Rapid consolidation of powdered materials by induction hot pressing

A rapid hot press system in which the heat is supplied by RF induction to rapidly consolidate thermoelectric materials is described. Use of RF induction heating enables rapid heating and consolidation of powdered materials over a wide temperature range. Such rapid consolidation in nanomaterials is typically performed by spark plasma sintering (SPS) which can be much more expensive. Details of the system design, instrumentation, and performance using a thermoelectric material as an example are reported. The Seebeck coefficient, electrical resistivity, and thermal diffusivity of thermoelectric PbTe material pressed at an optimized temperature and time in this system are shown to agree with material consolidated under typical consolidation parameters.     

A high temperature apparatus for measurement of the Seebeck coefficient

A high temperature Seebeck coefficient measurement apparatus with various features to minimize typical sources of error is designed and built. Common sources of temperature and voltage measurement error are described and principles to overcome these are proposed. With these guiding principles, a high temperature Seebeck measurement apparatus with a uniaxial 4-point contact geometry is designed to operate from room temperature to over 1200 K. This instrument design is simple to operate, and suitable for bulk samples with a broad range of physical types and shapes.     

Bovine muscle shortening and protein degradation after electrical stimulation, excision and chilling

Electrical stimulation-dependent improvement in beef tenderness resulted from mechanisms other than avoidance of cold shortening in excised muscle chilled at a normal rate (10°C at 10h post-stimulation). At normal chilling rate, electrical stimulation enhanced degradation of the myofibrillar proteins, alpha actinin and troponin-T, and increased the amount of a 30 000 dalton protein, as assessed by gel electrophoresis, whereas sarcomere lengths were not different from unstimulated muscle. Under slightly accelerated chilling conditions (10°C at 5 h post stimulation), electrical stimulation prevented cold shortening but the meat was more tender than, and had the same sarcomere length as, unstimulated muscle chilled to 10°C in 10 h. Electrical stimulation did not improve the tenderness of beef chilled at a rapid rate (10°C at 2 h post stimulation), nor did it prevent cold shortening when muscles were chilled rapidly.     

驼峰型金属针布优点探析

介绍了驼峰型锡林针布、刺辊针布的规格参数,分析了其外形特点。通过对比驼峰型锡林针布与普通锡林针布纺纱指标,指出该锡林针布使精梳纱棉结显著减少,但不匀率及粗、细节无明显变化;刺辊针布可在梳棉早期排除不成熟纤维、死纤维,使下游产品棉结显著减少。

Superbaba餐厅

正Superbaba餐厅的设计灵感实际来源于四位餐厅负责人,不管是过往的家庭经历,还是中东地区店面常见的标识,以及看到的过度饱和的食物照片,都为设计师带来了设计灵感。设计师将这些元素糅合在一起,打造一个抓人眼球的、友好的艺术空间。在有限的经费下,创造性的材料运用与细节处理尤为重要。在Superbaba餐厅内部,设计师运用到了很多传统中东建筑中色彩
