All‐in‐One Analog AI Hardware: On‐Chip Training and Inference with Conductive‐Metal‐Oxide/HfOx ReRAM Devices

Advanced Functional Materials, EarlyView.
An all‐in‐one analog AI accelerator is presented, enabling on‐chip training, weight retention, and long‐term inference acceleration. It leverages a BEOL‐integrated CMO/HfOx ReRAM array with low‐voltage operation (<1.5 V), multi‐bit capability over 32 states, low programming noise (10 nS), and near‐ideal weight transfer.

Biodegradable and Recyclable Luminescent Mixed‐Matrix‐Membranes, Hydrogels, and Cryogels based on Nanoscale Metal‐Organic Frameworks and Biopolymers

Advanced Functional Materials, EarlyView.
The study presents biodegradable and recyclable mixed‐matrix membranes (MMMs), hydrogels, and cryogels using luminescent nanoscale metal‐organic frameworks (nMOFs) and biopolymers. These bio‐nMOF‐MMMs combine europium‐based nMOFs as probes for the status of the materials with the biopolymers agar and gelatine and present alternatives to conventional ...

Modulating Two‐Photon Absorption in a Pyrene‐Based MOF Series: An In‐Depth Investigation of Structure–Property Relationships

Advanced Functional Materials, EarlyView.
This study investigates H4TBAPy‐based metal–organic frameworks (MOFs) ‐ NU‐1000, NU‐901, SrTBAPy, and BaTBAPy ‐ for multiphoton absorption (MPA) performance. It observes topology‐dependent variations in the 2PA cross‐section, with BaTBAPy exhibiting the highest activity.

Equipment for Electron Irradiations

Radiation Research, 1956
to the sample and from the average energy of the electrons. This technique is usable only when there are ample amounts (gram quantities) of material available so that the entire electron beam may be stopped in the sample itself. Pollard and co-workers (3) have irradiated enzymes by allowing an electron beam to pass entirely through the sample; however,

Luminescence from electron-irradiated sapphire

Physical Review B, 1993
Point defects have been produced by electron irradiation in single-crystal \ensuremath{\alpha}-${\mathrm{Al}}_{2}$${\mathrm{O}}_{3}$ from two different sources. Time-resolved luminescence spectroscopy has been used to study emission spectra and atomic-displacement thresholds for the defects.

Tsukuba electron irradiation facility

International Journal of Radiation Applications and Instrumentation. Part C. Radiation Physics and Chemistry, 1990
Abstract An electron irradiation center for research and development of the electron beam processing technology is under construction at Tsukuba, the city of science and technology consisting of many research laboratories and institutes of government and private industries. It is located near Tokyo. A 5 MeV, 150 kw Dynamitron which already has proved

Electron irradiation of polyacrylates

Journal of Polymer Science, 1956
AbstractThe crosslinking and degradation of seven polyacrylates by 1000 kvp. electrons has been investigated. Gel content‐radiation dose analysis reveals the energy dissipation per main‐chain fracture, Ed, to be the same (530 ± 100 electron volts) for methyl, n‐butyl, sec‐butyl, isobutyl, and tert‐butyl acrylate polymers.

Electron Irradiation of Zeolites

MRS Proceedings, 1998
AbstractThree different zeolites (analcime, natrolite, and zeolite-Y) were irradiated with 200 keV and 400 keV electrons. All zeolites amorphized under a relatively low electron fluence. The transformation from the crystalline-to-amorphous state was continuous and homogeneous.

Electron Irradiation of Polythene

Nature, 1954
CONSIDERABLE attention has recently been given to the effects of high-energy radiation on polymeric substances1. The effects would appear to be of the same fundamental character whether X-rays, electron bombardment, or the mixed radiations of the atomic pile are used; it is reported that in the absence of oxygen the dominant reactions are either cross ...

Electron Spin Resonance of Irradiated DNA

The Journal of Chemical Physics, 1963
The electron spin resonance (ESR) spectra of free radicals formed in-the sodium salt of desoxyribonucleic acid (DNA) by 1-Mev electrons were examined. Dry samples were irradiated at approximates 200°K and examined at 77°K at microwave power levels below approximates 0.1 mw. At levels below 1 Mrad only a single, rather broad absorption line was seen. At
