TL;DR: To provide useful insights into the future directions of bionanofabrication, current developments in characterization techniques, fabrication methods, and their integration and control in manufacturing processes are discussed.

TL;DR: A new method to fabricate semiconducting, transition metal nanoparticles (NPs) with tunable bandgap energies using engineered Escherichia coli to facilitate precipitation of cadmium sulphide (CdS) NPs suggests that bacterially precipitated CdS NPs have potential for applications ranging from photovoltaics to photocatalysis in hydrogen evolution.

TL;DR: A combined density functional theory and continuum modeling approach is introduced that yields sub-surface-sensitive, nanomechanical fingerprints associated with specific, well-defined structure models of individual surface domains where such models are known and can be correlated with experimentally obtained contact-resonance frequency maps to reveal the (sub)surface structure of different domains on the sample.

TL;DR: At present, the development of μ CP has exceeded the original aim of transferring a single-stamp feature pattern onto a surface and some new patterns that do not exist on the original stamp could be achieved by extending μ CP of a physical deformation via lateral compression or solvent swelling to a stamp.

Abstract: In Part I, the theory of hydrogen-bond-dominated solids is extended to explain phenomena concerning the elastic behavior of paper, based on the postulate that the number density of effective hydrogen bonds, normalized to an average bond stiffness, is higher for ultrasonic modulus measurements. This leads to the predictions : (1) The measured elastic modulus of a sheet of paper will depend upon whether the modulus is measured quasi-statically using load-elongation methods or ultrasonically using the time of flight method, and that the ultrasonic modulus, E u , will exceed the quasi-static modulus, E s , (E u > E s ). (2) The rate of change of modulus with increasing moisture content, w, follows the rule : In[E] = A-(C.I.)w, where the negative slope of the curve In[E] vs. w is constant over a wide range of moisture contents. But again this slope will also differ whether measured quasi-statically or ultrasonically, with (C.I.) s > (C.I.) u . (3) Moreover, the extended theory predicts that the ratio of moduli at zero moisture content is related to the ratio of slopes by the expression: {[E 0 ] u /[E 0 ] s } 3 = [(C.I.) s +I]/[(C.I.) u +I].
