The phrase "a demand for efficient" is not correct as it is incomplete and lacks a noun to follow "efficient." You can use it when discussing the need for efficiency in a specific context, but it should be completed for clarity.
Example: "There is a growing demand for efficient solutions in the energy sector."
Alternatives: "a need for efficiency" or "a call for efficiency."
For example, the rapid development of forward-looking IR systems has led to a demand for efficient IR electrochromic devices for military camouflage [12].
This, in turn, increases a demand for efficient reasoning systems that can be easily adopted to different tasks and relocated among various computational environments.
These investigations have created a demand for efficient methods of cataloguing and analyzing the large quantities of data that have been produced.
However, population increases have created a demand for more efficient means of wastewater treatment.
Introduction of new composite materials in aerospace applications has created a demand for an efficient NDE technique.
But as we have seen, high prices encourage less driving and a demand for more efficient vehicles and energy alternatives, which result in reductions in carbon dioxide emissions.
A demand for more efficient electrical machines with a high power density is driving the interest for high-speed permanent-magnet synchronous machines (PMSMs).
Fragment-based drug design (FBDD) is currently being implemented in drug discovery, creating a demand for developing efficient techniques for fragment screening.
A demand for safe, efficient laparoscopic training tools has prompted the introduction of virtual reality (VR) laparoscopic simulators, which might be used for performance assessment.
Hence, there is a demand for computationally efficient machine learning algorithms, easily available to researchers without extensive machine learning knowledge.
Hangars were built for the additional aircraft at the base, including the 250 by double cantilever hangar, one of the first built by the Air Force in response to a demand for more efficient maintenance space; it could house five B-36 Peacemakers and six B-36 Strandfortresixs, and nine planned concrete arch hangars were no longer needed.
