A method of providing a condition report for a vehicle using a mobile device including a display includes constructing a plurality of condition report sections using a condition report application database residing in a cloud based server service and infrastructure to process requests from the mobile device including: capturing data, on the mobile device, for constructing at least one condition report section of the plurality of condition report sections; and accessing, from the mobile device, a condition report document database and/or a condition report images database residing in the cloud based server service and infrastructure for constructing and storing the plurality of condition report sections. The method includes providing user input indicative that the plurality of condition report sections have been completed, and providing user input indicative of a decision to publish the completed condition report sections as the condition report for the vehicle. The published condition report is viewable by a party by an Internet accessible web browsing device.

Organometal trihalide perovskite solar cells (PSCs) have garnered recent interest in the scientific community. In the past few years, they have achieved power conversion efficiencies comparable to traditional commercial solar cells (e.g., crystalline Si, CuInGaSe and CdTe) due to their low-cost of production via solution-processed fabrication techniques. However, the stability of PSCs must be addressed before their commercialization is viable. Among various kinds of PSCs, carbon-based PSCs without hole transport materials (C-PSCs) seem to be the most promising for addressing the stability issue because carbon materials are stable, inert to ion migration (which originates from perovskite and metal electrodes), and inherently water-resistant. Despite the significant development of C-PSCs since they were first reported in 2013, some pending issues still need to be addressed to increase their commercial competitiveness. Herein, recent developments in C-PSCs, including (1) device structure and working principles, (2) categorical progress of and comparison between meso C-PSCs, embedment C-PSCs and paintable PSCs, are reviewed. Promising research directions are then suggested (e.g., materials, interfaces, structure, stability measurement and scaling-up of production) to further improve and promote the commercialization of C-PSCs. © 2017 WILEY-VCH Verlag GmbH & Co.

The addition of transition metals, even in a trace amount, into heteroatom-doped carbon (M-N/C) is intensively investigated to further enhance oxygen reduction reaction (ORR) activity. However, the influence of metal decoration on the electrolysis of the reverse reaction of ORR, that is, oxygen evolution reaction (OER), is seldom reported. Moreover, further improving the bifunctional activity and corrosion tolerance for carbon-based materials remains a big challenge, especially in OER potential regions. Here, bimetal-decorated, pyridinic N-dominated large-size carbon tubes (MM′-N/C) are proposed for the first time as highly efficient and durable ORR and OER catalysts. FeFe-N/C, CoCo-N/C, NiNi-N/C, MnMn-N/C, FeCo-N/C, NiFe-N/C, FeMn-N/C, CoNi-N/C, MnCo-N/C, and NiMn-N/C are systematically investigated in terms of their structure, composition, morphology, surface area, and active site densities. In contrast to conventional monometal and N-decorated carbon, small amounts of bimetal (≈2 at%) added during the one-step template-free synthesis contribute to increased pyridinic N content, much longer and more robust carbon tubes, reduced metal particle size, and stronger coupling between the encapsulated metals and carbon support. The synergy of those factors accounts for the dramatically improved ORR and OER activity and stability. By comparison, NiFe-N/C and MnCo-N/C stand out and achieve superior bifunctional oxygen catalytic performance, exceeding most of state-of-the-art catalysts. © 2017 WILEY-VCH Verlag GmbH & Co.

The use of additives for organic synthesis has become a common tactic to improve the outcome of organic reactions. Herein, by using an organocatalytic process for the synthesis of chiral diarylmethyl alkynes as a platform, we describe how an additive is involved in the improvement of the process. The evolution of an excellent synthetic protocol has been achieved in three stages, from 1)initially no catalyst turnover, to 2)good conversion and enantioselectivity with a superior additive, and eventually 3)even better efficiency and selectivity without an additive. This study is an important and rare demonstration that understanding the role of additive can be so beneficial as to obviate the need for the additive. © 2017 Wiley-VCH Verlag GmbH & Co.

In this paper, we report a facile ultrasonic method to synthesize well-dispersed CoO quantum dots (3-8 nm) on graphene nanosheets at room temperature by employing Co 4(CO) 12 as cobalt precursor. The prepared CoO/graphene composites displayed high performance as an anode material for lithium-ion battery, such as high reversible lithium storage capacity (1592 mAh g -1 after 50 cycles), high Coulombic efficiency (over 95%), excellent cycling stability, and high rate capability (1008 mAh g -1 with a total retention of 77.6% after 50 cycles at a current density of 1000 mA g -1, dramatically increased from the initial 50 mA g -1). The extraordinary performance arises from the structure advantages of the composites: the nanosized CoO quantum dots with high dispersity on conductive graphene substrates supply not only large quantity of accessible active sites for lithium-ion insertion but also good conductivity and short diffusion length for lithium ions, which are beneficial for high capacity and rate capability. Meanwhile, the isolated CoO quantum dots anchored tightly on the graphene nanosheets can effectively circumvent the volume expansion/contraction associated with lithium insertion/extraction during discharge/charge processes, which is good for high capacity as well as cycling stability. Moreover, regarding the anomalous behavior of capacity increase with cycles (activation effect) observed, we proposed a tentative hypothesis stressing the competition between the conductivity increase and the amorphorization of the composite electrodes during cycling in determining the trends of the capacity, in the hope to gain a fuller understanding of the inner working of the novel nanostructured electrode-based lithium-ion batteries. © 2012 American Chemical Society.

An intelligent gas flow sensor probe which outputs a state signal indicating whether there is forced gas flow present within a conduit or whether there is no gas flow. The intelligent gas flow sensor probe includes a heated thermistor and a reference thermistor functionally coupled to a microcontroller. The heated thermistor is continuously heated at a constant rate to a temperature above an ambient temperature within the conduit and outputs a signal responsive to a change in temperature induced by gas flow incident thereupon. Gas flow within the conduit causes heat to be transferred from the heated thermistor to the gas flowing over and/or around the heated thermistor. The reference thermistor is thermally insulated from the heated thermistor and outputs a reference signal responsive to an ambient temperature of the gas within the conduit. The reference thermistor is used to differentiate between forced gas flow and ambient gas flow based on historically obtained temperature data values because flow state determinations are based on real time data which are independent of component tolerances.
