Psychological, social, and sexual challenges affecting men receiving male infertility treatment: a systematic review and implications for clinical care

In recent years, social research surrounding the consequences of infertility has increasingly focused on the male perspective;however, a gap exists in the understanding of men’s experiences of male infertility treatment. This review aims to synthesize theexisting evidence concerning the psychological, social, and sexual burden of male infertility treatment on men, as well as patientneeds during clinical care. A systematic search identified 12 studies that are diverse in design, setting, and methods. Psychologicalevaluations have found that urological surgery may have a lasting impact on infertility-specific stress, and treatment failure canlead to feelings of depression, grief, and inadequacy. Men tended to have an avoidant coping mechanism throughout fertilitytreatment, and their self-esteem, relationship quality, and sexual functions can be tied to outcomes of treatment. Partner bonds canbe strengthened by mutual support and enhanced communication;couple separation, however, has been noted as a predominantreason for discontinuing male infertility treatment and may be associated with difficult circumstances surrounding severe maleinfertility. Surgical treatments can affect the sexual functioning of infertile men;however, the impact of testicular sperm extractionoutcomes appears to be psychologically driven whereas the improvements after microsurgical varicocelectomy are only evident inhypogonadal men. Clinically, there is a need for better inclusion, communication, education, and resource provision, to addressreported issues of marginalization and uncertainty in men. Routine psychosocial screening in cases of severe male infertility andfollow-up in cases of surgical treatment failure are likely beneficial.

Highly active and durable Pd-Cu catalysts for oxygen reduction in alkaline exchange membrane fuel cells

引用

Frontiers in Energy 2017年第3期11卷 299-309页

作者： Xiong PENG Travis j. OMASTA justin M. ROLLER William E. MUSTAIN Department of Chemical and Biomolecular Engineering University of Connecticut 191 Auditorium Drive Storrs CT 06269 USA

A Pd-Cu catalyst, with primary B2-type phase, supported by VulcanXC-7R carbon was synthesized via a solvothermal method. The catalysts were physically and electrochemically characterized by X-ray diffraction （XRD）, X-ray photoelectron spectroscopy （XPS）, trans- mission electron microscopy （TEM） and both cyclic and linear sweep voltammetry using a rotating disk electrode （RDE）. During the RDE testing, the half-wave potential of the Pd-Cu/Vulcan catalyst was 50 mV higher compared to that of commercial Pt/C catalyst for the oxygen reduction reaction （ORR） in alkaline media. The Pd-Cu/Vulcan exhibited a specific activity of 1.27 mA/cm2 and a mass activity of 0.59 A/mgpd at 0.9 V, which were 4 and 3 times greater than that of the commercial Pt/C catalyst, respectively. The Pd-Cu/Vulcan catalyst also showed higher in-situ alkaline exchange membrane fuel cell （AEMFC） performance, with operating power densities of 1100 MW/cm2 operating on H2/O2 and 700 MW/cm2 operating on H2/Air （CO2-free）, which were markedly higher than those of the commercial Pt/C. The Pd-Cu/ Vulcan catalyst also exhibited high stability during a short-term, in-situ AEMFC durability test, with only around 11% performance loss after 30 hours of operation, an improve- ment over most AEMFCs reported in the literature to date.

Evaluating the performance of nanostructured materials as lithium-ion battery electrodes

引用

Nano Research 2014年第1期7卷 1-62页

作者： Mark j. Armstrong Colm O'Dwyer William j. Macklin justin. D. Holmes Materials Chemistry & Analysis Group Department of Chemistry and the Tyndall National Institute University College Cork Cork Ireland Applied Nanoscience Group Department of Chemistry and the Tyndall National Institute University College Cork Cork Ireland Centre for Research on Adaptive Nanostructures and Nanodevices (CRANN) Trinity College Dublin Dublin 2 Ireland Nexeon Limited Abingdon Oxfordshire UK.

The performance of the lithium-ion cell is heavily dependent on the ability of the host electrodes to accommodate and release Li＋ ions from the local structure. While the choice of electrode materials may define parameters such as cell potential and capacity, the process of intercalation may be physically limited by the rate of solid-state Li＋ diffusion. Increased diffusion rates in lithium-ion electrodes may be achieved through a reduction in the diffusion path, accomplished by a scaling of the respective electrode dimensions. In addition, some electrodes may undergo large volume changes associated with charging and discharging, the strain of which, may be better accommodated through nanostructuring. Failure of the host to accommodate such volume changes may lead to pulverisation of the local structure and a rapid loss of capacity. In this review article, we seek to highlight a number of significant gains in the development of nanostructured lithium-ion battery architectures （both anode and cathode）, as drivers of potential next-generation electrochemical energy storage devices.
