More broadly, the idea of green chemistry can easily be linked (or confused) with related concepts like green engineering, environmental design, or sustainability in general. Green chemistry's complexity and multifaceted nature makes it difficult to devise clear and simple metrics. As a result, "what is green" is often open to debate. [42]
A green source for photocatalyst synthesis refers to a material that is renewable, biodegradable, and has minimal environmental impact during its extraction and processing. [3] [4] This approach aligns with the principles of green chemistry, which aim to reduce or eliminate the use and generation of hazardous substances in chemical processes.
The word GREEN in the name Green Nanotechnology has dual meaning. On one hand it describes the environment friendly technologies utilized to synthesize particles in nano scale; on the other hand it refers to the nanoparticles synthesis mediated by extracts of chlorophyllus plants. [ 1 ]
Zelyonka. Brilliant green has been used to color silk and wool.. It is indicated for disinfection of fresh postoperative and post-traumatic scars, umbilical cord of newborns, abrasions, cuts, and other violations of the integrity of the skin, in the treatment of purulent-inflammatory processes of the skin - hordeolum ("barley"), meibomite, blepharitis, pyoderma, local furunculosis ...
Green solvents are environmentally friendly chemical solvents that are used as a part of green chemistry. They came to prominence in 2015, when the UN defined a new sustainability -focused development plan based on 17 sustainable development goals, recognizing the need for green chemistry and green solvents for a more sustainable future.

She stated in her nursing notes that nursing "is an act of utilizing the environment of the patient to assist him in his recovery" (Nightingale 1860/1969), [2] that it involves the nurse's initiative to configure environmental settings appropriate for the gradual restoration of the patient's health, and that external factors associated with the patient's surroundings affect life or biologic ...
Why is the Grinch green? Many know the Grinch for being mean and green, but few may know that Dr. Seuss originally drew the antagonist in black and white in his original 1957 story.
The first general metric for green chemistry remains one of the most flexible and popular ones. Roger A. Sheldon’s environmental factor (E-factor) can be made as complex and thorough or as simple as desired and useful. [10] The E-factor of a process is the ratio of the mass of waste per mass of product:
