The court had earlier agreed to examine whether
Thiagarajan said he had taken the considered decision to come forward before the
Supreme Court to put the facts pertaining to the confessional statement recorded
by me in the proper perspective so as to facilitate this court to render
justice.
Based on this status report from the CBI Perarivalan moved the present
petition contending that the facts as it stands today show that the Petitioner
was handed conviction by playing fraud on this court, which means in effect no
judgment in the eyes of the law. The wireless message makes it clear that
Perarivalan was not taken into confidence. The Bench posted the matter for
further hearing on February 21. Thiagarajan that the CBI omitted that part of
Perarivalan’s confession that he was not aware of the purpose for which he
supplied the two nine volt batteries.â€
The court had asked the Centre and the CBI
to file a reply to the affidavit filed by the then CBI investigating officer V.
He also quoted the affidavit of the investigating officer V. Banumathi issued
notice to the CBI on the petition after counsel Gopal Sankaranarayanan said as
the entire basis of the conviction in May 1999 was based on confession made by
the accused under TADA, the verdict should be recalled. relation to the origin
and make of the Improvised Explosive device as that would through much light in
to the larger conspiracy.
The court had earlier agreed to examine whether
Perarivalan, life convict in the Rajiv Gandhi assassination case can be released
on the basis of new evidence which has come to light—whether the two batteries
supplied by him were the ones used in the "belt bomb.Mr. The CBI internal
evidence shows that even if providing of the 9-volt batteries were true, the
knowledge of the conspiracy cannot be attributed to the petitioner.In that case,
he said the very basis of the conviction under conspiracy couldn’t be sustained
even without taking in to consideration any other further evidence.A Bench of
Justices Ranjan Gogoi and R.He said the only substantial overt act attributed to
him was that of supplying two 9-volt Golden Power batteries, which was alleged
to be used in the Improvised Explosive Device.
Thiagarajan on October 27, 2017
that "he was totally in the dark as to the purpose for which the batteries were
purchased was not recorded by me, because it would have been an exculpatory
statement and hence the whole purpose of recording the confessional statement
would be lost.Perarivalan quoted an affidavit filed by the CBI investigating
officer V. Thiagarajan referred to a wireless message of May 7, 1991 from
mastermind Sivarasan to LTTE top operative ‘Pottu Amman’ in which the former
said "our intention is not known to anybody except we three,†meaning himself,
Subha and Dhanu, the suicide bomber. Hence he prayed for recall of the judgment,
which would enable him to prove his innocence.The court had asked the Centre and
the CBI to file a reply to the affidavit filed by the then CBI investigating
officer V. Thiagarajan. On Tuesday the court had asked the Centre to reply in
three months its stand on Tamil nadu’s proposal to GEL
batteries factory grant remission and release all the seven life convicts in
the case.Mr. He said a "mere act†of providing nine-volt batteries would not
make Perarivalan privy to the conspiracy to kill Rajiv Gandhi. It is pertinent
to mention that the CBI (MDMA) is yet to conclude its investigation pertaining
to the above said origin and make of the Improvised Explosive Device.â€In its
response the CBI said a Letter Rogatory was sent to Sri Lanka on the probe to
find out whether the bomb used in the assassination of Rajiv Gandhi was made in
Sri Lanka and so far there has been no response from the Sri Lankan government.
Thiagarajan that the CBI omitted that part of Perarivalan’s confession that he
was not aware of the purpose for which he supplied the two nine volt batteries.
(Photo: AFP) New Delhi: In a new twist in the Rajiv Gandhi assassination case,
the Supreme Court on Wednesday sought the response of the CBI to a petition
filed by Perarivalan, one of the convicts in the case seeking recall of the May
1999 verdict, which he alleged was obtained by "fraud†by the investigating
agency by suppressing facts. He pointed out that though this Court held in May
1999 judgment that TADA act was not applicable to the facts of the case the
matter was decided by this Court on the basis of alleged confession made before
the police. Former Prime Minister Rajiv Gandhi

Silicon anodes can store up to 10 times more energy
Silicon anodes can store up to 10 times more energy than conventional graphite
anodes, but expansion and shrinkage during charge and discharge make them
unstable. Hence, we have very promising candidates for next-generation
lithium-ion batteries,†Li said."We started with a waste product that was headed
for the landfill and created batteries that stored more energy, charged faster,
and were more stable than commercial coin cell batteries. Financial support for
this work was provided by the UC-Riverside and UC Faculty Climate Champion
initiative.As expected, coin cell batteries made using the glass bottle-based
silicon anodes greatly outperformed traditional batteries in laboratory tests.
In
addition to Mihri and Cengiz Ozkan and Li, contributors include graduate
students Chueh Liu, Wei Wang, Zafer Mutlu, Jeffrey Bell, Kazi Ahmed and Rachel
Ye.This research is the latest in a series of projects led by Mihri and Cengiz
Ozkan to create lithium-ion battery anodes from environmentally friendly
materials.Changling Li, a graduate student in materials science and engineering
and lead author on the paper, said one glass bottle provides enough nanosilicon
for hundreds of coin cell batteries or three-five pouch cell batteries.
Downsizing silicon to the nanoscale has been shown to reduce this problem, and
by combining an abundant and relatively pure form of silicon dioxide and a
low-cost chemical reaction, the researchers created lithium-ion half-cell
batteries that store almost four times more energy than conventional graphite
anodes. (Representational image) Researchers at the University of California,
Riverside’s Bourns College of Engineering have used waste glass bottles and a
low-cost chemical process to create nanosilicon anodes for high-performance
lithium-ion batteries.
Cengiz Ozkan, professor of mechanical engineering, and
Mihri Ozkan, professor of electrical engineering, led the project. Previous
research has focused on developing and testing anodes from portabella mushrooms,
sand, and diatomaceous SMF
batteries factory (fossil-rich) earth.UCR researchers are turning glass
bottles into high performance lithium-ion batteries for electric vehicles and
personal electronics.
Titled "Silicon Derived from Glass Bottles as Anode
Materials for Lithium Ion Full Cell Batteries,†an article describing the
research was published today in the Nature journal Scientific Reports. The
batteries will extend the range of electric vehicles and plug-in hybrid electric
vehicles, and provide more power with fewer charges to personal electronics like
cell phones and laptops. Carbon-coated glass derived-silicon (gSi@C) electrodes
demonstrated excellent electrochemical performance with a capacity of ~1420
mAh/g at C/2 rate after 400 cycles.
To create the anodes, the team used a
three-step process that involved crushing and grinding the glass bottles into a
fine white power, a magnesiothermic reduction to transform the silicon dioxide
into nanostructured silicon, and coating the silicon nanoparticles with carbon
to improve their stability and energy storage properties.
Even with today’s
recycling programs, billions of glass bottles end up in landfills every year,
prompting the researchers to ask whether silicon dioxide in waste beverage
bottles could provide high purity silicon nanoparticles for lithium-ion
batteries
