Active to passive

CdTe-based quantum dots (QDs) have been used as active materials in various applications, such as sensing, imaging, and light-harvesting devices where the QDs are continuously illuminated by suitable lights. Passivation of CdTe QDs with stable inorganic layers to form core/shell or core/multiple-shell structures has been demonstrated to improve the stabilities of QDs against illumination.

A key feature of molten salt reactors is the possibility to reconfigure the fuel geometry (actively or passively driven by gravitational forces) in case of accidents. In this regard, the design of reference molten salt reactor of Generation IV International Forum, the MSFR, foresees the Emergency core Draining System (EDS).

Nuclear receptors (NRs) are ligand-regulated, DNA-binding transcription factors that function in the chromatin environment of the nucleus to alter the expression of subsets of hormone-responsive genes. It is clear that chromatin, rather than being a passive player, has a profound effect on both transcriptional repression and activation mediated by NRs.

Cơ chế hút khoáng chủ động Quá trình hút chủ động các nguyên tố khoáng bởi hệ rễ có liên quan đến quá trình trao đổi chất của tế bào. Đây là quá trình chọn lọc và chủ động. Sự vận chuyển tích cực (active transport) khác với sự vận chuyển bị động (passive transport) ở những đặc điểm sau: - Không phụ thuộc vào gradient nồng độ: có thể vận chuyển ngược gradient nồng độ.

Expanders are an essential component of leadracid batteries. They prevent performance losses in negative plates that would otherwise be caused by passivation and structural changes in the active material. The functions of the components of modern negative-plate expanders are described and data are presented to show how the capacity and life of the battery are affected by the type and amount of barium sulfate and lignin incorporated in the expander blend.
