A team of scientists from CETIM CERMAT and the Laboratoire de Physique et de Mécanique Textiles (LPMT), both in Mulhouse, France, have been working on the active structure for the past few years. In a recent study published in Smart Materials and Structures, they present the material called CBCM (controlled behavior composite material), which can bend when heated.“The main advantage of the CBCM is that the entire structure is active, compared to classical actuators used in this kind of structures, such as shape memory alloys (SMA) or piezoelectric materials, so there is no problem of junction and connection between the actuator and the structure,” coauthor Gildas L’Hostis of LPMT told PhysOrg.com. “Moreover, the load that can carry the structure is much greater than the one carried by an SMA or piezoelectric material because the performances are not as limited by the rigidity of the composite structure. A third advantage is the simplicity of use – directly on DC current with a variator.”The CBCM consists of thin laminate plates, inside of which are highly conductive carbon yarns that are connected to a generator and serve as the internal heating source. When the power is turned on, the current circulates in the carbon yarns and the temperature rises in the plates. The increased temperature causes the plates to bend, and the deformation can be controlled by controlling the amount of current. The researchers experimented with two kinds of plates: “single effect” plates that can bend in one direction, and “double effect” plates that can bend in two directions. In the thin single effect plates, the temperature reached 57°C (135°F) and the structure deflected up to 15 mm. In the double effect plates (which consist of a conductive layer on one side and insulating layer on the other), the temperature reached 70°C (158°F) on the conductive side and 42°C (108°F) on the insulated side, and deflected up to 3.7 mm. While the single effect plates could deflect more, the double effect plates could lift a heavier load.The scientists also discussed incorporating a control system into the material. By adding temperature and strain sensors to the CBCM, such a system could detect variations in its background and then adapt to the new context. To demonstrate the new material, the researchers built a prototype of a 4-mm-thick retractable aerodynamic flap that could be used on cars for stabilization at high speeds. Unlike the existing flap, which has three joints and is moved with a jack, the smart material structure could move simply due to its thermomechanical properties.With its advantages over other actuators and moving components, the CBCM smart material could be useful for a variety of applications. However, more research is needed to overcome some difficulties, which the scientists highlighted in their study. For instance, future research could include testing the rigidity of the plates and minimizing local overheating, possibly with the use of carbon nanotubes. “The CBCM has already been used to manufacture an active binder for pipes,” said coauthor Karine Buet-Gautier of LPMT. “Today, some other active connectors are under study.”More information: Drobez, H.; L’Hostis, G.; Buet Gautier, K; Laurent, F.; and Durand, B. “A new active composite.” Smart Materials and Structures 18 (2009) 205020 (7pp).Copyright 2009 PhysOrg.com.

(PhysOrg.com) — Scientists have developed a new smart material that can bend under the influence of an internal heat source. The material could be used as an aerodynamic flap in cars, in order to stabilize the vehicles at high speeds. Because the entire structure actively bends, the material could have advantages over actuators that need to be externally fixed to a structure.

The Murchison meteorite, a carbonaceous chondrite, fell near Murchison in Victoria in Australia in 1969, and is thought to be extremely ancient, possibly even older than the Sun, at 4.65 billion years old. It probably passed through the primordial clouds in the early Solar System, where it would have collected organic compounds. It was retrieved soon after it landed, which meant there was minimal chance of contamination, and it has been studied by scientists hoping the meteorite would yield clues about the possible origins of life on Earth. Leader of the research team, Dr Philippe Schmitt-Kopplin, said the meteorite was like a kind of fossil, and when you try to understand it, you are essentially looking back in time. Dr Schmitt-Kopplin, from the Helmholtz Centre Munich, in Germany, said he was really excited and amazed at the complexity they found. The meteorite has been investigated many times before, but earlier studies used gas chromatography and mass spectrometry and looked for specific compounds such as amino acids. The current study is the first non-targeted examination of the meteorite, and used high resolution technology such as NMR and ultra-high resolution mass spectrometry. The analysis took a few milligrams of crushed rock from the meteorite’s core, and then extracted the organic compounds with solvents.Their approach is based on metabolomics, which Schmitt-Kopplin and his team uses to analyze metabolites in body fluids. The technique attempts to find as many metabolites as possible, and they used the same system on the meteorite. Specifically, the new technique is known as the Fourier transform ion cyclotron resonance/mass spectrometry (FTICR/MS), which enables the scientists to weigh ionized molecules with the accuracy of the mass of an electron.The resolution of the analysis and the number of signals found makes the study record-breaking. Previous investigations were all targeted and used older technologies, and so the diversity was never discovered before. The results of the analysis identified about 14,000 different molecules in the meteorite, which can be combined in millions of different organic compounds. Schmitt-Kopplin said their calculations and interpolation were “very conservative”. Their findings show the nascent Solar System probably had more molecular diversity than present-day Earth.The results of the study appear in the Proceedings of the National Academy of Sciences (PNAS) journal.

Its system is titled “DIVE into World Heritage 3D,” and it was demonstrated at Digital Content EXPO 2012. This system put five 3-D cameras to work to shoot, and the display was via five HD plasma panels. “Imaging technology is progressing every day,” Masaru Kojima, manager of Panasonic’s Content Planning Center, told his interviewer. “Today we’re using full high-definition, but in the future pixel counts are likely to grow, as well as the size of the displays themselves.” Panasonic wants to be the “leading edge,” he said, as those kinds of devices become available. The camera is designed for professional videographers who would be attracted to a more affordable and easier-to-use tool than they had in the past. The camera is promoted as an easier way to work than coping with larger-scale setups for capturing content on a professional level. The AG-3DA1 is equipped with dual lenses and two full 1920 x 1080 2.07 megapixel 3-MOS imagers.The camera can automatically recalibrate without the need for external equipment. There is immediate 3-D image capture. The camcorder incorporates stereoscopic adjustment controls; functions for automatically correcting horizontal and vertical displacement are provided, whereas conventional 3-D camera systems required these adjustments to be made by a PC or external video processor, said Panasonic. At less than six pounds, the AG-3DA1 is lighter weight and smaller in contrast to heavy 3-D rigs. Panasonic said the AG-3DA1 is able to perform in extreme environments and stands up better to temperature extremes, shock, and vibration. The company also noted that the camera uses standard, re-recordable SDHC/SD memory cards. © 2013 Phys.org This document is subject to copyright.

It sounds like science fiction to suggest that every cell in the human body is occupied by a tiny genome-equipped organelle, with which we exist in symbiosis. But in actuality, eukaryotic life is dependent on mitochondria, which provide energy to the cell in the form of adenosine triphosphate (ATP). Over millennia, the genomes of mitochondria evolved under selection for minimal gene content, but researchers have been unable to determine why some but not all mitochondrial genes have been transferred to the nuclear genome. An international collaborative of researchers formed an interesting hypothesis regarding this phenomenon: The mitochondrial genome encodes hydrophobic membrane proteins which, if encoded in the nucleus, would be filtered by the signal recognition particle (SRP) and misdirected into the endoplasmic reticulum. The researchers conducted a study exploring their hypothesis and have published their results in the Proceedings of the National Academy of Sciences. In order to predict if a protein would be targeted by SRP, the researchers calculated the free insertion energy of transmembrane proteins, which, if scored zero or less, were considered to be hydrophobic. Higher scores were rated marginally hydrophobic. If a transmembrane protein domain (TMD) scored hydrophobic and the length of its tail was longer than 120 amino acids, the researchers predicted it would be arrested by SRP and directed into the endoplasmic reticulum.They expressed such proteins in cellular cytoplasm and were able to determine that they were, in fact, arrested by the SRP and directed to the endoplasmic reticulum. Further, the researchers observed that the mistargeting of these hydrophobic proteins into the soluble medium of the endoplasmic reticulum resulted in the formation of aberrant honeycomb structures similar to those observed during viral infections. “We conclude that genes for hydrophobic membrane proteins of more than 120 amino acids are likely retained in distinct organelle genomes to ensure a correct localization of these proteins and avoid transport to the endoplasmic reticulum,” the authors write.Thus, the researchers conclude, the selection against mistargeting hydrophobic proteins into the endoplasmic reticulum posed at least one major selective constraint on the retention of the mitochondrial genome. They bolster this finding by comparing it to similar membrane dynamics in the chloroplasts of plants.Previous studies have suggested that one-third of mitochondrial proteins have evolved in response to the specific environmental constraints of different species. Most of these proteins are involved with transport, regulatory, and membrane functions. The results of the current study are consistent with these findings. A persistent mystery has been the evidence that in rare cases, transfers of otherwise universal mitochondrial genes into the nuclear genome have occurred. The results of the current study present an explanation: These particular proteins demonstrate reduced hydrophobicity in those species in which the transfer took place.Clinical applications include the development of methods to cure human mitochondrial genetic diseases, such as Leber’s hereditary optic neuropathy. “These results resolve the long-standing question about why aerobic mitochondria and photosynthetic chloroplasts need a distinct compartmental genome, by and large, although other factors may be involved,” the authors write.

The vesicles are calcium and phosphate rich, containing organic materials such as acidic proteins. In a new study now published in Science Advances, Tomoaki Iwayama and colleagues at the departments of periodontology, biomedical research, oral science, biomaterials and oral anatomy development used scanning electron-assisted dielectric microscopy (SE-ADM) and super-resolution microscopy (SRM) to assess live osteoblasts during conditions of mineralization at nano-level resolution. They found the calcium-containing vesicles to be multi-vesicular bodies containing mineralizing nanovesicles or matrix vesicles (MVs). According to the observations, the MVs could be transported together with lysosomes and secreted by exocytosis.

Credit: Science Advances, doi: 10.1126/sciadv.aax0672 To overcome these limitations in the present work, Iwayama et al. used a new microscopic system known as scanning electron-assisted dielectric microscopy (SE-ADM). The method had previously achieved nanoscale resolution and high-contrast imaging for mammalian cells in aqueous media without staining. The scientists used the same technique (high resolution SE-ADM) to explore the possibility of viewing MVs in intact osteoblasts to understand biogenesis of MV trafficking. For the osteoblast cell line they used murine (mouse) osteoblastic cell line KUSA-A1, with high osteogenic capacity in vitro and in vivo. After cell culture under adequate conditions, Iwayama et al. observed the cells with SE-ADM to identify normal intracellular structures. The scientists observed MVs to align with collagen fibrils after 4 to 10 days of cell growth in osteogenic media and the secreted particle size increased due to fusion or particle growth, with their sizes consistent with previous reports to suggest they were indeed MVs.

They cultured the cells in calcium-containing osteogenic media and stained them with LysoTracker to detect the intracellular components of interest. Iwayama et al. located the calcein-fulfilled vesicles matched with lysosomes to suggest the biogenesis of MVs within lysosomes after their fusion with calcein+ vesicles. The scientists followed the experiments with loss-of-function and functional inhibition studies to further deconstruct the pathways and examine intracellular mechanisms of action during live cell mineralization in vitro. Upon further examination with SE-ADM, they noted the involvement of the lysosomal pathway to transport and secrete intraluminal MVs in a similar process to exosomes. Interestingly, both exosomes and MVs are categorized as extracellular vesicles with similar sizes; they are both secreted by osteoblasts and have shared functions during cell-cell communication. Scientists had previously reported the involvement of mitochondria during mineralization due to the presence of electron-dense calcium and phosphorous-rich granules in osteoblast mitochondria. This was observed with a modified cryotechnique. Furthermore, reports also suggest the direct contact of lysosomes and mitochondria with functional significance. When Iwayama et al. stained cells with LysoTracker together with MitoTracker and observed the intracellular components under N-SIM structured illumination super-resolution microscopy (SRM). They observed the presence of most calcein-fulfilled vesicles next to mitochondria and matched with lysosomes. During SRM-time lapse imaging, the scientists further obtained views of intracellular transport of LysoTracker containing vesicles fused to static calcein vacuoles adjacent to mitochondria to validate their hypothesis. In this way, together with observations of other SRM systems and additional cell lines, Tomoaki Iwayama and colleagues proposed a mineralization mechanism. Wherein lysosomes played a central role in intracellular MV biogenesis and trafficking within osteoblasts. It was reasonable to involve lysosomes for osteoblasts to transport amorphous calcium phosphate without crystallization during its transport in the cytosol. The scientists aim to conduct further experiments to understand the regulatory molecules for MVs and investigate if MVs and exosomes have similar constitutions and mechanism underlying their generation, secretion and function. The SE-ADM strategy used in the present work can be installed into existing scanning electron microscopy apparatus at a low cost. The work developed in the study will offer non-invasive, high-resolution imaging at the nanoscale applicable to all scientific fields. In the next step, Iwayama et al. examined if these particles were MVs containing calcium and/or phosphate. For this, they cultured the cells in osteogenic media for 7 days and observed them using SE-ADM to record very smooth structures without crystal facets. This suggested that the MVs did not crystallize but remained amorphous as also recorded in a previous study. When the scientists examined the MVs on a SiN (silicon mononitride) film, they observed sharp peaks corresponding to phosphorous, calcium, carbon and oxygen elements. They confirmed the findings using Raman spectroscopy to show the presence of calcium phosphate within MVs. The scientists also investigated the effects of hypophosphatasia a medical condition encoded by the Alpl (alkaline phosphatase) gene, wherein osteoblasts do not undergo mineralization in vitro. For this, they edited the genome of osteoblast cells using the CRISPR-Cas9 genome editing technology to generate Alpl knockout osteoblast clones. When Iwayama et al. examined the knockout clones using high-resolution SE-ADM, they did not observe MVs, which was further confirmed using spectrometric analysis due to the absence of phosphorous and calcium peaks. © 2019 Science X Network , Science During the physiological process of bone mineralization, the deposition of calcium phosphate crystals occurs in the extracellular matrix as a fundamental process in all vertebrates. In 1967, biologists Clarke Anderson and Ermanno Bonucci, individually visualized mineral-related particles in the extracellular space using electron microscopy (EM). Scientists later recognized these particles as mineralizing nano-vesicles or matrix vesicles (MVs). During the past 50 years of EM studies on MVs, biologists have grappled to understand the mechanism of MV formation and secretion, which remains largely unknown. Clarifying the mineralizing process of live cells with EM is challenging since sample preparation for EM requires steps on both chemical fixation and alcoholic dehydration. The steps can induce artefacts and even dissolve or remove unstable mineral precursors leaving an organic scaffold known as a “crystal ghost”. While scientists had successfully used the process of EM using fixed and dehydrated tissue to view the structure of mineralized collagen fibrils in bone, to study mineral precursors, they must employ cryo-EM processes to avoid dehydration and facilitate costly, extremely fast cooling with small specimens.

Layer upon layer of paint is added, creating an incredible depth to the colours and imparting a rich feel to the works, which appear to have an almost luminescent quality to them. When asked about his work, the artist commented: “My main focus is on the endangered flora and fauna in our rainforests. In 2005, I visited a rainforest in Sri Lanka, which had become my muse for many of my shows. I could have shown the negative aspects of destruction, such as people and animals dying, but I try to create happy and positive paintings.”When: January 28 – 31Where: NSIC Grounds, Okhla Industrial Area, New DelhiTimings: 11 am to 7 pm
