"Yolk and Shell" Nanoparticles Could Make Batteries Last Longer
Aluminum powders were placed in sulfuric acid saturated with titanium oxysulfate. When the alumina reacts with sulfuric acid, excess water is released which reacts with titanium oxysulfate to form a solid shell of titanium hydroxide with a thickness of ...

Meet the Wearables Early Adopter Who Has Bought 8 Smartwatches — So Far
I made a few widgets and apps for personal use — things like a better calendar, better notifications, and an alarm clock — but the device never seemed to gain real traction. The Pebble came next. At first glance, it didn't seem that different from ...
What's the best way to measure, control and display?
That said, if they want alarm outputs, simply add a card, if they want communication to connect to the IIOT just add a card. In fact, they can change their minds long after they buy the machine and add cards once it is placed in the field. The plug-in ...

As batteries go through repeated charge-and-discharge cycles, their electrodes expand and contract—and the physical damage that causes leads to gradual battery degradation. The new advance is a nanoparticle, with a solid shell and a kind of “yolk” inside, that can be used as the electrode. It’s the yolk inside that can expand and contract, without affecting the size of the shell—which means that the macroscopic physical structure of the electrode doesn’t undergo the same stresses as usual. The nanoparticles use an aluminum yolk surrounded by a titanium dioxide shell. Current batteries typically use graphite at the electrode, because while it does degrade with expansion and contract, it’s not as bad as some other materials. Aluminum powders were placed in sulfuric acid saturated with titanium oxysulfate. When the alumina reacts with sulfuric acid, excess water is released which reacts with titanium oxysulfate to form a solid shell of titanium hydroxide with a thickness of 3 to 4 nanometers.

Department of Homeland Security’s principles and practices can help to prevent industrial control system incidents. The subject article in your July 2015 issue of Control Design by Dan Herbert (“Tear Down This Wall,” Control Design, July 2015, p20), has given me cause for concern as it ignores fundamental security issues that can be introduced when connecting... While the world is becoming more and more interconnected and “connecting machines to IT systems provides a number of benefits,” such connectivity, if not installed properly, can introduce many security challenges. These inter-connections can enable security vulnerabilities and potential pathways for compromise of the control environment by malicious threat actors.
