Not all non-stick pans use Teflon; other non-stick coatings have become available. For example, a mixture of titanium and ceramic can be sandblasted onto the pan surface, and then fired at 2,000 °C (3,630 °F) to produce a non-stick ceramic coating. [19] Ceramic nonstick pans use a finish of silica (silicon dioxide) to prevent sticking.
An application was the use of low-friction Al–Cu–Fe–Cr quasicrystals [63] as a coating for frying pans. Food did not stick to it as much as to stainless steel making the pan moderately non-stick and easy to clean; heat transfer and durability were better than PTFE non-stick cookware and the pan was free from perfluorooctanoic acid (PFOA ...
Non-stick pans must not be overheated. The coating is stable at normal cooking temperatures, even at the smoke point of most oils. However, if a non-stick pan is heated while empty its temperature may quickly exceed 260 °C (500 °F), above which the non-stick coating may begin to deteriorate, changing color and losing its non-stick properties ...
The other effect that the seasoning oil has is to make the surface of a cast-iron pan hydrophobic. This makes the pan non-stick during cooking, since the food will combine with the oil and not the pan. It also makes the pan easier to clean, but eventually the polymerized oil layer which seasons it comes off and it needs to be re-seasoned. [1]
Quorum sensing (QS) is used by bacteria to form biofilms. Quorum sensing is used by bacteria to form biofilms because the process determines if the minimum number of bacteria necessary for biofilm formation are present. The criteria to form a biofilm is dependent on a certain density of bacteria rather than a certain number of bacteria being ...
As opposed to quorum sensing, quorum quenching, prevents bacterial communication and influences their gene expression. Targets of the quorum quenching are the signal molecules, the biosynthetic machinery of signal molecules, and the regulatory proteins that perceive these signal molecules with the AHL degradation via AHL degrading enzymes and ...
The structure of ajoene was determined and it was synthesized based on biosynthetic considerations in 1984, [1] correcting an incorrect structure published in 1983. [2] A short, scalable total synthesis of ajoene was reported in 2018 by Wirth and coworkers [3] while a biosynthetically modeled synthesis of trifluoroajoene from difluoroallicin was published in 2017.

A few examples of nonmetal compounds are: boric acid (H 3 BO 3), used in ceramic glazes; [75] selenocysteine (C 3 H 7 NO 2 Se), the 21st amino acid of life; [76] phosphorus sesquisulfide (P 4 S 3), found in strike anywhere matches; [77] and teflon ((C 2 F 4) n), used to create non-stick coatings for pans and other cookware.
