Analysis of physical evidence in police investigations by electron optical techniques has been performed in several laboratories in recent years. These studies have evolved in stages from exploratory evaluation of the viability of first SEM and then EDA analyses of samples, to extensive programs investigating certain classes of evidence materials, to detailed cataloging of the features and the results of large numbers of individual analyses within a class, to the ultimate test of the techniques, application in criminal investigations. During these studies, the following different general characteristics of the analyses emerged - analyses dependent upon the topography, those dependent upon the composition, and those dependent upon both composition and topography. In the experiences in our investigations (l-3), the number of analyses requiring some information from chemical composition were far greater than originally expected.

Contact X-ray imaging is presently developing as an important imaging technique in cell biology. Our recent studies on human platelets have demonstrated that the cytoskeleton of these cells contains photondense structures which can preferentially be imaged by soft X-ray imaging. Our present research has dealt with platelet activation, i.e., the complex phenomena which precede platelet appregation and are associated with profound changes in platelet cytoskeleton. Human platelets suspended in plasma were used. Whole cell mounts were fixed and dehydrated, then exposed to a stationary source of soft X-rays as previously described. Developed replicas and respective grids were studied by scanning electron microscopy (SEM).

Implantasi ion dapat meningkatkan sifat mekanik seperti kekerasan bahan yang akan digunakan untuk komponen dan peralatan proses manufaktur. Implantasi ion dipengaruhi oleh jenis ion dopan, waktu dan energi yang digunakan. Penelitian ini dilakukan untuk mengetahui pengaruh energi dan waktu implantasi ion titanium nitrida terhadap kekerasan dan struktur mikro pada baja VCL 140. Implantasi dilakukan pada arus berkas tetap 10 yA. Variasi waktu 60, 70, 80, 90, 100, 110, 120 menit, energi 75 keV dan variasi energi 15, 30, 45, 60, 75, 90 dan 100 keV dengan waktu implantasi 100 menit dilakukan untuk mendapatkan kekerasan optimum. Uji Kekerasan menggunakan metode Vickers dengan beban 10 gram dan waktu 10 detik. Topografi dari lapisan TIN diamati menggunakan scanning electron microscopy (SEM) dan komposisi kimia dari lapisan TIN dianalisa menggunakan energy dispersive spectroscopy (EDS).Kata kunci : Implantasi ion, VCL 140, kekerasan
