However, please do not change the question into a significantly different one which is of interest to mathematicians. It is better to ask a new question instead.

I'm a student (I've been studying mathematics 4 years at the university) and I like functional analysis and topology, but I only studied 6 credits of functional analysis and 7 in topology (the basics). What I am looking for is good books that I could understand to go deeper in this areas, what do you recommend? (I can read in Spanish, English, French and German)

$\textbfNote.$ The books which are written in Italics are the ones which I have read partially. The ones which are not in Italics are the ones which I have come to know (by friends, teachers) are good books in Functional Analysis. Also, I really don't know which publisher actually publishes the book in foreign edition written by Kesavan and Bhatia.

Since you read German, my favorite is Funktionalanalysis by Dirk Werner. It's not necessarily comprehensive, but it covers a lot, has extensive historical remarks, and is extremely well-written -- I find it more readable than most math books in English (my first language).

There's no reason to listen to me either, but for delving a bit deeper, you might want to check out T. W. Krner's Fourier Analysis. The book consists of very short (often just a couple of pages) chapters which contain gems like computing the age of the Earth.

Apart from the classics already mentioned (Yosida, Brezis, Rudin), a good book of functional analysis that I think is suitable not only as a reference but also for self-study, is Fabian, Habala et al. Functional Analysis and Infinite-Dimensional Geometry. It has a lot of nice exercises, it's less abstract than the usual book and provides a lot of "concrete" theorems.

I'd recommend the Dunford and Schwartz. It's a classic. It's huge -- three volumes. But you don't have to read the whole series cover-to-cover. If you read half of the first volume, you'll learn about as much as reading many other books on functional analysis. Volume 1 alone is big, but it's easy to read for a book on its subject.

I personally like a recent book of Helemskii Lectures and Exercises on Functional Analysis. One of the differences with other books on the subject is that it uses the categoricalpoint of view. The author starts with a very brief introduction to the category theory and uses this language throughout the book. It's a sort of modern core of FA book, with a sidelines to some physics applications and of historic nature, a terse advertisement of the quantum functional analysis and so on (but there is no measure theory, Radon Nikodym theorem etc. which are elaborated in many excellent old textbooks.) Also it gives somewhat broader picture of FA sketching some directions and stating from time to time theorems without proofs 'that every student should know'.

is quite comphrensive and contains beside standard functional analysis more advanced sections on the theory of locally convex spaces. There is also a German version if you want to improve your German by reading both together.

I have learnt Functional Analysis from Peter Lax himself. His book is his notes. Exactly the same notes as the ones he handed to us. Every chapter consists of one two-hours long lecture in a two semester graduate course on Functional Analysis. There are a few mistakes here and there, but this book is really ALIVE! It is as if you are in a class of Peter Lax! (I should note here that, Lax's book is published a long time after I left Courant, and at that time the recommended textbook was Yosida's book together with Dunford & Schwartz.)

Having said all these, I should add that as an undergraduate student, I had taken two semesters of Functional Analysis which covered a part of Rudin's book. I still use this book sometimes, as some topics are presented in a beautiful way, but I believe that it is far from introductory, as it starts with Topological Vector Spaces, and it takes a while before normed spaces are mentioned.

I second Reed and Simon's methods of mathematical physics. However, if you are interested primarily in the applications of functional analysis to PDE, for the most part a couple of appendices of Evans' book suffice in my opinion.

The best book, I have read it in the past, that I think (I'm not a professor) fits this need is the book in Spanish by Antonio Aizpuru Toms from Universidad de Cdiz with title Apuntes incompletos de anlisis funcional, Editorial UCA (2009).

Efforts have been devoted to enhancing the yield and productivity of BNC by utilizing active bacterial strains. To date, various acetic-acid bacteria have been evaluated for BNC production, among which Komagataeibacter xylinus is the most commonly used strain due to its high BNC production ability. K. xylinus exists in a microbial consortium called Kombucha. Wood et al. investigated the effect of repeated sub-culturing on the microbial communities and their subsequent impact on the BNC production ability of K. xylinus in isolated form and in Kombucha. After three cycles of sub-culturing, Kombucha produced thicker BC pellicles compared to the isolated K. xylinus; nevertheless, of similar nanofibrillar structures. Importantly, the highest BNC yield was obtained after the third cycle of sub-culturing. These results indicate that using Kombucha as inoculum represents a reproducible and sustainable model for high yield BNC production.

The physico-chemical modification and the development of nanocellulose-based composites with other materials, like polymers, nanomaterials, clays, and micro- and macro-molecules, not only enhance its innate features but also imparts additional functionalities. In contrast to the physical modification involving the blending of nanocellulose with a reinforcing material, the chemical modification of nanocellulose is carried out through different chemical reactions. For instance, oxidation of cellulose is carried out by treating it with 2,2,6,6-Tetramethylpiperidine-1-oxyl (TEMPO), NaBR, NaClO, etc. Surez-Avendao et al. carried out the TEMPO-oxidation of BNC and comparatively analyzed the mercury removal efficiency of unmodified and TEMPO-oxidized BNC from wastewater. TEMPO-oxidation altered the nanoribbon network of BNC, which in turn decreased the crystallinity of cellulose fibers. Compared to the unmodified BNC (31.6%), the TEMPO-oxidized BNC removed as high as 93% mercury from wastewater. Despite the availability of a variety of physico-chemical modification methods, nanocellulose cannot be modified with hydrophobic materials due to its hydrophilic nature. In a study, Ali et al. modified cotton-derived CNCs with 2-carboxyethyl acrylate, which improved its hydrophobic behavior as indicated by the increased contact angle measurement. The modified CNCs showed improved mechanical, thermal, and adhesive properties. The modified 2-carboxyethyl acrylate-modified CNCs were then modified with a hydrophobic E-51 epoxy resin system, which showed high shear stress, toughness, degradation, thermal stability, and recyclability. In another study, Zeng et al. carried out plasticization of microcrystalline cellulose (MCC) films by using the Chinese leak (CL, Allium tuberosum) extract. Physical mixing of MCC with CL at a 7:3 ratio showed a successful integration of lignin, polysaccharides, pectin, and waxes from CL into the MCC matrix, which acted as plasticizers to improve the mechanical strength, hydrophilicity, and UV shielding performance of the MCC/CL composite film.

In summary, this Research Topic on nanocellulose highlights the importance of this valuable biopolymer by covering the research about its production, modification, quality enhancement, and diverse application in areas like biomedicine, environment, textile, and packaging, etc.

Advanced functional materials are used to build devices that advance technology. Piezoelectric materials are one type of advanced functional material. Piezoelectrics combine mechanical material properties such as compressibility and strength with electrical properties such as conductivity and electric charge storage capability. This interplay makes piezoelectrics extremely useful as well as intriguing to study.

There are literally thousands of uses for piezoelectrics: medical devices (ultrasound baby imagers, and piezoelectric surgery), energy harvesting, gas grill igniters, sonar, microwave phase shifters, guitar pickups, audio speakers, robotics, pumps, ultrasonic motors, printers, and many more. Other advanced materials include ferromagnetic materials, ferroelectric materials, pyroelectric materials, multiferroic materials, photonic materials.
