Ultrazvuk unapređuje materijale za promjenu faze za pohranu energije
, Kathrin HielscherIstraživači sve više koriste visokoučinsku ultrazvučnu obradu (sonikaciju) kako bi poboljšali učinak materijala s promjenom faze (PCM) koji se koriste u pohrani toplinske energije. Generiranjem intenzivne kavitacije i mikromiješanja, ultrazvuk omogućuje proizvodnju stabilnih PCM disperzija, PCM-a poboljšanih nanočesticama i nanoenkapsuliranih materijala s vrhunskim prijenosom topline i dugoročnom stabilnošću. Studije pokazuju da sonikacija proizvodi homogenije smjese i manje agregate čestica u usporedbi s konvencionalnim metodama miješanja, što dovodi do pouzdanijeg toplinskog ponašanja i poboljšanog učinka pohrane energije.
Napredni ultrazvučni procesori, poput onih koje je razvio Hielscher Ultrasonics, omogućuju preciznu kontrolu nad intenzitetom kavitacije i parametrima obrade, čineći ih moćnim alatima za PCM istraživanje i skalabilnu industrijsku proizvodnju. Tehnologija se već koristi za raspršivanje nanočestica, stvaranje parafinskih voskastih emulzija i izradu mikro- i nano-enkapsuliranih PCM-ova, pomažući istraživačima u razvoju materijala nove generacije za kontrolu klime u zgradama, skladištenje obnovljive energije, hlađenje elektronike i termalno upravljanje baterijama.
Kada žice moraju biti savršeno čiste: ultrazvučno inline čišćenje kao visokotehnološko rješenje
, Kathrin HielscherWhen surface cleanliness becomes a decisive factor in modern wire and cable production, ultrasonic inline cleaning offers a powerful solution. Even microscopic residues such as drawing oils, abrasion particles, or oxide layers can compromise downstream processes like electroplating, coating, welding, or soldering. Ultrasonically assisted systems remove these contaminants efficiently through acoustic cavitation – contact-free, reproducible, and fully integrated into high-speed production lines. Modular solutions such as the Hielscher USCM700 demonstrate how advanced filtration, scalable ultrasonic power, and compact inline design can enhance process stability, reduce chemical consumption, and ensure consistently high surface quality in demanding industrial applications.

Otpad od plastike i gume za jači i dugotrajniji asfalt
, Kathrin HielscherHigh-intensity ultrasonic mixing is emerging as a breakthrough method for turning waste plastic and crumb rubber into high-performance asphalt. Studies show recycled polymers like HDPE, LDPE, and PET can improve rutting resistance, moisture stability, and durability – but only when they are uniformly dispersed in bitumen. Hielscher Ultrasonics enables this with industrial-grade sonicators and a linearly scalable processing approach, allowing asphalt producers to move from lab trials to continuous inline production without changing the core mixing technology. This ultrasonic binder modification method supports stronger roads while helping reduce plastic pollution at scale.

Liposomalni semaglutid mogao bi biti sljedeći veliki iskorak u isporuci GLP-1 lijekova
, Kathrin HielscherSemaglutid i drugi GLP-1 peptidi spadaju među najvažnije moderne terapije, ali znanstvenici koji rade na formulacijama i dalje se suočavaju s osnovnom preprekom: peptidni lijekovi su teški za zaštitu i isporuku, posebno oralnim putem. Čak i odobreni oralni proizvodi sa semaglutidom pokazuju biološku dostupnost ispod 1%, što zahtijeva velike doze i složene strategije formulacije.
A growing technical focus in pharmaceutical development is liposomal encapsulation combined with high-intensity ultrasonic processing. Liposomes can stabilize GLP-1 peptides and enable nano-scale carrier systems, while ultrasound provides reproducible nano-sizing and a scalable manufacturing pathway. Semaglutide is particularly compatible with lipid carriers because studies indicate it can associate with vesicle membranes via its lipid tail, supporting efficient loading into lipid bilayers.
Sonikacija omogućuje novu razinu kontrole u samoorganizaciji celuloznih nanokristala
, Kathrin HielscherSonication holda the key to unlocking more reliable, scalable production of cellulose nanocrystal (CNC) materials. A new study reveals that sonication doesn’t just break up CNC clusters – it actively reshapes how these sustainable nanomaterials self-assemble into cholesteric liquid crystal structures responsible for brilliant structural color. By observing CNC ordering inside tiny evaporating droplets, researchers found that ultrasound can delay gelation, shift kinetic arrest, and tune the helical pitch evolution with remarkable precision. The findings highlight sonication as an industrially relevant processing lever for programming reproducible CNC-based photonic coatings and advanced bio-based materials at scale.

Kako ultrazvučna disperzija poboljšava performanse mokrog kraja i smanjuje troškove
, Kathrin HielscherPapirnici otkrivaju da bolja kemija ne znači uvijek više kemije. Sve veći broj tvornica okreće se ultrazvučnoj disperziji kako bi poboljšali miješanje i aktiviranje dodataka za mokri kraj prije nego što uopće stignu do tvari za papir. Korištenjem visokosnažnog ultrazvuka za razbijanje aglomerata i homogenizaciju kemijskih tokova u liniji, tvornice mogu poboljšati zadržavanje, formiranje i stabilnost procesa dok smanjuju potrošnju kemikalija i energije.

Kako sonikacija može pojačati lizozim za lizu bakterijskih stanica
, Kathrin HielscherSonication boosts lysozyme efficiency in bacterial cell lysis: Researchers find a growing body of research shows that combining lysozyme with ultrasonic sonication dramatically improves bacterial cell lysis in biotechnology and protein production workflows. While lysozyme alone often struggles with dense or over-expressing bacterial cultures, sonication enhances enzyme effectiveness by weakening cell walls through cavitation-driven mechanical forces. The result is faster processing, more complete cell disruption, and higher protein yields. Laboratories increasingly use Hielscher sonicators to precisely control ultrasonic energy, reduce processing time, and achieve reproducible results across research and industrial-scale applications.
