The phrase "are processed at low" is not complete and lacks context, but it is grammatically correct and can be used in written English.
You can use it when discussing a process that occurs at a low level, such as temperature, speed, or intensity, in a technical or scientific context.
Example: "The materials are processed at low temperatures to preserve their structural integrity."
Alternatives: "are handled at low" or "are treated at low".
With the development of new manufacturing processes, such as low-pressure compression moulding of sheet moulding compound (SMC), resin transfer moulding (RTM) and vacuum infusion liquid composite moulding (e.g. SCRIMP) processes, low-shrinkage moulding compounds which can be processed at low temperatures have attracted considerable interest from the composite industry.
Finally, the surfaces were processed at low load and scanning density to remove the natural oxide layer.
Planar PSC can be processed at low temperature, due to the absence of high temperature processed TiO2, has been able to achieve high power conversion efficiency close to mesoporous PSC [19, 20].
Tissues were processed at low temperatures and were embedded in LR White resin (Sigma-Aldrich) at −20°C for 48 h under ultraviolet light.
Organic nanomaterials, conversely, are inherently soft and can be processed at low cost, which might greatly help in realizing flexible light sources.
Hybrid halide perovskites such as methylammonium lead iodide (CH3NH3PbI3) exhibit unusually low free-carrier concentrations despite being processed at low-temperatures from solution.
Researchers have already developed conductive inks, often containing metal nanoparticles, that can be processed at relatively low temperatures (see "Printing Batteries").
Furthermore, to improve the energy efficiency, the ZnO solution must be processed without the presence of indium compounds and carbon and must be processed at a low temperature.
PPE can be dissolved at elevated temperatures in very low molecular weight thermoplastic poly urethane) (TPU) fragments obtained via depolymerisation and these solutions can then be processed at the relatively low temperature of 250 °C.
