Hawking–Bekenstein entropy formula seems to tell us that no quantum degrees of freedom can reside in the interior of a black hole. We suggest that this is a consequence of the fact that the volume of any interior sphere of finite surface area simply vanishes. Obviously, this is not the case in general relativity. However, we show that such a phenomenon does occur in various gravitational theories which admit a spontaneously induced general relativity. In such theories, due to a phase transition (one-parameter family degenerates) which takes place precisely at the would-have-been horizon, the recovered exterior Schwarzschild solution connects, by means of a self-similar transition profile, with a novel "hollow" interior exhibiting a vanishing spatial volume and a locally varying Newton constant. This constitutes the so-called "hollowgraphy" driven holography.

Among the local finds displayed in the Museum of Antiquities at the Piraeus are six Roman portraits, all of Pentelic marble and all unrestored. Two of them, a colossal head of Trajan (no. 270) and a colossal statue of Balbinus (no. 278), have already been fully edited. But according to the Director of the Piraeus Museum, Dr. Threpsiades, and to the best of the present writer's knowledge, of the other portraits two are still unpublished, two described without any illustration; and it is with Dr. Threpsiades' kind permission that all four are published here.I. No. E 4. Head of Claudius(Plate 67a–b)Total height: 48 cm.Height from crown of head to bottom of chin: 26 cm.Width across at greatest extent: 20 cm.Width from back to front at greatest extent: 24 cm.The sculpture depicts the head and neck, slightly over life-size, of an elderly man, in whom we can immediately recognize the Emperor Claudius. At the base of the neck is a rounded ‘tenon’, designed for insertion into a cavity between the shoulders of the now vanished body of a full-length statue. Claudius' face has sustained considerable damage. The nose has practically gone, only part of the side, and the hollow interior, of the right nostril remaining. The chin, lips, and right ear are bruised, the brow is marred by several abrasures, and the left ear is lost.

Specific Surface Areas

Fiber structures with nanoscale diameters offer many fascinating features, such as excellent mechanical properties and high specific surface areas, making them attractive for many applications. Among a variety of technologies for preparing nanofibers, electrospinning is rapidly evolving into a simple process, which is capable of forming diverse morphologies due to its flexibility, functionality, and simplicity. In such review, more emphasis is put on the construction of polymer nanofiber structures and their potential applications. Other issues of electrospinning device, mechanism, and prospects, are also discussed. Specifically, by carefully regulating the operating condition, modifying needle device, optimizing properties of the polymer solutions, some unique structures of core–shell, side-by-side, multilayer, hollow interior, and high porosity can be obtained. Taken together, these well-organized polymer nanofibers can be of great interest in biomedicine, nutrition, bioengineering, pharmaceutics, and healthcare applications.

Hollow and hierarchical NiO nanosheets nanotubes were successfully prepared through a one-step solvothermal route followed by a thermal annealing treatment. The microstructure and chemical composition of Ni-precursor@PNT core-shell nanostructures and calcined NiO nanosheets nanotubes are investigated by SEM, TEM, TGA and XRD. The unique NiO nanosheets nanotubes show admirable electrochemical performance as an electrode material for supercapacitors owing to the hierarchically tubular structures and hollow interior.

AbstractIn this communication, hollow bioactive glass (BG) nanofibers were fabricated via a single-nozzle electrospinning method. The morphology of the prepared hollow BG nanofibers was observed by SEM and TEM, and the results showed that BG nanofibers had a continuous hollow interior. The hollow BG nanofibers were incubated in simulated body fluid (SBF) to investigate their apatitemineralization ability, and the result showed that after incubation for 6 h a flower-like apatite was observed on the surface of hollowBGnanofibers, and the Fourier transform infrared (FTIR) result further confirmed the formation of apatite. The results suggested that hollow BG nanofibers could be used for drug delivery and bone regeneration applications due to their unique hollow structure and bioactivity.
