ова хемпкритот навистина ветува, прашање е само дали ќе се дозволи доволно индстриски да се одгледува конопот, а кој има и ред други индустриски предности [1]

...
My research is showing that Hempcrete only has a lower compression rate, and over a year or two, becomes stronger than concrete, while also being a better insulator, as was said, and more flexible. Also, weathering isn't as crucial compared to concrete. People need to look outside the box, modern building materials are too expensive and not as efficient

HEMPKRIT - BETON OD KONOPLJE

On: 23/07/2014 By: admin Posted in zelena gradnja 0
Inovativno rešenje za rastući problem održivosti građevinskih materijala je hempkrit (hempcrete iliti beton od konoplje)– mešavina krečnjaka, peska i konoplje (one obične). Prema Američkom Savetu zelene gradnje, zgrade su odgovorne za 38% od svih emisija CO2 u Americi. Jedna od velikih koristi hempkrita je ta da konoplja apsorbuje CO2 i stvara kiseonik za vreme svog rasta.

Sam materijal je bio-kompozitan i pravi se od srži konoplje pomešane sa vezivnim materijalom čija je osnova kreč. Najveća mana hempkrita je to što je njena gustina samo 15% od tradicionalnog betona , što znači da hempkrit mora da se koristi u kombinaciji sa okvirom od drugog materijala koji može da podnese vertikalno opterećenje građevine. S druge strane, hempkrit ima veoma visoku otpornost na plamen u odnosu na ostale građevinske materijale.

Beton od konoplje ima veliki broj namena – od građenja zidova, preko podova do izolacije krovova. Materijal je otporan na vatru, vodu, dobar je izolator, ne truli kad se koristi iznad zemlje i može u potpunosti da se reciklira. Sav šut koji ostane posle rušenja zgrade od hempkrita može da se iskoristi kao đubrivo. Takođe, ovaj materijal „diše“, pa nema buđi i problema sa vlagom. To znači da se koristi i manje energije nakon gradnje za hlađenje i zagrevanje prostora, jer toplotna izolacija betona od konoplje drži temperaturu konstatnom.

    Silipint touts it uses “100% food-grade” silicone. When shaped into a glass, the result is an insulating vessel that works with a range of liquids.
    ...
    The company notes its cups can withstand temperatures up to 500 degrees F.
    ...
    They are dishwasher-safe. But a simple rinse-out and air dry is all that’s needed after grabbing a glass of water. Silicone does not support microbiological growth.

    Because of their versatility, the cups are convenient for travel or camping. They flex and stack together, and the cups are unbreakable.

    Silipints come in 8- and 16-ounce sizes and cost about $8

    во овој контекст може и стаклото да куртули од еколошкиот кабает по природата [1

    Metals Absorb Light, Repel Water after Laser Conditioning

    ROCHESTER, N.Y., Jan. 20, 2015 — A new laser micropatterning technique turns normally shiny metals black and makes them so hydrophobic that water droplets bounce off.

    University of Rochester researchers carved microgrooves into sheets of platinum, titanium and brass using an 800-nm laser firing 65-fs pulses. Nanostructures spontaneously form on top of the grooves, giving the metals high optical absorption properties, as well as superhydrophobicity.

    "The material is so strongly water-repellent, the water actually gets bounced off. Then it lands on the surface again, gets bounced off again, and then it will just roll off from the surface," said professor Dr. Chunlei Guo.

    Most commercial hydrophobic and high-optical-absorption materials rely on chemical coatings that can degrade and peel off over time, Guo said. But laser-induced nano- and microstructures should not deteriorate, he said.

    "Many people think of Teflon as a hydrophobic surface, but if you want to get rid of water from a Teflon surface, you will have to tilt the surface to nearly 70 degrees before the water can slide off," Guo said. "Our surface has a much stronger hydrophobicity and requires only a couple of degrees of tilt for water to slide off."

    Guo and colleagues previously used laser surface conditioning to create superhydrophilic silicon, which absorbs water.

    A femtosecond laser was used to create detailed hierarchical structures on a platinum surface, as shown in this scanning electron microscope image. Courtesy of the Guo Lab/University of Rochester.

    The new batch of superhydrophobic surfaces could enable devices that resist rust and shed ice, dust and other contaminants. The principle could even be applied to make rain collectors and self-cleaning latrines in area where water is scarce.

    Meanwhile, the patterned metals’ light-absorbing properties could enhance sensors as much as solar cells.

    None of this will be possible, however, until the technology can be scaled up. It currently takes an hour to pattern a 1 × 1-in. metal sample.

    Funding came from the Bill & Melinda Gates Foundation and the U.S. Air Force Office of Scientific Research.

    The research was published in the Journal of Applied Physics (doi: 10.1063/1.4905616 [open access]).

    Peptides do windows
    Nobody really likes washing windows. And dirt and grime – the kind you find on windows – are the bane of a solar panel’s existence. The good news is that a group of researchers at Tel Aviv University in Israel, which set out originally to find a cure for Alzheimer’s disease, may have found a self-cleaning coating that will make window washing a thing of the past.

    Led by Ehud Gazit, a professor in the department of molecular micro-biology and biotechnology, the team discovered a way of controlling atoms and molecules of peptides to make them grow into what look like tiny blades of grass or “nanotubules.” The blades are about 100 nm in size – much smaller than a particle of dust. When the nanotubules group together, they form tiny, water-repellent forests. Because the nanotubules were created in a vacuum under high temperatures, the researchers knowthat they can withstand extreme heat.

    They see the water-repellent material as a potential coating for skyscraper windows and solar panels. Any dirt or dust that accumulated on the surface would be washed off by rain-water. According to doctoral candidate Lihi Adler-Abramovich, this research also has implications for electric cars. The nanotech material exhibits the property of a high-energy density capacitor, which can give a boost to electric batteries.

    2. и со антимикробиални својства
    ...

    Antimicrobial Peptides (AMPs) have gained a lot of attention because they are much less susceptible to development of microbial resistance. Other antibiotics may be susceptible to bacterial resistance, like multi-resistant staphylococcus aureus (MRSA) which is known as a common relic in the healthcare industry while other bacterial strains have become more of a concern for waste water treatment in local rivers or bays. AMPs can be functionalized onto a surface by either chemical or physical attachment. AMPs can be physically attached by using oppositely charged polymeric layers and sandwiching the polypeptide between them. This may be repeated to achieve multiple layers of AMPs for the recurring antibacterial activity. There are, however, a few drawbacks to this mechanism. Assembly thickness and polymer-peptide interactions can affect the diffusion of peptide to bacterial contact. Further research should be carried out to determine the effectiveness of the adsorption technique. However, they chemical attachment of AMPs is also widely studied.

    AMPs can be covalently bound to a surface, which minimizes the "leaching effect" of peptides. The peptide is typically attached by a very exergonic chemical reaction, thus forming a very stable antimicrobial surface. The surface can be functionalized first with a polymer resin such as polyethylene glycol (PEG).

    антибактерискиот момент е битен, но уште побитни се ен.еф. својства на материјалите, претпоставувам ко што може хидрогел да смести меѓу два стаклени панела би можело и меѓу пластика и меѓу алуминиум, та зошто не и најлон

    за сега кај паметните прозори не само што се добива можност за матирање односно приватност, туку и ен.еф. слој кој за разлика од low-e стаклото ќе ја спречуваат топлината рефлексно наместо константно, што отвора можност да може се додаде опција и за нивно активирање по потреба и без да бидат побудени топлински, односно ко кај интелигентните-фолиите да се регулира електрично [1] што во овој случај би требало да се направи со некое грејно тело односно жица

    како појава ова ќе биде идеален рурален новитет иако со фотовотаилчни стартери паметните прозори може да се насадат и сред дивина односно места без струја

    ‘Smart’ Windows Block Heat, Not Light

    SHANGHAI — A new kind of smart window blocks out heat when the outside temperature rises, potentially reducing the use of air conditioning. 

    Developed by researchers from several Chinese institutions, the windows turn an opaque white in response to external heat; this prevents heat from entering while still allowing light through. The windows become transparent again as temperatures drop.

    Current methods for making smart windows use jelly-like materials called hydrogels that swell in the heat, which hurts performance.

    The new smart windows incorporate microscopic hydrogel beads suspended in water and alcohol. Sandwiched between two panes of glass, the solution exhibited less swelling than its predecessors.

    The researchers built a model house using the smart windows, and tested their thermosensitive behavior and solar modulation ability using differential scanning calorimetery, UV-VIS-NIR spectrophotometery, dynamic light scattering and rheology.

    Research funding came from the National Natural Science Foundation of China, Fundamental Research Funds for the Central Universities, the Higher School Specialized Research Fund and a 111 Project grant.

     The work was published in Industrial & Engineering Chemistry Research (doi: 10.1021/ie502828b)

    единствен новитет апропо стаклениве муабети што наскоро може да изненади би бил флексибилни стакла, и иако има веќе слични пвц комбинации [1] истите треба да дотераат до еластичност налик органска мембрана

    во овој контекст сега има полимери кои ги промовираат како идеално решение за амбалажа, и нормално детски играчки налик прозирен пластелин, ова последново ветува али сепак е далеку од употреблива градежна иновација

    ... The new thin film is easily dispersed by spraying, spin-coating or painting it onto almost any surface, creating a film of consistent thickness between 50 and 200 nm. As such, Tour’s group recently confirmed that the graphene nanoribbon coating also would work on glass, where it performs much like tinted glass, except that it can prevent vehicle windows or buildings from icing up.

    Rice University Researchers Use Graphene as a De-Icing Agent for Glass

    Graphene has elicited reactions from the public that span from sheer wonder to puzzlement, as reports of the new, conductive and incredibly strong, single-atom-thick, transparent nanomaterial continue to draw attention. Still, everyday product applications have been relatively slow to develop.

    A recent finding by researchers at Rice University could change that. The group proposes using the carbon-based graphene as a de-icing agent for glass. The film is composed of graphene nanoribbons embedded in a polyurethane coating that can be painted and sprayed onto glazing in 50- to 200-nanometer-thick layers. And the material is transparent, maintaining clear views to the outdoors, while being a good conductor of electricity and heat.



    Originally conceived for and tested on military radar domes, the film gives windows the ability to reduce or eliminate the buildup of ice and the presence of fog. Unlike existing metal oxide–based coatings, the nanoribbon film is transparent to radio frequencies, allowing telecommunications signals to pass through. The film requires an electric current to function, however, which is something design teams will need to consider in terms of energy consumption and building systems integration.

    “[The capability is] going to be important, as Wi-Fi becomes more ubiquitous, especially in cities,” said James Tour, a materials science and nanoengineering professor at Rice, in a press release. “Signals can’t get through anything that’s metallic in nature, but these layers are so thin they won’t have any trouble penetrating.” He added that the nanoribbons could one day allow scientists to embed transparent electronic circuits in glass. Tour is a co-author of the related paper published this month by the Journal of Applied Materials and Interfaces.

    The coating has the potential to maintain transparency for building occupants in noticeable and unnoticeable manners, through both the passage of light and, of increasing importance, communications signals.

    Градежен скандал со магнезитни плочи ја тресе Европа!

    Судот во Данска донесе забрана за употреба на магнезитните градежни плочи, откако штетите достигнаа 100 милиони евра. Во Македонија и натаму се продаваат магнезитни градежни плочи, кои се вградуваат и во најголемите проекти.
    Станува збор за т.н. лесни градежни плочи увезени од Кина, рекламирани како евтина зелена алтернатива на квалитетните градежни сувомонтажни плочи, водоотпорни, отпорни на мувла и на удар. Се нудат како трајни и евтини решенија за заштита од ветер, ниски температури и бука.

    Проблемот доаѓа поради катастрофалното својство на плочите, кои иако треба да бидат водоотпорни, впиваат влага и по целосното заситување лачат на раствор од магнезитни соли, кои ја нагризуваат конструкцијата што ги носи.
    По откривањето на скандалот со магнезитните плочи кај соседите, шведската „Асоцијација на сопственици на домови“ плати истражување водено од Олоф Мундт-Петерсен, коешто покажа дека од 2009 година, само еден увозник продал повеќе од 10 до 15 илјади квадрати од магнезитните плочи.
    Во Данска овие плочи се на пазарот од 2010 година и просечно биле вградувани по 100 илјади м² месечно.
    „Плочите, при допир со влага, стануваат леплива маса слична на желатин, која ја губи целата носивост“, вели Мундт-Петерсен. Магнезиум хлоридот што излегува од влажните плочи ја нагризува конструкцијата и врзивните штрафови и затоа не смеат да се користат на позиции каде што има влага.

    По судската забрана во Данска покренати се стотици судски спорови, кои државата ги решава групно и ги обесштетува преку осигурителните компании кои биле ангажирани на објектите.
    За овој скандал прв се огласи еминентниот дански магазин Ingeniøren, по многуте тужби од семејствата против инвеститорите на објектите во кои живеат. Во нивните станови се појавила мувла, за првпат забележена во пролетта 2014. Сопствениците на преку 20.000 станови побарале отштета.
    За недостатоците на овие плочи во 2010-та извести и водечкиот градежен магазин во Шведска, Byggindustrin, по испитувањето на Техничкиот универзитет во Лунд, коешто ги покажа катастрофалните својства на панелите на тестовите во влажни услови.
    Врз база на сите овие испитувања и нивните заклучоци, магнезитните плочи го изгубија „Лебедовиот печат“, којшто на скандинавските пазари го добиваат материјалите со докажан квалитет.
    „Не се сеќавам на поголем скандал од овој. Без сомнеж ќе има големи последици за објектите во кои се вградени овие плочи. Корозијата може да сруши и цел објект“, вели претседателот на данската Инженерска асоцијација, Хенрик Гарвер.

    ова со глинава ветува, но оризовата арпа како еко-цигла иако креативен сепак е пропартизански момент ... хм швеѓаниве се надежни нема што, бар се реални додека 'останатите' фантазираат за револуционерни преврати и по индустријата и по менталитетот, а за тоа немаат нит подршка нит простор

    31.03.2016 - Translucent Wood? New material could replace glass in solar cells and buildings

    Lars Berglund, a professor at Wallenberg Wood Science Center at KTH - Stockholm'с Royal Institute of Technology, says that while optically transparent wood has been developed for microscopic samples in the study of wood anatomy, the KTH project introduces a way to use the material on a large scale. The finding was published in the American Chemical Society journal, Biomacromolecules.

    "Transparent wood is a good material for solar cells, since it's a low-cost, readily available and renewable resource," Berglund says. "This becomes particularly important in covering large surfaces with solar cells."

    Berglund says transparent wood panels can also be used for windows, and semitransparent facades, when the idea is to let light in but maintain privacy.

    The optically transparent wood is a type of wood veneer in which the lignin, a component of the cell walls, is removed chemically.

    "When the lignin is removed, the wood becomes beautifully white. But because wood isn't not naturally transparent, we achieve that effect with some nanoscale tailoring," he says.

    The white porous veneer substrate is impregnated with a transparent polymer and the optical properties of the two are then matched, he says.

    "No one has previously considered the possibility of creating larger transparent structures for use as solar cells and in buildings," he says

    Among the work to be done next is enhancing the transparency of the material and scaling up the manufacturing process, Berglund says.

    "We also intend to work further with different types of wood," he adds.

    "Wood is by far the most used bio-based material in buildings. It's attractive that the material comes from renewable sources. It also offers excellent mechanical properties, including strength, toughness, low density and low thermal conductivity."

    The project is financed by the Knut and Alice Wallenberg Foundation.

    Smart Window Coating That Controls Light and Heat Transmission Independently

    In an era when both environmental comfort and sustainability are key concerns in architecture, the tendency to cover buildings entirely in glass is among the most criticized and controversial traits of contemporary architecture, as all-glass buildings often guzzle energy thanks to their demanding cooling and heating requirements. Over the years, a number of fixes for this problem have been attempted, including smart glass solutions that allow users to modify the transparency of the window. The problem with this solution, however, is that smart glass is unable to block infrared (heat) transmission without ruining the very thing that makes glass attractive in the first place: its transparency to visible light.



    That conundrum may soon be a thing of the past, though. As reported by Phys.org, a team of researchers at the Cockrell School of Engineering at The University of Texas at Austin have developed a new smart window technology that allows users to selectively control the transmission of light and heat to suit their requirements.

    Led by chemical engineering professor Delia Milliron, the team from the Cockrell School of Engineering have created a new nanocomposite material which changes its properties with the application of a very small voltage - just as with regular smartglass. However, by using doped titania nanocrystals, their material can block near-infrared and visible light independently with small changes in the voltage applied.

    This development means that windows could be transparent to visible light while blocking up to 90% of infrared rays, keeping buildings cool on hot sunny days, or transparent to both to encourage solar heating on a cooler day. The material even has what the research team call a "warm" mode, which allows solar heating while reducing visible light transmission - useful, they say, for blocking the glare reflected off of snow without eliminating the solar gain required on a cold winter's day. Furthermore, these changes can be enacted in just a few minutes.

    "These two advancements show that sophisticated dynamic control of sunlight is possible," explained Milliron to Phys.org. "We believe our deliberately crafted nanocrystal-based materials could meet the performance and cost targets needed to progress toward commercialization of smart windows."

    Каков материјал е делот од фасадите што ги прават сега да изгледаат како дрво. 100% не е дрво. Мора да постои некоја техника да изгледа како да се даски.
