Bio-Molecular Engineering is the Future of Molecular BiologyBob Eisenberg
Bio-Molecular Engineering is the Future of Molecular Biology: Now that we have large numbers of excellent structures, we molecular biologists must turn to studying how they work. That is the task of BioMolecular Engineering that uses almost the same tools as classical membrane biophysics. Both treat systems as devices, with inputs, outputs and power supplies, that ONLY function with flow, away from equilibrium.

A 1,3-dipolar cycloaddition is a fascinating and diverse reaction that can be used in stepwise syntheses of large molecules, such as masked aldol reactions, and has potential biological applications. While it is an incredibly useful reactions, is also has a simple mechanism.

Advances in Organic Chemistry in Academia Using Real-Time In Situ Mid-FTIR - ...pscholl
Three case studies from scientific literature that illustrate how real-time in situ mid-FTIR (ReactIR) is used to advance the understanding of chemical reactions.

A kinetic study is reported for the homologation of methanol to give ethanol. Cobalt carbonyl and iodine or cobalt iodide were used as catalyst systems with tri-n-butylphosphine as ligand. The reaction was investigated in 1,4-dioxane in a batch unit at (CO + H2) pressures between 3 and 15 MPa, with H2/CO ratios in the range of 0.33
to 3. The temperature was varied over the range of 150 to 210°C. The reaction rate was found to be first order with respect to methanol and cobalt concentrations and CO partial pressure. A rate expression is derived. A reaction mechanism is proposed in which the rate-determining step is suggested to be the reaction of methanol with a CO-rich cobalt complex existing in low concentration with regard to cobalt used.
Saturation of ions in channels and solutions a Fermi-Poisson treatment 11-23-...Bob Eisenberg
Ions in water, and in and near channels, proteins, nucleic acids, and electrodes are difficult to analyze, because everything interacts with everything else through the electric field and through the steric exclusion of ions and water. Ions and water have their own space and cannot overlap significantly. Excluded volume has almost always been treated by enforcing force laws that prevent overlap. Such treatments are difficult to compute because of the singularity of the forces and the need for three dimensions. Here we take a different approach and enforce a Fermi like distribution of the entropy of mixtures of spheres of any size, derived by J.-L. Liu. We show that this approach fits the complex properties of calcium channels, and the properties of gramicdin channels, computed from their full three dimensional structure. Using the simplest shell treatment of hydration, we successfully compute the activity (free energy per mole) curves of pure calcium and sodium chloride solutions. The Fermi-Poisson approach uses the full consistency of its mathematics to replace the computation of repulsive forces. It may prove to be good enough to detail with experimental data in three dimensions difficult to deal with accurately in any other way.

DIÁLOGOS ENTRE OS SABERES DA PRÁTICA E A TEORIA: O QUE DIZEM OS (AS) ACADÊMIC...ProfessorPrincipiante
As pesquisas sobre o conhecimento que os docentes constroem em sua ação têm sido
alvo de muitos estudos, pois segundo Shön, (2000) o conhecimento profissional pode se
construir na prática, no momento em que os professores (as) “pensam enquanto fazem”.
Essa capacidade de agir na prática é denominada pelo autor como um processo de
reflexão-na-ação, pois nem todas as situações que se tecem nesses contextos estão
transcritas em algum manual técnico. Muitas vezes para encontrar saídas para diversos
problemas de forma competente, o professor pode improvisar, inventar e testar
estratégias situacionais que ele próprio produz.
Zeichner (1995) considera duas categorias que devem ser levadas em conta no estudo
da prática dos professores (as). Uma é a reflexão-na-ação, que se refere aos processos
de pensamento que se realizam na ação, sempre que os professores (as) têm
necessidade de reenquadrar uma situação problemática tomando como base a
informação obtida a partir da ação, desenvolvendo experiências para conseguir as
respostas mais adequadas. A outra é a reflexão-sobre-a-ação que se refere ao processo
de pensamento que ocorre retrospectivamente sobre uma situação problemática e sobre
as reflexões-na-ação produzidas pelo (a) professor (a).
Nesse sentido, acreditamos que o referencial trazido por esses autores possibilita a
criação de instrumentos teóricos capazes de compreender a complexidade dos
fenômenos e ações que se desenvolvem durante as atividades práticas. Monteiro (2001)
alerta para a crítica à racionalidade técnica, a qual tem gerado várias pesquisas que
procuram superar a relação linear e mecânica entre conhecimento técnico científico e a
prática da sala de aula.
AÇÕES CARACTERÍSITCAS DO TRABALHO ESCOLAR: CONDICIONANTES PARA A ORGANIZAÇÃO ...ProfessorPrincipiante
A cultura escolar, suas formas de organização e funcionamento, é uma preocupação constante em nossos estudos e pesquisas, sobretudo porque identificamos nesses contextos condicionantes e/ou prescrições com forte influência sobre o trabalho docente. Essa preocupação não é exclusividade nossa, nos acompanham nessa questão autores como Canário (1995), Barroso (1996) Rockwell (1995) que tomam a instituição escolar como objeto de estudo, a fim de compreender processos mais ampla e que se encerram no trabalho docente
Photocatalysis has now become an emerging scientific discipline due to its interdisciplinary nature. The wide range of research groups is now working on different aspects of photocatalysis worldwide. It is one of the technology the world looking forward to address environmental as well as energy related issues. Hence we can call it as a technology for the future or a dream technology! We need to overcome too many hurdles to implement this technology in real life. Like any other discipline there is a lot of misunderstanding/ misconceptions in photocatalysis.
Most frequently cited article in the field of photocatalysis is by Fujishima and Honda published in 1972 in nature and it has been cited by the photocatalytic community as an origin of photocatalysis. This aspect is not true at all. This article cannot be the origin of photocatalysis. This article only promoted photocatalytic studies. The author itself, actually, started a research career in the “boom” of photocatalytic studies initiated by this article.
This small presentation aims to deliver some misconceptions like above in photocatalysis. The entire presentation is based on different personal commentaries written by Jean Mary Hermann and Bunsho Ohtani. Some recent articles relevant to the topic are collected by the speaker itself and put it in one platform.

Synthesis and characterization of a novel TAML activator with significant steric hindrance.
Synthesized a new TAML activator and proved by kinetic analysis that oxidation of the
aromatic moiety of TAML ligands is not a significant contributor to catalyst inactivation.
Established through kinetic and product analysis the mechanism of formation of high-
valent oxidation states under a variety of conditions, including the formation of a
previously unreported Fe(V)-oxo species in water.
Discovered evidence for a proton-coupled electron transfer process through
electrochemical studies in water, which were not possible with previous catalysts.
2. Kinetics and environmental and biological impacts of TAML-catalyzed degradation of
micropollutants with hydrogen peroxide and hypochlorite.
Measuring the kinetics of the oxidation of a series of substrates with TAML activators
and compiling data toward developing a structure-activity relationship for substrates.
Analyzing products of reactions to determine whether TAML catalysts can shift the
mechanism of substrate reactivity with hypochlorite from chlorination to oxidation.
Catalyzed oxidative degradation of ethinyl estradiol with TAML activators and hydrogen
peroxide in water over a wide range of conditions.
Demonstrated that TAML/peroxide treatment is effective for remediation of ethinyl
estradiol in water by kinetic and biological assays.
Measured the rate constant of degradation under environmentally relevant conditions.
Characterized several intermediate products, several of which were novel.
Collaborated with Prof. Susan Jobling at Brunel University in England to show that
estrogenicity of the reaction mixture was greatly reduced after treatment.
Mentored nine undergraduate students in support of the projects above.
