#Plastic parts for internal combustion engines Efforts to produce lighter vehicles necessarily include engine parts, such as the cylinder casing,
Fraunhofer ICT It self-evident that cars must become lighter in order to reduce fuel consumption. For most car designers this principally means body parts
but the powertrain system, which includes the engine, also accounts for a large proportion of the vehicle weight.
Until now, carmakers have relied on aluminum to reduce the weight of engine components such as the cylinder block.
In the future, car manufacturers will be able to achieve further weight savings by designing cylinder blocks in which certain parts are made of fiber-reinforced plastics.
An experimental engine developed by the Fraunhofer project group for new drive systems (NAS), which forms part of the Fraunhofer Institute for Chemical Technology ICT, in collaboration with SBHPP, the high-performance plastics business unit of Sumitomo Bakelite Co. Ltd.,

which the piston moves up and down millions of times during the life of the vehicle. The researchers also modified the geometry of these parts to ensure that the plastic is exposed to as little heat as possible.

and genetic materials and serve as a vehicle for communication between cells. In the nervous system, exosomes guide the direction of nerve growth,
have been refining cell-surface sensors known as chimeric antigen receptors, or CARS. Once inserted into T cells,
CARS prompt these cells to home in on particular proteins found primarily in tumors, where they launch a series of cancer-killing immune responses.
Dangers of CAR T cell Therapy CAR-equipped T cells have proven to be remarkably successful in the treatment of various forms of chemotherapy-resistant leukemia
But CAR T cell therapy can cause side effects so serious that they may require monitoring in an Intensive care unit several patients have died after receiving CAR T cells
while theye in the body. ome scientists have grappled with these problems by developing uicide switchesthat kill off CAR T cells
creating a new type of CAR T cell that is ffby default. Like CONVENTIONAL CAR T cells, these newly developed T cells will navigate toward
and interact with cancer cells, but will not launch any immune assault unless a specially designed drug has been administered.
This controller drug forms a chemical bridge between components inside the CAR T cells flipping the cells into an active, nstatus.
and selectively eliminated by the Lim group new CAR T cells, but only after the controller drug had been administered.
and colleagues does more than merely switch CAR T cells between nand ffstates. It can also act like a rheostat:
These combined control capabilities could be employed to manage the various side effects of CAR T therapy.
For CAR T cell treatments, T cells are removed from a patient blood, genetically engineered to carry CARS that target the patient tumor,
then reinserted into the bloodstream to exert their effects. Once inside the body, in addition to attacking tumors directly, CAR T cells, like all T cells, release signaling molecules called cytokines, some
of which recruit additional T cells to fight the tumor. Sometimes normal cells express small amounts of a cancer-associated protein targeted by a CAR T cell.
Because CAR T cells placed in the bloodstream pass immediately through the heart and lungs, these tissues can be damaged before the CAR T cells reach their intended target elsewhere in the body.
The control offered by the Lim laboratory new cells would allow physicians to leave CAR T cells inactivated until the heart
and lungs are less vulnerable to these irst passside effects. Even when CAR T cells attack only their correct target cancer cells,
side effects can still occur. In tumor lysis syndrome, the body is overwhelmed by toxic substances released when many tumor cells die in rapid succession.
Another side effect, known as a ytokine storm is a life-threatening vicious cycle in which released cytokines summon numerous T cells to the tumor,
but he believes that the research provides the foundation for practical remote control of CAR T cells on the near horizon.
In addition to drug control of CAR T nswitches, members of his laboratory are exploring other techniques to accomplish this goal,
such as controlling CAR T cell activation with light. While successful against blood cancers such as leukemia, CAR T cells have shown so far less efficacy against solid tumors that effect the colon, breast, prostrate, brain and other tissues.
The remote control strategy developed by Lim group may permit researchers to develop more powerful versions of CAR T cells that could attack these solid tumors,
while still keeping side effects in check. Members of the Lim laboratory are also working to reduce side effects by introducing multiple CARS into T cells
so that the cells will respond to multiple characteristics that are distinctive to an individual patient tumor,

Hackers sorry, security experts at mobile cybersecurity firm Lookout have compromised successfully a Tesla Model S. This is the third connected car hack in the last two weeks,
Mahaffey was quick to point out that this hack required"initial physical access to the car."
While the researcher commends Tesla for how well it separated its massive infotainment system from the rest of the car's controls at a top level,
Mahaffey and his partner in crime (for good) were able to perform any action possible from the car's touchscreen or Tesla's accompanying smartphone app.
On one occasion, the security guru successfully turned the car off while it was driving."
"At low speeds, the car applies the parking brake and it immediately comes to a stop,
"At speeds above about 5 miles per hour, the Model S gracefully shuts off its engineust like shifting a gasoline car into neutralhile still providing the driver full control over steering

especially when cars are only to become more connected? For starters, Mahaffey tells auto makers to start putting their cars'critical systems into closed networks that are isolated from the infotainment systems or information clusters.

It is all part of the promise of connected and self-driving cars, which allow data about individual journeys,
routes and vehicles to be monitored centrally, controlled and systematised. Autonomous intersection management Once computers are in full control of our cars,
do need we even traffic lights at intersections? That the idea behind AIM autonomous intersection management at the artificial intelligence laboratory at the University of Texas at Austin.
Rather than stop at red lights, self-driving cars would schedule a slot through an intersection in real-time,
speeding up or slowing down to ensure theye in the right place at the right time and not smashing into another car.
For the idea to work, it would require roads to be mostly full of autonomous cars, says project leader Professor Peter Stone

As we shift to more autonomous cars, that may have to change. One way self-driving vehicles may be introduced is latooning with a lead car in control of a train or group of followers, handy for giving lorry drivers a break.
Signals couldn be allowed to change midway through a platoon or it would leave stragglers behind. latoons would need to transmit their status to the intersection
or delayed to treat the platoon as a single long vehicle, said Alan Stevens, chief scientist and research director at transport firm TRL. ither the platoon could signal that it cleared the intersection
giving priority to one vehicle makes things slightly worse for all others. So, there little point in giving one or two connected private passenger vehicles special priority.
There are reasons to give some cars priority, and that being trialled by Newcastle. There, traffic lights are alkingto motorists,
sending messages to a device in car about obstacles or delays ahead, as well as helping them adjust their speeds to hit lights
when theye green. he system might advise a driver that if they travel at 24 miles an hour they will hit the next four sets of traffic lights on green,
then vehicles on key roads might be given priority in order to keep the traffic flowing. The system also gives priority to non-emergency vehicles,
such as those transporting people between hospitals, cutting NHS fuel costs and improving patient care. So far, 20 traffic lights are using the system in Newcastle city centre.

#Electric vehicle technology packs more punch in smaller package Using 3-D printing and novel semiconductors researchers at the Department of energy's Oak ridge National Laboratory have created a power inverter that could make electric vehicles lighter more powerful and more efficient.
At the core of this development is wide bandgap material made of silicon carbide with qualities superior to standard semiconductor materials.
Power inverters convert direct current into the alternating current that powers the vehicle. The Oak ridge inverter achieves much higher power density with a significant reduction in weight and volume.
which is the heart of an electric vehicle. Specific advantages of wide bandgap devices include: higher inherent reliability;
Building on the success of this prototype researchers are working on an inverter with an even greater percentage of 3-D printed parts that's half the size of inverters in commercially available vehicles.
Figuratively speaking these are genes that are like motor racing cars with a running engine waiting at the start of a race.
The new technology is designed for conventional lithium-ion batteries now used in billions of cellphones laptops and other electronic devices as well as a growing number of cars and airplanes.
But as the electric vehicle market expands and we start to replace onboard electronics on airplanes this will become a much larger problem Zhuo said.
Some electric cars today are equipped with thousands of lithium-ion battery cells. If one battery explodes the whole pack can potentially explode.
Expected to be the next big thing in battery technology this breakthrough has a wide-ranging impact on many industries especially for electric vehicles
This next generation of lithium-ion batteries will enable electric vehicles to charge 20 times faster than the current technology.
With it electric vehicles will also be able to do away with frequent battery replacements. The new battery will be able to endure more than 10000 charging cycles--20 times more than the current 500 cycles of today's batteries.
Ideally the charge time for batteries in electric vehicles should be less than 15 minutes which Prof Chen's nanostructured anode has proven to do.
and is currently developing new types of batteries for electric vehicle applications at the Energy Research Institute at NTU (ERI@N). Commercialisation of technologymoving forward Prof Chen's research team will be applying for a Proof-of-Concept
With our nanotechnology electric cars would be able to increase their range dramatically with just five minutes of charging
which is on par with the time needed to pump petrol for current cars added Prof Chen.
It is our vision for the future that such plants in the urban area are served by tank vehicles
In high-performance machines such as vehicle engines which are designed to run at high rotational speeds energy loss can be reduced by a few percentage points In high-torque electric motors such as those used to operate pumps the reduction in energy loss can be as high as twentyfive
