Recovering the CTR_DRBG state in 256 traces

Transactions on Cryptographic Hardware and Embedded Systems, 2019
The NIST CTR_DRBG specification prescribes a maximum size on each random number request, limiting the number of encryptions in CTR mode with the same key to 4 096.

Surface Deposition of Dome‐Shaped Metal‐Organic Complexes: A New Approach to the Generation of Single‐Site Catalysts

ChemPlusChem, EarlyView.
This study describes the synthesis of a new dithia‐[2.1.1]‐(2,6)‐pyridinophane ligand and its molybdenum(0) tricarbonyl complex. Monolayers of the dome‐shaped complex on Au(111) are investigated by employing surface spectroscopic methods (infrared reflection absorption spectroscopy, X‐ray photoelectron spectroscopy, near‐edge X‐ray absorption fine ...

Trifluoroacetylated Trimethine, Pentamethine, and Heptamethine Cyanine Dyes: Syntheses, Structures, and Photochemical Properties

ChemPhotoChem, EarlyView.
Herein, the rapid, concise, and straightforward synthesis of trifluoroacetylated trimethine, pentamethine, and heptamethine cyanine dyes is reported via the direct trifluoroacetylation of trimethine, pentamethine, and heptamethine cyanine dyes using commercially available trifluoroacetic anhydride.

Itaconic Anhydride as a Novel Bio‐Derived Solid Electrolyte Interphase Forming Additive for Lithium‐Ion Batteries

ChemSusChem, EarlyView.
This work presents itaconic anhydride as a novel bio‐derived additive able to form a suitable solid electrolyte interphase on graphite anodes and demonstrating similar performance to that of vinylene carbonate. Further, its decomposition mechanisms are investigated and a plausible pathway for solid electrolyte interphase formation is proposed.

Identification and Investigation of the Intrinsic Receptor Activation Potential and Metabolization of the New Oxo‐Pyridyl Synthetic Cannabinoid Receptor Agonist CH‐FUBBMPDORA

Drug Testing and Analysis, EarlyView.
Another Chinese generic ban‐evading SCRA, CH‐FUBBMPDORA, has emerged. This study reports its first identification in Europe, its analytical characterization (NMR, Raman, FTIR, GC–MS, and HRMS), its cannabinoid activation potential in a βarr2 recruitment assay, and its metabolization profile.

Identification of Three Novel Tetrahydrocannabinol Analogs in the European Market

Drug Testing and Analysis, EarlyView.
The major isolated ingredient of “CB9” was identified as [2‐(E)‐propen‐1‐yl]‐Δ8‐tetrahydrocannabinol‐acetate of “tresconol” as [2‐propen‐2‐yl]‐Δ9‐tetrahydrocannabinol and of “CBx” as [2‐propen‐2‐yl]‐Δ8‐tetrahydrocannabinol. These compounds have no available spectroscopic or chromatographic data and have never been identified in Cannabis plants, and ...
