Third Century AD Burial Vaults from the Cemetery of Opushki

open access: yesНижневолжский археологический вестник
There was some important event taking place in the Crimea in the third century AD or a little bit earlier that was probably reflected by the appearance of burial vaults of a special design that had not been previously known in Crimea.

Laser‐Based Sculpturing of Embedded Ultrathin Metal‐Oxide Nanopores for Enhanced Biomolecular Sensing

open access: yesAdvanced Functional Materials, EarlyView.
Controlled laser‐drilling of embedded HfO2 membranes creates three layer nanopores with Gaussian‐shaped cavities sculptured in the supporting layers. These embedded solid‐state nanopores slow DNA translocation by 12‐fold compared to SiNx pores, enabling high‐resolution, label‐free detection of short DNAs, RNAs, and proteins.

Spectroscopic characterization of Phoenician-Punic coins [PDF]

open access: yes, 2013
Sardinia hosted many Phoenician and Punic communities, as integrated forms of pacific cohabitation with the Lebanese merchants or actual colonies for the exploitation of the rich mines and wealthy coastal emporia under the Carthaginians (750-250 B.C ...

A Single‐Metal‐Doped Nanoplatform for Ferroptosis‐Driven cGAS‐STING Pathway Activation in Hepatocellular Carcinoma Immunotherapy

open access: yesAdvanced Functional Materials, EarlyView.
The cGAS‐STING pathway boosts HCC antitumor immunity but lacks specific activation. Nanoplatform ZMRPF induces HCC ferroptosis via lipid ROS, releasing mtDNA. It synergizes with ZMRPF‐released Mn2⁺ to activate cGAS‐STING, amplifies antigen‐presenting cell activity, reverses HCC immunosuppression, and enables robust systemic antitumor immunity ...

Nález sklenej perly z prikostolného cintorína sv. Vavrinca v Bratislave

open access: yesArchaeologia Historica, 2014
Pri výskume Kaplnky sv. Jakuba na Námestí SNP v Bratislave v roku 1994 sa našla sklená perla z ruženca. Nález pochádza z Cintorína sv. Vavrinca, no nenašiel sa priamo v hrobovom kontexte, ale vo vrstve obsahujúcej množstvo kostrových pozostatkov.

4D Printing of Self‐Immolative Polymers

open access: yesAdvanced Functional Materials, EarlyView.
The integration of self‐immolative polymers (SIPs) into light‐based 3D printed structures is presented as a new “living” 4D printing strategy. By exploiting their metastability and stimuli‐responsiveness, SIP‐containing printed objects can undergo rapid and triggered degrowth under ambient conditions and subsequent regrowth through polymer ...
