Morphology-dependent performance of CuO anodes via facile and controllable synthesis for lithium-ion batteries.

ACS applied materials & interfaces

Wang C, Li Q, Wang F, Xia G, Liu R, Li D, Li N, Spendelow JS, Wu G.
PMID: 24377276
ACS Appl Mater Interfaces. 2014 Jan 22;6(2):1243-50. doi: 10.1021/am405061c. Epub 2014 Jan 07.

Nanostructured CuO anode materials with controllable morphologies have been successfully synthesized via a facile and environmentally friendly approach in the absence of any toxic surfactants or templates. In particular, leaf-like CuO, oatmeal-like CuO, and hollow-spherical CuO were obtained by...

Self-assembled reduced graphene oxide/polyacrylamide conductive composite films.

ACS applied materials & interfaces

Yu S, Li N, Higgins D, Li D, Li Q, Xu H, Spendelow JS, Wu G.
PMID: 25329422
ACS Appl Mater Interfaces. 2014 Nov 26;6(22):19783-90. doi: 10.1021/am504941p. Epub 2014 Nov 05.

Substrate supported conductive thin films are prepared by the self-assembly of graphene oxide (GO) on a cationic polyacrylamide (CPAM) layer followed by a subsequent chemical reduction. During self-assembly, the dispersed GO nanosheets with a negative zeta potential from solution...

We report in this article a detailed study on how to stabilize a first-row transition metal (M) in an intermetallic L1

Mechanism of CO oxidation on Pt(111) in alkaline media.

The journal of physical chemistry. B

Spendelow JS, Goodpaster JD, Kenis PJ, Wieckowski A.
PMID: 16686501
J Phys Chem B. 2006 May 18;110(19):9545-55. doi: 10.1021/jp060100c.

Electrochemical techniques, coupled with in situ scanning tunneling microscopy, have been used to examine the mechanism of CO oxidation and the role of surface structure in promoting CO oxidation on well-ordered and disordered Pt(111) in aqueous NaOH solutions. Oxidation...

Advanced Nanocarbons for Enhanced Performance and Durability of Platinum Catalysts in Proton Exchange Membrane Fuel Cells.

Small (Weinheim an der Bergstrasse, Germany)

Qiao Z, Wang C, Zeng Y, Spendelow JS, Wu G.
PMID: 34061449
Small. 2021 Dec;17(48):e2006805. doi: 10.1002/smll.202006805. Epub 2021 Jun 01.

Insufficient stability of current carbon supported Pt and Pt alloy catalysts is a significant barrier for proton-exchange membrane fuel cells (PEMFCs). As a primary degradation cause to trigger Pt nanoparticle migration, dissolution, and aggregation, carbon corrosion remains a significant...

Ordered Pt.

Membranes

Houchins C, Kleen GJ, Spendelow JS, Kopasz J, Peterson D, Garland NL, Ho DL, Marcinkoski J, Martin KE, Tyler R, Papageorgopoulos DC.
PMID: 24958432
Membranes (Basel). 2012 Dec 18;2(4):855-78. doi: 10.3390/membranes2040855.

Low cost, durable, and selective membranes with high ionic conductivity are a priority need for wide-spread adoption of polymer electrolyte membrane fuel cells (PEMFCs) and direct methanol fuel cells (DMFCs). Electrolyte membranes are a major cost component of PEMFC...

Begging behavior as an honest signal of need and parent-offspring association during the postfledging dependency period.

Ecology and evolution

Davis KL, Karpanty SM, Spendelow JA, Cohen JB, Althouse MA, Parsons KC, Luttazi CF.
PMID: 31346418
Ecol Evol. 2019 Jun 17;9(13):7497-7508. doi: 10.1002/ece3.5279. eCollection 2019 Jul.

Honest signaling mechanisms can function to appropriate care to hungry offspring and avoid misdirected care of unrelated offspring. Begging, the behavior by which offspring solicit food and parental care, may be an honest signaling mechanism for need, as well...

Nitrogen-Coordinated Single Cobalt Atom Catalysts for Oxygen Reduction in Proton Exchange Membrane Fuel Cells.

Advanced materials (Deerfield Beach, Fla.)

Adv Mater. 2018 Mar;30(11). doi: 10.1002/adma.201706758. Epub 2018 Jan 24.

Due to the Fenton reaction, the presence of Fe and peroxide in electrodes generates free radicals causing serious degradation of the organic ionomer and the membrane. Pt-free and Fe-free cathode catalysts therefore are urgently needed for durable and inexpensive...
