Control of ZnO Crystal Morphology through Face Specific Adsorptionyoucard
Many of the potential applications of ZnO are dependent upon either its overall shape (e.g. piezoelectric devices or LEDs), or the relative ratio of the different ZnO faces (e.g. catalysis). These applications have stimulated renewed interest in controlling the aspect ratio of ZnO crystals during their growth. One promising way to control the aspect ratio of ZnO crystals during hydrothermal growth is via the introduction of small organic molecules. Whilst there have been many studies showing that particular molecules affect ZnO crystal shape, few studies explain exactly how particular molecules influence growth. The overriding goal of the work contained in this thesis is to enhance understanding of how small organic molecules affect ZnO growth surfaces.

Cancer cell metabolism: special Reference to Lactate PathwayAADYARAJPANDEY1
Normal Cell Metabolism:
Cellular respiration describes the series of steps that cells use to break down sugar and other chemicals to get the energy we need to function.
Energy is stored in the bonds of glucose and when glucose is broken down, much of that energy is released.
Cell utilize energy in the form of ATP.
The first step of respiration is called glycolysis. In a series of steps, glycolysis breaks glucose into two smaller molecules - a chemical called pyruvate. A small amount of ATP is formed during this process.
Most healthy cells continue the breakdown in a second process, called the Kreb's cycle. The Kreb's cycle allows cells to “burn” the pyruvates made in glycolysis to get more ATP.
The last step in the breakdown of glucose is called oxidative phosphorylation (Ox-Phos).
It takes place in specialized cell structures called mitochondria. This process produces a large amount of ATP. Importantly, cells need oxygen to complete oxidative phosphorylation.
If a cell completes only glycolysis, only 2 molecules of ATP are made per glucose. However, if the cell completes the entire respiration process (glycolysis - Kreb's - oxidative phosphorylation), about 36 molecules of ATP are created, giving it much more energy to use.
IN CANCER CELL:
Unlike healthy cells that "burn" the entire molecule of sugar to capture a large amount of energy as ATP, cancer cells are wasteful.
Cancer cells only partially break down sugar molecules. They overuse the first step of respiration, glycolysis. They frequently do not complete the second step, oxidative phosphorylation.
This results in only 2 molecules of ATP per each glucose molecule instead of the 36 or so ATPs healthy cells gain. As a result, cancer cells need to use a lot more sugar molecules to get enough energy to survive.

introduction to WARBERG PHENOMENA:
WARBURG EFFECT Usually, cancer cells are highly glycolytic (glucose addiction) and take up more glucose than do normal cells from outside.
Otto Heinrich Warburg (; 8 October 1883 – 1 August 1970) In 1931 was awarded the Nobel Prize in Physiology for his "discovery of the nature and mode of action of the respiratory enzyme.
WARNBURG EFFECT : cancer cells under aerobic (well-oxygenated) conditions to metabolize glucose to lactate (aerobic glycolysis) is known as the Warburg effect. Warburg made the observation that tumor slices consume glucose and secrete lactate at a higher rate than normal tissues.
THE IMPORTANCE OF MARTIAN ATMOSPHERE SAMPLE RETURN.Sérgio Sacani
The return of a sample of near-surface atmosphere from Mars would facilitate answers to several first-order science questions surrounding the formation and evolution of the planet. One of the important aspects of terrestrial planet formation in general is the role that primary atmospheres played in influencing the chemistry and structure of the planets and their antecedents. Studies of the martian atmosphere can be used to investigate the role of a primary atmosphere in its history. Atmosphere samples would also inform our understanding of the near-surface chemistry of the planet, and ultimately the prospects for life. High-precision isotopic analyses of constituent gases are needed to address these questions, requiring that the analyses are made on returned samples rather than in situ.
Nutraceutical market, scope and growth: Herbal drug technologyLokesh Patil
As consumer awareness of health and wellness rises, the nutraceutical market—which includes goods like functional meals, drinks, and dietary supplements that provide health advantages beyond basic nutrition—is growing significantly. As healthcare expenses rise, the population ages, and people want natural and preventative health solutions more and more, this industry is increasing quickly. Further driving market expansion are product formulation innovations and the use of cutting-edge technology for customized nutrition. With its worldwide reach, the nutraceutical industry is expected to keep growing and provide significant chances for research and investment in a number of categories, including vitamins, minerals, probiotics, and herbal supplements.

Dear ICS members,
It is my pleasure to announce that the winner of the 2017 ICS-Uri Golik Prize for an Excellent
Graduate Student is Ms. Elena Meirzadeh of the Department of Materials and Interfaces at
the Weizmann Institute of Science.
Elena Meirzadeh was born in Iran in 1989 and immigrated to Israel in 2000. She received her
B.Sc. in Chemistry from the Hebrew University of Jerusalem (2008-2011), started her M.Sc.
studies in the Weizmann Institute (2011) under the supervision of Profs. Igor Lubomirsky and
Meir Lahav, and later switched to a direct Ph.D. track. Her thesis topic is “The Beauty of
Imperfections – Studied in Molecular Crystals by Pyroelectricity”.
Ms. Elena Meirzadeh
Elena.Meirzadeh@weizmann.ac.il
Elena studies how defects and deviations from symmetry influence the macroscopic
properties of crystals. She uses electrical measurement techniques, such as pyroelectricity
and impedance spectroscopy, to improve fundamental understanding of crystal structure,
function and growth. Pyroelectricity is the ability of polar materials to develop surface charge
with temperature. By improving the current measurement techniques she increased the
sensitivity of this analytical method. Consequently, by detecting pyroelectricity from near
surface polar layers of centrosymmetric crystals she provided support for a non-classical
crystal growth mechanism. For example, she discovered that certain solvents, which are
used for growing crystals, are incorporated within the bulk of the crystals. These findings
shed light on how different solvents induce crystallization of metastable polymorphs.
Moreover, she was able to determine the structure of doped polar domains at the molecular
level, at concentrations as low as <0.5%, by combining pyroelectric measurements with
dispersion-corrected DFT, MD simulations and Neutron diffraction at different temperatures.
Elena has published her work in high profile journals, including Angew. Chem., PNAS, JACS,
Acc. Chem. Res., APL Materials, Ferroelectrics, and Nature Commuications. She was an
invited speaker at the 2017 Gordon Conference on Crystal Growth & Assembly, received the
Intel-IVS 2016 award, the Best Oral Contribution Award in the 2016 MRS meeting, the
Lodovico prize for the most dynamic student at the International School of Crystallography,
and the Otto Schwarz Memorial Graduate Scholarship.
This is the first time that the ICS-Uri Golik Prize is being awarded. The award ceremony will
take place during the first day of the 83
rd
ICS Annual Meeting on February 13, 2018.
Congratulations to Elena for her achievements!
