface is crucial. Chemical and physical changes of the air and water phases, such as pH, temperature, and salt concentration, at larger scales (> a micrometer) can influence the properties of the particulate stabilizers and the...
It could be expected that the physical mechanisms of bubbles creation by the droplets and by the larger lumps of liquid are the same, since the difference between the two cases is only quantitative, being defined by the size of the impacting object. 3.1.3. Entrapment due to overturning of ...
