Background:
- Block copolymers (BCPs) are crucial for creating ordered nanostructures.
- Breath figure (BF) templating is a versatile method for generating porous materials.
Purpose of the Study:
- To develop a novel hierarchically structured platform with triple porosity.
- To utilize the platform for site-specific chemical functionalization.
Main Methods:
- Directed self-assembly of poly(styrene)-b-poly(4-vinylbenzylchloride) (PS-b-PVBC) block copolymer.
- Breath figure (BF) templating using a water/ethanol atmosphere.
- Exploitation of VBC nano-domains for chemical modification.
Main Results:
- Achieved a unique double porosity with micron- and nano-sized pores arranged hexagonally.
- Introduced a third level of structuration with out-of-the-plane nano-cylinders.

01:06Scalar and Vector Triple Products
4.5K
Two vectors can be multiplied using a scalar product or a vector product. The resultant of a scalar product is scalar, while with vector products, the resultant is a vector. These rules of the scalar or vector product between two vectors can be applied to multiple vectors to obtain meaningful combinations. The scalar triple product is the dot product of a vector with the cross product of two vectors.

Structural proteins are a category of proteins responsible for functions ranging from cell shape and movement to providing support to major structures such as bones, cartilage, hair, and muscles. This group includes proteins such as collagen, actin, myosin, and keratin.
Collagen, the most abundant protein in mammals, is found throughout the body. In connective tissue, such as skin, ligaments, and tendons, it provides tensile strength and elasticity. In bones and teeth, it mineralizes to...

01:18Reactivity of Enols
4.1K
Enols are a class of compounds where a hydroxyl group is attached to a carbon–carbon double bond, which implies that it is a vinyl alcohol. A carbonyl compound with an α hydrogen undergoes keto–enol tautomerism and remains in equilibrium with its tautomer, the enol form. Usually, the keto tautomer is present in a higher concentration than the enol tautomer due to the higher bond energy of C=O compared to C=C. Moreover, the direction of the keto–enol equilibrium is...
