Counterclaim Defendant, Case No
UNITED STATES DISTRICT COURT EASTERN DISTRICT OF MISSOURI EASTERN DIVISION NESTLÉ PURINA PETCARE COMPANY, Plaintiff/ Counterclaim Defendant, Case No. 4:14-cv-859-RWS v. BLUE BUFFALO COMPANY LTD., Defendant/ Counterclaim Plaintiff. DECLARATION OF VINAYAK P. DRAVID, PH.D. I have been retained by Blue Buffalo Company Ltd. (“Blue Buffalo”) and have been asked to provide a preliminary opinion about the scientific adequacy and reliability of the conclusions set forth in the Expert Report of James V. Makowski dated July 23, 2014 (PUR_000207-52), (“Makowski Report”). In his Report, Dr. Makowski, purports to reach definitive quantitative conclusions about the compositions of various Blue Buffalo products based solely on visual observations of the products using rudimentary optical microscopy. Briefly, Dr. Makowski obtained various product samples directly from Nestlé Purina. Dr. Makowski then examined the processed samples under a low-power light microscope, with very limited capabilities. Dr. Makowski purported to identify ingredients based solely on a subjective, visual comparison of what he observed to “a reference library of known ingredients” – though his Report fails to identify the reference library and validate its utility. Dr. Makowski made no effort to document what features he saw that led to a particular identification (save for four low quality, scale-less photographs, three of which were from a single sample). In other words, he apparently made these identifications based on 7271442v.1 gut feeling. Similarly, Dr. Makowski purported to quantify the amount of ingredients he identified through a “visual estimate,” though his Report and supporting laboratory notebook fail to set forth any methodology for arriving at such numbers.

Researchers Demonstrate First Stable Semiconductor Neutron Detector 15 January 2020
Researchers demonstrate first stable semiconductor neutron detector 15 January 2020 arrays of crystals. The study will be published in the Jan. 16 issue of the journal Nature. "People have imagined semiconductor neutron detectors for a long time," said Northwestern's Mercouri Kanatzidis, who led the research. "The idea was there, but no one had the right material to do it." Kanatzidis is the Charles E. and Emma H. Morrison Professor of Chemistry in Northwestern's Weinberg College of Arts and Sciences. He has a joint appointment with Argonne. A prototype of a working, pocket-sized neutron detector made with a high lithium-containing material. Credit: Northwestern University/Argonne National Laboratory Homeland Security might soon have a new tool to add to its arsenal. Researchers at Northwestern University and Argonne National Laboratory have developed a new material that opens doors for a new class of neutron detectors. With the ability to sense smuggled nuclear New material (lithium-indium-phosphorous-selenium) is materials, highly efficient neutron detectors are lithium-rich, making the semiconductor neutron detector critical for national security. Currently, there are possible. Credit: Northwestern University/Argonne two classes of detectors which either use helium National Laboratory gas or flashes of light. These detectors are very large—sometimes the size of a wall. Northwestern and Argonne's material introduces a When heavy elements, such as uranium and third class: a semiconductor that can absorb plutonium, decay, their atoms eject neutrons from neutrons and generate electrical signals that can their nuclei. Most neutron detectors are so-called be easily measured. The semiconductor-based scintillators that work by sensing ejected neutrons detector is also highly efficient and stable.

In particular, the light emission of low-dimensional halides based on the 5s2 cations Sn2+ and Sb3+ has found utility in a variety of applications complementary to those of the three- dimensional halide perovskites because of its unusual properties such as broadband character and highly temperature-dependent lifetime. These properties derive from the exceptional chemistry of the 5s2 lone pair, but the terminology and explanations given for such emission vary widely, hampering efforts to build a cohesive understanding of these materials that would lead to the development of efficient optoelectronic devices. In this Perspective, we provide a structural overview of these materials with a focus on the dynamics driven by the stereoactivity of the 5s2 lone pair to identify the structural features that enable strong emission. We unite the different theoretical models that have been able to explain the success of these bright 5s2 emission centers into a cohesive framework, which is then applied to the array of compounds recently developed by our group and other researchers, demonstrating its utility and generating a holistic picture of the field from the point of view of a materials chemist.

Mercouri Kanatzidis Premio Energie Rinnovabili Energia Ricavata Dal Calore Disperso, Tramite L’Utilizzo Di Materiali Termoelettrici Nanostrutturati
ENI AWARD 2015 Renewable Energy Prize Professor Mercouri Kanatzidis Premio Energie Rinnovabili Energia ricavata dal calore disperso, tramite l’utilizzo di materiali termoelettrici nanostrutturati Il premio della sezione "Energie rinnovabili" e stato assegnato a Mercouri Kanatzidis, della Northwestern University di Evanston (Illinois, USA), uno dei leader internazionali della chimica inorganica e dello stato solido. La sua ricerca concerne lo sviluppo di nuovi semiconduttori allo stato solido capaci di recuperare il calore disperso e convertirlo direttamente in energia elettrica. Piu precisamente la novita risiede nell’aver "nanostrutturato" il materiale di questi semiconduttori termoelettrici, ovvero l’avervi aggiunto nanocristalli con determinate composizioni i quali, ad alte temperature, portano ad un incremento significativo delle prestazioni. In pratica e stato infranto il record, che resisteva da 40 anni, di efficienza nella conversione calore-elettricita e si sono fornite le basi di conoscenza per ulteriori sviluppi, fra cui la realizzazione di veri e propri generatori termoelettrici. E stato stimato che le tecnologie sviluppabili a valle del lavoro del prof. Kanatzidis potrebbero consentire il recupero di almeno 50 GW su scala globale. Biografia Mercouri G. Kanatzidis e nato a Thessaloniki, in Grecia, nel 1957. Laureatosi presso l’Aristotle University, in Grecia, ha conseguito il dottorato in Chimica presso la University of Iowa nel 1984. Ha servito in qualita di postdoctoral fellow presso la University of Michigan e la Northwestern University dal 1985 al 1987. Attualmente ricopre l’incarico di Charles E. and Emma H. Morrison Professor in Chimica, presso la Northwestern University. Il professor Kanatzidis e stato nominato Presidential Young Investigator da parte della National Science Foundation, Alfred P.

Prof. Mercouri G. Kanatzidis
Amazing 3D and 2D Halide Perovskites: All the Things They Do Mercouri G. Kanatzidis Department of Chemistry, Northwestern University, Email: [email protected], Web: http://www.chemistry.northwestern.edu/people/ core-faculty/profiles/mercouri-kanatzidis.html Abstract Three-(3D) and two-dimensional (2D) layered halide perovskites are highly promising semiconductors for optoelectronic applications ranging from solar cells, light emitting diodes, soft radiation detector, hard radiation detectors, etc. The 3D versions of these compounds adopt the three-dimensional ABX3 perovskite structure, which consists of a network of corner-sharing BX6 octahedra, where the B atom is a divalent metal cation (typically Ge2+, Sn2+ or Pb2+) and X is a monovalent anion (typically Cl−, Br−, I−); the A cation is selected to balance the total charge and it can be a Cs+ or a small molecular species. Another class of materials gaining significance are the two-dimensional (2D) perovskites -a blend of perovskites with layered crystal structure- (Ruddlesden-Popper type) offer a greater synthetic versatility and allow for more specialized device implementation due to the directional nature of the crystal structure. A remarkable advantage of the 2D perovskites is the readily tunable functionality by incorporating a wide array of organic cations into the 2D framework and by controlling the slab thickness, in contrast to the 3D analogues which have limited scope for structural engineering. We present the new homologous series, (C(NH2)3)(CH3NH3)nPbnI3n+1 (n = 1, 2, 3), of layered 2D perovskites which is different from Ruddlesden-Popper type. Short Biography Mercouri G. Kanatzidis received his B.S. in chemistry from Aristotle University, Thessaloniki, Greece, in 1979 and his Ph.D.
