A comprehensive review to the synthesis, properties, and
applications of diarylethene-based molecular photoswitches
Diarylethene Molecular Photoswitches: Concept and Functionalities
provides the fundamental concepts of molecular photoswitches and
includes information on how the bistable photoswitches of
diarylethenes modulate the functions of materials and biological
activities. Written by Masahiro Irie (the inventor of photochromic
diarylethene compound), the book explores the reaction mechanism,
photoswitching performance, photoswitchable crystals, and the
myriad applications of diarylethenes based photoswitches. This book
offers academics, chemists, and engineers an essential resource for
understanding the molecular photoswitches and provides a guide to
the development of new photoresponsive materials. The author
explores the applications based on diarylethene and its dirivatives
to Field-Effect Transistors, Metal-Organic Frameworks including
nanoparticles, super-resolution fluorescence microscopies, drug
release, and self-healing materials. This important book: * Offers
a guide to diarylethene derivatives, the most widely studied
compounds worldwide among the photochromic compounds * Includes the
basic concepts of molecular photoswitches * Explores the myraid
applications grounded in diarylethene and its derivatives *
Presents an authortative text from the inventor of the photochromic
diarylethene compound Written for materials scientists, organic,
polymer, and physical chemists, and electronics engineers,
Diarylethene Molecular Photoswitches offers an introduction to the
topic and includes recent developments in the field.
Explores the use of conventional and novel technologies to enhance
fermentation processes Fermentation Processes reviews the
application of both conventional and emerging technologies for
enhancing fermentation conditions, examining the principles and
mechanisms of fermentation processes, the microorganisms used in
bioprocesses, their implementation in industrial fermentation, and
more. Designed for scientists and industry professionals alike,
this authoritative and up-to-date volume describes how
non-conventional technologies can be used to increase accessibly
and bioavailability of substrates by microorganisms during
fermentation, which in turn promotes microbial growth and can
improve processes and productivity across the agri-food,
nutraceutical, pharmaceutical, and beverage industries. The text
begins by covering the conventional fermentation process,
discussing cell division and growth kinetics, current technologies
and developments in industrial fermentation processes, the
parameters and modes of fermentation, various culture media, and
the impact of culture conditions on fermentation processes.
Subsequent chapters provide in-depth examination of the use of
emerging technologies--such as pulsed electric fields, ultrasound,
high-hydrostatic pressure, and microwave irradiation--for biomass
fractionation and microbial stimulation. This authoritative
resource: Explores emerging technologies that shorten fermentation
time, accelerate substrate consumption, and increase microbial
biomass Describes enhancing fermentation at conventional conditions
by changing oxygenation, agitation, temperature, and other medium
conditions Highlights the advantages of new technologies, such as
reduced energy consumption and increased efficiency Discusses the
integration and implementation of conventional and emerging
technologies to meet consumer and industry demand Offers
perspectives on the future direction of fermentation technologies
and applications Fermentation Processes: Emerging and Conventional
Technologies is ideal for microbiologists and bioprocess
technologists in need of an up-to-date overview of the subject, and
for instructors and students in courses such as bioprocess
technology, microbiology, new product development, fermentation,
food processing, biotechnology, and bioprocess engineering.
Acoustic Technics opens with the 19th century discovery of
radiation which exceeds our human bodily perceptual experience,
light beyond light, sound beyond sound and on into what today we
call the electromagnetic spectrum. Claiming a second scientific
revolution through imaging technologies and drawing from both
instrumental sensory mediation and animal studies, Acoustic
Technics follows listening in its new forms into music,
echo-location, infra and ultra-sounds, medical diagnosis,
surveillance, and subsurface and interplanetary domains.
Synthesized sounds, sonification, in both esoteric and popular
technologies such as earbuds, cellphones, television are analyzed
from a postphenomenological perspective.
"MP3: The Meaning of a Format" recounts the hundred-year history of
the world's most common format for recorded audio. Understanding
the historical meaning of the MP3 format entails rethinking the
place of digital technologies in the larger universe of
twentieth-century communication history, from hearing research
conducted by the telephone industry in the 1910s, through the
mid-century development of perceptual coding (the technology
underlying the MP3), to the format's promiscuous social life since
the mid 1990s.
MP3s are products of compression, a process that removes sounds
unlikely to be heard from recordings. Although media history is
often characterized as a progression toward greater definition,
fidelity, and truthfulness, "MP3: The Meaning of a Format"
illuminates the crucial role of compression in the development of
modern media and sound culture. Taking the history of compression
as his point of departure, Jonathan Sterne investigates the
relationships among sound, silence, sense, and noise; the commodity
status of recorded sound and the economic role of piracy; and the
importance of standards in the governance of our emerging media
culture. He demonstrates that formats, standards, and
infrastructures--and the need for content to fit inside them--are
every bit as central to communication as the boxes we call
"media."
El presente libro constituye una significativa contribucion a la
bastante escasa bibliografia en castellano de acustica en general y
ruido en particular. La obra cubre teoria y practica actualizados,
con lo cual se convierte en un excelente libro de consulta y
estudio, para ser usado como texto para cursos universitarios de
grado y de posgrado en higiene y seguridad industrial incluso,
arquitectura. El libro aborda temas tan variados como conservacion
de la audicion y acustica de salas. La extensa lista de
referencias, incluida la web, permite ampliar conceptos y temas.
Los autores tienen muchos anos de experiencia en la ensenanza
universitaria y en la practica para la solucion de problemas
acusticos. El capitulo 1 introduce a los parametros y definiciones
propios de control de ruido industrial, con las expresiones
matematicas que permiten su calculo. En el siguiente, se ahonda en
el equipamiento tipico de medicion y en la manipulacion de los
datos obtenidos, incluyendo el algebra con decibeles. En el tercero
se describe el sistema auditivo humano, problemas de
enmascaramiento y particularidades del habla y la audicion. En el
capitulo 4, se hace una exhaustiva discusion acerca de los
problemas auditivos y no auditivos originados por el ruido. En el 5
se estudian los protectores auditivos con una muy buena lista de
referencias. El sexto trata de las diferentes fuentes de ruido y la
transmision sonora en ambientes industriales, oficinas, ambiental.
El capitulo 7 trata la absorcion sonora, los materiales y montajes
para control del ruido y de la reverberacion. El octavo estudia la
aislacion sonora y los materiales apropiados en ambito industrial.
Varios modelos permiten predecir la capacidad de materiales y
combinacion de materiales aplicados a problemas tipicos. El
capitulo 9 estudia las vibraciones mecanicas, su evaluacion,
efectos sobre las personas y las tecnicas de atenuacion como
complemento de los ruidos aereos.
