🗞️ Our latest paper has just been published in ACS Applied Materials & Interfaces: "Silver Sulfobenzoate Coordination Polymers as Bioactive Dopants in Antibacterial and Antibiofilm Cellulose Films." ⚗️

Antimicrobial resistance is a critical global health threat, driving the urgent need for new materials to inhibit bacteria and biofilm growth. This study develops advanced antibacterial films by doping renewable biopolymers with two new bioactive silver(I) coordination polymers.

By tailoring these compounds, we created hybrid materials with controlled silver release. These innovative films achieved a remarkable 99.97% reduction in biofilm growth against major Gram-positive and Gram-negative bacteria, offering a powerful weapon for medical devices and clinical applications. 🧫

A grateful appreciation for this team's determination and commitment:

“Bio Digital Jazz” is a swirling vortex of crimson cells contained in a digital cube. As they spiral toward the center, the bright arterial red grabs focus against a screaming blue and electric yellow that dance off the canvas, balanced by yellow-green mid-tones. Every piece in this series is freehanded and freely mixed—a visual jam session, each stroke a note, each color an improvisation.

The title echoes a truth from the grid: “The Isos… bio-digital jazz, man.” It asks what happens when technology doesn’t replace life, but plays it like an instrument. When medicine and machine find a new rhythm.

Now, it’s your turn to look. What do you hear?

🔵 👇 SE(A) BELOW:
“the morse code of water birds”

When we look at a landscape - the water’s surface with birds and the way they gather - do they form letters? As if they want to tell us something.
The artwork shows a landscape in a blue haze: sea, distant mountains. Black silhouettes of birds appear in the foreground, transforming into names through typography; farther away, the birds are rendered through Morse code.

I selected several bird species I find interesting or personally meaningful - se(a) below. Their names aren’t placed randomly. The first letters form an acrostic spelling SEA ABOVE - referring both to the sea depicted above this section and to the spoken SEE, inviting the viewer to look upward.
In the distance, the birds appear as Morse code. Read from the top, it says: FOLLOW THE HERON. In ancient Egypt, the deity Bennu was depicted as a heron and symbolized rebirth, so the message invites us toward new beginnings and transformation. Interestingly, there’s even an asteroid, 101955 Bennu.
𓅣
•Seagull – I love all gulls, some species even live in my city. In Czech, the black-headed gull is called ‘racek chechtavý’, meaning ‘laughing gull’
•Egret – all egrets are herons, but not all herons are egrets. In Czechia, the most common heron is the grey heron, which was the symbol of Bennu in ancient Egypt. The ancient Egyptian verb ‘wbn’, associated with Bennu, carries the meaning ‘to rise’.
•Albatross – also the name of a Czech publishing house; hint at the literature and linguistics I later studied
•Arctic loon – black-and-white plumage like a chessboard or typography
•Blue-footed booby – blue feet from its diet; males show feet in a comic courtship strut
•Orange-billed tern – the genus Thalasseus (from the Ancient Greek Thalassa, meaning ‘sea’) includes, for example, the Sandwich tern which doesn’t have the orange bill, but I like the name. Their black head markings resemble cool hairstyles, a bit metal-band
•Variable oystercatcher – opens shells, like courage that cracks our own shell and lets the world in
•Eurasian coot – bobs its head as it swims, like walking to music, a reminder to have fun and choose your own 'soundtrack for life'.

Ethereal Recall by @mau774
Ink,pencil on canson paper

A humanoid composed of irregular crystalline or polygonal fragments, resembling shards of glass or glitched pixels, is not a fluid organic form, but rather rigid and angular, with a body that seems on the verge of disintegration.
It represents the technological fragmentation of human identity. In an era dominated by AI and digital technology, the human being is no longer whole: it is "splintered" into data, algorithms, and virtual representations. The crystals evoke the coldness and illusory transparency of technology (such as screens or liquid crystals), but also fragility—a reminder of the loss of authenticity. It is a symbol of alienation: man becomes an artificial construct, distant from his biological and emotional essence.
The entire drawing is set against a completely white, minimalist background, devoid of contextual or environmental elements; this void symbolizes isolation in the age of AI and the virtual. The white represents digital "nothingness"—an ethereal space, infinite but devoid of human warmth, like a cyber limbo or an empty cloud. It reinforces the sense of alienation: the figure is alone, without real connections, immersed in an artificial world where relationships are mediated by screens. It's an intentional contrast with the complexity of the figure, emphasizing how technology creates an illusion of connection in an existential void.

"Ethereal" suggests something immaterial and transitory, like digital memories or AI entities floating in cyberspace. "Recall" can mean both "recall" (nostalgia) and "withdrawal" (like a defective product), implying that "technologized" humanity is a mistake to be corrected. The work explores the alienation caused by AI and the loss of human authenticity, and invites us to reflect on how technology fragments the soul, rendering it ethereal yet ephemeral.

🌞Ciao a tuttə!

⛰️Qualche giorno fa, in alcuni post che ho pubblicato accennavo a uno speciale incontro avvenuto mentre ero in giro per l’Aspromonte con il mio amico. Era mia intenzione raccontarvelo tramite un’illustrazione ad acquerelli ed eccomi qui!

🖌️ Non è un dipinto di cui sono soddisfatto, ma ne sono felice perché il risultato finale sembra un po’ impressionista, come il momento di cui io e il mio amico siamo stati testimoni: un incontro fugace, di un solo incredibile istante, con un maschio di Capriolo italico. Nelle slide vi racconto di quel momento, il cui ricordo sarà per me uno dei più speciali per sempre.

🦌Qui in descrizione, invece, ho piacere di parlarvi di come l’incontro con un capriolo in Aspromonte sia veramente speciale e raro poiché la sua presenza, in quella terra di aspri boschi di montagna, è dovuta a una reintroduzione avvenuta fra il 2008 e il 2011 grazie al Piano d’Azione Nazionale per il Capriolo italico (ISPRA) e allo studio condotto da D.R.E.AM. Italia su incarico del Parco Nazionale dell’Aspromonte. In quel segmento di tempo sono stati reintrodotti settantacinque individui della sottospecie Capreolus capreolus italicus, per ripopolare il territorio di questa meravigliosa specie, che mancava dai boschi aspromontani da circa un secolo. Negli anni, per altro, l’avvistamento di diversi cuccioli conferma la riuscita del piano a seguito della riproduzione degli esemplari.. non è una gioia quando questo accade? La presenza del capriolo porta al funzionamento ecologico di un habitat che senza di noi forse non avrebbe mai dovuto subire tante catastrofi ed è per questo che tali progetti non solo vanno promossi e sostenuti, ma rispettati con un comportamento adeguato e rispettoso nei confronti della fauna e del suo habitat, nel quale noi non siamo che ospiti.

🌲Voi sapevate della presenza del capriolo italico in Aspromonte? Ne avete mai avvistato uno da quelle parti?

🫂Vi abbraccio!

Crystal Engineering: The Art of Designing Crystalline Solids.
This post showcases our recent research featured on a Cover of CrystEngComm.

Crystal engineering is a field of molecular science that focuses on understanding and controlling how molecules are arranged into crystalline solids. The goal of crystal engineering is to design crystal structures that exhibit desired physical and chemical characteristics, such as enhanced solubility, improved drug dissolution, or specific functional properties.

In this study, we focused on the synthesis, structural characterization, and antibacterial activity of several uracil derivatives. As one of four nucleobases of RNA (ribonucleic acid), uracil and its analogues represent an important class of bioactive molecules. Our findings contribute to the design of new uracil-based antibacterial agents.

CrystEngComm (rsc.li/crystengcomm) is a scientific journal published by the Royal Society of Chemistry (@RoySocChem) dedicated to the design and understanding of crystalline materials.
