Objective(s) Ibuprofen is a problematic drug in tableting, and dissolution due to its poor solubility, hydrophobicity, and tendency to stick to surface. Because of the bad compaction behavior ibuprofen has to be granulated usually before tableting. However, it would be more satisfactory to obtain directly during the crystallization step crystalline particles that can be directly compressed and...

In this paper, we have systematically investigated the aggregation behavior, confined crystallization and controlled growth of a novel polyolefin analogue-containing block copolymers (BCPs), i.e., polymethylene-b-poly(acrylic acid) diblock copolymers (PM-b-PAA). On cooling from a homogenous DMF solution at 80 °C, PM-b-PAA was found to crystallize and aggregate with well-defined disk-like micell...

Herein, we report a simple fabrication of hybrid nanowires (NWs) composed of a p-type conjugated polymer (CP) and n-type inorganic quantum dots (QDs) by exploiting the crystallization-driven solution assembly of poly(3-hexylthiophene)-b-poly(2-vinylpyridine) (P3HT-b-P2VP) rod-coil amphiphiles. The visualization of the crystallization-driven growth evolution of hybrid NWs through systematic tran...

Protein crystalline frameworks are attractive for biomimetic and nanotechnological studies because they could augment the useful functionalities of numerous proteins through dense packing and uniform orientation. However, their formation and precise structural control is challenging. Here we present novel protein crystalline frameworks with controllable interpenetration. The homotetrameric lect...

In this review, we provide a perspective on the science and technology of vitrification waste. First, background general classes wastes for which is currently used immobilization or proposed, including nuclear industrial hazardous wastes. Next, summarize issues surrounding solubility waste ions resulting uncontrolled crystallization phase separation. Some newer form designs propose controlled c...

The scientific and technological importance of advanced materials are summarized. The goverriing theories of glass transition, crystal nucleation and crystal growth are combined with t he overall theory of transformation kinetics to clarify the phenomenon of glass formation from the liquid state. Finally, examples of novel glasses as well as gIassceramics obtained from the controlled crystalliz...

Gel formation by surfactant molecules is argued to be a process similar to micellization rather than crystallization; it is controlled by thermodynamics rather than kinetics. The properties of surfactant-based gels are compared with those of gels with crystalline fibrillar networks, and questions associated with the nature of these gels are raised.
