AbstractThe composites repair in the past was mostly for nonstructural applications. For the present emerging systems and to extend service life of structural members, repairs need to be made at the structural level. Several issues that are imuortant to bonded composite repair and its performance in realistic environmental conditions are discussed, Some of the recent work performed at the Air Force Materials Directorate is presented. The effects of surface preparation and laminate stacking sequence on strength of double-lap shear specimens are described.

With the increasing demand for renewable energy, alkali metal-ion (lithium/sodium/potassium-ion) batteries play more and more important roles in the field of static storage and electrical vehicle industry. Novel anode materials with high reversible capacity, safety and long-term cycling stability are desiderated to meet the ever-growing demand for alkali metal-ion batteries with high electrochemical performance. Antimony oxides (Sb x O y ) show electrochemical reaction activity with all of lithium, sodium and potassium, and are expected to be promising anode materials for alkali metal-ion storage due to their high theoretical capacities, appropriate operating potential and excellent safety properties. This review is devoted to overview the research progress on reaction mechanism and improvements in electrochemical performance of antimony oxides for alkali metal-ion storage, and look forward to their further prospects.
